Assessment Of MRI In Patients With Implanted Cardiac Devices

Cardiac implantable electronic devices (cIEDs) generally refer to implanted pacemakers and defibrillators for patients with cardiac disorders affecting their heart rhythm. Previously, cIEDs have been regarded as a contraindication to magnetic resonance imaging (MRI) scans, with concerns that the magnetic fields of the MRI may cause problems with the patient's ...

Effectiveness Study of Circumferential vs. Segmental Ablation in Paroxysmal Atrial Fibrillation

Despite more than a decade of clinical experience and investigation, the optimal approach to ablation of paroxysmal atrial fibrillation (PAF) still remains controversial. There are currently two strategies for ablation of PAF: (1) circumferential pulmonary vein ablation (CPVA) and (2) segmental pulmonary vein isolation (SPVI). There are advantages and disadvantages ...

A Registry to Determine the Clinical and Genetic Risk Factors for Torsade De Pointes

BACKGROUND AND SIGNIFICANCE Drug-induced long QT syndrome (LQTS), and the subsequent fatal arrhythmia torsade de pointes (TdP), is an important side effect associated with the use of a number of medications. Prolongation of the QT interval is the most common cause of withdrawal of medications already on the market, and ...

Arrhythmias in Post-Myocardial Infarction Patients

Patients with acute myocardial infarction have exceptionally high mortality rates exceeding 10% during the first year post-MI. The incidence of sudden cardiac death after acute myocardial infarction is the same with ST-elevation and non-ST elevation myocardial infarction. The risk of disabling stroke and sudden cardiac death is high especially during ...

Phase N/A

Arrhythmia Prediction Trial

Sudden Cardiac Death (SCD) threatens survival of Coronary Artery Disease and Dilated Cardiomyopathy patients with Heart Failure. Discovering efficient SCD risk stratification markers is of high importance. In this study, heart failure patients will be risk stratified with indices from the Myocardial substrate (QRS, fragmented QRS, Late potentials, LVEF), indices ...

Phase N/A

Analysis in the EMERGEncy Between TransVenous Cardiac PACIng Guided by Fluoroscopy Versus Echocardiogram

Approximately 150 subjects will be recruited over a planned recruitment period of 18 months. Patients will be submitted to ecchocardiogram using Philips Envisor, and electrocardiogram with Philips Healthcare PageWriter TC30.

Phase N/A

Antiarrhythmic and Cardioprotective Effects of Atorvastatin Versus Magnesium Sulfate in Cardiac Valve Replacement Surgery

Arrhythmia is a common complication after cardiac valve surgery. Postoperative atrial fibrillation (POAF) is the most common type of arrhythmia after cardiac surgery. It has different leading causes, including myocardial injury, inadequate myocardial protection, the effect of cardiopulmonary bypass, and electrolyte imbalance. Beta blockers, amiodarone, and magnesium sulfate are used ...


Implantable Cardioverter Defibrillator (ICD Registry)

In January 2005 the Centers for Medicare and Medicaid Services (CMS) expanded the covered indications for primary prevention implantable cardioverter defibrillators (ICDs) to incorporate the findings from the Sudden Cardiac Death Heart Failure Trial (SCDHeFT) and the Multicenter Automatic Defibrillator Implantation Trial II (MADIT II). As part of this expansion, ...

Phase N/A

The Use of Remote Magnetic Navigation in Catheter Ablation of Heart Arrythmia

The purpose on this study is to show the utility and the safety by using the remote magnetic navigation of ablation catheters with the Stereotaxis equipment at ablations of - atrial fibrillation, atrial flutter and other arrythmias - childrens arrythmias - arrythmias of patients with pacemaker or ICD (Implantable Cardiac ...

Phase N/A

Pathophysiology of Orthostatic Intolerance

The purpose of this study is to describe the mechanism of orthostatic intolerance, relying on cardiovascular physiological studies. The syndrome is of undetermined etiology, but the syndrome causes impairment of a number of young adults, females more than males, with symptoms of tachycardia, fatigue, lightheadedness, palpitations, blurred vision, chest discomfort, ...
