Blood flows into the upper chambers (the right atrium and the left atrium). The lower chambers (the right and left ventricles) pump blood out of the heart. The heart valves open and close to keep blood flowing in the correct direction. </figcaption>

<figcaption class="asset-image-caption">TAPVD is a condition in which all four of the pulmonary veins are abnormally connected to the right atrium instead of the left atrium. This allows blood high in oxygen to enter the right side of the heart. Blood high in oxygen flows across an ASD, to the left ventricle, allowing some blood with oxygen to reach the body. Without the ASD, blood high in oxygen would not be able to reach the body.</figcaption>

<p>An atrial septal defect (ASD) usually accompanies this condition, allowing blood to flow from the right atrium to the left atrium. Without an ASD, the condition is fatal because there is no oxygenated blood returning from the heart to be circulated to the body. </p> | | <h2> Key points </h2>
<ul><li>Children with total anomalous pulmonary venous drainage are usually cyanotic, have trouble breathing, and have a heart murmur.</li>
<li>Surgery is required very shortly after birth, allowing for a very good outlook for children.</li></ul> | <p>An atrial septal defect (ASD) usually accompanies this condition, allowing blood to flow from the right atrium to the left atrium.
