Abstract
Objectives This study was to assess the mid-term results of the one-and-a-half ventricular repair (hemi-Mustard and bidirectional Glenn procedures combined with the Rastelli procedure) and Fontan pathway for correcting congenitally corrected transposition of great artery (ccTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malposition. Methods In this retrospective study, 74 consecutive ccTGA with LVOTO and cardiac malposition underwent the one-and-a-half ventricular repair (group A; 33 cases) and Fontan operation (group B; 41 cases) between October 2011 and March 2018. The Median follow-up time was 49 (20–84) and 42 (7–85) months in groups A and B, respectively. To estimate excise tolerance the 6-min walk test (MWT) was performed. Results No in-hospital death. Compared with group A, group B have significantly less CPB, mechanical ventilation time, and intensive care unit stay, but prolonged pleural effusions developed more frequently in Group B. The survival probability was 90.2% (95% CI, 80.2–100%) and 97.2% (95% CI, 92–100%) at 7 years (p = 0.300) in group A and B. The probability of freedom from re-intervention were 80.6% (95% CI, 66.5–97.6%) and 97.2% (95% CI, 92–100%) at 7 years (p = 0.110). Longitudinal repeated measured echo data at every follow-up time shows that group A has more systemic ventricular EF% (p < 0.001) and less moderate systemic ventricular valve regurgitation (p < 0.001) compared with group B. Estimated by 6 MWT, group A has better outcomes for 6-min walk distance. Conclusions For correction of ccTGA with LVOTO and cardiac malposition, the one-and-a-half ventricular repair had superior midterm heart function and excise tolerance.

Abstract
BACKGROUND Optimal management for congenitally corrected transposition of the great arteries (ccTGA) is controversial. We applied different surgical strategies based on individual variations in our single-centered practice over 10 years, aming to describe the mid-term results. METHODS From January 2008 to June 2021, 90 patients with ccTGA were reviewed and grouped by three different surgical strategies: 41 cases with biventricular correction as biventricular group, 11 cases with 1.5 ventricular correction as 1.5 ventricular group, and 38 cases with Fontan palliation as univentricular group. The mean age at primary surgery was 41.4 ± 22.7 months. Patients were followed for mortality, complications, reoperation, cardiac function, and valve status. RESULTS The median follow-up period was 5.1 years (range, 1.5-12.5 years). The overall 10-year survival and freedom from reoperation rate was 86.7 and 82.4%, respectively. There were 3 early deaths and 3 mid-term deaths in the biventricular group, while 2 early deaths and 1 mid-term deaths were reported in the univentricular group. Although 1.5 ventricular group presented no death and the fewest complications, we still found similar mortality (p = 0.340) and morbidity (p = 0.670) among the three groups. The bypass time, aortic-clamp time, and ICU stay length were the longest in the biventricular group, followed by the 1.5 ventricular group (p < 0.001). However, in mid-term follow-up, biventricular and 1.5 ventricular groups both showed excellent cardiac function and obvious improvement of tricuspid regurgitation (p = 0.008 and p = 0.051, respectively). Fontan palliation provided acceptable mid-term outcomes as well, despite a lower ejection fraction. CONCLUSION Satisfactory mid-term outcomes could be achieved for highly selected ccTGA patients using the whole spectrum of surgical techniques. Moreover, 1.5 ventricular correction, as a new emerging technique in recent years, might hold great promise in future practice.

Abstract
Surgery for complex congenitally corrected transposed great arteries is one of the greatest challenges in cardiovascular surgery. We report our experience with bidirectional Glenn shunt placement as a palliative procedure for complex congenitally corrected transposition. We retrospectively identified 50 consecutive patients who had been diagnosed with congenitally corrected transposition accompanied by left ventricular outflow tract obstruction and ventricular septal defect and who had then undergone palliative bidirectional Glenn shunt placement at our institution from January 2005 through December 2014. Patients were divided into 3 groups according to subsequent surgeries: Fontan completion (total cavopulmonary connection, 13 patients) (group 1), anatomic repair (hemi-Mustard and Rastelli procedures without Glenn takedown, 11 patients) (group 2), and prolonged palliation (no further surgery, 26 patients) (group 3). After shunt placement, no patient died or had ventricular dysfunction. Overall, mean oxygen saturation increased significantly from 79.5% ± 13.5% preoperatively to 94.1% ± 7.3% (P <0.001). The median time from shunt placement to Fontan completion and anatomic repair, respectively, was 2.1 years (range, 1.6-5.2 yr) and 1.1 years (range, 0.6-2.4 yr). Only 2 late deaths occurred, both in group 1. In group 3, time from shunt placement to latest follow-up was 4.5 years (range, 2.3-8 yr). At latest follow-up, mean oxygen saturation was 91.6% ± 10.3%, and no patients had impaired ventricular function. Bidirectional Glenn shunt placement as an optional palliative procedure for complex congenitally corrected transposition has favorable outcomes. Later, patients can feasibly be treated by Fontan completion or anatomic repair. Use of a bidirectional Glenn shunt for open-ended palliation is also acceptable.

Abstract
OBJECTIVES The hemi-Mustard and bidirectional Glenn (BDG) procedures combined with the Rastelli procedure have been applied to selected cases of congenitally corrected transposition of the great arteries (ccTGA) for potential benefit over the classic atrial switch procedure. The aim of this study was to analyse our experience with the hemi-Mustard, BDG and Rastelli procedures as an anatomical correction for patients with ccTGA/left ventricular outflow tract obstruction (LVOTO) with positional heart anomalies. METHODS In this retrospective study, 31 consecutive patients with corrected transposition underwent the hemi-Mustard/BDG procedures with the Rastelli operation between 2011 and 2015. The median age was 5.4 (range: 0.75-12) years. Positional anomalies were present in all patients. Eleven patients underwent BDG initially; they then had the second-stage hemi-Mustard and Rastelli procedures; 'one-stage repair' (hemi-Mustard/BDG and the Rastelli procedures) was performed in 20 cases. RESULTS There were no in-hospital deaths, and 3 patients received a pacemaker. One patient had an atrial baffle obstruction that was observed in the early postoperative period; 7 patients had prolonged pleural effusions that developed more frequently in the one-stage repair group (7/20 vs 0/11, P = 0.033). During the mean follow-up of 3.3 years, 1 late death was noted, and no conduit replacements were required. Twenty-five (83.3%) patients are in New York Heart Association classes I and II at the latest follow-up. CONCLUSIONS Hemi-Mustard, BDG and the Rastelli procedures are technically feasible for correction of ccTGA/left ventricular outflow tract obstruction (LVOTO) and cardiac malposition. Nevertheless, postoperative pleural effusion is the most prevalent complication in the one-stage repair. Two-stage repair may reduce the risk of pleural effusion-related complications.

Abstract
Background and Objectives The aims of this study were to determine the early and late outcomes of anatomic repair of congenitally corrected transposition of the great arteries (ccTGA) and to evaluate effectiveness of the hemi-Mustard procedure. Subjects and Methods We conducted a retrospective, single-center study of patients who underwent anatomic repair for ccTGA between July 1996 and December 2013. Sixteen patients were included in the study. The median age at the time of the operation was 3.5 years (range: 0.5-29.7), and the median body weight was 13.3 kg (range: 5.8-54). The median follow-up duration was 7.7 years (range: 0.2-17.4). Results Atrial switch was achieved using the Mustard procedure in 12 patients (hemi-Mustard procedure in 11) or the Senning procedure in four patients. The ventriculoarterial procedure was performed using the Rastelli procedure in 11 patients and arterial switch in five patients. Six patients underwent tricuspid valvuloplasty. The survival rate was 93.8±6.1%. The rate of freedom from reoperation at 5 years was 92.3±7.4% in the Rastelli group. All patients except one were New York Heart Association class I. All patients except one had mild tricuspid regurgitation. Conclusion Anatomic repair can be performed with a low risk of in-hospital mortality. The hemi-Mustard strategy for selected patients is one solution for reducing early mortality and morbidity, and long-term complications such as venous pathway stenosis or sinus node dysfunction.

Abstract
OBJECTIVES We report our surgical experience in congenitally corrected transposition of great arteries (CCTGAs) and the long-term follow-up result. METHODS From January 1995 to February 2012, 56 patients with CCTGA received definite surgical repair; 15 patients received conventional repair (Group I), 18 patients received anatomical repair (Group II) and 23 patients received single ventricular palliation (Group III). They were followed for early and late mortality, long-term survival, postoperative morbidity and reintervention or reoperation. RESULTS The overall survival rate was 80% at 16 years in Group I, 53% at 13 years in Group II and 100% at 13 years in Group III. After excluding the early surgical mortality, the long-term survival rate was 92% at 16 years in Group I, 64% at 13 years in Group II and 100% at 13 years in Group III. Patients with significant tricuspid valve regurgitation showed the worst outcome after surgery. CONCLUSIONS Our series showed good results with single ventricular palliation (SVP) in CCTGA with complex anatomy, but the long-term result should be followed. Anatomical repair is the choice of operation only for those with favourable anatomy. The more complicated intracardiac repair may result in late left ventricular outflow tract obstruction, various degrees of atrioventricular block, systemic or pulmonary venous return obstruction and the lack of an ideal conduit (e.g. homograft) for Rastelli reconstruction. Therefore, we preferred SVP in patients with complex and unfavourable anatomy.

Abstract
OBJECTIVES The Senning or Mustard procedure combined with the arterial switch operation (ASO) (± VSD and no left ventricular (LV) outflow tract obstruction) or the Rastelli operation (VSD and LV outflow tract obstruction) has become the preferred strategy over conventional repair as it is thought to prevent long-term dysfunction of the right ventricle (RV). More recently, hemi-Mustard rerouting of blood from the inferior vena cava to the RV in combination with bidirectional cavopulmonary anastomosis (BCPA) has been adopted by some centres for potential benefits over the classic atrial switch procedure. The aim of this study was to analyse our experience with hemi-Mustard and BCPA as part of an anatomical repair of congenitally corrected transposition of the great arteries (CCTGA) in selected patients. METHODS Between 2004 and 2011, eight patients underwent hemi-Mustard/BCPA with the Rastelli operation (n = 6) or ASO (n = 2). The median age was 2.9 (range: 1.2-9.1) years. Positional anomalies were present in 75% of the patients. Both patients with ASO had dysplastic and insufficient tricuspid valves. In the Rastelli group, four patients had previously received shunts followed by BCPA in one patient. In the ASO group, both patients underwent pulmonary artery banding initially. RESULTS There was one in-hospital death and no late mortality. Two patients received a pacemaker. One patient from the Rastelli group required conduit change 6 years later. At the mean follow-up of 4.5 years, six and one patients are in NYHA classes I and II, respectively; six patients showed good biventricular function, while one had LV dysfunction. Systemic venous obstruction and sinus node dysfunction were not observed, and BCPA was functioning well in all patients. CONCLUSIONS Hemi-Mustard/BCPA is useful in anatomical repair of CCTGA in selected patients. When compared with the classic atrial switch operation, it is technically easier which makes it especially helpful in atrio-apical discordance; it unloads an RV with limited size or function, and avoids complications related to the upper limb of the classic atrial switch procedure. Mid-term results of this approach are favourable. Further follow-up is needed to prove long-term benefits.

Abstract
Congenitally corrected transposition of the great arteries (ccTGA) is a complex cardiac anomaly with an unfavorable natural history. Surgical treatment has been available for over 50 years. Initial procedures used for ccTGA did not correct atrio-ventricular discordance, leaving the right ventricle in systemic position. In the past two decades anatomic repair has been considered to be a better option. Many cases subjected to anatomic repairs would also be suitable for the Fontan strategy, which probably has a lower initial risk. The rationale for use of the Fontan operation in management of congenitally corrected transposition is discussed in this review, with comparisons to other strategies.

Abstract
Anatomic correction of congenitally corrected transposition of the great arteries (ccTGA) has brought about the renaissance of the atrial switch. The Senning procedure has become the most widely used variant because of the lower incidence of pathway obstruction, baffle leak, and significant late arrhythmias. It is for this reason the Senning is discussed in detail here. The technical steps of the Senning are both ingenious and unique amongst cardiac surgical procedures. They must be made as safe and reproducible as possible because the procedure is no longer commonly performed and trainee surgeons may have only very limited exposure to these types of operation. In addition to its infrequency, there are additional technical issues regarding the atrial switch in the setting of ccTGA, particularly in relation to associated malposition of the heart and the conduction system. Outcomes for the Senning procedure in ccTGA have been very good, with early complications being extremely rare. Obstruction to the superior vena cava pathway has been recorded in less than 3% of cases and can usually be managed by interventional catheterization. Late problems with atrial arrhythmias have not been widely reported, but this may reflect the relatively short follow-up for these patient cohorts compared with older series in d-TGA.
