Hemodynamic State Early after Prosthetic Replacement of Mitral Valve

Hemodynamic state early after prosthetic replacement of mitral valve.

PATIENTS undergoing replacement of the mitral valve appear to have somewhat less satisfactory early and late results than do those undergoing replacement of the aortic valve, in our experience." 2 Therefore studies were made of the hemodynamic state preoperatively and early postoperatively in patients in whom the Starr-Edwards prosthesis was inserted into the mitral region. The data indicate th...

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...

Right sided heart evaluation after successful mitral valve replacement.

Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...

Prosthetic replacement of the mitral valve.

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.
