The clinical outcomes of patients with chylothorax with prolonged drainage compared to prompt resolution have not been described. This is a retrospective cohort study across eight United States pediatric cardiac intensive care units (ICU). Patients < 18 years old treated for chylothorax within 30 days of cardiac surgery were included, excluding Fontan palliations. Patients with chest tube duration ≥ 14 days were classified as long chylothorax (LC) vs. < 14 days as short chylothorax (SC). Univariable and multivariable logistic regression modeled patient characteristics associated with LC vs. SC. 134 patients had chylothorax, and 51 (38%) were LC. The proportion of LC increased with surgical complexity. LC was diagnosed later and had longer duration of mechanical ventilation, and ICU and hospital lengths of stay. In-hospital mortality was not different between groups. On POD 7, chest tube output (CTO, ml/kg) difference between LC and SC was greatest, with an area under the receiver operating characteristic curve of 0.76 for CTO predicting chylothorax. By multivariable analysis, clinical events associated with LC were sepsis or CLABSI (adjusted odds ratio (aOR) 8.8), postoperative open sternum (aOR 3.3), and CTO > 20 ml/kg on POD 7 (aOR 7.3). High chest tube output on POD 7 may predict LC in children post-cardiac surgery. LC is associated with increased resource utilization and morbidity. Early identification of patients at risk for LC may allow for tailored treatment strategies and improved outcomes.","PeriodicalId":19814,"journal":{"name":"Pediatric Cardiology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143502550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prenatal detection is increasing due to advances in screening and fetal echocardiography. Postnatal outcomes remain variable. We describe our single-center experience of postnatal outcomes in prenatally detected vascular rings and evaluate factors associated with surgery. We performed a retrospective review of all fetal diagnoses of possible vascular ring evaluated between 2016 and 2023. Patients with significant intracardiac abnormalities, without postnatal data, or without confirmed postnatal diagnosis were excluded from postnatal analysis. Outcome variables included symptoms, tracheal/esophageal compression, and surgical repair. The prenatal cohort included 109 patients with 80% right aortic arch (RAA) and 20% double aortic arch (DAA). Of 72 patients in the postnatal cohort, 85% underwent computed tomography angiography (CTA) at median age of 2 months with 0.84 ± 0.34 mSv of radiation. On CTA, 69% had a diverticulum. Of those with RAA, 95% had an aberrant left subclavian. Most (79%) had airway abnormalities on CTA. Fifteen (21%) developed symptoms at median age of 5 months. Fifty-eight percent of patients underwent surgery at median age of 10 months, of which 33% were due to symptoms. On univariate analysis, DAA was associated with airway abnormalities on CTA and surgical repair. At 30-month follow up, 99% of patients remained asymptomatic. Prenatal diagnosis of vascular rings is associated with high rates of airway abnormalities, even in those without symptoms. Surgical repair was pursued in asymptomatic patients with DAA and airway abnormalities in our institution. As DAA is associated with airway abnormalities, these patients may require closer monitoring for future symptom development.","PeriodicalId":19814,"journal":{"name":"Pediatric Cardiology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143492773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their impact on late outcomes remains poorly understood. Our objective was to assess whether long-term studies after the Fontan incorporated the impact of arrhythmia characteristics on outcome. We reviewed the literature since 2005 for studies evaluating the impact of multiple risk factors on long-term outcomes and mortality after the Fontan. Studies focusing only on one or two risk factors (including arrhythmias) and those with a mean follow-up < 10 years were excluded. Of the 17 studies analyzed, only six mentioned rhythm at follow-up. Nine lumped all arrhythmias (tachyarrhythmia, bradyarrhythmia, paced rhythm, early and late arrhythmia) into one single category. Only eight of the 17 studies reported the incidence of tachyarrhythmias in detail and only two studies described bradyarrhythmias in detail as sinus or atrioventricular (AV) node dysfunction subgroups. Five studies reported on treatment of tachyarrhythmias including Fontan revision surgeries, catheter ablation, pacemaker placement and or the use of antiarrhythmic drugs. However, only one included information on the impact of treatment on outcomes. Out of 15 studies that conducted a multivariate analysis of Fontan outcomes, arrhythmia was included in the univariate model in 14 and in the multivariate model in 9. Overall, we found most studies on late outcomes after the Fontan do not include rhythm and arrhythmia characteristics in data collection and analysis. Incorporating more granular rhythm information in large databases and in multivariate analyses will help better determine and contextualize the impact of arrhythmias on outcomes after the Fontan.","PeriodicalId":19814,"journal":{"name":"Pediatric Cardiology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143472786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This letter commends the authors for their efforts to correlate pre-transplant echocardiographic parameters with post-operative outcomes, which holds promise for advancing pediatric hepatology and cardiology. However, this study also raises several concerns regarding methodology and interpretation. Key limitations include potential selection bias from single-center recruitment and exclusion criteria, reliance solely on STE without incorporating advanced imaging modalities such as 3D echocardiography or cardiac MRI, and lack of consideration for socioeconomic and geographic factors that influence outcomes. Additionally, the study's cross-sectional design and limited adjustment for confounding variables, such as nutritional status and infections, restrict its ability to provide dynamic and comprehensive insights. Addressing these limitations through future research-encompassing diverse populations, advanced imaging, longitudinal data, and robust control of variables-will enhance the reliability and applicability of findings in this critical domain.","PeriodicalId":19814,"journal":{"name":"Pediatric Cardiology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143449892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global constructive work, index, and efficiency were progressively worse with increasing heart rates. In this prospective pilot study, we demonstrated that myocardial work indices differ depending on myocardial activation pattern and at different heart rates in pediatric patients.

Percutaneous pulmonary valve implantation (PPVI) with self-expandable valves offers a promising alternative, especially for enlarged right ventricular Queryoutflow tracts (RVOT). Five RVOT types identified in patients with Tetralogy of Fallot reflect anatomical variations due to disease and prior surgeries. This study assesses the Pulsta THV® valve's in vitro hemodynamic performance across these RVOT morphologies using 3D-printed models. Five RVOT morphologies were recreated as 3D models from patient-specific imaging data. The Pulsta THV® valves, available in 28, 30, and 32 mm sizes, were evaluated using the ViVitro Pulse Duplicator System at three cardiac outputs (2, 3.5, and 5 L/min). Hemodynamic performance was assessed by measuring regurgitation rates and pressure gradients in the left and right pulmonary arteries. The Pulsta THV® performed optimally in RVOT Types 1 and 2, demonstrating lower regurgitation rates and pressure gradients, particularly with larger valve sizes. Conversely, RVOT Types 3 and 5 showed increased pressure gradients and hemodynamic variability, indicating less favorable outcomes. The results highlighted the critical role of precise anatomical compatibility, with larger valve sizes proving more effective in enlarged RVOT geometry. Valve sizes tailored to specific RVOT morphologies can enhance PPVI outcomes. Types 1 and 2 are ideal for PPVI, while Types 3 and 5 present challenges due to hemodynamic variability. This study supports 3D modeling and in vitro testing for pre-procedural planning to reduce complications, with future research exploring dynamic imaging and materials mimicking tissue properties.","PeriodicalId":19814,"journal":{"name":"Pediatric Cardiology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143374555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
