Pulmonary arteriovenous malformation

Pulmonary arteriovenous malformation (PAVM) describes an anatomic communication between a pulmonary artery and a pulmonary vein leading to a right to left extracardiac shunt that can be asymptomatic or can lead to varying manifestations such as dyspnea, hemoptysis, and neurological symptoms.

Right-to-left shunt

Pattern of blood flow in the heart that deviates from the normal circuit of the circulatory system from the right side of the heart to the left.
