Abstract
BackgroundThree-dimensional echocardiography (3DE) with real-time volumetric imaging can be a vital modality in clinical practice. Despite its potential, it remains underutilized in the acute care setting.Case presentationWe present two cases describing the use of 3DE in the emergency department (ED) for acute heart failure (AHF) and discuss the potential benefits of routine use in acute care settings.ConclusionsThree-dimensional echocardiography offers unique information as it relates to cardiac structure and function, and can be valuable for diagnosis and clinical decision-making in the ED.
Highlights
Three-dimensional echocardiography (3DE) with real-time volumetric imaging can be a vital modality in clinical practice
When combined with 3DE-derived LV. Volumes, it can be an effective noninvasive modality to help determine if such patients need an acute coronary intervention [3]. Why might this be? Along with volume, LV shape is a useful parameter to assess LV dysfunction induced by ischemia, with the ventricle becoming more globular as LV function deteriorates
In addition to Sphericity index (SI) being the most sensitive (100%) and specific (90%) indicator to early LV remodeling after myocardial infarction (MI) [6], it can be essential in the acute ischemic setting as regional and global sphericity indices are increased in patients with regional wall motion abnormalities (RWMA) and dilated cardiomyopathy [7]
Summary
Three-dimensional echocardiography (3DE) with real-time volumetric imaging can be a vital modality in clinical practice. Given its superiority to two-dimensional echocardiography (2DE) in calculating left ventricular volumes and ejection fraction (EF) [2], there remains much potential for use in acute heart conditions. We present two cases describing the use of 3DE in the emergency department (ED) in acute heart failure (AHF), with images obtained prior to therapeutic intervention.
