A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region.
It is said that hemoptysis is caused by the formation of anomalous anastomosis (bronchial artery-pulmonary artery shunt) between the bronchial artery and the pulmonary artery, and if the bronchial artery is embolized, hemorrhage will cease. [1] This is a fundamental concept of BAE.
The Blalock–Thomas–Taussig shunt (BTT shunt), [1] previously known as the Blalock–Taussig Shunt (BT shunt), [2] is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease [3] such as pulmonary atresia and tetralogy of Fallot, which are common causes of blue baby syndrome. [3]
MBTS shunt provides connection from the pulmonary artery to brachiocephalic artery or subclavian artery, while the RVPA conduit provides connection from right ventricle to pulmonary artery. [21] [5] Blalock-Taussig Shunt, a Gore-Tex conduit (a kind of plastic tubing) is used to connect the subclavian artery to the pulmonary artery. In this case ...
The most common cause of right-to-left shunt is the Tetralogy of Fallot, a congenital cardiac anomaly characterized by four co-existing heart defects. Pulmonary stenosis (narrowing of the pulmonary valve and outflow tract, obstructing blood flow from the right ventricle to the pulmonary artery)
A pulmonary-to-systemic shunt is a cardiac shunt which allows, or is designed to cause, blood to flow from the pulmonary circulation to the systemic circulation. [1] [2] This occurs when: there is a passage between two or more of the great vessels; and, pulmonic pressure is higher than systemic pressure and/or the shunt has a one-way valvular ...
This might have been caused by blood clotting, heart failure, pulmonary emphysema, or damage in alveolar capillaries. [12] Diagram of pulmonary shunt in alveoli and pulmonary capillary. Secondly, the pulmonary shunt is caused by zero or low V/Q ratio due to insufficient ventilation and excess perfusion. Improper ventilation lowers blood ...
Pulmonary arteriovenous malformations are abnormal communications between the veins and arteries of the pulmonary circulation, leading to a right-to-left blood shunt. [5] [6] They have no symptoms in up to 29% of all cases, [7] however they can give rise to serious complications including hemorrhage, and infection. [5]
