Endothelin-1 (ET1) is dysregulated in pulmonary hypertension (PH). It may be important the pathobiology of congenital diaphragmatic hernia (CDH).We hypothesized that ET1 levels first month would higher infants with CDH who subsequently expired or were discharged on oxygen (poor outcome). We further associated concurrent severity PH.We sampled plasma at 24 to 48 hours, and 1, 2, 4 weeks age 40 prospectively enrolled newborns CDH. performed echocardiograms estimate artery pressure less than...
Objective This prospective study of pregnant patients, S urveillance To P revent AV B lock L ikely to O ccur Q uickly (STOP BLOQ), addresses the impact anti‐SSA/Ro titers and utility ambulatory monitoring in detection fetal second‐degree atrioventricular block (AVB). Methods Women with autoantibodies by commercial testing were stratified into high low anti–52‐kD and/or 60‐kD SSA/Ro applying at‐risk thresholds defined previous evaluation AVB pregnancies. The high‐titer group performed heart...
Pulmonary vascular disease and resultant pulmonary hypertension (PH) have been increasingly recognized in the preterm population, particularly among patients with bronchopulmonary dysplasia (BPD). Limited data exist on impact of PH severity right ventricular (RV) dysfunction at diagnosis outcome. The purpose this study was to evaluate if echocardiography measures cardiac BPD‐PH were associated mortality. is a retrospective analysis three months or less from time diagnosis. Survival using...
Background Tetralogy of Fallot with absent pulmonary valve is associated high mortality, but it remains difficult to predict outcomes prenatally. We aimed identify risk factors for mortality in a large multicenter cohort. Methods and Results Fetal echocardiograms clinical data from 19 centers over 10-year period were collected. Primary outcome measures included fetal demise overall mortality. Of 100 fetuses, pregnancy termination/postnatal nonintervention was elected 22. 78 intention treat,...
Fetal echocardiography is widely available, but normative data are not robust. In this pilot study, the authors evaluated (1) feasibility of prespecified measurements in a normal fetal echocardiogram to inform study design and (2) measurement variability assign thresholds clinical significance guide analyses larger echocardiographic Z score initiatives.Images from predefined gestational age groups (16-20, >20-24, >24-28, >28-32 weeks) were retrospectively analyzed. expert raters attended...
Currently, there are no established echocardiographic or hemodynamic predictors of mortality after weaning venoarterial extracorporeal membrane oxygenation in children. We wished to determine which measurements predict mortality.Over 3 years, we prospectively assessed six echo and variables at 3-5 circuit rates while flow. Hemodynamic were heart rate, inotropic score, arteriovenous oxygen difference, pulse pressure, index, lactate. Echo included shortening/ejection fraction, outflow tract...
Objective: To assess the utility and reliability of echocardiographic assessment hemidiaphragm motion abnormalities in pediatric cardiothoracic patients. Design: Retrospective observational study, with post hoc blinded fluoroscopic results. Setting: Tertiary care center. Patients: Thirty-six consecutive patients suspected paralysis were identified included study. Interventions: None. Measurements Main Results: The results both studies on all included. In addition, review study performed....
