WebHow It Works. A shunt usually consists of two catheters and a one-way valve. The valve regulates the amount, flow direction, and pressure of cerebrospinal fluid out of the brain’s ventricles. As the pressure of cerebrospinal fluid inside the brain increases, the one-way valve opens and the excessive fluid drains to the downstream cavity. WebAtrial septal defects (ASD) are a group of malformations that allow shunting between the systemic and pulmonary circulation. Four types of ASDs have been described: primum, secundum, sinus venosus and coronary sinus defects. ASDs can present as isolated defects (the most common) or in association with other cardiac malformations, where they can ...
