Filter by:This study will assess the outcomes of using magnetic navigation to treat ventricular tachycardia (VT) or premature ventricular contractions (PVCs) that occur for unknown reasons and are not related to structural heart disease.
In children, radiofrequency catheter ablation (RFCA) or cryoablation are highly effective treatments for supraventricular tachycardia treatment. General anesthesia is often required to ensure comfort during the prolonged procedure and to assure immobility in order to facilitate accurate mapping and subsequent ablation of the accessory pathway and/or arrhythmogenic focus. Successful anesthetic management of this patient population requires adequate suppression of sympathetic responses during the procedure while electrophysiological parameters remain unaltered for mapping purposes and subsequent ablation. Although Sevoflurane (SEVO) and Isoflurane (ISO) are two commonly used and evaluated volatile anesthetic agents for ablation procedures, comparison of those agents has not been performed previously not in adults, not in children. Hypothesis Time required for basic EP intervals, successful induction of SVT and successful RFCA or cryoablation in children will not be different between patients undergoing Sevoflurane or Isoflurane-based anesthesia.
The purpose of this study is to find out if Esmolol is a safe and effective alternative treatment compared to standard treatment using a long acting beta blocker drug, in controlling abnormal heart rate before, during and immediately after surgery.
Implantable Cardioverter Defibrillators (ICDs) provide a shock or pacing therapy to bring back a normal heart beat when a patient experiences a dangerous abnormal heart rhythm such as ventricular tachycardia (VT). ICDs are very successful in bringing back a normal heart beat when VT occurs, but they do not prevent further dangerous heart rhythms from occurring. This study is designed to determine the best way to manage patients who have an ICD and who continue to have episodes of VT. There are two methods for treatment the VT: 1) Ablation, and 2) Medication. An ablation procedure involves placing a flexible catheter (insulated wire) in the groin area and threading it into the heart. After the doctor has located the affected area responsible for the VT, radiofrequency energy is delivered by the power generator through the catheter to the inside of the heart. The radiofrequency energy ablates (burns) a small area of the heart tissue thought to cause the VT. A medication called Amiodarone is an "anti-arrhythmic" prescribed to prevent abnormal heart rhythms from recurring. The purpose of this study is to compare these two different methods for treating VT. Treatment with ablation and amiodarone are both considered the standard of care for patients with VT but they have not been compared directly in a study like this before.
This research study is a prospective, single-center, feasibility study designed to assess the possibility to detect hemodynamic changes during tachycardia episodes using tissue perfusion.
The aim of the study is the comparison of two different leads in their capabilities to detect episodes and duration of paroxysmal atrial fibrillation (AF) and atrial tachyarrhythmia (AT), and the rejection of far field sensing of the far field R-wave (FFRW).
To demonstrate that ablation with the Therapy Cool Path Duo cardiac ablation system can eliminate ischemic VT and that its use does not result in an unacceptable risk of serious adverse events.
Patients with implantable cardioverter defibrillators (ICDs) should undergo regular device follow-ups every 3 months, to verify proper ICD function. However, many follow-ups are uneventful, revealing no relevant changes related to the implanted device and in the patient's diagnostic and therapeutic status. For time and economic reasons, longer follow-up intervals are frequently used although they are not according to recommendations. This may increase the delay in detection of relevant changes in the disease and in deviations from optimal ICD therapy in the individual patients. In the newest ICDs, the essential parameters reflecting safety and appropriateness of ICD therapy (threshold, impedance, intracardiac electrogram, etc.) are transmitted via Home Monitoring on a daily basis, to an internet platform accessible by the attending physician. In the present study, the investigators evaluate safety and efficacy of 12-month follow-up intervals in ICDs with Home Monitoring capability, as compared with conventional 3-month follow-up scheme.
In this study, we will compare the quality of life in veterans having ICD who attend the ICD support groups to those who do not. We ask them to answer a set of quality of life questionnaires at baseline and then at 3,6,9 and 12 month visits. These questionnaires would be analyzed to assess if attending support groups made a difference. These results will be compared to a similar study done at Emory University on non veterans.
BIOTRONIK Home Monitoring (HM) service enables the doctors to safely follow up (FU) their ICD and CRT-D patients in a remote fashion, with fewer in-clinic consultations. This may result in a more efficient FU and cost-savings for the health care payer. The EuroEco study: 1. Outlines a new HM-based FU model for the ICD and CRT-D patients that combines in-clinic consultations and regular check ups of the patient/ICD/CRT-D data received through the HM service. 2. Compares the direct costs for physicians and clinics for the HM-based FU of ICD and CRT-D patients versus the traditional FU. 3. Compares the indicators of patients' safety between the two FU models.
