23,682 | Three-dimensional mapping, recording and ablation in simulated and induced ventricular tachyarrhythmias during mechanical circulatory support using the percutaneous heart pump. | Due to their internal rotating magnets, conventional impeller-driven percutaneous ventricular assist devices (PVADs) yield high-frequency electrogram artifact and electromagnetic interference (EMI) when used with magnetic-based 3D electroanatomic mapping systems. The new percutaneous heart pump (PHP; Abbott, Chicago, I... |
23,683 | Oral procainamide as pharmacological treatment of recurrent and refractory ventricular tachyarrhythmias: A single-center experience. | Antiarrhythmic therapy for recurrent ventricular arrhythmias in patients who have undergone catheter ablation, and in whom amiodarone and/or beta-blockers were ineffective or contraindicated, is a controversial issue.</AbstractText>The present study sought to evaluate the efficacy and tolerability of oral procainamide ... |
23,684 | Atrial fibrillation and heart failure: A contemporary review of current management approaches. | Atrial fibrillation (AF) and heart failure (HF) frequently coexist and complicate the course of treatment of each other. AF with rapid ventricular conduction can lead to tachycardia-mediated cardiomyopathy, which is a reversible cause of cardiomyopathy. However, in most cases, AF is the manifestation of various underly... |
23,685 | Arrhythmias in adults with congenital heart disease and heart failure. | Arrhythmias and heart failure are among the most common complications encountered by adults with congenital heart disease (CHD). In this contemporary review, we explore the interactions between arrhythmias and heart failure and discuss management strategies. Major knowledge gaps are highlighted throughout. Interactions... |
23,686 | Cardioprotective effects of dantrolene in doxorubicin-induced cardiomyopathy in mice. | Doxorubicin (Dox) is a potent chemotherapeutic agent, but its usage is limited by dose-dependent cardiotoxicity. Intracellular calcium dysregulation has been reported to be involved in doxorubicin-induced cardiomyopathy (DICM). The cardioprotective role of RyR stabilizer dantrolene (Dan) on the calcium dynamics of DICM... |
23,687 | Atrial fibrillation associated with heart failure treated by a 2-lead CRT-DX system (BIO-AffectDX): Study design and clinical protocol. | Evidence to support use of cardiac resynchronization therapy (CRT) among patients with both heart failure (HF) and atrial fibrillation (AF) is largely limited to retrospective or post hoc subanalyses. Data from a prospectively enrolled and contemporary cohort are needed.</AbstractText>We aim to better characterize the ... |
23,688 | Continuous ECG monitoring versus mobile telemetry: A comparison of arrhythmia diagnostics in human- versus algorithmic-dependent systems. | Clinicians rarely scrutinize the full disclosure of a myriad of FDA-approved long-term rhythm monitors, and they rely on manufacturers to detect and report relevant rhythm abnormalities.</AbstractText>The objective of this study is to compare the diagnostic accuracy between mobile cardiac telemetry (MCT), which us... |
23,689 | Cardiovascular Burden and Adverse Events in Patients With Esophageal Cancer Treated With Chemoradiation for Curative Intent. | The aim of this study was to characterize the cardiovascular disease (CVD) profile and describe the incidence and characteristics of cardiovascular (CV) events in patients with esophageal cancer (EC) following chemoradiation and surgery.</AbstractText>Underlying CVD is a concern in patients with EC receiving curative t... |
23,690 | Successful ablation of bifocal premature ventricular complexes from both left bundle branches triggering polymorphic ventricular tachycardia in long QT syndrome 2: a case report. | A 19-year-old woman with an established diagnosis of long QT syndrome (LQTS) 2 and underlying KCNH2-mutation was referred to our centre for recurrent polymorphic ventricular tachycardia (VT) and ventricular fibrillation (VF) refractory to medical therapy and bilateral thoracic sympathectomy.</AbstractText>Holter monito... |
23,691 | Veno-Arterial Extracorporeal Membrane Oxygenation for Patients Undergoing Heart Transplantation: A 7-Year Experience. | <b>Objective:</b> Primary graft dysfunction (PGD) is the leading cause of early death after heart transplantation. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) can provide temporary mechanical circulatory support and time for functional recovery of the transplanted heart. The purpose of this study was to... |
23,692 | Risk prediction in patients with low-flow, low-gradient aortic stenosis and reduced ejection fraction undergoing TAVI. | Patients with low-flow, low-gradient aortic stenosis (LFLG AS) and reduced left ventricular ejection fraction (LVEF) are known to suffer from poor prognosis after transcatheter aortic valve implantation (TAVI). This study aimed to develop a simple score system for risk prediction in this vulnerable subset of patients.<... |
23,693 | Phenotyping of acute decompensated heart failure with preserved ejection fraction. | The pathophysiological heterogeneity of heart failure with preserved ejection fraction (HFpEF) makes the conventional 'one-size-fits-all' treatment approach difficult. We aimed to develop a stratification methodology to identify distinct subphenotypes of acute HFpEF using the latent class analysis.</AbstractText>We est... |
23,694 | Blood Flow Dynamics in a Giant Left Atrial Appendage Aneurysm Visualized by 4D-Flow CMR. | Aneurysms of the left atrial appendage (LAA) are rare entities that often require surgical intervention. We demonstrate multimodality imaging features of a giant LAA aneurysm, with a focus on 3-dimensional blood flow dynamics by using 4-dimensional-flow cardiac magnetic resonance. (<b>Level of Difficulty: Advanced.</b>... |
23,695 | Frequent cyclic variation of heart rate is associated with left ventricular diastolic dysfunction in patients without ischemia. | Cyclic variation of heart rate (CVHR) associated with sleep-disordered breathing reflects cardiac autonomic responses to apneic/hypoxic stress.

23,696 | Evaluation of a Novel Left Ventricular Assist Device for Resuscitation in an Animal Model of Ventricular Fibrillation Cardiac Arrest. | We evaluated an independently developed novel percutaneous implantable left ventricular assist device for resuscitation in a pig model of ventricular fibrillation cardiac arrest. The model was established in 10 domestic pigs by blocking the anterior descending coronary artery with a balloon after anesthesia. With venti... |
23,697 | Chemotherapy-Induced Arrhythmias. | Cardio-oncology is a subspeciality within cardiology that has developed primarily as a consequence of the cardiovascular implications of cancer and its therapeutics. Arrhythmias are increasingly recognized as an adverse feature of many chemotherapeutic agents. This relationship is poorly defined and studied in the lite... |
