what is arteriovenous heart
Answers
Explanation:
An arteriovenous malformation (AVM) is an abnormal tangle of blood vessels connecting arteries and veins, which disrupts normal blood flow and oxygen circulation. Arteries are responsible for taking oxygen-rich blood from the heart to the brain. Veins carry the oxygen-depleted blood back to the lungs and heart.
Prognosis. The prognosis of an AVM depends on several factors, beginning with whether the AVM is discovered before or after bleeding. More than 90% of those who bleed survive the event.
The biggest concern related to AVMs is that they will cause uncontrolled bleeding, or hemorrhage. Fewer than 4 percent of AVMs hemorrhage, but those that do can have severe, even fatal, effects. Death as a direct result of an AVM happens in about 1 percent of people with AVMs.
