Key result

Catheter ablation with a single 20-second application of radiofrequency current, guided by an endocardial map of slow conduction, successfully treated recurrent ventricular tachycardia in one patient.

Why the study?

Does catheter ablation with radiofrequency current guided by an endocardial map successfully treat recurrent ventricular tachycardia in a patient with prior myocardial infarction?

Population

68-year-old male patient with a history of myocardial infarction and recurrent ventricular tachycardia

Implication

Supports map-guided short RF ablation feasibility in post-MI VT; hypothesis-generating from one case, needs prospective validation.

Key Points

To report the successful treatment of ventricular tachycardia in a patient with a history of myocardial infarction using radiofrequency ablation.
Single 20-second transcatheter application of radiofrequency current performed after creating an endocardial map of the slow conduction area.
Mapping identified a 2 cm area along the lower left ventricular septum associated with tachycardia initiation and maintenance.
Successful ablation of the ventricular tachycardia was achieved with a 20-second application.
The targeted area was confirmed to be critically linked to the tachycardia, leading to successful outcomes.

Population

68-year-old male patient with a history of myocardial infarction and recurrent ventricular tachycardia

Intervention

Single 20-second transcatheter application of radiofrequency current guided by an endocardial map of an area of slow conduction

Outcome

Successful treatment of ventricular tachycardia

This case demonstrates the feasibility of using an endocardial map of slow conduction to guide successful radiofrequency catheter ablation of ventricular tachycardia.
