Abstract Turner syndrome (TS) is a rare disorder affecting 25–50 in 100000 female newborns. Bicuspid aortic valve (BAV) is assumed to be the most common congenital heart defect (CHD) in TS. In literature, reported BAV prevalence in TS ranges between 14% and 34%. The specific BAV prevalence in TS is still unknown. The aim of this study was to give a more precise estimation of BAV prevalence in TS by conducting a meta-analysis of TS-studies, which detected BAV by either cardiac magnetic resonance imaging (MRI) or cardiac computed tomography (CT). We searched PubMed, Cochrane Library, and Web of Science databases to… More >

Abstract Pulmonary valve implant is frequently necessary in children and adults with congenital heart disease. Infective endocarditis represents a rare but life-threatening complication after transcatheter pulmonary valve implantation. There are various treatments for native or prosthetic valve endocarditis. Surgical intervention, combined with intravenous antibiotic treatment, is of paramount importance, in case of concomitant mediastinal infection, in order to ensure the radical debridement of all infected tissue, avoiding any recurrent endocarditis. In this report, we describe a rare case of mediastinitis, associated with an infected endocarditis, occurring 8 months after Melody (Medtronic^®, Minneapolis, USA) valve implant, successfully treated with the implantation of… More >

Abstract Objectives: Factors influencing results of balloon valvuloplasty (BVP) of pulmonary valve stenosis (PS) in children are investigated. Background: BVP has become the standard of care for PS, medium-term results are not uniform and depend on various preconditions. Methods: We analysed the medium-term results of BVP of PS in children in an observational, single centre study. Need for additional procedure was defined as outcome after initial BVP. Results: We included 143 children (83 female) at a median (IQR) age of 2.6 (0.26–9.24) months and body weight of 5 (3.4–8) kg at BVP with a follow–up of 5.04 (1.6–10.2) years. We used… More >

Abstract Cardiovascular computational fluid dynamics (CFD) based on patient-specific modeling is increasingly used to predict changes in hemodynamic parameters before or after surgery/interventional treatment for aortic dissection (AD). This study investigated the effects of flow boundary conditions (BCs) on patient-specific aortic hemodynamics. We compared the changes in hemodynamic parameters in a type A dissection model and normal aortic model under different BCs: inflow from the auxiliary and truncated structures at aortic valve, pressure control and Windkessel model outflow conditions, and steady and unsteady inflow conditions. The auxiliary entrance remarkably enhanced the physiological authenticity of numerical simulations of flow in the ascending… More >

Abstract Economic dispatch has a significant effect on optimal economical operation in the power systems in industrial revolution 4.0 in terms of considerable savings in revenue. Various non-linearity are added to make the fossil fuel-based power systems more practical. In order to achieve an accurate economical schedule, valve point loading effect, ramp rate constraints, and prohibited operating zones are being considered for realistic scenarios. In this paper, an improved, and modified version of conventional particle swarm optimization (PSO), called Oscillatory PSO (OPSO), is devised to provide a cheaper schedule with optimum cost. The conventional PSO is improved by deriving a mechanism… More >

Abstract A single coronary artery is a very rare condition, commonly associated with other congenital anomalies. It could be generally considered as neither benign nor malignant form of congenital coronary artery anomalies since its pathophysiological and clinical implications grossly depend on different anatomical patterns defined by the site of origin and distribution of the branches. By presenting the patient who underwent successful coronary artery bypass grafting and aortic valve replacement surgery in a presence of isolated single coronary artery, we intend to emphasize natural and procedural risks and distinguish casual from causal in this extremely rare clinical and surgical scenario.

Abstract Background: An isolated bicuspid aortic valve (BAV) is associated with structural and functional abnormalities of the aorta and the left ventricle (LV). Although ~50% of patients with aortic coarctation (CoA) have a BAV, less is known about its impact on LV function and aortic geometry and function in CoA patients. In this cardiovascular magnetic resonance imaging (CMR) study, we analysed markers of LV and aortic function as well as aortic geometry in a large cohort of CoA patients with a BAV and compared them with CoA patients with a tricuspid aortic valve (TAV). Methods: We included 48 patients with a… More >

Abstract Patients with complete transposition of the great arteries (TGA) treated by the Senning procedure have a higher risk of developing heart failure due to: a) additional work load of the systemic (morphologic right) ventricle (sRV), b) arrhythmias, mainly caused by surgical implications at the atria as well as c) worsening of systemic tricuspid regurgitation. We present a unique case of a female patient who developed all these complications, who was successfully treated and was able to carry out a twin pregnancy. This breakthrough approach was based on: 1. detecting reversibility potential of myocardial systolic dysfunction in a severe valvular lesion… More >

Abstract Objective: This study aims to evaluate the morphology and function of the aortic valve after transcatheter closure of ventricular septal defect (VSD) with aortic valve prolapse (AVP) abased on clinical and radiological outcomes. Methods: From January 2013 to November 2014, 164 consecutive patients (97 males, 59.1%) with VSD and AVP were treated by transcatheter closure. The patients were divided into the mild AVP group (n = 63), moderate AVP group (n = 89) and severe AVP group (n = 12). The clinical and radiological outcomes of these patients were analyzed retrospectively. Results: In total, 146 (89.0%) patients were successfully treated… More >

Abstract Background: The surgical outcomes of tetralogy of Fallot (TOF) have evolved dramatically and have resulted in lower mortality rate. Currently, the many cardiac centers have a trend to early single-stage complete repair more than a staged repair. However, the patients who have an early primary repair were required transannular patch augmentation of a pulmonary valve frequently. This effect has been developed a chronic pulmonary insufficiency may lead to right ventricular dilation, dysfunction. In this era, the aim of treatment of TOF is attempted to preserve pulmonary valve annulus for prevent right ventricular dysfunction in the future. The systemic to pulmonary… More >
