Abstract
Purpose: Left atrial appendage (LAA) isolation is an effective surgical treatment for decreasing thromboembolic risk. We sought to evaluate the short-term effect of minimally invasive surgery with LAA excision on left atrial dynamic and endocrine function in atrial fibrillation (AF) patients.
Methods: A total of 52 patients with paroxysmal AF undergoing minimally invasive surgery with LAA excision in Anzhen Hospital from October 2012 to June 2014 were enrolled in the study. The natriuretic peptide plasma level was determined by enzyme-linked immunosorbent assay (ELISA), and left atrial dynamic function was measured preprocedure by real-time three-dimensional echocardiography and postprocedure after 7 days and 3 months.
Results: With the exception of six recurrences, 88.5% (46/52) of the patients were prospectively followed over 3 months in terms of their sinus rhythm postprocedure. No severe operative complications or embolism events occurred within those 3 months. Echocardiography showed a 3–6% decrease in left atrial volume postprocedure, and dynamic function was largely restored by 3 months. There was no significant change in natriuretic peptide levels, although a slight decrease was detected 7 days postprocedure, which gradually recovered by 3 months (P = 0.350).
Conclusions: There are no significant differences in left atrial dynamics and natriuretic peptide secretion in AF patients after minimally invasive surgery with LAA excision.
