AbstractPrematurity is a risk factor for adverse outcomes after arterial switch operation in newborns with d-TGA (d-TGA). In this study, we sought to investigate the impact of prematurity on postnatal and perioperative clinical management, morbidity, and mortality during hospitalization in neonates with simple and complex d-TGA who received arterial switch operation (ASO). Monocentric retrospective analysis of 100 newborns with d-TGA. Thirteen infants (13.0%) were born premature. Preterm infants required significantly more frequent mechanical ventilation in the delivery room (69.2% vs. 34.5%, p = 0.030) and during the preoperative course (76.9% vs. 37.9%, p = 0.014). Need for inotropic support (30.8% vs. 8.0%, p = 0.035) and red blood cell transfusions (46.2% vs. 10.3%, p = 0.004) was likewise increased. Preoperative mortality (23.1% vs 0.0%, p = 0.002) was significantly increased in preterm infants, with necrotizing enterocolitis as cause of death in two of three infants. In contrast, mortality during and after surgery did not differ significantly between the two groups. Cardiopulmonary bypass times were similar in both groups (median 275 vs. 263 min, p = 0.322). After ASO, arterial lactate (34.5 vs. 21.5 mg/dL, p = 0.007), duration of mechanical ventilation (median 175 vs. 106 h, p = 0.038), and venous thrombosis (40.0% vs. 4.7%, p = 0.004) were increased in preterm, as compared to term infants. Gestational age (adjusted unit odds ratio 0.383, 95% confidence interval 0.179–0.821, p = 0.014) was independently associated with mortality. Prematurity is associated with increased perioperative morbidity and increased preoperative mortality in d-TGA patients.

Objective: Neoaortic valve regurgitation which might be related to root dilatation is one of the major concerns following arterial switch operation (ASO) for transposition of the great arteries (TGA). This study investigated the effect of bicuspid neoaortic valve on neoaortic root morphology, function, and the long-term clinical outcomes after ASO for TGA using propensity score matching (PSM). Methods: From 1997 to 2018, 442 patients underwent ASO for TGA. Patients who underwent staged repair (n=15), were repaired at extremely old age (> 1 year, n=9), and died before discharge (n=46), and were lack of echocardiographic data at discharge (n=20) were excluded. Among a total of 352 eligible patients, 18 patients (5.1%) had a BPV. After PSM (1:4), 15 patients with BPV and 60 corresponding patients with tricuspid pulmonary valve were enrolled for analysis. Results: Baseline characteristics in both groups were similar. The median duration of follow-up was 9.9 years (4 months ~ 22.3 years). There was one late death. Freedom from reoperation at 10 years was 93.3 ± 6.4 % in bicuspid group and 88.7 ± 4.4 % in tricuspid group ( p =0.84). Reoperation for aortic valve or aortic root was rarely required during follow-up. Indexed dimension (z-score) of neoaortic annulus was not increased in both groups ( p =0.57) (Figure 1A), although there was a little increasing tendency in z-score of neoaortic sinus without intergroup difference ( p =0.69) (Figure 1B). Deterioration in neoaortic valve function was more prominent in bicuspid group (common odds ratio; 1.40 in bicuspid group [ p <0.01], and 1.12 in tricuspid group [ p =0.03], p =0.03) (Figure 1C). Conclusions: Arterial switch operation could be a safe option in selected patients with TGA associated with BPV without increasing the risk of reoperation. Deterioration of aortic valve function was more prominent in bicuspid group, which suggests that the neoaortic valve function would be deteriorated mainly by valve itself not root pathology.

Abstract OBJECTIVES Coronary complications are still the main reason for early mortality after an arterial switch operation. The high incidence of coronary anomalies in patients with transposition of the great arteries may increase the difficulty of coronary transfer, and among them, an intramural pattern was shown to be an independent risk factor of early mortality. However, recently published studies have reported that this rare coronary variant has no impact on the survival rate. The aim of this study was to assess the frequency of intramural coronary patterns in patients with transposition and the impact on overall mortality after an arterial switch operation. Additionally, we presented all coronary arrangements associated with intramural patterns in our cohort and the surgical techniques used to manage them successfully. METHODS All arterial switch operations were retrospectively reviewed. In each case, the surgical reports contained detailed graphical representations and coronary anatomy patterns. All operatively confirmed intramural patterns were included in the analysis. RESULTS Among 806 patients, 271 patients had coronary anomalies (33.62%), and 28 patients had an intramural pattern (3.47%), which was frequently associated with other complex coronary anomalies (P &lt; 0.001). Overall survival was significantly higher in patients with intramural coronary artery patterns than in those with other coronary variants (21.34% vs 8.74%, P = 0.024, log-rank test). CONCLUSIONS Intramural patterns associated with transposition remain a surgical challenge and increase overall mortality in our cohort. To reliably confirm or reject the significance of the observed impact of this rare coronary variant, a multicentre data analysis is required.

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.
