OBJECTIVE: To discuss early efficacy of the cardiac patient with giant left ventricle underwent valve replacement.

PATIENTS AND METHODS: Fifty-five patients, who are suffering cardiac valve disease with giant left ventricle, underwent valve replacement. Among them, sixteen patients underwent aortic valve replacement; thirty patients underwent mitral valve replacement; nine patients underwent double valve replacement. All of them use mechanical heart valve.

RESULTS: The number of early death after operation was five. Two patients died of malignant arrhythmia; two died of intractable low cardiac output syndrome; the last one’s mechanical valve lost its ability to function after operation and died of respiration-circulation failure after an emergency operation. The death rate was 9%. The remaining 55 patients were cured and their cardiac function was significantly improved.

CONCLUSIONS: The definite effective myocardial protection and perfect and detailed preoperative treatment can reduce the possibility of operative complications and death rate of this kind of patients.
