Filter by:Radiofrequency ablation is a procedure done in the Catheterization Laboratory to help correct specific problems that cause the heart to beat faster than it should. Quality of life includes the physical as well as the emotional aspects of a patient. Doctors have always tried to take care of a medical problem with minimal physical and emotional risk. It is assumed that once the medical problem is fixed, the patient will have an improved quality of life. To know if this assumption is true, the investigators are asking children scheduled for this procedure, along with their family, to answer questions before the ablation, then answer the same questions 5-6 months after the ablation.
The REFLEx Study will evaluate if ENDOTAK RELIANCE G defibrillation leads with GORE ePTFE-covered coils are as good as or better than other comparative commercially available defibrillation leads with respect to electrical performance and termination efficacy in spontaneous tachyarrhythmic episodes.
We are studying the genetics of human cardiovascular and neuromuscular disease. There are many different genetic regions that have been associated with the development of cardiomyopathy. An equal number of genetic regions have been associated with muscular dystrophy and there is overlap because some of the identical genes, when mutated, produce both cardiomyopathy and muscular dystrophy. We are working to identify genes and gene mutations associated with cardiomyopathy, arrhythmias and muscular dystrophy. We propose to screen these samples for mutations in genes known to be involved in these disorders.
The purpose of this study is to learn the effects of a test drug on heart rhythms, which may become life-threatening if left untreated, and to provide data to see if the drug is well tolerated and safe.

The overall objective of the study is to quantify the true prognostic value and cost-effectiveness of routine follow-up visits in patients who receive an approved pacemaker of any type for the first time.
The purpose of this cross-sectional study was to determine the interrelationships between health status and measures of cardiac performance in children 6 to 18 years of age with congenital heart disease who have undergone a Fontan procedure as surgical treatment for functional single ventricle. The goal was to develop a data set that will permit identification of a clinically relevant endpoint for subsequent trials of medical management of the Fontan patient.
The purpose of this study is to determine if opening blocked arteries with heart balloons and stents prevents heart rhythm problems in individuals 3 to 28 days after a heart attack.
This trial compares the safety and effectiveness of catheter ablation for PAF with antiarrhythmic drug therapy. The investigational catheter being studied is the NAVISTAR® THERMOCOOL® irrigated-tip catheter. At the time of this study, the NAVISTAR® THERMOCOOL® catheter was FDA-approved for commercial distribution in the U.S. for treating patients with Type I atrial flutter and drug refractory monomorphic ventricular tachycardia post myocardial infarction. The catheter was approved for use in Europe for endocardial ablation for treating cardiac arrhythmias.
The objective of the SOFA trial is to investigate whether supplemental intake of n-3 polyunsaturated fatty acids (n-3 PUFA) from fish oil can reduce the recurrence of life-threatening ventricular arrhythmias in patients with an implantable cardioverter defibrillator (ICD).
