Although atrial fibrillation ( AF ) often exists in patients with hypertrophic obstructive cardiomyopathy ( HOCM ), combination of tricuspid regurgitation ( TR ) and AF after implantation of pacemaker/implantable cardioverter defibrillator ( ICD ) lead and its optimal management have not been well discussed in this population. Herein, we present a patient with HOCM who subsequently died due to severe heart failure and deterioration of TR following ICD lead placement with AF . Autopsy findings demonstrated that ICD leads were entrapped by anomaly structure in the right atrium and ventricle, which might affect deterioration of TR .
