Prosthetic cardiac valve replacement

Prosthetic valve replacement.

1 find it somewhat surprising that after twcnty years of valve replacement the subject is stiii a topic for discussion at major cardiac surgical meetings. This undoubt ediy reflects the status of valves today since there stili rernains no ideal vaive substitute. In fact in recent years there appears te be a general trend toward trying to preserve the patient's own natural valve by rather extens...

Prosthetic valve leakage following cardiac valve replacements.

Thirty cases were evaluated in order to study the etiology of prosthetic valvular dehiscence in view of its continued occurrence in a small percentage of cases. The clinical course, management, initial valvular pathology, as well as findings at reoperation and necropsy were the main basis of this study. Factors in the genesis of prosthetic valvular dehiscence in the early and late groups seemed...

Hemodynamic function of the Kay-Shiley prosthetic cardiac valve. Observations after mitral or tricuspid valve replacement.

Eighteen patients were catheterized before and nine months (average) after mitral and/or tricuspid valve replacement with the KayShiley prosthesis. In 14 patients with Kay-Shiley mitral prostheses, average cardiac index rose from 2.2 L/min/M"reoperatively to 2.8 postoperation, average left atrial mean pressure fell from 26 to 18 mm Hg, and the average left atrioventricular mean diastolic gradie...

Cardioversion following prosthetic mitral valve replacement.

SUMMARY Direct current conversion of atrial fibrillation has been attempted in 60 consecutive patients following prosthetic mitral valve replacement (Starr-Edwards prosthesis). Sinus rhythm was attained and persisted for at least 24 hours after the procedure in 68% (41 patients) and 40% of the entire group (24 patients) were still in normal sinus rhythm an average of 10 months later. Successful...
