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. Pulmonic stenosis - Wikipedia

   en.wikipedia.org/wiki/Pulmonic_stenosis

   If right ventricular failure develops, right atrial pressure will increase, and this may result in a persistent opening of the foramen ovale, shunting of unoxygenated blood from the right atrium into the left atrium, and systemic cyanosis. If pulmonary stenosis is severe, congestive heart failure occurs, and systemic venous engorgement will be ...

6. Hypoxia (medicine) - Wikipedia

   en.wikipedia.org/wiki/Hypoxia_(medicine)

   Pulmonary shunt, in which blood passes from the right to the left side of the heart without being oxygenated. This may be due to anatomical shunts, in which the blood bypasses the alveoli, via intracardiac shunts , pulmonary arteriovenous malformations , fistulas , and hepatopulmonary syndrome , or physiological shunting, in which blood passes ...

7. 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]
