Abstract Background: Renovascular hypertension (RVH) can be caused by renal artery stenosis (RAS) and/ or middle aortic syndrome (MAS).
Methods: Patients who received surgical or transcatheter treatment for RVH between 1/1991 and 11/2017 were retrospectively reviewed using age = adjusted blood pressure ratio (BPR).
Results: Fifty-three patients diagnosed with RVH at a median age of 4.5 (0–18) years were included. Vascular involvement ranged from MAS with RAS (20), RAS only (32), and MAS only (1). The first intervention was transcatheter in 47 patients (transcatheter group: angioplasty = 41, stenting = 5, and thrombectomy = 1), and surgical in 6 patients (surgical… More >

Abstract Background: Up to 90% of individuals with Alagille syndrome have congenital heart diseases. Peripheral pulmonary artery stenosis (PPS), resulting in right ventricular hypertension and pulmonary flow disparity, is one of the most common abnormalities, yet the hemodynamic effects are illdefined, and optimal patient management and treatment strategies are not well established. The purpose of this pilot study is to use recently refined computational simulation in the setting of multiple surgical strategies, to examine the influence of pulmonary artery reconstruction on hemodynamics in this population.
Materials and Methods: Based on computed tomography angiography and cardiac catheterization data, preoperative pulmonary artery models… More >

Abstract Objective: We describe the long-term follow-up of a child with recurrent hemoptysis due to severe pulmonary vein stenosis decompressing via collaterals to esophageal varices.
Design: Case report
Setting: Tertiary children’s hospital
Patient: Single child through ages 2- to 11-year old
Interventions: The child underwent cutting balloon angioplasty, bare metal stenting, and implantation of a PTFE-covered stent, all of which failed rapidly. Only after placement of a paclitaxel drug eluting stent did he have prolonged relief from hemoptysis and long-term patency of the treated vein. The stents were serially dilated to keep up with somatic growth of the child, eventually culminating… More >

Abstract Objective: Evaluate long‐term outcomes following balloon pulmonary valvuloplasty (BPV) for pulmonary stenosis (PS).
Background: Long‐term data following BPV is limited to small, single center studies.
Methods: BPV from April 12, 1985 to January 7, 2015 from three centers were included. Outcomes studied were ≥ moderate PI by echocardiogram and residual PS ≥ 40 mm Hg. Risk factors for ≥ moderate PI, residual PS, and repeat intervention were assessed by univariate and multivariate analysis.
Results: Among 254 patients, mean age at BPV was 3.8 years (range 1 day‐67 years), initial PS catheter gradient was 56 mm Hg (IQR 40‐70), 19% had… More >

Abstract Objective: Cardiovascular lesions are the leading cause of morbidity and mortality in patients with Williams syndrome. Recent studies have rebutted conventional reports about the natural course of cardiovascular anomalies in Williams syndrome.
Design: Retrospective study.
Setting: Single tertiary center.
Patients: Eighty patients with Williams syndrome followed up for more than 5 years.
Interventions: Not applicable.
Outcome Measures: Long‐term outcome of cardiovascular lesions, peak velocity change in obstructive cardiovascular lesions over time, post‐interventional courses of disease‐specific intervention, and intervention‐free survival of obstructive cardio‐ vascular lesions.
Results: The median follow‐up duration was 11.0 (5.1‐28.3) years. Among 80 pa‐ tients, supravalvular aortic stenosis… More >

Abstract Objective: To evaluate the prevalence of Noonan spectrum disorders (NSD) in a pediatric population with valvar pulmonary stenosis (vPS) and identify the clinical characteristics that differentiate those with NSD from those without NSD.
Design: A retrospective chart review of 204 patients diagnosed with vPS between 9/1/2012 and 12/1/2016 at a pediatric medical center was performed. The quantitative features of vPS, genetic diagnosis information, and phenotypic characteristics of Noonan syndrome were collected. Chi‐square test, Fisher’s exact test, t test, Wilcoxon rank‐sum test, and ANOVA were used for comparisons among the groups. Logistic regression was used to test for the association between… More >

Abstract Objectives. There is a paucity of data about mixed aortic valve disease (MAVD) in patients with bicuspid/unicuspid aortic valve (BAV). This study sought to describe the outcomes of patients with moderate/severe MAVD.
Methods. We queried our database for patients with BAV and moderate/severe MAVD seen between 1994 and 2013. We excluded patients with baseline New York Heart Association (NYHA) III/IV symptoms, left ventricular ejection fraction <50%, aortic dimension >50 mm, and significant disease of other valves. The purpose of the study was to determine the freedom from NYHA III/IV symptoms and aortic valve replacement (AVR).
Results. We identified 138 patients… More >

Abstract Fractional flow reserve (FFR) computed from computed tomography angiography (CTA), i.e., FFR_CT has been used in the clinic as a noninvasive parameter for functional assessment of coronary artery stenosis. It has also been suggested to be used in the assessment of carotid artery stenosis. The wall thickness of the vessel is an important parameter when establishing a fluid-structure coupling model of carotid stenosis. This work studies the effect of the vessel wall thickness on hemodynamic parameters such as FFR_CT in carotid stenosis. Models of carotid stenosis are established based on CTA image data using computer-aided design software. It is assumed… More >

Abstract Pulmonary valve stenosis (PVS) is one common post-operative problem in patients with tetralogy of Fallot (TOF) after repair. Congenital bicuspid pulmonary valve (BPV) is a condition of valvular stenosis, and the occurrence of congenital BPV is often associated with TOF. Compared with the biomechanical simulation model of the bicuspid aortic valve, the BPV is often neglected. In this study, we developed a dynamic biomechanical model of a simulated normal pulmonary root (PR) with tri-leaflet and a model of simulated PR with BPV in patients with repaired TOF in order to describe the effect of geometric structure with BPV on the… More >
