INTRODUCTION    Restoring sinus rhythm in patients with atrial fibrillation (AF)/atrial flutter (AF) requires adequate oral anticoagulation (OAC) prior to direct current cardioversion (DCC). Some patients eligible for DCC are not properly anticoagulated. OBJECTIVES    Assessment of risk factors for thrombus and spontaneous echo contrast (SEC) in the left atrium (LA) as well as the safety profile of DCC under transesophageal echocardiography control (TEE) in patients with inadequate anticoagulation. PATIENTS AND METHODS    From the cohort of 316 patients admitted for DCC, 139 (age 63...

Catheter ablation of ventricular tachycardia (VT) is an established therapy for patients with ischemic cardiomyopathy to reduce implantable cardioverter-defibrillator (ICD) interventions and is a class I recommendation in international guidelines. Numerous publications confirm its value. Use of three-dimensional mapping systems with or without image integration is standard for ablation of complex arrhythmias. In patients with history of myocardial infarction they help to understand activation of reentrant circuits and are prerequisite for substrate mapping...

The difference between men and women is clear even just by looking at an electrocardiogram: females present higher resting heart rate, a shorter QRS complex length and greater corrected QT interval. The development of these differences from pubertal age onward suggests that sexual hormones play a key role, although their effect is far from being completely understood. Different incidences between sexes have been reported for many arrhythmias, both ventricular and supraventricular, and also for sudden cardiac death...

Pharmacologic challenge with sodium channel blockers is part of the diagnostic workout in patients with suspected Brugada syndrome. The test is overall considered safe but both ajmaline and flecainide detain well known pro-arrhythmic properties. Moreover, the treatment of patients with life-threatening arrhythmias during these diagnostic procedures is not well defined. Current consensus guidelines suggest to adopt cautious protocols interrupting the sodium channel blockers as soon as any ECG alteration appears...

OBJECTIVES: Guidelines recommend a 0h/1h high-sensitivity cardiac troponin T (hs-cTnT) diagnostic strategy in acute chest pain patients. There is however little data on the performance of this strategy when combined with clinical risk stratification. We aimed to evaluate the diagnostic accuracy of an accelerated diagnostic protocol (ADP) using the 0h/1h hs-cTnT strategy together with an adapted Thrombolysis In Myocardial Infarction (TIMI) score and ECG for ruling out major adverse cardiac events (MACE) within 30 days...

For patients with stable coronary artery disease (SCAD), either after hospitalization for acute cardiac events or in the chronic phase, comprehensive treatment programs should be devoted to: (i) reducing mortality and major adverse cardiovascular events, (ii) reducing the ischemic burden and related symptoms, and (iii) increasing exercise capacity and quality of life.Heart rate (HR) has demonstrated to have prognostic value and patients beyond the limit of 70 bpm display increased risk of all the above adverse outcomes, even after adjustment for parameters such as the extension of myocardial infarction and the presence of heart failure...

MicroRNAs (miRNAs) are a huge class of noncoding RNAs that regulate protein-encoding genes (degradation/inhibition of translation). miRNAs are nowadays recognized as regulators of biological processes underneath cardiovascular disorders including hypertrophy, ischemia, arrhythmias, and valvular disease. In particular, circulating miRNAs are promising biomarkers of pathology. This review gives an overview of studies in aortic valve stenosis (AS), exclusively considering myocardial remodeling processes. We searched through literature (till September 2016), all studies and reviews involving miRNAs and AS (myocardial compartment)...

BACKGROUND: Guidelines suggest that an abnormal blood potassium level is a relative contraindication to performing dobutamine stress echocardiography (DSE). However, this has not been previously studied. METHODS: We reviewed a consecutive series of patients who had potassium testing within 48 hours of undergoing DSE for the evaluation of myocardial ischemia over a 10-year period (N = 13,198). Normal potassium range in our laboratory is 3.6-5.2 mmol/L. Hemolyzed samples were not included...

Nurses and allied professionals are at the forefront of care delivery in patients with arrythmogenic risk and have a responsibility to deliver care that is focused on their individual needs. The 2015 European Society of Cardiology guideline on prevention of ventricular arrhythmia and sudden cardiac death heralds a step-change in patient and family focus and interdisciplinary involvement. This development reflects a recognition within the European Society of Cardiology that chronic care of patients with cardiovascular conditions can be improved by involving all stakeholders, making use of multidisciplinary interventions, and placing the patient at the centre of the care process...

At this time, we find ourselves with an abundance of guidelines for management of patients with manifest ventricular tachyarrhythmias, or at risk for such arrhythmias, in patients with coronary heart disease (CHD). The guidelines are focused primarily on the "appropriate use" of the implantable cardioverter/defibrillator (ICD). Unfortunately, the bulk of the guidelines have very little basis in the underlying pathophysiology responsible for sudden cardiac death (SCD) in patients with CHD. Rather, they are based primarily on the results of randomized clinical trials that merely sought to take broad populations at elevated total mortality risk and determining whether the ICD can reduce overall mortality...

Automatic detection and transvenous or subcutaneous defibrillation of malignant ventricular arrhythmias by implantable cardioverter defibrillators are vital for management of patients at high risk for sudden cardiac death. Guidelines and appropriate use criteria based on data from several clinical trials support prophylactic defibrillator implantation in patients with symptoms of heart failure and left ventricular ejection fraction ≤35%. Yet, existing guidelines direct defibrillator implantation to a small subset of the overall population at risk for sudden death, and with an average annual appropriate shock rate of 5...

Aims: The latest 2015 ESC Guidelines on the prevention of sudden cardiac death make a Class IIa recommendation for ICD implantation in patients listed for heart transplantation. This recommendation was based on expert consensus in view of the sparsity of data. Methods and results: All patients listed for heart transplantation at the University Hospitals of Leuven from 2002 until 2014 were studied retrospectively. Exclusion criteria were age <16 years, cardiac disease other than ischaemic or dilated cardiomyopathy and re-transplantation...

Aims: Sarcoidosis with cardiac involvement is a rare pathological condition, and therefore cardiac resynchronization therapy (CRT) for patients with cardiac sarcoidosis is even further rare. We aimed to clarify the clinical features of patients with cardiac sarcoidosis who received CRT. Methods and results: We retrospectively reviewed the clinical data on CRT at three cardiovascular centres to detect cardiac sarcoidosis patients. We identified 18 (8.9%) patients with cardiac sarcoidosis who met the inclusion criteria out of 202 with systolic heart failure who received CRT based on the guidelines...

This review article provides an outline of 5 of the updated clinical practice guidelines of the European Society of Cardiology developed by leading experts of the relevant working groups of the society. Guidelines deal with new approaches to identification, diagnosis, treatment and prevention of pericardial diseases, ventricular arrhythmias, pulmonary hypertension, infective endocarditis and acute coronary syndrome without ST segment elevation and comprise new diagnostic algorithms. Risk stratification and taking into account etiological factors are considered as important links for conduct of medical and surgical treatments of corresponding cardiovascular diseases...

Extracorporeal life support (ECLS) is a very effective bridging therapy in patients with refractory ventricular tachycardia (VT) associated with cardiogenic shock. A moribund patient in extremis, is not amenable to optimization by standard ACC/AHA guidelines. New approaches and novel salvage techniques are necessary to improve outcomes in patients with refractory clinical settings such as malignant ventricular arrhythmias, cardiac arrest, cardiogenic shock and/or pulmonary failure until further management options are explored...

Sex-specific differences in the epidemiology, pathophysiology, clinical presentation, clinical treatment, and clinical outcomes of atrial fibrillation (AF), sustained ventricular arrhythmias, and sudden cardiac death are recognized. Sex hormones cause differences in cardiac electrophysiological parameters between men and women that may affect the risk for arrhythmias. The incidence and prevalence of AF is lower in women than in men. However, because women live longer and AF prevalence increases with age, the absolute number of women with AF exceeds that of men...

BACKGROUND: The majority of sudden cardiac death (SCD) in patients with heart failure occurs in those with mild-moderate left ventricular (LV) systolic dysfunction (LVEF 36-50%) who under current guidelines are ineligible for primary prevention implantable cardiac defibrillator (ICD) therapy. Recent data suggest that cardiac magnetic resonance (CMR) evidence of replacement fibrosis forms a substrate for malignant arrhythmia and therefore potentially identifies a subgroup at increased risk of SCD...

Left ventricular hypertrophy, diastolic dysfunction and fibrosis are main features of hypertrophic cardiomyopathy (HCM). Guidelines recommend β-adrenoceptor or Ca(2+) channel antagonists as pharmacological treatment. The Ca(2+) channel blocker diltiazem recently showed promising beneficial effects in pre-clinical HCM, particularly in patients carrying MYBPC3 mutations. In the present study we evaluated whether diltiazem could ameliorate or reverse the disease phenotype in cells and in vivo in Mybpc3-targeted knock-in (KI) mouse model of HCM...
