Abstract:
The flow pattern in the hepatic veins (HVs) is dependent on the cardiac cycle and right heart hemodynamics and influenced by the respiratory cycle and the liver parenchyma. Most disease states that affect the right heart alter the HV Doppler in a manner independent of the respiratory cycle. Some diseases that typically involve the pericardium, right ventricular myocardium, or respiratory system confer characteristic changes to the HV flow in a manner dependent on the respiratory cycle. Analysis of the HV Doppler with assessment of the respiratory changes in flow and their timing helps to distinguish among the various disease states. In this manuscript, we discuss the effect of respiration on HV flow in patients with abnormal right heart function and illustrate the use of the respiratory changes in the HV Doppler as a tool for diagnosis.

What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
