Filter by:The proposed study is designed to characterize the safety and efficacy of a new extravascular implantable cardioverter defibrillator (ICD) system in humans.
The study evaluates the use of half-normal saline as an irrigant for open-irrigated catheters during left ventricular outflow tract ventricular arrhythmias ablation. By increasing the efficacy of radiofrequency energy-mediated lesion formation, half-normal saline has the potential to reduce procedural times and improved acute and long-term outcomes.
This study will test the hypothesis that implantation of a subcutaneous implantable cardioverter defibrillator (S-ICD) without performing a defibrillation test is non-inferior to S-ICD implant with a defibrillation test with regards to the primary endpoint failed first shock in a spontaneous arrhythmia episode when implant position is confirmed with PRAETORIAN score.
A Retrospective Propensity Matched Study comparing: - real zero fluoroscopy catheter ablation - conventional fluoroscopy catheter ablation without 3D system - conventional fluoroscopy catheter ablation with 3D system
Ventricular arrhythmias arising from cardiac outflow tract affect quality of life and can cause decrease in left ventricular ejection fraction. Drugs used for treating those arrhytmias may be ineffective or may have side effects. Radiofrequency catheter ablation can be used safely for treatment of outflow tract arrhythmias. There are different sites where those ventricular arrhythmias may originates, each site has different electrocardiographic characteristics, different procedural success rates and challenges in localization and ablation.
Patients are screened for significant arrhythmias and other possibly significant ECG-patterns directly after discharge and two weeks after myocardial infarction using wearable devices. The home monitoring data will be linked with extensive data from electronic health records collected before, during hospital stay and after discharge. The purpose of the study is to clarify whether home monitoring of continuous ECG-signals can be used to predict and prevent serious adverse events after myocardial infarction.
This retrospective multicenter cohort will validate an independent association of electrocardiographic (ECG) global electrical heterogeneity (GEH) measures with sustained ventricular tachyarrhythmias and appropriate ICD therapies in systolic heart failure patients with primary prevention ICD, and will validate and re-calibrate GEH ECG risk score for prediction of sustained ventricular tachyarrhythmias and appropriate ICD therapies in systolic heart failure patients with primary prevention ICD.
This study will examine the safety and efficacy of intramural needle ablation (INA) in the treatment of intramural ventricular arrhythmias in patients for whom standard RF ablation has been unsuccessful. The clinical team hypothesize that the increased current density and improved rates of transmural lesion creation seen with intramural needle ablation will lead to successful arrhythmia termination with minimal or no increased risk of complication.
The vascular surgery is a highest risk procedure when considering postoperative complications associated with the cardiovascular system. The leading clinical presentation is acute hemodynamic decompensation. However, one of the possible pathomechanisms might be repolarization disturbances. Many of perioperative risk factors of cardiac complications are modifiable. The identification may help in the global perioperative risk reduction. Aim: The aim of the study was an identification of the factors which may release clinically overt repolarization disturbances. Methods: The study group consisted of 100 patients, diagnosed with abdominal subrenal aortic aneurysms or peripheral arterial disease scheduled for an elective "open" vascular surgery procedure. The authors investigated whether age, gender, comorbidities or some perioperative factors (including hemodynamic, metabolic or genetic) were related to the occurrence of clinically concealed repolarization disturbances or clinically disclosed cardiac complications in postoperative time up to 30 day and one year after vascular surgery procedure.
This study is intended to compare the feasibility, safety and efficacy of a zero-fluoroscopy approach using Ensite NavX as the only imaging modality with conventional fluoroscopic approach for the catheter ablation of idiopathic ventricular arrhythmias; conventional fluoroscopic approach use fluoroscopy plus Ensite NavX or plus Carto as the imaging modality.
