The right ventricle, which faces systemic pressure due to congenital heart disease, often develops premature systolic dysfunction. Cardiac hormones might be useful to identify patients with such systolic dysfunction. This prospective study investigated the relationship of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) levels with right(More)
Neurogenic stunned myocardium (NSM) is a syndrome of cardiac stunning after a neurological insult. It is commonly observed after aneurysmal subarachnoid hemorrhage but is increasingly being reported after other neurological events. The underlying mechanism of NSM is believed to be a hypothalamic-mediated sympathetic surge causing weakened cardiac(More)
OBJECTIVE Retinopathy of prematurity (ROP) remains a leading cause of morbidity in the very low-birth-weight (VLBW) infant. This study investigates a possible association between serum/blood glucose and the development of ROP. METHODS A retrospective case-control study of all infants born between 1992 and 1997 at the Johns Hopkins Hospital with birth(More)
This study examined the effects of endovascular metallic implants on the ability of magnetic resonance imaging to evaluate cardiovascular anatomy and to assess ventricular size and function in 101 consecutive patients with Fontan palliation. Compared with studies in patients without implants, in whom 100% of anatomic segments were adequately visualized and(More)
Clinical imaging methods are highly effective in the diagnosis of vascular pathologies, but they do not currently provide enough detail to shed light on the cause or progression of such diseases, and would be hard pressed to foresee the outcome of surgical interventions. Greater detail of and prediction capabilities for vascular hemodynamics and arterial(More)
OBJECTIVES To describe a new technique for transcatheter patent ductus arteriosus (PDA) closure in extremely preterm infants using commercially available technology. BACKGROUND PDA in premature neonates continues to be a significant clinical problem contributing importantly to both morbidity and mortality. Surgical ligation and medical therapy both have(More)
BACKGROUND Transcatheter pulmonary valve replacement (tPVR) is an accepted therapy for treatment of dysfunctional right ventricular outflow tract (RVOT) conduits. At present, the majority of Fallot patients who undergo transannular patch (TAP) repair are not candidates for tPVR due to the large irregular nature of their RVOT. Herein, we describe a novel(More)
PURPOSE To characterize the range of biventricular size and function evaluated by steady-state free precession (SSFP) cine magnetic resonance (MR) in a large cohort of patients with repaired tetralogy of Fallot (TOF), and to compare these measurements in those with a right ventricular outflow tract (RVOT) patch vs. a right ventricle-to-pulmonary artery(More)
Preschoolers frequently require sedation for echocardiograms. This study compared various sedation drugs at the authors' institution, as well as the charges for moderate versus deep sedation. From 2001 to 2007, sedation was administered to 703 patients ages 2 to 4 years. Four drug regimens were used: chloral hydrate (CH), chloral hydrate with(More)
Congenital unilateral pulmonary venous atresia is a rare anatomical defect. Patients present with pulmonary symptoms, and diagnosis may be elusive. Pulmonary arterial wedge angiography is the gold standard with which to achieve diagnosis, and surgical intervention is often required for symptomatic patients.
