Risk factors associated with mortality and interventions in 472 neonates with interrupted aortic arch: A Congenital Heart Surgeons Society study

Abstract

Anatomic features affect mortality and initial left ventricular outflow tract procedures, whereas characteristics of the arch repair affect arch reintervention.

Outcomes of Aortopulmonary Window Repair in Children: 33 Years of Experience

“…They reported operative mortality for simple APW as 0% (0 of 11 patients) and for complex APW, 12.5% (3 of 24 patients) [5]. Similarly, Tkebuchava and associates [8] described their experience with repair of APW in 11 patients between 1971 and 1993, with operative mortality for simple APW of 0% (0 of 5 patients) and 16.7% (1 of 6 patients). The single death in this study was of a patient with concomitant IAA [8].…”

“…The first was for an aortic arch stenosis in a patient with APW and type B IAA at 13 years after initial surgery. Type B IAA is a known risk factor for reintervention [16]. The second was for a pulmonary valve stenosis at 9 years after repair in a patient with APW and TOF.…”

Management strategies for interrupted aortic arch with associated anomalies

“…IAA is defined as either a complete discontinuity or a nonpatent fibrous strand in the transverse arch or aortic isthmus [12,13]. The types of IAA were described by Celoria and Patten [12,14].…”

“…Most patients have only an isolated VSD [13] but IAA can be associated with a variety of complex cardiovascular anomalies [1,7]. A spectrum of left ventricular outflow tract obstructive (LVOTO) lesions, particularly subaortic stenosis (SAS), is also common [1,4,5,7,15].…”

Creating an Arc-Shaped Aorta: Use of the Subclavian Artery for Interrupted Aortic Arch Repair

“…D irect anastomosis with or without a patch, and interposition of a vascular prosthesis are the most commonly used techniques to repair an interrupted aortic arch (IAA) [1,2]. The use of a subclavian artery is known for aortic coarctation repair [3,4].…”
