Abstract:
Objective:To analyze the safety and efficacy of left atrial appendage closure(LAAC)with Watchman in patients ≥85 years with atrial fibrillation(AF).Methods:515 elderly patients with atrial fibrillation, including 73 patients aged 85 years or older(85~91), who had undergone Watchman LAAC at Zhoupu Hospital affiliated to Shanghai Health Medical College from August 2016 to December 2020, were retrospectively analyzed.Of those ≥85 years, 44(60.3%)with transesophageal echocardiography records were assigned to the elderly group.Fifty-three patients aged 60 to 65 were selected as the control group.Differences in baseline data, intraoperative conditions, antithrombotic treatment plans and 1-year follow-up prognosis were compared between the two groups.Results:Compared with the control group, there was no difference in AF types, history of ischemic stroke/transient ischaemic attack(all P>0.05), but there were higher incidences of coronary heart disease and renal insufficiency, more severe heart failure, higher CHA 2DS 2-VASC(6.0±1.5 vs.3.6±1.5), HAS-BLED(3.2±1.2 vs.2.3±1.3)scores( t values were 7.682 and 3.871, respectively, P<0.05), and a lower one-stop surgery rate(6 cases or 13.6% vs. 27 cases or 50.9%, χ2=10.517, P<0.05)in the advanced age group.There was no difference in the diameter of the Watchman device, rate of device replacement, compression percentage and residual flow between the two groups during the perioperative period.The incidences of device-related thrombosis were 4.5%(2/44)and 3.8%(2/53)for the advanced age group and the control group, respectively, but the difference was not statistically significant( P>0.05). During the 12-month follow-up, there were no cases of ischemic stroke or intracerebral hemorrhage.Three died of heart failure and 1 died of cancer. Conclusions:LAAC with Watchman is safe and effective for patients over 85 years with AF, but the decision on the procedure should be based on careful assessment of patients' cardiac and renal function and general health.
