Practical diastology

Figure 1 Diastolic function classification. Echocardiographic classification of diastolic dysfunction adapted for transesophageal echocardiography is shown. A: Peak late diastolic transmitral flow velocity; A dur: Duration of mitral inflow A-wave; AR dur: Peak pulmonary venous atrial reversal flow velocity duration; D: Peak diastolic pulmonary venous flow velocity; DT: Deceleration time; E: Peak early diastolic transmitral flow velocity; Em: Peak early diastolic myocardial velocity; LV: Left ventricle; S: Peak systolic pulmonary venous flow velocity; Vp: Flow propagation velocity.
