# A case of hypertrophic cardiomyopathy with previous aortic valve replacement

## TL;DR

A 45-year-old patient with heart disease was successfully treated with a new minimally invasive procedure after a prior heart surgery.

## Contribution

The paper introduces and demonstrates the safety and efficacy of percutaneous intra-myocardial septal radiofrequency ablation in treating HOCM.

## Key findings

- The patient showed improved symptoms and no obstruction or arrhythmia one month post-surgery.
- Echocardiography revealed enlarged left atria, thickened septum, and stenosis before treatment.
- PIMSRA was safely applied and resulted in significant clinical improvement.

## Abstract

We describe a 45-year-old patient who was diagnosed with hypertrophic obstructive cardiomyopathy (HOCM) after the aortic valve replacement surgery. Enlarged left atria, thickened ventricular septum, left ventricular outflow tract stenosis, moderate mitral regurgitation and mild tricuspid regurgitation in the echocardiography were found. We offered the patient the new minimally invasive treatment modality: percutaneous intra-myocardial septal radiofrequency ablation (PIMSRA). We demonstrate the safety and efficacy with pictures. One month after surgery, the patient recovered well with improved symptoms of chest tightness, and no LVOT obstruction or arrhythmia.
