Echocardiographic Assessment of Ventricular Function in Heart Failure

Echocardiography serves as the cornerstone for non-invasive evaluation of ventricular performance in patients with heart failure. By combining two-dimensional imaging, Doppler flow assessment and advanced deformation analysis, it offers a comprehensive appraisal of both systolic and diastolic function. Left ventricular ejection fraction (LVEF) remains the most widely used index of systolic performance, yet it is limited by geometric assumptions and relative insensitivity to subtle myocardial impairment. Speckle tracking echocardiography (STE) and global longitudinal strain (GLS) have emerged to unmask early systolic dysfunction, even in the setting of preserved LVEF. Diastolic function is characterised using transmitral and pulmonary venous Doppler, mitral inflow parameters and tissue Doppler imaging to derive left ventricular filling pressures. Right ventricular function and atrial mechanics are increasingly recognised as integral to prognosis, with tricuspid annular plane systolic excursion (TAPSE), right ventricular strain and atrial reservoir strain providing additional prognostic granularity. Multimodal echocardiographic protocols, integrating volumetric measurements with flow-based and deformation markers, now underpin risk stratification, guide therapeutic decision-making and facilitate monitoring of device therapies in heart failure management.

Research from Nature Portfolio

Innovative in vitro modelling has advanced understanding of atrioventricular interactions in heart failure. A flexible silicone left atrium, mechanically matched to biological tissue, was incorporated into a mock circulatory loop to replicate physiological pulmonary venous and ventricular dynamics. By variably adjusting atrial compliance, investigators reproduced realistic pressure–flow relationships and pressure–volume loops, validating non-invasive surrogates of filling pressures. This platform promises to refine preclinical evaluation of devices and interventions targeting left heart haemodynamics. Separately, non-invasive imaging research has probed mechanisms of left ventricular dysfunction in pulmonary arterial hypertension. Comparison of pulmonary vein area and flow by cardiac magnetic resonance with echocardiographic filling indices revealed that underfilling, rather than intrinsic myocardial disease, predominates in this population. Pulmonary vein metrics demonstrated strong associations with mitral E/e′ ratio and atrial volumes, suggesting a novel imaging marker for differentiating underfilled from pressure-overloaded ventricles. Both studies highlight the synergy between advanced modelling and multimodal imaging to enhance diagnostic precision.

The graph below shows the total number of articles in echocardiographic assessment of ventricular function in heart failure across all publications each year (not limited to Nature Index journals).

Technical terms

Left ventricular ejection fraction (LVEF): The percentage of end-diastolic volume ejected during systole, a conventional measure of systolic function.

Speckle tracking echocardiography (STE): An ultrasound-based technique that tracks natural acoustic markers to quantify myocardial deformation.

Global longitudinal strain (GLS): A measure of myocardial shortening along the long axis, reflecting subclinical systolic impairment.

Left ventricular outflow tract velocity time integral (LVOT VTI): The Doppler-derived distance travelled by blood in the outflow tract per heartbeat, serving as a surrogate for stroke volume.

Left ventricular filling pressure (LVFP): The pressure within the ventricle during diastole, indicative of preload and diastolic function.
