Abstract:
Objective To observation the changes of left atrium and pulmonary veins(PV)in patients with atrial fibrillation(AF) by transthoracic two-and three-dimensional echocardiography. Methods Transthoracic echocardiography were applied in 126 patients,which were divided into sinus rhythm(SR) group(64 cases)and AF group(62 cases),AF group were further divided into two subgroups:the paroxysmal AF and non-paroxysmal AF group.Left atrial area(LAA),left atrial volume(LAV),left atrial diameter(LAD)were measured by 2-dimensional echocardiography imaging.PV diameters were measured by three-dimensional echocardiography. Results Compared with SR group,PV diameters were significantly increased in AF group(P＜0.05).In patients with AF,PV diameters in non-paroxysmal AF group were larger than paroxysmal AF group.The four PV diameters in SR,paroxysmal AF and non-paroxysmal AF group did not show statisticant difference(P＞0.05).Compared with SR group,LAD,LAA,LAV were increased in AF group.LAD,LAA,LAV were larger in non-paroxysmal AF group than SR group and paroxysmal AF group(P＜0.05).Conclusions Left atrium and PV dilate significantly in patients with AF,transthoracic echocardiography could be a non-invasive method to observe left atrium and PV.
