Cyanotic Heart Disease (CHD)
Cyanotic heart defect is a group-type of congenital heart defect (CHD) that occurs due to deoxygenated blood bypassing the lungs and entering the systemic circulation or a mixture of oxygenated and unoxygenated blood entering the systemic circulation. It is caused by structural defects of the heart, or any condition which increases pulmonary vascular resistance. The result being the development of collateral circulation. Mathematical models are used to address the issue of pressure level alterations of circulation after the procedures. The pulmonary pressure resistance in the cavopulmonary connection is increased, and these models permit clear analyses of the pressure increase allowing doctors to avoid possible venous circulation congestion.
