Incidental Discovery of Dystrophic Myocardial Calcification.

Background: Myocardial calcification is a rare condition, often discovered incidentally during cardiac evaluations. It can result from myocardial necrosis or systemic metabolic disturbances.

Methods: A 58-year-old woman presented with palpitations and diarrhea. Atrial fibrillation with spontaneous conversion to sinus rhythm was noted, along with a left ventricular mass identified on echocardiogram and confirmed via computed tomography as dystrophic calcification. Management included rehydration, antiarrhythmic therapy, and anticoagulation. The calcification, linked to previous myocardial infarctions, was considered an incidental finding, with no significant systolic dysfunction.

Conclusions: This case highlights the rare occurrence of dystrophic myocardial calcification following necrosis, a condition that can remain asymptomatic but may predispose patients to arrhythmias or heart failure. Early detection and thorough evaluation, including imaging, are crucial to guide management and surveillance.
