Right coronary artery wall edema provoked by cavotricuspid isthmus radiofrequency ablation

چکیده
Introduction Acute coronary stenosis has been reported as a rare but potentially serious complication of cavotricuspid isthmus (CTI) ablation. Various causes of the stenosis have been reported (thrombus, coronary spasm), but cause is often unknown. Most of the cases receive coronary intervention regardless of the cause. We present a case of “temporary edema” of the coronary artery wall provoked by CTI radiofrequency (RF) ablation.

Acute Right Coronary artery Occlusion During Cooled-Tip Radiofrequency Ablation of the Cavotricuspid Isthmus
Cooled-tip radiofrequencycatheter ablation of the cavotricuspid isthmus, performed after pulmonary vein isolation, resulted in acute occlusion of the posterolateral branch of the right coronary artery in a 49-year-old male with previously known right coronary artery disease. The occlusion was successfully stented. It is conceivable that previously diseased coronary arteries are more prone to be...
متن کاملRadiofrequency catheter ablation of common-type atrial flutter guided by conventional versus electroanatomical mapping.
Radiofrequency catheter (RF) ablation aiming the complete conduction block of the cavotricuspid isthmus has become treatment of choice for common type atrial flutter. Different approaches to guide the ablation procedure are used. For the conventional approach multipolar catheters in the right atrium and in the coronary sinus are required to detect the induction of conduction block via the isthm...

متن کاملThe inferior right atrial isthmus: further architectural insights for current and coming ablation technologies.
BACKGROUND Although linear ablation of the right atrial isthmus in patients with isthmus-dependent atrial flutter can be highly successful, recurrences and complications occur in some patients. Our study provides further morphological details for a better understanding of the structure of the isthmus. METHODS AND RESULTS We examined the isthmic area in 30 heart specimens by dissection, histol...
متن کاملEffects of cavotricuspid isthmus ablation on atrioventricular node electrophysiology in patients with typical atrial flutter.
BACKGROUND The atrial musculature in the cavotricuspid isthmus is a part of posterior inputs to the AV node. In patients with typical atrial flutter, effects of radiofrequency ablation of this isthmus on AV node conduction are still unknown. METHODS AND RESULTS This study included 16 patients with clinically documented typical atrial flutter. Group 1 had 8 patients without and group 2 had 8 p...
