Abstract

Hypertrophic cardiomyopathy (HCM) is a genetically determined heart muscle disease; characterized by left ventricular hypertrophy (LVH). Spiral HCM is described as having a counterclockwise rotation pattern of hypertrophy along with variable degrees of fibrosis. A 34-year-old female presented with symptoms suggestive of heart failure. Echocardiography showed concentric LVH with normal contractility. Cardiac MRI showed asymmetric septal hypertrophy with mid-cavity obliteration and a spiral pattern of variably increasing wall thickness. Late gadolinium enhancement (LGE) demonstrated several areas of abnormal postgadolinium uptake. We report a case of spiral HCM. We should consider cardiovascular magnetic resonance (CMR) as the reference standard for diagnosing HCM.
