Abstract
BACKGROUND Congenitally corrected transposition of the great arteries (CC-TGA) is a rare and complex form of congenital heart disease. Results of physiologic repair proved disappointing due to late right ventricular dysfunction and/or tricuspid regurgitation. The current study was performed to evaluate surgical outcomes in patients undergoing a double switch for CC-TGA. METHODS This was a retrospective review of 121 patients who underwent a double switch over a 2-decade time frame (2002-2023). Patients were a median age of 32 months. Before the double switch, 49 of 121 patients (40%) had undergone left ventricular retraining. RESULTS Sixty-seven patients underwent an arterial switch, and 54 underwent a Rastelli procedure. There were 4 in-hospital deaths (3.3%), including 3 who had a Rastelli procedure (5.6%) and 1 who had an arterial switch (1.5%). At a median follow-up of 30 months, there were 4 late deaths (2 Rastelli and 2 arterial switch). Combined early and late mortality was 9.3% for the Rastelli and 4.5% for arterial switch. Combined mortality was 2.0% for patients who required left ventricular retraining vs 9.7% for those who did not. For the 117 patients discharged from the hospital, 93% have normal or low-normal left ventricular function, and 96% have mild or less neoaortic insufficiency. CONCLUSIONS Surgical outcomes in patients undergoing a double switch procedure have been excellent both in the short- and midterm. However, the Rastelli procedure was associated with a more than 2-fold increase in mortality risk compared with the arterial switch.

Abstract
BACKGROUND Congenitally corrected transposition of the great arteries (CC-TGA) is a complex form of congenital heart disease that has numerous subtypes. While most patients with CC-TGA have a large ventricular septal defect (VSD) and pulmonary stenosis, there are some patients who have either no VSD or a highly restrictive VSD. These patients will require left ventricular (LV) retraining prior to double switch. The purpose of this study was to review our experience with the double switch procedure in patients who had previously undergone LV retraining. METHODS This was a retrospective review of a single institution experience with the double switch procedure in patients who had undergone LV retraining (2002-present). RESULTS Forty-five patients underwent double switch following LV retraining. Of these, 39 had an arterial switch with hemi-Mustard/bidirectional Glenn and six had a Senning. The median cross-clamp time was 135 min (range 71-272) and median bypass time was 202 min (range 140-430 min). Median hospital length of stay was eight days (range 4-108). There were no in-hospital deaths. Median duration of follow-up was 30 months (range 0-175). One patient subsequently underwent heart transplantation and died 65 months following double switch. At follow-up, 41 of the 44 survivors (93%) have normal or low normal LV function and 40 of the 44 survivors (91%) have no or trace mitral regurgitation. CONCLUSIONS The data demonstrate early and mid-term survival of 100% and 97%. Ninety-three percent had preserved LV function. These results suggest that patients with CC-TGA who undergo LV retraining and double switch can have excellent clinical outcomes.

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
A full-term, female presented on her date of birth with severe pulmonary hypertension (PH) and mitral regurgitation (MR), requiring veno-arterial extracorporeal membrane oxygenation. After the treatment, her PH and MR were resolved with no anatomic abnormality present. We propose a positive feedback loop of PH causing right ventricular dilation and interventricular septal shifts, worsening MR, and elevated left atrial, and potentially pulmonary, pressures.

Abstract
Patients with transposition of great arteries, with intact interventricular septum (TGA-IVS) and deconditioned left ventricle, represent a considerable challenge in developing countries. The modified Mustard operation was shown to provide a significant improvement for these patients, particularly by enhancing atrial functions and left ventricular filling. Yet, the problems of the systemic right ventricular dysfunction and the resulting secondary tricuspid regurgitation (TR) remain to be of major concern. In addition, the deviation of the interventricular septum towards the left side markedly impairs ventriculo-ventricular interaction and predisposes to dynamic left ventricular outflow tract obstruction (LVOTO). We report that adding a moderately loose pulmonary artery banding to the modified Mustard operation in a case of TGA-IVS results in improvement of biventricular geometry and function, tricuspid and mitral valve functions and disappearance of dynamic LVOTO.

Abstract
PURPOSE Congenitally corrected transposition of the great arteries (CC-TGA) is a complex form of congenital heart defect with numerous anatomic subgroups. The majority of patients with CC-TGA are excellent candidates for a double-switch procedure. However, in the absence of an unrestrictive ventricular septal defect or subpulmonary stenosis, the left ventricle (LV) may undergo involution and require retraining prior to double switch. The purpose of this study was to review our experience with patients having CC-TGA who required LV retraining prior to a double-switch procedure. METHODS This was a retrospective review of 24 patients with CC-TGA who were enrolled in an LV retraining program in preparation for a double-switch procedure. The median age at the time of enrollment for retraining was 11 months (range 1 month-24 years). The average left ventricle to right ventricle pressure ratio was 0.39 ± 0.07 prior to intervention. All 24 patients underwent placement of an initial pulmonary artery band (PAB) for LV retraining. RESULTS Eighteen (75%) of the 24 patients underwent a double-switch procedure with no operative mortality. Of these 18 patients, 9 had a single PAB and 9 required a second band for retraining. Six patients have not undergone a double-switch procedure to date. Five patients are good candidates for a double switch and are 2 weeks, 3 weeks, 4 weeks, 8 months, and 35 months since their last PAB. One patient died from a noncardiac cause 26 months after PAB retightening. The 18 patients who underwent a double switch were followed for an average of 5 ± 1 years (range 0.1-10.3 years). There has been no late mortality, and only 2 patients required further reinterventions. CONCLUSION The data demonstrate that LV retraining has been highly effective in this select group of patients with CC-TGA. The data also demonstrate that the results of the double-switch procedure have been excellent at midterm follow-up. These results suggest that LV retraining and double switch offer a reliable strategy option for patients with CC-TGA.

Abstract
BACKGROUND Transient preceding brief ischemia provides potent cardioprotection against subsequent long ischemia, termed ischemic preconditioning. Here, we hypothesized that transient short-term hypertrophic stimulation would induce the expression of hypertrophy regression genes and render the heart resistant to subsequent hypertrophic stress, and slow the progression to heart failure, as well. METHODS AND RESULTS Cardiomyocyte hypertrophy was induced in mice by either transverse aortic constriction or an infusion of phenylephrine, and in neonatal rat ventricular cardiomyocytes by norepinephrine exposures. In the preconditioning groups, hypertrophic stimulation was provided for 1 to 7 days and then withdrawn for several days by either aortic debanding or discontinuing phenylephrine or norepinephrine treatment, followed by subsequent reexposure to the hypertrophic stimulus for the same period as in the control group. One or 6 weeks after transverse aortic constriction, the heart weight/body weight ratio was lower in the preconditioning group than in the control group, whereas the lung weight/body weight ratio was significantly decreased 6 weeks after transverse aortic constriction. Similar results were obtained in mice receiving phenylephrine infusion and neonatal rat ventricular cardiomyocytes stimulated with norepinephrine. Both mRNA and protein expression of S100A8 and S100A9 showed significant upregulation after the removal of hypertrophic stimulation and persisted for 6 weeks in response to reimposition of transverse aortic constriction. The treatment with recombinant S100A8/A9 inhibited norepinephrine-induced myocyte hypertrophy and reduced the expression of calcineurin and NFATc3, but the silencing of S100A8/A9 prevented such changes. CONCLUSIONS Preconditioning with prohypertrophic factors exerts an antihypertrophic effect and slows the progression of heart failure, indicating the existence of the phenomenon for hypertrophic preconditioning.

Abstract
BACKGROUND Late referral of patients with transposition of the great arteries (TGA) and intact ventricular septum (IVS) is common in China. This study investigates the impact of later age on the arterial switch operation (ASO) performed for TGA-IVS beyond 1 month of age. METHODS From 2000 to 2011, a total 109 patients with TGA-IVS were referred over 1 month of age. In group A, 78 patients with satisfactory left ventricular (LV) geometry underwent a one-stage ASO. In group B, 31 patients with LV regression underwent a two-stage ASO with prior LV retraining. RESULTS The median age at ASO was older in group B (6 months, versus group A 1.9 months; p = 0.01). Group A had more frequent patent ductus arteriosus (70.5%, versus group B 38.7%; p = 0.02). The in-hospital mortality was similar in both groups (group A 2.6%, group B 9.7%; p = 0.14). Late mortality was higher in group B (16%, versus group A 2.7%; p = 0.03), as well as aortic regurgitation rate (group A 9.8% versus group B 33.3%; p = 0.01). The median duration of retraining in group B was 18 days. There were no deaths at retraining, although 2 patients required revision of the pulmonary artery banding. The only significant risk factor for late mortality in group B was age at retraining, as continuous variable (p = 0.04). Age beyond 3 months at LV retraining was associated with late impaired LV ejection fraction (p = 0.01). CONCLUSIONS The overall outcomes of ASO for TGA-IVS performed beyond 1 month of age are satisfactory. Two-stage ASO has higher late mortality and more neoaortic regurgitation. Later age at retraining is associated with higher late mortality. Age beyond 3 months at retraining is associated with impaired LV function.

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.

Abstract
Although there has been an intense interest in the care of the adult with congenital heart disease (ACHD), these guidelines are usually not focused on the concepts of immediate postoperative care. The 2 most common perioperative complications are heart failure and atrial dysrhythmias. The broad etiological categories for ACHD and heart failure include primary pump failure (systolic dysfunction) and hypertrophy (diastolic dysfunction) of the right, left, or single ventricle. Some conditions with a pressure-loaded systemic right ventricle as well as patients with a functionally single ventricle may be particularly prone to develop heart failure; in others, right heart failure may occur in patients with Ebstein anomaly or with tetralogy of Fallot after corrective repair but with varying degrees of pulmonary insufficiency, and left heart failure can be a result of mitral or aortic insufficiency. The management of postoperative atrial tachycardia in the ACHD patient actually begins prior to surgery. Assessment of arrhythmia history, complete determination of risk, inducibility and arrhythmia substrate, preoperative planning of pacing sites, and optimal pacing strategies all assist to bring about optimal postoperative outcomes. Ideal perioperative care of the ACHD involves a multidisciplinary team of pediatric and adult cardiologists, pediatric and adult intensivists, cardiac surgeons, and nursing staff along with a myriad of adult subspecialists such as pulmonology, nephrology, endocrinology, and others including psychiatry.

Abstract
In patients with congenitally corrected transposition of the great arteries, the main concern has been the long-term performance of the morphologic right ventricle in association with tricuspid valve regurgitation when it remains as the systemic ventricle. Deterioration in ventricular function can occur slowly over many years, even without associated cardiac anomalies or previous surgical interventions. This review summarizes the authors' experience and provides a thorough review of the literature addressing the management of the failing systemic right ventricle as well as the tricuspid valve regurgitation with congenitally corrected transposition. This includes different surgical options, the authors' preferred management algorithm, and the late outcome.

Abstract
BACKGROUND Early results for anatomic repair of congenitally corrected transposition of the great arteries are excellent with respect to right ventricular and tricuspid valve function. However, development of left ventricular (systemic ventricle) dysfunction late after repair remains a concern. In this study we sought to determine factors leading to late impairment in left ventricular performance. METHODS From August 1992 to July 2005, 44 patients (median age at surgery, 1.6 years; range, 0.6 to 39.6 years) with congenitally corrected transposition of the great arteries had anatomic repair. Left ventricular function and mitral regurgitation were evaluated by echocardiography at follow-up. Twenty-three patients had a Rastelli procedure, and 21 underwent an arterial switch. Twelve patients (27%) were pacemaker dependent at latest follow-up. RESULTS Early mortality was 4.5% (n = 2) with 1 late death as a result of leukemia. Median follow-up was 3.0 years (range, 7 days to 12.4 years). Left ventricular function remained unchanged (normal) in 35 patients, improved in 1 patient, and deteriorated in 8 patients (18%). Mitral regurgitation was unchanged in 30 patients, improved in 6 patients, and worsened in 8 patients (18%). Development of left ventricular dysfunction was significantly associated with pacemaker implantation (p = 0.005) and a widened QRS (>20% > 98% percentile of normal; p = 0.03). CONCLUSIONS Anatomic repair of congenitally corrected transposition can be performed with low operative mortality. However, late left ventricular dysfunction is not uncommon, with higher incidence in those requiring pacing and with a prolonged QRS. Resynchronization may be of value in patients requiring a pacemaker.

Abstract
Conditions in which the right ventricle serves as the systemic pumping chamber are frequently complicated by the development of right ventricular failure and tricuspid valve regurgitation. The right ventricle is the systemic ventricle in conditions of ventriculoarterial discordance with atrioventricular concordance (transposition of the great arteries) or with atrioventricular discordance (congenitally corrected transposition of the great arteries). Concerns regarding actual or potential systemic right ventricular failure in these cases may lead to surgical evaluation and treatment designed to reestablish the left ventricle as the systemic pump. In cases where the left ventricle has prolonged exposure to low pressures in the pulmonary circulation, the left ventricle must be "retrained" to assume a systemic pressure load. Anatomic repair, with or without a preparatory period of left ventricular retraining, is a consideration for three clinically relevant scenarios: (1) patients with transposition of the great arteries after an atrial level switch (Senning or Mustard procedure), (2) patients with congenitally corrected transposition who are unoperated or who have undergone physiologic ("classic") repair, and (3) unoperated patients with transposition who present after the neonatal period.

Abstract
In congenitally corrected transposition (ccTGA) the most common configuration is atrial situs solitus with left ventricular loop and left transposition of the great arteries (SLL). Less common is ccTGA with atrial siti inversus (IDD). In both configurations there is a high incidence of ventricular septal defect, pulmonary stenosis, or atresia and some anatomic abnormality of the morphologic tricuspid valve (mTV). The morphologic right ventricle (mRV) is the systemic ventricle and prone to premature failure, particularly in the presence of early TV regurgitation, atrial arrhythmias conduction defects, and prior surgical ventricular septal defect closure. With a long experience with the Senning operation and then the arterial switch, it seemed feasible that these could be combined in ccTGA to restore the mLV to the systemic circuit. This was first attempted in 1989 by the author and was successful. Many of the more recently graduated congenital heart surgeons have little or no experience with the inflow switch. For this reason, the author was asked to write this article, accenting the technical details of the inflow switch. The author uses the Senning operation, with those modifications needed to accommodate the differences between the morphologic right atrium, conduction system, and quite frequent discordance between the atrial situs and the position of the apex of the heart, in ccTGA as compared with TGA.

Abstract
OBJECTIVES Systemic right ventricular failure after atrial switch procedures for transposition of the great arteries has been addressed at Melbourne's Royal Children's Hospital (1981-1993) and the Cleveland Clinic Foundation (1993-2001) with reconditioning of the morphologically left ventricle by means of pulmonary artery banding followed by an arterial switch operation and an atrial reseptation. METHODS Thirty-nine patients (Royal Children's Hospital, 19; Cleveland Clinic Foundation, 20) with a median age of 10.8 years (range, 13 months-24 years) entered this protocol a median of 10.3 years (range, 0.5-24 years) after an atrial switch procedure. RESULTS The median duration of pulmonary artery banding was 13 months (range, 0.5-5.4 years). Ten (28%) patients responded unfavorably to morphologically left ventricular reconditioning (5 mortalities: 4 transplantations and 1 PAB still in place). Twenty-four (83%) of the 29 patients who underwent an atrial switch operation and atrial reseptation survived. During a median follow-up period of 8.2 years (range, 1-16 years), 3 patients had cardiac-related deaths. All 18 long-term survivors are asymptomatic. At last echocardiographic evaluation, the morphologically left ventricular function was normal or mildly decreased in 16 (89%) patients, and all had normal or mildly decreased systemic right ventricular function with no or mild tricuspid regurgitation. Age greater than 12 years was associated with a greater probability of morphologically left ventricular failure and not completing the protocol (P =.02) and a higher operative mortality at anatomic correction (P =.02). CONCLUSIONS Morphologically left ventricular reconditioning and an anatomic correction protocol should be integrated into a cardiac transplantation program when treating patients with morphologically right ventricular failure after Mustard and Senning procedures. It is an alternative to cardiac transplantation in selected patients, with good long-term results. The response to morphologically left ventricular reconditioning past adolescence is inconsistent.

Abstract
OBJECTIVE An experimental model with a reversible pulmonary trunk banding device was developed with the aim of inducing rapid ventricular hypertrophy. The device consists of an insufflatable cuff connected to a self-sealing button. METHODS The right ventricles of 7 young goats (average weight, 8.7 kg) were submitted to systolic overload and evaluated according to the hemodynamic, echocardiographic, and morphologic aspects. Baseline biopsy specimens were taken from the myocardium for microscopic analysis. The device was implanted on the pulmonary trunk and inflated so that a 0.7 right ventricular/left ventricular pressure ratio was achieved. Echocardiographic and hemodynamic evaluations were performed every 24 hours. Systolic overload was maintained for 96 hours. The animals were then killed for morphologic study. Another 9 goats (average weight, 7.7 kg) were used for control right ventricular weight. RESULTS The systolic right ventricular/pulmonary trunk pressure gradient varied from 10.1 +/- 4.3 mm Hg (baseline) to 60.0 +/- 11.0 mm Hg (final). Consequently, the right ventricular/left ventricular pressure ratio increased from 0.29 +/- 0.06 to 1.04 +/- 0.14. The protocol group showed a 74% increase in right ventricular mass when compared with the control group. Serial 2-dimensional echocardiography showed a 66% increase in right ventricular wall thickness. There was a 24% increase in the mean myocyte perimeter, and the myocyte area increased 61%. CONCLUSIONS The device is easily adjustable percutaneously, enabling right ventricular hypertrophy in 96 hours of gradual systolic overload. This study suggests that the adjustable pulmonary trunk banding might provide better results for the 2-stage Jatene operation and for the failed atrial switch operations to convert to the double-switch operation.

Abstract
BACKGROUND The conventional treatment of transposition of great arteries with prepared left ventricle is an arterial switch operation. This, in our experience, does not hold for patients with transposition of great arteries with intact ventricular septum where the left ventricle continues to be prepared secondary to severe pulmonary arterial hypertension without an immediately reversible cause. METHODS Ten infants with D-transposition of the great arteries with essentially intact interventricular septum and severe pulmonary arterial hypertension underwent surgical treatment. Age ranged from 3 to 6 months (mean, 4.2 months). One of these patients had a large ductus with left to right shunting but the others had no intra- or extracardiac shunt to account for their pulmonary hypertension. All 10 had "prepared" left ventricles. The first 4 children underwent an arterial switch operation. Uneventful surgery was followed by prolonged ventilator dependence in all 4 with occurrence of severe pulmonary arterial hypertension every time weaning from ventilator was attempted. This was accompanied by metabolic acidosis and features of right heart failure. Only 1 patient with large ductus could be extubated and discharged from hospital. Subsequently, the other 6 infants underwent a Senning repair. RESULTS There was no early mortality. All patients were separated from mechanical ventilation within 48 hours of surgery without blood gas derangement or heart failure despite elevated pulmonary artery pressure in all. The child with the arterial switch operation has pulmonary artery pressure of 50% systemic 4 years following repair; although among the Senning group, 2 patients continue to have pulmonary artery pressure more than 60% of systemic and 4 have normal pulmonary artery pressure at a mean follow-up of 1 year. CONCLUSIONS Atrial level repairs seem to perform better than arterial level repairs in children having TGA with persistent pulmonary artery hypertension without a correctable cause. Better tolerance of pulmonary arterial hypertension in this group is probably consequent to the superior ability of the left ventricle to tolerate a pressure load in the early postoperative period.

Abstract
BACKGROUND The mortality of pulmonary artery banding improved significantly in the 1980s. However, we lack information on this procedure in the current era. METHODS The results of pulmonary artery banding in 365 patients who had operations between 1966 and 2001 were reviewed. The patients were divided into three groups: (1) group 1 patients who had operations between 1966 and 1979, (2) group 2 patients who had operations between 1980 and 1989, and (3) group 3 patients who had operations between 1990 and 2001. RESULTS Significantly younger and smaller patients have been operated on recently (mean age: group 1, 169.0 +/- 40 days; group 2, 101.8 +/- 11 days; and group 3, 69.7 +/- 8.9 days; and mean weight: 4.6 +/- 0.1, 4.1 +/- 0.1, and 3.2 +/- 0.1 kg, respectively). A decrease was found in the number of simple cardiac anomalies, such as isolated ventricular septal defects. The early mortality in the three groups was 38.3% for group 1 (65 of 187), 13.5% for group 2 (15 of 111), and 13.8% for group 3 (12 of 87). Although the mortality did not vary significantly between groups 2 and 3, it improved over time in patients weighing less than 3 kg. Multivariate analysis of group 3 demonstrated that no isolated variable, including sex, weight, and diagnosis was a significant risk factor. CONCLUSIONS Despite the advances in perioperative management, we found no improvement in the early mortality of pulmonary artery banding during the last decade. These results will support the preference for primary repair of intracardiac anomalies in small infants. However, this operation can now be performed with the same risk even in smaller patients. We believe that pulmonary artery banding has a role in the treatment of congenital cardiac anomalies.
