Comparing clinical and echocardiographic outcomes following valve-sparing versus transannular patch repair of tetralogy of Fallot: a systematic review and meta-analysis. INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2024; 39:ivae124. [PMID: 38924512 PMCID: PMC11283307 DOI: 10.1093/icvts/ivae124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 06/05/2024] [Accepted: 06/25/2024] [Indexed: 06/28/2024]
Abstract
OBJECTIVES Transannular patch (TAP) repair of tetralogy of Fallot (ToF)relieves right ventricular tract obstruction but may lead to pulmonary regurgitation. Valve-sparing (VS) procedures can avoid this situation, but there is a potential for residual pulmonary stenosis. Our goal was to evaluate clinical and echocardiographic outcomes of TAP and VS repair for ToF. METHODS A systematic search of the PubMed, Embase, Scopus, Cochrane Central Register of Controlled Trials and Web of Science databases was carried out to identify articles comparing conventional TAP repair and VS repair for ToF. Random-effects models were used to perform meta-analyses of the clinical and echocardiographic outcomes. RESULTS Forty studies were included in this meta-analysis with data on 11 723 participants (TAP: 6171; VS: 5045). Participants who underwent a VS procedure experienced a significantly lower cardiopulmonary bypass time [mean difference (MD): -14.97; 95% confidence interval (CI): -22.54, -7.41], shorter ventilation duration (MD: -15.33; 95% CI: -30.20, -0.46) and shorter lengths of both intensive care unit (ICU) (MD: -0.67; 95% CI: -1.29, -0.06) and hospital stays (MD: -2.30; 95% CI: [-4.08, -0.52). There was also a lower risk of mortality [risk ratio: 0.40; 95% CI: (0.27, 0.60) and pulmonary regurgitation [risk ratio: 0.35; 95% CI: (0.26, 0.46)] associated with the VS group. Most other clinical and echocardiographic outcomes were comparable in the 2 groups. CONCLUSIONS This meta-analysis confirms the well-established increased risk of pulmonary insufficiency following TAP repair while also demonstrating that VS repairs are associated with several improved clinical outcomes. Continued research can identify the criteria for adopting a VS approach as opposed to a traditional TAP repair.

Abstract
Introduction: The pulmonic valve-sparing technique (PVS) is an emerging approach of right ventricular outflow tract reconstruction in tetralogy of Fallot (TOF) correction aimed at reducing the incidence of pulmonic regurgitation (PR) and the need for subsequent reintervention. This study aims to compare the long-term occurrence of moderate to severe PR/stenosis (PR/PS) between three different approaches. Patients and Methods: We conducted a retrospective cohort study involving 173 patients who underwent TOF correction at Chiang Mai University hospital between January 2006 and December 2016. The patients were divided into three groups: transannular patch (TAP; n = 88, 50.9%), monocusp insertion (MCI; n = 40, 23.1%), and PVS (n = 45, 26%). The study assessed freedom from moderate to severe PR/PS. Results: The median overall follow-up time was 79.8 months (interquartile range: 50.7-115.5 months. The PVS exhibited larger PV Z-score (-2.6 ± 2.3 mm, P < .001), with predominantly tricuspid morphology (64.4%). The PVS had significantly shorter median ventilator time, intensive care unit stay, hospital stay, and longer median follow-up time. Postoperative moderate-severe PR was lower in the PVS group (P < .001), with no significant difference in PS (P = .356) and complications among the groups. Freedom from moderate-severe PR/PS was longer in the MCI group (2.8, 0.2-42.3 months vs 30.9, 0.2-50.9 months, respectively). Multivariable analysis showed TAP and MCI had a higher risk of developing moderate-severe PR (hazard ratio [HR] 2.51; 95% confidence interval [CI] 1.23-5.13 vs HR 1.41; 95%CI 0.59-3.38) but lower risk of moderate-severe PS (HR 0.14; 95%CI 0.02-0.9 vs HR 0.39; 95%CI 0.05-3.19). Conclusion: Pulmonic valve-sparing reconstruction showed promise in preventing late moderate-severe PR in patients with favorable PV anatomy. However, it should be noted that this technique is associated with a higher incidence of PS.

Abstract
OBJECTIVES Pulmonary valve-sparing repair of tetralogy of Fallot and double outlet right ventricle with pulmonary stenosis has the advantage of reduced incidence of late pulmonary valve regurgitation and better-preserved cardiac function. However, a right ventriculotomy is sometimes necessary in order to adequately relieve subvalvular pulmonary stenosis. We aimed to compare postoperative cardiac function and patients' symptoms between pulmonary valve-sparing repair with and without right ventriculotomy. MATERIALS AND METHODS We retrospectively collected data from electronic medical records of Ramathibodi Hospital from 1st January 2013 to 31st October 2023. Patients diagnosed with tetralogy of Fallot and double outlet right ventricle with pulmonary stenosis who underwent pulmonary valve-sparing repair were included. Patients who underwent other types of repairs and whose medical record data were significantly missing were excluded. Demographic data, operative, and postoperative details were collected and reviewed. RESULTS There were 49 patients included in our study with 10 patients undergoing pulmonary valve-sparing repair with and the other 39 without right ventriculotomy. Before-discharge echocardiographic parameters were generally similar between both groups (tricuspid annular plane systolic excursion = 0.9 versus 0.89 cm, P = 0.737; pressure gradient across pulmonary valve across pulmonary valve = 24 versus 19 mmHg, P = 0.275; left ventricular end-systolic volume index = 17.84 versus 19.19 ml/m2, P = 0.437; left ventricular end-diastolic volume index = 63.79 versus 61.13 ml/m2, P = 0.436). Patients' symptoms were also not statistically different. There was no early and late death up to the end date of our study. CONCLUSIONS Right ventriculotomy in pulmonary valve-sparing repair did not result in worse postoperative cardiac function and symptoms. This suggested that the previously thought-to-be hazardous incision could be strongly considered if mandated.

Abstract
BACKGROUND The z-scoring system shows the mean deviation of cardiac dimensions from age-specific population. The use of the European-based z-score studies has resulted in misdiagnosis and late treatment of Nigerian children with heart diseases leading to increased mortality and morbidity. OBJECTIVES This study aimed to determine the z‑scores for various cardiac structures and functions among healthy children in Southeast Nigeria. MATERIALS AND METHODS This is a cross-sectional observational study where z-scores of the cardiac structure and function of three hundred healthy children were estimated using echocardiography and compared with the standard Detroit values. RESULT There was a significant positive correlation between age and cardiac valve diameter. The aortic valve strongly correlated positively with age with the Pearson correlation coefficient (ρ) of 0.8 and probability value (P-value) of 0.00. None of the ventricular function variables deviated beyond the +2 or -2 z-score. There was a positive correlation between the z-scores of ventricular function parameters and participants' age, although the strength of the correlation varied. Comparing these values with that of Detroit values, there was a significant difference in the deviation of the mean of the mitral valve and left pulmonary artery diameters from the Detroit values between the males and the females. While the mean z-score mitral valve was 0.8 in males, it was 0.6 in females (P = 0.02). CONCLUSION Z-scores of cardiac structures and function are derived from children in this locale. These values were similar to that of Detroit values except for the mitral valve and left pulmonary artery.

Abstract
Tetralogy of Fallot is a cyanotic congenital heart disease, for which various surgical techniques allow patients to survive to adulthood. Currently, the natural history of corrected tetralogy of Fallot is underlined by progressive right ventricular (RV) failure due to pulmonic regurgitation and other residual lesions. The underlying cellular mechanisms that lead to RV failure from chronic volume overload are characterized by microvascular and mitochondrial dysfunction through various regulatory molecules. On a clinical level, these cardiac alterations are commonly manifested as exercise intolerance. The degree of exercise intolerance can be objectified and aid in prognostication through cardiopulmonary exercise testing. The timing for reintervention on residual lesions contributing to RV volume overload remains controversial; however, interval assessment of cardiac function and volumes by echocardiography and magnetic resonance imaging may be helpful. In patients who develop clinically important RV failure, clinicians should aim to maintain a euvolemic state through the use of diuretics while paying particular attention to preload and kidney function. In patients who develop signs of cardiogenic shock from right heart failure, stabilization through the use of inotropes and pressor is indicated. In special circumstances, the use of mechanical support may be appropriate. However, cardiologists should pay particular attention to residual lesions that may impact the efficacy of the selected device.

Abstract
Certain aspects of the treatment of tetralogy of Fallot (TOF) repair remain controversial. The optimal timing of the elective repair of asymptomatic patients and the ideal strategy for managing symptomatic neonates and infants with TOF are still debated despite years of experience in TOF treatment. In this article, we discuss why a surgical correction at 3-6 months of age is likely the ideal time frame for the elective repair of TOF. We also elaborate on our strategy for managing symptomatic neonates and infants with TOF and why we prefer an early single-stage primary repair.

Abstract
Objectives The size of the pulmonary valve annulus often determines the feasibility of pulmonary valve preservation at the time of intracardiac repair of Tetralogy of Fallot. Currently, there is limited available data regarding the growth pattern and the determining factors that contribute towards pulmonary valve annulus growth. Methods This retrospective study included patients who underwent surgical repair of Tetralogy of Fallot with or without prior palliation. These patients had an echocardiogram at the time of initial diagnosis and a second echocardiogram prior to intracardiac repair. The sizes of the pulmonary annulus, the right and left pulmonary arteries with z-scores were recorded. Patients with improvement in the pulmonary annulus z-scores between the 2 echocardiographic examinations were allocated in Group I (n = 46) and Group II (n = 68) were those with no improvement. Results A total of 114 patients were included in the study. The right and left pulmonary arteries size and z scores improved significantly between the 2 echocardiograms. Although the median size of the pulmonary annulus increased between the 2 echocardiograms (6 and 7.9 mm; P<0.001), there was no significant change in the z-score (-2.2, -2.34; P = 0.185). Multivariate logistic regression analysis showed that gender, blood group, presence of collaterals, and palliation with Blalock-Taussig shunt had no impact on the improvement in pulmonary annulus z-score. Conclusion In Tetralogy of Fallot, the pulmonary valve annulus z-score may not change significantly prior to the intracardiac repair. Although in certain subgroups there may be an improvement, there was no specific factor that could be identified and had an influence on this improvement.

Abstract
OBJECTIVES To assess temporal changes in the surgical management of patients with tetralogy of Fallot including the timing of interventions, surgical techniques, reinterventions and survival in a nationwide cohort. METHODS Patients with tetralogy of Fallot in Denmark were divided into 3 eras based on their year of birth: early (1977-1991), intermediate (1992-2006) and late (2007-2021). RESULTS The cohort consisted of 745 patients. Median follow-up was 21.2 years (13.7-30.5). There was a temporal trend towards less shunt palliation (-0.3% per year, 95% CI -0.05 to -0.1). Median age at intracardiac repair was 2.9 years (1.8-5.0), 0.8 years (0.5-1.3) and 0.5 years (0.4-0.7) (P < 0.001) in the early, intermediate and late era, respectively. There was a temporal trend towards less valve-sparing repair (-0.7% per year, 95% CI -0.5 to -1.0) and more repair with transannular patches (0.7% per year, 95% CI 0.5-1.0). Survival at 10 years was 79% (64-76), 90% (87-93) and 95% (92-98) (P < 0.001) and pulmonary valve replacement within the first 10 years after intracardiac repair was performed in 3% (1-6), 12% (8-16) and 21% (13-29) (P < 0.001) in the early, intermediate and late era, respectively. CONCLUSIONS There was a temporal trend towards less shunt palliation and intracardiac repair at a younger age with more use of transannular patches. While survival throughout childhood and adolescence has improved, more patients undergo pulmonary valve replacement during the first 10 years after intracardiac repair.

Abstract
BACKGROUND We sought to compare outcomes for infants with tetralogy of Fallot with pulmonary atresia (TOF/PA) and confluent pulmonary arteries who underwent staged or primary complete surgical repair. METHODS This retrospective study included infants undergoing initial surgical intervention between 0 and 60 days of age with TOF/PA without aortopulmonary collaterals from 2009 to 2018 at 20 centers. The primary outcome was days alive and out of the hospital in the first year of life (DAOH365). Secondary outcomes were mortality at 1 year of age and a composite major complication outcome. Multivariable modeling with generalized estimating equations were used to compare outcomes between groups. RESULTS Of 221 subjects, 142 underwent staged repair and 79 underwent primary complete repair. There was no significant difference in median DAOH365 between the staged and primary repair groups (317 days [interquartile range, 278-336] vs 338 days [interquartile range, 314-348], respectively; adjusted P = .13). Nine staged repair patients (7%) died in the first year of life vs 5 primary repair patients (6%; adjusted odds ratio, 1.00; 95% CI, 0.25-3.95). At least 1 major complication occurred in 37% of patients who underwent staged repair vs 41% of patients who underwent primary complete repair (P = .75), largely driven by the need for unplanned cardiac reinterventions. CONCLUSIONS For infants with TOF/PA with confluent pulmonary arteries, a surgical strategy of staged or primary complete repair resulted in statistically similar DAOH365, early mortality, and morbidity.

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 Tetralogy of Fallot (TOF) repair is a frequent procedure, and although valve-sparing (VS) repair is preferred, determining which patients can successfully undergo this operation remains controversial. We sought to identify parameters to determine a selective, accurate indication for VS repair. METHODS We reviewed 71 patients (82%) undergoing VS repair. We analyzed hemodynamic data, intraoperative reports, and follow-up echocardiography results to identify acceptable indications. Patients requiring pulmonary valve (PV) reintervention versus no reintervention were compared. RESULTS PV annulus size at repair was z-score of -2.0 (-5.3, 1.3). Approximately half (51%) had a z-score less than -2. Cox regression results showed this was not a risk factor for reintervention (p = .59). Overall, 1-, 3-, 5-, and 10-year freedom from PV reintervention rates were 95.8%, 92.8%, 91% and 77.8%, respectively. Residual pulmonary stenosis (PS) at initial repair was relatively higher in the reintervention group compared with no reintervention group (40 [28, 51] mmHg vs. 30 [22, 37] mmHg; p = .08). For patients with residual PS, pressure gradient (PG) was consistent over time across both groups (PV reintervention: -3 [-15, 8] mmHg vs. no reintervention: 0 [-9, 8] mmHg). The risk of PV reintervention is 3.7-fold higher when the PG from intraoperative TEE is greater than 45 mmHg (p = .04). CONCLUSIONS Our review of the midterm outcomes of expanded indication for VS suggests intraoperative decision to convert to transannular patch is warranted if intraoperative postprocedure TEE PG is greater than 45 mmHg or RV pressure is higher than half of systemic pressure to prevent reintervention.

Abstract
Abstract
Background
Traditionally, the pulmonary valve annulus (PVA) z-score is used to predict the requirement of transannular patch enlargement (TAPE) of right ventricular outflow tract (RVOT) and main pulmonary artery (MPA) in repair of tetralogy of Fallot (TOF). PVA z-score is highly variable and many other parameters are being reported to be accurate in predicting need of TAPE. In this study, we analyze the role of great artery annulus ratio (pulmonary valve annulus to aortic valve annulus ratio, PVA/AVA) to be used as a predictor for TAPE.
Methods
We analyzed 90 patients of TOF retrospectively who underwent repair between January 2021 and December 2021. The patients were divided as TAPE group who required TAPE of RVOT and MPA and non-TAPE group who did not have TAPE. Their baseline parameters, PVA Z-score, and cut-off great artery annulus ratio were compared.
Results
Total 44 (48.9%) patients had transannular patch (TAPE) repair and 46 (51.1%) patients had non-transannular patch repair. The great artery annulus ratio and PVA z-score was lower in case of TAPE group with statistical significance. Receiver operating characteristic curve analysis showed great artery annulus ratio as more accurate predictor of TAPE.
Conclusion
Great artery annulus ratio can be used as a simple and accurate predictor for transannular patch enlargement along with PVA z-score during repair of TOF.

Abstract
Tetralogy of Fallot (TOF) is a common cyanotic congenital heart disease. Its surgical correction requires ventricular septal defect (VSD) closure and right ventricular outflow tract obstruction (RVOTO) relief, with transannular patch enlargement (TAPE) of the pulmonary valve. The first successful repair of TOF was reported in 1954 and consisted of closure of the VSD through a large right ventriculotomy, and RVOTO relief with TAPE of the pulmonary valve. To predict the intraoperative requirements and postoperative course of patients with this condition, various evaluation indices are available that can provide a good indication of patient prognosis. We performed this study in a male child (age, 1 year, 9 months; weight 8.5 kgs.) who underwent intracardiac repair for TOF as a primary procedure. We calculated the pulmonary vein index (PVI), McGoon ratio, and Nakata index. The McGoon ratio was 1.97, Nakata index was 539.22 mm2/m2, and PVI was 368.12 mm2/m2. The child had an uneventful post-operative course with no symptoms of low cardiac output syndrome. He was ventilated for 122 h. The length of intensive care unit and hospital stays were 11 and 14 days, respectively. The PVI is a novel indicator offering prognostic indications for pediatric cardiac patients who have undergone surgical correction of TOF.

Abstract
OBJECTIVES To figure out the optimal strategy to manage Tetralogy of Fallot (TOF) with unbalanced pulmonary artery(PA) branches by investigating the different effects of PA plasty on the development of the hypoplastic PA (HPA). METHODS A single center, retrospective analysis was carried out to compare the outcome of different PA plasty methods on the development of HPA in patients of TOF with unbalanced PA branches. Size and balance of the PA branches were used to evaluate the outcome of PA plasty. RESULTS In the NATIVE group, 100% of the HPAs were well-developed and all the PA branches became balanced, while in the PATCH and EXTENSION groups, the percentage of well-developed HPAs was 40% and 33%, respectively, and none of the PA branches were balanced. In addition, HPAs became atretic in 28% of the patients in the patch enlargement group. CONCLUSIONS For TOF with unbalanced PA branches, patch enlargement may not be a good treatment strategy, as it reduces the growth potential of HPA and even causes iatrogenic atresia. Leaving the HPA in the native state without patch enlargement may be a good strategy.

Abstract
Objective: The study aims to establish a new method in the Tetralogy of Fallot (ToF) called the pulmonary valve bi-orifice method (pulmonary annular sparing with an individualized autologous pericardial patch; thus, two orifices are formed at the level of the pulmonary valve annulus) to reconstruct the right ventricular outflow tract (RVOT). Methods: A retrospective analysis of 128 TOF patients from October 2009 to June 2018 with severe pulmonary valve dysplasia who underwent transvalvular annular patch (TAP) procedure (control group) or an individualized pulmonary valve bi-orifice procedure (observation group) were studied. The RVOT for each patient in the observation group was individually reconstructed per the patient's weight and the size of the autologous pulmonary valve using the bi-orifice method; however, increasing the cross-sectional area of the pulmonary valve annulus without destroying its integrity. The result was then compared to the control group, where TAP procedures were applied to evaluate the short to mid-term outcome(s). An in vitro simulation test was used to verify the anti-regurgitation mechanism of the new method. Results: The in vitro simulation test indicated that the anti-regurgitation mechanism was completed by the pericardial patch and the autologous pulmonary valve movement toward each other. Thus, for clinical applications, patients in both groups were compared. The results showed no significant differences in cardiopulmonary bypass and aortic cross-clamp time, mechanical ventilation, and ICU and post-operative residence between the two groups. During the follow-up period (3- to 12-years), 14 patients in the observation group had mild regurgitation after surgery (22.2%), while 10 patients had moderate pulmonary regurgitation (15.8%) with no right ventricular (RV) dilation. On the other hand, 22 patients (39.6%) had moderate to severe regurgitation in the control group, while left pulmonary artery stenosis occurred in one patient. In the control group, six patients (9.2%) with severe RV dilation were reoperated. Conclusion: Individualized pulmonary valve bi-orifice procedure is a safe and excellent method for reconstructing RVOT in ToF.

Abstract
Background : During repair of tetralogy of fallot (TOF) we modified surgical strategies to preserve the valve and annulus if the pulmonary valve leaflets are pliable and not significantly dysplastic. Methods : Initially, the repair was done from the main pulmonary artery (Group-1, 215 patients) and later through an additional incision in the infundibulum of the right ventricle (Group-2, 73 patients). Recently, we changed the approach to commissurotomy of the fused leaflets by releasing the supra valvar tethering and delamination of the cuspal apparatus till the base to improve the mobility of the cusps and do a controlled commissurotomy (Group-3, 14 patients). With delamination, we could extend the limit of the repair to a z-score of –3.5. Results : There was no hospital mortality; two patients died at home after discharge. A mean follow-up of 42.01 months ± 19.25 is available for 198 patients (92%) for group 1, 16.03 ± 7.45 for group 2, and 4.07 ± 2.09 for group 3. The re-intervention-free survival is 94.4% in group 1. The z value improved from -3 (-3–-2) to -1.2 (-3 – 0), P = 0.001 in Group 1, from -2.8 (-3–-2.4) to -1 (-1.1–-0.7), P = 0.001 in Group 2 and from –3 (-4–-3) to -1, P = 0.001 in Group 3. In all the groups, there was trivial or mild pulmonary regurgitation. Conclusions : During repair of TOF, adequate valve/annulus sparing is possible if the repair is done from both the main pulmonary artery and infundibular incisions using the delamination technique.

Abstract
BACKGROUND Although valve-sparing repair remains ideal for patients with tetralogy of Fallot, the durability of valve-sparing repair and which patients may have been better served with a transannular patch remain unclear. METHODS Retrospective review was performed of tetralogy of Fallot operations at our institution from January 2008 to December 2018. Standard demographic data were collected, including echocardiographic parameters, operative details, and clinical outcomes. Statistical analysis was performed comparing the transannular patch and valve-sparing repair groups. RESULTS Sixty-seven patients underwent tetralogy of Fallot repair with a median age of 4.5 (3.2-6.0) months and weight of 5.8 (5.2, 6.7) kg. Seventeen (25%) patients underwent transannular patch repair and 50 (75%) patients underwent valve-sparing repair. There was no difference in age or weight between patients who underwent a transannular patch repair and those who underwent a valve-sparing repair. At last follow-up (median 42 months), there was a trend of a higher peak pulmonary valve/right ventricular outflow tract gradient (P = .06) in the valve-sparing group, but no difference in the pulmonary valve annulus z-scores. Additionally, the pulmonary valve z-scores in the valve-sparing group decreased from -2.3 ± 1.0 on predischarge echocardiogram of to -1.2 ± 1.6 on last follow-up, with the peak gradient on predischarge 23 (0-37) mm Hg remaining stable on last follow-up at 18 (0-29) mm Hg. There was one reoperation: pulmonary valve replacement six years after a transannular patch. CONCLUSIONS Obtaining a postrepair pulmonary valve z-score of -2 yields satisfactory, stable valve-sparing repair with pulmonary valve growth, acceptable gradients, minimal regurgitation, and high freedom from reintervention during follow-up.

Front Cardiovasc Med 2021; 8:695876. [PMID: 34422925 PMCID: PMC8372408 DOI: 10.3389/fcvm.2021.695876] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 07/12/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Current observational studies may not have large samples to investigate the relationship between pulmonary valve (PV) morphology differences and outcomes after complete repair for tetralogy of Fallot (TOF) by right ventricular outflow tract (RVOT) incision. This study aimed to assess the impact of PV morphology differences on outcomes after complete repair for TOF. Methods: This is a retrospective cohort study. Consecutive patients who underwent TOF repair with RVOT incision at Fuwai Hospital from January 2012 to December 2017 were included and compared according to PV morphology differences (unicuspid or bicuspid was abnormal morphology, while the tricuspid valve was normal morphology). The primary outcome was defined as a composite of death, or reintervention, or significant annular peak gradient (APG), or significant pulmonary regurgitation (PR), whichever occurred first. Multivariable Cox model analysis was used to assess the relationships between PV morphology differences and outcomes. Subgroup analysis and Propensity-score analysis were performed as sensitivity analyses to assess the robustness of our results. Results: The cohort included a total of 1,861 patients with primary diagnosis of TOF, with 1,688 undergoing CR-TOF with RVOT incision. The median age was 318 days [interquartile range (IQR): 223-534 days], a median weight of 8.9 kg (IQR: 7.6-10.5 kg) and 60.0% (1,011) were male. Complete follow-up data were available for 1,673 CR-TOF patients with a median follow-up duration of 49 months. Adjusted risks for the primary outcome and significant APG were lower for patients with normal PV morphology at follow up [adjusted hazard ratio (HR): 0.68; 95% CI: 0.46-0.98; adjusted HR: 0.22; 95% CI: 0.07-0.71, respectively]. The trend for the primary outcome during follow-up remained unchanged, even in subgroups and propensity score matching analyses. Conclusions: In this analysis of data from a large TOF cohort, patients with normal tricuspid PVs were associated with a decreased risk of the primary outcome and a lower risk of significant APG, as compared with patients with abnormal unicuspid or bicuspid PVs.

Pulmonary valve replacement may not restore ventricular volume and functional status in patients with pulmonary regurgitation after late tetralogy of Fallot repair. Eur J Cardiothorac Surg 2021; 61:64-72. [PMID: 34254142 DOI: 10.1093/ejcts/ezab277] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 04/12/2021] [Accepted: 04/30/2021] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Clinically, tetralogy of Fallot (TOF) patients who underwent repair late (older than 2 years) appears to have worse outcomes after pulmonary valve replacement than patients who underwent repair early. We proceeded to review the clinical features of late-repaired TOF patients who required pulmonary valve replacement. METHODS Fifty patients who underwent pulmonary valve replacement after TOF repair over the age of 2 years from 2000 to 2018 were retrospectively reviewed. Pre- and postoperative cardiac magnetic resonance imaging, cardiopulmonary exercise tests, and cardiac catheterization were analysed. RESULTS The median age of patients at the time of TOF repair and pulmonary valve replacement was 3.6 and 23.4 years, respectively. The median interval from TOF repair to pulmonary valve replacement was 20.5 years. Cardiac magnetic resonance imaging and cardiopulmonary exercise tests were performed at a median of 5.9 and 3.7 years after pulmonary valve replacement, respectively. Cardiac magnetic resonance revealed that there were significant changes in the indexed values of the right ventricle end-diastolic volume (164.7-106.9 ml/m2, P < 0.001), end-systolic volume (101.4-64.9 ml/m2, P < 0.001), stroke volume (66.8-48.0 ml/m2, P = 0.007) and cardiac output (5.1-3.6 l/m2, P = 0.040). Twenty-eight percentage of patients achieved normalization of the right ventricular volume after pulmonary valve replacement. In the exercise test, the maximum rate of oxygen consumption (72.5-69.5%) and oxygen pulse (95.0-83.0%) changed without statistical significance. CONCLUSIONS Although pulmonary valve replacement after late TOF correction improves right ventricular volume status, only a minority of patients achieve normalization of right ventricular end systolic volume and a normal functional status.

JAMA Netw Open 2021; 4:e2118141. [PMID: 34313740 PMCID: PMC8317016 DOI: 10.1001/jamanetworkopen.2021.18141] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/01/2023] Open
Abstract
IMPORTANCE The choice of the right surgical technique for correction of tetralogy of Fallot (TOF) is contentious for patients with a moderate to severe right outflow tract obstruction. The use of a transannular patch (TAP) exposes patients to chronic pulmonary regurgitation, while valve-sparing (VS) procedures may incompletely relieve pulmonary obstruction. OBJECTIVE To compare 30-year outcomes of TOF repair after a VS procedure vs TAP. DESIGN, SETTING, AND PARTICIPANTS This retrospective population-based cohort study was conducted among all patients with TOF born in the province of Quebec, Canada, from 1980 to 2015 who underwent complete surgical repair. Patients who received a TAP or VS procedure were matched using a propensity score based on preoperative factors in a 1:1 ratio. Data were analyzed from March 2020 through April 2021. EXPOSURES The study groups were individuals who received TAP and those who received VS. The VS group was further stratified by the presence of residual pulmonary stenosis. MAIN OUTCOMES AND MEASURES The primary outcome was all-cause mortality, with 30-year survival evaluated using Cox proportional-hazards models. Secondary outcomes included the cumulative mean number of cardiovascular interventions, pulmonary valve replacements (PVRs), and cardiovascular hospitalizations were evaluated using marginal means/rates regressions. RESULTS Among 683 patients with TOF (401 patients who underwent TAP [58.7%] and 282 patients who underwent a VS procedure [41.3%]), adequate propensity score matching was achieved for 528 patients (264 patients who underwent a VS procedure and 264 patients who underwent TAP). Among this study cohort, 307 individuals (58.1%) were men. The median (interquartile range [IQR]) follow-up was 16.0 (8.1-25.4) years, for a total of 8881 patient-years, including 63 individuals (11.9%) followed up for more than 30 years. Individuals who received a VS procedure had an increased 30-year survival of 99.1% compared with 90.4% for individuals who received TAP (hazard ratio [HR], 0.09 [95% CI, 0.02-0.41]; P = .002). Patients who underwent TAP had an increased 30-year cumulative mean number of cardiovascular interventions compared with patients who underwent a VS procedure without residual pulmonary stenosis (2.0 interventions [95% CI, 1.5-2.7 interventions] vs 0.7 interventions [95% CI, 0.5-1.1 interventions]; mean ratio [MR], 0.36 [95% CI, 0.25-0.50]; P < .001) and patients who underwent a VS procedure with at least moderate residual stenosis (1.3 interventions [95% CI, 0.9-1.9 interventions]; MR, 0.65 [0.45-0.93]; P = .02). Results were similar for PVR, with a 30-year cumulative mean 0.3 PVRs [95% CI, 0.1-0.7 PVRs] for patients who underwent a VS procedure without residual pulmonary stenosis (MR, 0.22 [95% CI, 0.12-0.43]; P < .001) and 0.6 PVRs (95% CI, 0.2-1.5 PVRs) for patients with at least moderate residual stenosis (MR, 0.44 [95% CI, 0.21-0.93]; P = .03), compared with 1.4 PVRs (95% CI, 0.8-2.5 PVRs) for the TAP group. No statistically significant difference was found for cardiovascular hospitalizations. CONCLUSIONS AND RELEVANCE This study found that patients who underwent a VS procedure had increased 30-year survival, fewer cardiovascular reinterventions, and fewer PVRs compared with individuals who underwent TAP, even in the presence of significant residual pulmonary stenosis. These findings suggest that it is beneficial to perform a VS procedure when possible, even in the presence of moderate residual stenosis, compared with the insertion of a TAP.

Abstract
BACKGROUND Great variability exists in repair strategies for the tetralogy of Fallot. While transannular patching, as introduced by Kirklin, was a breakthrough for primary repair, pulmonary regurgitation and a need for reoperation have led to the development of methods that preserve the natural morphology of the right ventricular outflow tract. METHODS State-of-the-art details of tetralogy of Fallot repair are explained from the standpoint of architectural preservation, especially with regard to sparing native tissue such as the annulus, valve, or infundibulum. Particular attention is given to the latest technical details of each approach, benefits and disadvantages, and any long-term data available. RESULTS The choice of procedure is complex and unique to each case as transannular patching alone may carry long-term pulmonary risks. Modifications that spare the annulus, valves, or infundibulum may thus be essential as preservation of natural morphology has resulted in excellent mid-term results. CONCLUSIONS The complexity of tetralogy of Fallot repair demands constant attention to clinical presentation and vigilance against long-term sequelae. Techniques will continue to improve over time as long-term data guides the refinement of these innovative surgical methods.

Abstract
During transatrial-transpulmonary repair of tetralogy of Fallot, one of the challenges is accurately sizing the right ventricular (RV) outflow tract diameter, including the pulmonary annulus in an antegrade manner through the right atrium. This is due to the almost 90° angle between the long axis of the RV inflow through the tricuspid valve and the RV outflow through the pulmonary valve. The angled Hegar dialator, helps to accurately size the right ventricular outflow tract from the right atrium through the tricuspid valve in an antegrade manner.

Abstract
Today, strategy of repair remains controversial and rare analyses on annular integrity associated with outcomes in complete repair by RVOT incision were performed in a large TOF cohort in China. This is a retrospective cohort study involving patients with TOF who had undergone complete repair by RVOT incision between January 2012 and December 2017 in Fuwai hospital. The primary outcome was a composite of reintervention, significant pulmonary regurgitation (PR) and significant annular peak gradient (APG). Multivariate Cox proportional-hazards model analyses were used to assess the relationships between annular integrity and outcomes. In total, 1673 survival patients with the median age of 318 days were included, and 1002 were male. During a median follow-up of 49 months, 538 participants developed the primary outcome (27 reinterventions). Multivariate Cox analyses showed that compared with AS, TAP was associated with an increased risk of primary outcome (adjusted HR, 1.94 [95% CI 1.60-2.37]) and the results remained unchanged even in most subgroups defined. In secondary outcomes analyses, TAP is associated with a higher risk of reintervention (adjusted HR, 3.32 [95% CI 1.25-8.79]) and significant PR (adjusted HR, 2.51 [95% CI 2.00-3.16]). However, TAP is not associated with a decreased risk of significant APG (adjusted HR, 1.33 [95% CI 0.94-1.88]). PVA integrity preservation is important in complete repair of TOF with RVOT incision. TAP is associated with a higher risk of reintervention and significant PR, and with a similar risk of significant APG. Significant APG in AS patients at discharge has a downtrend over time.

Abstract
OBJECTIVE This study sought to investigate the variation of right heart structure pre- and post-operation as risk factors for moderate to severe pulmonary regurgitation (PR) after repaired Tetralogy of Fallot and the best "cutoff" values for the transannular patch (TAP). METHODS We collected surgical, echocardiographic, and computed tomographic data of Teralogy of Fallot (TOF) patients over two years and calculated z-score values based on the echocardiographic data. Based on the PR level after follow-up, the patients were divided into two groups, trivial to mild PR and moderate to severe PR. A multivariate logistic regression analysis was performed, and the receiver operating characteristic curve analysis was used to find the best "cutoff" value for risk factors. RESULTS A total of 104 TOF patients were included in our cohort study. From the multivariate analysis, correction strategy (P = .002), difference in zRVOT (OR 1.974, 95% CI 1.354 to 2.878, P < .0001), and zPVA (OR 3.605, 95% CI 1.980 to 6.562, P < .0001) were the significant risk factors for moderate to severe PR. The "cutoff" value for the difference in zPVA that could predict moderate to severe PR in the TAP group was 3, and the optimal "cutoff" value for TAP was -1.4. CONCLUSIONS The TAP is a risk factor for significant PR after surgery. We recommend the optimal "cutoff" value for TAP is -1.4 calculated using Shan-Shan Wang's data set. During the procedure, to limit the RVOT resection and restrict the enlargement of pulmonary annulus within a variation of z-score as 3 would reduce significant PR.

Abstract
BACKGROUND The en bloc rotation of the outflow tracts is a surgical option for anatomic repair of transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction with preserved growth potential in all tubular structures and the option for keeping the native pulmonary valve. The aim of this study was to analyze our 15-year experience with this operation. METHODS A retrospective single-center study including 27 consecutive patients, who underwent the en bloc rotation between 2003 and 2019, was performed. Median age at operation was 103 days (interquartile range [IQR], 17-117 days), and median body weight was 5.2 kg (IQR, 3.66-8.4 kg). Six patients had undergone 1 to 4 previous operations. In 18 patients (66.7%), the pulmonary valve could be preserved, and in 9 patients (33.3%) a transannular patch was performed. Median follow-up was 5.7 years (IQR, 1.6-9.0 years). RESULTS One patient died of chronic left ventricular failure during the hospital stay. Two more died after discharge: 1 of aspiration after a cerebral hemorrhage and 1 of sudden death. Five other patients required reoperations or had reinterventions: 1 ventricular septal defect closure, 1 aortic valve repair, 1 patch plasty, 2 dilatations of supravalvular pulmonary stenosis, and 1 stent into a left pulmonary artery. During the follow-up period, no gradient in the left ventricular outflow tract was found, and postoperative growth of the pulmonary valve was shown. CONCLUSIONS The en bloc rotation allows an anatomic correction of the complex transposition with growth potential in all tubular structures. Reoperations or reinterventions on the pulmonary valve or on the left ventricular outflow tract have not been necessary to date.

Abstract
BACKGROUND A certain degree of pulmonary stenosis after total correction of tetralogy of Fallot has been considered acceptable. But the long-term outcomes are not well understood. We observed the natural course of immediate pulmonary stenosis and investigated related factors for progression. METHODS Fifty-two patients with acceptable pulmonary stenosis immediately after operation were enrolled. Acceptable pulmonary stenosis was defined as peak pressure gradient between 15 and 45 mmHg by Doppler echocardiography. Latent class linear mixed model was used to differentiate patients with progressed pulmonary stenosis, and the factors related to progression were analysed. RESULTS Pulmonary stenosis progressed in 14 patients (27%). Between the progression group and no progression group, there were no significant differences in operative age, sex, and the use of the transannular patch technique. However, immediate gradient was higher in the progression group (32.1 mmHg versus 25.7 mmHg, p = 0.009), and the cut-off value was 26.8 mmHg (sensitivity = 65.3%, specificity = 65.8%). Main stenosis at the sub-valve was observed more frequently in the progression group (85.7% versus 52.6%, p = 0.027). Despite no difference in the preoperative pulmonary valve z value, the last follow-up pulmonary valve z value was significantly lower in the progression group (-1.15 versus 0.35, p = 0.002). CONCLUSIONS Pulmonary stenosis immediately after tetralogy of Fallot total correction might progress in patients with immediate pulmonary stenosis higher than ≥26.8 mmHg and the main site was sub-valve area.

Abstract
BACKGROUND There is ongoing debate about the best strategy to treat patients with tetralogy of Fallot who are symptomatic in the neonatal period. OBJECTIVES The aim of this study was to compare the outcomes of complete versus staged surgery (i.e., initial palliative procedure for possible later complete repair). METHODS A retrospective cohort study was performed using the Pediatric Health Information System database, including patients who underwent complete or staged tetralogy of Fallot repair prior to 30 days of age. The primary outcome was death during 2-year follow-up after the initial procedure. Inverse probability-weighted Cox and logistic regression models were used to examine the association between surgical approach group and mortality while accounting for patient- and hospital-level factors. Causal mediation analyses examined the role of intermediate variables. RESULTS A total of 2,363 patients were included (1,032 complete and 1,331 staged). There were 239 deaths. Complete neonatal repair was associated with a significantly higher risk for mortality during the 2-year follow-up period (hazard ratio: 1.51; 95% confidence interval: 1.05 to 2.06), between 7 and 30 days after the initial procedure (hazard ratio: 2.29; 95% confidence interval: 1.18 to 4.41), and during the initial hospital admission (odds ratio: 1.72; 95% confidence interval: 1.15 to 2.62). Post-operative cardiac complications were more common in the complete repair group and mediated the differences in 30-day and 2-year mortality. CONCLUSIONS Complete surgical repair for neonates with tetralogy of Fallot is associated with a significantly higher risk for early and 2-year mortality compared with the staged approach, after accounting for patient and hospital characteristics. Post-operative cardiac complications mediated these findings.

Abstract
BACKGROUND The decision to use transannular patching (TAP) during tetralogy of Fallot (TOF) repair depends on the pulmonary valve annulus size; the z score of the pulmonary annulus is the most commonly used predictor. However, definitive results are not obtained with z scores as different z score data sets are used for different parameters. PURPOSE This study aimed to identify the echocardiographic and other key factors that warranted a change in the surgical method during TOF surgery. METHODS Sixty-two patients were enrolled and divided into a pulmonary valve (PV) preservation group and a TAP group. Their medical records were reviewed. RESULTS The z score for PV annulus (PVA), ratio of the PVA to aortic annulus size, and ratio of PVA to descending aorta (DAO) size were significantly different between the PV preservation and TAP groups (-1.72±1.52 vs. -3.07±1.94, P=0.004; 0.62±0.12 vs. 0.50±0.14, P=0.002; and 1.32±0.32 vs. 1.07±0.36, P= 0.008, respectively). For TAP repair, the PVA z score had a sensitivity of 65.4% and specificity of 73.1%, ratio of PVA to aortic annulus size had a sensitivity of 73.1% and specificity of 65.4%, and ratio of PVA to DAO size had a sensitivity of 69.2% and specificity of 57.7%. The TAP group showed more monocuspid PVs (P=0.011), while the PV preservation group showed more tricuspid PVs (P=0.027). Commissurotomy was more frequently performed in the PV preservation group than in the TAP group (P=0.001). Of patients with commissurotomy, 58% showed a PV z score<-2. CONCLUSION Although various echocardiographic parameters may serve as predictors for determining surgical methods for TOF patients, the PV morphology and tissue characteristics should also be considered.

Abstract
BACKGROUND Early surgical tetralogy of Fallot (ToF) repair involved patching across the pulmonic annulus (transannular patch [TAP] repair), which resulted in severe pulmonic regurgitation. Long-term outcome improvements were anticipated with modifications that preserved the pulmonic annulus (annulus-preserving [AP] repair). The objective of the present study was to evaluate the need for late reintervention in adults with AP repair and those with TAP repair. METHODS We conducted a retrospective review of adults (born 1981-1996) with childhood intracardiac ToF repairs at a tertiary care center. The primary cardiovascular outcome was need for reintervention after primary intracardiac repair of ToF. Secondary outcomes included a composite of death, heart failure, and ventricular arrhythmias. RESULTS Two hundred thirty adults were included: 104 with AP repair and 126 with TAP repair. The median age at last follow up was 25 years (interquartile range [IQR] 20-28) and the median follow-up duration was 7.9 years (IQR 3.5-12). Reintervention of any type was significantly more common in the TAP group during both childhood and adulthood (72.2% TAP vs 20.2% AP, HR 5.5, 95% CI 3.4-9.0; P < 0.001). Pulmonary valve replacement (PVR) was almost 6 times more likely in adults with TAP repair (65.1% TAP vs 16.3% AP, HR 5.7, 95% CI 3.4-9.7; P < 0.001). CONCLUSIONS Patients who had AP ToF repair had significantly fewer late reinterventions compared with TAP repair, with the majority of reinterventions due to PVR. More long-term follow-up is required.

Abstract
BACKGROUND The optimal management of tetralogy of Fallot (TOF) in symptomatic neonates remains unknown. We compared outcomes for those undergoing palliation vs complete repair in the neonatal period. METHODS In a retrospective cohort study of symptomatic neonates with TOF who had a neonatal complete repair (group 1, n = 112) or staged repair (group 2, n = 26) from 2000 to 2013, we compared outcomes at 4 time points: neonatal complete repair vs palliation (group 1 vs 2A), neonatal vs later complete repair (group 1 vs 2B), the single vs combined admissions to achieve a complete repair (group 1 vs group 2A + 2B), and cumulative events 2 years after complete repair for both groups. RESULTS Demographics, anatomy, comorbidities, surgical approach, and mortality were similar between groups 1 and 2. Group 1 had a longer duration of cardiopulmonary bypass and deep hypothermic circulatory arrest and more postprocedure cardiac events compared with group 2A; a longer duration of intubation, intensive care, and postprocedure hospital stay compared with groups 2A and 2B; and a longer total hospital stay compared with group 2B. With combined admissions for group 2, there was no difference in the total duration of intensive care, total hospital stay, or reinterventions compared with group 1. CONCLUSIONS Both management options result in similar survival; however, early morbidity was greater with neonatal complete repair. The impact of increased neonatal exposures, such as cardiopulmonary bypass, deep hypothermic circulatory arrest, and intensive care, on neurocognitive development requires further study but should be considered when choosing an optimal strategy.

Abstract
BACKGROUND The optimal surgical strategy for tetralogy of Fallot (TOF) repair in neonates and young infants requiring early surgical intervention remains controversial. Our surgical center follows the uniform strategy of a staged approach with initial systemic-to-pulmonary artery shunt the majority of time when early surgical intervention is required. We characterized a contemporary cohort of patients with TOF with pulmonary stenosis (PS) undergoing staged repair in order to determine the rate of pulmonary valve-sparing repair (PVSR), growth of the pulmonary valve annulus and pulmonary arteries, postoperative morbidity and mortality, and need for reintervention. METHODS We retrospectively studied patients with TOF/PS who underwent staged repair from 2000 to 2017. Surgical details, postoperative course, and reinterventions were noted. Echocardiographic measurements and Z-score values of pulmonary valve annulus, main pulmonary artery (MPA), right pulmonary artery (RPA), and left pulmonary artery (LPA) diameters were evaluated. RESULTS Of the 59 patients with staged TOF/PS, PVSR was performed in 25 (42%). There was a 5% incidence of postoperative arrhythmia. The Z-scores of MPA, RPA, and LPA were significantly higher before complete repair when compared to before palliative shunt. The 5 and 10-year survival rates were both 93%, and the probability of freedom from reoperation at 5 and 10 years was 87% and 82%, respectively. CONCLUSIONS Staged repair of TOF in young symptomatic infants results in 42% receiving PVSR, pulmonary artery growth, low incidence of postoperative arrhythmia, and relatively low rate of reoperations.

Abstract
BACKGROUND Precisely evaluating the need for transannular patch (TAP) placement is very important in the surgical treatment of tetralogy of Fallot. We hypothesized that the pulmonary annulus area index (PAAI, the pulmonary-to-aortic valve annulus cross-sectional area ratio) could be a useful and accessible predictor for TAP placement. METHODS The medical records of patients who underwent tetralogy of Fallot repair between 1 January 2016 and 31 December 2017 were reviewed retrospectively. A total of 255 patients were included and categorized into two groups: patients who needed TAP placement and patients who did not. Various candidate predictors for TAP placement (PAAI, pulmonary annulus z-score, and velocity across the pulmonary annulus) were compared using receiver operating characteristic curves. The optimal cutoff for each predictor was assessed. RESULTS Among the 255 patients included, 156 needed TAP placement (156/237, 65.8%). Both the PAAI (0.28 [0.20/0.34] vs 0.14 [0.09/0.19]; P < .0001) and z-score (-1.5 [-2.9, -0.4] vs -3.6 [-5.3/-2.6]; P < .0001) were smaller in the TAP group. The PAAI is a useful predictor of the pulmonary annulus z-score (AUC 0.830 vs 0.811, P = .19). Combination analysis of the PAAI and velocity across the pulmonary annulus (PV vmax ) showed better predictive value than the PAAI and z-score (AUC 0.860, sensitivity 89.7%, specificity 61.7%, P < .0001). CONCLUSIONS Our results suggest that the PAAI is a useful and accessible predictor for TAP placement and can be applied readily and simply in clinical practice. A combination with the velocity across the pulmonary annulus could promote the accuracy of prediction.

Abstract
OBJECTIVES Pulmonary valve (PV) regurgitation (PR) is common after intervention for a hypoplastic right ventricular outflow tract. Secondary PV repair is an alternative to replacement (PVR), but selection criteria are not established. We sought to elucidate preoperative variables associated with successful PV repair and to compare outcomes between repair and PVR. METHODS Patients who underwent surgery for secondary PR from 2010 to 2017 by a single surgeon were studied. The PV annulus and leaflets were measured on the preoperative echocardiogram and magnetic resonance images, and the primary predictor variable was leaflet area indexed to ideal PV annulus area (iPLA) by magnetic resonance imaging. PV repair and PVR groups were compared using multivariable logistic regression, and with a conditional inference tree. Freedom from PV dysfunction and from reintervention were assessed with Kaplan-Meier survival analyses. RESULTS Of 85 patients, 31 (36%) underwent PV repair. By multivariable analysis, longer PV total leaflet length (cm/m2) (β = 3.00, standard error [SE] = 0.82, P < .001), larger PV z score (β = 1.34, SE = 0.39, P = .001), and larger iPLA (β = 8.13, SE = 2.62, P = .002) were associated with repair. iPLA of 0.90 or greater was 91% sensitive and 83% specific for achieving PV repair. At a median of 4.1 years follow-up, there was greater freedom from significant PR in the PV repair group (log rank P = .008). CONCLUSIONS Patients with an iPLA >0.9, and those with an iPLA between 0.7 and 0.9 with a PV annulus z score >0 should be considered for a native PV repair. At midterm follow-up, patients with a PV repair were not more likely to develop PR or to require reintervention when compared with patients undergoing PVR.

Abstract
Tetralogy of Fallot (ToF) is the most common type of cyanotic congenital heart disease. Since the first surgical repair in 1954, treatment has continuously improved. The treatment strategies currently used in the treatment of ToF result in excellent long-term survival (30 year survival ranges from 68.5% to 90.5%). However, residual problems such as right ventricular outflow tract obstruction, pulmonary regurgitation, and (ventricular) arrhythmia are common and often require re-interventions. Right ventricular dysfunction can be seen following longstanding pulmonary regurgitation and/or stenosis. Performing pulmonary valve replacement or relief of pulmonary stenosis before irreversible right ventricular dysfunction occurs is important, but determining the optimal timing of pulmonary valve replacement is challenging for several reasons. The biological mechanisms underlying dysfunction of the right ventricle as seen in longstanding pulmonary regurgitation are poorly understood. Different methods of assessing the right ventricle are used to predict impending dysfunction. The atrioventricular, ventriculo-arterial and interventricular interactions of the right ventricle play an important role in right ventricle performance, but are not fully elucidated. In this review we present a brief overview of the history of ToF, describe the treatment strategies currently used, and outline the long-term survival, residual lesions, and re-interventions following repair. We discuss important remaining challenges and present the current state of the art regarding these challenges.

Surgical Outcomes in Syndromic Tetralogy of Fallot: A Systematic Review and Evidence Quality Assessment. Pediatr Cardiol 2019; 40:1105-1112. [PMID: 31214731 DOI: 10.1007/s00246-019-02133-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Accepted: 06/11/2019] [Indexed: 12/16/2022]
Abstract
Tetralogy of Fallot (ToF) is one of the most common cyanotic congenital heart defects. We sought to summarize all available data regarding the epidemiology and perioperative outcomes of syndromic ToF patients. A PRISMA-compliant systematic literature review of PubMed and Cochrane Library was performed. Twelve original studies were included. The incidence of syndromic ToF was 15.3% (n = 549/3597). The most prevalent genetic syndromes were 22q11.2 deletion (47.8%; 95% CI 43.4-52.2) and trisomy 21 (41.9%; 95% CI 37.7-46.3). Complete surgical repair was performed in 75.2% of the patients (n = 161/214; 95% CI 69.0-80.1) and staged repair in 24.8% (n = 53/214; 95 CI 19.4-30.9). Relief of RVOT obstruction was performed with transannular patch in 64.7% (n = 79/122; 95% CI 55.9-72.7) of the patients, pulmonary valve-sparing technique in 17.2% (n = 21/122; 95% CI 11.5-24.9), and RV-PA conduit in 18.0% (n = 22/122; 95% CI 12.1-25.9). Pleural effusions were the most common postoperative complications (n = 28/549; 5.1%; 95% CI 3.5-7.3). Reoperations were performed in 4.4% (n = 24/549; 95% CI 2.9-6.4) of the patients. All-cause mortality rate was 9.8% (n = 51/521; 95% CI 7.5-12.7). Genetic syndromes are seen in approximately 15% of ToF patients. Long-term survival exceeds 90%, suggesting that surgical management should be dictated by anatomy regardless of genetics.

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
BACKGROUND Residual right ventricular outflow obstruction during Tetralogy of Fallot repair necessitates peri-operative revision often requiring trans-annular patch with its negative sequels. Bidirectional Glenn shunt in this setting reduces trans-pulmonary gradient to avoid revision. METHODS Bidirectional Glenn shunt was added during Tetralogy repair in patients with significant residual obstruction. A total of 53 patients between January, 2011 and June, 2018 were included. Final follow-up was conducted in July, 2018. RESULTS Mean age at operation was 5.63±3.1 years. Right to left ventricular pressure ratio reduced significantly (0.91±0.09 versus 0.68±0.05; p<0.001) after bidirectional Glenn, avoiding revision in all cases. Glenn pressures at ICU admission decreased significantly by the time of ICU discharge (16.7±3.02 versus 13.5±2.19; p<0.001). Pleural drainage ≥ 7 days was seen in 14 (26.4%) patients. No side effects related to bidirectional Glenn-like facial swelling or veno-venous collaterals were noted. Mortality was 3.7%. Discharge echocardiography showed a mean trans-pulmonary gradient of 32.11±5.62 mmHg that decreased significantly to 25.64±5 (p<0.001) at the time of follow-up. Pulmonary insufficiency was none to mild in 45 (88.2%) and moderate in 6 (11.8%). Mean follow-up was 36.12±25.15 months (range 0.5-90). There was no interim intervention or death. At follow-up, all the patients were in NYHA functional class 1 with no increase in severity of pulmonary insufficiency. CONCLUSION Supplementary bidirectional Glenn shunt significantly reduced residual right ventricular outflow obstruction during Tetralogy of Fallot repair avoiding revision with satisfactory early and mid-term results.

Abstract
BACKGROUND We reviewed our revised surgical strategy for tetralogy of Fallot (TOF) total correction to minimize early exposure to significant pulmonary regurgitation (PR) and to avoid right ventriculotomy (RV-tomy). Methods and Results: Since February 2016, we have tried to preserve, first, pulmonary valve (PV) function to minimize PR by extensive commissurotomy with annulus saving; and second, RV infundibular function by avoiding RV-tomy. With this strategy, we performed total correction for 50 consecutive patients with TOF until May 2018. We reviewed the early outcomes of 27 of 50 patients who received follow-up for ≥3 months. Mean patient age at operation was 10.2±5.0 months, and mean body weight was 8.8±1.2 kg. The preoperative pressure gradient at the RV outflow tract and the PV z-score were improved at most recent echocardiography from 82.0±7.1 to 26.8±6.4 mmHg, and from -2.35±0.49 to -0.55±0.54, respectively, during 11.1±1.6 months of follow-up after operation. One patient required re-intervention for residual pulmonary stenosis. Twenty-two patients had less than moderate PR (none, 1; trivial, 8; mild, 13), and 5 patients had moderate PR. There was no free or severe PR. CONCLUSIONS At 1-year follow-up, the patients who underwent total TOF correction with our revised surgical strategy had acceptable results in terms of PV function. The preserved PV had a tendency to grow on short-term follow-up.

Abstract
The prognosis of tetralogy of Fallot (TOF) treated only with Blalock-Taussig shunt (BTS) operation is unclear. A woman with TOF underwent classic BTS operation at 10 years of age. Despite no medication, she delivered two children and worked without apparent heart failure. At 72 years of age, she complained of dyspnea on exertion and leg edema. The cardiac angiogram revealed a well-patent BTS and severely stenotic right ventricular outflow tract. Right heart catheterization showed adequately maintained pulmonary blood flow with slight pulmonary arterial hypertension. Her unexpected yet favorable outcome reaffirms the importance of structural and functional self-adaptation even with cyanosis. If she had undergone a valve-sparing corrective surgery in adolescence, much better quality of life and outcome could have been expected.
