Filter by:We performed a prophylactic peroperative linear 1-minute cryolesion connecting the tricuspid annulus and right atriotomy to prevent IART on 15 consecutive adult patients undergoing surgery for congenital heart disease. Conduction time between electrodes placed on both sides of the cryolesion was measured on the second postoperative day. Coronary angiography and electrophysiology study using an electroanatomic mapping system to assess conduction across the line were performed three month after the operation on 13 patients.
Primary objective: - to assess the efficacy of SSR149744C for the prevention of ventricular arrhythmia-triggered ICD interventions. Secondary objectives: - to assess versus placebo the tolerability of the different dose regimens of SSR149744C in the selected population. - to document SSR149744C plasma level during the study.
In this randomized study, two energy sources for the ablation of AV nodal reentry tachycardia are compared: The standard technique of radiofrequency energy delivery is compared with the new approach of cryo-energy application.
The DAVID II Clinical Study evaluates the hypothesis that, in patients needing an ICD but without overt indications for pacing, AAI pacing with maximal concomitant drug therapy will not increase the rate of the combined endpoint of mortality or hospitalization for new or worsened heart failure as compared to patients with ventricular backup pacing.
This study evaluates the date of the first appropriate and/or inappropriate therapy in patients implanted with a Guidant PRIZM or VITALITY defibrillator and is evaluating eventual predictive risk factors for appropriate/inappropriate therapies as well as the influence of the programmed parameters on these therapies.
The objective of this study is to demonstrate the efficacy of the ENDOTAK® RELIANCEā¢ defibrillation leads connected to a defibrillator or a cardiac resynchronization defibrillator from implant until 12 months.
The purpose of this study is to assess the safety and effectiveness of the CONTAK RENEWAL 4 AVT device.
The purpose of this study is to determine the safety and efficacy of the implant of a ICD lead of defibrillation in the septum of the right ventricle
The MADIT-CRT trial is designed to determine if combined implantable cardiac defibrillator (ICD)-cardiac resynchronization therapy (CRT-D) will reduce the risk of mortality and heart failure (HF) events by approximately 25%, in subjects who are in New York Heart Association (NYHA) functional Class II with non-ischemic or ischemic cardiomyopathy and subjects who are in NYHA functional Class I with ischemic cardiomyopathy, left ventricular dysfunction (ejection fraction [EF] < or = 0.30), and prolonged intraventricular conduction (QRS duration > or = 130 ms).
Analysis of the patients' data who were rescued with extracorporeal membrane oxygenation and without ECMO. The survival rate and the weaning rate were analyzed to see the effect of ECMO on the prolonged CPR.
