Truncus arteriosus

Truncus arteriosus (TA) is a rare congenital cardiovascular anomaly characterized by a single arterial trunk arising from the heart by means of a single semilunar valve (<I>i.e.</I> truncal valve). Pulmonary arteries originate from the common arterial trunk distal to the coronary arteries and proximal to the first brachiocephalic branch of the aortic arch. TA typically overrides a large outlet ventricular septal defect (VSD). The intracardiac anatomy usually displays situs solitus and atrioventricular (AV) concordance.

	Anaphylaxis to Surgiflo During Posterior Spinal Fusion in an Adolescent Status Post Truncus Arteriosus Repair: A Case Report.
	Manrique Espinel AM, Feldman JM, Nelson S, Smaliak T, Flynn JM, Nicolson SC. A A Pract. 2018;10(6):129-132.
	We describe the case of an adolescent with a history of repaired truncus arteriosus undergoing posterior spinal fusion who developed sudden and profound hypotension that was ultimately confirmed to be an anaphylactic reaction to Surgiflo.
