Surgical Repair in Case of an Elderly Tetralogy of Fallot / 日本心臓血管外科学会雑誌

ABSTRACT

A 62-year-old woman with the tetralogy of Fallot (TOF) diagnosed at 24 years of age, was admitted with fever and dyspnea. She also had cyanosis and heart failure and was categorized as New York Heart Association (NYHA) functional class IV. Echocardiography showed TOF with a-grade III tricuspid valve regurgitation. Cardiac catheterization revealed major aorto-pulmonary collateral arteries (MAPCAs) for the left upper pulmonary circulation. After coil embolization of MAPCAs to reduce abnormal intracardiac return as well as postoperative left ventricular volume overload, the patient underwent total surgical correction (i.e., right ventricular outflow tract reconstruction using Medtronic FreeStyle Valve and transannular patch, ventricular septal defect closure, and tricuspid annuloplasty). Postoperatively, the patient had a satisfactory course during the 10-year follow-up period with a grade-I NYHA classification. In conclusion, intracardiac repair of TOF in case over 60 years of age can be performed safely by preoperative MAPCAs embolization and subsequent TOF repair with a strategy to abolish pulmonary and tricuspid valve regurgitation.
