ABSTRACT
8kPa, 113 cases of type ASD and VSD with diameter from 0.5 to 2.0 cm were operated upon with open heart technic from June 1995 to June 1999. There was no mortality, no air embolism, except in 4 cases operation was only completed under moderate hyperthermia and cardiac arrest instead due to poor vision of the operating field. 12 cases were complicated by slight hemoglubinuria after 24h of operation, and 1 case by remnant VSD. 95 cases were followed up, and they were in healthy condition. This operative technic is suitable for the repair of secondary ASD, and small or moderate, membranous or para membranous VSD. Its advantage is less myocardial damage, and shorten the duration of cardiac arrest. Air embolism is likely to take place by using this method, but effective method should be taken to prevent it.
