Micro-coil embolization for transcatheter septal ablation in a hypertrophic obstructive cardiomyopathy patient and an unusual coronary anatomy: a case report.

ABSTRACT:

Background

Transcatheter septal ablation is a minimally invasive therapeutic method for treating symptomatic obstructive hypertrophic cardiomyopathy (HCM). The procedure is an alternative to septal myectomy, and it can be achieved using different modalities. Coronary artery congenital anomalies can coexist with HCM and can add complexity to its treatment.

Case summary

A 65-year-old female presented with angina, reduced exercise tolerance, palpitations, and dizziness. Echocardiography showed eccentric left ventricular hypertrophy with basal septal thickness of 20 mm and left ventricular outflow tract (LVOT) obstruction with maximum gradient of 209 mmHg. Cardiopulmonary exercise stress test showed a decreased oxygen uptake (VO2) of 13.7 ml/min/m2. Medical therapy titrated to m
