Transcatheter Closure of Perimembranous Ventricular Septal Defects Using Different Generations of Amplatzer Devices: Multicenter Experience.

Objectives: To demonstrate safety and efficacy of using different generations of softer Amplatzer™ devices for ventricular septal defect (VSD) closure to avoid serious complications at follow-up.

Background: Transcatheter closure of perimembranous ventricular septal defects (PmVSD) is a well-established procedure; however, it is associated with unacceptable incidence of complete heart block. Great advantages have been achieved by using softer devices for VSD transcatheter closure.

Massive aortic root aneurysm in an infant with the Loeys-Dietz syndrome.

A 10-month-old girl with type I Loeys-Dietz syndrome developed a conspicuous aortic root aneurysm that was well demonstrated on chest X-ray/CT reconstruction. She underwent successful valve-spare repair of the ascending aorta.
