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

Hypertrophic obstructive cardiomyopathy is an inheritable cardiac disease that typically manifests with an increased left ventricular outflow tract gradient. In most cases, basal septal hypertrophy and systolic anterior motion of the anterior mitral valve leaflet are the key components of the 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 an alternative therapy for patients who decline to have surgery or who are not suited to a surgical intervention. A new septal reduction 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.
