Do bioprosthetic valves require antibiotic prophylaxis?
Patients with mechanical or bioprosthetic valves should receive antibiotic prophylaxis before some dental and surgical procedures to prevent endocarditis. Thrombolytic therapy should be considered in patients who develop a thrombus on a valve that does not resolve with heparin.
What are the disadvantages of biological valves?
The disadvantages of biological heart valves are a smaller valve orifice area (3) and the risk of structural valve degeneration (4), which may necessitate reoperation (table 1).
Do you Premedicate for artificial heart valve?
Patients who have had surgery for placement of prosthetic heart valves or prosthetic intravascular or intracardiac materials are at risk for the development of an infection and should be given premedication according to the 2007 AHA guidelines.
How long does a bioprosthetic valve last?
Because most bioprosthetic valves are free from structural deterioration for 12 –15 years, many patients will die before the valves degenerate. The risk of tissue valve reoperation increases progressively with time, especially in younger patients.
Does aortic valve replacement need antibiotic prophylaxis?
Patients who undergo surgery for prosthetic heart valves or intravascular or intracardiac materials are at risk of infection. Because morbidity and mortality associated with these infections are high, perioperative antibiotic prophylaxis is recommended.
Can you take aspirin with mitral valve prolapse?
Aspirin. If you have mitral valve prolapse and a history of strokes, your doctor might prescribe aspirin to reduce the risk of blood clots.
Does aspirin prophylaxis prevent bleeding in patients with aortic valve replacement?
Background and aims of the study: In patients in sinus rhythm following aortic valve replacement (AVR) with bioprosthetic valves, aspirin prophylaxis generally keeps bleeding complications to a minimum without increasing the risks of thromboembolic events.
Is Coumadin safe after bioprosthetic aortic valve replacement?
A total of 13 studies were identified, which evaluated either no therapy/aspirin or anticoagulation with Coumadin in patients who had undergone bioprosthetic aortic valve replacement. The outcomes in all analyzed studies included venous thromboembolism, stroke, transient ischemic attack, and bleeding events.
When is anticoagulation indicated in patients with bioprosthetic aortic valves?
Conclusions. For patients with bioprosthetic aortic valves, anticoagulation for 3-6 months is indicated in patients with established risk factors, such as atrial fibrillation. Based on recent emerging evidence, anticoagulation and close follow-up should be considered in patients with abnormal echocardiographic or CTA findings,…
Are patients with bioprosthetic mitral valves at increased risk of thrombosis?
In addition, patients with a bioprosthetic mitral valve seem to be at higher risk for thromboembolic events and valve thrombosis (see the Illustrative Case, with Figures 1-2 and Videos 1-2, below). Because bioprosthetic mitral valve replacement is much less common than aortic valve replacement, data are even more limited.
