Filter by:This study is a single-arm, prospective, multi-center study to assess clinical performance of the SHERLOCK 3CG™ Diamond Tip Confirmation System (TCS) with MODUS II software for confirming correct tip position of peripherally inserted central catheters (PICCs) in adult subjects with altered cardiac rhythm.
Premature Ventricular Complex (PVC) ablation is performed in certain indications. Generally acutely abolition of PVC at the time of ablation accepted as successful ablation. However in some patients this effect occurs lately. In this study investigators sought late effect of ablation
Premature ventricular contractions (PVCs) coexist in patients with heart failure (HF) and LV dysfunction. Frequent PVCs have shown to induce a reversible cardiomyopathy (PVC-CM). This clinical pilot study will enroll 36 patients with frequent PVCs (burden >10%) and CM (LVEF <45%) and randomize them to either: 1) RFA or 2) AADs. Prior to treatment, patients will undergo a baseline cardiac MR if clinically indicated followed by 3-month observation period (optimal HF medical therapy). Changes in LV function/scar, PVC burden/arrhythmias and clinical/functional status (QOL, HF symptoms and admissions, NYHA class) and adverse events will be assessed throughout the observation period and compare with PVC suppression strategies (RFA or AAD). Similar comparison will be made between RFA and AAD treatment groups during a 12-month follow up using a Prospective Randomized Open, Blinded End-point (PROBE) study design. The treatment regimens will be compared in an intention-to-treat analysis. In addition, a total of 20,000 consecutive ambulatory ECG Holter monitors from all participating centers will be screened to identify all patients with probable diagnosis of PVC-CM. This pilot study is intended to estimate the prevalence of this clinical entity and pave the way for a large full scale randomized trial to identify best treatment strategy for patients with PVC-CM. Treating and reversing this underestimated PVC-CM may improve patient's health and subsequently decrease HF healthcare spending.
Unblinded, controlled, non-randomized, mechanistic study to determine whether physiological mechanisms underlying PVC are sensitive to adenosine. One hundred subjects undergoing clinically-indicated, standard-of-care cardiac electrophysiology study (EPS) procedure for PVCs will receive adenosine and/or verapamil to learn if their arrhythmias are inducible similarly to sustained ventricular tachycardia.
Several reports have shown the utility of PVC ablation with cryo catheters. The aim of this study is to compare the outcomes and safety of Cryo vs. RF for PVCs.
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.
For therapy of symptomatic premature ventricular complexes (PVCs) in subjects with structural heart disease the current European Guidelines for the management of patients with ventricular arrhythmias and the prevention of second cardiac death recommend catheter ablation as well as amiodarone with a class IIa indication. Due to the lack of randomized data this study investigates the comparison of catheter ablation and amiodarone for PVC treatment in patients with structural heart disease. Therefore, patients will be randomized to one of two treatment strategies: 1) catheter ablation, or 2) amiodarone.
Phase I/II Study of EP-guided Noninvasive Cardiac Radioablation (ENCORE) for Treatment of Ventricular Tachycardia
To evaluate the effectiveness and safety of catheter ablation of frequent symptomatic PVCs in the pediatric population as first-line therapy compared with antiarrhythmic drugs.
The purpose of this study is to learn if taking a drug called direct oral anticoagulant after an ablation procedure keeps blood clots from forming and lowers the chance of having a stroke in patients with ventricular tachycardia or arrhythmia (VT).
