Twenty\u2010nine cavotricuspid isthmus (CTI) and 29 mitral valve isthmus (MVI) ablations were performed. There was no relationship between center case number and procedure or fluoroscopy time for atrial cases suggesting no evident learning curve with this technology. One stroke occurred acutely, one patient had ST elevation during CTI ablation without sequelae and one had tamponade. Acute success was excellent with all ablations successful, apart from failure to block one MVI. Short\u2010term success rates (median follow\u2010up 5[3] months) were 74% for atrial ablations and 63% for ventricular ablations (45% for ventricular tachycardia, 100% for ventricular ectopic).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This multicenter cohort suggests the versatility of this focal PFA platform. The use of conventional mapping and ablation equipment abrogates any learning curve. The short\u2010term success rates are encouraging for ventricular ectopic and atrial ablation, but the waveform may need optimizing for ventricular tachycardia ablation. Randomized trials are needed to investigate further the success and complication rates with this technology.<\/jats:p>\n
