New technology: valve repair using biodegradable rings.
OBJECTIVE To introduce a new concept in the annuloplasty technology. Although rigid and flexible rings meet the basic needs of adults, they do not preserve the changes in shape and size occurring during the cardiac cycle. If implanted in children, such materials do not allow growth of the native annulus. METHODS From March 2003 to March 2007, 207 patients underwent mitral and/or tricuspid val...
متن کاملSurgically created double-orifice left atrioventricular valve: a valve-sparing repair in selected atrioventricular septal defects.
OBJECTIVES Some features of the left atrioventricular valve (large mural leaflet, dystrophic tissue) represent a challenge for repair of atrioventricular septal defects without postoperative regurgitation. A retrospective study was conducted to evaluate the results of surgically creating a double-orifice left atrioventricular valve in such circumstances. Clinical results were analyzed according...
متن کاملFlexible versus nonflexible mitral valve rings for congestive heart failure: differential durability of repair.
BACKGROUND Surgical intervention is playing an increasingly important therapeutic role in congestive heart failure (CHF) patients with ischemia and dilated cardiomyopathy. Their mitral regurgitation (MR) is a result of left ventricular (LV) geometrical distortion. The optimal type of ring for CHF patients with geometric ventricular-based MR is unknown. This study reviewed the results of flexibl...
متن کاملRepair of atrioventricular valve regurgitation in the modified Fontan operation.
OBJECTIVE To evaluate the prevalence, impact and outcome of repair of atrioventricular valve regurgitation (AVVR) in Fontan patients. METHODS We retrospectively reviewed 340 Fontan patients from 1986 to 2001. Twelve patients with valve closure or replacements were excluded. AVVR was graded by transthoracic echocardiography. Patients were divided into group O (no AVVR), group A (1+ to 2+) and ...
متن کاملA novel repair for patients with atrioventricular septal defect requiring reoperation for left atrioventricular valve regurgitation.
OBJECTIVE Left atrioventricular valve regurgitation (LAVVR) is the most frequent indication for reoperation following atrioventricular septal defect (AVSD) repair. We estimate from our experience that within 10 years of initial repair, 14% of patients undergoing repair of atrioventricular septal defect (AVSD) require reoperation for this complication. We have developed a novel leaflet augmentat...
