An interventional study of NOGA TM probe in Myocardial Infarction, sponsored by University Hospital, Toulouse. Completed at 1 site in France. Open to participants aged 18 Years to 85 Years. Per ClinicalTrials.gov, last updated 2026-06-01.

Despite a decrease in voltage amplitude in post-infarction scar areas, greater voltage amplitudes are sometimes observed at the time of local extrasystoles mechanically induced by catheters.
However, no study has investigated whether these electrical changes are associated with mechanical changes in local contractility.
However, the voltage is closely correlated to the local contractile function as evidenced by the use of the NOGA system.
2,744 studies on the registry are indexed under Myocardial Infarction; 418 are open to participants now.
This study's enrollment of 10 is below the median of 148 across 1,595 interventional studies indexed under Myocardial Infarction.

- Patients who should undergo ventricular tachycardia (VT) ablation after a myocardial infarction according to current recommendations, namely: patients with ischemic heart disease (ICD) and with episodes of sustained ventricular tachycardia responsible for internal electric shocks by the implantable automatic defibrillator (ICD) (grade IB recommendation)

Exclusion Criteria:
Device: NOGA TM probe
Each subject will be his own witness since the linear local shortening (LLS) will be measured successively in all patients before, then after stimulation of the scar zone (comparison of LLS measured in sinus rhythm then during stimulation in the scar zone for each patient. Each subject being his own witness and the two recordings being made a few minutes apart, during the same procedure.
Evolution of LLS (linear local shortening) via the NOGATM system in percentage
Study the change in percentage of LLS during stimulation in a post-infarction scar zone identified by voltage mapping of the left ventricle with the NOGA system, compared to LLS in the same zone measured in atrial stimulation
Time frame: 1month
Evolution of global systolic function: left ventricular ejection fraction
Compare the left ventricular ejection fraction (in percentage) during stimulation in a scar area compared to a normal rhythm
Time frame: 1month
Evolution of the global systolic function: integral time velocity under aortic Translation results Evolution of the global systolic function: integral time velocity under aortic
Compare the integral time velocity under aortic (in centimeter) during stimulation in a scar area compared to a normal rhythm
Time frame: 1month
Evolution of the global systolic function: strain longitudinal global
Compare the strain longitudinal global(in percentage) during stimulation in a scar area compared to a normal rhythm
Time frame: 1month
