Concomitant thoracoscopic surgery for solitary pulmonary nodule and atrial fibrillation.

OBJECTIVES

The incidence of both solitary pulmonary nodules (SPN) and non-valvular atrial fibrillation (NVAF) has increased over the past decade. We performed concomitant video-assisted thoracoscopic surgery with modified epicardial radiofrequency ablation procedure for NVAF and SPN resection.

METHODS

Sixteen patients (7 men, mean age 62.6 ± 11.2 years) with SPN and NVAF underwent this procedure. Of these patients, 10 had paroxysmal atrial fibrillation and 6 persistent atrial fibrillation. A modified epicardial radiofrequency ablation combined with pulmonary vein isolation, circumferential left atrial ablation, ganglionic plexus ablation and left atrial appendage resection was performed for all patients. Left pulmonary surgery was carried out subsequently.

RESULTS

The mean procedure duration was 203.1 ± 15.6 (range 177-224) min. All patients successfully underwent this procedure with no conversion to sternotomy or pacemaker implantation. Of the 16 included patients, 13 received lobectomy and 3 received wedge resection. No severe complications occurred postoperatively. The mean length of hospital stay was 9.1 ± 1.4 (range 7-11) days with a mean follow-up period of 18.7 ± 6.7 (range 8-32) months. One patient had AF recurrence 6 months postoperatively. No pulmonary vein stenosis was detected at the 3rd postoperative month. There were no deaths or thromboembolic events during follow-up.

CONCLUSIONS

This concomitant therapy proved to be safe and yielded good clinical outcomes. Therefore, it deserves to be considered as a treatment for patients with SPN and NVAF.
