BACKGROUND: A proportion of patients who receive cardiac resynchronization therapy (CRT) with defibrillator (CRT-D) live to receive a second generator. Controversy exists on whether an implantable cardioverter-defibrillator (ICD) should be offered to patients who have normalized or near normalized left ventricular ejection fraction (LVEF) at the time of generator replacement (GR). OBJECTIVE: To evaluate incidence of appropriate ICD therapy after CRT-D GR. METHODS: This series involved 1,026 consecutive patients who underwent CRT-D implant between January 2002 and December 2012...

The current regulatory guidelines recommend the use of QT interval to assess the risk of arrhythmogenic potential of new chemical entities. Recently, the electromechanical window (EMW), the difference in duration between electrical and mechanical systole, has been proposed as markers for drug-induced torsades de pointes (TdP); however, data of EMW in short QT model are not available. This study aimed to characterize the EMW as a marker for drug-induced ventricular arrhythmias in anesthetized rabbit model of long QT syndrome type 2 (LQT2) and short QT syndrome (SQTS) infused with reference compounds known to lengthen or shorten QT intervals...

BACKGROUND: Published studies state that adherence to regular laboratory assessments for anti-arrhythmic drugs is as low as 20%. Monitoring adherence is important as other studies have shown that up to 93% of patients on amiodarone experience an adverse drug event leading to a potentially lethal event. OBJECTIVE: To determine whether patients prescribed amiodarone or dofetilide are being monitored according to package labeling and guideline recommendations for adverse events...

BACKGROUND: The main causes of mortality in patients with chronic heart failure include sudden cardiac death (SCD) and progressive heart failure. Autonomic dysfunction plays a detrimental role in the progression of chronic heart failure. Left cardiac sympathetic denervation (LCSD) is an inexpensive and safe procedure which modifies autonomic innervation of the heart and is associated with a significant antifibrillatory effect. Whether LCSD reduces the risk of SCD, delays progression of heart failure and improves quality of life in patients with heart failure with reduced ejection fraction (HFrEF) is not known...

BACKGROUND: Catheter ablation (CA) therapy is the first choice treatment in adults with heart rhythm disturbances. The arrhythmias in adults are mainly conditioned by coronary disease. Etiology of arrhythmias in children is mostly associated with inherited heart disorders. According to the current guidelines the CA is widely used in children, indicating the need to make it more achievable in pediatric population. AIM: To assess efficacy and safety of CA in children with different types of arrhythmias on the initial learning curve at newly built Ablation Center in The Independent Pediatric Hospital of Medical University of Warsaw...

INTRODUCTION    Restoring sinus rhythm in patients with atrial fibrillation (AF)/atrial flutter (AFl) requires adequate oral anticoagulation prior to direct current cardioversion (DCC). Some patients eligible for DCC are not properly anticoagulated. OBJECTIVES    The aim of the study was to assess risk factors for thrombus and spontaneous echo contrast (SEC) in the left atrium (LA) as well as the safety profile of transesophageal echocardiography (TEE)-guided DCC in patients with inadequate anticoagulation...

In healthy mammalian hearts the action potential (AP) waveform initiates and modulates each contraction, or heartbeat. As a result, action potential height and duration are key physiological variables. In addition, rate-dependent changes in ventricular action potential duration (APD), and variations in APD at a fixed heart rate, are both reliable biomarkers of electrophysiological stability. Present guidelines for the likelihood that candidate drugs will increase arrhythmias rely on small changes in APD and Q-T intervals as criteria for Safety Pharmacology decisions...

Ventricular arrhythmias are an important cause of cardiovascular morbidity and mortality, particularly in those with structural heart disease, inherited cardiomyopathies, and channelopathies. The goals of ventricular arrhythmia management include symptom relief, improving quality of life, reducing implantable cardioverter defibrillator shocks, preventing deterioration of left ventricular function, reducing risk of arrhythmic death, and potentially improving overall survival. Guideline-directed medical therapy and implantable cardioverter defibrillator implantation remain the mainstay of therapy to prevent sudden cardiac death in patients with ventricular arrhythmias in the setting of structural heart disease...

Although transcatheter arrhythmia ablation (TCA) has been performed in children for over two decades, guidelines for routine use of post-ablation transthoracic echocardiography (TTE) are absent. We sought to determine the efficacy of TTE after apparently uneventful TCA procedures in detecting adverse findings and identify predisposing factors. A retrospective review of clinical and procedural data on patients who underwent TCA for supraventricular arrhythmias from 2000 to 2015 was performed. Pre- and post-ablation TTE data were reviewed...

Chronic Chagas cardiomyopathy (CCC) is a late complication of Chagas disease with various manifestations including arrhythmia, heart failure, thromboembolism, and stroke. In a patient with symptoms of heart failure and left ventricular apical aneurysm unexplained by structural heart or coronary vascular abnormalities, CCC should be strongly considered and inquiry made about exposure status. Typical electrocardiographic findings of bundle branch block, complete heart blocks, and ventricular arrhythmia are helpful clues...

We report a case of successful intravenous thrombolysis for a distal middle cerebral artery occlusion shortly after traumatic cardiopulmonary resuscitation due to an episode of ventricular tachycardia. A high prevalence of fatal cardiac arrhythmias in acute stroke patients raises the question of safety when administrating thrombolytic therapy after traumatic cardiopulmonary resuscitation; guidelines do not provide a satisfactory statement about this. Our case suggests that intravenous tissue-type plasminogen activator for acute ischemic stroke can be administered after a thorough risk-to-benefit evaluation without major adverse effects in patients after traumatic cardiopulmonary resuscitation, as bleeding complications seem rare and can be monitored and treated...

OBJECTIVE: Cardiac involvement in sarcoidosis can present in various ways, with atrioventricular (AV) block and ventricular arrhythmias being the most common signs. Because of initial non-specific findings, diagnosis can be a challenge. Very few data can support treatment decisions as cardiac manifestations of this systemic disorder are rare. METHODS AND RESULTS: We reviewed current guidelines, cohort studies, and expert opinions concerning diagnosis and treatment of cardiac sarcoidosis...

This paper focuses on three classes of commonly used anticancer drugs, which can cause cardiotoxicity: anthracyclines, monoclonal antibodies exemplified by trastuzumab and tyrosine kinase inhibitors. Anthracyclines can induce cardiomyocyte necrosis and fibrosis. Trastuzumab can cause cardiac stunning. The tyrosine kinase inhibitors can increase systemic arterial pressure and impair myocyte contractility. In addition, radiation therapy to the mediastinum or left chest can exacerbate the cardiotoxicity of these anticancer drugs and can also cause accelerated atherosclerosis, myocardial infarction, heart failure and arrhythmias...

Nonalcoholic fatty liver disease (NAFLD) is a pathologic condition frequently observed in clinical practice. To date, the prevalence of NAFLD is approximately 25-30% among adults of the general population in Western countries but increases to approximately 70-75% among patients with type 2 diabetes mellitus. In the last decade, accumulating evidence has clearly demonstrated that patients with NAFLD have not only an increased liver-related morbidity and mortality but also an increased risk of fatal and non-fatal cardiovascular events...

BACKGROUND: Unexplained cardiac arrest may be because of an inherited arrhythmia syndrome. The role of genetic testing in cardiac arrest survivors without a definite clinical phenotype is unclear. METHODS AND RESULTS: The CASPER (Cardiac Arrest Survivors with Preserved Ejection Fraction Registry) is a large registry of cardiac arrest survivors where initial assessment reveals normal coronary arteries, left ventricular function, and resting ECG. Of 375 cardiac arrest survivors in CASPER from 2006 to 2015, 174 underwent genetic testing...

OBJECTIVES: Atrial and ventricular septal defects are commonly closed surgically with low rates of post-operative morbidity, and the long-term outcome has widely been described as benign. Nevertheless, there is an increasing understanding of late morbidity, and the possibility of postoperative chronotropic impairment is continuously questioned. Furthermore, potentially abnormal chronotropic responses may be associated with the recently demonstrated overrepresentation of late arrhythmias...

OBJECTIVE: The study aims to describe the management of a case of life-threatening yew (Taxus baccata) intoxication. BACKGROUND: The needles of the yew tree contain highly cardiotoxic taxines. Intoxication with taxines, typically as part of suicide attempts, may lead to potentially lethal arrhythmias which often require prolonged cardiopulmonary resuscitation and other supportive measures. No specific therapy has been described. In some cases, extracorporeal life support has been used...
