Usefulness of Left Atrial Volume for the Differentiation of Normal from Pseudonormal Diastolic Function Pattern in Patients on Hemodialysis

Enlargement of LA reflects the chronicity and burden of left ventricular diastolic dysfunction in stable patients undergoing HD with early to atrial transmitral velocity ratio apparently normal on conventional Doppler echocardiography. LAVi is a practical and useful parameter to discriminate normal from pseudonormal mitral flow.
