World J Cardiol 2023; 15:542-552. [PMID: 37900900 PMCID: PMC10600789 DOI: 10.4330/wjc.v15.i10.542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 08/23/2023] [Accepted: 09/27/2023] [Indexed: 10/24/2023] Open
Abstract
BACKGROUND Congenitally corrected levo-transposition of the great arteries (L-TGA) is a congenital heart disease in which the ventricles and great arteries are transposed from their typical anatomy. In L-TGA, the double discordance, atrioventricular and ventriculoarterial, create an acyanotic milieu which allows patients to survive their early decades, however, progressive systemic right ventricle (sRV) dysfunction creates complications later in life. sRV dysfunction and remodeling predisposes patients to intracardiac thrombus (ICT) formation. CASE SUMMARY A 40-year-old male with L-TGA presented with symptoms of acute decompensated heart failure. In childhood, he had surgical repair of a ventricular septal defect. In adulthood, he developed sRV dysfunction, systemic tricuspid valve (sTV) regurgitation, and left-bundle branch block for which he underwent cardiac resynchronization therapy. Transthoracic echocardiogram showed a sRV ejection fraction of 40%, severe sTV regurgitation, and a newly identified sRV ICT. ICT was confirmed by ultrasound-enhancing agents and transesophageal echocardiography. Our patient was optimized with guideline-directed medical therapy and diuresis. Anticoagulation was achieved with a vitamin K antagonist (VKA) and he was later referred for evaluation by advanced heart failure and heart transplant services. CONCLUSION Anticoagulation with VKA is the mainstay of treatment in the absence of conclusive data supporting direct oral anticoagulant use in ICT in patients with congenital heart disease. This case illustrates the natural history of L-TGA and highlights the importance of surveillance and monitoring with dedicated cardiac imaging to identify complications.

Miller JR, Sebastian V, Eghtesady P. Management Options for Congenitally Corrected Transposition: Which, When, and for Whom? Semin Thorac Cardiovasc Surg Pediatr Card Surg Annu 2022; 25:38-47.

Abstract
Management strategies for congenitally corrected transposition of the great arteries (ccTGA) historically consisted of a physiologic repair, resulting in the morphologic right ventricle (mRV) supporting systemic circulation. This strategy persisted despite the development of heart failure by middle age because of the reasonable short-term outcomes, and the natural history of some patients with favorable anatomy (felt to demonstrate the mRV's ability to function in the long-term), and due to the less-than-optimal outcomes associated with anatomical repair. As outcomes with anatomical repair improved, and the long-term risk of systemic mRV dysfunction became apparent, more have begun to realize its advantages. In addition to the decision on whether or not to pursue anatomical repair, and the optimal timing, studies demonstrating the nuance to morphologic left ventricle retraining have demonstrated its feasibility. Further considerations in ccTGA have begun to be better understood, including: the management of a poorly functioning mRV, systemic tricuspid valve regurgitation, the utility of morphologic left ventricle outflow tract obstruction (native or surgically created) and pacing strategies. While some considerations are apparent: biventricular pacing is superior to univentricular, tricuspid regurgitation must be managed early with either progression towards anatomical repair (pulmonary artery banding if needed for retraining) or tricuspid replacement (not repair) based on the patient's age; others remain to be completely elucidated. Overall, the heterogeneity of ccTGA, as well as the unique presentation with each patient regarding ventricular and valvular function and center-to-center variability in management strategies has made the interpretation of published data difficult. That said, more recent long-term outcomes favor anatomical repair in most situations.

Abstract
OBJECTIVE To determine the contemporary outcomes of the double switch operation (DSO) (ie, Mustard or Senning + arterial switch). METHODS A single-institution, retrospective review of all patients with congenitally corrected transposition of the great arteries undergoing a DSO. RESULTS Between 1999 and 2019, 103 patients underwent DSO with a Mustard (n = 93) or Senning (n = 10) procedure. Segmental anatomy was (S, L, L) in 93 patients and (I, D, D) in 6 patients. Eight patients had heterotaxy and 71 patients had a ventricular septal defect. Median age was 2.1 years (range, 1.8 months-40 years), including 34 patients younger than age 1 year (33%). Median weight was 10.9 kg (range, 3.4-64 kg). Sixty-one patients had prior pulmonary artery bands for a median of 1.1 years (range, 14 days-12.9 years; interquartile range, 0.7-3.1 years). Median intensive care unit and hospital lengths of stay were 5 and 10 days, respectively. Median follow-up was 3.4 years (interquartile range, 1-9.8 years) and 5.2 years (interquartile range, 2.3-10.7 years) in 79 patients with >1 year follow-up. At latest follow-up, aortic, mitral, tricuspid valve regurgitation, and left ventricle dysfunction was less than moderate in 96%, 98%, 96%, and 93%, respectively. Seventeen patients underwent reoperation: neoaortic valve intervention (n = 10), baffle revision (n = 5), and ventricular septal defect closure (n = 4). At latest follow-up, 17 patients (17%) had a pacemaker and 27 (26%) had cardiac resynchronization therapy devices. There were 2 deaths and 2 transplants. Transplant-free survival was 94.6% at 5 years. Risk factors for death or transplant included longer cardiopulmonary bypass time and older age at DSO. CONCLUSIONS The outcomes of the DSO are promising. Earlier age at operation might favor better outcomes. Progressive neoaortic regurgitation and reinterventions on the neo-aortic valve are anticipated problems.

Abstract
Background Ventricle retraining has been extensively studied by our laboratory. Previous studies have demonstrated that intermittent overload causes a more efficient ventricular hypertrophy. The adaptive mechanisms involved in the ventricle retraining are not completely established. This study assessed vascular endothelial growth factor (VEGF) expression in the ventricles of goats submitted to systolic overload. Methods Twenty-one young goats were divided into 3 groups (7 animals each): control, 96-hour continuous systolic overload, and intermittent systolic overload (four 12-hour periods of systolic overload paired with 12-hour resting period). During the 96-hour protocol, systolic overload was adjusted to achieve a right ventricular (RV) / aortic pressure ratio of 0.7. Hemodynamic evaluations were performed daily before and after systolic overload. Echocardiograms were obtained preoperatively and at protocol end to measure cardiac masses thickness. At study end, the animals were killed for morphologic evaluation and immunohistochemical assessment of VEGF expression. Results RV-trained groups developed hypertrophy of RV and septal masses, confirmed by increased weight and thickness, as expected. In the study groups, there was a small but significantly increased water content of the RV and septum compared with those in the control group (p<0.002). VEGF expression in the RV myocardium was greater in the intermittent group (2.89% ± 0.41%) than in the continuous (1.80% ± 0.19%) and control (1.43% ± 0.18%) groups (p<0.023). Conclusions Intermittent systolic overload promotes greater upregulation of VEGF expression in the subpulmonary ventricle, an adaptation that provides a mechanism for increased myocardial perfusion during the rapid myocardial hypertrophy of young goats.

Abstract
The long-term outcome of patients with corrected transposition of the great arteries and associated lesions after physiologic repair is uncertain. Anatomic correction, utilizing the morphologic left ventricle as a systemic pumping chamber and the mitral valve as the systemic atrioventricular valve, is considered the preferred method, especially for patients with either tricuspid valve regurgitation, with Ebstein's malformation of the tricuspid valve, or with right ventricular dysfunction. The double switch employs both an atrial switch and arterial switch to "correct" the atrioventricular and ventriculoarterial discordance. Associated lesions are also repaired. The best outcomes with double switch are achieved with patients in the first few years of life even if reconditioning of morphologic left ventricle is required. However, the long-term function of the conduction system, the aortic valve, and the ventricles is variable and requires close surveillance.

Abstract
BACKGROUND The outcomes of anatomical repair for patients with congenitally corrected transposed great arteries remain unclear and the indications for different procedures are poorly understood. METHODS From January 2005 to February 2016, consecutive corrected transposition patients who underwent anatomical repair at the current institution were enrolled in this retrospective study. Varied types of anatomical repair were individually customised. RESULTS A total of 85 patients were included. Fifty-one (51) and 35 patients presented with left ventricular outflow tract obstruction and cardiac malposition, respectively. Thirty-nine (39) patients presented with moderate-to-severe tricuspid regurgitation. Thirty-four (34), 19, and 32 patients underwent Senning arterial switch operations, Senning-Rastelli, and hemi-Mustard-Rastelli-bidirectional Glenn, respectively. Early after repair, there were five in-hospital deaths and nine re-operations. During 4.6 years (range, 0.5-10.3) of follow-up, seven late deaths were documented. Estimated overall survival rate after anatomical repair was 89.3%, 85.0%, and 85.0% at 1 year, 3 years, and 5 years, respectively. Instead of Senning-Rastelli, most (75.0%) early left ventricular dysfunctions were noted in patients who underwent Senning arterial switch procedures. However, all the late left ventricular dysfunctions were found in patients who underwent previous left ventricular retraining. In patients with left ventricular outflow tract obstruction, the hemi-Mustard-Rastelli-bidirectional Glenn shunt provided a lower early mortality (0% vs 15.8%, p = 0.047). CONCLUSIONS Favourable outcomes can be achieved for anatomical repair of corrected transposition. Left ventricular dysfunction was a significant postoperative issue. Hemi-Mustard-bidirectional Glenn-Rastelli procedure may provide benefits for patients with associated left ventricular outflow tract obstruction and cardiac malposition. Each procedure has its own advantages in varied anatomy.

Abstract
Introduction: Knowledge gaps exist in the life expectancy and functional outcome of patients with congenitally corrected transposition (ccTGA) presenting early in life, which is relevant in the evaluation of early anatomic repair. Methods: In a single-center analysis, 91 patients with ccTGA were identified over 25 years, of which 31 presented with biventricular anatomy in the first year of life and formed the study cohort. End points for analysis included survival, moderate or worse tricuspid valve regurgitation, and systemic right ventricle (RV) dysfunction. Median follow-up was 4.9 years (range: 7 days to 20 years). Results: Among 31 patients presenting in the first year of life, 9 (29%) never received cardiac surgery, while 22 (71%) underwent 36 cardiac operations. Overall freedom from moderate or severe systemic RV dysfunction was 75% at 10 years. Overall survival was 82% at 10 years. Surgical mortality was 5.6% (2/36). Among survivors with a systemic RV, 23 (100%) of 23 were Ross or NYHA class I or II at last follow-up. Conclusions: Congenitally corrected transposition presenting in the first year of life and maintaining a systemic RV can expect (1) long-term survival of more than 80% at 10 years, (2) low expected surgical mortality (overall 6%), and (3) 75% late freedom from major RV dysfunction at 10 years. Pending multi-institutional analyses, this experience with a systemic RV in ccTGA provides an initial benchmark for comparison when considering early elective anatomic correction.

Abstract
BACKGROUND Anatomic correction of corrected transposition of the great arteries with associated lesions, utilizing the morphologic left ventricle as a systemic pumping chamber, is the preferred method in many centers. The purpose of this study was to analyze functional outcome after anatomic correction. METHODS Between Jan 1997 and May 2016, 63 patients with corrected transposition of the great arteries and associated lesions underwent anatomic correction. Forty-two patients (67%) underwent palliation before correction, including 14 patients (22%) who required training of systemic ventricle. The double switch procedure was performed in 37 patients; 25 patients underwent the Senning-Rastelli operation, and 1 patient underwent the Senning-Nikaidoh procedure. The median age at correction was 1.6 ± 3.7(SD) years (range, 0.2 to 17.8 years). RESULTS The survival and freedom from any event was 95% and 71%, respectively, at 15-year follow-up. The combined freedom from death, failure of systemic ventricle, or heart transplant was 93% at 15-year follow-up regardless of procedure type. Sinus rhythm was present in 49 patients, with 14 patients requiring pacemaker (22%)-8 preoperatively, 4 early postoperatively, and 2 late postoperatively. Neurological development is normal in all patients. Fifty-four percent of the patients are not on medication. CONCLUSIONS Anatomic correction of corrected transposition of the great arteries is a safe procedure that provides encouraging survival and functional benefits. Ninety-three percent preservation of morphological left ventricle function in 15 years of follow-up supports the concept of anatomic correction. Longer follow-up is needed to confirm superiority of this approach over other management strategies.

Abstract
In recent decades, significant progress has been made in the diagnosis and management of congenitally corrected transposition of the great arteries (ccTGA). Nevertheless, gradual dysfunction and failure of the right ventricle (RV) in the systemic circulation remain the main contributors to mortality and disability for patients with ccTGA, especially after adolescence. Anatomic repair of ccTGA effectively resolves the problem of failure of the systemic RV and has good early and midterm results. However, this strategy is applicable primarily in infants and children up to their teens and has associated risks and limitations, and new challenges can arise in the late postoperative period. Patients with ccTGA manifesting progressive systemic RV dysfunction beyond adolescence represent the major challenge. Several palliative options such as cardiac resynchronization therapy, tricuspid valve repair or replacement, pulmonary artery banding, and implantation of an assist device into the systemic RV can be used to improve functional status and to delay the progression of ventricular dysfunction in patients who are not suitable for anatomic correction of ccTGA. For adult patients with severe systemic RV failure, heart transplantation currently remains the only long-term lifesaving procedure, although donor organ availability remains one of the most limiting factors in this type of therapy. This review focuses on current surgical and medical strategies and interventional options for the prevention and management of systemic RV failure in adults and children with ccTGA.

Impact of pacing on systemic ventricular function in L-transposition of the great arteries. J Thorac Cardiovasc Surg 2015; 151:131-8. [PMID: 26410005 DOI: 10.1016/j.jtcvs.2015.08.064] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2015] [Revised: 07/22/2015] [Accepted: 08/11/2015] [Indexed: 11/21/2022]
Abstract
OBJECTIVE(S) To assess the impact of univentricular versus biventricular pacing (BiVP) on systemic ventricular function in patients with congenitally corrected transposition of the great arteries (ccTGA). METHODS We performed a retrospective review of all patients with a diagnosis of ccTGA who underwent pacemaker insertion. From 1993 to 2014, 53 patients were identified from the cardiology database and surgical records. RESULTS Overall mortality was 7.5% (n = 4). One patient required transplantation and 3 late deaths occurred secondary to end-stage heart failure. Median follow-up was 3.7 years (range, 4 days to 22.5 years). Twenty-five (47%) underwent univentricular pacing only, of these, 8 (32%) developed significant systemic ventricular dysfunction. Twenty-eight (53%) received BiVP, 17 (26%) were upgraded from a dual-chamber system, 11 (21%) received primary BiVP. Fourteen (82%) of the 17 undergoing secondary BiVP demonstrated systemic ventricular dysfunction at the time of pacer upgrade, with 7 (50%) demonstrating improved systemic ventricular function after pacemaker upgrade. Overall, 42 (79%) patients underwent univentricular pacing, with 22 (52%) developing significant systemic ventricular dysfunction. In contrast, the 11 (21%) who received primary BiVP had preserved systemic ventricular function at latest follow-up. CONCLUSIONS Late-onset systemic ventricular dysfunction is a major complication associated with the use of univentricular pacing in patients with ccTGA. All patients with ccTGA who develop heart block should undergo primary biventricular pacing, as this prevents late systemic ventricular dysfunction. Preemptive placement of BiVP leads at the time of anatomical repair or other permanent palliative procedure will facilitate subsequent BiVP should heart block develop.

Abstract
The traditional surgical approach (physiologic repair) of congenitally corrected transposition of the great arteries (ccTGA) attempts at restoring normal physiology by repairing the associated lesions. It fails to address the most serious anatomic abnormality, mainly ventriculoarterial discordance, and results in less than optimal long-term outcomes. Anatomic repair was introduced to incorporate the left ventricle into the systemic circulation. The excellent short-term and intermediate results of the double switch operation and its modifications make it the procedure of choice for the treatment of ccTGA.

Abstract
OBJECTIVE Early results for anatomic repair of congenitally corrected transposition of the great arteries (ccTGA) are excellent. However, the development of left ventricular dysfunction late after repair remains a concern. In this study we sought to determine factors leading to late left ventricular dysfunction and the impact of cardiac resynchronization as a primary and secondary (upgrade) mode of pacing. METHODS From 1992 to 2012, 106 patients (median age at surgery, 1.2 years; range, 2 months to 43 years) with ccTGA had anatomic repair. A retrospective review of preoperative variables, surgical procedures, and postoperative outcomes was performed. RESULTS In-hospital deaths occurred in 5.7% (n = 6), and there were 3 postdischarge deaths during a mean follow-up period of 5.2 years (range, 7 days to 18.2 years). Twelve patients (12%) developed moderate or severe left ventricular dysfunction. Thirty-eight patients (38%) were being paced at latest follow-up evaluation. Seventeen patients had resynchronization therapy, 9 as an upgrade from a prior dual-chamber system (8.5%) and 8 as a primary pacemaker (7.5%). Factors associated with left ventricular dysfunction were age at repair older than 10 years, weight greater than 20 kg, pacemaker implantation, and severe neo-aortic regurgitation. Eight of 9 patients undergoing secondary cardiac resynchronization therapy (upgrade) improved left ventricular function. None of the 8 patients undergoing primary resynchronization developed left ventricular dysfunction. CONCLUSIONS Late left ventricular dysfunction after anatomic repair of ccTGA is not uncommon, occurring most often in older patients and in those requiring pacing. Early anatomic repair and cardiac resynchronization therapy in patients requiring a pacemaker could preclude the development of left ventricular dysfunction.

Impact of age and duration of banding on left ventricular preparation before anatomic repair for congenitally corrected transposition of the great arteries. Ann Thorac Surg 2013; 96:603-10.

Abstract
BACKGROUND The optimal age and duration of left ventricular (LV) training in congenitally corrected transposition (ccTGA) with an unprepared LV is unknown. The objective of this study was to review the effect of age at pulmonary artery banding (PAB) and duration of ventricular training on LV function and aortic regurgitation (AR) after anatomic repair. METHODS The medical records of all patients who underwent PA banding for LV training between 1998 and 2011 were retrospectively reviewed. The primary end points were moderate or more LV dysfunction and moderate or more AR after anatomic repair. RESULTS During the study period, 25 patients with ccTGA underwent PAB for LV preparation. There was 1 early death. Eighteen patients underwent anatomic repair at a median of 10 months (range, 2 weeks to 11 years) from PAB. At the most recent follow-up after anatomic repair, moderate AR developed in 1 patient, and moderate or more LV dysfunction developed in 4. LV dysfunction developed in 4 of 6 patients banded after 2 years of age, compared with 0 of 12 patients banded before 2 years (p = 0.005). After anatomic repair, LV dysfunction developed in 4 of 7 patients repaired after age 3 years compared with 0 of 11 repaired before 3 years (p = 0.01). CONCLUSIONS Early PAB strategy is associated with favorable LV and neoaortic valve function after anatomic repair for ccTGA with an unprepared LV. Candidates for anatomic repair who require LV training should be referred early in infancy for consideration of appropriate timing of PAB.

Abstract
The evolution of surgical techniques for transposition of the great arteries (TGA) provides a moving target for the assessment of late arrhythmias. Imposed on varying anatomical substrates are progressive surgical interventions, each with its own set of sequelae. Analysis of the risk of arrhythmia development requires division into which arrhythmia is present, for which form of transposition, undergoing what type of surgery, and in which surgical era. For purposes of this review, available data on d-TGA undergoing Senning repairs, Mustard repairs, and arterial switch repairs and congenitally corrected TGA undergoing double switch repairs are reviewed.

Abstract
Survival of patients with congenital heart defects has improved dramatically. Many will undergo interventional catheter or surgical procedures later in life. Others will develop atherosclerotic or post-surgical coronary heart disease. The coronary artery anatomy in patients with congenital heart disease differs substantially from that seen in the structurally normal heart. This has implications for diagnostic procedures as well as interventions. The unique epicardial course seen in some defects could impair interpretation of coronary angiograms. Interventional procedures, especially at the base of the heart, risk injuring unusually placed coronary arteries so that coronary artery anatomy must be delineated thoroughly prior to the procedure. In this review, we will describe the variants of coronary artery anatomy and their implications for interventional and surgical treatment and for sudden death during late follow-up in several types of congenital heart defects including: tetralogy of Fallot, truncus arteriosus, transposition of the great arteries, double outlet right ventricle, congenitally corrected transposition of the great arteries and defects with functionally one ventricle. We will also discuss the coronary abnormalities seen in Kawasaki disease.

Abstract
OBJECTIVE(S) Anatomic repair for congenitally corrected transposition of the great arteries (ccTGA) has been shown to improve patient survival. We sought to examine long-term outcomes in patients after anatomic repair with focus on results in high-risk patients, the fate of the neo-aortic valve, and occurrence of morphologically left ventricular dysfunction. METHODS We conducted a retrospective, single-institution study of patients undergoing anatomic repair for ccTGA. A total of 113 patients from 1991 to March 2011 were included. Double-switch (DS) repair was performed in 68 patients, with Rastelli-Senning (RS)-type repair in 45. Pulmonary artery banding for retraining was performed in 23 cases. Patients were followed up for survival status, morbidity, and reinterventions. A subgroup of 17 high-risk patients in severe heart failure, ventilated, and on inotropes before repair, were included. RESULTS Median age at repair was 3.2 years (range, 25 days to 40 years) and weight was 14.3 kg (3.2-61.4). There were 5 (of 68; 7.4%) early deaths in the DS group and 0 (of 45) in the RS group. Actuarial survivals in the DS group were 87.6%, 83.9%, 83.9% at 1, 5, and 10 years versus 91.6%, 91.6%, 77.3% in the RS group (log-rank: P = .98). Freedom from death, transplantation, or heart failure was significantly better in the RS group at 10 years (P = .03). There was no difference in reintervention at 10 years (DS, 50.3%; RS, 49.1%; P = .44). In the DS group, the Lecompte maneuver was associated with late reinterventions on the pulmonary arteries. Overall survival in the high-risk group was 70.6%. During follow-up, 14.2% patients had poor function of the morphologically left ventricle, all in the DS group, but this was not related to preoperative status or previous banding. The majority of patients after DS had mild aortic incompetence, which appeared well tolerated. Annuloplasty of the aortic root at time of DS reduced the risk of late aortic valve replacement. CONCLUSIONS There is significant morbidity after anatomic repair of ccTGA, which is higher in the DS than the RS group. Nevertheless, the majority of patients are free of heart failure at 10 years, including high-risk patients in severe heart failure before repair. Aortic annuloplasty may reduce risk of late aortic insufficiency.

Abstract
In the current era of anatomical correction of complete transposition of the great arteries, the Senning operation is reserved only for the atrial switch part of anatomical corrections of congenitally corrected transposition of the great arteries. These rare operations are performed in only a few centers all over the world; the majority of practicing cardiac surgeons therefore have limited experience with the Senning operation. The proposed modified Senning procedure might simplify the original concept. Once the technical aspect of the procedure is accomplished, the risk of systemic and pulmonary baffle obstructions is minimal, even in situs solitus with dextrocardia or situs inversus with levocardia. Furthermore, this technique has the potential to provide adequate capacity of the pulmonary venous atrium, to preserve optimal geometry of the mitral valve, to minimize damage of sinus node and to make the coronary sinus accessible for electrophysiological studies or intervention by keeping the coronary sinus in the systemic venous baffle. The modified technique is simple, highly reproducible and applicable, regardless of the situs and position of the apex of the heart.

Abstract
BACKGROUND This study was undertaken to evaluate long-term results of biventricular repairs for congenitally corrected transposition of the great arteries, and to analyze the risk factors that affect mortality and morbidity. METHODS Between 1983 and 2009, 167 patients with congenitally corrected transposition of the great arteries underwent biventricular repairs. The physiologic repairs were performed in 123 patients, and anatomic repairs in 44. Average follow-up was 9.3 +/- 6.6 years. RESULTS Kaplan-Meier estimated survival was 83.3% +/- 0.5% at 25 years in biventricular repair. In anatomic repair, left ventricular training and right ventricular dysfunction had negative impact on survival, but bidirectional cavopulmonary shunt had positive impact on survival. The reoperation-free ratio was 10.1% +/- 7.8% at 22 years after physiologic repair, and 46.2% +/- 12.4% at 15 years after anatomic repair (p = 0.885). Freedom from any arrhythmia was 49.6% +/- 7.5% at 22 years after physiologic repair, and 60.8% +/- 14.8% at 18 years after anatomic repair (p = 0.458). Freedom from systemic atrioventricular valve and ventricular dysfunction as well as tricuspid valve and right ventricular dysfunction was significantly higher in anatomic repair than in physiologic repair. CONCLUSIONS Long-term results of biventricular repair were satisfactory. Patients presenting with right ventricular dysfunction or need for left ventricular training represent a high-risk group of anatomic repair for which selection criteria are particularly important. Late functional outcomes of anatomic repair were excellent compared with physiologic repair. Anatomic repair is the procedure of choice for those patients if both ventricles are adequate or if surgical technique is modified with the help of additional a bidirectional cavopulmonary shunt.

Abstract
BACKGROUND Anatomic repair of congenitally corrected transposition of the great arteries has become a useful surgical strategy with potential advantages over conventional surgical repair. We describe early and intermediate outcomes after anatomic repair and analyze potential risk factors influencing these outcomes. METHODS A retrospective review was performed on all patients undergoing anatomic repair between January 1993 and January 2009. The primary outcome was in-hospital mortality. Variables potentially associated with outcome were identified a priori. Bivariate analyses were performed to determine the association between these variables and all outcome measures. RESULTS In 65 patients who underwent anatomic repair, 35 had Senning/arterial switch and 30 had Senning/Rastelli. Early and intermediate survival rates for Senning/arterial switch operations were 94% and 91%, respectively. Repairs were successful in patients with tricuspid regurgitation, left ventricular outflow obstruction, and left ventricular dysfunction. Predictors of outcome were not identified in this subset. Early and intermediate survival rates for Senning/Rastelli operations were 77% and 60%, respectively. Longer aortic cross-clamp (p = 0.03) and cardiopulmonary bypass times (p = 0.01) were associated with mortality. Ventricular septal defect enlargement was associated with surgical heart block (p < 0.01). Age, prior procedures, atrial-apical discordance, and tricuspid regurgitation were not associated with outcome. CONCLUSIONS Senning/arterial switch operations can be performed with excellent intermediate-term outcomes in patients with lesions previously thought to confer higher risk. Candidates for Senning/Rastelli procedures may be at increased risk for postoperative morbidity and mortality. More data are necessary to determine factors influencing outcome after anatomic repair.

Abstract
Congenitally corrected transposition of the great arteries (CCTGA) in the absence of major cardiac anomalies is thought to have a good outcome, although this has not been well documented. The objective of the present study was to compare the characteristics and outcomes of patients with a prenatal diagnosis of CCTGA to the characteristics and outcomes of those diagnosed postnatally. The optimal outcome was defined as intervention-free survival. All patients with CCTGA diagnosed prenatally and postnatally from 1999 to 2006 at 2 tertiary care institutions were reviewed. Patients with a single ventricle, heterotaxy, or valvar atresia were excluded. The differences between groups were assessed using the t test and chi-square test. A total of 54 patients (16 prenatal with 14 live born and 39 postnatal) were included. The patients diagnosed prenatally were diagnosed at a median gestational age of 20 weeks (range 16 to 37). Two deaths in each group were due to heart failure. The intervention-free survival rate for the prenatal and postnatal groups at 1, 6, and 36 months was 79%, 45%, and 30% and 85%, 61%, and 23%, respectively (p = NS). Of 37 patients, 14 (38%) underwent an arterial switch plus atrial baffling so that the morphologic left ventricle supported the systemic circulation, and 6 (16%) underwent repair of associated lesions so the morphologic right ventricle supported the systemic circulation; 4 (11%) of the 37 patients had pacemaker only. Prenatal patients with >1 fetal echocardiogram (12 of 14) did not have progression before birth. In conclusion, CCTGA has a >70% risk of intervention in the first 3 years after birth. The outlook is guarded and has an important effect on prenatal counseling.

OBJECTIVE Anatomic repair is being actively evaluated as the preferred option for congenitally corrected transposition of the great arteries. We present our 13-year experience with this approach. METHODS Between May 1994 and September 2007, 68 patients with congenitally corrected transposition of the great arteries underwent anatomic repair. Thirty-one patients (group 1, mean age of 94.8 +/- 42.3 months) underwent a combined Rastelli and atrial switch operation. Thirty-seven patients (group 2, mean age of 36.1 +/- 46.9 months) underwent an arterial switch operation and atrial rerouting. Eight patients in group 2 had an intact ventricular septum. RESULTS Group 1 had 5 early deaths (17%) but no late deaths. Three patients underwent conduit revision at a mean follow-up of 62 months. Group 2 had 5 early deaths (13.5%). There were 4 late reoperations (2 pulmonary baffle revisions, 1 mitral valve replacement, and 1 permanent pacemaker implantation) and 4 late deaths (1 secondary to progressive left ventricular dysfunction, 2 secondary to uncontrolled atrial tachyarrhythmia, and 1 secondary to pulmonary hypertension and right ventricular failure). In group 2, 4 patients have a left ventricular ejection fraction less than 40%, 5 patients have moderate aortic incompetence, 5 patients have symptomatic tricuspid incompetence, 1 patient has tricuspid stenosis, 1 patient has superior cava obstruction, and 3 patients are receiving antiarrhythmic therapy. CONCLUSION The occurrence of left ventricular dysfunction indicate that anatomic repair in the arterial switch group is still fraught with imperfections. The Rastelli group required conduit revisions but has otherwise performed well.

Abstract
The classical option for surgical repair in patients with congenitally corrected transposition takes advantage of the physiologic correction provided by nature. At the end of the surgical procedures, however, the morphologically right ventricle remains as the systemic ventricle. Surgical intervention is essentially the correction of associated lesions, including closure of ventricular septal defects, pulmonary valvotomy, placement of a conduit from the morphologically left ventricle to the pulmonary arteries, replacement of the morphologically tricuspid valve, and placement of pacemakers for third degree atrioventricular block. For many years, the classical approach was the “standard” surgical approach.1–4More recently, newer alternatives have become available, including forms of anatomic repair, the “one-and-a half” ventricular option, and conversion to the Fontan circulation. The goal of anatomic repair is to craft connections such that the morphologically left ventricle becomes the systemic ventricle. Surgical techniques that accomplish this are a Rastelli procedure combined with an atrial baffle,5and the combination of an arterial switch with an atrial baffle, be it a Mustard or Senning procedure.6

Abstract
A variety of surgical strategies have been utilized in attempts to accomplish long-term haemodynamic stability in patients with cardiac anomalies characterized by discordant atrioventricular connections, ventricular septal defect, and severe sub-pulmonary obstruction. The majority of these patients have what is commonly referred to as congenitally corrected transposition, together with a ventricular septal defect and pulmonary stenosis or atresia, in the setting of either usual or mirror imaged arrangement of the atrial chambers and the other organs of the body. A smaller sub-group, with discordant atrioventricular connections and double outlet right ventricle, with severe sub-pulmonary obstruction or pulmonary atresia, present similar physiology, and a comparable surgical challenge.
