Abstract
Percutaneous pericardial access EpiAcc assists ventricular tachycardia/premature ventricular complex VT/PVC ablation by permitting epicardial mapping and ablation outside the vicinity of the coronary venous system We sought to determine whether expanding indications and growing operator experience have led to increased rates of EpiAccThere were 758 patients undergoing 880 VT/PVC ablation procedures average 95 patients per year 110 procedures per year during the study period EpiAcc for ablation was utilized in 170 patients 181 procedures The average age at the time of EpiAcc was 55 ± 16 years and 129 760 patients were male The rate of EpiAcc was 229 in males and 154 in females P = 0008 The absolute number of EpiAcc procedures increased from 2007 6 procedures to 2014 27 procedures Similarly the proportion of patients undergoing EpiAcc increased from 86 of procedures in 2007 to 245 in 2014 P 00001 While EpiAcc use became more frequent the rate of epicardial ablation among those who underwent EpiAcc remained stable approximately 70 Percutaneous pericardial access has been used with increasing frequency as part of VT/PVC ablations without an increase in the rate of epicardial ablation This growing utilization may lay the foundation for novel epicardial strategies as new technologies emerge The frequency of percutaneous pericardial access in VT/PVC ablation appears to be greater in males reasons for which are undefinedConcept/design was done by AMK and PAF Data analysis/interpretation was performed by AMK and DOH Drafting of the article was done by AMK Critical revision of the article was done by AMK AMS SKM CJM PAN SJA and PAF AMK AMS SKM CJM DOH PAN LF TMM DLP SJA and PAF approved the article Statistics were from DOH Funding was secured by the Mayo Clinic Data collection was done by AMK and AMS
