Prognostic value of left atrial reservoir function in patients with severe primary mitral regurgitation undergoing mitral valve repair.
Mitral regurgitation (MR) has a significant haemodynamic impact on the left atrium. Assessment of left atrial reservoir strain (LARS) may have important prognostic implications, incremental to left atrial (LA) volume, and conventional parameters of left ventricular (LV) structure and function.

N-Terminal Pro-B-Type Natriuretic Peptide in Risk Stratification of Heart Failure Patients With Implantable Cardioverter-Defibrillator.
The prognostic value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in heart failure (HF) is well-established. However, whether it could facilitate the risk stratification of HF patients with implantable cardioverter-defibrillator (ICD) is still unclear.</AbstractText>To determine the associations between bas...

Incidence and predictors of sudden cardiac death in arrhythmogenic right ventricular cardiomyopathy: a pooled analysis.
Arrhythmogenic right ventricular cardiomyopathy (ARVC), an inherited heart muscle abnormality, is a major cause of sudden cardiac death (SCD). However, the burden of SCD and risk factors in ARVC are not clearly described. Thus, we estimated the rates and predictors of SCD in ARVC in a meta-analysis.</AbstractText>PubMe...

Effects of Acute Triiodothyronine Treatment in Patients with Anterior Myocardial Infarction Undergoing Primary Angioplasty: Evidence from a Pilot Randomized Clinical Trial (ThyRepair Study).
<b><i>Background:</i></b> Thyroid hormone has a differential action on healthy and ischemic heart. Triiodothyronine (T3) administration improved postischemic cardiac function while it limited apoptosis in experimentally induced ischemia. Thus, the present study investigated the potential effects of acute liothyronine (...

Direct current cardioversion-triggered atypical Tako-tsubo cardiomyopathy: a case report and review of literature.
Tako-tsubo stress cardiomyopathy is a clinical syndrome marked by transient reduction of left ventricular function in the setting of emotional or physical stress and in the absence of obstructive coronary artery disease. We describe a case of an atypical variant of Tako-tsubo in a male patient following an elective dir...

Coronary-pulmonary artery fistula with lung hypoplasia and a bicuspid aortic valve: A case report.
With an incidence of less than 1%, a Coronary Artery to Pulmonary Artery fistula (CAPF) is a rare coronary anomaly that causes heart failure. It causes a left to right cardiac shunt. While guidelines favor surgical correction in symptomatic patients, we present a challenging case with multiple cardio-thoracic pathologi...

Influence of catheter ablation for atrial fibrillation on atrial and ventricular functional mitral regurgitation.
The purpose of this study was to compare the impact of catheter ablation on cardiac structural reverse remodelling and atrial (AFMR) and ventricular (VFMR) functional mitral regurgitation (MR), and the long-term prognosis of patients with AFMR and VFMR.</AbstractText>The retrospective study included persistent AF patie...

Dronedarone for the treatment of atrial fibrillation with concomitant heart failure with preserved and mildly reduced ejection fraction: a post-hoc analysis of the ATHENA trial.
Limited therapeutic options are available for the management of atrial fibrillation/flutter (AF/AFL) with concomitant heart failure (HF) with preserved (HFpEF) and mildly reduced ejection fraction (HFmrEF). Dronedarone reduces the risk of cardiovascular events in patients with AF, but sparse data are available examinin...

Vitamin C Improves the Outcomes of Cardiopulmonary Resuscitation and Alters Shedding of Syndecan-1 and p38/MAPK Phosphorylation in a Rat Model.
Background Post-resuscitation syndrome, involves a severe inflammatory response following successful cardiopulmonary resuscitation. The potential mechanism of Vitamin C (VitC) after cardiopulmonary resuscitation on myocardial and cerebral function, duration of survival is undefined. Methods and Results A first set of e...

Extracorporeal Cardiopulmonary Resuscitation Guided by End-Tidal Carbon Dioxide-a Porcine Model.
Extracorporeal membrane cardiopulmonary resuscitation (ECPR) during cardiopulmonary resuscitation (CPR) for selected cases and end-tidal carbon dioxide (ETCO<sub>2</sub>) could be used to guide initiation of ECPR. Ventricular fibrillation was induced in 12 pigs and CPR was performed until ETCO<sub>2</sub> fell below 10...

Circulating linoleic acid at the time of myocardial infarction and risk of primary ventricular fibrillation.
Primary ventricular fibrillation (PVF) is a major driver of cardiac arrest in the acute phase of ST-segment elevation myocardial infarction (STEMI). Enrichment of cardiomyocyte plasma membranes with dietary polyunsaturated fatty acids (PUFA) reduces vulnerability to PVF experimentally, but clinical data are scarce. PUF...

Predictors of Early and Late Atrioventricular Block Requiring Permanent Pacemaker Implantation After Transcatheter Aortic Valve Replacement: A Single-Center Experience.
Complete heart block requiring permanent pacemaker can occur early following transcatheter aortic valve replacement (TAVR) due to mechanical compression of the aortic valve annulus and associated atrio-ventricular (AV) conduction system. Data are limited regarding late PM implantation after TAVR. The purpose of this st...

Long-term consumption of artificial sweeteners does not affect cardiovascular health and survival in rats.
Recent epidemiological cohort studies have suggested that consumption of artificial sweeteners (AS) is associated with adverse cardiovascular events and mortality. However, these population association studies cannot establish a causal relationship. In this study we investigated the effect of long-term (1-year) consump...

Ventricular tachycardia incidence and erythrocyte membranes &#x3b2;-adrenoreactivity in patients with implanted cardioverter-defibrillator.
In patients with high risk of ventricular tachycardia (VT) the proven beneficial therapy is the implantable cardioverter defibrillator (ICD). It has been shown that the coronary artery disease (CAD) and VT development are accompanied by a persistent change of the sympathoadrenal system activity. This leads to a decreas...
