Apical hypertrophic cardiomyopathy associated with life-threatening paroxysmal atrial flutter with a slow ventricular response: a case report

Apical Hypertrophic Cardiomyopathy: A Case Report

Apical hypertrophic cardiomyopathy (ApHCM) is a rare variant of hypertrophic cardiomyopathy, characterized by a spade-like left ventricular cavity. A 58-year-old African-American female with past medical history of hypertension presented for evaluation of recurrent exertional chest tightness, palpitations and headache. Prior workup including multiple stress tests and angiogram was non-conclusive. Electrocardiogram (EKG) showed characteristic marked T-waves inversions in inferior leads and left ventriculography revealed left ventricle apical hypertrophy with spade like left ventricular cavity that was typical of Yamaguchi syndrome. This case highlights the rare incidence of the disease among African American as well as the challenging diagnostic and presentation features of the disease.

Hypertrophic cardiomyopathy masquerading as infiltrative restrictive cardiomyopathy and refractory congestive failure-resolution with catheter ablation of atrial flutter – A case report

We report a case of a young male presenting as Restrictive cardiomyopathy, refractory heart failure and syncope due to typical right atrial flutter complicating hypertrophic cardiomyopathy.

Successful catheter ablation of the flutter promptly ameliorated the congestive failure with resolution of restrictive physiology.
