Background Implantable cardioverter-defibrillator (ICD) therapy is integral to current therapy
for ventricular tachycardia. Patients with an ICD frequently require concomitant …

Endocardial lesions created by radiofrequency catheter ablation are relatively small and
focal. The application of radiofrequency ablation to patients with structural heart disease and …

Ventricular arrhythmias (VA) have been associated with mortality in idiopathic dilated
cardiomyopathy (IDCM). All 3 main mechanisms of arrhythmogenesis—reentry, trigger …

In summary, 3 patients with HC and LV apical diverticula of various sizes are described. All 3
had morphologic evidence of severe midventricular obstruction, including 2 with …

OBJECTIVE: To study electrophysiological characteristics that enable the identification and
ablation of sites of chagasic tachycardia. METHODS: Thirty-one patients with chronic …

We examined the efficacy and safety of ultrasound energy in eliminating the arrhythmogenic
substrates of atrial as well as ventricular tissue using a newly developed instrument in both …

In summary, this case illustrates how complex VT circuits may be. If the findings of this case
are substantiated with additional cases, mapping and radiofrequency energy application …

705 use of antiarrhythmic drugs in some patients sometimes becomes necessary and may
be beneficial. The usefulness of this approach is reflected in the fact that upward of 70% of …

Radiofrequency transcatheter ablation of ventricular tachycardia in the setting of a prior
myocardial infarction is typically performed with application of energy to the left ventricular …

705 use of antiarrhythmic drugs in some patients sometimes becomes necessary and may
