The indication was primary prevention in 86 patients (66%), and 22 patients (17%) had a previous transvenous device. Seventy\u2010seven patients (60%) had heart failure, and the median left ventricular ejection fraction was 36% (29%\u201360%). The procedure was performed under general anaesthesia in 124 patients (97%), and the median procedure time was 105 min (interquartile range (IQR) 90\u2013120). During a median follow\u2010up of 4.7\u2009years (IQR 3.8\u20135.8), 15 patients (12%) died, none of which were due to sudden death or device\u2010related complications. Inappropriate shocks occurred in 17 patients (13.3%), predominantly due to T\u2010wave oversensing (4.7%) and supraventricular arrhythmias (4.7%), and 15 patients (11.7%) received appropriate shocks. During the follow\u2010up period, the S\u2010ICD system was revised to TV\u2010ICD in 10 patients (8%), and 24 patients (19%) required S\u2010ICD generator change. Four patients (3%) underwent surgical intervention due to lead (two) or pocket\u2010related (two) complications, and two patients (1.5%) developed pocket infection without systemic
