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...
متن کاملPercutaneous transvenous Melody valve-in-ring procedure for mitral valve replacement.
OBJECTIVES The purpose of this study was to demonstrate the feasibility of percutaneous transvenous mitral valve-in-ring (VIR) implantation using the Melody valve in an ovine model. BACKGROUND The recurrence of mitral regurgitation following surgical mitral valve (MV) repair in both adult and pediatric patients remains a significant clinical problem. Mitral annuloplasty rings are commonly use...
متن کاملIndications for Mitral Valve Replacement?
Now that it is possible to treat mitral 'valve disease by valve replacement as well as by commissurotomy, and now that it is relatively simple to have either method readily available, it is most important to know which valves should be replaced and which can be safely treated by valvotomy. When the surgeon palpates the valve at operation he may feel stenosis, regurgitation, calcification, or an...
متن کاملMitral Valve Replacement On
Introduction: Cardiac reperfusion injury is a well-described complication occurring after ischemia or following cardioplegic arrest. The primary aim of this study was to evaluate and compare safety of Mitral valve replacement on beating heart without using cross clamp with the conventional Mitral valve replacement. Material and methods: It was a retrospective observational study for study durat...
متن کامل132 Mitral Valve Replacement Versus Mitral Valve Repair
Background Standard mitral valve replacement (MVR) in patients with chronic mitral regurgitation results in consistent reductions in resting postoperative ejection fraction. This has been attributed to removal of the low-impedance ejection pathway into the left atrium or to disruption of the chordal apparatus. Mitral valve repair (MVP) does not reduce ejection fraction at rest. However, whether...
