Filter by:The goal of this clinical trial is to demonstrate that the OPTIMIZER® Integra CCM-D System (the "CCM-D System") can safely and effective convert induced ventricular fibrillation (VF) and spontaneous ventricular tachycardia and/or ventricular fibrillation (VT/VF) episodes in subjects with Stage C or D heart failure who remain symptomatic despite being on guideline-directed medical therapy (GDMT), are not indicated for cardiac resynchronization therapy (CRT), and have heart failure with reduced left ventricular ejection fraction (LVEF ≤40%). Eligible subjects will be implanted with the CCM-D System. A subset of subjects will be induced into ventricular fibrillation "on the table" in the implant procedure room. During the follow-up period, inappropriate shock rate and device-related complications will be evaluated. The follow-up period is expected to last at least two years.
The Prospective Cardiac Ultrasound Imaging Study is a single center, single arm, feasibility study. The study aims at collecting cardiac ultrasound data from patients diagnosed with ventricular tachycardia, during rest and short breath hold sequences. This study is part of the engineering studies linked to the CardioKit-Minimum Viable Product project. The CardioKit prototype used in the study can monitor cyclical heart-beat motion, cyclical respiratory motion and non-cyclical heart position changes while the patient is lying in supine position.
The goal of this observational study is to learn about the factors which determine how well ventricular tachycardia (VT) is tolerated. The main questions it aims to answer are: 1. What impact does coronary artery disease have on the ability for a patient to tolerate VT? 2. Does treatment of coronary artery disease with stents improve the tolerability of VT? Participants who are undergoing a clinically indicated coronary angiogram or coronary angioplasty procedure will have measurements of blood pressure, coronary pressure and coronary flow made during pacing at a range of heart rates.
This post-approval study (PAS) is designed to provide continued clinical evidence to confirm the long-term safety and effectiveness of the FlexAbilityTM Ablation Catheter, Sensor EnabledTM (FlexAbility SE) for the treatment of ventricular tachycardia in a post-market environment. This is a prospective, single arm, open-label, multi-center, observational study.
Ventricular tachycardia (VT) is a life-threatening cardiac rhythm disturbance which leads to sudden cardiac death (SCD), ventricular fibrillation, electrical storm, hemodynamic collapse, and syncope. VT patients with cardiomyopathy (diseased/scarred cardiac muscle) have the highest risk of SCD (<1-4%) and recurrent VTs (15-35%). Although an implantable cardiac defibrillator (ICD) is the most effective treatment option to prevent SCD, it does not eliminate it. Without VT prevention, recurrent VT and ICD shocks may increase the risk of heart failure and death. The primary objective is to determine the optimal treatment strategy to maximize event-free survival among cardiomyopathy patients with ventricular tachycardia (VT) by the creation of a prospective, multicenter, longitudinal cohort. Also, the investigators will evaluate the epidemiology of VT, adherence to guidelines, safety, effectiveness, and cost-effectiveness of current treatment options for secondary prevention of VT in the real-world Canadian VT population.
The purpose of this study was to explore the safety and efficacy of a Pulsed Field Ablation（PFA） Device and Force Sensing Pulsed Field Ablation Catheter in the treatment of Paroxysmal Supraventricular Tachycardia（PSVT）
STEP ICD is a premarket, exploratory, early feasibility, interventional study designed to evaluate the preliminary safety and performance of the Investigational Devices. The study is intended to inform the final device design which will be further evaluated in traditional feasibility and /or pivotal clinical investigations. The primary safety objective is to characterize safety of the EV-ICD Lead through 3 months post-implant. The primary performance objective is to characterize sensing and conversion of induced VF with the EV-ICD Lead up to 3 months post-implant.
The purpose of this study was to explore the safety and efficacy of a Pulsed Field Ablation Device and Force Sensing Pulsed Field Ablation Catheter in the treatment of Paroxysmal Supraventricular Tachycardia.
RADIATE-VT is a pivotal, multicenter, randomized trial comparing safety and efficacy between cardiac radioablation (CRA) using the Varian CRA System and repeat catheter ablation (CA), for patients with high-risk refractory ventricular tachycardia (VT) who have experienced VT recurrence after CA and are candidates for additional CA.
NODE-202 is a Phase 2, multicenter, multinational, single dose, open-label, 2-part, sequential design study in pediatric patients with an established diagnosis of paroxysmal supraventricular tachycardia (PSVT) presenting with a symptomatic episode of PSVT. In Part 1, at least 30 patients aged 12 to <18 years will be enrolled and treated with etripamil nasal spray (NS). Efficacy, safety, tolerability and PK (for at least 12 patients) will be assessed after administration of 70 mg etripamil NS (Part 1A). At least 18 subsequent patients will be enrolled and treated with the etripamil NS with the dose determined by the Pharmacokinetic (PK) analysis and will undergo efficacy and safety/tolerability assessments (Part 1B). In Part 2, at least 30 patients aged 6 to <12 years will be enrolled and treated with etripamil NS at a dose selected based on appropriate body size-based modeling, as well as efficacy, safety/tolerability, and PK data collected in Part 1. Efficacy, safety, tolerability and PK (for at least 12 patients) will be assessed after administration of etripamil NS (Part 2A). At least 18 subsequent patients will be enrolled and treated with the etripamil NS with the dose determined by the PK analysis and will undergo efficacy and safety/tolerability assessments (Part 2B). The study will include the following visits: A Screening Visit, A Treatment Visit, , and A Follow-Up/End of Study Visit.
