Echocardiographic Assessment of Diastolic Function in Heart Failure

Echocardiography remains the cornerstone for non-invasive evaluation of left ventricular diastolic function in patients with heart failure. By combining conventional Doppler‐derived transmitral flow velocities (E and A waves), deceleration time and pulmonary venous flow patterns with tissue Doppler imaging of myocardial relaxation (e′ velocity), clinicians can infer left atrial pressure and chamber compliance. The ratio of early transmitral flow to early diastolic annular velocity (E/e′) has emerged as a practical surrogate for filling pressures. Structural markers such as left atrial volume index and tricuspid regurgitation velocity further refine the assessment. Recent guidelines advocate an integrated, multi-parameter algorithm to grade diastolic dysfunction from normal filling (grade 0) through impaired relaxation (grade 1), pseudonormal filling (grade 2) to restrictive physiology (grade 3). Beyond conventional measures, deformation imaging via speckle tracking echocardiography provides strain and strain-rate indices that detect subtle myocardial stiffness and predict adverse outcomes. In heart failure with preserved ejection fraction, echocardiographic assessment identifies elevated filling pressures during stress or exercise, guiding therapeutic decisions. The global significance of accurate diastolic evaluation lies in its ability to stratify risk, monitor response to therapy and inform prognosis across diverse patient populations and healthcare settings.

Technical terms

Diastolic dysfunction: Impaired ventricular relaxation or increased stiffness leading to abnormal filling and elevated pressures.

Global longitudinal strain (GLS): Measure of myocardial deformation representing percentage change in length of the left ventricle during systole and diastole.

Speckle tracking echocardiography (STE): Imaging technique that tracks natural acoustic markers (“speckles”) to quantify myocardial strain and strain rate.

Tissue Doppler imaging (TDI): Ultrasound method measuring velocity of myocardial motion, particularly early diastolic (e′) and late diastolic (a′) annular velocities.
