Why the study?
Does radiofrequency current isthmus ablation using an 8-mm tip electrode cause damage to the right coronary artery in a patient with common atrial flutter?
Does radiofrequency current isthmus ablation using an 8-mm tip electrode cause damage to the right coronary artery in a patient with common atrial flutter?
RF isthmus ablation with an 8-mm tip electrode may cause intramural hemorrhage in the adjacent right coronary artery without apparent injury to other arterial layers.
May signal intramural RCA hemorrhage risk with 8-mm RF ablation; single case leaves open clinical relevance and need for confirmation.
WEISS, C., et al. : Can Radiofrequency Current Isthmus Ablation Damage the Right Coronary Artery? Histopathological Findings Following the Use of a Long (8 mm) Tip Electrode. This report describes the histopathological findings following successful RF isthmus ablation for common atrial flutter in a 68‐years‐old man using a long 8‐mm tip ablation catheter. No acute complication was observed. The patient died 3 weeks after ablation due to severe heart failure and consecutive pneumonia. Lesion width (1.0 and 2.4 cm) and depth (0.4 and 0.8 cm) was measured. The right coronary artery showed an intramural hemorrhage adjacent to the side of the lesion. However, despite this finding no apparent injury of other layers of the coronary artery was detectable.
