Is subcutaneous fat tissue embolization effective and safe as a septal reduction technique in a patient with hypertrophic obstructive cardiomyopathy

Abstract

Hypertrophic obstructive cardiomyopathy isan inheritable cardiac disease that typically manifests withan increased left ventricular outflow tract gradient. In mostcases, basal septal hypertrophy and systolic anterior motionof the anterior mitral valve leaflet are the key components ofthe left ventricular outflow tract obstruction. The goal of septal reduction therapy, a widely accepted treatment modality,is to remove this obstruction. Although myectomy is a wellestablished and effective surgical technique for septal reduction therapy, transcoronary alcohol septal ablation is analternative therapy for patients who decline to have surgeryor who are not suited to a surgical intervention. A new septalreduction method has also been described in the literature.This case report describes the successful treatment of hypertrophic obstructive cardiomyopathy in a 57-year-old female using the new septal reduction technique.
