Rationale: Premature birth affects 10% of live births in the United States and is associated with alveolar simplification altered pulmonary microvascular development. However, little known about long-term impact prematurity has on vasculature.Objectives: Determine effects right ventricular vascular hemodynamics.Methods: Preterm subjects (n = 11) were recruited from Newborn Lung Project, a prospectively followed cohort at University Wisconsin-Madison, born preterm very low weight (≤1,500 g;...
To identify risk factors for late pulmonary artery hypertension (PH) at 36 weeks' postmenstrual age (PMA) in infants born before 28 gestation. A retrospective cohort study included < gestation who underwent PH screening echocardiography PMA. We compared characteristics between with and without to determine associations. Of 99 infants, 20 (20%) developed PH. The FiO2% requirement 4 weeks of age, home oxygen use, procedural patent ductus arteriosus closure were associated Bronchopulmonary...
Infective endocarditis in infants with congenital heart disease is exceedingly rare and thus, treatment guidelines expected outcomes are understudied. We present a 3-month-old girl diagnosed native tricuspid valve at the time of her pre-Glenn cardiac catheterization. She had resultant right ventricular dysfunction. After initiating intravenous antibiotics, she underwent an operation including bidirectional Glenn, Sano shunt extirpation, repair, central pulmonary artery stent insertion. At 9...
Objectives . To quantify radiation exposure during pediatric cardiac catheterizations performed by multiple operators on a new imaging platform, the Artis Q.zen (Siemens Healthcare, Forchheim, Germany), and to compare these data contemporary benchmark values. Background The has been shown achieve significant reduction select types of in small single-center studies. No large multicenter study exists quantifying patient dose for broad spectrum procedures. Methods Retrospective collection Air...
To determine the consequences of an early catheter-based intervention on pulmonary artery (PA) growth and right ventricular (RV) myocardial function in animal model branch PA stenosis.Acute results safety profiles deliberate stent fracture within vasculature have been demonstrated. The long-term impact is not understood.Implantation small diameter stents was performed a pig left stenosis at 6 weeks (10 kg) followed by dilations 10 (35 18 (65 with intent to implant large stents. Hemodynamics,...
Abstract Objectives Compare lung parenchymal and pulmonary artery (PA) growth hemodynamics following early delayed PA stent interventions for treatment of unilateral branch stenosis (PAS) in swine. Background How the circulation remodels response to different durations hypoperfusion how much function can be recovered with catheter directed at differing time periods development is not understood. Methods A total 18 swine were assigned four groups: Sham ( n = 4), untreated left PAS (LPAS)...
A patent foramen ovale (PFO) is linked to increased risk of decompression illness in divers. One theory that venous gas emboli crossing the PFO can be minimized by avoiding lifting, straining and Valsalva maneuvers. Alternatively, we hypothesized mild increases external inspiratory expiratory resistance, similar provided a SCUBA regulator, recruit PFO. Nine healthy adults with Valsalva-proven completed three randomized trials (inspiratory, expiratory, combined loading) six levels increasing...
Cardiac catheterization (cath) is essential to manage congenital heart disease (CHD), yet it carries risks. We found our institutional complication rate exceeded the mean for IMPACT Registry; most common being red blood cell transfusion (RBCT) within 72 hours. Thus, we implemented a quality improvement project reduce cath associated RBCT. Using PDSA methodology applied interventions including: 1. Intra-cath practices hemodilution, loss, and excessive anticoagulation, 2. Standardized...
Branch pulmonary artery (PA) stenosis (PAS) commonly occurs in patients with congenital heart disease (CHD). Prior studies have documented technical success and clinical outcomes of PA stent interventions for PAS but the impact on ventricular function is unknown. The objective this study was to utilize 4D flow cardiovascular magnetic resonance (CMR) better understand stenting contraction a swine model unilateral branch stenosis.
