Abstract:
Objective:To investigate the association between age and cardiac tamponade after radiofrequency ablation of atrial fibrillation(RAAF).Methods:Clinical data of patients undergone de novo AF ablation procedures at Beijing Anzhen Hospital from January 2013 to December 2016 were retrospectively collected.Patients were divided into an elderly group(age ≥60 years)and a non-elderly group(age <60 years). Logistic regression analyses were used to evaluate the association between old age and the risk of cardiac tamponade complicating RAAF.Results:A total of 5 313 patients were involved in this study, including 41 patients(0.77%)with cardiac tamponade.The proportion of cardiac tamponade was higher in the elderly group than in the non-elderly group(1.1% or 32/2 950 vs.0.4% or 9/2 363, χ2=8.489, P=0.004). One patient with cardiac tamponade in the elderly group required immediate surgical repair whereas none in the non-elderly group did.No patient died in hospital.Multivariate Logistic regression analysis showed that the risk of cardiac tamponade increased in the elderly group, compared with the non-elderly group( OR=2.570, 95% CI: 1.190-5.570, P=0.017). Stratified analysis revealed that among females and patients with oral anticoagulants, left atrium dimension < 40 mm or procedure duration≥ 120 min in the elderly group carried a higher risk of cardiac tamponade than those in the non-elderly group( OR=1.011, 2.914, 3.922 and 3.244, P<0.05). Conclusions:Old age(age ≥60 years)is an independent risk factor for cardiac tamponade complicating RAAF.
