tachycardia: a case series

Aims Ventricular tachycardia (VT) ablation for ventricular arrhythmias is a validated approach, typically performed endocar-dially, or combined with an epicardial approach if endocardial ablation failed or in case of non-ischaemic cardiomyopathy. We report our experience with epicardial only procedure in a subset of patients with incessant VT or VT storm. Methods and results This was a single centre retrospective study. Between 2011 and 2014, all patients referred for VT ablation were reviewed atCHU Bordeaux.All patientswith an epicardial only (anterior percutaneous approach)mapping and ablation procedure were included. In total, 296 patients underwent a VTablation and 4 (all male, 70+ 7 years, 27+11 % left ventricular ejec-tion fraction) of them underwent an epicardial only procedure: two ischaemic patients had an endocardial left ventricular thrombus and incessant VT. One patient post-myocarditis had a failed a previous endocardial procedure without local abnormal ventricular activity (LAVA). The fourth patient had a dilatedcardiomyopathy and acomplicated epicardial punc-ture followed by mild continuous bleeding (200 mL) precluding anticoagulation associated with left ventricular endocar
