Abstract:
The association of truncus arteriosus (TA) and an intramural coronary artery is rare. Seven (7) patients had TA and an intramural coronary artery at the Royal Children's Hospital, Melbourne between 1996 and 2018. Four (4) patients underwent concomitant unroofing of their intramural coronary artery. One (1) patient who did not undergo concomitant unroofing had a cardiac arrest on postoperative day 1 and subsequently underwent reoperation for coronary unroofing. Given the potential for serious complications, patients with TA and an intramural coronary artery may benefit from coronary unroofing with creation of a generous neo-ostium.
