Prevalence and long-term predictors of left ventricular hypertrophy, late hypertension, and hypertensive response to exercise after successful aortic coarctation repair.

Controversial data exist about the long-term results of aortic coarctation (AC) repair. This study explored the prevalence and predictors of left ventricular (LV) hypertrophy, late hypertension, and hypertensive response to exercise in 48 subjects (age, 15.1 ± 9.

[Transcatheter treatment of patent ductus arteriosus].

Isolated patent ductus arteriosus accounts for 10 to 18% of all cardiovascular malformations. Transcatheter closure of the patent ductus arteriosus has now become established practice with a high success rate and a low incidence of complications. Many devices have been proposed during the last 20 years.

Transcatheter closure of residual atrial septal defects after surgical closure.

The repair of an ostium secundum atrial septal defects (ASDs) by an open heart operation is a safe procedure associated with low mortality and morbidity. Transcatheter closure of ASDs is a less invasive method of repairing ASDs and may also be the procedure of first choice in residual postsurgical ASD.

Transcatheter closure of congenital and acquired muscular ventricular septal defects using the Amplatzer device.

Surgical closure of congenital or post-myocardial infarction (MI) muscular ventricular septal defect (MVSD) is associated with significant mortality and morbidity; therefore, both surgeons and cardiologists would welcome a safe non-surgical approach. The aim of this study is to report the combined experience of 2 cardiac centers in the transcatheter occlusion of both congenital and acquired MVSDs using the Amplatzer MVSD occluder device (AGA Medical Corporation, Golden Valley, Minnesota). Thirty-two patients underwent attempted transcatheter closure of an MVSD.

Early and late complications associated with transcatheter occlusion of secundum atrial septal defect.

Objectives: The goal of this study was to report the early and late complications experienced in atrial septal defect (ASD) transcatheter closure.

Background: Atrial septal defect transcatheter occlusion techniques have become an alternative to surgical procedures. A number of different devices are available for transcatheter ASD closure.
