Closure of an aortopulmonary window using the Amplatzer Duct Occluder II.

We report two cases of transcatheter-device closure of aortopulmonary windows, a residual defect occurring after previous surgical closure, and a native lesion. The postsurgical defect was closed with an Amplatzer Duct Occluder II (AGA Medical Corporation, MN). The native lesion was not suitable for an Amplatzer Duct Occluder II device; thus, it was closed using an Amplatzer Duct Occluder (AGA Medical Corporation, MN).

Acquired left ventricular to left atrial fistula--not mitral regurgitation! Transcutaneous closure with amplatzer device.

Acquired left ventricle (LV) to left atrial (LA) fistula is a very rare complication following aortic valve replacement (AVR). This can usually be surgically repaired but the risk of re-operation is high due to repeat sternotomy and also due to other comorbidities usually seen in this population. We report a case presenting with recurrent episodes of left ventricular failure 10 years following bioprosthetic aortic valve replacement and who was diagnosed to have a communication between the LV and the LA on transesophageal echocardiography (TEE).

Isolated obstruction of the right ventricular infundibulum in a patient with Williams' syndrome.

Williams' syndrome is a rare condition that is associated with severe cardiovascular manifestations. We report a patient with Williams' syndrome who also has isolated obstruction of the right ventricular infundibulum, an association that, to the best of our knowledge, has not been previously reported.

HELEX Septal Occluder for transcatheter closure of patent foramen ovale: multicentre experience.

Aims: Patients with cryptogenic embolic events and a patent foramen ovale (PFO) are at risk of paradoxical embolism causing recurrent cerebral events; however, transcatheter PFO closure remains controversial. The aim of this multicentre trial was to demonstrate the feasibility and safety of transcatheter closure of PFO with the HELEX Septal Occluder.

Methods And Results: The study enrolled 128 patients (66 female; mean age, 50 years).
