What is the aortopulmonary window?
Aortopulmonary window is a rare heart defect in which there is a hole connecting the major artery taking blood from the heart to the body (the aorta) and the one taking blood from the heart to the lungs (pulmonary artery). The condition is congenital, which means it is present at birth.
What is difference between PDA and AP window?
Differentiation of an aortopulmonary window from a PDA can usually be confirmed with echocardiography; the left-to-right shunt is seen in the main pulmonary artery in the aortopulmonary window compared with the left pulmonary artery bifurcation in PDA. Cardiac catheterization confirms the diagnosis and hemodynamics.
What is aortopulmonary fistula?
An aortopulmonary artery fistula is an exceptionally rare and often highly lethal condition, usually diagnosed on post-mortem. In these cases, it has been attributed to iatrogenic complications of thoracic aortic surgery, ruptured aortic arch aneurysms and also chronic infectious processes of the aorta or lung [1].
Is aortopulmonary window normal?
Aortopulmonary window is rare — it accounts for less than 0.1 percent of all congenital heart defects. It is a type of congenital heart defect, meaning a baby is born with it. About 50 percent of children with this heart condition also have another type of heart defect.
What is the aortopulmonary shunt?
Aortopulmonary shunts are anatomic connections between the aorta (AO) and main or branch pulmonary arteries (PAs) causing left-to-right (L-R) shunts. Occasionally, in cases of severe PA hypertension (PAH), it causes right-to-left (R-L) shunt. Types of aortopulmonary shunts. Connection between AO and main PA (MPA):
What is Aortopulmonary window lymph node?
An aortopulmonary window is a heart defect in which there is a hole between the blood vessel that feeds the heart (the aorta) and the blood vessel going to the lungs (pulmonary artery). Because of this hole, blood from the aorta rushes into the pulmonary artery, and too much blood flows through the lungs.

What is aortopulmonary window lymph node?
What does the Blalock Thomas Taussig shunt do?
The Blalock-Taussig (BT) shunt mimics the role of the ductus arteriosus, meaning it allows blood to flow from a major artery through a connection to the pulmonary artery. Not only does this allow more blood to be oxygenated by the lungs, it also encourages the pulmonary arteries to grow, making the next surgery easier.
What are BT shunts made of?
The Modified BT Shunt (MBTS) is now performed and consists of a Gore-Tex (PTFE) graft (3.5-5.0 mm diameter) interposed between the innominate or subclavian artery and the ipsilateral pulmonary artery (PA). This can be performed on the left or right side, but is routinely on the right side at PMH.
What is Aortopulmonary collateral?
Major Aortopulmonary Collateral Artery (MAPCA) is an anomalous blood vessel that develops from aorta or its main branches and connects with pulmonary arteries [1]. It causes increase in pulmonary blood flow and serves as an additive or the only source of blood supply to lungs [2].
When was the first Blalock-Taussig shunt done?
History and etymology The procedure was first performed in a 15-month-old girl with tetralogy of Fallot in November 1944 at Johns Hopkins University Hospital in Baltimore, Maryland (USA). A modified Blalock-Taussig shunt technique using “plastic prostheses” was first described by Klinner in 1962 4.
Where is a BT shunt placed?
A BT shunt is tiny, measuring less than 5 millimeters (0.20 inches) in diameter. A surgeon attaches the two ends of the shunt to a major blood vessel, such as the subclavian artery, and to the pulmonary artery. The high-pressure arterial system will force blood through the BT shunt to the lungs to pick up more oxygen.
What is a aortopulmonary window?
Aortopulmonary Window (AP Window) Overview and Natural History. Aortopulmonary window (AP window) is a congenital heart defect characterized by a communication between the ascending aorta and the pulmonary artery in the presence of separate semilunar valves, an right ventricular outflow tract, and separate arterial trunks.
How does An aortopulmonary window affect a baby?
Babies with an aortopulmonary window have a hole in between the aorta and pulmonary artery. Because of this hole, blood from the aorta flows into the pulmonary artery, and as a result too much blood flows to the lungs. This causes high blood pressure in the lungs (a condition called pulmonary hypertension) and congestive heart failure.
What is the prevalence of aortopulmonary window?
Aortopulmonary window is very rare. It accounts for less than 1% of all congenital heart defects. This condition can occur on its own or with other heart defects such as: Tetralogy of Fallot. Pulmonary atresia. Truncus arteriosus. Atrial septal defect. Patent ductus arteriosus.
What is the AP window of the aorta?
Aortopulmonary Window AP window is most commonly a single communication between the intrapericardial portions of the aorta and the pulmonary artery and usually is located a few millimeters above the two separate semilunar valves.
