Abstract

Among tricuspid surgical cases, there has been a histor y of cardiac device implantation and it has been reported that the right ventricular lead leads to tricuspid valve closure failure（TR）. We report a case of severe TR due to shock lead which was detained 13 years ago. At the age of 53, cardiac catheterization was performed to examine palpitations, diagnosed with advanced atrioventricular block and sustained ventricular tachycardia, and an implantable cardioverter defibrillator（ICD: DDD type） was detained. Dyspnea appeared at the age of 65, so diuretic treatment was performed but weight gain, orthopedic respiration appeared, it became emergency hospitalization to the previous doctor, transferred to our hospital for the purpose of examinations for heart failure. The chest X–ray showed an enlargement of the cardiothoracic ratio, which was high as BNP 281 pg/mL by blood test. Echocardiographic examination showed high TR. Tricuspid valve replacement, Shock Reed reconstruction surgery, ICD exclusion surgery were performed, diagnosed as severe TR associated with Shock Reed. We experienced a case of severe TR due to shock lead which we detained 13 years ago.
