Catheter Ablation of Haemodynamically Not-tolerated Electrical Storm in

Status Not yet recruiting

Clinical Trial Summary

This is a multi-center, parallel-group, randomized, open-label trial evaluating the clinical outcome and efficacy of emergency catheter ablation versus conventional stepped-care strategies in patients with haemodynamically not-tolerated ventricular tachycardia (VT).

Clinical Trial Description

The prognosis of haemodynamically not-tolerated VT in structural heart disease is very poor, with a high 30-day mortality rate >30%, resulting in extremely heavy medical burden. Current guidelines lack specific recommendations for managing this condition. The prevailing treatment strategy involves a sequential approach-beginning with anti-arrhythmic drugs, sedation, and anesthesia, followed by haemodynamic mechanical support devices. Catheter ablation is only used as the final rescue treatment. Typically, patients undergo repeated electrical cardioversion and receive multiple vasopressors and antiarrhythmic drugs, facing increased risks of complications from enhanced haemodynamic support. Studies have shown that these patients often eventually progress to irreversible pump failure, miss the window for effective catheter ablation, and ultimately die. Early cardioversion and maintenance of sinus rhythm, may significantly reduce mortality rates in patients with haemodynamically not-tolerated VT. Therefore, emergency catheter ablation is expected to reduce the mortality of haemodynamically not-tolerated ventricular tachycardia. In this study, we aim to evaluate the effect of emergency catheter ablation in haemodynamically not-tolerated ventricular tachycardia. Current study will include 96 patients, and all patients will be randomized to either the emergency catheter ablation arm or stepped-care strategies arm in a 1:1 fashion. The follow-up duration is 1 year. The primary outcome is a composite outcome of VT recurrence, cardiovascular re-hospitalization, and all-cause mortality. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
