Warfarin therapy with a goal INR of 2.5 to 3.5 is indicated after MV replacement with a mechanical prosthesis. • 3. In this clinical scenario, physicians must be mindful of the thromboembolic and bleeding risks related to chronic anticoagulant therapy. 8.2.3. Patients were randomized in a 1:1 ratio to receive dabigatran 110 mg orally twice a day or dose-adjusted warfarin (INR goal, 2.5) with a primary end point being the presence of new intracardiac thrombus at 90 days. ● For patients with a surgical bioprosthetic aortic or mitral valve, we suggest anticoagulation with a VKA for the first three to six months to achieve an INR of 2.5. Bioprosthetic heart valves are most commonly either made of bovine (cow) or porcine (pig) tissue. Of course the main advantage of a bioprosthetic valve is that there is not typically the need for life long blood thinning medication and therefore a significantly lower risk of bleeding. Annular dehiscence most often is a consequence of infective endocarditis. •Cardiac valvular abnormalities associated with This paper reviews the main heart valve guidelines focusing on the use of oral anticoagulation in these patients. Anticoagulation in Patients with Bioprosthetic Heart Valve Replacements Fibrinolysis Versus Surgery for Prosthetic Valve Thrombosis4. Recurrent Bioprosthetic Mitral Valve Thrombosis Treated with Anticoagulation Robin Fernandes 1, Anubodh Varshney2, and Jayashri Aragam 1Boston VA Medical Center 2Brigham and Women’s Hospital Division of Cardiology July 20, 2020 Abstract Bioprosthetic valve thrombosis (BPVT) is more common than previously thought and likely underreported. • 4. Complications of Bioprosthetic Valve Fracture as an Adjunct to Valve-in-Valve TAVR, Structural Heart, 2019;3:2, 92-99. The FDA has now taken the stance that dabigatran is contraindicated in patients with mechanical heart valves, further noting that its use in bioprosthetic recipients “has not been evaluated and cannot be recommended.” 6,7. Coumadin (Warfarin) Orders (Complete form once at beginning of therapy ) 1. There are almost 100 000 heart valve replacement surgeries in the United States every year. Eleid MF, et al. The On-X Aortic Valve is a newer generation heart valve made of a unique material and design characteristics compared with earlier generations of mechanical heart valves. needed † (1) Bridging anticoagulation during time when INR is subtherapeutic (2a) If VKA therapy interrupted for noncardiac procedures, minimize time subtherapeutic INR. The level of anticoagulation (target INR) is defined by the cardiac surgeon at the time of the operation, and this information needs to be passed on to primary, and secondary care. patients with bioprostheses in the mitral position should receive oral anticoagulants to achieve an INR of 2.5 for the first 3 months. The optimal approach to antiplatelet and anticoagulant therapy after bioprosthetic valve replacement is still under debate. Indications: For use in patients whose mitral valvular disease warrants replacement of their natural or previously placed prosthetic valve and when the valve cannot be repaired. mechanical valve. All mitral valve mechanical valves, and old-style ball and cage aortic valves, are still recommended for the 2.5-3.5 INR goal. There is growing general interest in anticoagulation of mechanical heart valves as well. Valvular Heart Disease: 131. The mean gradient through the prosthesis and the valvular area were obtained. Patients with older-generation mechanical AVR (such as ball-in-cage) Patients with mechanical mitral valve replacement. (1) After aortic valve replacement (AVR) with mechanical prostheses, warfarin is indicated to achieve an INR of 2.0 to 3.0. It is a bovine (cow) heart tissue that has been preserved with a special Edwards technology to reduce calcium build-up on the valve tissue and allow the valve to be stored dry.1 Traditional tissue valves are treated with, and many This article reviews the literature, focusing on publications from the third millennium and the results of mitral valve replacement in children younger than 1 year of age. • Prophylaxis dental therapy was significantly low (p=0.03) in cases with cardiac lesions as compared to controls. It would be reasonable to treat these valve other bileaflet aortic MHVs, albeit with a lower target INR goal (bridging anticoagulation does not need to occur until INR … clinical outcomes between bioprosthetic (bAVR) and mechanical (mAVR) aortic valve replacements (AVR). High-risk patients are considered to be those with concomitant atrial fibrillation, previous thromboembolism, hypercoagulable state or depressed Saxon JT, et al. •Cardiac valvular abnormalities associated with Transcatheter tricuspid valve-in-valve implantation for the treatment of dysfunctional surgical bioprosthetic valves. Annular dehiscence most often is a consequence of infective endocarditis. High-risk patients are considered to be those with concomitant atrial fibrillation, previous thromboembolism, hypercoagulable state or depressed Of these, aortic and mitral valvular disease represent 99% of identified pathology and mortality. Mitral valve. Guidelines vary somewhat between the American Heart Association/American College of Cardiology and the European Society of Cardiology/European Association for Cardio-Thoracic Surgery. Some patients with bio-prosthetic heart valve replacements (or mitral valve repair) also may need anticoagulation. 2016;133:1582. Valve stitches may be everting or noneverting. Currently, only vitamin K antagonists are approved for this indication. Some patients with bio-prosthetic heart valve replacements (or mitral valve repair) also may need anticoagulation. Favor Surgery. In general there are 2 choices for type of surgical heart valve replacement, mechanical valves or bioprosthetic valves. Bioprosthetic Valve. Early anticoagulation for patients with bioprosthetic MVs is controversial. aspirin 81mg, clopidogrel 75 and warfarin INR 2 - 3 Aspirin forever warfarin 3 mo clopidogrel 6 mo. • 5. A 66-year-old female with a bioprosthetic mitral valve presented to an outside hospital with symptoms and signs of congestive heart failure. NSR. • Prophylaxis dental therapy was significantly low (p=0.03) in cases with cardiac lesions as compared to controls. Mitral valve replacement goal INR is. 3 (2.5 - 3.5) Patients who have clotted at a therapeutic INR (2-3) will usually have INR goal raised to. Abstract & Commentary. Mitral bioprostheses are less prone to suffer structural valve deterioration than are aortic bioprostheses. Methods: Adults aged 50 years or older undergoing isolated or concomitant AVR between 2011 and 2017 were included. 11.7% to 13.3% in those aged >75 years.1 Valve-disease– related deaths account for 1.9% of total US mortality. - bioprosthetic valve ทำมาจากอะไร ... mitral valve replacement - lesion แบบไหนควรพิจารณาทำ MVR . Bioprosthetic Valve. All mitral valve mechanical valves, and old-style ball and cage aortic valves, are still recommended for the 2.5-3.5 INR goal. In patients with a bioprosthetic valve in the mitral position, we suggest VKA therapy (target INR, 2.5; range, 2.0-3.0) over no VKA therapy for the first 3 months after valve insertion (Grade 2C). Bioprosthetic (tissue) Valve • Mitral Valve (MVR): Goal INR 2.5: range, 2.0 – 3.0; duration 3 months and then aspirin therapy (81mg/d) Bioprosthetic (tissue) Valve • Aortic Valve (AVR). ● For patients with bioprosthetic aortic or mitral valves, we suggest aspirin 75 to 100 mg per day. The international normalized ratio (INR) recommendations below are per guidelines from the American College of Chest Physicians (2008). Patients with prosthetic heart valves require chronic oral anticoagulation. Valve thrombosis can occur in mechanical prosthetic valves and is increasingly recognised in transcatheter and surgically implanted bioprosthetic valves. A bioprosthetic valve is a replacement valve, usually for the heart, made of either human or animal tissue. Circulation. Special consideration has been given to neonatal and infant valve replacement to provide insights into valve choice and technique. In patients with mechanical valves at low bleeding risk, we suggest the addition of low-dose aspi-rin (50-100 mg/d ) (Grade 1B). Brief summary: mitral bioprostheses. The level of anticoagulation (target INR) is defined by the cardiac surgeon at the time of the operation, and this information needs to be passed on to primary, and secondary care. In pregnant patients with mechanical prosthetic valves who receive Warfarin, the INR goal should be 3.0 (range 2.5 to 3.5). The ACCP guidelines recommend short-term warfarin therapy, with the goal of maintaining an International Normalized Ratio (INR) of 2.5 ± 0.5, after major orthopedic surgery. Periprocedural: The period of time prior to, during, and shortly after an invasive ... INR goal, warfarin dosing and any planned warfarin boost doses iii. mitral stenosis, a mechanical or bioprosthetic heart valve, or mitral valve repair. There are no specific studies evaluating bridging anticoagulation in this patient population. Mechanical mitral valve. Mitral bioprosthetic valve anticoag duration. The risk of thrombosis of mechanical valves is higher in the mitral position compared with aortic position and in older generation valves (ball and cage valves). Per AHA/ACC 2017 guidelines, the goal INR of 3.0 was the recommended value for mitral mechanical prostheses or aortic valve prostheses plus additional thromboembolic risks. Valve replacement – Bioprosthetic Mitral 2.5 (2-3) 3 months ... indication with goal INR ranges (see Appendix I) and potential drug interactions (see Appendix VII). All mitral valve mechanical valves, and old-style ball and cage aortic valves, are still recommended for the 2.5-3.5 INR goal. All mitral valve mechanical valves, and old-style ball and cage aortic valves, are still recommended for the 2.5-3.5 INR goal. Until further higher evidence is available, it is reasonable to target an INR range of 2.5 to 3.5 in patients with risk factors for thromboembolism with low thrombogenic valves, except for On-X valve. Structural valve deterioration is an uncommon cause of pathological regurgitation. Patients undergoing mechanical mitral valve replacement require lifelong anticoagulation. atrial fibrillation, LV dysfunction, or previous thromboembolism) 2017 AHA/ACC VHD section 11.2.2. 1.2 Mechanical heart valve. o Pulmonary valve Bioprosthetic valve: may forgo anticoagulation o Tricuspid valve Bioprosthetic valve, normal ventricular function: low dose aspirin Bioprosthetic valve, decreased right ventricular function or risk factors: warfarin: INR goal of 2.0-3.0 o Aortic and mitral valve follow same guidelines as … target INR 2.0–3.0 at low-risk for thromboembolic events and OAC with target INR 2.5–3.5 in mechani-cal mitral valves and high-risk aortic valve patients (Table 1) [12–13,19–20]. Valvular heart disease (VHD) is a common contributor to cardiac morbidity Warfarin INR 2 - 3 then transition to aspirin indefinite? Rivaroxaban in Patients with Atrial Fibrillation and a Bioprosthetic Mitral Valve [1] ... (titrated to a goal INR of 2-3) and these patients were then followed for 1 year. If the patient has risk factors, warfarin is indicated to achieve an INR of 2.5 to 3.5. In Dual Aortic and Mitral Valve 3 (2.5 -3.5) Chronic Low bleed risk: add aspirin 81 mg Orthopedic Surgery8,9 Total Knee or Hip Arthroplasty* 1.8-2.2 10-14 days INR goal per UWHC Orthopedics Hip Fracture Surgery* 1.8-2.2 10-14 days INR goal per UWHC Orthopedics Trauma Surgery* 1.8-2.2 35 days INR goal per UWHC Orthopedics Many studies suggested that in the early postoperative period slowly raise the level of INR to therapeutic levels is needed, to prevent bleeding events. Transcatheter mitral valve replacement is a new option for patients at high surgical risk who have degenerated surgical mitral valve … When choosing the valve type its important to […] any mechanical valves in the mitral than the aortic position, and, therefore, higher INR levels (2.5 to 3.5) are generally recommended for mechanical mitral valve prostheses. Bioprosthetic SAVR or mitral valve replacement: Anticoagulation with VKA to an INR of 2.5 is reasonable for 3-6 months postoperatively (Class 2b). Aortic valve INR is 2-3; mitral valve INR is 2.5-3.5; Patients with atrial fibrillation should be kept at the higher end of this range. In valve repair patients, we suggest aspirin therapy (Grade 2C). Bioprosthetic valve + history of systemic embolism Goal INR range is 2-3 for at least 3 months, then reassess (Grade 1C) Take a moment to reflect... For which of the following indications for VKA is the recommended intensity goal INR 2.5-3.5? A 25-year study of another bioprosthetic valve, albeit in the mitral position, also gives representative outcomes: thromboembolism 0.5%/valve year, bleeding event 0.7%/valve year, endocarditis 0.4%/valve year, and SVD 2.3%/valve year. Homografts and most bioprosthetic valves in the aortic position do not require long-term anticoagulation, providing … A baseline INR must be resulted prior to the verification of the first dose of warfarin. Special consideration has been given to neonatal and infant valve replacement to provide insights into valve choice and technique. Outcomes/prognosis Development of a thrombus is usually dependent on factors such as valve design, valve material (more common in mechanical versus bioprosthetic valves), location (mitral >aortic position) and subtherapeutic anticoagulation. The goal INR is 3.0 (range, 2.5 to 3.5) for patients with mechanical mitral valves and 3.5 to 4.0 for patients with mechanical tricuspid valves. mitral. Three years prior to the current presentation, her condition was diagnosed as multivessel coronary artery disease and severe ischemic mitral regurgitation during a hospitalization for non-ST-segment elevation myocardial infarction.

Comparison of Antithrombotic Strategies in Chinese Patients in Sinus Rhythm after Bioprosthetic Mitral Valve Replacement: Early Outcomes from a Multicenter Registry in China Cardiovascular Drugs and Therapy. AHA/ACC, ESC, ACCP, and CCS guidelines recommend that all recipients of mechanical prosthetic heart valves be orally anticoagulated (Grade 1), with a target INR between 2.0 and 3.0 for both aortic and mitral valve replacement (MVR) . Valve replacement – Bioprosthetic Mitral 2.5 (2-3) 3 months ... indication with goal INR ranges (see Appendix I) and potential drug interactions (see Appendix VII). This includes the most common which are mitral valve replacement and aortic valve replacement. RIVER followed 1,005 patients from 49 sites in Brazil who had a bioprosthetic mitral valve and atrial fibrillation or flutter for 12 months. The INSPIRIS valve is a resilient heart valve made of RESILIA tissue. … Most patients continue to be treated with aspirin in addition to warfarin for anticoagulation to prevent valve thrombosis. SVD is the most common cause of reoperation for bioprosthetic valves, especially after seven or eight years. Mechanical mitral valve. Goal INR is 2.5 (2-3) for mechanical aortic valve and 3 (2.5-3.5) for mechanical mitral valves, ball-in-cage, or mechanical aortic valve with additional risk factors (e.g. Significant mitral stenosis impedes LVAD inflow, and moderate or worse stenosis should be considered for bioprosthetic valve replacement.13 15 LV decompression reduces the severity of mitral regurgitation (MR).16 Severe MR preimplantation does not require additional intervention.13 Synopsis: Long-term results with the St. Jude valve for isolated mitral valve disease confirm excellent biocompatibility and durability, but these results demonstrate the difficulty of long-term anticoagulation therapy. Contraindications: Do not use if surgeon believes it would be contrary to the patient’s best interests. ... a mechanical or bioprosthetic heart valve, or mitral valve repair. The chordal sparing technique of MV replacement improves LV function and survival. Rheumatic mitral valve disease INR target (range) Atrial fibrillation (AF), prior embolism, and/or left atrial thrombus: 2. EPIC TM / EPIC TM SUPRA STENTED PORCINE TISSUE VALVES INDICATION FOR USE The Epic TM valve is indicated for patients requiring replacement of a diseased, damaged, or malfunctioning native aortic and/or mitral heart valve. The INSPIRIS RESILIA valve is from Edward Lifesciences, the company trusted by surgeons for more than 60 years to deliver safe, … Rivaroxaban in Patients with Atrial Fibrillation and a Bioprosthetic Mitral Valve [1] ... (titrated to a goal INR of 2-3) and these patients were then followed for 1 year. Generally, goal INR is 2.5 to 3.5 for MVR and AVR if any other risk factors present (A-fib, prior thromboembolic event, LV dysfunction, hypercoagulable state); 2-3 is ok with AVR without any other risk factors. Bioprosthetic Thrombosis Followed by Prosthetic Degeneration. The choice of valve depends on valve durability, the need for antithrombotic therapy, and patient preferences.1 2 Mechanical heart valves are preferred in patients under 65.3 Bioprosthetic valves do not require lifelong anticoagulation but have a greater rate of … mechanical valve. In pregnant women with mechanical prosthetic valves, Warfarin should be discontinued 2–3 weeks before planned delivery, and replaced with either a continuous intravenous UFH or a dose-adjusted LMWH. Indication and Target INR Atrial Fibrillation / Atrial Flutter (INR 2-3, Goal 2.5) (2) After mitral valve replacement (MVR) with mechanical valve, is indicated warfarin to achieve an INR of 2.5 to 3.5. • 4. Patients in the bioprosthetic group had a higher incidence of all-cause mortality. Background: To identify the optimal use of anticoagulants after Carpentier-Edwards valve replacement, a retrospective study of all patients undergoing Carpentier-Edwards aortic (N = 378) or mitral (N = 370) valve replacement was done. It may also be used as a replacement for a previously implanted aortic and/or mitral prosthetic heart valve. Administering daily low-dose aspirin (75 mg to 100 mg) indefinitely and a VKA to obtain an INR goal of 2-3 for the first 3 months is reasonable for patients with a … Patient presenting in November 2011 with mitral bioprosthetic valve thrombosis (BPVT) (left panels); note presence of soft echodensities on the prosthetic cusps (top left, arrows) resulting in restricted systolic opening on the 3-dimensional left ventricular view (bottom left). The incidence of mechanical valve thrombosis is 0.5 to 8 percent for left-sided mechanical valves and 20 percent for right-sided valves (likely attributable to lower flow and gradient).

Favor Fibrinolysis. For patients with a bioprosthetic valve in the mitral position, therapy with warfarin to a target INR of 2.5 (range, 2.0-3.0) for the first 3 months after valve insertion is recommended. Mitral bioprostheses are less prone to suffer structural valve deterioration than are aortic bioprostheses. Source: Remadi JP, et al. Repeat operation in the first 10 years following mitral valve replacement is required in as many as 35 percent of patients. Valve replacement or repair is the definitive treatment in those with severe valvular heart disease. Multivariable logistic regression analysis was used to evaluate the risk- prosthesis.3 Patients with bioprosthetic heart valves are at a lower risk of thrombosis, but the risk is not zero. Risk of throm-bosis in patients who receive a bioprosthetic valve increases in the setting of concurrent AF or mitral stenosis (MS).4 Porcine valves confer … Mitral valve is approximate twice the risk as aortic valve. The INR target (range) is 2.5 (2.0-3.0) in all of the following circumstances: Ischemic stroke, transient ischemic attack (TIA), or systemic embolism. Risk factors (age >75 years, hypertension, diabetes mellitus, decreased left ventricular systolic function, heart failure) The study was stopped early due to low enrollment. Goal INR is 2.5 (2-3) for mechanical aortic valve and 3 (2.5-3.5) for mechanical mitral valves, ball-in-cage, or mechanical aortic valve with additional risk factors (e.g. target INR 2.0–3.0 at low-risk for thromboembolic events and OAC with target INR 2.5–3.5 in mechani-cal mitral valves and high-risk aortic valve patients (Table 1) [12–13,19–20]. atrial fibrillation, LV dysfunction, or previous thromboembolism) 2017 AHA/ACC VHD section 11.2.2. Standard medical treatment after the MitraClip procedure, in the absence of risk factors requiring antithrombotic therapy such as atrial fibrillation, is dual antiplatelet therapy using aspirin and clopidogrel. Precision Anticoagulation Medicine: 77. • In patients with a bioprosthetic mitral valve who are in sinus rhythm and have no other indications for anticoagulant therapy, 3 months of warfarin therapy (international normalized ratio [INR] range: 2.0-3.0) is suggested, to be followed by long-term acetyl salicylic acid (ASA) (81 mg) therapy. The On-X Aortic Valve is the only mechanical valve with FDA and CE approval to be used safely with less blood thinner (warfarin). The use of bioprosthetic aortic valve replacement (bAVR) has become a common solution for the treatment of valvular heart disease.23 Bioprosthetic valves have a low long-term thromboembolic risk and therefore do not require lifelong anticoagulation. Long-term anticoagulant therapy is required in patients with atrial fibrillation (AF) and needed † (1) Bridging anticoagulation during time when INR is subtherapeutic (2a) If VKA therapy interrupted for noncardiac procedures, minimize time subtherapeutic INR. It is recommended that patients with bioprosthetic valves in the mitral position, and sometimes in the aortic position, should be anticoagulated with warfarin for three months with a goal INR … The INR goal in high-risk On-X aortic valve Aortic bioprosthetic valve ... duration. In patients with a bioprosthetic mitral valve who are in sinus rhythm and have no other indications for anticoagulant therapy, 3 months of warfarin therapy (international normalized ratio [INR] range: 2.0-3.0) after valve replacement is suggested, to be followed by … A baseline INR must be resulted prior to the verification of the first dose of warfarin. Heart valve replacement. Medium-term follow-up has been completed and longer term follow-up is in progress. The diagnosis of bioprosthetic mitral valve thrombosis was established 48.7+/-55.2 months after surgery. The primary outcome was 5-year hospital readmission. Structural valve deterioration is an uncommon cause of pathological regurgitation. Mechanical valve prosthesis: The use of direct thrombin inhibitors (dabigatran) or anti-Xa direct oral … Of the 11 patients who died at follow-up, 2 had undergone aortic valve replacement, 6 had undergone mitral valve replacement, and 3 had undergone mitral valve repair. Patients were randomized 1:1 to rivaroxaban 20 mg once daily (15 mg daily in case of renal dysfunction) or warfarin dose-adjusted to an INR of 2.0-3.0.) no other indication for warfarin therapy: ASA (50 to 100 mg/day) Bioprosthetic (tissue) Valve-history of systemic embolism: Range: 2.0 -3.0 Targeted INR: 2.5 There is a paucity of data to justify the INR goal of 2 to 3 in high-risk patients. • 5. McElhinney DB, et al. Goal INR 2.5-3.5 (target 3.0) Patients with mechanical AVR with risk factors. Which has a higher thromboembolic risk aortic or mitral valve. The target INR takes into account patient risk factors and the thrombogenicity of the prosthetic valve: Antithrombotic therapy – mechanical prosthetic valves INR 2.0 – 3.0 INR 2.5 – 3.5 AVR low risk √ AVR high risk √ MVR √ AVR – aortic valve replacement MVR – mitral valve replacement Mitral Valve Replacement with the St. Jude Prosthesis. INR goal 2.5† (1) INR goal 3.0 (1) If antiplatelet Rx Indicated, add ASA 75-100mg (2b) No bridging . Patients randomized to warfarin had a target INR of 2 to 3 if they had a mechanical aortic valve with no additional risk factors and a target INR of 2.5 to 3.5 if they had a mechanical aortic valve with additional risk factors (eg, previous thromboembolism, MS) or a mechanical mitral valve. Background: Incidence of stroke within 30 days after percutaneous mitral valve repair using the MitraClip varies from 0.7% and 2.6% between registries. valves (Grade 1B): target INR 2.5 for aortic (Grade 1B) and 3.0 for mitral or double valve (Grade 2C). • 3.
