Abstract :
Inferior vena cava (IVC) diameter and respirophasic variation are commonly used echocardiographic indices to estimate right
atrial pressure. While dilatation of the IVC and reduced collapsibility have traditionally been associated with elevated right
heart filling pressures, the significance of isolated IVC dilatation in the absence of raised filling pressures remains poorly
understood. We present a case of an asymptomatic 28-year-old male incidentally found to have IVC dilatation, reduced
inspiratory collapse, and normal right heart pressures.
