Abstract:
Doppler interrogation of blood flow in the hepatic veins (HVs) is a part of any comprehensive echocardiographic examination. Data derived from the HV Doppler provide a useful tool for the assessment of right heart function. Beyond its dependence on the cardiac cycle, right heart hemodynamics, and compliance of the liver parenchyma, blood flow in the HVs is influenced by the respiratory cycle. Systematic analysis of the behavior of the HV Doppler during respiration allows one to recognize normal and abnormal flow-patterns and distinguish among various disease states that involve the right heart. In this manuscript we discuss the effect of respiration on the HV Doppler in individuals with normal right heart function.

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...
