摘要: Background Epicardial ablation has been shown to be a useful adjunct for treatment of ventricular tachycardia (VT). Objective To report the trends, safety, and efficacy epicardial mapping at single center over an 8-year period. Methods Patients referred VT (June 2004 July 2011) were divided into 3 groups: ischemic cardiomyopathy (ICM), nonischemic (NICM), idiopathic arrhythmias (VA). with scar-mediated who underwent combined endocardial (epi-endo) compared those endocardial-only (endo-only) regard patient characteristics, acute procedural success, 6- 12-month clinical outcomes. Results Among 144 patients ablation, 95 109 procedures (94% access rate). Major complications seen in 8 (8.8%) pericardial bleeding (>80 cm ) 6 cases (6.7%), although no tamponade, surgical intervention, or mortality was seen. ICM epi-endo had improved freedom from endo-only 12 months (85% vs 56%; P = .03). In NICM, differences between (36% 33%; 1.0). VA, only 2 17 successfully ablated epicardium. Conclusions this large tertiary single-center experience, complication rates are acceptably low outcomes associated ICM. NICM represent growing population, recurrence remains high despite ablation. yield VA.
