Abstract:
Objective:To investigate the relationship of delayed cardiac tamponade (CT) after left atrial appendage closure (LAAC) in atrial fibrillation (AF) patients and implanted occluders and adjacent anatomical structures.Methods:This study was a retrospective study. Thirteen AF patients with LAAC complicated with delayed CT and with concurrent emergency pericardiocentesis drainage in Zhoupu Hospital, Shanghai University of Medicine & Health Sciences from August 2016 to June 2021 were selected. The follow-up time was (16±12) months. The clinical data of these patients were retrospectively analyzed, including the relationship between the left atrial appendage and pulmonary artery, vein anatomy by left atrium computed tomography angiography (CTA) before and after LAAC.Results:Thirteen patients with delayed CT were treated by pericardiocentesis and drainage after LAAC and aged (72.1±8.3) years, and 7 patients were male, Six patients received cryoablation simultaneously. The classification types of left atrial appendage included cauliflower and chicken wing types were 8 and 5 respectively. The seal plate diameter of the lobe-and-disc devices was (29.5±2.8)mm; 10 patients had cardiac CTA reviewed. The occluder was attached to pulmonary artery in 8 patients, attached to left superior pulmonary vein only in one patient, and attached to pulmonary artery and left superior pulmonary vein in one patient. The prognosis was good except one patient who died 2 days after LAAC.Conclusions:Delayed CT after LACC is closely related to the location of left atrial appendage adjacent to pulmonary artery and left superior pulmonary vein, and is related to larger occluder and anchor hook.
