Research Abstract

Early survival after Fontan procedure has improved dramatically for the development of perioperative surgical treatment and strategy based on each surgeon's experience and scientific data. Despite of these improvement, there are still concerns about long-term complications, i.e. pulmonary arteriovenous malformation and thrombus formation in the conduit, which can less the quality of life after surgery. We simulated the optimal design of procedures with computational fluid dynamics to gain the better quality of survival and the optimal anastomosis was developed both in Fontan and Glenn procedure. This technique could be applied to designing of the different type of pediatric cardiac surgery, which is expected to lead the better quality of life after surgery.
