The intraoperative use of recombinant activated factor VII in arterial switch operations.

Background: The rate of bleeding complications following arterial switch operation is too low to independently justify a prospective randomised study for benefit from recombinant factor VIIa. We aimed to evaluate factor VIIa in a pilot study.

Methods: We performed a retrospective cohort study of patients undergoing arterial switch operation from 2012 to 2017.

Reoperation after isolated subaortic membrane resection.

Background: The resection of a subaortic membrane remains far from a curative operation. We sought to examine factors associated with reoperation and the degree of aortic valve regurgitation as a potential long-term source for reoperation.

Methods: All patients who underwent resection of an isolated subaortic membrane between 1995 and 2018 were included.

Fetal and postnatal echocardiographic imaging of transposition of the great arteries with the aortic valve posterior to the pulmonary valve.

Transposition of the great arteries (TGA) with a posterior aorta is an uncommon but historically important variant of TGA. In this arrangement, the aorta is posterior to the pulmonary valve, maintains fibrous continuity with the mitral valve, and arises from the right ventricle. We present a case of fetal echocardiography demonstrating TGA with a posterior aorta.
