[Two successful cases of total extracardiac right heart bypass]

We reported two successful cases of extracardiac total right heart bypass using 20 mm EPTFE conduit (modified total cavopulmonary connection). They were seven-year-old boy and nine-year-old girl. Both patients had complex heart disease including cyanosis, atrioventricular discordance. We selected this technique instead of modified Fontan or conventional total cavopulmonary connection because of safeness and easiness of surgery and the hemodynamic benefits. They don't have any restriction for their life postoperatively. We propose this technique as an alternative surgical option in candidates for a Fontan procedure or conventional total cavopulmonary connection.
