Late development of annuloaortic ectasia (AAE) and progression of aortic regurgitation (AR) are widely recognized outcomes following an arterial switch operation (ASO). We treated a 29-year-old male with AAE and rapid aortic root expansion, who underwent ASO as a neonate and aortic valve replacement (AVR) as an adult. He was diagnosed as having dextro-(D-loop) transposition of the great arteries after birth and underwent ASO at the age of 13 months. At the age of 19 years, AVR was performed for progressive AR...

To explore the clinical and genetic characteristics of Williams-Beuren syndrome (WBS) and to raise awareness of the disease. The characteristics of clinical manifestations, personal history, cardiac ultrasound, brain magnetic resonance imaging (MRI), electroencephalogram (EEG) and chromosome detection results of two cases with WBS were analyzed. The two patients were both male and the age was 11 months and 1 day, and 9 months and 9 days, respectively. They both suffered from cardiovascular malformation: case one presented supravalvular aortic stenosis, and case two showed atrial septal defect and patent ductus arteriosus...

BACKGROUND/AIMS: Previous studies have demonstrated that leonurine, a unique alkaloid compound of Herba leonuri, can exert anti-oxidative and anti-inflammatory effects on the development of atherosclerosis (AS). This study was designed to investigate the effects of leonurine on cholesterol efflux from THP-1 macrophage-derived foam cells and development of atherosclerotic lesions in apoE-/- mice, and further determine the potential mechanisms. METHODS: Human THP-1 cells were fully differentiated into foam cells by the pre-treatment with phorbol-12-myristate-13-acetate (PMA) and oxidized density lipoproteins (ox-LDL)...

BACKGROUND: The diagnostic assessment of fetal arrhythmias relies on the measurements of atrioventricular (AV) and ventriculoatrial (VA) time intervals. Pulsed Doppler over in- and outflow of the left ventricle and tissue Doppler imaging are well-described methods, while Doppler measurements between the left brachiocephalic vein and the aortic arch are less investigated. The aim of this study was to compare these methods of measurement, to find influencing factors on AV and VA times and their ratio, and to create reference ranges...

Aims: To support decision-making regarding prosthetic valve selection in non-elderly adults, we aim to provide a detailed overview of outcome after contemporary mechanical aortic valve replacement (AVR). Methods and results: A systematic review was conducted for papers reporting clinical outcome after AVR with bileaflet mechanical valves with a mean patient age ≥18 and ≤55 years, published between 1 January 1995 and 31 December 2015. Through meta-analysis outcomes were pooled and entered into a microsimulation model to calculate (event-free) life expectancy and lifetime event risk...

Aims: This European Association Cardiovascular Imaging (EACVI) Expert Consensus document aims at defining the main quantitative information on cardiac structure and function that needs to be included in standard echocardiographic report following recent ASE/EACVI chamber quantification, diastolic function, and heart valve disease recommendations. The document focuses on general reporting and specific pathological conditions such as heart failure, coronary artery and valvular heart disease, cardiomyopathies, and systemic diseases...

: Many factors could increase the risk of stroke after transcatheter prosthetic aortic valve implant, mainly related to the procedure itself, or to the type of valvular prosthesis, or to the presence of atrial fibrillation. There is a wide variability in the antithrombotic treatment utilized in clinical practice, as far as the choice of drugs (anticoagulant, single or dual antiplatelet treatment), and its optimal duration. The most popular therapeutic strategy, also recommended by the Scientific Societies, is dual antiplatelet (aspirin and clopidogrel) for the first 3-6 months then switching to single antiplatelet (usually aspirin), limiting oral anticoagulant therapy only to those patients with other primary indication to the treatment...

Due to improved survival and clinical outcomes, congenital heart disease is an area of growing importance within the medical community. As these patients reach adulthood and have children, there has been a growing appreciation for the increased risk of CHD among their offspring, strongly implying a genetic element. Given the growing wealth of genetic data available and these clinical implications, this review serves to re-examine the role of genetics within CHD, using Tetralogy of Fallot as a model pathology...

The hemodynamic performance of artificial aortic valves (AVs) and the probability for structural valve deterioration can be linked to the valve kinematics. Comparability among different studies is limited because of variations in the experimental setups and physiologic boundary conditions. This study presents results of kinematic measurements of bioprosthetic and mechanical AVs that were tested in an identical experimental setting such that they can be directly compared with each other. The kinematics of AVs is typically presented in the form of the geometric orifice area and its temporal evolution...

Although improvement in cardiac output and hemodynamic parameters is routinely demonstrated in patients implanted with continuous-flow left ventricular assist devices (CF-LVADs), improvement in exercise capacity is inconsistently seen. Our purpose was to determine whether native cardiac factors, LVAD factors, or comorbid factors were associated with lack of improvement. Review of all patients undergoing preimplant cardiopulmonary exercise testing (CPET) and CPET on LVAD therapy at one institution was performed between 2007 and 2014 (n = 49)...

BACKGROUND: Despite the paucity of data available, orally administered angiotensin-converting enzyme (ACE) inhibitors are empirically used in horses with valvular regurgitation. OBJECTIVE: Evaluate the echocardiographic and hormonal changes in response to oral benazepril in horses with left-sided valvular regurgitation. STUDY DESIGN: Prospective, randomised double-blind, placebo-controlled trial. METHODS: Horses with mitral valve (MR) and/or aortic valve regurgitation (AR) received oral benazepril (n = 6) at a dosage of 1 mg/kg q 12h or a placebo (n = 5) for 28 days...

BACKGROUND: The role of atherosclerosis in the pathogenesis of abdominal aortic aneurysm (AAA) is controversial. Atherosclerosis-associated peripheral artery disease (PAD) has been reported to be a risk factor for AAA in population screening studies; its relationship with AAA growth is controversial. METHODS: A systematic search of MEDLINE, Scopus, CINAHL and the Cochrane Central Register of Controlled Trials was conducted in April 2016 and repeated in January 2017...

Aims: Recent studies have reported non-inferior outcomes for transcatheter aortic valve implantation (TAVI) compared with surgical aortic valve replacement (SAVR) in intermediate-risk patients. However, a comparison of outcomes among TAVI patients depending upon the surgical risk score has not been performed in a large study. Our aim was to compare the outcomes of TAVI in low-, intermediate-, and high-risk patients, to ascertain if the morbidity and mortality is related to the patient's risk profile or the procedure itself...

Acute aortic regurgitation (AAR) due to infective endocarditis (IE) is a serious disease and usually requires surgical treatment. Our study aims to compare the clinical, echocardiographic, and microbiological characteristics as well as in-hospital outcome of patients with AAR according to the severity of heart failure (HF) and to evaluate predictors of in-hospital mortality in a tertiary centre. In a prospective analysis, we compared patients with NYHA functional class I-II HF (G1) vs. functional class III-IV HF (G2)...

Achromobacter xylosoxidans is a Gram-negative aerobic bacterium first described by Yabuuchi and Ohyama in 1971. A. xylosoxidans is frequently found in aquatic environments. Abdominal, urinary tract, ocular, pneumonia, meningitis, and osteomyelitis are the most common infections. Infective endocarditis is rare. As far as we know, until now, only 19 cases have been described, including this current report. We report the case of community-acquired native valve endocarditis caused by A. xylosoxidans in an elderly patient without a concomitant diagnosis of a malignancy or any known immunodeficiency...
