Key result
Extensive RVOT radiofrequency ablation linked to asymptomatic mid-LAD occlusion in one patient.
Why the study?
Damage to adjacent endo- and epicardial structures during radiofrequency ablation in certain locations is not well described.
Case Report (n=1)
Radiofrequency ablation of the right ventricular outflow tract can cause collateral damage to adjacent structures, such as the left anterior descending coronary artery, highlighting the need for careful evaluation.
Alerts to rare LAD injury risk after RVOT ablation; leaves open incidence and surveillance needs in larger series.
INTRODUCTION: Radiofrequency ablation has become a standard procedure in the treatment of ventricular arrhythmias. The success rate varies according to the etiology and the presence or absence of underlying structural heart disease, while complication rates are relatively low. METHODS: To describe the damage in neighboring structures during the ablation in certain locations. RESULTS: We present a patient who underwent a radiofrequency ablation of sustained monomorphic ventricular tachycadia at the inferior and anterior part of the right ventricular outflow tract, at the insertion of the right ventricle to the left ventricle. Extensive ablation resulted in an asymptomatic occlusion of the mid segment of the left descending coronary artery. CONCLUSION: Creation of deeper and broader lesions with current catheter technologies can result in damage of the adjacent endo- and epicardial structures. Careful evaluation of the area of interest prior to and after the ablation should therefore be mandatory.

Dilling‐Boer et al. (2015) conducted a case report in Sustained monomorphic ventricular tachycardia (n=1). Radiofrequency ablation was evaluated on Damage in neighboring structures. Extensive radiofrequency ablation of the right ventricular outflow tract resulted in an asymptomatic occlusion of the mid segment of the left anterior descending coronary artery in one patient.
