Background: The arterial switch operation [ASO] is the surgical procedure of choice for correction of the TGA. This is one of the most complex cardiac surgeries, with coronary artery transfer being the most important factor determining the success of the surgery. Objectives: This study aims to investigate the outcomes of ASO operated by a single surgeon and assess the accuracy of echocardiography in identifying the coronary artery pattern before the ASO, this may lead to a better familiarization with the ASO. Methods: A retrospective study was conducted by operative and postoperative case note review of 125 patients from March 2015 to 2018. We assessed the outcomes of the arterial switch operation. Concomitant defects as atrial septal defects, patent ductus arteriosus and small ventricular septal defects were defined as the simple TGA and other defects were defined as the complex TGA. Coronary artery pattern determination by echocardiography prior to the surgery and during the operation was investigated, as well. 30-day mortality, post-operative neurologic complications, cardiac anatomic complications, arrhythmia, plasma lactate level and cardiopulmonary bypass time [CPB time] during the surgery were recorded. Results: The mean age and weight of the patients were 29.09 (1 - 180) days and 3506.48 (2400 - 9700) grams. Most of the patients (64%) were male. 105 (84%) of the patients had simple and 20 (16%) had complex TGA. Unusual coronary pattern during echocardiography was observed in 17 (13.6%) subjects and unusual coronary pattern during the operation was observed in 7 (5.6%) patients. The incidence of the major anatomical lesions was not significant. 20 (16%) had neurologic complications, including seizure in 14 (11.2%) patients, brain hemorrhage was found in 5 (4%) patients, as well as chorea and wrist drop in the remaining patients. Post-operative arrhythmia was observed in 16 (12.8%) patients. The mortality rate was 4% (5 patients). The CPB time was 202.73 ± 36.99 minutes. Conclusions: Our post-operative results of the ASO indicate excellent results. This signifies high experience and knowledge regarding this surgery.

AbstractWe report the case of a child with severe and atypical stenosis of the left main coronary artery, which occurred late after arterial switch operation for transposition of the great arteries. Cardiac computed tomography accurately defined the lesion, showing the presence of post-stenotic dilation, guided the surgical approach and assessed coronary patency after revascularisation surgery.

Can we predict potentially dangerous coronary patterns in patients with transposition of the great arteries after an arterial switch operation?

AbstractIntroduction:Coronary artery complications are the main reason for early mortality after an arterial switch operation. Late complications are relatively rare, and there is no consensus regarding the need or indications for routine follow-up coronary artery evaluations or the best first-line assessment modality. The aim of this study was to present the long-term post-operative frequency of coronary abnormalities in asymptomatic patients with transposition of the great arteries discovered by coronary CT angiography and potential “red flags” revealed by other examinations.Patients and methods:A group of 50 consecutive asymptomatic patients who underwent routine long-term coronary artery evaluation after an arterial switch operation according to our institutional protocol were qualified for this study. This routine in-hospital visit included a detailed medical interview, electrocardiography, echocardiography, Holter electrocardiography examinations, and laboratory and cardiopulmonary exercise tests. Patients who showed significant abnormalities were qualified for perfusion scintigraphy.Results:Unfavourable coronary abnormalities were detected in 30 patients (60%) and included ostial stenosis, muscular bridge, coronary fistula, interarterial course, proximal kinking, high ellipticity index, proximal acute angulation (<30 degree) of the left coronary artery, and proximal acute angulation of the right coronary artery. These features could not be predicted based on the medical interviews, surgical reports, or non-invasive screening test results.Conclusion:Complex coronary configurations with potentially dangerous coronary features are common in patients with transposition after an arterial switch operation. Such high-risk patients cannot be identified indirectly, and coronary CT angiography provides accurate information that is useful for post-operative management.

AbstractA case of left main coronary artery stenosis is presented in a boy late after an arterial switch operation, with significant ischaemia during exercise with good collateralisation through the right coronary artery. The problem was successfully managed with minimally invasive off-pump coronary artery bypass through median re-sternotomy.
