diastolic filling pattern
The characteristic pattern of left ventricular filling during diastole, assessed by Doppler echocardiography to evaluate diastolic function.
Full Definition
Diastolic filling pattern refers to the specific characteristics of blood flow into the left ventricle during diastole, as measured by pulsed-wave Doppler at the mitral valve tips. The pattern includes early diastolic filling (E wave) and late diastolic filling from atrial contraction (A wave). Normal patterns show E > A with appropriate deceleration time. Abnormal patterns include impaired relaxation (E < A), pseudonormal (E ≈ A with prolonged deceleration), and restrictive (E >> A with shortened deceleration time). These patterns correlate with diastolic dysfunction severity and help guide clinical management. Additional parameters like E/e' ratio and left atrial volume provide further insight into filling pressures.
Usage
Usage note: Should be interpreted in conjunction with tissue Doppler and other diastolic parameters.
