A papillary-ventricular complex repair technique for functional mitral regurgitation.
The objective of this study was to describe a simple and reproducible papillary-ventricular complex technique for repairing functional mitral regurgitation. To avoid a recurrence of mitral regurgitation subsequent to left ventricular remodelling, we performed papillary muscle plication and papillary muscle and head approximation in combination with relocation of the papillary muscle heads to co...
متن کاملMitral valve plasty for mitral regurgitation after blunt chest trauma.
A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions...
متن کاملPapillary muscle suspension concomitant with approximation for functional mitral regurgitation.
BACKGROUND Papillary muscle (PM) suspension concomitant with mitral annuloplasty and PM approximation (PMA) has been developed for functional mitral regurgitation (MR). In the present study, the early effect of PM suspension (PMS) on the postoperative mitral geometry and diastolic mitral tethering was investigated. METHODS AND RESULTS Subjects were 22 patients with left ventricular dysfunctio...
متن کاملPersistent reduction of ischemic mitral regurgitation by papillary muscle repositioning: structural stabilization of the papillary muscle-ventricular wall complex.
BACKGROUND Recurrent ischemic mitral regurgitation (IMR) is frequent despite initial reduction by annuloplasty because continued LV remodeling increases tethering to the infarcted papillary muscle (PM). We have previously shown that PM repositioning by an external patch device can acutely reduce IMR. In this study, we tested the hypothesis that IMR reduction persists despite possible continued ...
متن کاملMassive mitral regurgitation secondary to acute ischemic papillary muscle rupture: the role of echocardiography.
Papillary muscle rupture is an infrequent but often fatal mechanical complication of acute myocardial infarction (AMI). We report the case of an AMI complicated by the development of an abrupt cardiogenic shock due to the rupture of the head of the postero-medial papillary muscle with echocardiographic demonstration of severe mitral regurgitation due to flail posterior mitral valve leaflet. Aft...
