Abstract
Surgical treatment for congenitally corrected transposition of the great arteries is widely debated, with both physiologic repair and anatomic repair holding advantages and disadvantages. This meta-analysis, which includes 44 total studies consisting of 1857 patients, compares mortality at different time points (operative, in-hospital, and post-discharge), reoperation rates, and postoperative ventricular dysfunction between these two categories of procedures. Although anatomic and physiologic repair had similar operative and in-hospital mortality, anatomic repair patients had significantly less post-discharge mortality (6.1% vs 9.7%; P = .006), lower reoperation rates (17.9% vs 20.6%; P < .001), and less postoperative ventricular dysfunction (16% vs 43%; P < .001). When anatomic repair patients were subdivided into those who had atrial and arterial switch versus those who had atrial switch with Rastelli, the double switch group had significantly lower in-hospital mortality (4.3% vs 7.6%; P = .026) and reoperation rates (15.6% vs 25.9%; P < .001). The results of this meta-analysis suggest a protective benefit of favoring anatomic repair over physiologic repair.

Abstract
Current guidelines for adults with atrial switch repair recommend baseline cardiovascular magnetic resonance (CMR) for assessment of ventricular size and function, systemic and venous baffle obstruction and leaks, and valvular function. It also recommends transthoracic echocardiography (TTE) for outpatient follow up. Many such patients with implanted cardiac devices may need cardiac computed tomography (CCT) when CMR is not feasible. This study reviews and compares CMR, transesophageal echocardiography (TEE), CCT, cardiac catheterization with angiography and TTE in detection of baffle problems in patients after atrial switch operation. The medical records of patients who had at least one imaging study performed after atrial switch operation at our center from 2010 to 2020 were retrospectively reviewed. Results are reported as descriptive statistics for demographics and imaging findings. The principal outcome measure was detection of baffle leak and/or baffle stenosis. Fifty-seven patients had at least one cardiac imaging study after atrial switch operation (36 Senning and 21 Mustard operations) during the study period. Nearly 33% (19/57) had baffle complications of stenosis and/or baffle leaks identified. All 57 patients had TTE performed but baffle problems were noted by TTE in only 8 (14%) patients (7 baffle stenosis and 1 baffle leak). Of the 49 patients without known baffle problems by TTE, 24 had advanced imaging (TEE/CCT/CMR/angiography). Advanced imaging identified baffle problems in nearly half (11/24, 46%) of them (7 baffle leaks and 4 baffle stenosis). Baffle problems were present in (8/23) patients with transvenous cardiac devices. Baffle complications are common after atrial switch operations and in our study occur in 1/3rd of the patients. However, TTE is not sensitive enough to recognize these complications. Advanced imaging for detection of baffle complications should be considered in all patients after atrial switch operation.

World J Cardiol 2020; 12:427-436. [PMID: 32879705 PMCID: PMC7439449 DOI: 10.4330/wjc.v12.i8.427] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 06/08/2020] [Accepted: 07/19/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Treatment of congenitally corrected transposition of great arteries (cc-TGA) with anatomic repair strategy has been considered superior due to restoration of the morphologic left ventricle in the systemic circulation. However, data on long term outcomes are limited to single center reports and include small sample sizes.
AIM To perform a systematic review and meta-analysis for observational studies reporting outcomes on anatomic repair for cc-TGA.
METHODS MEDLINE and Scopus databases were queried using predefined criteria for reports published till December 31, 2017. Studies reporting anatomic repair of minimum 5 cc-TGA patients with at least a 2 year follow up were included. Meta-analysis was performed using Comprehensive meta-analysis v3.0 software.
RESULTS Eight hundred and ninety-five patients underwent anatomic repair with a pooled follow-up of 5457.2 patient-years (PY). Pooled estimate for operative mortality was 8.3% [95% confidence interval (CI): 6.0%-11.4%]. 0.2% (CI: 0.1%-0.4%) patients required mechanical circulatory support postoperatively and 1.7% (CI: 1.1%-2.4%) developed post-operative atrioventricular block requiring a pacemaker. Patients surviving initial surgery had a transplant free survival of 92.5% (CI: 89.5%-95.4%) per 100 PY and a low rate of need for pacemaker (0.3/100 PY; CI: 0.1-0.4). 84.7% patients (CI: 79.6%-89.9%) were found to be in New York Heart Association (NYHA) functional class I or II after 100 PY follow up. Total re-intervention rate was 5.3 per 100 PY (CI: 3.8-6.8).
CONCLUSION Operative mortality with anatomic repair strategy for cc-TGA is high. Despite that, transplant free survival after anatomic repair for cc-TGA patients is highly favorable. Majority of patients maintain NYHA I/II functional class. However, monitoring for burden of re-interventions specific for operation type is very essential.

Abstract
BACKGROUND Optimal management of patients with congenitally corrected transposition of the great arteries (ccTGA) is unclear. The goal of this study was to compare the outcomes in patients with ccTGA undergoing different management strategies. STUDY DESIGN Patients with ccTGA believed suitable for biventricular circulation, treated between 1995 and 2016, were included. The cohort was divided into 4 groups: systemic right ventricle (RV) (patients without surgical intervention or with a classic repair), anatomic repair, Fontan palliation, and patients receiving only a pulmonary artery band (PAB) or a shunt. Transplant-free survival from presentation was calculated for each group. RESULTS The cohort included 97 patients: 45 (46%) systemic RV, 26 (27%) anatomic repair, 9 (9%) Fontan, and 17 (18%) PAB/shunt. Median age at presentation was 2 months (range 0 days to 69 years) and median follow-up was 10 years (1 month to 28 years). At initial presentation, 10 (11%) patients had any RV dysfunction (8 mild, 2 severe), and 16 (18%) patients had moderate or severe tricuspid regurgitation (TR). During the study, 10 (10%) patients died, and 3 (3%) patients underwent transplantation. At last follow-up, 11 (11%) patients were in New York Heart Association class III/IV, 5 (5%) had moderate or severe systemic ventricle dysfunction, and 16 (16%) had moderate or severe systemic atrioventricular valve regurgitation. Transplant-free survivals at 10 years were 93%, 86%, 100%, and 79% for systemic RV, anatomic repair, Fontan palliation, and PAB/shunt, respectively (p = 0.33). On multivariate analysis, only systemic RV dysfunction was associated with a higher risk for death or transplant (p = 0.001). CONCLUSIONS Transplant-free survival in ccTGA appears to be similar between patients with a systemic RV, anatomic repair, and Fontan procedure. Systemic RV dysfunction is a risk factor for death and transplant.

Abstract
The atrial switch operation with the Rastelli procedure is becoming popular for treatment of the subgroup of corrected transposition of the great arteries with ventricular septal defect and pulmonary obstruction. This technique eliminates the problem of short- and long-term right ventricular failure, and decreases the incidence of iatrogenic atrioventricular heart block. Between April 2001 and November 2002, this technique was used in 3 patients aged 5 to 7 years. Two had a Senning operation and one had a Mustard operation. There was no operative death. The first patient needed re-operation to close the sternum. The last patient was re-explored for bleeding. All patients were in New York Heart Association functional class I at their last follow-up. The atrial switch plus Rastelli procedure is feasible in this subgroup of corrected transposition, but longer follow-up is necessary to determine whether this approach is indeed warranted.

Abstract
The survival of patients with congenital heart diseases (CHD) has increased in the past decades, resulting in the identification of new characteristics of chronic comorbidities observed in pediatric and adults with CHD. Patients with CHD can present with a broad clinical spectrum of manifestations of congestive heart failure (CHF) at any point throughout their lives that may be related to anatomical or surgical variables. This article focuses on the perioperative assessment of patients with CHD and CHF, with an emphasis on pathophysiologic, diagnostic, and therapeutic alternatives in patients with right ventricular failure and failing Fontan circulation. We also provide descriptions of the effects of sedatives and anesthetics commonly used in this population in diagnostic or invasive procedures.

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
BACKGROUND We investigated the long-term outcomes of anatomic repair for congenitally corrected transposition of great arteries (ccTGA) and its variant associated with left ventricular outflow tract obstruction (LVOTO) and ventricular septal defect (VSD). METHODS From 1987 to 2011, 47 patients (27 with pulmonary atresia and 20 with pulmonary stenosis) with ccTGA and its variant associated with LVOTO and VSD underwent anatomic repair. The mean operative age was 5.5 ± 3.7 years old (range, 1.6 to 21.3). The preoperative right ventricular end-diastolic volume was 133% ± 31% (81 to 222) of their normal size. The atrial switch procedure was Mustard in 31 patients and Senning in 16, with the latter used in all from 2002. RESULTS The mean follow-up period was 11.6 ± 7.3 years (maximum, 22.7). The VSD was concomitantly enlarged in 4 patients and Damus-Kaye-Stansel (DKS) anastomosis was added in 9 patients with pulmonary stenosis and restrictive VSD. The overall survival rate at 20 years was 70.2% and no mortality has been observed in 21 consecutive patients since 1997. No patient required reoperation for the postoperative systemic ventricular outflow tract obstruction. A surgical heart block developed in 1 patient (2.1%) who underwent concomitant VSD enlargement. None of the patients developed a moderate or greater aortic or neo-aortic regurgitation. CONCLUSIONS Recent outcomes after anatomic repair for congenitally corrected transposition of great arteries associated with LVOTO and VSD were excellent. For patients with pulmonary stenosis and restrictive VSD, additional DKS anastomosis seems to be an effective approach to avoid postoperative systemic ventricular outflow tract obstruction and surgical heart block.

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.

Malhotra SP, Reddy VM, Qiu M, Pirolli TJ, Barboza L, Reinhartz O, Hanley FL. The hemi-Mustard/bidirectional Glenn atrial switch procedure in the double-switch operation for congenitally corrected transposition of the great arteries: rationale and midterm results. J Thorac Cardiovasc Surg 2010; 141:162-70. [PMID: 21055773 DOI: 10.1016/j.jtcvs.2010.08.063] [Citation(s) in RCA: 55] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2010] [Revised: 08/03/2010] [Accepted: 08/29/2010] [Indexed: 11/17/2022]
Abstract
OBJECTIVE This study was undertaken to assess the risks and benefits of the double-switch operation using a hemi-Mustard atrial switch procedure and the bidirectional Glenn operation for congenitally corrected transposition of the great arteries. To avoid complications associated with the complete Senning and Mustard procedures and to assist right-heart hemodynamics, we favor a modified atrial switch procedure, consisting of a hemi-Mustard procedure to baffle inferior vena caval return to the tricuspid valve in conjunction with a bidirectional Glenn operation. METHODS Between January 1994 and September 2009, anatomic repair was achieved in 48 patients. The Rastelli-atrial switch procedure was performed in 25 patients with pulmonary atresia and the arterial-atrial switch procedure was performed in 23 patients. A hemi-Mustard procedure was the atrial switch procedure for 70% (33/48) of anatomic repairs. RESULTS There was 1 in-hospital death after anatomic repair. There were no late deaths or transplantation. At a median follow-up of 59.2 months, 43 of 47 survivors are in New York Heart Association class I. Bidirectional Glenn operation complications were uncommon (2/33), limited to the perioperative period, and seen in patients less than 4 months of age. Atrial baffle-related reoperations or sinus node dysfunction have not been observed. Tricuspid regurgitation decreased from a mean grade of 2.3 to 1.2 after repair (P = .00002). Right ventricle-pulmonary artery conduit longevity is significantly improved. CONCLUSIONS We describe a 15-year experience with the double-switch operation using a modified atrial switch procedure with favorable midterm results. The risks of the hemi-mustard and bidirectional Glenn operation are minimal and are limited to a well-defined patient subset. The benefits include prolonged conduit life, reduced baffle- and sinus node-related complications, and technical simplicity.

Abstract
Aim of the study To investigate the long-term outcome of surgical treatment for congenitally corrected transposition of the great arteries (CCTGA), in patients with biventricular repair with the right ventricle as systemic ventricle. Methods A total of 32 patients with CCTGA were operated between January 1972 and October 2008. These operations comprised 18 patients with a repair with a normal left ventricular outflow tract, 11 patients with a Rastelli repair of the left ventricle to the pulmonary artery and 3 patients with a cardiac transplantation. Results Excluding the cardiac transplantation patients, mean age at operation was 16 years (sd 15 years, range 1 week - 49 years). Median follow-up was 12 years (sd 10 years, range 7 days - 32 years). Survival obtained from Kaplan-Meier analysis at 20 years after surgery was 63% (CI 53-73%). For the non-Rastelli group these data at 20 years were 62% (CI 48-76%) and for the Rastelli group 67% (CI 51-83%). Freedom of reoperation at 20 years was 32% (CI 19-45%) in the overall group. In the non-Rastelli group the data at 20 years were 47% (CI 11-83%) and for the Rastelli group 21% (CI 0-54%) after almost 19 years. Conclusions Long term follow up confirms that surgery in CCTGA with the right ventricle as systemic ventricle has a suboptimal survival and limited freedom of reoperation. Death occurred mostly as a result of cardiac failure.

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
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
OBJECTIVE This study was undertaken to compare long-term results of various types of surgical repairs for either congenitally corrected transposition of the great arteries or double outlet right ventricle with discordant atrioventricular connections, and to analyze the risk factors that affect early and late mortality and reintervention. METHODS Between January 1972 and September 2005, a total of 189 patients (median age 8.3 years, range 2 months to 47 years old) with congenitally corrected transposition of the great arteries or double outlet right ventricle with discordant atrioventricular connections underwent definitive repairs. The definitive repairs comprised a conventional repair (atrial septal defect, or ventricular septal defect closure with or without pulmonary stenosis release, or isolated tricuspid valve surgery) in 36 patients (group I), conventional Rastelli in 31 patients (group II), double-switch operation (atrial switch plus arterial switch) in 15 patients (group III), atrial switch plus intraventricular rerouting (with or without extracardiac conduits) in 69 patients (group IV), and a Fontan-type repair in 38 patients (group V). The mean follow-up period was 10.1 years. Hospitalization and late mortality and reoperation were indicated as events. Risk factors for these events were analyzed by logistic regression for hospital death and a Cox proportional hazards model for late events. RESULTS The Kaplan-Meier survival including hospital and late mortality was 62.4% at 32 years in group I, 78.5% at 27 years in group II, 74.5% at 15 years in group III, 80% at 16 years in group IV, and 79.3% at 22 years in group V. The reoperation-free ratio was 64.2% in group I, 76.6% in group II, 84.4% in group III, 89.6% in group IV, and 91.3% in group V. Risk analyses showed that the risk for hospital death was preoperative in patients with more than moderate tricuspid regurgitation and a cardiopulmonary bypass time of more than 240 minutes. A risk for late mortality was the presence of tricuspid regurgitation. Risks for reoperation were preoperative cardiomegaly, preoperative tricuspid regurgitation of more than grade II, ventricular septal defect enlargement, and body weight less than 10 kg. Risks for pacemaker implantation, as indicated by multivariate analysis, were ventricular septal defect enlargement during operation and age less than 3 years. CONCLUSIONS There were no statistical differences between long-term survival rates of patients who underwent conventional surgical repair versus those of patients who underwent anatomic surgical repair. Results of conventional repair were satisfactory except in patients with significant tricuspid regurgitation. Results of anatomic repair were also satisfactory even for patients with significant tricuspid regurgitation, and therefore, anatomic repair should be the procedure of choice for those patients.

Abstract
BACKGROUND In patients with discordant atrioventricular and ventriculoarterial connections, anatomic repair restores the morphologically left ventricle to its role in supporting the systemic circulation. In this study, we have evaluated the outcomes in the intermediate term for this complex surgical procedure. METHODS Between December 1984 and October 2003, 4 patients underwent an atrial switch operation concomitantly with a Rastelli operation, and 2 patients underwent an atrial switch operation and a patch-plasty of the pulmonary outflow tract for anatomic repair at a mean age of 3.3 plus or minus 2.1 years. All patients had intracardiac rerouting, connecting the morphologically left ventricle to the aorta. RESULTS There were no hospital deaths. In 5 patients, reoperation was needed, either for baffle complications, exchange of the conduit, repair of a residual ventricular septal defect, or relief of obstruction within the left ventricular outflow tract. Death occurred in 1 patient, from cardiac failure 6 months after correction. Mean follow-up time was 6.5 plus or minus 6.4 years, with a range from 6 months to 17 years. At follow-up, 1 patient presented with moderate tricuspid insufficiency, and 1 patient with mild obstruction of the pulmonary venous pathway. The remaining 3 patients showed good left and right ventricular function, and no, or mild tricuspid and mitral insufficiency. CONCLUSIONS Anatomic repair can be performed with low hospital mortality. Restoration of the morphologically left ventricle into the systemic circulation in patients with discordant atrioventricular and ventriculoarterial connections is a demanding approach, associated with various reoperations over time. Despite this, the approach seems to be an appropriate solution for selected patients, since the majority of the patients show good left and right ventricular function, and no, or mild tricuspid and mitral insufficiency up to 17 years after correction.

Abstract
Left ventricular (LV) retraining followed by anatomical repair would be a superior alternative in patients with congenitally corrected transposition (ccTGA) having a deconditioned morphologically left ventricle (MLV); however, LV retraining in older children is a challenging task. A retraining process of the MLV in a teenage patient with ccTGA is reported here. Cardiac catheterization at 7 years of age revealed low pressure of the MLV (33/4 mm Hg) and a LV to right ventricular pressure ratio (LVp/RVp ratio) of 0.32. The first pulmonary artery banding (PAB) was performed at 10 years of age. Although the LVp/RVp ratio reached 0.68, there was no evidence of adequate LV hypertrophy. The second PAB was performed 2 years after the initial PAB, resulting in an increase in the LVp/RVp ratio to 0.93 and an adequate LV hypertrophy. The double switch procedure was successfully performed at 13 years of age. Although the ejection fraction of the MLV mildly decreased, the patient has been doing well during a follow-up period of 4 years. The MLV in the teenage patient with ccTGA was successfully trained using a retraining strategy and has sustained systemic circulation after anatomical repair.

Abstract
We evaluated exercise tolerance and cardiorespiratory responses to exercise in patients with atrioventricular discordance (AVD) and abnormal ventriculoarterial connection after anatomic repair. Cardiopulmonary treadmill exercise testing with gas measurement was done 62 times in 19 patients with AVD who had undergone anatomic repair at the National Cardiovascular Center. Exercise duration, oxygen uptake (V(O2)) and heart rate at anaerobic threshold and peak, and oxygen pulse during exercise were significantly lower in patients with AVD after anatomic repair than in controls. Carbon dioxide ventilatory equivalent during exercise was worse in patients with AVD after anatomic repair than in controls. Percentage peak V(O2) significantly correlated positively with percentage peak oxygen pulse and tended to correlate positively with the heart rate increments. Patients with AVD after anatomic repair exhibit impaired responses of heart rate and oxygen pulse with lower exercise capacity. Careful attention should be paid to patients with AVD after anatomic repair in terms of their functional capacity as well as other postoperative complications.

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
The congenital cardiac malformation characterized by discordant connections between the atriums and ventricles, as well as those between the ventricles and the arterial trunks, has been given many names. The terms atrioventricular discordance, l-transposition of the great arteries, ventricular inversion, and congenitally corrected transposition have all been used. Regardless of terminology, this complex congenital anomaly has only recently been studied to analyze the long-term effects of its natural history and outcomes following traditional surgical repair of the associated malformations which serve to uncorrect the circulatory pathways. As more patients survive into adulthood, the effects of this condition are now better understood, and the surgical approaches used in the past are being re-examined in light of longer-term follow up.

Abstract
The objective of this meta-analysis of individual patients' data was to compare the immediate outcomes of anatomic and physiologic repair of congenitally corrected transposition of the great arteries. Eleven nonrandomized studies, involving 124 patients, met the inclusion criteria for this review. The Rastelli type anatomic repair and the era of surgery were significantly related to the outcome in different tested models. Entering all variables into the logistic regression model showed a significant protective effect of the Rastelli type anatomic repair (odds ratio = 0.05, 95% confidence interval: 0.01, 0.50, p = 0.02).

Abstract
We describe a case of congenitally corrected transposition of the great arteries (cc-TGA) successfully performed by the double switch operation after two-staged pulmonary artery banding (PAB). An eleven-year old boy diagnosed with cc-TGA underwent the first PAB at that age, followed by the second PAB one year later. Because of severe ventricular dysfunction and arrhythmia of the anatomic left ventricle, the intension of one-stage PAB was abandoned. Cardiac catheterization data from after the adequate second PAB provided the surgical indication for the anatomical correction and double switch operation (Senning+Jatene procedure) and this was successfully performed at age 14. Although cardioversion was required to treat supraventricular tachycardia in the early period after surgery, the patient was discharged from hospital and remains in good clinical condition at the last follow-up at 5 years with normal sinus rhythm and good biventricular function.

Abstract
BACKGROUND Since 1987, anatomic biventricular repair using the double-switch operations has been our principal choice for patients with atrioventricular discordance. These alternative procedures have the theoretical advantage of using the anatomic left ventricle to support the systemic circulation. METHODS A total of 45 patients underwent the double-switch operation. Their ages ranged from 6 months to 21 years. Associated malformations included pulmonary atresia in 27, pulmonary stenosis in 11, and Ebstein's malformation in 5. An atrial switch plus an arterial switch procedure was performed in 7, and an atrial switch plus a Rastelli-type ventriculoarterial switch procedure in 38. Follow-up ranged from 6 months to 15 years. RESULTS Early mortality was 8.9% (n = 4). In the latter half of the series (n = 23, since 1994), there was no early death. Six patients died late. Actuarial survival at 5 and 10 years was 83.6% and 77.6%, respectively. Six patients required conduit replacement, and 2 required revision of an intraatrial baffle for pulmonary venous channel obstruction and infection, respectively. Freedom from reoperation was 95.3% at 5 years and 76.2% at 10 years. Freedom from arrhythmia was 88.8% at 5 years and 78.4% at 10 years. The systemic ventricular ejection fraction was 0.568 +/- 0.103 at 1 year (n = 39), 0.555 +/- 0.105 at 5 years (n = 17), and 0.539 +/- 0.098 at 10 years (n = 12). CONCLUSIONS The surgical results of the double-switch operations have been improving. Intermediate follow-up suggests that these alternative procedures are a reasonable option for patients with atrioventricular discordance.

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
Conventional surgery for atrioventricular discordance usually associated with ventricular arterial discordance leaves the morphologic right ventricle in the systemic circulation. Long-term follow-up results with this approach reveal a high incidence of right ventricular failure. The double switch procedure was introduced to restore the morphologic left ventricle to the systemic circulation. This operation is performed in two main ways: the atrial-arterial switch and the atrial switch plus Rastelli procedure. This double switch approach has been successful at least in the medium term in abolishing morphologic right ventricular failure and its associated tricuspid valve regurgitation. In the atrial-arterial switch group, there is an incidence of morphologic left ventricular dysfunction, sometimes associated with neoaortic valve regurgitation, and the minority of cases need aortic valve replacement. The long-term function of the morphologic left ventricle and the aortic valve need careful surveillance in the future. The atrial-Rastelli group of patients has not in the medium term shown evidence of ventricular dysfunction but will require change on a regular basis of their ventricular to pulmonary artery valved conduits.

Abstract
Based on experience in several centers, the double switch operation has reportedly become the standard surgical therapy for congenitally corrected transposition. We report and discuss here the use of a "ventricle and a half" double switch operation performed due to the concerns raised intraoperatively because of the size of the morphologically right ventricle. Although the long-term course of such a procedure in this setting remains unknown, we submit that the proposed benefits of the double switch operation, even when used in the "ventricle and a half" configuration, may be superior to the alternatives.

Abstract
Congenitally corrected transposition of the great arteries is a relatively rare cardiac malformation characterized by atrioventricular and ventriculoarterial discordance. This double discordance results in a physiologically corrected circulation with the morphologic right ventricle (RV) serving as the systemic pump. Associated anomalies are present in approximately 98% of cases and include most commonly ventricular septal defect, pulmonary stenosis, and anomalies of the systemic atrioventricular valve (SAVV). Conduction abnormalities are common as well, predisposing these patients to the development of complete heart block. The management of these patients is primarily determined by the presence and severity of the associated anomalies. Conventional repair, which leaves the morphologic RV as the systemic ventricle, has resulted in high incidence of tricuspid regurgitation (TR) and progressive dysfunction of the RV. In the majority of patients, congestive heart failure secondary to RV dysfunction occurs by the fifth or sixth decade. The cause and effect relationship between TR and RV dysfunction remains to be determined. The advent of the Double Switch operation, which restores the morphologic left ventricle (LV) as the systemic ventricle, has yielded favorable outcomes at early follow-up. This procedure should be applied in young patients to achieve optimal results. Retraining the LV by pulmonary artery banding is associated with high morbidity and mortality when attempted after infancy or early childhood. Long-term follow-up is needed to evaluate the potential superiority of this procedure and the incidence of rhythm, baffle, and conduit complications for this management option.

Abstract
OBJECTIVE Evaluation of incremental risk factors for early mortality in children undergoing orthotopic heart transplantation (OHT) for congenital heart disease. METHODS Between 1988 and 2002, 43 patients (mean age 9.1+/-7.2 years) underwent 44 OHT for complex TGA (6), DORV (4), single ventricle (21), and other end-stage structural heart disease (11). Two discernible ventricular chambers were present in 18 pts (41.8%). Previous reconstructive or palliative procedures had been previously accomplished in 35 pts (83.3%), including atrial switch (5), systemic-to-pulmonary shunts (10), cavopulmonary anastomosis (9), Fontan completion (6), and others (5). RESULTS 30-day survival for the 2-ventricle subgroup was 94.4+/-5.4% compared with 67.2+/-9.5% for the single ventricle subgroup (P=0.04) (overall 78.6%+/-3.3%). OHT following single ventricle staging to bi-directional cavopulmonary anastomosis exhibited 100% early survival, as opposed to 62.5+/-17.1% for OHT after systemic-to-pulmonary shunts, and 33.3+/-19.2% for OHT following failing Fontan (P=0.010). HLHS diagnosis (0.0085) and failing Fontan (P=0.003) were identified as independent predictors of early mortality by regression logistic modeling, while Fontan stage represented the only predictor of overall mortality by Cox proportional hazard. Overall 10-year survival was 54.3+/-11%. CONCLUSIONS OHT for structural congenital heart disease with single ventricle physiology entails substantial early mortality and bi-directional cavopulmonary anastomosis enables the best transition to heart transplant. OHT should be considered in the decision making process as an alternative to Fontan completion in high-risk candidates, since rescue-OHT after failing Fontan seems unwarranted.

Abstract
OBJECTIVE This study was undertaken to determine the outcomes of patients with congenitally corrected transposition of the great arteries after restoration of the morphologically left ventricle to the systemic circulation. METHODS Between November 1991 and June 2001, a total of 54 patients (median age 3.2 years, range 7 weeks-40 years) with either congenitally corrected transposition of the great arteries (n = 51) or atrioventricular discordance with double-outlet right ventricle (n = 3) underwent anatomic repair. This comprised a Senning procedure in all cases plus arterial switch (double-switch group) in 29 cases (53.7%), plus a Rastelli procedure (Rastelli-Senning group) in 22 cases (40.7%), and plus intraventricular rerouting (Senning-tunnel group) in 3 cases (5.6%). Left ventricular training by PA banding was performed before the double-switch operation in 9 of 29 cases (31%). Follow-up is complete (median 4.4 years). RESULTS Early mortality was 5.6% (n = 3), with 2 late deaths. Kaplan-Meier survivals (+/- SEM) were 94.4% +/- 3.1% at 1 year and 89.7% +/- 4.4% at 9 years. Survivals at 7 years were 84.9% +/- 7.1% in the double-switch group and 95.5% +/- 4.4% in the Rastelli-Senning group (P =.32). Of the 49 survivors, 46 (94%) were in New York Heart Association functional class I. Six have acquired new left ventricular dilatation or impaired systolic ventricular function. Four patients in the double-switch group had moderate aortic valve regurgitation develop, and 2 of them required valve replacement. Overall freedoms from reoperation at 1 and 9 years were 94.2% +/- 3.3% and 77.5% +/- 9.0%, with no significant difference between the groups (P =.60). CONCLUSIONS Anatomic repair of congenitally corrected transposition of the great arteries can be carried out with low early mortality. Excellent functional status can be achieved, with good midterm survival. Continued surveillance is necessary for patents with valved conduits and to determine the longer-term function of the aortic valve and the morphologically left ventricle in the systemic circulation.

Abstract
OBJECTIVE Late results after traditional methods of repair of congenitally corrected transposition of the great arteries are poor. The combined arterial switch and Senning (double switch) operation may improve outcomes by using the morphologically left ventricle and mitral valve in the systemic circulation. In this report we review patient selection and intermediate results after the double switch operation for congenitally corrected transposition of the great arteries. METHODS Since 1993, a total of 35 patients with congenitally corrected transposition of the great arteries with two ventricles of adequate size and no valvular pulmonary stenosis were potential candidates for a double switch operation. Eleven were not yet in need of further treatment, and 1 died during evaluation. The remaining 23 patients were entered into a protocol leading to anatomic repair. Their hospital records were reviewed, and follow-up data were obtained to evaluate early and intermediate outcomes. RESULTS The 23 patients were candidates for anatomic repair because of right ventricular dysfunction or tricuspid regurgitation (n = 15) or associated uncorrected defects (n = 8). Pulmonary artery banding was performed in a total of 15 patients, either for left ventricular retraining (n = 11) or for congestive heart failure (n = 4). In 2 patients, aged 12 and 14 years, retraining was unsuccessful because of left ventricular dysfunction. Four patients with banding are currently awaiting repair. Eight patients proceeded to undergo double switch operations without preliminary pulmonary artery banding. To date, 17 patients have undergone double switch operations, with no early or late mortality. One patient required cardiac transplantation for progressive left ventricular failure after a preliminary banding and double switch operation done at 7 years of age. Ventricular function and tricuspid regurgitation remained stable or improved in all other cases. No patient has surgically acquired arrhythmias or significant residual hemodynamic conditions. All patients are alive and clinically well at a mean follow-up of 36 months (range 1 month-8 years). CONCLUSIONS Congenitally corrected transposition of the great arteries with a normal pulmonary valve and two adequate ventricles can be managed with combined arterial switch and Senning operation with excellent intermediate results. Reconditioning the left ventricle may not be suitable for older patients. Late follow-up will be necessary to determine whether this management strategy provides a survival advantage for these patients.

Abstract
A Senning plus Rastelli operation was performed in a patient who had a rare combination of congenitally corrected transposition of the great arteries (S,L,L) with dextrocardia, major aortopulmonary collaterals, and diminutive central pulmonary arteries with arborization defects. The patient required four preparatory operations including bilateral unifocalizations of the aortopulmonary artery collaterals. Pulmonary artery to systemic pressure ratio after the double switch operation was 0.6. The patient demonstrates good biventricular function on echocardiogram at 3 months after the operation.

Abstract
BACKGROUND The advent of double switch procedures for the treatment of transposition of the great arteries with L-looped ventricles, e.g. typical congenitally corrected transposition of the great arteries, has made delineation of the coronary artery anatomy in these hearts important. Previous studies have suggested a consistently inverted coronary arterial pattern. METHODS A morphologic study was conducted of the coronary arterial anatomy of all heart specimens in our registry of approximately 2600 hearts with segmental anatomy [S,L,L] (situs solitus of the viscera and atria, ventricular L-loop, and levoposition of the aorta), with anatomical features to permit such repair. RESULTS Twenty specimens collected between 1965 and 1993 ranged in age from 1 day to 23 years. Transposition of the great arteries or double outlet right ventricle was seen in 12 (60%). One had a single coronary artery that arose from the right anterior sinus and trifurcated. Another had the anterior descending artery arise from the right ventricular coronary artery while the circumflex arose alone, directly above the intercoronary commissure. Eccentric ostia were seen in another four, with one left ventricular coronary artery originating directly above the intercoronary commissure. Right ventricular aorta with pulmonary atresia was in eight of the total (40%). Three had eccentric ostia: one with both arteries from the left posterior sinus, and one with the left ventricular coronary over the intercoronary commissure. None of these specimens had additional coronary anomalies that would further complicate surgery. CONCLUSION Nearly half of the specimens (45%) had coronary artery abnormalities that could have complicated, but not necessarily precluded, anatomic surgical repair.

Abstract
BACKGROUND Failure of the systemic right ventricle (RV) often complicates adult survival in unoperated or physiologically repaired congenitally corrected transposition of the great arteries (CCTGA). Healthy controls schematically represent an optimal outcome of anatomic repair, which is increasingly performed to treat CCTGA. Magnetic resonance imaging dobutamine stress testing measures cardiac reserve, and sets to compare the left ventricle of controls with the systemic RV of unoperated and physiologically repaired patients with CCTGA. METHODS Baseline and stress magnetic resonance imaging (maximum dobutamine dose, 15 microg/kg/min) assessed systemic RV function in 13 minimally or asymptomatic adult patients with CCTGA (unoperated, n = 7; physiologically repaired, n = 6). The left ventricles of 11 healthy age-matched adults served as controls. RESULTS Baseline and stress end-diastolic volumes similar between the systemic RV of unoperated patients and the left ventricle of controls, as well as base end-systolic volumes. Stress ejection fraction was lower in unoperated and physiologically repaired patients (70 +/- 6% and 60 +/- 5%, respectively, vs healthy controls (84 +/- 8%). However, comparable with healthy controls, both subsets of CCTGA patients responded appropriately to dobutamine stress, as illustrated by similar RV stroke volume, heart rate, mean blood pressure, and cardiac index. CONCLUSIONS Compared with the left ventricles of healthy controls, both patient groups had larger systemic RV volumes, diminished ejection fraction, but an appropriate response to dobutamine stress. Values of unoperated patients are closer to normal than physiologically repaired patients. Magnetic resonance imaging dobutamine may help to define the subgroups of CCTGA patients with favorable anatomy, whereby asymptomatic adult survival could be anticipated without the need for an operation.

Abstract
BACKGROUND Anatomic repair of congenitally corrected transposition of the great arteries has several advantages over the traditional approach but lacks long-term evaluation. METHODS The data on 12 patients who had the procedure between January 1989 and June 2000 were retrospectively reviewed. Associated lesions included ventricular septal defect in 12 patients, pulmonary stenosis in 10 patients, and moderate to severe tricuspid valve regurgitation in 4 patients. Mean age at operation was 9+/-3.6 months. All patients had venous switch Mustard procedure. Tunneling of the morphologic left ventricle through the ventricular septal defect to the aorta with insertion of right ventricular to pulmonary artery conduit was performed in 10 patients, and arterial switch operation in 2. Concomitant tricuspid valvuloplasty was done in 2 patients and ventricular septal defect enlargement in 1. RESULTS There was one hospital death (9%) in the patient who needed ventricular septal defect enlargement. Complications included atrioventricular block requiring pacemaker insertion in 1 patient (9%) and superior vena caval obstruction in 1 patient (9%). Follow-up is available on all patients 0.5 to 10 years (mean, 7.6+/-3.1 years). All patients are asymptomatic. Exercise test results on the three oldest patients were normal. Bradytachyarrhythmias developed in 4 patients (36%). Right ventricular to pulmonary artery conduit replacement was needed in 5 patients 2.2 to 7.1 years (mean 5.2+/-3.6 years) postoperatively. Mild to moderate tricuspid valve regurgitation persisted in 2 patients. Systemic left ventricular fractional shortening was 36% to 47% (mean, 39%+/-4.6%), and ejection fraction was 49% to 70% (mean, 60.8%+/-7.9%). CONCLUSIONS The double switch operation can be performed safely with minimal intermediate and long-term complications.

Abstract
The morphologically right ventricle (mRV) fails after managing systemic workload for a variable period of time in some patients with transposition of the great arteries (TGA) who have undergone an atrial switch operation and in patients with congenitally corrected transposition of the great arteries (cc-TGA). Conventional therapy for progressive mRV failure, including tricuspid valve replacement and cardiac transplantation, has been disappointing. Anatomical correction, reincorporating the morphologically left ventricle (mLV) into systemic circulation, was performed in a total of 84 patients (39 TGA, 45 cc-TGA) in 2 institutions (Royal Children Hospital 1981-1993; Cleveland Clinic Foundation 1993-1999). The mVL was retrained to generate systemic pressure by means of pulmonary artery band in 43 patients. The overall mortality for patients entering this program is 15.4% (8 early and 5 late operative deaths). All of the operative deaths were patients with TGA and a prior atrial switch operation. Four patients (5%) have been transplanted or are on a transplantation waiting list. In patients with TGA and previous atrial switch operation, older age and abnormal coronary anatomy was associated with a higher operative mortality. None of the measured parameters of the mLV and mRV were predictors of failure of mLV reconditioning. Follow-up echocardiographic evaluations of the 46 survivors of anatomical correction showed normal mRV function in 41 (89%) and normal mLV function in 42 patients (91%). mLV retraining and anatomical correction produces good results in prepubescent patients. The response of older patients is less predictable and associated with a higher early and late mortality. Copyright 2000 by W.B. Saunders Company
