Abstract
Objective To investigate the impact of left atrial sphericity(LASP)and functional mitral regurgitation on the maintenance of sinus rhythm after radiofrequency catheter ablation(RFCA)in patients with atrial fibrillation(AF),and to evaluate their correlation with procedural outcomes.Methods A total of 105 patients undergoing initial RFCA treatment for AF were enrolled,and categorized into a non-recurrence group(66 cases)and a recurrence group(39 cases)based on post-operative follow-up results.General clinical data,and echocardiographic and left atrial CT angiography related parameters[including left atrial anteroposterior diameter,LVEF,mitral regurgitation area(MRA),left atrial volume,LASP,etc.]were collected,and made intergroup comparisons.Univariate and multivariate Cox regression analyses were used to identify factors associated with AF recurrence.Results The left atrial anteroposterior diameter,mitral regurgitation rate,MRA,left atrial volume,and LASP were all significantly higher in the recurrence group compared to the non-recurrence group(all P＜0.05).Cox regression analysis indicated that LASP,mitral regurgitation,and MRA were significantly associated with post-operative recurrence(all P＜0.05).Conclusion LASP and mitral regurgitation are closely associated with AF recurrence after RFCA,and could serve as reference indicators for predicting post-operative recurrence.关键词
