2. Pulmonary shunt - Wikipedia

   en.wikipedia.org/wiki/Pulmonary_shunt

   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.

3. Bidirectional Glenn procedure - Wikipedia

   en.wikipedia.org/wiki/Bidirectional_Glenn_procedure

   The mechanism of many of the risks and complications related to failure of the Glenn bidirectional shunt is thought to be thrombosis. Right-side dominant circulation, elevated pulmonary vascular resistance, and prolonged operative and recovery time are the major factors that increase the risk of complications and failure.

4. Norwood procedure - Wikipedia

   en.wikipedia.org/wiki/Norwood_procedure

   Heart Failure: The single ventricle must support both systemic and pulmonary circulation, which can lead to heart failure if demands exceed functional capacity. [ 30 ] Arrhythmias: Abnormal heart rhythms can occur due to the congenital defect or secondary to manipulation of cardiac tissue during surgery.

5. Cardiac shunt - Wikipedia

   en.wikipedia.org/wiki/Cardiac_shunt

   Atrial septal defect with left-to-right shunt. The left and right sides of the heart are named from a dorsal view, i.e., looking at the heart from the back or from the perspective of the person whose heart it is. There are four chambers in a heart: an atrium (upper) and a ventricle (lower) on both the left and right sides. [1]

6. Pulmonary-to-systemic shunt - Wikipedia

   en.wikipedia.org/wiki/Pulmonary-to-systemic_shunt

   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 ...

7. Aortopulmonary window - Wikipedia

   en.wikipedia.org/wiki/Aortopulmonary_window

   Aortopulmonary window (APW) is a faulty connection between the aorta and the main pulmonary artery that results in a significant left-to-right shunt. [2] The aortopulmonary window is the rarest of septal defects, accounting for 0.15-0.6% of all congenital heart malformations. [4]
