Study for Recurrent Ventricular Tachycardia (VT) Ablation

This study is for people aged 18 or older who have experienced sustained Monomorphic Ventricular Tachycardia (MMVT), a type of fast heart rhythm, within the last six months. It compares two ways to perform a procedure called VT ablation, which uses heat to correct heart rhythm problems. One method uses a new mapping technique called Isochronal Late Activation Mapping (ILAM) to guide the ablation. The other method uses a standard technique called High Density Voltage Mapping. The study aims to see if the ILAM-guided ablation is as effective as the standard method in preventing VT from coming back and reducing hospital stays. We are looking for 360 participants for this study, but the current recruitment status is unclear.

Study design
This is a randomized controlled trial, meaning participants will be assigned by chance to one of two treatment groups. It involves 360 participants and compares two different ablation strategies.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for one year after the procedure to check for recurrent VT and hospitalizations.
