It is usually silent in early stages and manifests in adults with a suspicion of typical ECG changes of giant T wave inversion in left precordial leads. Transthoracic echocardiography is the mainstay of non-invasive diagnosis and provides a heterogeneous appearance of its morphological features with a spade-shaped LV (left ventricular) cavity. Background of this case study describes the apical HCM in an asymptomatic male at the age of 54 years old and also predicts the mixed and mid-ventricular forms of left ventricular HCM at this region of Thoothukudi in India.展开更多

It contributes 25% of cases of hypertrophic cardiomyopathy in Japan but only 1% to 2% in the non-Japanese population. It may occasionally present in the elderly and classically involve the apex of the left ventricle. An isolated apical right ventricular involvement had been detected in an elderly female by transthoracic two-dimensional echocardiographic imaging.展开更多
