In a follow-up study, 77 patients with predominant mitral stenosis were examined to investigate the role of left atrial (LA) enlargement in LA thrombi. Fifteen (19.4%) patients had LA thrombi. Of these, 2 (13.3%) were in sinus rhythm and 13 (86.7%) in atrial fibrillation. Fourteen (93.3%) of the patients with LA thrombi had an LA size > or = 4.8 cm. Only(More)
