Intra-atrial endothelial lesion resulting from transseptal puncture for catheter ablation of atrial fibrillation
نویسندگان
چکیده
Thromboembolic events are known complications of left atrial ablation therapy. We describe a complication which may also lead to systemic thromboembolism that has not been reported so far: the formation of a moving structure attached to the fossa ovalis after an attempted transseptal puncture in a 66-year old patient with symptomatic paroxysmal atrial fibrillation.

Optimal Transseptal Puncture Location for Robot-Assisted Left Atrial Catheter Ablation
BACKGROUND The preferred method of treatment for atrial fibrillation (AF) is by catheter ablation, in which a catheter is guided into the left atrium through a transseptal puncture. However, the transseptal puncture constrains the catheter, thereby limiting its manoeuvrability and increasing the difficulty in reaching various locations in the left atrium. In this paper, we address the problem o...
متن کاملDouble Transseptal Puncture for Catheter Ablation of Atrial Fibrillation: Safety of the Technique and Its Use in the Outpatient Setting
Introduction. For pulmonary vein isolation in patients with atrial fibrillation (AF), some centers use the double transseptal puncture technique for catheter access in order to facilitate catheter manipulation within the left atrium. However, no safety data has so far been published using this approach. Method. 269 ablation procedures were performed in 243 patients (mean age 56.6 ± 9.3 years, 7...
متن کاملECG findings of acute myocardial infarction and atrioventricular block during a transseptal procedure for left atrial ablation.
We report on a patient with transient atrioventricular block and ST-segment elevation mimicking the ECG of myocardial infarction during transseptal puncture for radiofrequency catheter ablation of atrial fibrillation. Symptoms and EGG findings resolved spontaneously. A neurally-mediated mechanism, activated by the mechanical effects of the transseptal puncture on the interatrial septum and lead...
متن کاملST-segment elevation and ventricular fibrillation shortly after transseptal puncture for left atrial catheter ablation
A 47-year-old man with drug-resistant paroxysmal atrial fibrillation underwent left atrial (LA) catheter ablation. After sheaths were inserted into the LA using the Brockenbrough method, he complained of angina and developed ST-segment elevation in the II, III, aVF, V5, and V6 leads. Ventricular fibrillation (VF) occurred followed by ventricular tachycardia. The VF was successfully treated with...
متن کاملThe change in the fluoroscopy-guided transseptal puncture site and difficult punctures in catheter ablation of recurrent atrial fibrillation.
AIMS A second procedure for recurrent atrial fibrillation (AF) may be associated with the need for a different positioning of the puncture site and may increase the difficulty and complications. This study investigated whether the transseptal puncture site changed and whether the difficult punctures increased in the patients who received a repeat ablation procedure for recurrent AF. METHODS A...
