title: Left atrial thrombosis in pregnant women with mitral stenosis and sinus rhythm.
abstract: OBJECTIVE
  The purpose of this study was to describe pregnant patients with mitral stenosis who had intracardiac thrombosis in the absence of atrial fibrillation.
  
  
  METHODS
  We reviewed the clinical course of 3 pregnant women with severe mitral stenosis and normal sinus rhythm who had clinically significant intracardiac thrombosis.
  
  
  RESULTS
  The first patient was examined at 21 weeks of gestation with embolic stroke that was the result of left atrial thrombus. A second patient was found to have a large left atrial thrombus that prevented the performance of balloon valvuloplasty. The third patient had left atrial clot that partially occluded the mitral valve orifice and led to the development of pulmonary edema that resulted in an emergent cesarean delivery and anoxic brain injury in the newborn infant.
  
  
  CONCLUSIONS
  Pregnant patients with mitral stenosis in normal sinus rhythm can experience thromboembolic events that can be detrimental to both the mother and the fetus. Anticoagulation therefore should be strongly considered in this group.
