Aim. Evaluation of short- and mid-term (up to one year) results of aт atrial fibrillation thoracoscopic radiofrequency ablation (TRFA) combined with left atrial appendage resection.Methods. 10 patients with persistent AF were included in the study. In 5 cases surgical ablation was performed as the primary intervention and in 5 cases surgery were preceded by two unsuccessful catheter procedures. Age of the patients was 54.4 (41; 63) years, duration of arrhythmic anamnesis – 5.6 (4.8; 6.8) years, anteroposterior size of the left atrium – 4.7 (45; 51 mm), LV ejection fraction – 63 (58; 68) %. TRFA included an isolation of right and left pulmonary veins, ablation lines along the roof and base of posterior wall of the left atrium, left atrial appendage resection.Results. In all cases of TRFA exit-block from the pulmonary veins was achieved. Among 10 procedures, a stable sinus rhythm was documented in 6 patients. In the remaining 4 patients AF was observed only in one case, and the other three demonstrated atypical atrial flutter, that given us a reason to repeat catheter procedures. In three cases of left atrial flutter, catheter ablation led to sinus rhythm restoration, and in case of AF and total sclerosis of left atrium a decision to refuse RF ablation was made. Complications were presented by a single case of bilateral phrenic nerve palsy, which required plication of the diaphragm, and two spontaneously resolved pulmonary atelectasis.Conclusion. The efficacy of atrial fibrillation thoracoscopic radiofrequency ablation during the follow-up period of one year was 90% regarding selective hybrid approach (thoracoscopic + catheter procedure). Procedure safety of TRFA was much lower than that of catheter ablation: the total number of small and big complications was 30%.

Atrioesophageal Fistula

Abstract Atrioesophageal fistula (AEF) is an important complication of radiofrequency ablation (RFA). Delayed diagnosis is associated with increased morbidity and mortality. Despite the name “atrioesophageal fistula,” fistulas functionally act esophageal to atrial, which accounts for the neurologic and infectious complications. This report presents the management of a 60-year-old male patient who was admitted to the emergency department (ED) with AEF-caused gastrointestinal bleeding. The patient was operated urgently, but he had serious comorbidities and died after the operation. The aim of this case was to evaluate patients who underwent RFA, within 10 days to two months, carefully in the ED and to know the possible complications.

Successful Collaboration

Objective Transmural and contiguous ablations and a comprehensive lesion pattern are difficult to create from the surface of a beating heart but are critical to the successful treatment of persistent, isolated atrial fibrillation. A codisciplinary simultaneous epicardial (surgical) and endocardial (catheter) procedure (Convergent procedure) addresses these issues. Methods Patients with symptomatic atrial fibrillation who failed medical treatment were evaluated. Using only pericardioscopy, the surgeon performed near-complete epicardial isolation of the pulmonary veins and a “box” lesion on the posterior left atrium using unipolar radiofrequency ablation. Simultaneous endocardial catheter radiofrequency ablation completed pulmonary vein isolation, performed a mitral annular and cavotricuspid isthmus line of block, and debulked the coronary sinus. Twelve-month results for the Convergent procedure were compared with 12-month results for concomitant and pericardioscopic (stand-alone transdiaphragmatic/thoracoscopic) atrial fibrillation procedures using unipolar radiofrequency ablation. Results Sixty-five patients underwent the Convergent procedure (mean age, 62 y; mean body surface area, 2.17 m2; mean atrial fibrillation duration, 4.8 y; mean left atrial size, 5.2 cm). Ninety-two percent were in persistent or long-standing persistent atrial fibrillation. At 12 months, evaluation with 24-hour Holter monitors found 82% of patients in sinus rhythm, while only 47% of pericardioscopic and 77% of concomitant patients treated with unipolar radiofrequency ablation were in sinus rhythm. Conclusions Simultaneous epicardial and endocardial ablation improves outcomes for patients with persistent or longstanding persistent atrial fibrillation. This successful collaboration between cardiac surgeon and electrophysiologist is an important treatment option for patients with large left atriums and chronic atrial fibrillation.

Successful Isolation

Atrial fibrillation (AF) is originated from mostly from pulmonary vein (PV) foci or non-PV foci in the posterior left atrium (PLA). The present study was designed to evaluate the usefulness of a radiofrequency HOT balloon catheter (RBC) for isolation of the PLA including all PVs en masse in the patients with AF. In a total of 96 patients (75 men and 21 women; mean age 64±8 years old) with drug-resistant paroxysmal (n=63) and persistent AF(n=33), PLA including all PVs were ablated and isolated using RBC. Dragging the balloon, contiguous lesions at the roof between the superior PVs were first created, then each antrum of all PVs were ablated, and finally, contiguous lesions at the PLA between the both inferior PVs were made, while we performed monitoring esophagus temperature and phrenic nerve pacing. Electro-anatomical bipolar voltage amplitude mapping (CARTO) of the LA-PVs was performed to determine the extent of this electrical isolation after all procedure. Successful isolation of the PLA including all PVs was achieved in all of 96 cases with elimination of all the PLA and PV potentials. The mean total procedure time 133 ± 31 minutes including 32±9 minutes fluoroscopy time. Recurrences of AF were diagnosed by Holter monitoring, mobile electrocardiogram. After first session, eighty- seven (59 paroxysmal, 28 persistent) of 96 patients were free from AF without anti-arrhythmic drugs and the remaining patients could maintain sinus rhythm with anti-arrhythmic drugs except two cases with LA flutter during 11.0±4.1 months follow-up. No major complications such as cerebral embolism, PV stenosis, or phrenic nerve palsy, and LA-esophageal fistula were observed. Complete isolation of the PLA including all PVs using a RBC, is useful for the treatment of both paroxysmal and persistent AF without severe complication.
