Aortic valve replacement with the Björk-Shiley tilting disc valve prosthesis. Clinical experiences in 50 cases.
Single aortic valve replacement with the Björk-Shiley tilting disc valve prosthesis has been performed in 50 patients since April 1971. None of the total of six deaths (12.0%) was attributable to malfunction of the prosthesis or to embolic complications. Follow-up examination showed insignificant or moderate prosthetic regurgitation in two patients and moderate paravalvular leakage in one patie...
متن کاملDoppler-Catheter Gradient Relation for Bileaflet Aortic Valve Prostheses
Background. Considerable discrepancies between Doppler and catheter gradients caused by localized gradients and pressure recovery have been reported for normal bileaflet aortic valve prostheses. Methods and Results. To examine whether this Doppler-catheter gradient relation is affected by prosthetic valve malfunction, a 19-mm CarboMedics aortic valve was simultaneously studied with continuous-w...
متن کاملObstructed tilting disc mitral valve prosthesis associated with placenta praevia.
The occurrence of a bleeding placenta praevia in a young woman, with a viable fetus and an acutely obstructed Lillehei-Kaster valve, provided serious difficulties in priorities and decision making. This has prompted an analysis of the problems which others may encounter.
متن کاملTranscatheter CoreValve valve-in-valve implantation in a stentless porcine aortic valve for severe aortic regurgitation
KEY CLINICAL MESSAGE We describe the first valve-in-valve Corevalve transcatheter aortic valve replacement in the St. Jude Toronto stentless porcine aortic valve in the United States, which enabled this 59-year-old patient with a history of bacterial endocarditis and aortic regurgitation to avoid heart transplant with complete resolution of his severe left ventricular dysfunction.
متن کاملIntermediate-term results after the aortic valve replacement using bileaflet mechanical prosthetic valve in children.
OBJECTIVE Intermediate/long-term results after aortic valve replacement using bileaflet mechanical valve in children should be clarified as a standard of treatment of aortic valve disease in children. METHODS Forty-five patients aged under 15 years underwent 46 aortic valve replacements using bileaflet mechanical prosthetic valve. Patients' ages ranged from 1 to 15 years (9 years as a median ...
