ABSTRACT
Two-dimensional Doppler echocardiographic velocity profiles of four cardiac valves in a group of 85 infants and children with left to right shunt lesions(VSD, ASD and PDA) are presented. Velocities were obtained before operation and 10 days afterward. The results were as follows ; 1) VSD(type 2) Peak velocities of mitral valve were significantly decreased when compared preop. with postop. echocardiogram(n=37, preop 132+/-24, postop 98+/-16 cm/sec, p0.05). Aortic valve velocities showed no significant changes (n=10, perop 134+/-23, postop 121+/-25cm/sec, p>0.05). Peak velocities of pulmonic valve were significantly decreased(n=28, perop 138+/-37, postop 107+/-27cm/sec, p<0.005). This study demonstrates that Doppler echocardiographic assessment of velovity changes are correlated with known hemodynamic data and also will be a good index in the evaluation of operation.
