Aims: In patients with severe aortic stenosis (AS) and preserved left ventricular ejection fraction (LVEF), low flow (LF) is currently defined using Doppler-echocardiography by a stroke volume index (SVi)<35 mL/m2. However, the relationship between LF and outcome remains unclear as data on normal reference values defining LF are scarce, and previous studies did not explore the risk associated with other SVi cut-points. We analysed the relationship between LF and mortality in severe AS to establish prognostic LF values associated with mortality risk...

Aims: Long-term freedom from atrial fibrillation (AF) after catheter ablation (CA) and consequently the potential for stroke reduction remain unpredictable. Percutaneous left atrial appendage closure (LAAC) is an effective mechanical alternative to oral anticoagulation (OAC) for stroke prevention in AF patients. This study aims to evaluate long-term clinical results of combined CA and LAAC in one single procedure. Methods and results: Patients with non-valvular AF who underwent combined CA and LAAC procedure were included in the retrospective compilation of independent prospective general LAAC registries at the individual centres...

BACKGROUND: In general, women have lower risk for cardiovascular disease. We tested whether this sex-specific protection persists also in the presence of hypertensive left ventricular hypertrophy (LVH). METHODS: 12,329 women and men with hypertension and free from prevalent cardiovascular disease enrolled in the prospective Campania Salute Network registry were followed over a median of 4.1years. Subjects were grouped according to the absence or the presence of LVH identified by echocardiography using validated sex-specific cut-off values of LV mass index (>47g/m2...

BACKGROUND: Recent reports showing the favorable role of patent foramen ovale (PFO) closure in patients with cryptogenic stroke have raised the issue of selecting optimal candidates. OBJECTIVES: We evaluated whether the benefits of PFO closure can be determined based on the morphologic characteristics of the PFO, as evaluated by transesophageal echocardiography. METHODS: Patients with cryptogenic stroke and high-risk PFO were divided between a transcatheter PFO closure and a medication-only group...

OBJECTIVES: Haemodynamic monitoring during post arrest care is important to optimise treatment. We compared stroke volume measured by minimally-invasive monitoring devices with or without thermodilution calibration, and transthoracic echocardiography (TTE), and hypothesised that thermodilution calibration would give stroke volume index (SVI) more in agreement with TTE during targeted temperature management (TTM). DESIGN: Comatose out-of-hospital cardiac arrest survivors receiving TTM (33 °C for 24 hrs) underwent haemodynamic monitoring with arterial pulse contour analyses with (PiCCO2®) and without (FloTrac® /Vigileo® monitor® ) transpulmonary thermodilution calibration...

BACKGROUND: Fetal cardiovascular magnetic resonance (CMR) imaging may provide a valuable adjunct to fetal echocardiography in the evaluation of congenital cardiovascular pathologies. However, dynamic fetal CMR is difficult due to the lack of direct in-utero cardiac gating. The aim of this study was to investigate the effectiveness of a newly developed Doppler ultrasound (DUS) device in humans for fetal CMR gating. METHODS: Fifteen fetuses (gestational age 30-39 weeks) were examined using 1...

Transcatheter left atrial appendage occlusion is increasingly used for stroke prevention in atrial fibrillation. The technique has proven effective and safe in randomized trials and multiple observational studies. The procedure is challenging due to the complex anatomy of the left atrial appendage; accurate cardiac imaging is essential for procedural guidance. Transesophageal echocardiography is the gold standard, but cardiac computed tomography (CT) has gained increasing interest within recent years. Cardiac CT offers high-resolution imaging allowing for preprocedural anatomic evaluation and device sizing, but may also be useful for exclusion of left atrial appendage thrombus, and follow-up assessment of residual peri-device leaks...

OBJECTIVE: Blood flow across the mitral valve during early left ventricular (LV) filling produces a 3-dimensional rotational fluid body, known as a vortex ring, that enhances LV filling efficiency. Diastolic dysfunction is common in elderly patients, but the influence of advanced age on vortex formation is unknown. The authors tested the hypothesis that advanced age is associated with a reduction in LV filling efficiency quantified using vortex formation time (VFT) in octogenarians undergoing coronary artery bypass graft (CABG) surgery...

Patients with a Fontan circulation have impaired exercise capacity. Cardiac rehabilitation (CR) has shown promise in enhancing peak exercise parameters in this population, but an improvement in submaximal exercise has not been consistently demonstrated. We assessed the hypothesis that participation in CR will be associated with more efficient oxygen extraction and ventilation during submaximal exercise. In this prospective study, pediatric Fontans completed two 60 min CR sessions per week for 12 weeks. Cardiopulmonary exercise testing and stress echocardiography were performed at baseline and last CR session, and then compared with a paired sample t test...

INTRODUCTION: Newborns with congenital diaphragmatic hernia (CDH) have varying degrees of pulmonary hypoplasia and pulmonary hypertension (PH), and there is limited evidence that cardiac dysfunction is present. We sought to study early neonatal biventricular function and performance in these patients by reviewing early post-natal echocardiography (ECHO) measurements and comparing them to normal term newborns. METHODS: Retrospective case-control study reviewing clinical and ECHO data on term newborns with CDH and normal controls born between 2009 and 2016...

INTRODUCTION    The excess pressure-time integral (excessPTI) and the reservoir pressure-time integral (reservoirPTI) are new metrics derived from blood pressure (BP) waveform decomposition. These markers predict cardiovascular (CV) complications and are associated with target organ damage in treated hypertensive patients or subjects with chronic and acute heart failure. OBJECTIVES    Herein we investigated whether reservoirPTI or excessPTI predict future CV events (death, stroke, myocardial infarction) in subjects with acute coronary syndrome (ACS) and diminished ejection fraction (EF)...

OBJECTIVE: The intent of fluid bolus therapy (FBT) is to increase cardiac output and tissue perfusion, yet only 50% of septic children are fluid responsive. We evaluated respiratory variation of inferior vena cava (IVC) diameter as a predictor of fluid responsiveness. METHODS: A prospective observational study in the ED of The Royal Children's Hospital, Melbourne, Australia. Patients were spontaneously ventilating children treated with FBT for sepsis-induced acute circulatory failure...

Background. Aerococcus urinae is a rare causative pathogen of infective endocarditis that results in a high risk of embolic events. The mortality rate for A urinae endocarditis is high. Old age and underlying urologic conditions are the best-known risk factors for infection. Case Description. We report the clinical course of the disease in a 49-year-old man who presented symptoms of a urinary tract infection. A few days later, transthoracic echocardiography showed a conspicuous mitral valve with myxomatous alterations...

Circulatory failure following cardiac arrest (CA) requires catecholamine support and occasionally veno-arterial extracorporeal membrane oxygenation (vaECMO). VaECMO-generated blood flow is continuous and retrograde, increasing ventricular stroke work. Our aim was to assess the benefit of a device generating a pulsatile vaECMO flow synchronized with the heart rhythm lowering systolic vaECMO output on the left ventricular ejection fraction (LVEF) and pulmonary capillary pressure (Pcap) after CA. This experimental randomized study in pigs compared standard nonpulsatile vaECMO (control) with pulsatile synchronized vaECMO (study) group using a pulsatility-generating device...

BACKGROUND: Increase of exercise capacity (peak VO2 ) after cardiac rehabilitation improves outcome in patients with coronary artery disease (CAD). Systolic and diastolic function have been associated with peak VO2 , but their role towards improvement of exercise capacity remains unclear. It is unknown which exercise intensity has the most beneficial impact on left ventricular (LV) geometry and function in CAD patients without heart failure. METHODS: 200 stable CAD patients without heart failure were randomized to 3months of aerobic interval training (AIT) or aerobic continuous training (ACT)...

BACKGROUND: Recent studies suggest that the left-sided septal pouch (SP) may increase the risk of cryptogenic stroke and act as an arrhythmogenic substrate. The aim of this study was to compare two transesophageal echocardiography (TEE) projections of the interventricular septum: mid-esophageal bicaval and short-axis views toward evaluating their ability to detect SPs. MATERIALS AND METHODS: A total of 146 patients with both bicaval and short-axis TEE views were included in this study...

AIMS: Paravalvular leak(PVL) remains an important issue in TAVI. The Edwards Sapien3(S3) valve has reduced PVL but up to one-third of patients remain with mild leak. Our study aims to identify predictors of mild PVL after TAVI with S3 valve. METHODS AND RESULTS: From 10/2015 to 5/2017, 122 consecutive patients underwent S3 TAVI for symptomatic severe aortic stenosis. 33 patients with mild PVL on transthoracic echocardiography at 30-day follow-up were compared to 89 with none/trace PVL...
