# Apical Hypertrophic Cardiomyopathy With a Sub-aortic Membrane: A Case Report

## TL;DR

This case report describes a rare combination of hypertrophic cardiomyopathy and a subaortic membrane in a 52-year-old man, highlighting diagnostic and treatment challenges.

## Contribution

The novelty lies in presenting a rare coexistence of HOCM and subaortic membrane, emphasizing the need for thorough diagnostic evaluation.

## Key findings

- The patient exhibited both dynamic and fixed left ventricular outflow tract obstructions.
- Comprehensive diagnostic workup was crucial for managing the complex cardiac abnormalities.

## Abstract

Hypertrophic obstructive cardiomyopathy (HOCM) and subaortic membrane (SAS) are distinct cardiac conditions, but their coexistence presents complex diagnostic challenges. We report the case of a 52-year-old male with HOCM and a concurrent subaortic membrane, highlighting the intricacies of diagnosis and management. The patient's presentation included symptoms of dyspnea and chest tightness, and diagnostic evaluations revealed a unique combination of dynamic left ventricular outflow tract (LVOT) obstruction from HOCM and fixed obstruction from the subaortic membrane. This case emphasizes the importance of a comprehensive diagnostic workup to guide appropriate treatment decisions when managing multiple cardiac abnormalities.
