Multiple Myocardial Clefts on Cardiac Magnetic Resonance Imaging

Abstract

Myocardial clefts are a recently described finding and are increasingly noted with the growing use of cardiac MRI. We describe a patient with multiple myocardial clefts on MRI. A 45-year-old man came for cardiac screening evaluation because of an abnormal ECG. He had undergone occupational health screening 8 years previously and had been noted to have T-wave inversion from V2 to V4. He had not pursued any further investigations. He was asymptomatic, with no history of syncope. Examination results were within normal limits. A 12-lead ECG again showed anterior T-wave inversion, with no associated Q waves (Figure 1). A transthoracic echocardiogram showed mild asymmetrical interventricular septum thickening, measuring 14 mm …
