Pulmonary arteriovenous fistula is an abnormal connection between an artery and vein in the lungs. As a result, blood passes through the lungs without receiving enough oxygen.
What is pulmonary aorta?
Pulmonary Artery. Function. Aorta is a large artery which carries oxygenated blood from the heart to other parts of the body. The primary function of the pulmonary artery is to carry deoxygenated blood from the heart to the lungs for purification.
What is aortic aneurysm?
An aortic aneurysm is a balloon-like bulge in the aorta, the large artery that carries blood from the heart through the chest and torso. Aortic aneurysms can dissect or rupture: The force of blood pumping can split the layers of the artery wall, allowing blood to leak in between them.
What is fistula in heart?
Coronary artery fistula is an abnormal connection between one of the coronary arteries and a heart chamber or another blood vessel. The coronary arteries are blood vessels that bring oxygen-rich blood to the heart.
Where is pulmonary aorta located?
Location. The pulmonary trunk, which is relatively short and wide, is located at the exit of the right ventricle. This main arterial branch is located above the heart to the left of the ascending aorta. These vessels pierce through the pericardium, which is the connective tissue lining around the heart.
What is difference between aorta and artery?

What are the risk factors for aortic aneurysm?
The risk factors for developing an aortic aneurysm include things that promote atherosclerosis of the vessel. These factors include uncontrolled hypertension, diabetes, smoking and high cholesterol. A sedentary and stressful lifestyle may contribute but likely much less than the other factors mentioned.
What is the prognosis for aortic aneurysm?
Survival rates. Without surgical repair of an aneurysm that is over 5cm in diameter, the annual survival rate is only about 20%. The risk of rupture of the abdominal aorta aneurysm increases with aneurysm size and aneurysms over 6 cm have a 25% yearly risk of rupture.
What is the main cause of aortic stenosis?
Aortic stenosis can be caused by congenital bicuspid aortic valve, scarred aortic valve of rheumatic fever, and wearing of aortic valve in the elderly. Aortic stenosis can cause chest pain, fainting, and heart failure leading to shortness of breath.
