Diffuse hypertrophic obstructive cardiomyopathy complicated by apical ventricular aneurysm and excessive left ventricular trabeculation: a case report.

This article reports a rare case of diffuse hypertrophic obstructive cardiomyopathy complicated with left ventricular apical aneurysm and excessive trabeculation. Genetic testing of the patient revealed a heterozygous variant of the MYBPC3 gene (c.3343G> A: p.Val1115Ile). Despite optimal medical therapy and implantable cardioverter-defibrillator (ICD) implantation, the patient developed progressive cardiac dysfunction and recurrent ICD shocks. We discuss the clinical course, genetic findings, and imaging features of this case.
