COVID-19 has rapidly spread around the world and threatened global health. Although this disease mainly affects the respiratory system, there is increasing evidence that SARS-CoV-2 also has effects on the cardiovascular system. Echocardiography is a valuable tool in the assessment of cardiovascular disease. It is cost-effective, widely available and provides information that can influence management. Given the risk of personnel infection and equipment contamination during echocardiography, leading world societies have recommended performing echocardiography only when a clinical benefit is likely, favouring focused evaluations and using smaller portable equipment. In the past months, multiple reports have described a wide pattern of echocardiographic abnormalities in patients with COVID-19. This review summarised these findings and discussed the possible mechanisms involved.

Changes in LV ejection dynamics and septal base function account in part for the acute relief of LVOT gradient after NSRT. The long-term relief of obstruction is dependent on remodeling of LVOT as well as the changes in LV ejection.

Galectin-3 is elevated in diabetic patients with mdEF, and is associated with a diminished GLS. GLS could be an early marker of left ventricular dysfunction as well as evidence of diabetic cardiomyopathy.
