Background: Ablation of ventricular tachycardia (VT) reduces implantable cardioverter defibrillator shocks. Intracardiac ultrasound (ICE) can visualize and quantify the function of all left ventricular wall segments. We thus hypothesized that ICE could identify scar tissue and provide a guide to facilitate substrate‐guided VT ablation.
Methods: Eighteen patients underwent VT...
Nonsurgical subxiphoid pericardial access may be useful in ventricular tachycardia ablation and other electrophysiologic procedures but has a risk of right ventricular puncture.The purpose of this study was to identify a signature pressure frequency that would help identify the pericardial space and guide access.The study consisted of 20 patients (8 women and 12 men; mean age 59.1 ± 14.2 years; left...
