Abstract
Dilated cardiomyopathy (DCM) is defined echocardiographic analysis by a dilated left ventricle with globally reduced systolic function. Echocardiographic investigation of mitral and tricuspid regurgitation was made in patients with different stages of DCM. The purpose of this study was evaluated the grade of valvula regurgitation by echocardiographic analysis in 190 patients with DCM. The mean left ventricular end systolic dimension, mean left ventricular end diastolic dimension, and percent of mean left ventricular ejection fraction, were significantly (P <0.05) worse in nonsurvivors than insurvivors after 5 year observation. Although the grade of mitral and tricuspid regurgitation were significantly worse in nonsurvivors than in survivors, the regurgitation of aortic or pulmonary valuewere not different between the two groups. The regurgitation of mitral and tricuspid valve appears to be an important prognostic indicator for patients with DCM.
