Vena cava, in air-breathing vertebrates, including humans, either of two major trunks, the anterior and posterior venae cavae, that deliver oxygen-depleted blood to the right side of the heart. The anterior vena cava, also known as the precava, drains th
A vena cava (plural: venae cavae) is a large vein that carries blood to the heart. You have two venae cavae: the superior vena cava and the inferior vena cava. Together, these large veins carry deoxygenated (with the oxygen removed) blood from all over the body to the right atrium of ...
The superior vena cava appeared extremely narrow and slit-like, with no adjacent mass or giant bulla. Pulmonary function testing indicated a forced expiratory volume in 1 second of 0.82L (44.4% of predicted value) and a forced expiratory volume in 1 second/forced vital capacity of 31.29%. A...
Persistence of a left superior vena cava is a congenital anomaly of considerable interest but by itself exerts no apparent adverse affect on cardiac function. It may occur as an isolated lesion but more often it is associated with many congenital cardiac anomalies. Heretofore it could only be dis...
Thrombosis of the inferior vena cava (IVC) is an underrecognized entity with a variety of clinical presentations. The general concepts of deep venous thrombosis (DVT) and thrombophlebitis are discussed in detail in Deep Venous Thrombosis. However, the implications and complexity of IVC thrombosis...

Introduction It has not been clarified how to identify the electrophysiological junction between right atrium (RA) and superior vena cava (SVC). The aim of this study was to identify the electrophysiological RA–SVC junction according to slow conduction or conduction bock and to examine the ...
According to one principle of the invention, a set of filter-wires is provided, which is to achieve the clot capturing function, capable of being deployed over a wide range of cone angles dependent upon the size of the vena cava. These filter-wires extend generally upstream from a central ...
