A successful management of late-presenting transposition with intact septum and severe coarctation of the aorta

Abstract

A 13-week-old baby was referred with dextrocardia, situs inversus, transposition of the great arteries, intact ventricular septum, patent foramen ovale, right aortic arch with severe preductal aortic coarctation and large patent ductus arteriosus. Left ventricular mass index as well as thickness was adequate, 118 g/m2 and 5.9 mm, respectively; thus, a primary arterial switch with aortic coarctation repair was performed. The patient made a full recovery without the need for extracorporeal life support. Adequate left ventricular mass index and thickness in late-presenting transposition of the great arteries with intact ventricular septum might justify primary arterial switch.

Impaired Speckle-Tracking-Derived Left Ventricular Longitudinal Strain Is Associated with Transposition of Great Arteries in Neonates: A Single-Center Study

“…During this period, alongside the physiological decrease in pulmonary arteriolar resistance, the LV mass also begins to decrease (although with a certain degree of reversibility); thus, echocardiographic monitoring with a careful evaluation of the performance of the LV is warranted [6,9]. A reduction in the indexed LV mass below 35 g/m 2 , the age of the newborn over 3 weeks, A 2D "banana-shaped" echo appearance of the LV, the absence of a PDA or LV outflow tract obstruction represent non-invasive indication criteria for performing an arterial switch operation (ASO) in two stages [10].…”
