Significant Mitral Regurgitation is Protective Against Left Atrial Spontaneous Echo Contrast and Thrombus as Assessed by Transesophageal Echocardiography

This retrospective study examines whether a relationship exists between the severity of mitral regurgitation (MR) and the presence of left atrial spontaneous echo contrast and/or thrombus (SEC/THR) as assessed by transesophageal echocardiography in 427 consecutive patients. Clinical data were evaluated in 316 of these patients. Nine percent of patients with MR ≤2 + versus p p
