Outcomes 15 years after valve replacement with a mechanical versus a bioprosthetic valve: final report of the Veterans Affairs randomized trial.
OBJECTIVES The goal of this study was to compare long-term survival and valve-related complications between bioprosthetic and mechanical heart valves. BACKGROUND Different heart valves may have different patient outcomes. METHODS Five hundred seventy-five patients undergoing single aortic valve replacement (AVR) or mitral valve replacement (MVR) at 13 VA medical centers were randomized to r...
متن کاملMechanical versus bioprosthetic valve replacement in middle-aged patients.
OBJECTIVE The current trend towards decreasing the age for selection of a tissue over a mechanical prosthesis has led to a dilemma for patients aged 50-65 years. This cohort study examines the long-term outcomes of mechanical versus bioprosthetic valves in middle-aged patients. METHODS Patients (N = 659) aged between 50 and 65 years who had first-time aortic valve replacement (AVR) and/or mit...
متن کاملAortic valve replacement in patients over 70 years.
Twenty-seven patients 70 years of age or more were operated upon with aortic valvular replacement with an early mortality rate of 7%. No more patients died during a mean follow-up period of 28 months. The Björk-Shiley standard tilting disc valve was implanted in 15 cases and the new convexo-concave model in 12 cases. Sixty-seven per cent of the patients had narrow aortic roots (21 and 23 mm pro...
متن کاملVery long-term survival implications of heart valve replacement with tissue versus mechanical prostheses in adults <60 years of age.
BACKGROUND Several centers favor replacing a diseased native heart valve with a tissue rather than a mechanical prosthesis, even in younger adult patients. However, long-term data supporting this approach are lacking. We examined the survival implications of selecting a tissue versus a mechanical prosthesis at initial left-heart valve replacement in a cohort of adults <60 years of age who were ...
متن کاملSurvival and outcomes following bioprosthetic vs mechanical mitral valve replacement in patients aged 50 to 69 years.
IMPORTANCE In nonelderly patients with mitral disease requiring valve replacement, deciding between bioprosthetic and mechanical prosthetic valves is challenging because long-term survival and morbidity are not well defined. OBJECTIVE To quantify survival and major morbidity after mitral valve replacement in patients aged 50 to 69 years. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohor...
