Selective Angiography Using the Radiofrequency Catheter: An Alternative Technique for Mapping and Ablation in the Aortic Cusps

Abstract

Selective angiography through a cooled-tip radiofrequency ablation catheter is feasible to assess relation of coronary ostia and ablation site when ablation in aortic cusps. It allows continuous real-time assessment of this relation, avoids the need for additional vascular accesses and no complications occurred in our series.

Ablation with zero‐fluoroscopy of premature ventricular complexes from aortic sinus cusps: A single‐center experience

“…12 In addition, contrast injection through the ablation catheter has been proposed as a tool to visualize CAO, but the low flow of injected contrast limits the accuracy of CAO distance estimations. 13 The use of ICE to guide ASC-PVC ablation, as in the present study, resolves the problem of evaluating the distance from the catheter tip to ostia. 3D integration of the ICE image in the EAM system and real-time monitoring of the relationship of catheter tip to CA ostia offers a comprehensive approach that does not require CC.…”

Radiofrequency ablation of an atypical left accessory pathway from the left coronary cusp

“…Importantly, prior to the RF application, selective angiography through a cooled-tip catheter can be performed in order to avoid collateral damage to nearby coronary arteries. 15…”

Analysis of reported cases of left main coronary artery injury during catheter ablation: In search of a pattern

“…ICE is also used to guide and monitor electrode position during RF ablation in subvalvular LVOT . An alternative method to control the distance from a catheter tip to a coronary ostium during ablation in the Valsalva sinuses, not requiring additional vascular access, has been proposed . The authors used the lumen of a cooled‐tip catheter to perform repeat angiography for real‐time assessment of its relation to a coronary artery.…”
