Filter by:BELIEVE-SVT is a European multi-centre, retrospective registry in tertiary hospitals performing electrophysiological study in patients with palpitations considered clinically suggestive of paroxysmal supraventricular tachycardia by a cardiologist and without electrocardiographic documentation of tachycardia or preexcitation. Clinical characteristics, results of electrophysiological study and ablation, complications, and clinical outcomes during follow-up will be analysed.
The purpose of this study is to assess the performance and safety of using the investigational catheter.
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.
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.
Vistag SurPoint is a proprietary module that generates a numerical tag index which can be used as multiparametric lesion quality marker to guide ablation in the clinical setting for ablation of atrial arrhythmias. SurPoint tag index has studied to guide ablation of ventricular arrhythmias, such as premature ventricular complexes, but its effectiveness and safety for ablation of Ventricular Tachycardia in patient with Ischemic and Non-Ischemic Cardiomyopathies is not well established. In this single center prospective observation registry, a ventricular ablation strategy utilizing radiofrequency delivery duration cut off determined by a maximum Surpoint index value of 550 will be compared to conventional operator determined duration of radiofrequency delivery based on combination of time (i.e. 30, 60, 90, and 120 seconds), magnitude of impedance drop, attenuation of abnormal electrograms, and achieving non-capture with high-output pacing after ablation. The Surpoint Tag Index Ablation group will be matched with a control group of patients undergoing VT ablation using the conventional time-based radiofrequency strategy and the patients in this group will be selected using propensity matching based on relevant baseline patient and clinical characteristic variables. Primary outcomes of interest: Recurrence of sustained ventricular tachycardia or Internal Cardiac Defibrillator Therapy. Secondary outcomes of interest: Hospitalization for ventricular tachycardia, repeat ablation procedures, all-cause mortality, acute procedural complications, rate of steam pops during ablation procedures Follow up: Up to 24 months after ablation procedure. Follow up will be obtained by office visits and device interrogation reports.
The purpose of this study is to assess the performance and safety for the use of the investigational catheter for intracardiac mapping in the atria and ventricles.
The SECURE EV Study is a prospective, multi-center, single-arm study without concurrent or historical controls. The objectives of the study are 1) to characterize safety of the AtaCor EV-ICD Lead up to 90 days post-implant, and 2) to characterize sensing and conversion of induced VF up to 90 days post-implant.
Local abnormal ventricular activity (LAVA) is composed of high-frequency, mainly low voltage signals that represent near-field signals from slow-conducting tissue and thus potential VT isthmuses. The identification of LAVA potentials and their modification have usually been a complimentary component of the substrate-based modification of scar related ventricular arrhtyhmias. With better identification through technical solutions and improved algorithms, LAVA modification may be feasible for treatment in therapy refractory VT.
The PASS PULL EV-ICD Study is a prospective, multi-center, single-arm study without concurrent or historical controls. This initial concept feasibility study is primarily intended to demonstrate that the EV-ICD Lead can be safely positioned within the anterior mediastinum as intended using the AtaCor delivery system. The study will secondarily characterize the ability for the EV-ICD Lead to facilitate VF sensing and defibrillation.
