title: The association between mean platelet volume and spontaneous echocardiographic contrast or left atrial thrombus in patients with mitral stenosis.
abstract: Although the role of platelet activation has been debated in patients with mitral stenosis (MS) and spontaneous echocardiographic contrast (SEC), data on differences in mean platelet volume (MPV) according to the presence of SEC/left atrial thrombus and the rhythm status are lacking. In this study, MPV was analyzed in patients with MS according to the presence of SEC/left atrial thrombus.
  
  
  
  Between January 2005 and March 2014, 188 symptomatic patients having moderate or severe MS (mean age, 45.0±11.7 years; female, 81.4%) with favorable valve morphology for percutaneous mitral balloon valvuloplasty (PMBV) and underwent a transesophageal echocardiogram to assess the eligibility for PMBV were retrospectively enrolled in the study. The relation between MPV and echocardiographic thromboembolic risk factors were evaluated. Independent predictors of SEC/left atrial thrombus presence were determined by multiple logistic regression analyses.
  
  
  
  Among all patients, MPV did not differ according to the rhythm status or the presence of SEC/left atrial thrombus (p>0.05). Also, MPV did not vary according to the gender and presence of prior stroke in both atrial fibrillation and sinus rhythm groups (p>0.05). In correlation analysis, MPV did not show any significant correlation with the echocardiographic thrombus predictors (p>0.05).
  
  
  
  Using MPV with echocardiographic and clinical thrombus risk determinants for predicting individual thromboembolism risk in MS is debatable according to our results.
