Suicide left ventricle triggered by accelerated junctional rhythm after transcatheter aortic valve implantation: a case report of rhythm-dependent dynamic left ventricular outflow tract obstruction.

ABSTRACT:

Background

Suicide left ventricle (LV) is a rare, potentially fatal complication after transcatheter aortic valve implantation (TAVI). It is typically caused by dynamic left ventricular outflow tract obstruction (LVOTO) following abrupt afterload reduction. Accelerated junctional rhythm (AJR) is an uncommon peri-procedural arrhythmia, and its role in precipitating suicide LV has not been reported.

Case summary

An 87-year-old woman with extremely severe aortic stenosis was admitted for transfemoral TAVI. Concentric LV hypertrophy with a sigmoid septum and preserved systolic function was observed on baseline transthoracic echocardiography. She developed profound hypotension immediately after valve deployment. Transoesophageal echocardiography (TOE) revealed severe LVOTO and ma
