The impact of a bicuspid pulmonary valve in the aortic position after arterial switch for transposition of the great arteries on neoaortic root dimension and function: a propensity score matched analysis.

Objectives: This study investigated the effect of a bicuspid pulmonary valve on neoaortic root morphology, function, and the clinical outcomes of early survivors after the arterial switch operation using propensity score matching.

Methods: From 1997 to 2018, a total of 442 patients underwent the arterial switch operation for transposition of the great arteries. After exclusion of patients who underwent a staged repair, were repaired beyond 1 year of age, died before discharge and who lacked echocardiographic data at discharge, propensity score matching was used for analysis.

Surgical treatment of tetralogy of Fallot in symptomatic neonates and young infants.

Objectives: Optimal management of tetralogy of Fallot in symptomatic neonates and young infants remains controversial.

Methods: A retrospective review of 53 patients (26 male) with symptomatic tetralogy of Fallot who underwent primary repair (group 1, n = 22) or initial palliation (group 2, n = 31) within 2 months (60 days) after birth between 2005 and 2018 was performed. Subsequent repairs were performed in 29 patients at postpalliation 7.
