Nonalcoholic Steatohepatitis is Associated with Cardiac Remodeling and Dysfunction

Preliminary data suggest that nonalcoholic fatty liver disease is associated with early heart failure (HF). However, whether nonalcoholic steatohepatitis (NASH) is directly associated with echocardiographic changes in cardiac structure or function remains unknown.

Advanced Imaging Techniques for Mitral Regurgitation

Mitral regurgitation (MR) is one of the most commonly encountered valvular lesions in clinical practice. MR can be either primary (degenerative) or secondary (functional) depending on the etiology of MR and the pathology of the mitral valve (MV). Echocardiography is the primary diagnostic tool for MR and is key in determining this etiology as well as MR severity. While clinicians usually turn to 2 Dimensional echocardiography as first-line imaging, 3 Dimensional echocardiography (3DE) has continually shown to be superior in terms of describing MV anatomy and pathology. This review article elaborates on 3DE techniques, modalities, and advances in software. Furthermore, the article demonstrates how 3DE has reformed MR evaluation and has played a vital role in determining patient management.

DIFFERENTIAL EFFECTS OF DOBUTAMINE AND EXERCISE ON LEFT VENTRICULAR VOLUMES DURING STRESS ECHOCARDIOGRAPHY

Stress echocardiography is deemed diagnostic with achievement of target heart rate (HR) (> 85% maximum predicted) or double product (DP) for exercise (ESE) and dobutamine (DSE). However both modalities affect the left ventricle (LV) differently. Exercise increases HR physiologically to increase
