Mitral valve replacement with maximum chordal preservation in a rheumatic population at Da Nang hospital.
Main Article Content
Abstract
The aim of this study is to investigate theeffect of chordal-sparing mitral valve replacement proceduresin a rheumatic population.Between January and December 2015, 36 patients underwent mitral valve replacement for rheumatic heart disease at Da Nang hospital.Reduction of left ventricular end-systolic and end-diastolic diameteris significant postoperative as compared to preoperative (p <0,01), but ejection fraction do not change statistically.There is no death ormyocardial rupture.Echocardiographic follow-up is complete and there has been no evidence of left ventricular outflow tract obstruction or interference with prosthetic valve function by the retained subvalvular structures.We conclude that maximum chordal preservation is possible in the large majority of rheumatic patients with acceptable operativemortality and satisfactory short-term results
