Background: Safety outcomes of percutaneous epicardial ventricular tachycardia (VT) ablations vary widely in the literature. This is likely related to small sample sizes and heterogeneous patient and substrate characteristics between different studies. We aimed to perform a systematic review of safety outcomes following percutaneous epicardial VT procedures.
Methods: PubMed, EMBASE, and Cochrane Central were searched for studies that reported procedural complications of percutaneous epicardial access and mapping or ablation for VT. There were no restrictions with regards to the arrhythmogenic substrate. The overall complication rates were calculated among all included studies.
Results: The search yielded 465 results. A total of 32 studies, 1,972 patients, and 2,047 procedures were included. Approximately 1/3 of substrates were ischemic and 2/3 of patients were men. Successful percutaneous epicardial access was achieved in 92.6% of cases. Table 1 reports the pooled incidence of adverse events. Pericarditis was not reported due to its ordinary occurrence after epicardial procedures. The most common complication was right ventricular puncture (8.7%). Procedure-related mortality was rare (0.7%).
Conclusions: We report the pooled literature rate of complications following percutaneous epicardial VT mapping or ablation. These results can be used in a shared decision making process by physicians for a discussion with patients about the overall risks of percutaneous epicardial VT procedures.
