Abstract
BACKGROUND Anomalous aortic origin of a coronary artery (AAOCA) is associated with sudden death in the young. We sought to determine quality of life (QOL) in patients/families affected by AAOCA. METHODS Patients with AAOCA (8-18 years) were prospectively included from January 2016 to May 2017. Parent proxy and patient Pediatric Cardiac Quality of Life Inventory (PCQLI) were used to evaluate QOL and Pediatric Quality of Life Inventory (PedsQL) Family Impact Module to assess the impact of AAOCA on families, as primary outcomes. Secondary outcomes included peer relationship, anxiety, and depression assessed using patient-reported outcomes measurement information system. Patients deemed high-risk were offered surgery/exercise restriction. Generalized linear mixed regression models were used to determine significant predictors of outcomes. RESULTS Fifty-three patients, the majority (n = 31, 59%) unrepaired, and 49 caregivers were included. Using PCQLI, patient and parent proxy QOL scores were similar to published scores for children with long-QT syndrome. Patients' QOL score was associated with exertional symptoms, perceived chronic disease, and altered parent's concentration ability. Likewise, parent proxy QOL scores were associated with mother's living situation, exertional symptoms, parent missing work for ≥1 day, and disturbed parental functioning at work. Family impact scores were associated with lower maternal education, among other measures. Risk categories or surgical status did not impact patient, parent proxy reported, or family impact QOL. CONCLUSION Anomalous aortic origin of a coronary artery is associated with decreased QOL as perceived by patients and caregiver and is associated with numerous facets of family functioning. These findings are independent of risk categorization or surgical status.

Abstract
BACKGROUND There are limited published data focused on outcomes of transcatheter pulmonary valve replacement (TPVR) with either a Sapien XT or Sapien 3 (S3) valve. OBJECTIVES This study sought to report short-term outcomes in a large cohort of patients who underwent TPVR with either a Sapien XT or S3 valve. METHODS Data were entered retrospectively into a multicenter registry for patients who underwent attempted TPVR with a Sapien XT or S3 valve. Patient-related, procedural, and short-term outcomes data were characterized overall and according to type of right ventricular outflow tract (RVOT) anatomy. RESULTS Twenty-three centers enrolled a total of 774 patients: 397 (51%) with a native/patched RVOT; 183 (24%) with a conduit; and 194 (25%) with a bioprosthetic valve. The S3 was used in 78% of patients, and the XT was used in 22%, with most patients receiving a 29-mm (39%) or 26-mm (34%) valve. The implant was technically successful in 754 (97.4%) patients. Serious adverse events were reported in 67 patients (10%), with no difference between RVOT anatomy groups. Fourteen patients underwent urgent surgery. Nine patients had a second valve implanted. Among patients with available data, tricuspid valve injury was documented in 11 (1.7%), and 9 others (1.3%) had new moderate or severe regurgitation 2 grades higher than pre-implantation, for 20 (3.0%) total patients with tricuspid valve complications. Valve function at discharge was excellent in most patients, but 58 (8.5%) had moderate or greater pulmonary regurgitation or maximum Doppler gradients >40 mm Hg. During limited follow-up (n = 349; median: 12 months), 9 patients were diagnosed with endocarditis, and 17 additional patients underwent surgical valve replacement or valve-in-valve TPVR. CONCLUSIONS Acute outcomes after TPVR with balloon-expandable valves were generally excellent in all types of RVOT. Additional data and longer follow-up will be necessary to gain insight into these issues.

Abstract
Isolated pulmonary artery (PA) of ductal origin (IPADO) is a rare cardiac defect which requires surgical repair, with or without preceding palliation. We sought to determine the impact of treatment strategy on outcomes. Retrospective study of consecutive patients with IPADO that underwent staged or primary repair from 1/05 to 9/16 at 6 Congenital Cardiac Research Collaborative centers. Patients with single ventricle physiology, major aortopulmonary collaterals, or bilateral IPADO were excluded. Primary outcome was isolated PA z-score at late follow-up. Secondary outcomes included PA symmetry index (isolated:confluent PA diameter) and reintervention burden. Propensity score adjustment was used to account for baseline differences. Of 60 patients in the study cohort, 26 (43%) underwent staged and 34 (57%) primary repair. The staged and primary repair groups differed in weight at diagnosis and presence of other heart disease but not in baseline PA dimensions. Staged patients underwent ductal stent (n = 16) or surgical shunt (n = 10) placement followed by repair at 210 vs. 21 days in the primary repair group (p < 0.001). At median follow-up of 4.5 years post-repair, after adjustment, isolated PA z-score (- 0.74 [- 1.75, - 0.26] vs. - 1.95 [- 2.91, - 1.59], p = 0.012) and PA symmetry index (0.81 [0.49, 1.0] vs. 0.55 [0.48, 0.69], p = 0.042) significantly favored the staged repair group. Freedom from PA reintervention was not different between groups (adjusted HR 0.78 [0.41, 1.48]; p = 0.445). A staged approach to repair of IPADO is associated with superior isolated PA size and symmetry at late follow-up. Consideration should be given to initial palliation in IPADO patients, when feasible.

Abstract
Pulmonary vein stenosis is a rare and poorly understood condition causing obstruction of the large pulmonary veins and of blood flow from the lungs to the left atrium. This results in elevated pulmonary venous pressure and pulmonary edema, pulmonary hypertension, potentially cardiac failure, and death. Clinical signs of the disease include failure to thrive, increasingly severe dyspnea, hemoptysis, respiratory difficulty, recurrent respiratory tract infections/pneumonia, cyanosis, and subcostal retractions. On chest radiograph, the most frequent finding is increased interstitial, ground-glass and/or reticular opacity. Transthoracic echocardiography with pulsed Doppler delineates the stenosis, magnetic resonance imaging and multislice computerized tomography are used for further evaluation. Interventional cardiac catherization, surgical techniques, and medical therapies have been used with varying success as treatment options.

Abstract
INTRODUCTION The optimal management of scimitar syndrome remains incompletely defined. We (1) evaluated the impact of aortopulmonary collateral (APC) occlusion, (2) compared outcomes according to surgical approach for patients who underwent surgery, and (3) identified anatomic factors associated with longer survival time without scimitar vein repair. METHODS We conducted a single center, retrospective study of 61 patients diagnosed with scimitar syndrome between 1995 and 2019. Right pulmonary artery to total pulmonary artery cross-sectional area (RPA:PA CSA) quantitatively assessed right pulmonary artery size. Anatomical features were analyzed for association with longer survival time without scimitar vein repair. RESULTS Median follow-up time was 6 years (Q1-Q3, 2-12), with 96% 5-year survival. Twenty-three patients underwent APC occlusion, which significantly decreased symptoms of overcirculation (100%-46%; p = .001) and systolic pulmonary artery pressure (median, 34-29 mmHg; p = .004). Twenty-three patients underwent scimitar vein repair; 5-year freedom from scimitar vein stenosis was 90% among patients who underwent a reimplantation compared with 42% in patients with baffle repair (p = .1). Three patients underwent surgery before the first year of age, with lower 5-year freedom from scimitar vein stenosis (0% vs. 84%; p < .001). On multivariate analysis, a lower RPA:PA CSA was associated with longer survival time without scimitar vein repair (p = .003). CONCLUSIONS APC occlusion improves the clinical status of young and hemodynamically unstable patients. Repair at an early age is associated with an increased risk of scimitar vein stenosis. Scimitar vein repair might be avoided in patients with a smaller right pulmonary artery.

Abstract
Anomalous aortic origin of a left coronary artery (L-AAOCA) with an intraseptal course is a rare anomaly and can be associated with myocardial ischemia and sudden cardiac death. No surgical or medical intervention is known to improve patient outcomes. A 7-year-old boy with intraseptal L-AAOCA presented with nonexertional chest pain, syncope, and had reversible myocardial ischemia on provocative testing. The patient was started on β-blockade, following which his symptoms improved and resolved over a period of six years. A follow-up dobutamine stress magnetic resonance imaging no longer showed reversible ischemia, and cardiac catheterization with fractional flow reserve did not show coronary flow compromise.

Abstract
OBJECTIVE To compare management strategies for neonates <2.5 kg with tetralogy of Fallot and symptomatic cyanosis who either undergo staged repair (SR) (initial palliation followed by later complete repair) or primary repair (PR). METHODS Consecutive neonates with tetralogy of Fallot and symptomatic cyanosis weighing <2.5 kg at initial intervention and between 2005 and 2017 were retrospectively reviewed from the Congenital Cardiac Research Collaborative. Primary outcome was mortality and secondary outcomes included component (eg, initial palliation, complete repair, or primary repair) and cumulative (SR: initial palliation followed by later complete repair) hospital and intensive care unit lengths of stay, durations of ventilation, inotrope use, cardiopulmonary bypass time, procedural complications, and reintervention. Outcomes were compared with propensity score adjustments with PR as the reference group. RESULTS The cohort included 76 SR (initial palliation: 53 surgical and 23 transcatheter) and 44 PR patients. The observed risk of overall mortality was similar between SR and PR groups (15.8% vs 18.2%: P = .735). The adjusted hazard of mortality remained similar between groups overall (hazard ratio, 0.59; 95% confidence interval, 0.26-1.36; P = .214), as well as during short-term (<4 months: hazard ratio, 0.37; 95% confidence interval, 0.13-1.09; P = .071) and midterm (>4 months: hazard ratio, 1.32; 95% confidence interval, 0.30-5.79; P = .717) follow-up. Reintervention in the first 18 months was common in both groups (53.2% vs 48.4%; hazard ratio, 1.69; 95% confidence interval, 0.96-2.28; P = .072). Adjusted procedural complications and neonatal morbidity burden were overall lower in the SR group. Cumulative secondary outcome burdens largely favored the PR group. CONCLUSIONS In this study comparing SR and PR treatment strategies for neonates with tetralogy of Fallot and symptomatic cyanosis and weight <2.5 kg, mortality and reintervention burden was highly independent of treatment strategy. Other potential advantages were observed with each approach.

Abstract
BACKGROUND Invasive fractional flow reserve (FFR) is considered the gold standard to evaluate coronary artery flow. Stress cardiovascular magnetic resonance (sCMR) is an emerging non-invasive tool to evaluate myocardial perfusion in children. We sought to compare sCMR with FFR to determine impaired intracoronary flow in children with anomalous aortic origin of a coronary artery (AAOCA) and/or myocardial bridge (MB) who presented concern for myocardial ischemia. METHODS From December 2012 to May 2019, AAOCA and/or MB patients (<20 years old) were prospectively enrolled and underwent sCMR and FFR. Abnormal sCMR included perfusion/regional wall-motion abnormality in the involved coronary distribution. FFR was performed at baseline and with dobutamine/regadenoson and considered abnormal if <0.8 in the affected coronary segment. RESULTS Of 376 patients evaluated, a total of 19 (age range, 0.2-17 years) underwent 24 sets of sCMR and FFR studies, with 5 repeat studies following intervention. Types of anomalies included 6 isolated MB/normal CA origins, 5 single CAs, 5 left AAOCAs, and 3 right AAOCAs. Seventeen patients (89.5%) had MB/intramyocardial course - 14 involving the left anterior descending coronary artery and 3 with multivessel involvement. sCMR correlated with FFR in 19/24 sets (7 sCMR and FFR positive, 12 sCMR and FFR negative) and it did not correlate in 5/24 sets. The positive percent agreement was 77.8%, negative percent agreement was 80.0%, and overall percent agreement was 79.2%. CONCLUSIONS Assessment of myocardial perfusion using non-invasive sCMR concurred with FFR, particularly if performed with close proximity in time, and may contribute to risk stratification and decision making in children with AAOCA and/or MB.

Abstract
BACKGROUND Multiple techniques are available for repair of supracardiac partial anomalous pulmonary venous return (PAPVR); however, most series fail to compare the techniques in contemporary cohorts. This study aimed to describe outcomes of the Warden procedure with a single-patch repair cohort to serve as a control. METHODS A retrospective cohort analysis of all patients at a single institution (Texas Children's Hospital, Houston, TX) included patients undergoing either the Warden procedure or single-patch repair from 1996 to 2019 for PAPVR. Reintervention was defined as any catheter or surgical procedure on the superior vena cava (SVC) or pulmonary veins. Subgroup analysis was performed within the Warden cohort to evaluate for association between an SVC patch and reintervention-free survival. RESULTS In total, 158 patients (122 in the Warden group and 36 in the single-patch group) were identified. The median age at operation was younger for patients in the Warden cohort (5.4 years; interquartile range, 3.3 to 10.2 years) compared with patients in the single-patch cohort (13.3 years; interquartile range, 6.5 to 18.7 years; P < .001). One patient in each cohort died. One patient required reoperation after the Warden procedure for dehiscence of the intracardiac patch. Ten patients required transcatheter reinterventions. Reintervention-free survival was not different between patients in the Warden cohort and patients in the single-patch cohort (P = .54) or within the Warden cohort in patients with an SVC patch (P = .27). When controlling for repair type, older age at repair was associated with longer reintervention-free survival (hazard ratio, 0.81; 95% confidence interval, 0.71 to 0.93; P = .002). CONCLUSIONS The Warden procedure is a viable option for younger patients requiring supracardiac PAPVR repair, although these younger patients are likely at greatest risk for reintervention regardless of surgical technique.

Abstract
Epic Supra valves have been used off-label in the pulmonary position. We aim to evaluate the durability of Epic valves in the pulmonary position. We performed a retrospective review of all Epic valves placed in the pulmonary position from October 2008 to May 2019. Time-to-event analysis was performed using Kaplan-Meier estimates to evaluate freedom from valve intervention, moderate pulmonary regurgitation, and peak velocity greater than 3.5 m/s. Valve dysfunction was a composite of all 3 end points. A total of 79 patients had Epic valves implanted in the pulmonary position. Median age was 18.5 years (15th-85th percentile 11.2-41.0). In total, 1 (1%) 19 mm valve, 4 (5%) 21 mm valves, 8 (10%) 23 mm valves, 23 (29%) 25 mm valves, and 43 (54%) 27 mm valves were implanted. There were no deaths or transplants. Median follow-up was 3.1 years (interquartile range 1.0-5.5). At 5 years, freedom from valve intervention was 95%, freedom from valve dysfunction was 68%, freedom from moderate pulmonary regurgitation was 73%, and freedom from peak velocity greater than 3.5 m/s was 82%. Epic Supra valves provide an acceptable valve replacement in the pulmonary position for children and adults. Longer follow-up is needed to determine valve durability through the entirety of the valve life expectancy.

Abstract
BACKGROUND The novel coronavirus (COVID-19) pandemic has placed severe stress on healthcare systems around the world. There is limited information on current practices in pediatric cardiac catheterization laboratories in the United States (US). OBJECTIVES To describe current practice patterns and make recommendations regarding potential resource allocation for congenital cardiac catheterization during the COVID-19 pandemic. METHODS A web-based survey was distributed regarding case candidacy and catheterization laboratory preparedness. Centers were categorized based on the current degree of disease burden in that community (as of April 1, 2020). Data and consensus opinion were utilized to develop recommendations. RESULTS Respondents belonged to 56 unique US centers, with 27 (48.2%) located in counties with a high number of COVID-19 cases. All centers have canceled elective procedures. There was relative uniformity (>88% agreement) among centers as to which procedures were considered elective. To date, only three centers have performed a catheterization on a confirmed COVID-19 positive patient. Centers located in areas with a higher number of COVID-9 cases have been more involved in a simulation of donning and doffing personal protective equipment (PPE) than low-prevalence centers (46.7% vs 10.3%, respectively; P<.001). Currently, only a small fraction of operators has been reassigned to provide clinical services outside their scope of practice. CONCLUSIONS At this stage in the COVID-19 pandemic, pediatric/congenital catheterization laboratories have dramatically reduced case volumes. This document serves to define current patterns and provides guidance and recommendations on the preservation and repurposing of resources to help pediatric cardiac programs develop strategies for patient care during this unprecedented crisis.

Abstract
OBJECTIVES Instantaneous wave-free ratio (iFR) has been proven to correlate with coronary flow reserve better than fractional flow reserve (FFR) and is non-inferior to FFR in guiding coronary revascularization in ischemic heart disease. There has been no study validating the utility of iFR in children. METHODS We performed a retrospective review of clinically indicated cases in which both FFR and iFR were obtained at Texas Children's Hospital from July, 2016 to March, 2019. FFR and iFR were obtained at baseline. Adenosine FFR (FFRa) was used for assessment of coronary artery (CA) stenoses and diastolic dobutamine FFR (dFFRd) for myocardial bridges (MBs). FFRa or dFFRd ≤0.8 and iFR ≤0.89 indicated significant flow impairment. RESULTS A total of 22 coronary arteries (9 CA stenoses and 13 MBs) were assessed in 20 patients with median age of 13 years (range, 4-21 years) and median weight of 60 kg (range, 19-110 kg). iFR correlated with FFRa (Spearman's rho, 0.87; P<.01) in CA stenoses and with dFFRd (Spearman's rho, 0.74; P<.01) in MBs and agreed with FFR in 20/22 cases (90.9%). In 1 patient with CA stenosis and 1 MB with normal FFR, iFR was positive and both patients underwent coronary revascularization. CONCLUSIONS iFR correlated with FFR in the assessment of CA stenoses in children. iFR does not require administration of pharmacological agents; thus, it may reduce procedural time, cost, and complications, and result in more widespread adoption of invasive assessment of CA lesions in young patients.

Abstract
Introduction: Pulmonary atresia with the ventricular septal defect is a rare congenital heart defect with high anatomic variability. The most important management question relates to the sources of pulmonary blood flow. The ability to differentiate between ductal dependence and major aortopulmonary collateral arteries is critical to achieving good outcomes and avoiding life-threatening hypoxia in the postneonatal period. Having accurate information about pulmonary arteries, major aortopulmonary collateral arteries, and sources of blood supply to each pulmonary segment is crucial for choosing the optimal surgical strategy. The purpose of this study is to compare computed tomography angiography (CTA) with cardiac catheterization for anatomic delineation of surgically relevant anatomy in pulmonary atresia with ventricular septal defect with major aortopulmonary collateral arteries. Materials and Methods: Retrospective review of all children with pulmonary atresia with ventricular septal defect with major aortopulmonary collateral arteries cared for at a large tertiary children's hospital who underwent cardiac catheterization with angiography and CTA close to each other without interval therapy. All studies were performed between 2007 and 2011. Results: There were 9 patients who met the inclusion criteria. Pulmonary artery anatomy (confluent vs. nonconfluent) was correctly identified in 9 patients by CTA and 8 patients by catheterization. There were no significant differences between CTA and catheterization in the identification of major aortopulmonary collateral arteries (mean = 3.4 collaterals/study via catheterization; mean = 3.1 collaterals/study via CTA; P = 0.67). CTA was superior to catheterization in the delineation of segmental pulmonary blood flow (P = 0.006). Conclusion: CTA and catheterization are equivalent in their ability to delineate pulmonary artery anatomy and major aortopulmonary collateral arteries.

Abstract
Iatrogenic aortopulmonary communications (IAPCs) are an uncommon but important complication after percutaneous intervention in postoperative patients. Iatrogenic aortopulmonary communications typically occur after balloon angioplasty or other interventions of the pulmonary outflow tract in certain anatomic configurations in which there is a denuded tissue plane between the pulmonary artery and aorta. They can present with signs and symptoms ranging from subtle clues which are difficult to recognize to near immediate hemodynamic instability. Once recognized, these lesions can become management dilemmas, and intraprocedural interventions can be complicated by complex anatomy and inadequate visualization by standard imaging techniques. We report cases where intracardiac echocardiography (ICE) was integral in the evaluation and management of IAPC as complications of prior transcatheter interventions. We found using ICE safely and effectively identified IAPCs and reduced the technical difficulty of intervention after IAPC discovery.

Abstract
Background:
Intraseptal anomalous aortic origin of a coronary artery is considered a benign condition. However, there have been case reports of patients with myocardial ischemia, arrhythmia, and sudden cardiac death. The purpose of this study was to determine the clinical presentation, myocardial perfusion on provocative stress testing, and management of children with anomalous aortic origin of a coronary artery with an intraseptal course in a prospective cohort.
Methods:
Patients with anomalous aortic origin of a coronary artery and intraseptal course were prospectively enrolled from December 2012 to May 2019, evaluated, and managed following a standardized algorithm. Myocardial perfusion was assessed using stress imaging. Fractional flow reserve was performed in patients with myocardial hypoperfusion on noninvasive testing. Exercise restriction, β-blockers, and surgical intervention were discussed with the families.
Results:
Eighteen patients (female 6, 33.3%), who presented with no symptoms (10, 55.6%), nonexertional (4, 22.2%), and exertional symptoms (4, 22.2%), were enrolled at a median age of 12.4 years (0.3–15.9). Perfusion imaging was performed in 14/18 (77.8%) and was abnormal in 7/14 (50%); fractional flow reserve was positive in 5/8 (62.5%). All 4 patients with exertional symptoms and 3/10 (30%) with no or nonexertional symptoms had myocardial hypoperfusion. Coronary artery bypass grafting was performed in a 4-year-old patient; β-blocker and exercise restriction were recommended in 4 patients not suitable for surgery. One patient had nonexertional chest pain and 17 were symptom-free at median follow-up of 2.5 years (0.2–7.1).
Conclusions:
Up to 50% of patients with intraseptal anomalous aortic origin of a coronary artery had inducible myocardial hypoperfusion during noninvasive provocative testing. Long-term follow-up is necessary to understand the natural history of this rare anomaly.

Abstract
Background: Atrial septal defect and Impella have been proposed for left ventricular unloading in venoarterial extracorporeal membrane oxygenation patients. This work aims at evaluating the haemodynamic changes in venoarterial extracorporeal membrane oxygenation patients after Impella implantation or atrial septal defect realization by a simulation study. Methods: A lumped parameter model of the cardiovascular system was adapted to this study. Atrial septal defect was modelled as a resistance between the two atria. Venoarterial extracorporeal membrane oxygenation and Impella were modelled starting from their pressure-flow characteristics. The baseline condition of a patient undergoing venoarterial extracorporeal membrane oxygenation was reproduced starting from haemodynamic and echocardiographic data. The effects of different atrial septal defect size, Impella and venoarterial extracorporeal membrane oxygenation support were simulated. Results: Impella caused an increment of mean arterial pressure up to 67%, a decrement in mean pulmonary arterial pressure up to 8%, a decrement in left ventricular end systolic volume up to 11% with a reduction up to 97% of left ventricular cardiac output. Atrial septal defect reduces left atrial pressure (19%), increases right atrial pressure (22%), increases mean arterial pressure (18%), decreases left ventricular end systolic volume (11%), increases right ventricular volume (33%) and decreases left ventricular cardiac output (55%). Conclusion: Impella has a higher capability in left ventricular unloading during venoarterial extracorporeal membrane oxygenation in comparison to atrial septal defect with a lower right ventricular overload.

Abstract
Unilateral proximal pulmonary artery stenosis is often seen in the setting of postoperative congenital heart disease. Accurate assessment of the hemodynamic significance of such a lesion is important so as to determine "When to intervene?" A thorough evaluation should include symptom assessment, anatomical assessment through detailed imaging, functional assessment using differential pulmonary blood flow measurement and cardiopulmonary exercise testing. Symptoms of exertional dyspnea or intolerance, decreased pulmonary blood flow to stenosed lung, and abnormal exertional performance would be factors to pursue therapy in the setting of significant anatomical narrowing. Safe and effective therapy can be offered through transcatheter or surgical techniques and has been shown to improve exertional performance.

Abstract
Background:
Anomalous aortic origin of a coronary artery (CA) is the second leading cause of sudden cardiac death in young athletes. Management is controversial and longitudinal follow-up data are sparse. We aim to evaluate outcomes in a prospective study of anomalous aortic origin of CA patients following a standardized algorithm.
Methods:
Patients with anomalous aortic origin of a CA were followed prospectively from December 2012 to April 2017. All patients were evaluated following a standardized algorithm, and data were reviewed by a dedicated multidisciplinary team. Assessment of myocardial perfusion was performed using stress imaging. High-risk patients (high-risk anatomy—anomalous left CA from the opposite sinus, presence of intramurality, abnormal ostium—and symptoms or evidence of myocardial ischemia) were offered surgery or exercise restriction (if deemed high risk for surgical intervention). Univariate and multivariable analyses were used to determine predictors of high risk.
Results:
Of 201 patients evaluated, 163 met inclusion criteria: 116 anomalous right CA (71%), 25 anomalous left CA (15%), 17 single CA (10%), and 5 anomalous circumflex CA (3%). Patients presented as an incidental finding (n=80, 49%), with exertional (n=31, 21%) and nonexertional (n=32, 20%) symptoms and following sudden cardiac arrest/shock (n=5, 3%). Eighty-two patients (50.3%) were considered high risk. Predictors of high risk were older age at diagnosis, black race, intramural course, and exertional syncope. Most patients (82%) are allowed unrestrictive sports activities. Forty-seven patients had surgery (11 anomalous left CA and 36 anomalous right CA), 3 (6.4%) remained restricted from sports activities. All patients are alive at a median follow-up of 1.6 (interquartile range, 0.7–2.8) years.
Conclusions:
In this prospective cohort of patients with anomalous aortic origin of a CA, most have remained free of exercise restrictions. Development of a multidisciplinary team has allowed a consistent approach and may have implications in risk stratification and long-term prognosis.

Abstract
Background In infants with ductal‐dependent pulmonary blood flow, the impact of palliation strategy on interstage growth and feeding regimen is unknown. Methods and Results This was a retrospective multicenter study of infants with ductal‐dependent pulmonary blood flow palliated with patent ductus arteriosus (PDA) stent or Blalock‐Taussig shunt (BTS) from 2008 to 2015. Subjects with a defined interstage, the time between initial palliation and subsequent palliation or repair, were included. Primary outcome was change in weight‐for‐age Z‐score. Secondary outcomes included % of patients on: all oral feeds, feeding‐related medications, higher calorie feeds, and feeding‐related readmission. Propensity score was used to account for baseline differences. Subgroup analysis was performed in 1‐ (1V) and 2‐ventricle (2V) groups. The cohort included 66 PDA stent (43.9% 1V) and 195 BTS (54.4% 1V) subjects. Prematurity was more common in the PDA stent group (P=0.051). After adjustment, change in weight‐for‐age Z‐score did not differ between groups over the entire interstage. However, change in weight‐for‐age Z‐score favored PDA stent during the inpatient interstage (P=0.005) and BTS during the outpatient interstage (P=0.032). At initial hospital discharge, PDA stent treatment was associated with all oral feeds (P<0.001) and absence of feeding‐related medications (P=0.002). Subgroup analysis revealed that 2V but not 1V patients demonstrated significant increase in weight‐for‐age Z‐score. In the 2V cohort, feeding‐related readmissions were more common in the BTS group (P=0.008). Conclusions In infants with ductal‐dependent pulmonary blood flow who underwent palliation with PDA stent or BTS, there was no difference in interstage growth. PDA stent was associated with a simpler feeding regimen and fewer feeding‐related readmissions.

Abstract
OBJECTIVE Predictors of right ventricle (RV) dysfunction after continuous-flow left ventricular assist device (CF-LVAD) implantation in children are not well described. We explored the association of preimplantation Pulmonary Artery Pulsatility index (PAPi) and other hemodynamic parameters as predictors of prolonged postoperative inotropes/pulmonary vasodilator use after CF-LVAD implantation. DESIGN Retrospective chart review. SETTING Single tertiary care pediatric referral center. PATIENTS Patients who underwent CF-LVAD implantation from January 2012 to October 2017. INTERVENTIONS Preimplantation invasive hemodynamic parameters were analyzed to evaluate the association with post-CF-LVAD need for prolonged (>72 hours) use of inotropes/pulmonary vasodilators. MEASUREMENTS AND MAIN RESULTS Preimplantation cardiac catheterization data was available for 12 of 44 patients who underwent CF-LVAD implant during the study period. Median (IQR) age and BSA of the cohort were 15.3 years (10.2, 18) and 1.74 m2 (0.98, 2.03). Group 1 (n = 6) included patients with need for prolonged inotropes/pulmonary vasodilator use after CF-LVAD implantation and Group 2 (n = 6) included those without. Baseline demographic parameters, cardiopulmonary bypass time, and markers of RV afterload (pulmonary vascular resistance, PA compliance and elastance) were similar among the two groups. PAPi was significantly lower in group 1 compared to group 2 (0.96 vs 3.6, respectively; P = .004). Post-LVAD stay in the intensive care unit was longer for patients in group 1 (46 vs 23 days, P = .52). Brain natriuretic peptide was significantly higher at 3 months after implantation in group 1; P = .01. CONCLUSIONS The need for inotropes/pulmonary vasodilators in the postoperative period can be predicted by the preimplantation intrinsic RV contractile reserve as assessed by PAPi rather than the markers of RV afterload. Further investigation and correlation with clinical outcomes is needed.

Abstract
Pulmonary hypertension (PH), defined as mean pulmonary arterial pressure ≥25 mm Hg, may be a complication of a secundum atrial septal defect (ASD). This study sought to evaluate the impact of PH at time of ASD device closure on patient survival. A prospectively collected database of ASD closures was utilized. Patients were stratified by age above and below the cohort median (48 years). Survival was analyzed by preprocedural PH status, age cohort, and echocardiographic resolution of PH at 3 months postdevice closure. PH was present in 48 of 228 patients (21.1%) and was more common in the older cohort (31.3% vs 10.6%, p <0.01). ASD size was unrelated to the presence of PH (p = 0.33). Older patients had more medical co-morbidities including diabetes (p = 0.02), hyperlipidemia (p <0.01), and systemic hypertension (p <0.01) compared with younger patients. PH did not impact survival in patients ≤48 years, but PH was associated with fivefold increased risk of death in patients >48 years (p < 0.01). Patients with preprocedural PH and RVSP ≥40 mm Hg at 3-month follow-up continued to have an increased risk of mortality (p <0.01), whereas those with resolution of PH had similar survival to those without PH at time of closure. In conclusion, PH is common in adults with unrepaired ASDs and appears unrelated to defect size. PH in older adults and its persistence closure are strong predictors of a worsened clinical outcome. These patients may benefit from additional risk assessment and advanced medical therapies to mitigate this risk.

Abstract
BACKGROUND Patients with single ventricle anatomy and ductal-dependent pulmonary blood flow may be initially palliated with either modified Blalock-Taussig shunt (BTS) or ductus arteriosus stent (DAS). Comparisons of outcomes during the interstage period and at the time of superior cavopulmonary connection (SCPC) are lacking and may differ between palliation strategies. METHODS Infants with single ventricle anatomy and ductal-dependent pulmonary blood flow palliated with either DAS or BTS from 2008 to 2015 were reviewed across 4 centers. Interstage outcomes, and for those who had SCPC, anatomy, hemodynamics, and perioperative clinical outcomes were compared. Thirty-five patients with DAS and 136 patients with BTS were included. RESULTS At initial palliation, demographic, clinical variables, and pulmonary artery size were similar. Interstage death, transplant, or unplanned reintervention to treat cyanosis occurred in 25.7% of DAS and 35.8% of BTS, P=0.27. Reintervention was more common with DAS (48.6% versus 2.2%; P<0.001). Twenty-three DAS patients and 111 BTS patients underwent SCPC. Preoperative hemodynamics and overall pulmonary atresia growth were similar, although right pulmonary artery growth was better with DAS (change in z-score: 1.57 versus 0.65, P=0.026). SCPC intraoperative and postoperative courses were similar. CONCLUSIONS In patients with single-ventricle anatomy and ductal-dependent pulmonary blood flow, interstage outcomes, hemodynamics before SCPC, and acute postoperative outcomes were similar. Overall reintervention was more common in the DAS group, driven by more frequent planned reintervention. Unplanned reintervention, death, and transplant were similar. Both groups demonstrated good pulmonary atresia growth. DAS is a reasonable initial palliative alternative to BTS in select patients.

Abstract
Children with homozygous familial hypercholesterolemia are at risk for early cardiovascular events secondary to coronary artery disease. Current medical therapy does not ameliorate this risk. Liver transplantation offers the most effective option to reduce circulating levels of low-density lipoprotein cholesterol and thereby reduce risk of cardiovascular events. Angiographic evidence of regression of coronary artery disease is presented.

Am J Cardiol 2019; 124:952-959. [PMID: 31350000 DOI: 10.1016/j.amjcard.2019.06.014] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Revised: 06/05/2019] [Accepted: 06/10/2019] [Indexed: 12/20/2022]
Abstract
There have been no clinical studies evaluating the use of drug-eluting stents (DES) versus bare metal stents (BMS) for infants who underwent ductus arteriosus (DA) stent placement for ductal-dependent pulmonary blood flow (PBF). We aimed to compare the use of second-generation (fluoropolymer-coated everolimus) DES to BMS in infants who underwent DA stenting for ductal-dependent PBF. A retrospective study of infants who underwent DA stenting for ductal-dependent PBF from January 2004 to March 2018 at a single tertiary care pediatric hospital was performed. Of 94 infants identified, 71 (46 BMS and 25 DES) met inclusion criteria. Baseline characteristics of the DES and BMS cohorts were comparable. The patent lumen to stent diameter on subsequent angiographic evaluation was 81% in DES as compared with 50% in BMS group; p = 0.01. There were 2 deaths early in our experience, both in the BMS group. Unplanned reinterventions were less in the DES group (3, 12% patients) compared with the BMS group (13, 28%), p = 0.03. Pulmonary artery size as assessed using Nakata and pulmonary artery symmetry index was comparable in both the groups. There was no difference in infection rates between the groups. On multivariate analysis, prematurity, BMS, and lower oxygen saturations at discharge were associated with subsequent unplanned reintervention (p = 0.01, 0.03 and 0.03, respectively). In conclusion, our clinical experience suggests that in infants who underwent DA stenting for ductal-dependent PBF, (fluoropolymer-coated everolimus eluting) DES results in less luminal loss and lower unplanned reintervention for cyanosis as compared with BMS implantation.

Abstract
BACKGROUND Percutaneous transcatheter pulmonary valve replacement (TPVR) has good clinical and hemodynamic outcomes in treating dysfunctional bioprosthetic valves (BPV) in the pulmonary position. Valve-in-valve therapy can further decrease the inner diameter (ID), potentially resulting in patient-prosthesis mismatch in patients with smaller BPVs. METHODS AND RESULTS To evaluate feasibility and outcomes of intentional BPV fracture to enlarge the pulmonary valve orifice with TPVR, 37 patients from 13 centers who underwent TPVR with intended BPV fracture were evaluated. A control cohort (n=70) who underwent valve-in-valve TPVR without attempted fracture was evaluated. BPV was successfully fractured in 28 patients and stretched in 5 while fracture was unsuccessful in 4. A Melody valve was implanted in 25 patients with fractured/stretched frame and a Sapien (XT 3) valve in 8. Among patients whose BPV was fractured/stretched, the final ID was a median of 2 mm larger (0-6.5 mm) than the valve's true ID. The narrowest diameter after TPVR in controls was a median of 2 mm smaller ( P<0.001) than true ID. Right ventricular outflow tract gradient decreased from median 40 to 8 mm Hg in the fracture group. Cases with fracture/stretching were matched 1:1 (weight, true ID) to controls. Post-TPVR peak gradient was lower but not significant (8.3±5.2 versus 11.8±9.2 mm Hg; P=0.070). There were no fracture-related adverse events. CONCLUSIONS Preliminary experience shows intentional fracture of BPV frame can be useful for achieving larger ID and better hemodynamics after valve-in-valve TPVR.

Abstract
We present a case of temporary guidewire pacing in a patient with Fontan anatomy during transcatheter aortic valve implantation. Temporary pacing was successfully achieved utilizing this method without complications. There is an increasing population of patients with complex congenital heart disease and expanding variety of transcatheter interventions. Due to limitations in vascular access and surgical anatomies, guidewire pacing may have a wide array of potential applications in pediatrics and the congenital heart disease population.

Abstract
The use of prostaglandin-E1 immediately after birth and subsequent surgical creation of the modified Blalock-Taussig shunt (BTS) shunt have remarkably improved the prognosis and survival of children with congenital heart disease and ductal-dependent pulmonary blood flow (PBF). Despite the advancement in surgical techniques, bypass strategies, and postoperative management, significant morbidity and mortality after BTS still remain. Patent ductus arteriosus stenting has been shown to be as an acceptable alternative to BTS placement in select infants with ductal-dependent PBF. Newer procedural techniques and equipment, along with operator experience have all contributed to procedural refinement associated with improved outcomes over the recent years. In this article, we review the procedural and periprocedural details, with an emphasis on recent advances of this procedure.

Abstract
BACKGROUND Infants with ductal-dependent pulmonary blood flow (PBF) often undergo a palliative procedure to provide a stable source of PBF prior to definitive palliation or repair. In the current era, a surgical shunt or ductal stent is used to provide PBF. We aimed to review the current literature comparing ductal stents to surgical shunts. METHODS AND RESULTS Four small, single-center studies and two larger multicenter studies were identified comparing ductal stent to surgical shunt. Combined, these studies showed ductal stent resulted in similar or improved pulmonary artery growth, fewer complications, shorter length of stay, less diuretic use, and improved survival compared to surgical shunt. Despite inherent minor variability among the studies, ductal stent appears to be associated with more frequent reinterventions. CONCLUSIONS Surgical shunts remain essential to the care of these patients, but ductal stent is a reasonable alternative, and may provide some advantages in select patients with ductal-dependent PBF.

Abstract
BACKGROUND Patent ductus arteriosus (PDA) is highly prevalent in extremely low birth weight (ELBW), preterm infants. There are diverse management approaches for the PDA in ELBW infants. The objectives of this research were to identify current PDA management practices among cardiologists and neonatologists in the United States, describe any significant differences in management, and describe areas where practices align. METHODS A survey of 10 questions based on the management of PDA in ELBW infants was conducted among 100 prominent neonatologists from 74 centers and 103 prominent cardiologists from 75 centers. Among the cardiologists, approximately 50% were interventionists who perform transcatheter PDA closures (TCPC). Fisher's exact test was performed to compare practice variations among neonatologists and cardiologists. A potentially biased audience including a combination of health care providers belonging to cardiology, neonatology, and surgery were also surveyed during the International PDA Symposium. The results of this survey were not included for statistical comparison, due to this audience being potentially influenced by the Symposium. RESULTS Statistically significant differences were identified between neonatologists and cardiologists regarding the impact of PDA closure on morbidity and mortality, with 80% cardiologists responding that it does vs 54% of neonatologists (P < 0.001), the need for PDA closure (P < .001), and the preferred method of PDA closure if indicated (P < .001). There was agreement between neonatologists and cardiologists on symptomatic therapy; however more neonatologists favored watchful waiting over intervention in contrast to more cardiologists favoring intervention over observation (77% vs 95%, P < .001). Survey responses also identified a need for further training and research on TCPC. CONCLUSION Neonatologists and cardiologists have notable differences in managing PDA, and continued discussion across cardiology and neonatology has the potential to facilitate more of a consensus on best management practices. Further investigation is needed to identify outcomes in transcatheter PDA closure, particularly in ELBW infants.

Abstract
OBJECTIVES The authors sought to assess the intermediate-term effects of percutaneous placed valves in the branch pulmonary artery (PA) position. BACKGROUND Most patients with large right ventricular outflow tracts (RVOTs) are excluded from available percutaneous pulmonary valve options. In some of these patients, percutaneous branch PA valve implantation may be feasible. The longer-term effects of valves in the branch PA position is unknown. METHODS Retrospective data were collected on patients with significant pulmonary regurgitation who had a percutaneous branch PA valve attempted. RESULTS Percutaneous branch PA valve implantation was attempted in 34 patients (18 bilateral and 16 unilateral). One-half of the patients were in New York Heart Association (NHYA) functional class III or IV pre-implantation. There were 2 failed attempts and 6 procedural complications. At follow-up, only 1 patient had more than mild valvar regurgitation. The right ventricular end-diastolic volume index decreased from 147 (range: 103 to 478) ml/m2 to 101 (range: 76 to 429) ml/m2, p < 0.01 (n = 16), and the right ventricular end-systolic volume index decreased from 88.5 (range: 41 to 387) ml/m2 to 55.5 (range: 40.2 to 347) ml/m2, p < 0.01 (n = 13). There were 5 late deaths. At a median follow-up of 2 years, all other patients were in NYHA functional class I or II. CONCLUSIONS Percutaneous branch PA valve implantation results in a reduction in right ventricular volume with clinical benefit in the intermediate term. Until percutaneous valve technology for large RVOTs is refined and more widely available, branch PA valve implantation remains an option for select patients.

Abstract
OBJECTIVES This study sought to evaluate the safety, feasibility, and outcomes of transcatheter pulmonary valve replacement (TPVR) in conduits ≤16 mm in diameter. BACKGROUND The Melody valve (Medtronic, Minneapolis, Minnesota) is approved for the treatment of dysfunctional right ventricular outflow tract (RVOT) conduits ≥16 mm in diameter at the time of implant. Limited data are available regarding the use of this device in smaller conduits. METHODS The study retrospectively evaluated patients from 9 centers who underwent percutaneous TPVR into a conduit that was ≤16 mm in diameter at the time of implant, and reported procedural characteristics and outcomes. RESULTS A total of 140 patients were included and 117 patients (78%; median age and weight 11 years of age and 35 kg, respectively) underwent successful TPVR. The median original conduit diameter was 15 (range: 9 to 16) mm, and the median narrowest conduit diameter was 11 (range: 4 to 23) mm. Conduits were enlarged to a median diameter of 19 mm (29% larger than the implanted diameter), with no difference between conduits. There was significant hemodynamic improvement post-implant, with a residual peak RVOT pressure gradient of 7 mm Hg (p < 0.001) and no significant pulmonary regurgitation. During a median follow-up of 2.0 years, freedom from RVOT reintervention was 97% and 89% at 2 and 4 years, respectively, and there were no deaths and 5 cases of endocarditis (incidence rate 2.0% per patient-year). CONCLUSIONS In this preliminary experience, TPVR with the Melody valve into expandable small diameter conduits was feasible and safe, with favorable early and long-term procedural and hemodynamic outcomes.

Abstract
BACKGROUND Traditional approaches to pediatric cardiac catheterization have relied on femoral venous access. Upper- extremity venous access may enable cardiac catheterization procedures to be performed safely for diagnostic and interventional catheterizations. The objective of this multicenter study was to demonstrate the feasibility and safety of upper-extremity venous access in a pediatric cardiac catheterization laboratory. METHODS A retrospective chart review of all patients who underwent cardiac catheterization via upper-extremity vascular access was performed. RESULTS Eighty-two cardiac catheterizations were attempted via upper-extremity vein on 72 patients. Successful access was obtained in 75 catheterizations (91%) in 67 patients. Median age at catheterization was 18.79 years (interquartile range [IQR], 13.02-32.75 years; n = 75) with a median weight of 59.4 kg (IQR, 43.3-76.5 kg; n = 75). The youngest patient was 4.1 months old, weighing 4.3 kg. Local anesthesia or light sedation was utilized in 46 procedures (61%). Diagnostic right heart catheterization was the most common procedure (n = 65; 87%), with intervention performed via the upper extremity in 8 cases (11%). Median fluoroscopy time was 10.02 min (IQR, 2.87-36.26 min; n = 75), with dose area product/kg of 3.765 μGy•m²/kg (IQR, 0.74-34.12 μGy•m²/kg; n = 64). Median sheath duration time was 48 min (IQR, 19.5-147 min; n = 57) and median total procedure time was 116 min (IQR, 80.5-299 min; n = 65). Median length of stay for outpatient procedures was 5.37 hr (IQR, 4.25-6.92 hr; n = 27). There were no procedural complications. CONCLUSION Upper-extremity venous access is a useful, feasible, and safe modality for cardiac catheterization in the pediatric cardiac catheterization laboratory.

Abstract
In the era of neoadjuvant and adjuvant chemotherapy, extrapulmonary involvement by high-grade osteosarcoma (HGOS) is rare. Importantly however, HGOS metastasis in the form of cardiovascular tumor thrombus portends a dismal prognosis. Thus, prompt and accurate identification of tumor thrombus is crucial. We report here two unique cases of recurrent HGOS, presenting as thrombotic events, in order to increase awareness and index of suspicion among practitioners regarding this presentation. Additionally, we review 14 previously reported pediatric cases of cardiovascular metastatic HGOS.

Abstract
OBJECTIVES We aimed to assess the experience using a percutaneous axillary artery approach for insertion of arterial ductal stents in patients with critical right ventricular outflow tract lesions at two tertiary pediatric cardiology centers. BACKGROUND Patent ductus arteriosus stenting is an accepted palliative alternative to BT shunts for neonates with critical right heart lesions. Access to tortuous ductus' may be challenging via the femoral artery, whereas the carotid artery presents a low risk of stroke. Recently, the axillary artery has been utilized for access in these patients. METHODS We performed a retrospective review of neonates who underwent stent placement or angioplasty using percutaneous axillary artery approach at two tertiary care centers from October 2016 to November 2018. Medical records were reviewed to ascertain demographic, clinical, and outcome data. RESULTS Axillary artery access was performed in 20 patients (16 primary ductal stents and 4 re-interventions) at a median (IQR) procedural weight of 3.4 (3-3.9) kg. Median (IQR) procedural time was 110 (75-150) min. The median (IQR) ICU stay and intubation times were 14 (0-94) hr and 5 (0-40) hr, respectively. There were three access-related vascular complications which were managed conservatively with no long-term effects. Two patients subsequently died due to non-procedure related causes. CONCLUSIONS Ductal stenting via a percutaneous axillary artery approach is a viable option in neonates with critical right ventricular outflow tract lesions. This approach provides an additional access site for PDA stenting which may be utilized in patients with vertical duct morphology.

Abstract
BACKGROUND In infants with ductal-dependent pulmonary blood flow, initial palliation with patent ductus arteriosus (PDA) stent or modified Blalock-Taussig (BT) shunt have comparable mortality but discrepant length of stay, procedural complication rates and reintervention burdens, which may influence cost. The relative economic impact of these palliation strategies is unknown. METHODS AND RESULTS Retrospective study of infants with ductal-dependent pulmonary blood flow palliated with PDA stent (n=104) or BT shunt (n=251) from 2008 to 2015 at 4 centers of the Congenital Catheterization Research Collaborative. Inflation-adjusted inpatient hospital costs were calculated for first year of life using Pediatric Health Information System data. Costs derived from outpatient catheterizations not in Pediatric Health Information System were imputed. Costs were compared using propensity score-adjusted multivariable models, to account for baseline differences between groups. After propensity score adjustment, first year of life costs were significantly lower in PDA stent ($215 825 [190 644-244 333]) than BT shunt ($249 855 [230 693-270 609]) patients ( P=0.05). After addition of imputed costs, first year of life costs were not significantly different between PDA stent ($226 403 [200 274-255 941]) and BT shunt ($252 072 [232 955-272 759]) groups ( P=0.15). Patient characteristics associated with higher costs included: younger gestational age, genetic syndrome, noncardiac diagnoses, procedural complications, extracorporeal membrane oxygenation, duration of ventilation, intensive care unit and hospital length of stay and reintervention ( P≤0.02 for all). CONCLUSIONS In this first multicenter comparative cost study of PDA stent or BT shunt as palliation for infants with ductal-dependent pulmonary blood flow, adjusted for baseline differences, PDA stent was associated with lower to equivalent costs over the first year of life. Combined with previous evidence suggesting clinical noninferiority, these findings suggest that PDA stent provides competitive health care value.

Abstract
BACKGROUND AND PURPOSE Retinoblastoma is the most common pediatric ocular neoplasm. Multimodality treatment approaches are commonplace, and selective ophthalmic artery chemosurgery has emerged as a safe and effective treatment in selected patients. Minimizing radiation dose in this highly radiosensitive patient cohort is critical. We explore which procedural factors affect the radiation dose in a single-center cohort of children managed in the UK National Retinoblastoma Service. MATERIALS AND METHODS A retrospective review was performed of 177 selective ophthalmic artery chemosurgery procedures in 48 patients with retinoblastoma (2013-2017). Medical records, angiographic imaging, and radiation dosimetry data (including total fluoroscopic screening time, skin dose, and dose-area product) were reviewed. RESULTS The mean fluoroscopic time was 13.5 ± 13 minutes, the mean dose-area product was 11.7 ± 9.7 Gy.cm2, and the mean total skin dose was 260.9 ± 211.6 mGy. One hundred sixty-three of 177 procedures (92.1%) were technically successful. In 14 (7.9%), the initial attempt was unsuccessful (successful in 13/14 re-attempts). Screening time and radiation dose were associated with drug-delivery microcatheter location and patient age; screening time was associated with treatment cycle. CONCLUSIONS In selective ophthalmic artery chemosurgery, a microcatheter tip position in the proximal or ostial ophthalmic artery and patient age 2 years or younger were associated with reduced fluoroscopic screening time and radiation dose; treatment beyond the first cycle was associated with reduced fluoroscopic screening time.
