Left Ventricular Regional Diastolic Dysfunction in Patients with First Myocardial Infarction Determined by Diastolic Motion of the Atrioventricular Plane.

Motion of the left ventricular [left ventricle (LV)] atrioventricular (AV) plane has been used to assess systolic LV function. The method has not been used properly to assess diastolic function, especially after a first myocardial infarction (MI). The diastolic function was assessed in 47 previously healthy patients with a first MI assessed by echocardiographic diastolic motion of the LV AV plane.
