CARTO-assisted bipolar radiofrequency ablation for the treatment of
refractory ventricular tachycardia associated with ventricular aneurysm:
A case report
Introduction: Evidence for the effectiveness of surgical
electrophysiological therapy for malignant ventricular tachycardia (VT)
after myocardial infarction is lacking. Methods and Results: We report a
case of a 50-year-old man with VT caused by left ventricular aneurysm
(LVA). Unipolar radiofrequency ablation (RFCA) failed to treat VT.
Nonetheless, bipolar RFCA forcep guided by CARTO mapping was used to
ablate the LVA and peripheral myocardium during traditional surgery.
There were no postoperative complications, and 1-year follow-up showed
no malignant VT occurred in 24-hours. Conclusion: Bipolar RFCA assisted
by CARTO mapping was an effective surgical electrophysiological therapy
for refractory VT caused by LVA.
