Correlation Between Transmitral Early and Late Diastolic Velocities Ratio and Ratio of Medial Mitral Annular Early and Late Tissue Doppler Velocities

Echocardiography is now the most commonly used noninvasive tool for the assessment of cardiac anatomy and function. In addition to commonly established roles such as confirming the diagnosis, etiologic work-up, complication screening, and disease monitoring, echocardiography plays an important clinical role in prognostic assessment.
