Background: We sought to estimate pooled complication rates of epicardial ventricular tachycardia (VT) ablation from various studies.
Methods: A PUBMED search was done with the search terms ‘Ventricular Tachycardia’, ‘Epicardial’ and ‘Ablation’. Retrospective studies, prospective registries and single center case series with greater than 50 ablation procedures were included in the analysis. Complications were divided into ‘Immediate’ if they occurred within the procedure hospitalization and ‘delayed’ if they occurred after discharge.
Results: We identified 418 articles of which 5 met our inclusion criteria and included a total of 811 patients. About 2/3rd patients had previous endocardial attempt. Pooled rate of immediate complications was 7.16% (58/811). Most common complication was cardiac tamponade/ large pericardial effusion (>200cc) occurring in 35 patients(4.32%). This was followed by access site bleeding (5 cases), refractory VT (4 cases), fatal pulmonary embolism (3 cases), coronary stenosis (2 cases), and extra cardiac bleeding other than access site (one case each of liver perforation, hemoperitoneum, abdominopericaridal fistula, pleural hemorrhage and subdiaphragmatic hematoma). Most common delayed complication was chronic pericarditis with pericardial effusion.
Conclusions: Epicardial VT ablation appears relatively safe when performed in experienced centers. Whether the same safety profile can be attained outside centers of experience remains to be determined.
