ABSTRACT
Objective To investigate the safety of left atrial appendage occlusion by silk thread ligation during open heart op‐eration in patients with rheumatic atrial fibrillation ,and to evaluate its effectiveness for prevention of cerebral embolism .Methods From April 2012 to March 2014 ,129 patients with rheumatic atrial fibrillation were undergone mitral valve replacement and left at‐rial appendage occlusion by ligation using two silk threads from the outside of the heart (ligation group) .The indexes related to the operation ,postoperative complications incidence ,and cerebral embolism incidence during the follow‐up period of ligation group were compared with the indexes of another 129 patients without ligation of left atrial appendage over the same period (control group) . Results The operation time ,the cardiopulmonary bypass time ,the clamp time ,the intensive care unit stay time ,the postoperative hospitalization time in ligation group were (235 ± 50)min ,(88 ± 24)min ,(57 ± 16)min ,(26 .5 ± 9 .3)h and (12 .4 ± 7 .5)d respective‐ly ,and significant difference was not found compared with control group (P>0 .05) .The thoracotomy for hemostasis(1 cases) ,low cardiac output syndrome(2 cases) ,acute renal failure(2 cases) ,pulmonary infection(3 cases) ,sternal wound dehiscence(2 cases) and other complications in ligation group had no significant difference ,compared with control group(P>0 .05);2 cases died in liga‐tion group ,3 patients died in control group ,the differences had no statistical significance(P>0 .05) .No cerebral embolism occurred in ligation group with 127 patients following‐up (23 .6 ± 11 .3) months ,but 5 patients suffered from cerebral embolism in control group with 126 patients following‐up (22 .9 ± 12 .1) months ,the difference had statistical significance(P<0 .05) .Conclusion Left atrial appendage occlusion by silk thread ligation during open heart operation in patients with rheumatic atrial fibrillation is simple and safe ,can reduce cerebral embolism incidence .
