Hemodynamic aspects of the pulmonary collateral circulation

Noninvasive hemodynamic study of the pulmonary circulation.

UNLABELLED Cardiac catheterization is the reference method for the hemodynamic study of the pulmonary circulation. However, cardiac catheterization is an expensive and invasive method. Echocardiography is a reliable noninvasive alternative method. The purpose of our study was to determine the correlation between echocardiographic and haemodynamic data obtained by cardiac catheterization in pati...

Historical Aspects and Relevance of the Human Coronary Collateral Circulation

In 1669, anastomoses between the right and left coronary artery were first documented by Richard Lower of Amsterdam. Using post-mortem imaging, a debate followed on the existence of structural inter-coronary anastomoses, which was not resolved before the first half of the 20 ieth century in case of the presence of coronary artery disease (CAD), and not before the early 1960 ies in case of the n...

The clinical significance of the pulmonary collateral circulation.

THE NORMAL LUNG contains two distinct circulations of strikingly different origins, proportions, and functions. On the one hand is the huge pulmonary circulation, which originates in the right heart and pours the entire venous cardiac output into the lungs for gas exchange; on the other, is the diminutive systemic circulation, which delivers oxygenated blood to the lungs for the sustenance of i...
