The Relationship of Left Atrial Size of Rheumatic Heart Disease to Myocardial Pathology and Its Clinical Implications / 第二军医大学学报

The relation between left atrial (LA) size and myocardial pathological changes, and clinical implications were studied in 25 patients with- rheumatic mitral stenosis. The results showed that LA size was significantly correlated with pathological severity of myocardium (P 100 ml/m2 and accompanied by moderate or severe pathological changes easily suffered from Af (P200ml/m2 and severe pathological changes. The results suggest that occurence of Af may be predicated based on the LA volume and Af cardioversion should be selectively performed to obtain better results.
