French experience of SICD implantation

GPUR

The subcutaneous ICD prevents complications of transvenous leads. Its implantation needs a defibrillation test. Performing this test increases the time of procedures..

The aim of our study is to describe the experience of subcutaneous ICD of Assitance Publique des Hopitaux de Paris (AP-HP).

In a retrospective cohort we included patients who were involved in subcutaneous ICD treatment at the 5 hospitals of AP-HP from December 2012 to April 2018.Analysis used the Kaplan-Meier method and the Mann-Whitney U test.

162 patients were implanted. 76% of implantations were for secondary prevention before 2017, but only 49% after 2017. 126 (77%) tests were successful at first shock, 14 (8.6%) needed a second shock or more, 9 (5.5%) did not have a test. The shock impedance was significantly higher when the shock was not effective at the first test, 82 ohms CI 95% [68; 112] versus 66 ohms CI 95% [64; 70], p <0.05. 6 patients died (3.7%). Late follow up showed 23 (10%) appropriate shocks and 24 inappropriate shocks (11%) mainly due to T wave oversensing (37.5%).

This is the first french experience of SICD implantation. Success of defibrillation test was lower than expected.
