Preferential Locations for Critical Reentry Circuit Sites Causing Ventricular Tachycardia After Inferior Wall Myocardial Infarction
Why the study?
What are the preferential locations for reentry circuit isthmus regions in chronic inferior wall infarctions causing VT?
Population

Implication
May inform basal-focused mapping in post-inferior MI VT ablation; extends localization data but requires prospective validation.

Intervention
Catheter mapping and radiofrequency (RF) catheter ablation

Outcome
Location of reentry circuit isthmus sitessurrogate
In patients with VT after inferior wall MI, reentry circuit isthmus zones are predominantly located near the base of the left ventricle, suggesting the mitral annulus plays a role in defining circuit margins.
