Transcatheter aortic valve implantation is an emerging treatment option for severe symptomatic aortic stenosis in patients considered unsuitable for surgical valve replacement. The authors review the use of multislice computed tomography in the selection of candidates for transcatheter aortic valve replacement, procedural support and post-interventional(More)
INTRODUCTION Despite rapid advances in transcatheter aortic valve prostheses, anatomical constraints remain that can limit access to this treatment for patients with severe aortic stenosis. The objective of this study was to determine the proportion of patients anatomically suitable for this technique using the different devices and approaches available. (More)
Isolated left ventricular noncompaction (LVNC) is a rare cardiomyopathy characterized by excessive and prominent trabeculations associated with deep recesses that communicate with the ventricular cavity. Determining the natural history of this condition has been hampered by differences in clinical features and prognosis in published series, which are partly(More)
Sudden cardiac death (SCD) can be the first clinical manifestation of Wolff-Parkinson-White (WPW) syndrome. Catheter ablation of accessory pathways is now a safe and effective procedure, and is widely recommended in patients with WPW syndrome. However, management of the asymptomatic WPW patient remains controversial. Recent studies have readdressed the(More)
The Parachute is a novel left ventricular (LV) partitioning device that is deployed percutaneously in the left ventricle in patients with anteroapical regional wall motion abnormalities, dilated LV and systolic dysfunction after anterior myocardial infarction (MI). The implantable device is a partitioning membrane that isolates the dysfunctional region of(More)
