Impingement of the occluder on tricuspid valve

Abstract

3. Comment The most common adverse events after VSD device closure is conduction anomalies (15%) (1, 2). Tricuspid regurgitation is a major consideration in transcatheter closure of VSD (< 2%). The impingement of the occluder on the valve leaflets by interfering with chordae tendineae may cause instant tricuspid regurgitation. Consequently echocardiography and angiography are crucial for confirming the correct deployment of the device (2).
