What is pulmonary artery Unifocalization?
In unifocalization, the misdirected blood vessels are rerouted into a single vessel (or into the pulmonary artery if it is present), which is then attached to the right ventricle of the heart through a conduit called a homograft. This restores normal circulation from lungs to heart.
What is Unifocalization of Aortopulmonary collaterals?
A surgery called unifocalization, performed soon after birth, can reroute the MAPCAs into the pulmonary artery in addition to repairing the Tetralogy of Fallot, restoring normal circulation from the lungs to the heart.
What is MAPCAs?
April 2012) Major aortopulmonary collateral arteries (or MAPCAs) are arteries that develop to supply blood to the lungs when native pulmonary circulation is underdeveloped. Instead of coming from the pulmonary trunk, supply develops from the aorta and other systemic arteries.
Can TOF lead to heart failure?
Conclusions. Cardiovascular disease is more common in TOF men 20 to 59 years old than in age-matched men from the general population, due to an increased prevalence of heart failure. Most heart failure seen in patients with TOF (of all ages) is mediated, at least in part, by pulmonic insufficiency.
What is Sano procedure?
The Sano shunt is a palliative surgical technique sometimes used as a step in Norwood procedure for hypoplastic left heart syndrome. The procedure involves placement of an extracardiac conduit between the right ventricle and main pulmonary artery stump.
What are major Aortopulmonary collateral arteries?
Major aortopulmonary collateral arteries (MAPCAs) are persistent tortuous fetal arteries that arise from the descending aorta and supply blood to pulmonary arteries in the lungs usually at the posterior aspect of hilum.
What is Glenn heart surgery?
The Glenn procedure is a type of open-heart surgery. The goals are to: Make blood from the upper part of the body (the head, neck, and arms) go directly to the lungs. This lets the blood pick up oxygen without passing through the heart. Take some of the extra work away from the right ventricle.
What is Takeuchi procedure?
The Takeuchi procedure involves creation of an aortopulmonary window and an intrapulmonary tunnel that baffles the aorta to the ostium of the anomalous left coronary artery. The incidence of late complications following the Takeuchi repair is unknown.
What is AP collateral?
Is TOF a heart disease?
What Is Tetralogy of Fallot (TOF)? Tetralogy of Fallot (fah-LO) is a congenital (present at birth) heart defect. In tetralogy of Fallot (TOF), four related heart defects change the way blood flows to the lungs and through the heart. TOF is repaired through open-heart surgery soon after birth or later in infancy.
How is unifocalisation used to treat pulmonary atresia?
A unifocalisation procedure is a corrective surgical technique used in patients with complete pulmonary artery atresia with major aortopulmonary collateral arteries (MAPCAs). In this technique, the collateral vessels supplying blood from the aorta directly to the lungs are brought into continuity in…
When to use the unifocalisation procedure in radiology?
Unifocalisation procedure. A unifocalisation procedure is a corrective surgical technique used in patients with complete pulmonary artery atresia with major aortopulmonary collateral arteries (MAPCAs). In this technique, the collateral vessels supplying blood from the aorta directly to the lungs are brought into continuity in…
How are collateral vessels brought into continuity during unifocalisation?
In this technique, the collateral vessels supplying blood from the aorta directly to the lungs are brought into continuity in a single vessel that supplies the pulmonary circulation usually via a conduit from the right ventricle or a shunt. 1.
