Randomized trial of partial versus complete chordal preservation methods of mitral valve replacement: A preliminary report.
BACKGROUND The merits of retaining the subvalvular apparatus during mitral valve replacement for chronic mitral regurgitation have been demonstrated in numerous clinical and laboratory investigations. In this preliminary report, we analyzed the early effects of complete versus partial chordal preservation on left ventricular mechanics. METHODS AND RESULTS Fifty patients undergoing isolated su...
متن کاملAn unusual complication after chordal sparing mitral valve replacement.
Clinical Summary A 44-year-old man with cardiac failure was admitted to our clinic for increasing dyspnea. Transesophageal echocardiography showed severe mitral regurgitation with a prolapse of the anterior leaflet. Aortic regurgitation was referred to as mild. End-diastolic diameter was 73 mm, end-systolic diameter was 47 mm, and ejection fraction was calculated to be 0.50. Catheterization rev...
متن کامل[Left ventricular rupture following mitral valve replacement].
Rupture of the posterior wall of the left ventricle is an unusual but often lethal complication following mitral valve replacement. The incidence is about 1% of MVRs. Most of the ruptures are attributed either to technical maneuvers in the operation or to stretch injury produced by removal of the mural leaflet of the mitral valve. Surgical repair of the rupture requires the cardiopulmonary bypa...
متن کاملLeft Ventricular Rupture Following Mitral Valve Replacement*
During a 10-year period, we have encountered 6 patients (mean age, 61.2 years) with left ventricular rupture following mitral valve replacement, with an overall incidence of 1.8 percent. Four patients had early rupture, one had delayed rupture, and one had late rupture with a false aneurysm formation. Among four patients with early niptare, there were two patients with external repair by using ...
متن کاملLeft Ventricular Rupture Post Mitral Valve Replacement
Prevention is better than cure best applies here. As per many authors, posterior leaflet chordae preservation prevent Left ventricular rupture (LVR) and preserve LV geometry. We are presenting here 5 types of left ventricular rupture (LVR) post Mitral valve replacement (MVR) with different methods to repair with the advantages and disadvantages of each. The mortality rate is still very high des...
