Cirrhosis Cirrhosis Cirrhosis is a late stage of hepatic fibrosis that has resulted in widespread distortion of normal hepatic architecture. The most common cause is portal hypertension. The pathophysiology of IVCS is similar to superior vena cava syndrome (SVCS) because of the presence of an underlying process that inhibits venous return to the right atrium. Having DVT also increases the likelihood of a blood clot breaking off and traveling to the heart, lungs, or brain.

Doctors use echocardiograms to help them diagnose heart problems, such as damaged cardiac tissue, chamber enlargement, stiffening of the heart muscle, blood clots in the heart, fluid around the heart, and damaged or poorly functioning heart valves. The size of the IVC and its respiratory variability has been shown to correlate with right atrial pressure (RAP) and intravascular volume. Multiple regression analysis showed the impact of VO(2) max, cardiac index, and right ventricular and left ventricular end-diastolic dimensions on IVC diameter.
