Late onset radiation-induced constrictive pericarditis and cardiomyopathy after radiotherapy

INTRODUCTION Radiation-induced heart disease (RIHD) is a serious side effect of cancer treatment, including coronary artery disease, valvular cardiac dysfunction, cardiomyopathy, aortopathy, and chronic constrictive pericarditis. Herein, this case we present was diagnosed as radiation-induced constrictive pericarditis and cardiomyopathy by means of cardiac magnetic resonance (CMR) and transthoracic echocardiogram, finally confirmed by pathology after performing heart transplant operation. CONCLUSIONS This case supports a notion that RIHD often causes multiple heart impairment and CMR is helpful to diagnose cardiomyopathy after radiation.
