Abstract
BACKGROUND Neo-aortic root dilatation and valve regurgitation are emerging problems late after arterial switch operation (ASO). We sought to evaluate the prevalence and outcomes of neo-aortic root or valve reoperation after ASO. METHODS All patients with biventricular circulation who underwent an ASO between 1983 and 2015 were included at a single institution. RESULTS In our cohort of 782 late ASO survivors, the median duration of follow-up was 18.1 years (interquartile range [IQR], 11.3-25.6 years). During follow-up, 47 patients (6.0%) underwent 60 reoperations on the neo-aortic valve/root. The first neo-aortic valve/root reoperation occurred at a median of 15.2 years (IQR, 7.8-18.4 years) after ASO. Operations included mechanical Bentall (31.9%; n = 15), aortic valve repair (25.5%; n = 12), mechanical aortic valve replacement (AVR) (21.3%; n = 10), valve-sparing root replacement (19.1%; n = 9), and the Ross procedure (2.1%; n = 1). There was 1 late death (2.1%). Multivariable predictors of neo-aortic valve/root reoperation were bicuspid valve (hazard ratio [HR], 4.8; 95% confidence interval [CI], 2.1-10.7; P < .001), Taussig-Bing anomaly (HR, 3.0; 95% CI, 1.2-7.4; P < .02), previous pulmonary artery band (HR, 2.8; 95% CI, 1.2-6.3; P < .01) and left ventricular outflow tract obstruction before ASO (HR, 2.4; 95% CI, 1.0-5.8; P < .04). Freedom from neo-aortic valve or root reoperation was 98.0% (95% CI, 96.7%-98.8%) at 10 years, 93.3% (95% CI, 90.8%-95.2%) at 20 years, and 88.5% (95% CI, 84.1%-91.8%) at 30 years after ASO. Among the 47 patients who underwent neo-aortic reoperation, freedom from AVR was 82.3% (95% CI, 67.7%-90.7%) at 10 years, 58.0% (95% CI, 41.8%-71.2%) at 20 years, and 43.2% (95% CI, 27.0%-58.3%) at 25 years after ASO. CONCLUSIONS The need for neo-aortic valve or root reoperation surpasses 10% by 30 years post-ASO. Evolving understanding of the mechanisms of neo-aortic valve insufficiency and techniques of neo-aortic valve repair may decrease the need for AVR.

Neoaortic Regurgitation Detected by Echocardiography After Arterial Switch Operation: A Systematic Review and Meta-Analysis. JACC. ADVANCES 2024; 3:100878. [PMID: 38939665 PMCID: PMC11198711 DOI: 10.1016/j.jacadv.2024.100878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 12/18/2023] [Accepted: 01/04/2024] [Indexed: 06/29/2024]
Abstract
Background Neoaortic root dilatation (NeoARD) and neoaortic regurgitation (NeoAR) are common sequelae following the arterial switch operation (ASO) for transposition of the great arteries. Objectives The authors aimed to estimate the cumulative incidence of NeoAR, assess whether larger neoaortic root dimensions were associated with NeoAR, and evaluate factors associated with the development of NeoAR during long-term follow-up. Methods Electronic databases were systematically searched for articles that assessed NeoAR and NeoARD after ASO, published before November 2022. The primary outcome was NeoAR, classified based on severity categories (trace, mild, moderate, and severe). Cumulative incidence was estimated from Kaplan-Meier curves, neoaortic root dimensions using Z-scores, and risk factors were evaluated using random-effects meta-analysis. Results Thirty publications, comprising a total of 6,169 patients, were included in this review. Pooled estimated cumulative incidence of ≥mild NeoAR and ≥moderate NeoAR at 30-year follow-up were 67.5% and 21.4%, respectively. At last follow-up, neoaortic Z-scores were larger at the annulus (mean difference [MD]: 1.17, 95% CI: 0.52-1.82, P < 0.001; MD: 1.38, 95% CI: 0.46-2.30, P = 0.003) and root (MD: 1.83, 95% CI: 1.16-2.49, P < 0.001; MD: 1.84, 95% CI: 1.07-2.60, P < 0.001) in patients with ≥mild and ≥moderate NeoAR, respectively, compared to those without NeoAR. Risk factors for the development of any NeoAR included prior pulmonary artery banding, presence of a ventricular septal defect, aorto-pulmonary mismatch, a bicuspid pulmonary valve, and NeoAR at discharge. Conclusions The risks of NeoARD and NeoAR increase over time following ASO surgery. Identified risk factors for NeoAR may alert the clinician that closer follow-up is needed.

Agematsu K, Nagashima M, Nishimura Y. Persistent neo-aortic root dilatation and aortic valve insufficiency after arterial switch operation following prior pulmonary artery banding. Indian J Thorac Cardiovasc Surg 2024; 40:107-110. [PMID: 38125325 PMCID: PMC10728024 DOI: 10.1007/s12055-023-01629-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 10/16/2023] [Accepted: 10/16/2023] [Indexed: 12/23/2023] Open
Abstract
Although there have been great improvements in the short- and medium-term outcomes of the arterial switch operation (ASO) for transposition of the great arteries (TGA), some complications including pulmonary artery stenosis, aortic valve insufficiency, and aortic root dilatation have also been reported. After ASO, the original pulmonary root and valve, which function in the systemic position as the neo-aortic root and valve respectively, are exposed to the systemic blood pressure, resulting in aortic root dilatation and valve insufficiency in some patients. One of the risk factors for these complications is a history of prior pulmonary artery banding (PAB). Complex TGA anatomy, including transposition of the great arteries and ventricular septal defect (TGA-VSD) or double outlet right ventricle and ventricular septal defect (DORV-VSD), is also an independent risk factor for neo-aortic dilatation and aortic valve regurgitation. Aortic valve and root replacement is sometime necessary for the patients with these pathologies long-term after ASO. Here, we present a patient who had persistent aortic sinus dilatation and aortic valve insufficiency since ASO and necessitating aortic root and valve replacement 15 years after ASO preceded by PAB. The patient underwent Bentall operation and his clinical course was favorable. Histological findings after root replacement revealed no remarkable structural difference between neo-aortic wall (originally pulmonary artery) and original aortic wall.

Abstract
PURPOSE Transposition of great arteries with intact ventricular septum and left ventricular outflow tract obstruction (TGA + IVS + LVOTO) is uncommon. We reviewed operations performed in patients with TGA + IVS + LVOTO in the European Congenital Heart Surgeons Association Congenital Database (ECHSA-CD). METHODS All 109 patients with a diagnosis of TGA + IVS + LVOTO in ECHSA-CD who underwent cardiac surgery during a 21-year period (01/2000-02/2021, inclusive) were included. Preoperative variables, operative data, and postoperative outcomes were collected. RESULTS These 109 patients underwent 176 operations, including 37 (21.0%) arterial switch operations (ASO), 26 (14.2%) modified Blalock-Taussig-Thomas shunts (MBTTS), 11 (6.2%) Rastelli operations, and 13 (7.3%) other palliative operations (8 superior cavopulmonary anastomosis[es], 4 Fontan, and 1 other palliative procedure). Of 37 patients undergoing ASO, 22 had a concomitant procedure.There were 68 (38.6%) reoperations, including 11 pacemaker procedures and 8 conduit operations. After a systemic-to-pulmonary artery shunt, reoperations included shunt reoperation (n = 4), Rastelli (n = 4), and superior cavopulmonary anastomosis (n = 3).Overall Operative Mortality was 8.2% (9 deaths), including three following ASO, two following "Nikaidoh, Kawashima, or LV-PA conduit" procedures, and two following Rastelli. Postoperative complications occurred after 36 operations (20.4%). The most common complications were delayed sternal closure (n = 11), postoperative respiratory insufficiency requiring mechanical ventilation >7 days (n = 9), and renal failure requiring temporary dialysis (n = 8). CONCLUSION TGA + IVS + LVOTO is rare (109 patients in ECHSA-CD over 21 years). ASO, MBTTS, and Rastelli are the most common operations performed for TGA + IVS + LVOTO. Larger international studies with long-term follow-up are needed to better define the anatomy of the LVOTO and to determine the optimal surgical strategy.

Abstract
To identify risk factors associated with mortality and reintervention on primary arterial switch operation for Taussig-Bing anomaly in 225 cases over a 16-year period. From 2002 to 2017, 225 children with Taussig-Bing anomaly received a primary arterial switch operation at the Shanghai Children's Medical Center. Perioperative data and follow-up results were collected. Univariate and multivariable analysis was used to explore risk factors associated with early mortality. The competing risk analysis was used to identify risk factors related to reintervention. Early mortality was 12.9% (29/225) with a satisfactory long-term survival rate (10-year survival rate 85.0%). The median age at repair was 77 days (interquartile range, IQR, 48-139). The median duration of follow-up was 4.6 (range 0.1-18.3) years. 87 children (38.7%) received concomitant aortic arch repair. Prolonged cardiopulmonary bypass time (a-OR 1.18, 95% confidence interval [CI], 1.09-1.28, p < 0.001) is found to be an independent risk factor for early death. Larger weight at repair tends to be a protective factor (a-OR 0.66, 95% CI, 0.425-1.02, p = 0.060) and intramural coronary artery (a-OR 4.81, 95% CI, 0.927-24.9, p = 0.062) tends to be a risk factor for early mortality. The cumulative incidence rate of overall reintervention was 18.9% (95% CI, 10.3%-27.4%) at 5 years and 32.3% (95% CI, 17,0%-47.6%) at 10 years. No independent risk factors were identified for long-term overall reintervention. Prolonged aortic-cross clamp time was an independent risk factor for long-term right-sided reintervention (adjusted hazard ratio [a-HR] 1.12, 95% CI 1.005-1.25, p = 0.041). Neo-aortic regurgitation was a concern with an incidence rate of moderate or greater neo-AR of 16.1 % (95% CI 7.6%-24.7%) at 10 years. Intramural coronary artery remains a surgical challenge in primary arterial switch operation for the Taussig-Bing anomaly. Larger weight at ASO tends to be a protective factor for early death. Reintervention is frequently necessary but can be performed with satisfactory results.

Abstract
Objective The objective of this study was to evaluate the long-term surgical results of transposition of the great arteries with left ventricular outflow tract obstruction. Methods We conducted a retrospective study of patients with transposition of the great arteries or double outlet right ventricle with left ventricular outflow tract obstruction undergoing biventricular repair between 1980 and 2017. Results One hundred and eleven patients were enrolled and classified into five groups: atrial switch (n = 20), arterial switch (n = 12), Nikaidoh (n = 7), Rastelli (n = 48), and REV operation groups (n = 24). Early mortality was highest in Nikaidoh group (29%). Median follow-up was 18.2 years. Long-term survival was by far lowest in Nikaidoh group and comparable among the other 4 groups. Freedom from reoperation at 20 years was lowest in Rastelli group (32.1%) due to right ventricular outflow tract-related reoperations. While having no recurrence of left ventricular outflow tract obstruction, the arterial switch operation group had a high proportion of substantial neo-aortic regurgitation (29%). Conclusions The long-term survival was satisfactory regardless of the surgical technique except Nikaidoh group. The surgical option for transposition of the great arteries with left ventricular outflow tract obstruction should be selected based on the features of the respective procedures.

Abstract
Background Neo-aortic root dilation and neo-aortic regurgitation (AR) are common after arterial switch operation for D-loop transposition of the great arteries. We sought to evaluate these outcomes in patients with bicuspid native pulmonary valve (BNPV). Methods and Results A retrospective analysis of patients with transposition of the great arteries undergoing arterial switch operation at Boston Children's Hospital from 1989 to 2018 matched BNPV patients 1:3 with patients with tricuspid native pulmonary valve by year of arterial switch operation. Kaplan-Meier analyses with log-rank test compared groups for time to first neo-aortic valve reoperation, occurrence of ≥moderate AR, and neo-aortic root dilation (root z score ≥4). A total of 83 patients with BNPV were matched with 217 patients with tricuspid native pulmonary valve. Patients with BNPV more often had ventricular septal defects (73% versus 43%; P<0.001). Hospital length of stay (11 versus 10 days) and 30-day surgical mortality (3.6% versus 2.8%) were similar. During median 11 years follow-up, neo-aortic valve reoperation occurred in 4 patients with BNPV (6.0%) versus 6 patients with tricuspid native pulmonary valve (2.8%), with no significant difference in time to reoperation. More BNPV had AR at discharge (4.9% versus 0%; P=0.014) and during follow-up (13.4% versus 4.3%; hazard ratio [HR], 3.9; P=0.004), with shorter time to first occurrence of AR; this remained significant after adjusting for ventricular septal defects. Similarly, neo-aortic root dilation was more common in BNPV (45% versus 38%; HR, 1.64; P=0.026) with shorter time to first occurrence. Conclusions While patients with BNPV have similar short-term arterial switch operation outcomes, AR and neo-aortic root dilation occur more frequently and earlier compared with patients with tricuspid native pulmonary valve. Further long-term studies are needed to determine whether this results in greater need for neo-aortic valve reoperation.

Abstract
OBJECTIVE The timing and nature of and risk factors for reoperation after the arterial switch operation in the setting of d-transposition of the great arteries requires further elucidation. METHODS A total of 403 patients who underwent arterial switch operation from 1986 to 2017 were reviewed. Institutional preference was for pulmonary artery reconstruction using a pantaloon patch of fresh autologous pericardium. The targets for coronary artery reimplantation were identified by intermittent root distension. Multivariable analysis was used to identify risk factors for reoperation. RESULTS Median follow-up was 8.6 years (interquartile range [IQR]: 2-16.9). Pulmonary arterioplasty was the most common reoperation (n = 11, 2.7%) at 3.3 years (IQR: 1.4-11.4) postoperatively. Subvalvar right ventricular outflow tract reconstruction (RVOTR) was required in nine (2.2%) patients at 2.5 years (IQR: 1.1-5.3) postoperatively. Aortic valve repair or replacement (AVR/r) was required in seven (1.7%) patients at 13.6 years (IQR: 10.0-15.8) postoperatively. Aortic root replacement (ARR) and Coronary Artery Bypass Graft/coronary patch arterioplasty were required in five (1.2%) patients each at 13.6 years (IQR: 11.0-15.3) and 11.3 years (IQR: 2.3-13.6) postoperatively, respectively. Taussig-Bing anomaly was a risk factor for any reoperation (P = .034). Risk factors for specific reoperations included ventricular septal defect for AVR/r (P = .038), Taussig-Bing anomaly for RVOTR (P = .004), and pulmonary artery banding for ARR (P = .028). CONCLUSIONS Pantaloon patch pulmonary artery reconstruction and intermittent neo-aortic root distension during coronary reimplantation have minimized respective outflow tract reoperations. Certain anatomic subsets carry different risks for late reoperation, and pulmonary artery and/or RVOT reinterventions tend to occur sooner than aortic reinterventions. Special attention to these higher risk subpopulations will be critical to optimizing lifelong outcomes.

Predictors of neo-aortic valve regurgitation in the long term after arterial switch operation. Heart Vessels 2020; 36:693-703. [PMID: 33245489 DOI: 10.1007/s00380-020-01729-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 11/06/2020] [Indexed: 10/22/2022]
Abstract
Although arterial switch operations (ASOs) have been performed globally to repair d-transposition of the great arteries (d-TGA) in neonates and infants, few studies have been reported regarding the influence of the hemodynamics of patients with d-TGA who have undergone ASO on the development of neo-aortic valve regurgitation (AR). We aimed to investigate the relationship between the hemodynamics and development of AR after ASO in patients with d-TGA by catheter evaluation. This observational study screened 114 consecutive patients who underwent ASO for d-TGA or Taussig-Bing anomaly and who subsequently underwent catheter evaluations in our institution. We reviewed their records for the past 20 years and collected their first catheterization data post-ASO in early childhood. Thirty-six post-ASO patients who underwent catheter evaluations in both the early surgical and long-term phases were finally analyzed. Patients were divided into the following groups according to the presence of significant AR in the long-term phase: the AR group (n = 9 with AR ≥ grade II by the Sellers classification) and the non-AR group (n = 27 with AR < grade II). In the long-term phase, the diastolic blood pressure was significantly lower and the ascending aortic diameter was significantly larger in the AR group than in the non-AR group (p = 0.004 and p = 0.006, respectively). The systolic blood pressure (SBP) and pulse pressure (PP) were similar in both groups. Meanwhile, in the early surgical phase, SBP and PP were significantly higher in the AR group than in the non-AR group (p = 0.029 and p = 0.002, respectively). The receiver operating characteristic curve for late AR showed that the area under the curve for SBP and PP in the early surgical phase were 0.746 and 0.853, respectively. Even though sensitivity analysis was performed, SBP or PP greater than the cutoff value in the early surgical phase was identified as predictors for late AR. Our results suggested that high SBP or PP in the early surgical phase could influence the development of AR in the long term after ASO.
