Abstract
Objective This study aimed to investigate the relationship between technical performance scores (TPS) and the early prognosis of tetralogy of Fallot repair (TOF). Methods A retrospective study was conducted on TOF repair patients at our center from Oct 2017 to Oct 2022. Patients were classified into Class 1 (no residua), Class 2 (minor residua), or Class 3 (major residua) based on TPS derived from predischarge echocardiograms and need for reintervention. Statistical methods were used to assess the association between TPS and early prognosis. Results A total of 75 TOF repair patients (40% female, 60% male) were analyzed and categorized into TPS1 (24%), TPS2 (53.3%), and TPS3 (22.6%) based on pre-discharge echocardiographic findings. The median follow-up time was 7.0 months. The multivariable Cox regression analysis indicated that TPS3 scores are associated with a 12.68-fold increase in risk compared to TPS1 and TPS2 scores [95% CI = 12.68 (0.9∼179.28), P = 0.06]. The Spearman rank correlation analysis revealed a weak positive correlation between TPS classification and low cardiac output syndrome (r = 0.26, P = 0.03). However, there were no significant differences in ICU stay or duration of mechanical ventilation among the groups. Conclusion TPS3 after intracardiac TOF repair is associated with higher risk of early re-intervention, highlighting the importance of close follow-up and monitoring in this patient population. Patients who develop low cardiac output syndrome in the early postoperative period may have residual defects that require prompt identification.

Abstract
Tetralogy of Fallot with pulmonary stenosis has a diverse clinical spectrum with the degree of right ventricular outflow tract obstruction (RVOTO) and size of the branch pulmonary arteries driving clinical management. Optimal surgical management involves consideration of patient clinical status and degree and location (subvalvar, valvar, and supravalvar) of RVOTO. Timing of repair requires multidisciplinary decision-making and complete surgical repair with relief of RVOTO by either transannular patch or valve sparing repair techniques. The central goals of contemporary surgical management of tetralogy of Fallot incorporate maximizing survival, minimizing reintervention, and preserving right ventricular function across the lifespan.

Abstract
OBJECTIVE Neonates with tetralogy of Fallot and pulmonary atresia (TOF/PA) but no major aorta-pulmonary collaterals are dependent on the arterial duct for pulmonary blood flow and require early intervention, either by primary (PR) or staged repair (SR) with initial palliation (IP) followed by complete repair (CR). The optimal approach has not been established. METHODS Neonates with TOF/PA who underwent PR or SR were retrospectively reviewed from the Congenital Cardiac Research Collaborative. Outcomes were compared between PR and SR (IP + CR) strategies. Propensity scoring was used to adjust for baseline differences. The primary outcome was mortality. Secondary outcomes included complications, length of stay, cardiopulmonary bypass and anesthesia times, reintervention (RI), and pulmonary artery (PA) growth. RESULTS Of 282 neonates, 106 underwent PR and 176 underwent SR (IP: 144 surgical, 32 transcatheter). Patients who underwent SR were more likely to have DiGeorge syndrome and greater rates of mechanical ventilation before the initial intervention. Mortality was not significantly different. Duration of mechanical ventilation, inotrope use, and complication rates were similar. Cumulative length of stay, cardiopulmonary bypass, and anesthesia times favored PR (P ≤ .001). Early RI was more common in patients who underwent SR (rate ratio, 1.42; P = .003) but was similar after CR (P = .837). Conduit size at the time of CR was larger with SR. Right PA growth was greater with PR. CONCLUSIONS In neonates with TOF/PA, SR is more common in greater-risk patients. Accounting for this, SR and PR strategies have similar mortality. Perioperative morbidities, RI, and right PA growth generally favor PR, whereas SR allows for larger initial conduit implantation.

Ann Thorac Surg 2023; 115:445-451. [PMID: 36155772 DOI: 10.1016/j.athoracsur.2022.09.022] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 07/23/2022] [Accepted: 09/12/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND The optimal strategy for pulmonary atresia with ventricular septal defect (PA-VSD) without major aortopulmonary collateral arteries is yet to be defined. It remains unclear how primary complete repair compares with staged repair. METHODS This study reviewed the records of 107 patients with PA-VSD who were managed with systemic-to-pulmonary shunts from February 1989 to November 2019. Tables presenting summary statistics of patient and surgical data and Kaplan-Meier curves showing repair, mortality, and reoperation were created. Logistic regression analysis was performed to identify risk factors for repair, morbidity, and mortality. RESULTS A total of 91 (85%) patients achieved complete repair at a median age of 1 year (interquartile range [IQR], 8-20 months). Survival was as follows: 97 (90%) patients at 6 months, 91 (85%) at 20 months, and 87 (81%) at 10 years. A shunt diameter of 3.5 mm or less (P = .006) and shunt after 2009 (P < .001) were associated with earlier progression to complete repair. A shunt diameter of 3.5 mm or less was an independent risk factor for interstage morbidity (hazard ratio, 4.5; IQR, 1.1-18.5; P = .039), but it was not associated with complete repair (P = .75) or mortality (P = .62). The median follow-up period was 10.5 years (IQR, 3.6-18.8 years) from birth. CONCLUSIONS The complete repair and long-term survival rates of staged PA-VSD repair are high. The use of smaller shunts has resulted in earlier complete repair and is associated with increased risk of morbidity but not mortality.

Abstract
Abstract
Background
Reinterventions after tetralogy of Fallot repair (TOF) remains a common clinical problem. The objective of this study was to evaluate types of reintervention after TOF repair and identify the risk factors for reinterventions.
Methods
This retrospective study was conducted from 2010 to 2022 and included 171 patients with complete TOF repair. Patients were grouped according to the occurrence of reintervention into two groups: patients who did not have reintervention (n = 138) and those who required reintervention (n = 33).
Results
Median follow-up was 36 (13–67) months. The first reintervention was required in 33 patients. Freedom from the first reintervention at 1, 3, 5, and 7 years was 91%, 85%, 81%, and 76%, respectively. Surgical reintervention was required in 12 patients and transcatheter intervention in 21 patients. Second reinterventions were required in 11 patients; 4 had surgery, and 7 had a transcatheter intervention. Third reinterventions were performed on two patients; one had surgery, and one had a transcatheter intervention. The most common interventions were performed at the level of pulmonary arteries (n = 17), followed by the pulmonary valve and the right ventricular outflow tract (n = 15). The risk of reintervention was associated with the low weight (HR: 0.65 (95% CI: 0.48–0.88); P = 0.005) and small LPA diameter (HR: 0.36 (95% CI: 0.21–0.60); P < 0.001) at the time of the primary intervention and the nonuse of the transannular patch (HR: 0.27 (95% CI: 0.08–0.85); P = 0.026).
Conclusions
The risk of reintervention is high after tetralogy of Fallot repair. In our experience, the smaller the left pulmonary artery and weight at the repair time increased the risk of reintervention. Using a transannular patch in our series was associated with a lower risk of reintervention.

Abstract
Valve-sparing repair (VSR) of tetralogy of Fallot (TOF) tends to result in higher residual right ventricular outflow tract (RVOT) gradients. We evaluated the progression and clinical implications of RVOT gradients following VSR of TOF. Demographic, clinical, and operative data were retrospectively collected from consecutive TOF patients who underwent VSR at our institution between 01/2010 and 06/2021. RVOT gradient, pulmonary valve annulus (PVA) diameter and Boston Z-scores were recorded from serial echocardiograms. Data are presented as median and interquartile range or number and percentage. A total of 156 children (boys 92, 59%) underwent VSR at 6.5 (4.9-8.4) months of age and 6.6 kg (5.6- 7.7) weight. There was 1 (0.6%) operative mortality. The remaining 155 patients were followed for 69.4 months (4-106.2). RVOT gradient was 2.4m/s (1.7-2.9) at discharge. It transiently increased, then declined and stabilized during follow-up. PVA Z-score was -1.7 (-3.1 to 0.5) at discharge and 'grew' to -0.8 (-1.7 to 0.4) at last follow-up. Freedom from RVOT re-intervention was 97%, 94% and 91% at 1, 5 and 10-year follow-up. Among 67 (43%) patients with PVA Z-score < -2, a similar RVOT gradient pattern was observed and freedom from RVOT re-intervention was 97%, 95% and 95% at 1, 5 and 8-year follow-up. Following VSR of TOF, RVOT gradients transiently increase and then fall as PVA growth catches up, resulting in durable intermediate outcomes. Patients with PVA Z-score < -2 demonstrated a similar pattern of hemodynamics in the RVOT and excellent freedom from reintervention.

Abstract
BACKGROUND The aim of this study was to evaluate the long-term outcome and freedom from pulmonary valve replacement (PVR) after initial repair of tetralogy of Fallot (TOF). PATIENTS AND METHODS The cohort of 306 patients treated between 1980 and 2017 was divided into anatomical subgroups according to the diagnosis of TOF-pulmonary stenosis, TOF-pulmonary atresia and TOF-double outlet right ventricle. Patients were treated with transannular patch (TAP), valve sparing repair (VSR), or conduits from the right ventricle to the pulmonary arteries (RVPA conduits). RESULTS There were 21 deaths (6.9%), 14 being hospital deaths (4.6%) after primary correction and four deaths (1.3%) occurred after PVR. One patient died after a non-cardiac operation (0.3%). There were two late deaths (0.7%). During the past 12 years no early mortality has been observed. Ninety-one patients (30.4%) received PVR after a median of 12.1 ± 7.0 years with an early mortality of 4.4% (n = 4) and no late mortality. A significant difference in freedom from reoperation after TAP, VSR, and RVPA-conduits could be identified. Multivariate analysis displayed transannular repair (p = 0.016), primary palliation (p <0.001), the presence of major aortopulmonary collateral arteries (MAPCA; p = 0.023), and pulmonary valve Z-scores < - 4.0 (p = 0.040) as significant risk factors for PVR. CONCLUSION TOF repair has a beneficial long-term prognosis with low morbidity and mortality. Pulmonary valve Z-scores < - 4.0, transannular repair, and presence of MAPCAs are associated with earlier PVR. Non-VSRs and TOF-pulmonary atresia lead to earlier reoperation but have no negative impact on survival.

Abstract
Background As no data were available on the comparison of outcomes between modified Blalock-Taussig shunts (MBTs) vs. duct-stenting (DS) in patients with pulmonary atresia (PA) and an increased ductal tortuosity and in patients with pulmonary atresia and intact septum (PA-IVS) with right ventricle-dependent coronary circulation (RVDCC), we aimed to perform a single-center retrospective evaluation. Methods Between 2010 and 2019, 127 patients with duct-dependent pulmonary circulation (DDPC) underwent either MBTs (without additional repairs) (n = 56) or DS (n = 71). The primary endpoint was defined as arriving at the next planned surgery (Glenn or biventricular repair) avoiding one of the following: (1) unplanned surgery or unplanned perforation of the pulmonary valve (PVP) with a stent, (2) procedure-related permanent complications, and (3) death. Two subgroups were considered: (1) patients who had a ductal curvature index (DCI) >0.45 (n = 32) and (2) patients with PA-IVS and RVDCC (n = 13). Ductal curvature index (DCI) was measured in all the patients to assess the tortuosity of the ducts. Patients with DCI >0.45 were considered as being in a high-risk group for the duct-stenting; a previous study showed that the patients with a DCI < 0.45 had a better outcome when compared with those with a DCI> 0.45. Results The primary outcome was achieved equally in the two groups (77.5% in DS, 75% in MBTs). Hospital deaths, need for ECMO, and the occurrence of major complications was more frequent in the group with MBTs with an Odds Ratio (OR) of 5, 0.8, and 4, respectively, and a 95% Confidence Interval (CI) 1.1–22.6, 0.7–0.9, and 1.6–10.3, respectively, and a P-value < 0.05. For the two subgroups, the primary outcome was achieved in 64% of patients with a DCI >0.45 who received MBTs compared to 20% in those with DS (OR 3.5, 95% CI 1.2–10, P 0.005). While 74.1% of the patients with PA-IVS and RVDCC after DS had achieved the primary outcome, all patients with MBTs had an impaired outcome (OR 3.5, 95%CI 1–11.2, P 0.004). Conclusion MBTs showed a better outcome in patients with tortuous ducts compared to DS. DS seems to be superior in patients with DDPC with DCI <0.45 and patients with PA-IVS with RVDCC.

OBJECTIVES Our goal was to report the long-term serial follow-up after transatrial–transpulmonary repair of tetralogy of Fallot (TOF) and to describe the influence of the timing of the repair on outcome. METHODS We included all patients with TOF who had undergone transatrial–transpulmonary repair between 1970 and 2012. Records were reviewed for patient demographics, operative details and events during the follow-up period (death, pulmonary valve replacement, cardiac reinterventions and hospitalization/intervention for arrhythmias). In patients with elective early primary repair of TOF after 1990, a subanalysis of the optimal timing of TOF repair was performed. RESULTS A total of 453 patients were included (63% male patients; 65% had transannular patch); 261 patients underwent primary elective repair after 1990. The median age at TOF repair was 0.7 years (25th–75th percentile 0.3–1.3) and decreased from 1.7 to 0.4 years from before 1990 to after 2000, respectively (P < 0.001). The median follow-up duration after TOF repair was 16.8 years (9.6–24.7). Events developed in 182 (40%) patients. In multivariable analysis, early repair of TOF (<6 months) [hazard ratio (HR) 3.06; P < 0.001] and complications after TOF repair (HR 2.18; P = 0.006) were found to be predictive for an event. In a subanalysis of the primary repair of TOF after 1990, the patients (n = 125) with elective early repair (<6 months) experienced significantly worse event-free survival compared to patients who had elective repair later (n = 136). In multivariable analysis, early repair (HR 3.00; P = 0.001) and postoperative complications (HR 2.12; P = 0.010) were associated with events in electively repaired patients with TOF. CONCLUSIONS Transatrial–transpulmonary repair of TOF before the age of 6 months may be associated with more events during the long-term follow-up period.

Abstract
BACKGROUND To evaluate whether a quantitative curvature threshold can contribute to risk stratification of ductal stenting in patients with a duct-dependent pulmonary circulation (DDPC). METHODS A single-center retrospective analysis was performed. The ductal curvature index (DCI) was calculated in 71 patients with DDPC. The ducts were divided into four classes based on quartile thresholds of DCI: class I (≤0.12), class II (0.13-0.33), class III (0.34-0.44), and class IV (≥0.45). The primary outcome of this study was defined as free from all of the following: (I) intervention related death, (II) need of unplanned surgery (III) need of unplanned pulmonary valve (PV) perforation with stent in right ventricular outflow tract (RVOT), and (IV) intervention related permanent complications. RESULTS Eighty percent of patients in class IV (DCI ≥0.45) failed to achieve the primary outcome; odds ratio (OR) 9 and 95% confidence interval (CI): 3.7-21.4 compared to 26.6% in all classes with DCI <0.45. 66.7% of these patients needed unplanned surgery or PVP with RVOT stent; OR 12.4 (95% CI: 4-39). 80% of major complications were observed in class IV (P<0.01). Need of pulmonary arterioplasty was in class IV 53.3%; OR 3.3 (95% CI: 1.5-7.1). CONCLUSIONS DCI can be useful to guide the clinical decision-making in patients with torqued ducts. Patients with a DCI ≥0.45 belong to a high-risk group, in which ductal stenting is associated with an elevated risk for early surgery or unplanned re-intervention.

Abstract
BACKGROUND This study evaluated the impact of a staged surgical strategy incorporating a modified Blalock-Taussig shunt (BTS) for tetralogy of Fallot (TOF) on pulmonary valve annulus (PVA) growth, the rate of valve-sparing repair (VSR) at the time of intracardiac repair (ICR), and long-term functional outcomes. METHODS This retrospective study included 330 patients with TOF who underwent ICR between 1991 and 2019, including 57 patients (17%) who underwent BTS. The mean follow-up period was 15.0±7.3 years. We compared the data of patients who underwent BTS and those who did not undergo BTS before ICR. RESULTS The median age and body weight before BTS were 71 (28-199) days and 4.3 (3.3-6.8) kg respectively. There were no in-hospital or interstage deaths after BTS. The PVA Z-scores of patients with BTS revealed significant growth after BTS (from -4.2±1.8 to -3.0±1.7, P<0.001). VSR was eventually performed in 207 (63%) patients, including 26 (46%) patients who underwent staged repair. The overall freedom from pulmonary regurgitation-related reintervention were 99.7%, 99.1%, and 95.8% at 1, 5, and 20 years, respectively. CONCLUSIONS A staged surgical strategy incorporating BTS as the first palliation for symptomatic patients resulted in no mortality. BTS may have contributed to the avoidance of primary transannular patch repair (TAP) and facilitated PVA growth; therefore, approximately half of the symptomatic neonates and infants were recruited for VSR. Staged repair may have led to functionally-reliable delayed TAP repair, thereby resulting in less surgical reinterventions.

Abstract
In the past decade, balloon-expandable percutaneous pulmonary valves have been developed and applied in clinical practice. However, all the existing products of pulmonary artery interventional valves in the market have a straight structure design, and they require a preset support frame and balloon expansion. This shape design of the valve limits the application range. In addition, the age of the population with pulmonary artery disease is generally low, and the existing products cannot meet the needs of anti-calcification properties and valve material durability. In this study, through optimization of the support frame and leaflet design, a self-expanding pulmonary valve product with a double bell-shaped frame was designed to improve the match of the valve and the implantation site. A loading and deployment study showed that the biomaterial of the valve was not damaged after being compressed. Pulsatile flow and fatigue in vitro tests showed that the fabricated pulmonary valve met the hydrodynamic requirements after 2 × 108 accelerated fatigue cycles. The safety and efficacy of the pulmonary valve product were demonstrated in studies of pulmonary valve implantation in 11 pigs. Angiography and echocardiography showed that the pulmonary valves were implanted in a good position, and they had normal closure and acceptable valvular regurgitation. The 180 days' implantation results showed that the calcium content was 0.31-1.39 mg/g in the anti-calcification treatment group, which was significantly lower than that in the control valve without anti-calcification treatment (16.69 mg/g). Our new interventional pulmonary valve product was ready for clinical trials and product registration.

Abstract
Background Despite excellent operative survival, correction of tetralogy of Fallot frequently is accompanied by residual lesions that may affect health beyond the incident hospitalization. Measuring resource utilization, specifically cost and length of stay, provides an integrated measure of morbidity not appreciable in traditional outcomes. Methods and Results We conducted a retrospective cohort study, using de‐identified commercial insurance claims data, of 269 children who underwent operative correction of tetralogy of Fallot from January 2004 to September 2015 with ≥2 years of continuous follow‐up (1) to describe resource utilization for the incident hospitalization and subsequent 2 years, (2) to determine whether prolonged length of stay (>7 days) in the incident hospitalization was associated with increased subsequent resource utilization, and (3) to explore whether there was regional variation in resource utilization with both direct comparisons and multivariable models adjusting for known covariates. Subjects with prolonged incident hospitalization length of stay demonstrated greater resource utilization (total cost as well as counts of outpatient visits, hospitalizations, and catheterizations) after hospital discharge (P<0.0001 for each), though the number of subsequent operative and transcatheter interventions were not significantly different. Regional differences were observed in the cost of incident hospitalization as well as subsequent hospitalizations, outpatient visits, and the costs associated with each. Conclusions This study is the first to report short‐ and medium‐term resource utilization following tetralogy of Fallot operative correction. It also demonstrates that prolonged length of stay in the initial hospitalization is associated with increased subsequent resource utilization. This should motivate research to determine whether these differences are because of modifiable factors.

Abstract
There is a lack of consensus regarding the preoperative pulmonary valve (PV) Z-score “cut-off” in tetralogy of Fallot (ToF) patients to attempt a successful valve sparing surgery (VSS). Therefore, the aim of this study was to review the available evidence regarding the association between preoperative PV Z-score and rate of re-intervention for residual right ventricular outflow tract (RVOT) obstruction, i.e. successful valve sparing surgery. A systematic search of studies reporting outcomes of VSS for ToF was performed utilizing PubMed, EMBASE, and Scopus databases. Patients with ToF variants such as pulmonary atresia, major aortopulmonary collaterals, absent pulmonary valve, associated atrioventricular septal defect, and discontinuous pulmonary arteries were excluded. Out of 712 screened publications, 15 studies met inclusion criteria. A total of 1091 patients had surgery at a median age and weight of 6.9 months and 7.2 kg, respectively. VSS was performed on the basis of intraoperative PV assessment in 14 out of 15 studies. The median preoperative PV Z-score was −1.7 (0 to −4.9) with a median re-intervention rate of 4.7% (0–36.8%) during a median follow-up of 2.83 years (1.4–15.8 years). Quantitatively, there was no correlation between decreasing preoperative PV Z-scores and increasing RVOT re-intervention rates with a correlation coefficient of −0.03 and an associated p-value of 0.91. In observational studies, VSS for ToF repair was based on intraoperative evaluation and sizing of the PV following complete relief of all levels of obstruction of the RVOT, rather than pre-operative echocardiography derived PV Z-scores.

Abstract
Recent advances in catheterization and imaging technology allow for more complex procedures to be performed in the catheterization laboratory. A number of lesions are now amenable to a percutaneous procedure, eliminating or at least postponing the need for a surgical intervention. Due to the increase in the complexity of the procedures performed, the involvement of anesthesiologists and their close collaboration with the interventional cardiologists have increased. It is important to understand the physiology and pathophysiology of the patients and to anticipate the plans and the potential complications in order to manage them. We are witnessing a rise in the number of complex interventions in newborns and infants, such as balloon valvotomy (critical aortic stenosis, pulmonary stenosis), radio frequency perforation (of pulmonary atresia and intact ventricular septum), right ventricular outflow tract stenting (in Tetralogy of Fallot), ductal stenting (in some ductus-dependent pulmonary circulation), and combined with a surgical procedure (hybrid procedure for hypoplastic left heart syndrome). Multiple registries have been created in order to understand and improve outcomes of patients with congenital heart disease undergoing catheterization procedures and to develop performance and quality metrics, from which data regarding anesthetic-related risks can be extrapolated. Experienced personnel and a multidisciplinary team approach with direct communication among the team members is a must to ensure anticipation and management of critical events when they occur.
