Ventricular Tachycardia Clinical Trial
Official title:
Phase I/II Study of EP-guided Noninvasive Cardiac Radioablation for Treatment of Ventricular Tachycardia
Phase I/II Study of EP-guided Noninvasive Cardiac Radioablation (ENCORE) for Treatment of Ventricular Tachycardia
Patients with Ventricular Tachycardia (VT) who have failed standard therapy (medicines, invasive catheter ablation) have limited options, with one-year survival below 20%. Preclinical data demonstrate that single fraction stereotactic body radiotherapy (SBRT) to discrete portions of the heart is feasible and may result in a reduction or elimination of VT. The efficacy may be further improved when guided by cardiac electrophysiologic (EP) testing. In total, the mapping and ablation proposed for this EP-guided Noninvasive Cardiac Radioablation (ENCORE) is a rapid and totally non-invasive method. Overall safety and early efficacy of ENCORE have not been rigorously studied in a prospective trial to-date. The purpose of this phase I/II study is to demonstrate the short-term safety and preliminary efficacy of ENCORE for patients with life-threatening, treatment-refractory VT. ;
