Intramural Coronary Artery

Intramural coronary arteries in patients with d-transposition of the great arteries (d-TGA) usually arise from the opposite sinus of Valsalva and traverse horizontally across the posterior/facing commissure before emerging externally from the appropriate sinus of Valsalva. Failure to make appropriate technical modifications during coronary transfer can result in an important risk of posttransfer ischemia. We report a case with an unusual course of an intramural left anterior descending (LAD) coronary artery in a patient with d-TGA, with origin at the mid ascending aorta and a vertical intramural course, increasing the susceptibility to injury during an arterial switch operation (ASO).

The arterial switch operation was performed on a 38-day-old infant with d-transposition of the great arteries and abnormal origin of the left anterior descending and right coronary arteries from a non-facing sinus. A vertical aortic tube flap was established to lengthen the abnormally originating coronary arteries, by transecting part of the ascending aorta 2 cm above the coronary orifices. Both coronary arteries were transferred to the neoaortic root in a single extended tube.

Abstract OBJECTIVES Late complications of arterial switch operations (ASO) for transposition of the great arteries, such as neo-pulmonary artery (PA) stenosis and/or neoaortic regurgitation, have been reported. We developed an alternative reconstruction method called the longitudinal extension (LE) method to prevent PA bifurcation stenosis (PABS). METHODS We identified 48 patients diagnosed with transposition of the great arteries and performed ASO using the Lecompte manoeuvre for neo-PA reconstruction. In 9 consecutive patients (from 2014), the LE method was performed (LE). Before 2014, conventional techniques were performed in 39 patients (C). The median body weight and age in the LE and C groups were 3.0 and 3.1 kg and 12 and 26 days, respectively. In the LE group, 1 patient underwent bilateral PA banding before ASO. In C, PA banding and arch repair were performed in 1 patient each. Patients who received concomitant procedures were included. RESULTS The median follow-up in LE and C groups was 1.9 and 10.1 years, respectively. Early mortality/late death was not found in group LE and in 1 patient in group C. Only 1 case required ascending aorta sliding plasty in LE, and 8 patients needed PA augmentation for PABS in C. The median velocity of right/left PA was measured as 1.6/1.9 m/s in LE and 2.1/2.3 m/s in C, so it showed a lower value in LE. CONCLUSIONS Excellent mid-term results were obtained with the LE method. It was considered a useful procedure in preventing PABS, which is a primary late complication of ASO. Further follow-up and investigations are needed.

Purpose: Numerous attempts have been made to extend the boundaries of arterial switch operation (ASO) in children presenting late with transposition of great arteries with intact ventricular septum (TGA/IVS) and regressed left ventricle (rLV). Many children tolerate the delayed ASO uneventfully, whereas others need mechanical circulatory support (MCS) to sustain the systemic circulation while the left ventricle undergoes retraining. Description: In this article, we describe six consecutive children with TGA/IVS and rLV who underwent primary ASO. Results: Three were managed medically, while three required MCS in the form of Centrimag left ventricular assist device (LVAD). All patients survived the operation and were discharged home in a stable condition. Conclusions: Primary ASO can be safely performed in children with TGA/IVS and rLV, provided the center has MCS options. Supporting the rLV with LVAD is feasible and can be achieved safely.
