Reoperations in Adolescents and Adults After Prior Arterial Switch Operation: The Society of Thoracic Surgeons Congenital Heart Surgery Database Analysis. Ann Thorac Surg 2024:S0003-4975(24)00468-5. [PMID: 38878952 DOI: 10.1016/j.athoracsur.2024.05.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/18/2024] [Accepted: 05/13/2024] [Indexed: 07/14/2024]
Abstract
BACKGROUND Arterial switch operation (ASO) has supplanted physiologic repairs for transposition of the great arteries and related anomalies. As survival rates have increased, so has the potential need for cardiac reoperations to address ASO-related complications arising later in life. METHODS The Society of Thoracic Surgeons Congenital Heart Surgery Database (2010-2021) was reviewed to assess prevalence and types of cardiac reoperations for patients aged ≥10 years with prior ASO for transposition of the great arteries or double-outlet right ventricle/transposition of the great arteries type. A hierarchical stratification designating 13 procedure categories was established a priori by investigators. Each eligible surgical hospitalization was assigned to the single highest applicable hierarchical category. Outcomes were compared across procedure categories, excluding hospitalizations limited to pacemaker-only and mechanical circulatory support-only procedures. Variation during the study period in relative proportions of left heart vs non-left heart procedure category encounters was assessed. RESULTS There were 698 cardiac surgical hospitalizations for patients aged 10 to 35 years at 100 centers. The most common left heart procedure categories were aortic valve procedures (n = 146), aortic root procedures (n = 117), and coronary artery procedures (n = 40). Of 619 hospitalizations eligible for outcomes analysis, major complications occurred in 11% (67/619). Discharge mortality was 2.3% (14/619). Year-by-year analysis of surgical hospitalizations reveals substantial growth in numbers for the aggregate of all procedure categories. Growth in relative proportions of left heart vs non-left heart procedures was significant (P = .0029; Cochran-Armitage trend test). CONCLUSIONS This large multicenter study of post-ASO reoperations beyond early childhood documents year-over-year growth in total reoperations. Left-sided heart procedures recently had the highest rate of rise. These observations have implications for counseling, surveillance, and management.

Ann Thorac Surg 2018; 106:1827-1833. [PMID: 30172857 DOI: 10.1016/j.athoracsur.2018.06.084] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Revised: 06/25/2018] [Accepted: 06/27/2018] [Indexed: 11/18/2022]
Abstract
BACKGROUND The arterial switch operation (ASO) became the procedure of choice for dextro-transposition of the great arteries (d-TGA) nearly 30 years ago, but the long-term results of this operation are unknown. We aimed to compare the long-term transplant-free survival of patients with d-TGA who underwent ASO versus atrial switch in the Pediatric Cardiac Care Consortium. METHODS We performed a retrospective cohort study of d-TGA patients undergoing ASO or atrial switch in the United States between 1982 and 1991. Long-term transplant-free survival was obtained by linking Pediatric Cardiac Care Consortium data with the National Death Index and the Organ Procurement and Transplant Network. Kaplan-Meier survival plots were constructed, and multivariable regression was used to compare long-term transplant-free survival. RESULTS Of 554 d-TGA patients who underwent ASO (n = 259) or atrial switch (n = 295), the 20-year overall transplant-free survival was 82.1% for those undergoing ASO and 76.3% for those who had atrial switch procedure. Adjusted overall transplant-free survival beyond 10 years after operation was superior for ASO compared with atrial switch (hazard ratio 0.07, 95% confidence interval: 0.01 to 0.52, p = 0.009). During this period, the ASO had higher in-hospital mortality than the atrial switch (21.6% versus 12.9%, p = 0.007). After excluding patients with in-hospital mortality, the transplant-free survival 20 years after repair was 97.7% for the ASO patients versus 86.3% for the atrial switch patients. CONCLUSIONS Despite initial higher in-hospital mortality for ASO during the study period, there is a significant long-term transplant-free survival advantage for ASO as compared with atrial switch for d-TGA surgery. Ongoing monitoring is required to assess late risk of cardiovascular disease.

Abstract
BACKGROUND Tricuspid valve insufficiency secondary to structural anomalies of the valve itself or to an iatrogenic complication of the Rashkind procedure is very rarely associated with transposition of the the great arteries. This condition represents an interesting perioperative challenge. Rapid restoration of the tricuspid valve to a low-pressure system by arterial switch operation associated with tricuspid repair should theoretically improve the outcome in terms of myocardial and valve function. METHODS Thirteen of 839 patients who underwent an arterial switch operation for various forms of transposition of the great arteries presented with moderate to severe tricuspid insufficiency. Three of them had a ventricular septum defect. Nine experienced severe cardiac failure with profound hypoxemia. Ventilatory support was necessary in 7, 6 had renal or hepatic dysfunction, and 5 had coagulation disorders. Inotropic support was started preoperatively in 8 patients. RESULTS Tricuspid lesions were as follows: primary annular dilatation and lack of coaptation at the commissural level (n = 1), straddling tricuspid valve (n = 1) redundant tricuspid valve tissue leading to left ventricular outflow tract obstruction (n = 1), small cleft of the septal leaflet (n = 1), and dysplastic valve tissue with juxtacommissural regurgitation (n = 1). In 8 patients, the cause of the tricuspid valve insufficiency was most probably an iatrogenic lesion, with rupture of the papillary muscle (n = 2), rupture of the chordae (n = 1), or tear of the anterior leaflet (n = 5), whereas no clear cause could be found in 1 patient. Repair consisted of the arterial switch operation associated with tricuspid valve repair in 10 patients. In 2 patients with only discrete anomaly and in 1 without a clear cause of tricuspid regurgitation, no valve repair was performed. Three patients had their ventricular septal defect closed. There were only one early and one late death, both not related to the tricuspid lesions. Late postoperative (mean, 6.5 years) evaluation revealed normal left ventricular function in 10, with no tricuspid incompetence in 7 and trivial tricuspid insufficiency in 3. CONCLUSIONS Restoration of an incompetent tricuspid valve in a low-pressure system by the arterial switch operation combined with valve repair provides good ventricular and valvar results. Preoperative management and appropriate timing of operation seem to be of utmost importance.

Abstract
Seventy three infants who underwent neonatal anatomical correction for transposition of the great arteries with or without a ventricular septal defect were reviewed for evidence of conduction and rhythm abnormalities on preoperative and postoperative 12 lead electrocardiograms and during 24 hour Holter monitoring. There was a partial right bundle branch block pattern in 47% (29/62) of all patients and in 60% (24/40) of those with simple transposition. Complete right bundle branch block was noted in 21% including 5% with simple transposition. Holter monitoring showed sinus rhythm in all patients except three: one had episodes of supraventricular tachycardia, another an intermittent second degree heart block, and a third a complete heart block. Atrial extrasystoles were noted in 47% (29/62) of patients but were frequent in only three patients. Occasional unifocal ventricular extrasystoles were encountered in 37% (23/62) of patients and were frequent in a further 3% (2/62). Only one patient (2%) developed multifocal ventricular extrasystoles. The frequency of important cardiac arrhythmias after neonatal anatomical correction of transposition of the great arteries was 5%, significantly less than that reported after atrial inflow diversion for the same malformation.

Abstract
Thirteen patients, 12 of whom younger than 2 years, underwent a Damus-Kaye-Stansel procedure for complete transposition of the great arteries, ventricular septal defect, or double-outlet right ventricle and subpulmonary ventricular septal defect. In 6 patients, associated cardiac anomalies caused systemic flow obstruction. There were six hospital deaths (mortality rate, 42%). In a mean follow-up period of 57 months, 5 of 7 survivors required relief of right ventricular hypertension through conduit replacement or enlargement (4 patients) or conduit valve balloon dilation (1 patient). The aortic valve became regurgitant in 2 patients in whom it had been left in potential connection with the right ventricle. One patient has moderate pulmonary valve regurgitation. The main advantage of the Damus-Kaye-Stansel procedure is that it avoids coronary relocation; also, the spatial relationship of the great arteries and the coronary anatomy do not affect its feasibility. One drawback is the need for a conduit in infancy. Our present indication for Damus-Kaye-Stansel procedure is confined to double-outlet right ventricle with subpulmonary ventricular septal defect; 5 of 6 patients survived repair in this series. Possible indications are for patients with associated subaortic obstruction or unusual coronary arrangements. Fresh or cryopreserved homografts as extracardiac conduits and primary closure of the subaortic area may reduce the need for reoperation after Damus-Kaye-Stansel procedure.

Abstract
Twenty children who were well six to 12 years after undergoing Mustard's operation for transposition of the great arteries were studied. Each child performed a graded maximal treadmill test with measurements of gas exchange and oxygen saturation, and had electrocardiography carried out. Nineteen were also catheterised, and oxygen consumption was measured so that pulmonary and systemic flow could be calculated. Compared with 20 age and size matched controls, seven of the patients had normal exercise tolerance (as judged by a maximal oxygen consumption of greater than 40 ml/kg/min), 10 showed a moderate reduction (30-39 ml/kg/min), and three were more seriously limited. None of the patients with normal exercise tolerance had obstruction of venous return but six of those with mild impairment of exercise ability had partial or complete obstruction of one or both of the vena cavas. More severe limitation was associated with pulmonary vascular disease and fixed ventricular outflow tract obstruction. Formal exercise testing of apparently well children who have undergone Mustard's operation identifies those with haemodynamic abnormalities that may require intervention.

Abstract
Between January 1983 and December 1987, 62 patients underwent an arterial switch operation for transposition of the great arteries with ventricular septal defect or double outlet right or left ventricle. There were three hospital deaths (4.8%), and no deaths occurred in neonates (less than 1 month of age, n = 18). There were three late deaths, one due to coronary obstruction and two due to pulmonary vascular obstructive disease. One child has been lost to follow-up. We have prospectively evaluated the remaining 55 survivors by clinical evaluation, echocardiography, cardiac catheterization, ambulatory electrocardiographic monitoring, and limited electrophysiologic studies. The mean length of follow-up has been 27 +/- 16 months since surgery. One child has required reoperation for a residual ventricular septal defect; no child has undergone reoperation for supravalvar pulmonary or aortic stenosis. Aortic regurgitation was identified in 12 children (22%), which was mild in 11 and moderate in one. One child has asymptomatic occlusion of the left main coronary artery, one child has a tiny right coronary artery-to-pulmonary artery fistula, and one child has abnormal left ventricular wall motion according to follow-up angiography. No other abnormalities of systemic (left) ventricular function have been identified at late follow-up. In addition to the two late deaths due to pulmonary vascular obstructive disease, three children, all of whom were repaired at more than 6 months of age, have elevated pulmonary vascular resistance. Notable postoperative arrhythmias include complete heart block in four patients and nonsustained supraventricular or ventricular tachycardia early after surgery in eight patients (all resolved without medication at later follow-up). Only two patients have evidence of sinus node dysfunction and have not required treatment. The low hospital mortality and encouraging early follow-up data represent a significant improvement over atrial level repairs, supporting the arterial switch operation as the procedure of choice for children who have transposition of the great arteries with ventricular septal defect or double outlet ventricle. Because of the potential for the development of early pulmonary vascular obstructive disease in these patients, repair is recommended within the first 2 months of life.

Abstract
Overall survival after Mustard's operation was assessed in 130 patients with complete transposition of the great arteries and an intact ventricular septum who were operated on at the Brompton Hospital in the 12 year period from January 1974 to December 1985. Actuarial analysis showed a survival at five years of 79.1% (25 deaths in 130 patients). Half the deaths occurred within a month of operation and half up to five years later. Operation under the age of three months carried a greater mortality (six deaths in 11 patients). Statistical analysis showed that these survival figures were consistent throughout the series and did not alter with the year of operation. In the light of recent trends in treatment of this lesion, it is concluded that for neonates an arterial switch procedure is now likely to carry the best chance of long term success. For the patient who presents after the age of three months, however, there may still be a place for the Mustard procedure.

Abstract
The outlook for children with transposition of the great arteries (TGA) improved dramatically with the advent of the atrial repair. This procedure, first successfully performed by Ake Senning, followed years of unsuccessful attempts at correction by a number of surgeons using a variety of techniques. Senning's procedure expanded on the concept experimentally proposed by Albert of redirecting venous return at the atrial level to achieve physiological correction. The Senning procedure was largely abandoned when Mustard's technique was introduced in 1964, but has enjoyed a resurgence as a number of its potential advantages became more fully appreciated. Today, patients with TGA are increasingly undergoing repair by the arterial switch technique. Not all patients, however, are suitable candidates for this approach, and its success will be measured against the ingenious procedure described by Senning more than a quarter of a century ago.

Abstract
Anatomical repair of transposition of the great arteries (TGA) seems more attractive than the more conventional atrial baffle procedures because of resultant left ventricular-aortic continuity. The results of anatomical repair in 16 consecutive neonates with TGA and intact ventricular septum were reviewed; special consideration was given to technique and guidelines to avoid complications. Infants underwent repair within 6 days of life (average weight, 3.3 kg). Survival was 88% (14 of 16 patients). One death occurred from pulmonary hypertension and atrial shunt reversal causing cyanosis after an uncomplicated procedure; the other was due to myocardial ischemia caused by kinking of an anomalous coronary artery after attempted repair. Complications of ventricular swelling and coronary tension or kinking were successfully treated by Silastic skin patches in 2 patients and pericardial aortic patches in 2, respectively. One patient had successful repair of supravalvular pulmonary stenosis. Because anatomical repair of TGA must be performed in the first week of life, special consideration must be given to meticulous anatomical dissection, careful coronary transfer, and optimal myocardial preservation. The excellent short-term results favor the continued application of anatomical repair of TGA with intact ventricular septum in infancy.

Abstract
Because of interest in the arterial switch operation, recent experience with the Senning operation in patients with simple and complex transposition of the great arteries (TGA) was examined. Between 1982 and 1985, 35 patients with simple TGA (group I) and 10 patients with complex TGA (group II) underwent a Senning operation. Mean duration of follow-up was 14 months for group I and 24 months for group II. In group I, 1 patient died early and no patient died late; infrequently, right ventricular dysfunction, tricuspid regurgitation, baffle obstruction or arrhythmias occurred. In group II, no patient died early and 3 died late. In addition, many patients required prolonged digoxin therapy. Because the arterial switch operation has a high early mortality risk and an undetermined long-term morbidity and mortality risk, the Senning operation (or other venous switch operations) is considered the preferred surgical approach for simple TGA. In contrast, an arterial switch operation is performed in patients with complex TGA (without subpulmonic obstruction). Comparison of the early and late morbidity and mortality of the arterial vs the venous switch operation may be helpful in selecting the appropriate surgical approach to complex TGA.
