Bioprosthetic Mitral Valve Regurgitation
The usefulness of two-dimensional color-Doppler flow-imaging (2D Doppler) in the detection, localization, and quantitation of bioprosthetic mitral valve regurgitation is uncertain. Mitral bioprostheses, before and after the creation of transvalvular (n = 33), paravalvular (n = 17), or combined (n = 23) defects, were mounted in a pulsed duplication system (flow rates, 2.5-6.5 1/min; pulse rate, ...
متن کاملTranscatheter valve-in-valve implantation for failed bioprosthetic heart valves.
BACKGROUND The majority of prosthetic heart valves currently implanted are tissue valves that can be expected to degenerate with time and eventually fail. Repeat cardiac surgery to replace these valves is associated with significant morbidity and mortality. Transcatheter heart valve implantation within a failed bioprosthesis, a "valve-in-valve" procedure, may offer a less invasive alternative. ...
متن کاملTranscatheter valve-in-valve implantation for failed surgical bioprosthetic valves.
When bioprosthetic cardiac valves fail, reoperative valve replacement carries a higher risk of morbidity and mortality compared with initial valve replacement. Transcatheter heart valve implantation may be a viable alternative to surgical aortic valve replacement for high-risk patients with native aortic stenosis, and valve-in-valve (V-in-V) implantation has been successfully performed for fail...
متن کاملEarly bioprosthetic valve calcification with alfacalcidol supplementation
We report a case of early bioprosthetic valve calcification in a 76 year-old woman who had received supplementation with alfacalcidol, an analogue of vitamin D, for 3 years after her initial valve replacement. She underwent aortic valve replacement at the age of 71 and subsequently complained of shortness of breath. Ultrasonic cardiography revealed severe aortic stenosis and we performed a seco...
متن کاملBalloon Valvuloplasty for Bioprosthetic Tricuspid Valve Stenosis
A 73-year-old woman was admitted to our hospital for a scheduled percutaneous transcatheter balloon valvuloplasty of a stenotic tricuspid bioprosthesis. The patient had a history consistent with exertional dyspnea, abdominal distension, and edema of the lower extremities resistant to diuretic treatment over the previous few months. Forty-three years prior, she underwent aortic valve replacement...
