Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Our hypothesis is that patients with ventricular tachycardia (VT) and severe LV dysfunction randomized to this imaging-aided protocol will have shorter procedure duration, improved procedural hemodynamic stability, fewer acute major adverse cardiovascular events (MACE), less need for mechanical support, comparable freedom from VT at noninvasive programmed stimulation (NIPS) sub-acutely after the procedure, and at two-year follow-up compared to standard ablation approach. Herein, our outcomes of interest will be captured during the two years following as part of regular standard of care follow-ups.

Imaging-aided VT ablation
For subjects assigned to the imaging-aided VT ablation arm, CT and/or c-MRI derived myocardial scar will be merged with 3D electroanatomical mapping (EAM) prior to the ablation to allow for readily localization and characterization of VT substrates and potential re-entry circuits to be ablated. This integrated mapping of VT substrates sites to be ablated will be given to the electrophysiologist prior to the ablation.
Incorporation of CT and/or c-MRI derived myocardial scar with 3D electroanatomical mapping (EAM).
CT and/or c-MRI derived myocardial scar will be merged with 3D electroanatomical mapping (EAM) prior to the ablation to allow for readily localization and characterization of VT substrates and potential re-entry circuits to be ablated. This is done with the intent to limit the repeated number of inductions and prolonged point-by-point voltage mapping that often result in hemodynamic instability.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients with moderate to severe RV dysfunction diagnosed on most recent imaging (echo/c-MRI).
* Patients with must have undergone the imaging (c-MRI and/or CT) required for the investigational VT approach to qualify for participation.
Exclusion Criteria
* Patients for whom an informed consent cannot be obtained.
* Patients who are found to be pregnant using detection of human chorionic gonadotropin (hcg) as done as part of standard of care, will be excluded.
