Case in brief

A 52-year-old male with no prior medical history was found dead upon arrival at the emergency department. Autopsy revealed significant left ventricular hypertrophy with a thickness of 3 cm and interventricular septum thickness of 2.5 cm. Histopathological analysis showed myocardial disarray and hypertrophy, alongside Grade 2 pulmonary arteriopathy characterized by thickened vascular walls in the lungs, linking HOCM with pulmonary vascular changes.

Diagnostic / clinical pearl

Clinicians should consider the potential for pulmonary arteriopathy in patients with hypertrophic obstructive cardiomyopathy, as it may indicate disease progression and contribute to sudden cardiac events.
