Filter by:This is an early feasibility, non-randomized, open-label, single group, interventional study to be conducted in up to 20 US subjects to evaluate the technical feasibility of the Durablate Catheter and Thermedical Ablation System to eliminate or control sustained, monomorphic ventricular tachycardia (VT) in patients with VT refractory to drug and conventional catheter ablation with acceptable procedural safety.
Aim of this study is to collect data from pace mapping performed in three groups of patients : patients presenting ventricular tachycardia and infarction history, patients presenting infarction history without presenting ventricular tachycardia, and in patients without structural heart disease.
Phase I/II study of 4-D Navigated Non-invasive radiosurgical ablation of ventricular tachycardia (NIRA-VT).
Carvedilol is known to be effective in reducing ventricular arrhythmias and mortality in patients with heart failure. It is suggested that one of the mechanisms is its ability to block store overload-induced Calcium release which activates spontaneous calcium release by Ryanodine receptors. Ventricular outflow tract tachyarrhythmia is known to be associated with calcium overload due to activation of Ryanodine receptors. The aim of this study is to evaluate the efficacy of Carvedilol on premature ventricular complex(PVC)/ventricular tachycardia(VT) originating from outflow tract.
The goal of this study is to test the efficacy of the new imaging/simulation ("virtual heart") approach for determining the optimal ablation sites in patients with VT, which render post-infarction VT non-inducible. The study will test both the acute outcome of the ablation procedure, and the effect the use of the predicted targets has upon procedure time.
The goal of this study is to determine the optimal treatment for patients who receive a single shock from their implantable cardioverter defibrillator (ICD). All participants in this study will be fitted with a special electrode vest to detect the origin of heart rhythm abnormalities and then they will undergo a procedure called Non-Invasive Programmed Stimulation (NIPS). This procedure involves sedating a participants with anesthesia and then using the participant's own ICD to try to stimulate the heart to go into ventricular tachycardia. If this procedure is unable to induce the participant into ventricular tachycardia, then the participant will just be managed with usual care and will not be placed on any additional medications and will not undergo an ablation. However, if the NIPS induces the ventricular tachycardia, the electrode vest will be used to determine the origin of the abnormal heart rhythm inside the heart. After a successful NIPS procedure, the participants will be randomly assigned to either be placed on medication therapy or undergo catheter ablation. The outcomes from all three groups will be compared and the researchers hope to better understand which participants are most likely to benefit from watchful waiting versus medication versus catheter ablation.
RAPID-VT Pilot is a single centre prospective cohort pilot study to assess the feasibility, safety and efficacy of catheter ablation of ventricular tachycardia (VT) guided by a novel real-time software to localize the origin of VT during the ablation procedure.
This clinical investigation is intended to demonstrate the safety and effectiveness of ventricular ablation therapy using the FlexAbility Sensor Enabled Ablation Catheter in patients with drug-refractory monomorphic ventricular tachycardia in whom ventricular tachycardia recurs despite antiarrhythmic drug therapy or when antiarrhythmic drugs are not tolerated or desired.
This is a two-part, multi-center, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of etripamil nasal spray (NS) self-administered by patients who experience an episode of paroxysmal ventricular tachycardia (PSVT) in an at-home setting. Part 1 comprised the conduct of the NODE-301 study up to the date of the adjudication of 150th positively adjudicated PSVT episode and Part 2 comprises the conduct of the NODE-301 study after the completion of Part 1. The RAPID Study (NODE-301 - Part 2) will enroll patients enrolled during Part 1 who had not dosed with the double-blind study drug, or had not discontinued the study before the adjudication of the 150th positively adjudicated PSVT episode in Part 1, and patients enrolled into the study following the completion of Part 1. The study will continue for approximately 6 months after the date of the adjudication of the 180th positively adjudicated PSVT episode (the data on which the primary efficacy analysis of RAPID will be conducted). The study will include the following visits: A Screening Visit, A Test Dose Randomization Visit, Monthly Follow-up Visits, A Randomized Treatment Period, A Randomized Treatment Period Follow-Up Visit, An Open-Label Treatment Period, and A Final Study Visit.
Sudden cardiac death is a frequent cause of cardiovascular mortality. Numerous rhythmic risk assessment criterion have been described targeting the substratum, the cardiac nervous tone or the trigger of arrhythmias. Development of ventricular tachycardia ablation in the past few years show interesting results preventing the recurrence of ventricular arrhythmias.
