Apical hypertrophic cardiomyopathy should be considered in asymptomatic patients presenting with classical giant T wave inversions on ECG, with echocardiography being the mainstay for diagnosis.
Apical HCM description supports benign prognosis in Japanese adults; leaves open need for prospective validation in diverse cohorts.
Apical Hypertrophic cardiomyopathy is a rare variant of HCM and has a prevalence of around ~ 15 % among HCM patients. As compared to other variants, it has a relatively benign prognosis. Predominantly prevalent in the Japanese population; it is characterized by localized hypertrophy of the LV apex as compared to other segments. It is usually silent in early stages and is manifested at an adult stage with typical ECG changes of giant T wave inversions in the precordial leads. Transthoracic echocardiography remains the mainstay of non – invasive diagnosis. We report a case of an asymptomatic elderly male who presented with the classical deep T wave inversion in ECG for which echocardiography revealed the apical variant of hypertrophic cardiomyopathy.
