Mitral valve in secundum atrial septal defects.
The mitral valve in 15 of 16 adult hearts with unclosed secundum atrial septal defects showed a consistent abnormality consisting of thickening of the medial half of the anterior cusp and some fusion of adjacent chordae. Histologically the lesion is a surface fibrosis without vascularisation or myxomatous change to suggest a rheumatic or floppy valve. The high frequency and morphological appear...
متن کاملArtificial chordae for pediatric mitral and tricuspid valve repair.
OBJECTIVE To evaluate pediatric atrioventricular valve repair with artificial chordae. METHODS Between February 2001 and January 2006, artificial chords were used in 21 children with severe mitral or tricuspid valve regurgitation. Patients with AVSD were excluded. Median age was 84 (1-194) months. Five patients had isolated tricuspid valve anomalies, 16 had mitral valve anomalies (associated ...
متن کاملMitral and Tricuspid Valve Closure
Echocardiography was used to evaluate mitral and tricuspid valve closure in patients 1 day to 20 years of age. When possible, simultaneous phonocardiograms were obtained. The difference in time between the Q wave of the electrocardiogram and mitral closure and between Q and tricuspid closure was designated the delta value (A). Four groups of patients were assessed: 1) normals (40), secundum atr...
متن کاملMitral Annular Kinetics, Left Atrial, and Left Ventricular Diastolic Function Post Mitral Valve Repair in Degenerative Mitral Regurgitation
OBJECTIVE The relationship of mitral annular (MA) kinetics to left ventricular (LV) and left atrial (LA) function before and after mitral valve (MV) repair has not been well studied. Here we sought to provide comprehensive analysis that relates to MA motions, and LA and LV diastolic function post MV repair. METHODS Three-dimensional analyses of mitral annular motion, LA function, and LV volum...
متن کاملRole of tricuspid valve repair for moderate tricuspid regurgitation during minimally invasive mitral valve surgery.
BACKGROUND The aim of this study was to investigate the impact of short- and mid-term survival of tricuspid valve (TV) repair versus conservative therapy in patients with preoperative moderate functional tricuspid regurgitation (TR) undergoing minimally invasive mitral valve (MV) surgery. METHODS Between January 2002 and December 2009, a total of 430 patients with pure mitral regurgitation an...
