OBJECTIVES: Right ventricular (RV) failure complicating left ventricular assist device implantation is associated with increased mortality. Despite a lack of supporting evidence, venoarterial extracorporeal membrane oxygenation (ECMO) support is increasingly being used as an alternative to traditional temporary RV support. We report our institutional experience with ECMO-facilitated RV support after left ventricular assist device implantation. METHODS: We retrospectively reviewed the concept of temporary ECMO support for perioperative RV failure in 32 consecutive left ventricular assist device (mean age 52 ± 14 years; male 84...

OBJECTIVES: To evaluate the image quality and radiation dose of submillisievert standard-pitch CT pulmonary angiography (CTPA) with ultra-low dose contrast media administration in comparison to standard CTPA. MATERIALS AND METHODS: Hundred patients (56 females, 44 males, mean age 69.6±15.4 years; median BMI: 26.6, IQR: 5.9) with suspected pulmonary embolism were examined with two different protocols (n = 50 each, group A: 80 kVp, ref. mAs 115, 25 ml of contrast medium; group B: 100 kVp, ref...

Extreme prematurity is the leading cause of death among children under 5 years of age. Currently, there is no treatment for bronchopulmonary dysplasia (BPD), the most common complication of extreme prematurity. Experimental studies in animal models of BPD suggest that mesenchymal stromal cells (MSCs) are lung protective. To date, no systematic review and meta-analysis has evaluated the preclinical evidence of this promising therapy. Our protocol was registered with Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies prior to searching MEDLINE (1946 to June 1, 2015), Embase (1947 to 2015 Week 22), Pubmed, Web of Science, and conference proceedings (1990 to present) for controlled comparative studies of neonatal animal models that received MSCs or cell free MSC-derived conditioned media (MSC-CM)...

BACKGROUND: Gas6 signals through the TAM (TYRO-3, AXL, MERTK) receptor family mediating platelet activation and thrombus formation via activation of the aggregate-stabilizing αIIb β3 integrin. OBJECTIVE: Here we describe anti-thrombotic effects mediated by UNC2025, a small molecule MERTK tyrosine kinase inhibitor. METHODS: MERTK phosphorylation and downstream signaling were assessed by immunoblot. Light transmission aggregometry, flow cytometry, and microfluidic analysis were used to evaluate the impact of MERTK inhibition on platelet activation and stability of aggregate formation in vitro...

miR-200c is an antioncogene in multiple tumors. However, its function in the pathogenesis of pulmonary arterial hypertension (PAH) has not been thoroughly investigated nor understood. In this study, we discovered that miR-200c was able to substantially upregulate in pulmonary arterial smooth muscle cells (PASMCs) treated with endothelin-1 (ET-1). miR-200c also induced cell proliferation and suppressed cell apoptosis in PASMCs in vitro. However, miR-200c had no effect on G1/S/G2 transitions during the cell cycle...

Among 241 children with univentricular circulation who underwent total cavopulmonary connection (Glenn or Fontan) over a 17 years period (January 2000-April 2017), we found two patients who had diffuse coronary fistulisation of their myocardium (0.8%). We also report an additional third case from Oak Lawn, Illinois, USA. One of the children had documented normal coronary arteries and myocardium at catheterisation prior to development of the fistulisation process. The same child also developed extensive veno-venous collaterals...

We sought to compare pulmonary flow hemodynamic indices obtained by Fick and thermodilution catheterization techniques with phase-contrast MRI (PC-MRI) in children with diverse etiologies of pulmonary arterial hypertension (PAH). Calculation of pulmonary flow ([Formula: see text]) using the Fick principle in most catheter laboratories relies on an estimate of oxygen consumption which may limit its reliability. Flow hemodynamic indices acquired from thirty patients with PAH who underwent successful same-day PC-MRI and catheterization were evaluated for absolute and percent bias...

To explore the accuracy of main pulmonary artery (MPA) and ascending aorta (AAO) image evaluation in pediatric patients with single ventricle (SV) by comparing dual-source computed tomography (DSCT) with echocardiography. Thirty-one children with SV were retrospectively enrolled. The stenosis, dilation, and location of MPA and AAO were independently evaluated by DSCT and echocardiography. The accompanying arterial malformations were also assessed by DSCT. For 17 patients undergoing cardiac catheterization, the DSCT-based diameters of MPA and AAO were correlated with their pressures as measured by catheterization...

Background -Infants with ductal-dependent pulmonary blood flow may undergo palliation with either a patent ductus arteriosus (PDA) stent or modified Blalock-Taussig (BT) shunt. A balanced multi-center comparison of these two approaches is lacking. Methods -Infants with ductal-dependent pulmonary blood flow, palliated with either PDA stent or BT shunt from 1/08 to 11/15, were reviewed from the four member centers of the Congenital Catheterization Research Collaborative. Outcomes were compared using propensity score adjustment to account for baseline differences between groups...

In this article, we present results of the study of blebbing activity of membranes of peripheral blood lymphocytes, concentrations of soluble platelet/endothelial cell adhesion molecule 1, and vascular endothelial growth factor (VEGF) in patients with pulmonary arterial hypertension associated with congenital heart diseases. The research has shown that hypoxia and hemodynamic factors are the initiators of blebbing of membrane of peripheral blood lymphocytes. The activity of blebbing increases in parallel with the severity of the disease...

The paper considers a clinical example of current therapy for idiopathic pulmonary arterial hypertension in a female patient with its clinical deterioration. It shows the tactics of switching from one drug (bosentan) to others (macitentan) within in the same pathogenetic therapy group (endothelin receptor antagonists). The latest pulmonary hypertension classification (Nice, 2013) is presented. The current strategies of pathogenetic therapy for pulmonary hypertension are discussed.

AIM: To investigate left ventricular (LV) deformation properties, rotation, and twist during a bicycle ergometer exercise test among patients with idiopathic left bundle branch block (LBBB). SUBJECTS AND METHODS: Thirty-four patients with idiopathic LBBB having a mean QRS duration of 153±24 msec were examined. A control group included 18 apparently healthy volunteers. All the patients and apparently healthy individuals underwent echocardiography to determine LV hemodynamic parameters, deformity, rotation and twist at rest and after exercise test...

OBJECTIVE: The aim of the present study was to assess the technical feasibility and safety of the unilateral pulmonary artery occlusion (UPAO) test in preoperative evaluation of pneumonectomy or pleuropneumonectomy for lung or pleural tumours. MATERIALS AND METHODS: The UPAO test was performed on 91 patients who were scheduled to undergo or were being considered for pneumonectomy or pleuropneumonectomy between June 2003 and July 2016. There were 74 males and 17 females, with a median age of 65 years (range, 23-80)...
