A fascia lata mitral valve based on the 'frustum' principle.
نویسندگان
چکیده
A newly designed strut-supported 'frustum' fascia lata valve has been described for replacement of the mitral valve. It offers the advantages of autologous tissue leaflets, ease of construction and insertion, central flow through an unobstructed mobile annulus, no ventricular outflow obstruction, and minimal intracardiac prosthetic material. Initial clinical trials which have been carried out suggest that the action of this valve allows a close approximation of the haemodynamics and movement of the normal mitral valve.

Clinical and Hemodynamic Results of Mitral Valve Replacement with Autologous Fascia Lata Grafts
Nine patients with severe mitral disease were studied before and six months after mitral valve replacement with a three-cusp stented prosthesis using fresh autologous fascia lata tissue. Only patients in whom there was no auscultatory and angiographic evidence of incompetence of the replaced valve were selected for restudy. All patients claimed a marked improvement in their exercise capacity af...

Sixty-seven metal-frame-supported autologous fascia lata mitral valves were placed in 67 patients. There was an operative mortality of 25% and an overall mortality of 40% within 20 months. Most of the late deaths were due to valve malfunction which occurred in 50% of survivors. Female patients demonstrated a much higher rate of valve dysfunction than did men. This malfunction of the fascial val...

Sixteen frame-mounted fascia lata valves removed from the mitral, aortic or--in one patient--pulmonary position have been detailed histologically. These valves had remained in 15 patients (11 men and four women) for periods varying between 10 and 44 months. The reason for the original transplantation was either chronic rheumatic endocarditis or calcific aortic disease. In the mitral position, t...

متن کاملHaemodynamic results of replacement of mitral and aortic valves with autologous fascia lata prostheses.
Twelve patients undergoing aortic and 28 undergoing mitral valve replacement with autologous fascia lata valves were studied before and six months after surgery. One aortic and 10 mitral valves were found to be significantly incompetent. Of the incompetent mitral valves, two appeared to have perivalvular leaks. Six of the remainder were associated with abnormal ventricular filling patterns. Val...
