Application of color Doppler ultrasonography in differentiating restrictive cardiomyopathy and constrictive pericartiditis / 中华超声影像学杂志

ABSTRACT

Objective To assess the clinical diagnostic value of color Doppler ultrasogography in restrictive cardiomyopathy and constrictive pericarditis.Methods Observing mitral valvular, tricuspid valvular, pulmonary and hepatic venous flow in 16 cases of restrictive cardiomyopathy (RCM) and 20 cases of constrictive pericardities (CP), getting the spectrum results of above, analysis was made on the spectrum change accompanied with respiration. Twenty cases of normal served as control. Results Both during inspiration and expiration, the maximal peak velocity and time (E M and E T) of mitral and tricuspid valvular in group constrictive pericardities had statistical difference compared with normal group (P
