Coronary artery status in adults long after the arterial switch operation (ASO) is unclear. We conducted a systematic review to provide an overview of coronary complications during adulthood and to evaluate the value of routine coronary imaging in adults after ASO, in light of current guidelines. Articles were screened for the inclusion of adult ASO patients and data on coronary complications and findings of coronary imaging were collected. A total of 993 adults were followed with a median available follow-up of only 2.0 years after reaching adulthood. Myocardial ischemia was suspected in 17/192 patients (8.9%). The number of coronary interventions was four (0.4%), and coronary death was reported in four (0.4%) patients. A lack of ischemia-related symptoms cannot be excluded because innervation studies indicated deficient cardiac innervation after ASO, although data is limited. Anatomical high-risk features found by routine coronary computed tomography (cCT) included stenosis (4%), acute angle (40%), kinking (24%) and inter-arterial course (11%). No coronary complications were reported during pregnancy (n = 45), although, remarkably, four (9%) patients developed heart failure. The 2020 European Society of Cardiology (ESC) guidelines state that routine screening for coronary pathologies is questionable. Based on current findings and in line with the 2018 American ACC/AHA guidelines a baseline assessment of the coronary arteries in all ASO adults seems justifiable. Thereafter, an individualized coronary follow-up strategy is advisable at least until significant duration of follow-up is available.

Objectives: To evaluate the outcomes of arterial switch operation (ASO) in a subgroup of patients who had intramural coronary arteries at National Children’s Hospital. Methods: From 2010 to 2016, 304 patients underwent ASO at National Children’s Hospital. In which, eighteen (5.9%) had intramural coronary arteries. These medical records of these patients were collected and retrospectively reviewed. Results: There were 10 male and 8 female in this group of patients. Patients with intramural coronary arteries had transposition of the great arteries (83.3%, n = 15) or Taussig - Bing anomaly (16.7%, n = 3). At the time of surgery, mean age was 69.5 ± 81.5 [11 - 321] days and mean weight was 3.9 ± 1.1 [2.5 - 6.3] kg. Mean bypass time and mean aortic cross - clamped time were 235 ± 90 [168 - 564] minutes and 149 ± 29 [100 - 255] minutes respectively. There were 3 deaths (16.7%): two hospital deaths (at 6 days and 26 days after ASO), one death after discharge (2 months later). One patient lost follow - up. Other 14 patients are in a good health status after discharge and free of re - intervention or reoperation related to the total correction with the mean follow - up time of 68.0 ± 38.5 [2 - 113] months. Conclusions: Intramural coronary arteries remain a rare coronary anatomic variant following ASO. The outcomes of ASO in this subgroup of patients is quite favorable. Long - term follow - up is necessary.

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.

Introduction: Neo-aortic root dilation (ARD) is common after arterial switch operation (ASO) for D-loop transposition of the great arteries (TGA). We sought to compare short and long-term outcomes for bicuspid native pulmonary valve (BNPV) patients to those with normal trileaflet variants (TNPV). Methods: A retrospective cohort of TGA patients undergoing ASO at Boston Children’s Hospital from 1989-2018 was analyzed, matching BNPV patients 1:3 with TNPV patients by year of ASO; those with >mild subpulmonary stenosis or complex TGA were excluded. Categorical and continuous variables were compared using Fisher’s exact and Wilcoxon rank sum tests, respectively. Kaplan-Meier analyses with log-rank test compared groups for time to first reoperation on the neo-aortic valve, first occurrence of ≥moderate neo-aortic regurgitation (AR), and ARD defined as root z-score ≥4. Hazard ratios were estimated based on the Cox proportional hazards model. Results: A total of 83 BNPV patients were matched with 217 TNPV. BNPV patients were more likely to have a VSD (75% vs 44%, p <0.001). Early surgical outcomes including hospital LOS (11 vs 10 days) and 30-day mortality (3.6% vs 2.8%) were similar. During median 10 years follow-up, neo-aortic valve reoperation occurred in 4 BNPV (6%) vs 6 TNPV (3%) patients, with no statistically significant difference in time to reoperation. More BNPV patients had AR at discharge (4.9% vs 0%, p=0.014) and during follow-up (13.4% vs 4.3%, HR 3.9, p=0.004), with shorter time to first occurrence of AR (Figure 1A); this remained significant after adjusting for presence of VSD. Similarly, ARD was more common in BNPV (45% vs 37%, HR 1.64, p=0.02) with shorter time to first occurrence (Figure 1B). Conclusions: While patients with BNPV have similar short-term ASO outcomes, AR and ARD occur more frequently and earlier compared with TNPV patients. Further long-term studies are needed to determine whether this results in greater need for neo-aortic valve reoperation.

Unusual Origin

The arterial switch operation1 has now become the surgical treatment of choice for those patients born with transposition, specifically the combination of concordant atrioventricular and discordant ventriculo-arterial connections. For those working in experienced centres, the operation is now a stable and well-controlled procedure. The gathering of the necessary experience to achieve such control proceeds through two different stages. The first is the familiarity gained during the surgical transfer of the coronary arteries in those patients with the usual anatomic pattern. The second step is gain the expertise so as to cope with the more complex arrangements, in which the major coronary arteries have not only an unusual origin from the aortic sinuses, but also an unexpected epicardial course relative to the arterial pedicle. There can still be a steep learning curve as the surgeon corrects those patients with the more complex arrangements. In this review, we discuss a simplified but uniform technique for surgical transfer that permits relocation of the coronary arteries irrespective of their sinusal origin or their epicardial course. The technique has been used for more than 15 years in Hopital Marie Lannelongue in Paris,2–5 and proved its worth during the initial experience of the Senior Author (FLG) in two new centres, namely the Universitat Krankenhaus Eppendorf, Hamburg, and the Children's Hospital, Denver.

SummaryThe long-term natural progression of cardiac rhythm and the incidence of serious arrhythmias in relation to previous procedures and associated heart defects were studied in a group of 76 patients after an arterial switch operation for complete transposition and compared to a group of 24 patients who had undergone intraatrial corrections (Mustard or Senning operation). Standard and 24-hour ambulatory electrocardiograms were reviewed. Mean follow-up was 7.9 years (range 2-16) after an arterial switch and 15.2 years (range 6-26) following the Mustard or Senning procedures. One patient died after an arterial switch from pulmonary hypertension (age 9.9 years), and three patients died suddenly, presumably from arrhythmias, following atrial redirection procedures (ages 13, 18 and 20 years). Symptomatic arrhythmias were not seen after the arterial switch operation. Three patients required pacemaker implantation after atrial redirection, and a further two required medication to control tachyarrhythmias. Survival analysis of sequential electrocardiograms showed a mean maintenance of sinus rhythm during 12.9 years (95% confidence interval 11.4-14.5) after the arterial switch and 9.0 years (7.3-10.7) after atrial procedures (p=0.003). Development of heart rate was significantly different (p=0.001), with higher rates in adolescents after an arterial switch. Twenty-four-hour recordings were abnormal in five of 72 patients following arterial correction, disclosing excessive ventricular extrasystoles in four (three monomorphic, one polymorphic) and a wandering pacemaker in one. After atrial procedures, 11 of 19 were abnormal (p<0.001), with sinus or atrial bradycardia in eight, atrial flutter in two, and monomorphic ventricular tachycardias in one. Abnormal findings on either 12-lead or 24-hour electrocardiograms were seen in 22% of patients following an arterial switch procedure and 83% of patients undergoing atrial redirection (p<0.001). Sinus rhythm, therefore, is preserved longer and arrhythmias are less frequent and less severe after the arterial switch operation than after the Mustard or Senning operations.
