Myocardial Calcification With A Latent Risk Of Congestive Heart Failure In A Patient With Apical Hypertrophic Cardiomyopathy

Myocardial calcification is rare. An 88-year-old man who had previously been diagnosed with apical hypertrophic cardiomyopathy exhibited left ventricular asynergy on echocardiography before undergoing cholecystectomy. Computed tomography revealed severe calcification in the apical region of the left ventricular myocardium, although the coronary arteries were intact and the hemodynamics on right heart catheterization were normal. The cause of the left ventricular asynergy appeared to be myocardial calcification, thought to be the result of rheumatic fever based on the patient's past history. Stress echocardiography showed a latent risk for the development of heart failure due to the distensibility of the calcified left ventricular myocardium.
