[Valve replacement in patients with huge heart].

In general, valve replacement for patients with big heart (cardiac-thoracic rate greater than 0.80) has been considered a contraindication. Mitral valve replacement was done in 11 patients with a C/T rate of 0.81 to 0.97. In addition, aortic valve replacement was performed in 2 patients and tricuspid valvuloplasty in 5. One patient died from low cardiac output after operation. The heart function of the survivor was improved from III or IV to II degree after operation. We consider that active pre- and postoperative management for preserving myocardial function and preoperative technique are important for the successful treatment of patients with huge heart.
