Catheter Ablation of Mitral Isthmus Ventricular Tachycardia Using Electroanatomically Guided Linear Lesions
Key result
Electroanatomically guided linear lesion placement successfully eliminated mitral isthmus ventricular tachycardia in a patient with a wide isthmus after focal ablation had failed.
Why the study?
Does catheter ablation using electroanatomically guided linear lesions eliminate tachycardia in patients with mitral isthmus ventricular tachycardia?

Structured PICO
Does catheter ablation using electroanatomically guided linear lesions eliminate tachycardia in patients with mitral isthmus ventricular tachycardia?
P
Population
1 patient with mitral isthmus ventricular tachycardia and a wide tachycardia isthmus, with previously unsuccessful focal ablation
I
Intervention
Catheter ablation using electroanatomically guided linear lesions from the edge of the inferior infarct to the base of the mitral valve
O
Outcome
Elimination of tachycardia
Electroanatomic mapping can guide the placement of linear lesions to successfully eliminate tachycardia in patients with mitral isthmus VT and a wide isthmus.
Cite This Study
Friedman et al. (2000) conducted a case report in Mitral isthmus ventricular tachycardia (n=1). Electroanatomically guided linear lesion catheter ablation vs. Focal isthmus ablation (prior failed attempt) was evaluated on Elimination of tachycardia. Electroanatomically guided linear lesion placement successfully eliminated mitral isthmus ventricular tachycardia in a patient with a wide isthmus after focal ablation had failed.
