Abstract
BACKGROUND The aim of this study was to review our institution's experience with truncus arteriosus from prenatal diagnosis to clinical outcome. METHODS and results: We conducted a single-centre retrospective cohort study for the years 2005-2020. Truncus arteriosus antenatal echocardiographic diagnostic accuracy within our institution was 92.3%. After antenatal diagnosis, five parents (31%) decided to terminate the pregnancy. After inclusion from referring hospitals, 16 patients were offered surgery and were available for follow-up. Right ventricle-to-pulmonary artery continuity was preferably established without the use of a valve (direct connection), which was possible in 14 patients (88%). There was no early or late mortality. Reinterventions were performed in half of the patients at latest follow-up (median follow-up of 5.4 years). At a median age of 5.5 years, 13 out of 14 patients were still without right ventricle-to-pulmonary artery valve, which was well tolerated without signs of right heart failure. The right ventricle demonstrated preserved systolic function as expressed by tricuspid annular plane systolic excursion z-score (-1.4 ± 1.7) and fractional area change (44 ± 12%). The dimensions and function of the left ventricle were normal at latest follow-up (ejection fraction 64.4 ± 6.2%, fractional shortening 34.3 ± 4.3%). CONCLUSIONS This study demonstrates good prenatal diagnostic accuracy of truncus arteriosus. There was no mortality and favourable clinical outcomes at mid-term follow-up, with little interventions on the right ventricle-to-pulmonary artery connection and no right ventricle deterioration. This supports the notion that current perspectives of patients with truncus arteriosus are good, in contrast to the poor historic outcome series. This insight can be used in counselling and surgical decision-making.

A modified approach in the repair of type I and II truncus arteriosus to promote branch pulmonary arterial growth and limit early reoperation. JTCVS Tech 2022; 16:196-211. [PMID: 36510535 PMCID: PMC9735427 DOI: 10.1016/j.xjtc.2022.09.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 09/12/2022] [Accepted: 09/13/2022] [Indexed: 12/16/2022] Open
Abstract
Objective Maintaining adequate branch pulmonary arterial growth is critical in preventing early (<3 years) right ventricular outflow tract reoperation after the repair of truncus arteriosus. We hypothesized that a modified truncus arteriosus repair keeping the branch pulmonary arteries in situ would promote branch pulmonary arterial growth and limit early right ventricular outflow tract reoperation. Methods For infants requiring repair for type I and II truncus arteriosus, the truncal root was septated through a hockey stick incision keeping the branch pulmonary arteries in situ, the ventricular septal defect was closed, and a short aortic homograft was used to reconstruct the right ventricular outflow tract. Echocardiograms measured preoperative and follow-up branch pulmonary artery diameter. Results Between 1998 and 2020, 41 infants were repaired using the modified approach (type I, 28; type II, 13). With a median follow-up of 11.6 (interquartile range, 3.1-15.5) years, there was no significant change between preoperative left pulmonary artery and right pulmonary artery Z-scores and their corresponding follow-up measurement (left pulmonary artery: 0.97, interquartile range, 0.6-1.6 vs left pulmonary artery: 1.4, interquartile range, -0.3 to 1.9) (right pulmonary artery: 0.6, interquartile range, -0.4 to 1.7 vs right pulmonary artery: 0.3 interquartile range, 0.5-0.9). Only 7.3% (n = 2) of follow-up right pulmonary artery Z-scores were less than 2.5 Z-scores below preoperative measurements. Four children (9.8%) required early right ventricular outflow tract reoperation. On multivariable analysis, larger conduit Z-scores were associated with greater time to right ventricular outflow tract reoperation (hazard ratio, 0.55, confidence interval, 0.307-0.984; P = .043). Conclusions Maintaining the branch pulmonary arteries in situ at initial truncus arteriosus repair allows for branch pulmonary arterial growth, limiting early right ventricular outflow tract reoperation.

Abstract
OBJECTIVE We reviewed our center's experience with common arterial trunk. METHODS We included those with common arterial trunk in Nevada with estimated delivery dates or birth dates between June 2006 and May 2021. We excluded patients with functionally univentricular hearts. RESULTS We identified a total of 39: 32 prenatally and 7 postnatally. Of the 32 prenatally detected, 2 had elective termination, 2 had fetal demise, and 28 were live-born. Of the 7 postnatally diagnosed, 6 had prenatal care without a fetal echocardiogram, and 1 had no prenatal care. Overall, live-born prenatal detection was 28/34 (82%). Prenatal detection for 2006-2009 was 2/6 (33%) and for 2010-2021 was 26/28 (93%) p = .049. Of the 35 live-born infants, 1 died preoperatively, and 34 underwent neonatal surgery. Of the 34, 8 had palliation (birth weight 1.9±0.7 kg, range 0.8-2.6 kg), and 26 had a primary repair (birth weight 3.0±0.3 kg, range 2.6-4.0 kg) p = .0004. For all 34 neonatal surgical procedures, there were 2 (5.9%) deaths; however, there were no subsequent surgical or interventional catheterization mortalities. CONCLUSIONS In Nevada, current state-wide, general population prenatal detection of the common arterial trunk was more than 90%. By employing a combination of neonatal palliation and primary repair, surgical mortality was less than 6% in a cohort that included those with birth weights less than 2.5 kg, truncal valve surgery, and interrupted aortic arches.

Abstract
We studied conduit-related risk factors for mortality, conduit reintervention, conduit replacement, and pulmonary artery (PA) reinterventions after truncus repair. Patients who underwent truncus repair at our institution between 1995 and 2019 were studied. Cox proportional hazards modeling evaluated variables for association with mortality, time to conduit reintervention, time to conduit replacement, and time to PA reintervention. Truncus was repaired in 107 patients at median age of 17 days (IQR 9-45). Median follow-up time was 7 years. Aortic homografts were implanted in 57 (53%) patients, pulmonary homograft in 40 (37%), and bovine jugular conduit in 10 (9%). Median conduit size was 11 mm (IQR 10-12) and median conduit Z-score was 1.71 (IQR 1.08-2.34). At 5 years, there was 87% survival, 21% freedom from conduit reinterventions, 37% freedom from conduit replacements, and 55% freedom from PA reinterventions. Conduit size (HR 0.7, 95%CI 0.4-1.4, p=.41) and type (aortic homograft reference; bovine jugular vein graft HR 0.6, 95% CI 0.08-5.2, p=.69; pulmonary homograft HR 0.7, 95% CI 0.2-2.3, p=.58) were not associated with mortality. On multivariate analysis, the hazard for conduit reintervention, conduit replacement, and PA reintervention decreased with increasing conduit Z-score values of 1 to 2.5 (non-linear relationship, p<.01), with little additional reduction in hazard beyond this range. Implantation of a larger conduit within Z-score values of 1 and 2.5 is associated with a decreased hazard for conduit reintervention, conduit replacement, and PA reintervention after truncus repair. The type and size of the conduits did not impact mortality.

Abstract
Van Praagh (VP) A3 variant of truncus arteriosus (or common arterial trunk) is defined by only one pulmonary artery (usually the right) originating from the common trunk, while the other lung is supplied either by collaterals or a pulmonary artery arising from the aortic arch. This report describes a staged approach to manage a VP-A3 variant truncus arteriosus with ductal origin of the left pulmonary artery (LPA), a hypoplastic right pulmonary artery, and cyanosis. Initially, the ductal portion of the proximal LPA was stented with a Resolute Onyx drug-eluting stent. The pulmonary arteries grew and at four months of age had an acceptable McGoon ratio and Nakata index. The patient then underwent repair which included unifocalization of the branch pulmonary arteries, closure of the ventricular septal defect, and placement of a right ventricle-to-pulmonary artery homograft conduit.

Abstract
OBJECTIVES This study aimed to evaluate the outcomes and feasibility of different techniques of reconstruction of the right ventricular outflow tract (RVOT) in surgical repair of truncus arteriosus. METHODS We retrospectively reviewed all consecutive patients with truncus arteriosus who underwent successful surgical repair in our centre between 1994 and 2017. We analysed late results according to the type of RVOT repair. RESULTS We collected data from 29 survivors after truncus arteriosus repair. Six (20%) of them were affected by DiGeorge syndrome. The RVOT reconstruction was achieved using a valved conduit in 58.6%, while a direct right ventricle-pulmonary artery (RV-PA) anastomosis, with or without the interposition of the left atrial appendage, was performed in the remaining. At a median follow-up time of 7.9 years (interquartile range 1.8-13.1), 6 patients (3 affected by DiGeorge syndrome) died. Between the 2 groups, there were no differences in terms of the late mortality and onset of adverse events. However, the use of a conduit seemed more prone to reintervention and onset of adverse events. CONCLUSIONS Different RVOT reconstruction techniques are safe and have similar late outcomes. However, use of a direct RV-PA anastomosis and left atrial appendage interposition may reduce the need for reoperation in the long term.

Abstract
OBJECTIVES We compared the risk of mortality and reintervention after common arterial trunk (CAT) repair for different surgical techniques, in particular the reconstruction of the right ventricle outflow tract with left atrial appendage (LAA) without a monocusp. METHODS The study population comprised 125 patients with repaired CAT who were followed-up at our institution between 2000 and 2018. Statistical analysis included Cox proportional hazard models. RESULTS Median follow-up was 10.6 years. The 10-year survival rate was 88.2% (95% confidence interval [CI], 80.6-92.4) with the poorest outcome for CAT type IV (64.3%; 95% CI, 36.8-82.3; P < .01). In multivariable analysis, coronary anomalies (hazard ratio [HR], 11.63 [3.84-35.29], P < .001) and CAT with interrupted aortic arch (HR, 6.50 [2.10-20.16], P = .001) were substantial and independent risk factors for mortality. Initial repair with LAA was not associated with an increased risk of mortality (HR, 0.37 [0.11-1.24], P = .11). The median age at reintervention was 3.6 years [7.3 days-13.1 years]. At 10 years, freedom from reintervention was greater in the group with LAA repair compared with the valved conduit group, 73.3% (95% CI, 41.3-89.4) versus 17.2% (95% CI, 9.2-27.4) (P < .001), respectively. Using a valved conduit for repair (HR, 4.79 [2.45-9.39], P < .001), truncal valve insufficiency (HR, 2.92 [1.62-5.26], P < .001) and DiGeorge syndrome (HR, 2.01 [1.15-3.51], P = .01) were independent and clinically important risk factors for reintervention. CONCLUSIONS For the repair of CAT, the LAA technique for right ventricle outflow tract reconstruction was associated with comparable survival and greater freedom from reintervention than the use of a valved conduit.

Abstract
Background: Despite significant improvement in outcomes with truncus arteriosus (TA) repair, right ventricular outflow tract (RVOT) reconstruction with a right ventricular to pulmonary artery (RV-to-PA) conduit remains a source of long-term reintervention and reoperation. This study evaluated our experience with reintervention in homograft and polytetrafluoroethylene (PTFE) RV-to-PA conduits in neonates. Methods: Primary TA repairs from 2004 to 2016 at a single institution were included. Stratification was based on RVOT reconstruction with PTFE or homograft conduit. Primary outcome was operative conduit replacement. Secondary outcomes included the rates and types of catheter-based conduit interventions. Results: Twenty-eight patients underwent primary TA repair and 89.3% (n = 25) of them had RVOT reconstruction with a homograft (28.0%, n = 7) or PTFE (72.0%, n = 18) conduit. Rates of reoperation for conduit replacement and catheter-based interventions were similar between those with PTFE and homograft conduits (85.7% vs 72.2%, P = .49 and 57.1% vs 83.3%, P = .11, respectively). Additionally, the median time to conduit replacement and catheter-based conduit interventions were comparable. In multivariable analysis, conduit size, but not conduit type, was a predictor of conduit revision (hazard ratio: 1.66, 95% confidence interval: 1.11-2.49, P = .02). At five-year and ten-year follow-up, patients with PTFE conduits had better survival than those with homograft conduits (100.0% vs 71.4%, P = .02); however, no mortalities were associated with conduit reoperations or catheter-based reinterventions. Conclusions: Polytetrafluoroethylene and homograft RVOT reconstruction in neonatal TA repair demonstrate similar durability as defined by reoperation and reintervention rates. The validation of the durability of PTFE conduits in neonatal TA repair requires confirmatory studies in larger cohorts.

Abstract
BACKGROUND Multiple conduits for right ventricular outflow tract reconstruction exist, although the ideal conduit that maximizes outcomes remains controversial. We evaluated long-term outcomes and compared conduits for right ventricular outflow tract reconstruction in children with truncus arteriosus. METHODS Records of patients who underwent truncus arteriosus repair at our institution between 1981 and 2018 were retrospectively reviewed. Primary outcomes included survival and freedom from catheter reintervention or reoperation. Secondary analyses evaluated the effect of comorbidity, operation era, conduit type, and conduit size. RESULTS One hundred patients met inclusion criteria. Median follow-up time was 15.6 years (interquartile range, 5.3-22.2). Actuarial survival at 30 days, 5 years, 10 years, and 15 years was 85%, 72%, 72%, and 68%, respectively. Early mortality was associated with concomitant interrupted aortic arch (hazard ratio, 5.4; 95% confidence interval, 1.7-17.4; P = .005). Median time to surgical reoperation was 4.6 years (interquartile range, 2.9-6.8; n = 58). Right ventricle to pulmonary artery continuity was established with an aortic homograft (n = 14), pulmonary homograft (n = 41), or bovine jugular vein conduit (n = 36) in most cases. Multivariate analysis revealed longer freedom from reoperation with the bovine jugular vein conduit compared with the aortic homograft (hazard ratio, 3.1; 95% confidence interval, 1.3-7.7; P = .02) with no difference compared with the pulmonary homograft. Larger conduit size was associated with longer freedom from reoperation (hazard ratio, 0.7; 95% confidence interval, 0.6-0.9; P < .001). CONCLUSIONS The bovine jugular vein conduit is a favorable conduit for right ventricular outflow tract reconstruction in patients with truncus arteriosus. Concomitant interrupted aortic arch is a risk factor for early mortality.

Abstract
BACKGROUND Common arterial trunk (CAT) is a rare anomaly with a spectrum of pathology. We sought to identify current trends and factors associated with postnatal outcomes. METHODS This was a single-centre review including 153 live births with planned surgery. Patients were analyzed as 2 cohorts based on era of CAT diagnosis (1990 to 1999 vs 2000 to 2014) and complexity of disease (simple vs complex). "Complex" required the association with significant aortic arch obstruction, truncal valve (TV) stenosis/regurgitation, and/or branch pulmonary artery (PA) hypoplasia, respectively. RESULTS Sixteen (10%) died preoperatively, and this outcome was associated with significant TV stenosis (odds ratio [OR] 4.55; P = 0.01) and regurgitation (OR 3.17; P = 0.04); 130 (95%) of 137 operated infants underwent primary complete repair. Their survival rates to 1 year improved from 54% to 85% after 2000, although this outcome remained substantially lower for cases with a complex vs simple CAT repair (76% vs 95%; OR 6.46; P = 0.006). Other risk factors associated with decreased 1-year survival included diagnosis before 2000 (OR 4.48; P = 0.038) and a lower birth weight (OR 8.0 per kg weight; P = 0.001). Finally, of 93 survivors beyond year 1 of life, 76 (82%) had undergone a total of 224 reinterventions. Only 15 (16%) were alive without any surgical or catheter-based reintervention at study end. CONCLUSIONS Despite recent surgical improvements, postnatal mortality continues to be substantial if CAT is complicated by significant pathology of the TV, aortic arch, or branch PAs. Reoperations and catheter interventions are eventualities for most patients during childhood.

Which cardiovascular magnetic resonance planes and sequences provide accurate measurements of branch pulmonary artery size in children with right ventricular outflow tract obstruction? Int J Cardiovasc Imaging 2013; 30:329-38.

Abstract
Children with right ventricular outflow tract obstructive (RVOTO) lesions require precise quantification of pulmonary artery (PA) size for proper management of branch PA stenosis. We aimed to determine which cardiovascular magnetic resonance (CMR) sequences and planes correlated best with cardiac catheterization and surgical measurements of branch PA size. Fifty-five children with RVOTO lesions and biventricular circulation underwent CMR prior to; either cardiac catheterization (n = 30) or surgery (n = 25) within a 6 month time frame. CMR sequences included axial black blood, axial, coronal oblique and sagittal oblique cine balanced steady-state free precession (bSSFP), and contrast-enhanced magnetic resonance angiography (MRA) with multiplanar reformatting in axial, coronal oblique, sagittal oblique, and cross-sectional planes. Maximal branch PA and stenosis (if present) diameter were measured. Comparisons of PA size on CMR were made to reference methods: (1) catheterization measurements performed in the anteroposterior plane at maximal expansion, and (2) surgical measurement obtained from a maximal diameter sound which could pass through the lumen. The mean differences (Δ) and intra class correlation (ICC) were used to determine agreement between different modalities. CMR branch PA measurements were compared to the corresponding cardiac catheterization measurements in 30 children (7.6 ± 5.6 years). Reformatted MRA showed better agreement for branch PA measurement (ICC > 0.8) than black blood (ICC 0.4-0.6) and cine sequences (ICC 0.6-0.8). Coronal oblique MRA and maximal cross sectional MRA provided the best correlation of right PA (RPA) size with ICC of 0.9 (Δ -0.1 ± 2.1 mm and Δ 0.5 ± 2.1 mm). Maximal cross sectional MRA and sagittal oblique MRA provided the best correlate of left PA (LPA) size (Δ 0.1 ± 2.4 and Δ -0.7 ± 2.4 mm). For stenoses, the best correlations were from coronal oblique MRA of right pulmonary artery (RPA) (Δ -0.2 ± 0.8 mm, ICC 0.9) and sagittal oblique MRA of left pulmonary artery (LPA) (Δ 0.2 ± 1.1 mm, ICC 0.9). CMR PA measurements were compared to surgical measurements in 25 children (5.4 ± 4.8 years). All MRI sequences demonstrated good agreement (ICC > 0.8) with the best (ICC 0.9) from axial cine bSSFP for both RPA and LPA. Maximal cross sectional and angulated oblique reformatted MRA provide the best correlation to catheterization for measurement of branch PA's and stenosis diameter. This is likely due to similar angiographic methods based on reformatting techniques that transect the central axis of the arteries. Axial cine bSSFP CMR was the best surgically measured correlate of PA branch size due to this being a measure of stretched diameter. Knowledge of these differences provides more precise PA measurements and may aid catheter or surgical interventions for RVOTO lesions.

Abstract
We previously developed a cell-free, biodegradable scaffold for in-situ tissue-engineering vasculature (iTEV) in a canine inferior vena cava (IVC) model. In this study, we investigated application of this scaffold for iTEV of the pulmonary artery (iTEV-PA) in a canine model. In vivo experiments were conducted to determine scaffold characteristics and long-term efficacy. Biodegradable scaffolds comprised polyglycolide knitted fibers and an l-lactide and ε-caprolactone copolymer sponge, with an outer glycolide and ε-caprolactone copolymer monofilament reinforcement. Tubular scaffolds (8 mm diameter) were implanted into the left pulmonary artery of experimental animals (n = 7) and evaluated up to 12 months postoperatively. Angiography of iTEV-PA after 12 months showed a well-formed vasculature without marked stenosis, aneurysmal change or thrombosis of iTEV-PA. Histological analysis revealed a vessel-like vasculature without calcification. However, vascular smooth muscle cells were not well-developed 12 months post-implantation. Biochemical analyses showed no significant difference in hydroxyproline and elastin content compared with native PA. Our long-term results of cell-free tissue-engineering of PAs have revealed the acceptable qualities and characteristics of iTEV-PAs. The strategy of using this cell-free biodegradable scaffold to create relatively small PAs could be applicable in pediatric cardiovascular surgery requiring materials.

Abstract
Cardiac catheterisation continues to play an important role in the long-term management of patients with common arterial trunk and transposition of the great arteries. Although non-invasive imaging has largely eliminated the need for diagnostic catheterisation in newborns with these congenital cardiac lesions, cardiac catheterisation is an important tool for the diagnosis of a variety of problems encountered after surgical intervention, and allows interventions to be performed when feasible. We review the indications for cardiac catheterisation and describe the specifics for various interventional procedures for these patients in this manuscript.
