The study was carried out to assess some main echocardiographic finding and to evaluated changes of several peri-operative echo-parameters in patients with total anomalous pulmonary venqus return (TAPVR). Analysed 34 operated TAPVR cases at NHP, Echocardiography classification showed that supra-cardiac type account for 52.9 percent, cardiac type 44.1 percent and infra-cardiac type 3,.. Some suggested ultrasound sign were right heart dilatation, no pulmonary venous flow directed to left atrium, right to left shunting at atrial level or dilated systemic pulmonary venous and/or enlarged. coronary sinus. Definite diagn?sis was made by combination TM, 20 and Doppler technique. Perioperative comparison showed that 1 to 7 days after operation, right ventricular diameter decreased, pulmonary artery pressure and right ventricular - pulmonary valve PG max decreased significantly.
