Abstract:
Direction of blood flow and peak velocity measurement were made in the four cardiac valve and ascending aorta from 87 normal Korean adults (42 men and 45 women, age range 20-63 years) with CW Doppler echocardiography. Measurments of the peak velocities of mitral valve, tricuspid valve and aortic valve (ascending aorta) completed in the apical window using 2.0MHz Pedof transducer. The measurement of pulmonary flow completed in the parasternal view. Also aortic velocity data obtained from suprasternum (70/87), subcostal area (48/87) and right sternal border(41/87). Aortic flow velocity was highest (121+/-11.7 cm/xec), mitral flow velocity was 86.4+/-12.2 cm/sec, pulmonic flow was 85+/-13.3cm/sec, where as tricuspid was lowest (64.8+/-11.2cm/sec). The velocities of aorta obtained from apex (106.9+/-15cm/sec) and suprasternum (113.1+/-18.9cm/sec) were greater than other sites. These normal Doppler data provide a useful information for evaluating flow velocity pattern in patient with various heart disease.
