RESUMO
Cardiovascular disease is a leading cause of morbidity and mortality in individuals with Down syndrome. Congenital heart disease is the most common cardiovascular condition in this group, present in up to 50% of people with Down syndrome and contributing to poor outcomes. Additional factors contributing to cardiovascular outcomes include pulmonary hypertension; coexistent pulmonary, endocrine, and metabolic diseases; and risk factors for atherosclerotic disease. Moreover, disparities in the cardiovascular care of people with Down syndrome compared with the general population, which vary across different geographies and health care systems, further contribute to cardiovascular mortality; this issue is often overlooked by the wider medical community. This review focuses on the diagnosis, prevalence, and management of cardiovascular disease encountered in people with Down syndrome and summarizes available evidence in 10 key areas relating to Down syndrome and cardiac disease, from prenatal diagnosis to disparities in care in areas of differing resource availability. All specialists and nonspecialist clinicians providing care for people with Down syndrome should be aware of best clinical practice in all aspects of care of this distinct population.

Noninvasive functional assessment of systemic right ventricles (RV) in hypoplastic left heart syndrome (HLHS) is challenging. This study aimed to compare pediatric cardiologists' current noninvasive imaging practices to those reported in 2013. A web-based survey was distributed to pediatric cardiologists via various listservs which queried timing of echocardiograms during HLHS palliative stages and measurements of RV function. Demographics of 156 participants who completed the 2023 survey were similar to survey participants in 2013 (n = 222). Respondents were mostly male (62%), echocardiographers (48%), in university-based practice (67%) in North America (95%). Echocardiograms were predominantly obtained monthly during interstage I (41%), every 6 months during interstage II (56%), and every year post-Fontan (68%), which is consistent from 2013. Routine cardiac magnetic resonance imaging (cMRI) significantly increased in interstage II (8.2%, 17%) and post-Fontan (24%, 56%) populations, respectively. Qualitative assessment (41%), ejection fraction (EF) by 3D (20%), fractional area change (16%), and RV strain/strain rate (13%) were preferred methods for systolic assessment, whereas a plurality of respondents (41%) did not believe RV diastolic measurements were valid. The largest gap between currently obtained and desired measurements existed for EF by 3D (46.5% points) and RV strain/strain rate (44.5% points). No differences existed between imagers compared to non-imagers. Variability in evaluating HLHS patients continues among pediatric cardiologists compared to 10 years ago. Qualitative assessment remains the primary RV systolic functional evaluation. Providers do not rely on quantitative RV diastolic function assessments in HLHS patients. Use of cMRI is increasing for RV functional analysis.
RESUMO
Adolescents with congenital heart disease (CHD) have elevated risk for acquired cardiovascular complications, increasing their vulnerability to e-cigarette-related health harms. Impulsivity and risky decision-making have been associated with adolescent substance use, but the relationships between these factors and e-cigarette-related outcomes among cardiovascular at-risk adolescents with CHD are unknown. This cross-sectional study aimed to (a) determine the associations of impulsivity and risky decision-making with e-cigarette-related outcomes (i.e. susceptibility, ever use, perceptions of harm and addictiveness) via variable-oriented analysis (logistic regression), (b) identify groups of adolescents with similar profiles of impulsivity and risky decision-making via exploratory person-oriented analysis (latent profile analysis; LPA), and (c) examine differences on e-cigarette-related outcomes between profile groups. Adolescents aged 12 to 18 years with CHD (N = 98) completed a survey assessing impulsivity facets (Short UPPS-P) and e-cigarette-related outcomes and were administered a risky decision-making task (Iowa Gambling Task, Version 2; IGT2). In variable-oriented analyses, impulsivity facets (negative urgency, positive urgency, lack of premeditation) but not risky decision-making were associated with e-cigarette susceptibility and ever use. The exploratory LPA identified two groups with similar patterns of responding on the Short UPPS-P and IGT2 labeled "Low Impulsivity" and "High Impulsivity," which were primarily characterized by significant differences in negative and positive urgency. Adolescents in the High Impulsivity group had increased odds of e-cigarette susceptibility but not ever use compared to the Low Impulsivity group. This work indicates that strategies to prevent e-cigarette use among adolescents with CHD may be enhanced by addressing impulsivity, particularly negative and positive urgency.
RESUMO
OBJECTIVE: Adolescents with congenital heart disease (CHD) are exposed to disease-related stressors and have elevated risk for cardiovascular and cognitive complications that are exacerbated by e-cigarettes and marijuana. The aims of this cross-sectional study are to: (1) identify the association between perceived global and disease-related stress and susceptibility to e-cigarettes and marijuana, (2) determine if the association between stress and susceptibility differs by gender, and (3) explore the association between stress and ever use of e-cigarettes and marijuana among adolescents with CHD. METHODS: Adolescents with CHD (N = 98; aged 12-18 years) completed self-report measures of susceptibility to/ever use of e-cigarettes and marijuana and global and disease-related stress. RESULTS: Susceptibility to e-cigarettes and marijuana was reported by 31.3% and 40.2% of adolescents, respectively. Ever use of e-cigarettes and marijuana was reported by 15.3% and 14.3% of adolescents, respectively. Global stress was associated with susceptibility to and ever use of e-cigarettes and marijuana. Disease-related stress was associated with susceptibility to marijuana. Females reported more global and disease-related stress than males, but the association of stress with susceptibility to e-cigarettes and marijuana did not differ by gender. CONCLUSIONS: Susceptibility to e-cigarettes and marijuana is common among adolescents with CHD and is associated with stress. Future work to examine the longitudinal associations between susceptibility, stress, and use of e-cigarettes and marijuana is warranted. Global stress may be an important consideration in the development of strategies to prevent these risky health behaviors among adolescents with CHD.

BACKGROUND: Evidence-based anticoagulation programs usually serve a local, adult patient population. Here we report outcomes for a regional combined pediatric-adult program. AIMS: The aims of this study were: (1) Compare the pre- vs. post-implementation quality of therapy (% time in therapeutic range (%TTR) and compliance). (2) Assess anticoagulant-relevant outcomes (bleeding and thrombotic complications). METHODS: Data were collected for the years 2014-2019. Rosendaal linear interpolation was used to calculate %TTR. Bleeding complications were categorized using ISTH-SSC standard nomenclature and new thrombotic events were reviewed. RESULTS: The patients were divided into a long-term warfarin group (N = 308), 80.2% of whom had cardiac-related therapeutic indications (median age 24y), and a second group (N = 114) comprised of short-term and non-warfarin long-term anticoagulation (median age 16y). Median %TTR for those on long-term warfarin was 78.9%. The incidence of major and clinically relevant non-major bleeding events was 1.65 and 2.43 /100 person-years of warfarin use, respectively. Thromboembolism (TE) incidence was 0.78/100 patient-years of warfarin use. Neither bleeding nor thrombosis was associated with %TTR (p = 0.48). Anticoagulant indication was the only variable associated with bleeding risk (p = 0.005). The second group had no on-therapy TE events but 7.9% experienced bleeding. Complete data were available for a randomly sampled pre-program warfarin group (N = 26). Median %TTR improved from 17.5 to 87% pre- vs. post-implementation. Similarly, compliance (defined as ≥ 1 INR/month) improved by 34.3%. CONCLUSIONS: In conclusion, this program significantly improved and sustained %TTR and compliance. The lack of association between bleeding and thrombosis events and %TTR may be related to the high median %TTR (> 70%) achieved by this approach.

Fetal echocardiograms (F-echo) are recommended in all pregnancies when the fetus has Down syndrome (DS) even if there was a prior obstetric scan (OB-scan) that was normal. The utility of a screening F-echo in this high-risk population when an OB-scan is normal is unknown. Goal of this study was to evaluate if any diagnosis of a critical congenital heart disease (CHD) was missed in a fetus with DS who had a normal OB-scan. Secondary goal was to determine if any CHD was missed postnatally when an OB-scan was read as normal. Retrospective chart review of all fetuses that had a F-echo whose indication was DS between 1/1/2010 to 6/30/2022 was performed. Fetuses were included if they had an OB-scan that was read as normal and had a F-echo. Postnatal transthoracic echocardiogram (pTTE) was reviewed when available. Critical CHD was defined as CHD requiring catheterization or surgical intervention < 1 month of age. One hundred twenty-two F-echo on fetuses with DS were evaluated, of which 48 met inclusion criteria. OB-scan was performed at 20.4 ± 4.5 weeks gestational age and F-echo was performed at 24.0 ± 4.6 weeks gestational age. No patient with a normal OB-scan had a diagnosis of a critical CHD by F-echo (n = 48, negative predictive value = 100%). Evaluating those patients that had an OB-scan and a pTTE (n = 38), 14 patients were diagnosed with CHD (muscular ventricular septal defect (VSD) n = 5, perimembraneous VSD n = 3, secundum atrial septal defect (ASD) n = 2, primum ASD n = 1, transitional atrioventricular septal defect (AVSD) n = 2, and aortic valve abnormality n = 1; negative predictive value = 63.2%). F-echo correctly diagnosed 4 of the 14 missed OB-scan CHD (perimembraneous VSD n = 2, muscular VSD n = 1, and transitional AVSD n = 1). Critical CHD was not missed with a normal OB-scan in this high-risk population. F-echo also missed the majority of CHD when an OB-scan was read as normal. The cost/benefit of screening F-echo in fetuses with DS should be evaluated if a normal OB-scan has been performed, considering all these patients would have a pTTE performed per guidelines.

NEONATE score > 17 has been proposed as a risk factor for interstage mortality/cardiac transplant (IM/T) for patients with single ventricle physiology. Hybrid procedure is assigned 6 points, the highest possible score for that surgical variable. Most centers reserve the hybrid procedure for high-risk patients. Goal of this study was to evaluate the NEONATE score at a center that routinely performs the hybrid procedure. Retrospective chart review of patients undergoing the hybrid procedure was performed (2008-2021). Demographics and variables used for the NEONATE score were collected. Maximization of Youden's J Statistic used to determine cohort-specific optimal threshold for patients undergoing comprehensive Stage II procedure (H-CSII) versus those with IM/T (H-IM/T). Total of 120 patients met inclusion criteria (H-CSII = 105, H-IM/T = 15). Gestational age was median 39 weeks (IQR 38, 39) and birth weight was 3.18 kg (2.91, 3.57). No patient was discharged with opiates or required post-operative extracorporeal circulatory support. Optimal threshold, as selected by maximizing Youden's J Statistic, was 22. Score > 22 had a positive predictive value of 0.33 (95% CI 0.12-0.62), negative predictive values of 0.90 (95% CI 0.83-0.95), and accuracy of 0.83 (95% CI 0.75-0.90) for IM/T. At a center that routinely performs the hybrid procedure, value of > 22 had the highest accuracy. This suggests that the hybrid procedure is not necessarily intrinsically a risk-factor for IM/T, but rather patient selection for the hybrid procedure may play a larger role at centers that do not routinely perform this procedure.

We sought to examine current practices and changes in practice regarding initial counseling for families of patients with hypoplastic left heart syndrome (HLHS) given the evolution of options and outcomes over time. Counseling (Norwood with Blalock-Taussig-Thomas shunt (NW-BTT), NW with right ventricle to pulmonary artery conduit (NW-RVPA), hybrid palliation, heart transplantation, or non-intervention/hospice (NI)) for patients with HLHS were queried via questionnaire of pediatric care professionals in 2021 and compared to identical questionnaire from 2011. Of 322 respondents in 2021 (39% female), 299 respondents were cardiologists (92.9%), 17cardiothoracic surgeons (5.3%), and 6 were nurse practitioners (1.9%). Respondents were largely from North America (96.9%). In 2021, NW-RVPA procedure was the preferred palliation for standard risk HLHS patient (61%) and was preferred across all US regions (p < 0.001). NI was offered as an option by 71.4% of respondents for standard risk patients and was the predominant strategy for patients with end-organ dysfunction, chromosomal abnormality, and prematurity (52%, 44%, and 45%, respectively). The hybrid procedure was preferred for low birth-weight infants (51%). In comparison to the identical 2011 questionnaire (n = 200), the NW-RVPA was endorsed more in 2021 (61% vs 52%, p = 0.04). For low birth-weight infants, hybrid procedure was more recommended than in 2011 (51% vs 21%, p < 0.001). The NW-RVPA operation is the most recommended strategy throughout the US for infants with HLHS. The hybrid procedure for low birth-weight infants is increasingly recommended. NI continues to be offered even in standard risk patients with HLHS.

BACKGROUND: Individuals with congenital heart defects are at increased risk for developing further cardiovascular complications, which can be mitigated by increasing physical activity. Given that positive health behaviors begin declining during older adolescence, it is vital to promote lifestyle changes in this population. PURPOSE: The current study aims to (a) determine the feasibility/acceptability of the Congenital Heart Disease Physical Activity Lifestyle (CHD-PAL) intervention among adolescents (ages 15-18) with moderate and complex congenital heart defects, and (b) estimate the preliminary efficacy of CHD-PAL for increasing time spent in moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness and decreasing sedentary behavior. METHODS: Eligible participants were randomized into either CHD-PAL (eight 30-min videoconferencing sessions over 20 weeks with an interventionist + Fitbit + exercise prescription) or a comparator (Fitbit + exercise prescription). RESULTS: Sixty adolescents were randomized (76% recruitment rate; 94% of participants were retained from baseline to follow-up). Most adolescents (73%) and their parents/guardians (76%) reported that the trial was enjoyable. While there was no effect of arm on change in MVPA, sedentary behavior, or cardiorespiratory fitness for the entire sample, among those who engaged in <21 min of MVPA on average at baseline, adolescents in the CHD-PAL intervention had an increase of 16 min/day of MVPA more than comparators (d = 0.90). CONCLUSIONS: The CHD-PAL intervention warrants examination in a larger trial to establish efficacy among those adolescents with a congenital heart defect who engage in <21 min of MVPA/day and should include follow-up assessments to examine effect durability. CLINICAL TRIALS REGISTRATION: NCT03335475.

OBJECTIVE: The current study aimed to (a) describe moderate-to-vigorous physical activity (MVPA), sedentary behavior (SB), and cardiorespiratory fitness (VO2Peak) via objective assessment among adolescents with congenital heart disease (CHD), (b) examine gender differences on MVPA, SB, VO2Peak, and the Theory of Planned Behavior elements, and (c) identify whether gender moderates the relationships between the Theory of Planned Behavior elements and MVPA, SB, and VO2Peak. METHODS: Adolescent CHD survivors (N = 86; ages 15-18 years) wore an accelerometer to assess MVPA and SB, underwent an exercise stress test to assess VO2Peak, and completed a survey of the Theory of Planned Behavior elements as measured by perceived benefits (attitudes), family/friend support and perceived norms (social norms), and self-efficacy and barriers (perceived behavioral control) to engaging in physical activity. RESULTS: On average, CHD survivors engaged in 22.3 min (SD = 15.3) of MVPA/day and 9 hr of SB/day (M = 565.8, SD = 102.5 min). Females engaged in less MVPA but not more SB had a lower mean VO2Peak, reported lower self-efficacy, and perceived greater barriers than males. In a regression model, barriers explained unique variance in MVPA and VO2Peak, but the relationship between barriers and MVPA/VO2Peak did not vary by gender. Self-efficacy did not explain unique variance in MVPA and VO2Peak when included in a model with gender and barriers. CONCLUSIONS: Family/friend support for physical activity engagement may be an important consideration when developing physical activity interventions for adolescent CHD survivors. The role of gender differences in self-efficacy and perceived barriers on physical activity engagement warrants further investigation.

Minimal data exist about the incidence and risk factors for arch intervention after comprehensive stage II (CSII). Goal of this study was to document incidence of arch interventions after CSII and determine if any differences existed between those who underwent an arch intervention (aiCSII) versus those did not have an intervention. Single-center retrospective chart review of all hypoplastic left heart syndrome patients who underwent a CSII between 6/1/2005 and 2/1/2020 was performed. Univariate analysis was conducted in addition to principal components analysis (PCA). One hundred patients were evaluated. Sixteen patients underwent 24 arch interventions. Age at initial arch reintervention was 1.3 ± 1.2 years (median 1.0 years, range 0.5-2.2 years). Univariate analysis showed that the aiCSII group were more likely to be female, to have had a retrograde arch intervention post-hybrid procedure, and to be younger at time of CSII. On echocardiograms, aiCSII group had significantly higher pre-CSII patent ductus arteriosus velocities, arch velocities on their 1st post-operative and discharge study post-CSII, and arch velocities pre-Fontan. Gradients were higher in the aiCSII via pre-Fontan catheterization. With PCA, echocardiographic and catheterization data remained significantly associated with aiCSII versus those who did not undergo an arch intervention (OR = 4.5 (1.9, 19.8), p = 0.008). Incidence of arch intervention post-CSII was 16%. Echocardiographic arch velocities during the CSII hospitalization were the strongest predictors for subsequent aortic arch interventions. Further studies are needed to determine any modifiable variables that may reduce the incidence of arch interventions.

BACKGROUND: Non-invasive prenatal screening (NIPS) has fundamentally changed the screening process for Down syndrome (DS). Rates of complex congenital heart defects (CHD) have decreased in international studies but whether these shifts exist in the US is unknown. METHODS: Encounters for neonates with DS from 2007 to 2018 were obtained from the Pediatric Health Information System database. CHD were categorized as complex CHD, atrioventricular septal defects (AVSD), ventricular septal defects (VSD), and tetralogy of Fallot (TOF). Comparisons were made between pre-NIPS era (2007-2010) vs. post-NIPS era (2014-2018) and between states with low vs. high access to pregnancy termination as described by the Guttmacher Institute. RESULTS: Among 9122 patients, 6% had complex CHD, 22% had an AVSD, 22% had a VSD, and 4% had TOF. No difference in proportions of CHD was seen between eras. A small difference was observed in the proportion of AVSD between states with low vs. high access to pregnancy termination (23 vs. 17%, p < 0.001). CONCLUSIONS: The proportion of CHD in patients with DS appears to be stable despite widespread adoption of NIPS in the US. Variations were observed between states with low vs. high access to pregnancy termination. Population based studies are needed to fully evaluate the current epidemiology of CHD in DS. IMPACT: Through investigation of the Pediatric Health Information System database, this study assesses contemporary epidemiology of congenital heart disease among patients with Down syndrome. It has been suggested that improved prenatal screening for Down syndrome has altered the cardiac phenotype in international populations. Whether a similar shift also exists in the United States is unknown. In a contemporary United States cohort, a shift in the proportion or type of heart defects over the past decade was not observed. Regional differences in the proportion of heart defects were seen and may be due to differential access to prenatal care.

AIMS: Cylinder mitral valve construct (cMVC) is new technique for replacing the mitral valve compared to more traditional mitral valve replacement (MVR) procedures. Goal of this study was to describe echocardiographic changes over time in patients undergoing a cMVC. Secondary goal was to compare echocardiographic changes in patients that underwent a cMVC to a group of patients that underwent a MVR. METHODS: Retrospective analysis of patients undergoing a cMVC was performed. Demographics, discharge echocardiogram, and recent echocardiogram vales were evaluated. Age matched patients undergoing a MVR were assessed. Discharge and recent echocardiographic parameters were compared within the cMVC group. cMVC and MVR values were compared between groups. RESULTS: Five cMVC patients were studied. Age at surgery for the cMVC was 4.3 ± 4.2 years (median 2.2, .8-10.3 years). Time interval from hospital discharge echocardiogram to the most recent echocardiogram was 1.2 ± .7 years (median 1.0, .6-2.0 years). Mean mitral valve gradient significantly increased over time (3.6 ± 3.0 mm Hg vs 7.6 ± 2.9 mm Hg). There were significant improvements in left ventricular diameters, systolic sphericity index, shortening fraction, and ejection fraction over time. There were no significant differences in demographics, discharge echocardiogram values, and follow up echocardiogram values between the cMVC and MVR groups. CONCLUSION: In conclusion, echocardiographic indices of left ventricular function improved over time in patients undergoing cMVC. In addition, there were no significant differences between cMVC and MVR patients in echocardiographic values. Studies with a larger patient sample with longer follow up are needed to determine if cMVC continues to have comparable echocardiographic results to MVR.

INTRODUCTION: Transesophageal echocardiography (TEE) is frequently used in children with and without congenital heart disease when transthoracic echocardiography is inadequate for visualizing cardiac structures. Recent guidelines state relative contraindications of TEE include post-gastrostomy tube (GT) or Nissen fundoplication surgery. No data exist documenting the incidence of complications in this population after a TEE. Aim of this study was to document the incidence of abdominal complications after TEE in pediatric patients who previously had a GT or Nissen fundoplication. METHODS: Single institution retrospective study was performed evaluating patients from 2013 through 2020. Patients were included if they had previously undergone a GT or Nissen procedure and subsequently underwent a TEE procedure. Baseline demographics were obtained. Major (esophageal/gastric perforation, oropharyngeal dysphagia, GT displacement, and Nissen breakdown) and minor (abdominal pain, feeding intolerance, and GT leakage) complications were recorded. RESULTS: Total of 34 patients underwent 48 TEE procedures. Age was 6.2 ± 6.6 years (median 3.0 years, .4 - 23.0 years) and weight was 18.5 ± 14.8 kgs (median 12.4 kgs, 4.2 - 57.5 kg) at time of TEE. Twenty-nine patients had congenital heart disease. Five patients had a Nissen fundoplication, 14 patients had a GT, and 15 patients had both procedures prior to the TEE. No patient had a major abdominal complication after the TEE. One patient had abdominal pain (2.1%), one patient had feeding intolerance and leakage around the GT site (2.1%), and two patients had leakage around the GT site (4.2%) after the TEE. Patients that experienced complications were significantly younger (1.7 ± 1.1 years vs. 6.6 ± 6.7 years, P < .01) and weighed less (8.7 ± 3.5 kg vs. 20.1 ± 15.5 kg, P < .01) than those that had no complications. All minor complications resolved with minimal interventions required. CONCLUSION: In this study, major abdominal complications did not occur after a TEE procedure in pediatric patients that had previous abdominal surgeries. The incidence of minor complications was relatively low and was easily remedied in this patient population. Though a relative contraindication by guidelines, TEE imaging, including transgastric views, can be performed relatively safely in pediatric patients with prior abdominal surgeries if needed.

Post-pericardiotomy syndrome (PPS) is a common inflammatory process following cardiac surgery, in which the pericardial space was opened. Pericardial effusion (PE) is a common manifestation in PPS; however, coronary artery dilation is not associated with PPS. Inflammatory vasculitis in children are known to cause coronary dilation, in conditions such as in Kawasaki Disease (KD). We report a patient with PPS and concomitant coronary dilation by transthoracic echocardiography (TTE) following repair of her ventricular septal defect (VSD).

BACKGROUND: Yield of serial echocardiography in fetuses with atrioventricular septal defects (fAVSD) has not been well defined. The goal of this study was to document if any major changes occurred from initial fetal to initial postnatal echocardiogram in uncomplicated fAVSD. METHODS: fAVSD were excluded if initial fetal scan documented complex CHD or any concerns. Changes in ventricular function, valvular regurgitation, or diagnosis between first fetal and first postnatal echocardiogram were recorded. RESULTS: Fifty-seven fAVSD met criteria. Ninety-six fetal echocardiograms were done in 57 patients. Initial fetal scan was performed at 24.3 ± 3.7 weeks of estimated gestational age. All fAVSD had normal function, 38 had no atrioventricular valve regurgitation (AVVR), and 19 had mild AVVR. First postnatal echocardiogram was performed at 6.3 ± 15.3 days. Fifty-six patients had normal function, 1 patient had mild dysfunction, 16 patients had no AVVR, 36 had mild AVVR, and 5 had moderate AVVR. Three patients (5%) had an improvement in AVVR by one degree, 27 patients (47%) had no change in AVVR, 24 patients (42%) had an increase in AVVR by one degree, and 3 patients (5%) had an increase in AVVR by two degrees. There was no major missed anatomical diagnosis from first prenatal to first postnatal echocardiogram. CONCLUSION: In fAVSD that had no concerns on their initial fetal echocardiogram, the majority of patients had no major changes noted between their initial fetal echocardiogram and their first postnatal echocardiogram. Repeat fetal echocardiograms may not necessarily be needed in this cohort of patients.

A fetal echocardiogram noted valvar pulmonary atresia vs critical pulmonary valve stenosis, confluent pulmonary arteries, patent ductus arteriosus, and an apical muscular ventricular septal defect vs coronary sinusoid. Postnatal echocardiogram documented an absent pulmonary valve, coronary artery fistula to the right ventricle, confluent pulmonary arteries, and a patent ductus arteriosus. Catheterization confirmed the postnatal echocardiographic findings except there was no antegrade flow from the right ventricle to the pulmonary arteries. Close evaluation of all imaging modalities revealed the final diagnosis of absent pulmonary valve with a double-chambered right ventricle with no egress from the right ventricle to pulmonary artery.

Mitral valve replacement (MVR) in children under 2 years is associated with significant morbidity and mortality. Decellularized porcine intestinal submucosa is a commercially available formulation of an extracellular matrix (ECM) with an indication for cardiac tissue repair. The present study reports our experience using ECM cylinder valves in patients for MVR. A retrospective review of patients under 2 years who underwent ECM custom-made cylinder mitral valve (ECM-MV) replacement was performed. Clinical, demographic, operative and post-operative follow-up data, including serial echocardiographic data are presented. Eight patients (age 5.6 ± 1.6 months; weight: 6.0 ± 1.1 kg) were identified who underwent ECM-MVR. There was one in-hospital death and no major neurological events. Six patients underwent replacement of their cylinder valve with either a Melody valve inside the ECM-MVR (n = 3), a mechanical valve (n = 2), or a decellularized bovine pericardial cylinder valve (n = 1). The mean time to replacement surgery was 8.4 ± 2.6 months after ECM-MV. The indications for replacement of ECM-MV included mitral stenosis/regurgitation (n = 4) or dehiscence (n = 2). One remaining patient is 24 months from ECM-MV, with trivial regurgitation and no stenosis. Mitral valve creation using ECM is an option for MVR in pediatrics, avoiding anticoagulation, and provides a suitable construct for later placement of a Melody valve, extending surgical and non-surgical options. However, the durability of the native ECM-MV in the mitral position is concerning considering the high re-intervention rate in a relatively short time period. Further studies are needed to determine the longer-term outcomes of this valve in this complex patient population.

The optimal timing of clamping and cutting the umbilical cord at birth among infants with congenital heart disease (CHD) remains a subject of controversy and debate. The benefits of delayed umbilical cord clamping (DCC) among term infants without CHD are well described, but the evidence base for DCC among infants with CHD has not been characterized adequately. The goals of the present review are to: 1) compare outcomes of DCC versus early cord clamping (ECC) in term (≥37 weeks of gestation) infants; 2) discuss potential risk/benefit profiles in applying DCC among term infants with CHD; 3) use rigorous systematic review methodology to assess the quality and quantity of published reports on cord clamping practices among term infants with CHD; 4) identify needs and opportunities for future research and interdisciplinary collaboration. Our systematic review shows that previous trials have largely excluded infants with CHD. Therefore, the supposition that DCC is advantageous because it is associated with improved neurologic and hematologic outcome is untested in the CHD population. Given that CHD is markedly heterogeneous, to minimize unnecessary and potentially harmful cord clamping practices, identification of subgroups (single-ventricle, cyanotic lesions) most likely to benefit from optimal cord clamping practices is necessary to optimize risk/benefit profiles. The available evidence base suggests that contemporary, pragmatic, randomized controlled trials comparing DCC with ECC among infants with CHD are needed.
RESUMO
OBJECTIVES: To describe longer term outcomes for infants <6 kg undergoing percutaneous occlusion of the patent ductus arteriosus (PDA). STUDY DESIGN: This was a retrospective cohort study of infants <6 kg who underwent isolated percutaneous closure of the PDA at a single, tertiary center (2003-2017). Cardiopulmonary outcomes and device-related complications (eg, left pulmonary artery obstruction) were examined for differences across weight thresholds (very low weight, <3 kg; low weight, 3-<6 kg). We assessed composite measures of respiratory status during and beyond the initial hospitalization using linear mixed effects models. RESULTS: In this cohort of lower weight infants, 92 of 106 percutaneous occlusion procedures were successful. Median age and weight at procedure were 3.0 months (range, 0.5-11.1 months) and 3.7 kg (range, 1.4-5.9 kg), respectively. Among infants with pulmonary artery obstruction on initial postprocedural echocardiograms (n = 20 [22%]), obstruction persisted through hospital discharge in 3 infants. No measured variables were associated with device-related complications. Rates of oxygenation failure (28% vs 8%; P < .01) and decreased left ventricular systolic function (29% vs 5%; P < .01) were higher among very low weight than low weight infants. Pulmonary scores decreased (indicating improved respiratory status) following percutaneous PDA closure. CONCLUSIONS: Percutaneous PDA occlusion among lower weight infants is associated with potential longer term improvements in respiratory health. Risks of device-related complications and adverse cardiopulmonary outcomes, particularly among very low weight infants, underscore the need for continued device modification. Before widespread use, clinical trials comparing percutaneous occlusion vs alternative treatments are needed.
