A 71-year-old woman underwent VVI pacemaker implantation for complete atrioventricular block 38 years ago at the cardiovascular department of another hospital. In the course of observation, she developed atrial fibrillation. One year ago, she was admitted to hospital for aggravated congestive heart failure and was subsequently treated by a cardiovascular practitioner. She had persistent shortness of breath and lower leg edema, which were treated with increasing doses of oral diuretics. Due to poor treatment outcomes, she was referred to our hospital. Her echocardiography results suggested severe tricuspid regurgitation (TR) and moderate mitral regurgitation. She was also found to have impaired renal function and liver cirrhosis (Stage A of the Child classification), and was admitted. In addition, she had undernutrition with suspected cardiac cachexia. She was first treated by inotrope infusion and central venous hyperalimentation before tricuspid annuloplasty and mitral valvuloplasty were performed. Even though her postoperative management was complicated, she was discharged from our hospital. The conservative treatment with the increased dose of the diuretic for TR-associated right heart failure was prolonged in this patient, leading to severe right heart failure and aggravation of impaired renal function or congestive liver-associated hepatic disorders. Eventually, the patient required operative intervention; however, postoperative management is usually complex, and the operation result may be poor in such patients. We suggest that, from the time when right heart failure can be managed with relatively small doses of diuretics, surgeons should be involved in the care of patients with severe TR who do not require left heart valvular surgery, and should discuss the necessity of surgery earlier than the relevant guidelines suggest, depending on the patient's condition.
