概要 Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a slow-developing cardiomyopathy characterized by ventricular arrhythmias and fibrofatty replacement of the right ventricular (RV) myocardium. Its clinical diagnosis is challenging because of its variable clinical presentation and low genetic penetrance. We describe the case of a 67-year-old man who was diagnosed as having ARVC/D with a desmoplakin mutation that appeared after occlusion of an atrial septal defect (ASD). He underwent patch closure surgery for ASD at the age of 54 years. Four years later, he underwent catheter ablation for multifocal atrial tachycardias. Because of pre-syncope and inducible sustained monomorphic ventricular tachycardia, an implantable cardioverter defibrillator was implanted. When he was admitted for worsening heart failure at the age of 61 years, the desmoplakin mutation was detected with progressive left ventricular (LV) dysfunction. Subsequently, he was diagnosed as having ARVC/D with RV dysfunction. At cardiac autopsy, characteristics of ARVC/D, including dilatation, fibrofatty changes in the right ventricle, and diffuse fibrosis in the left ventricle were detected. Along with the effect of RV dysfunction caused by ASD, the progression of LV dysfunction after ASD closure was also possibly caused by the disease progression of ARVC/D. Physicians should carefully assess the various states of ARVC/D. <Learning objective: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a cardiomyopathy characterized by arrhythmias, fibrofatty replacement of the right ventricular (RV) myocardium, and slow progression to more diffuse ventricular dysfunction. This case involved an atrial septal defect (ASD) that promoted the RV failure and was complicated with delayed progression of ARVC/D after ASD closure. The present case suggests that physicians need to carefully assess the various states of ARVC/D.>.
