The four valves in a human heart determine the pathway of blood flow through the heart. (martinpollins.com)
The valves prevent the backward flow of blood. (martinpollins.com)
When the valve(s) do not close completely, it causes blood to flow backwards through the valve and reduces forward blood flow, leading to volume overload in the heart. (martinpollins.com)
When the valve(s) opening becomes narrowed, it limits the flow of blood out of the ventricles or atria. (martinpollins.com)

The reversal of blood flow might be irreversible, and surgery could lead to severe complications or worsen the condition. (longmoreclinic.org)

If a baby shows symptoms of TGA after birth, the clinician may order an echocardiogram (echo) to see the heart's structure and how well it is pumping blood. (hopkinsmedicine.org)

The extent to which a PDA affects any given dog depends on the degree of patency, or size, of the ductus. (discoveryspace.ca)

The ductus arteriosus is a normal, small communicating blood vessel beside the heart, connecting the pulmonary artery (which carries blood to the lungs) and the aorta (which carries blood to the rest of the body). (discoveryspace.ca)
In a normal heart, oxygen-depleted ("blue") blood is pumped from the right side of the heart, through the pulmonary artery, to the lungs where it is oxygenated. (the-medical-dictionary.com)
In a normal heart, the pulmonary artery pumps blood to the lungs, where it gathers oxygen. (hopkinsmedicine.org)
The ductus arteriosus is a normal part of fetal circulation. (childrensnational.org)
Finally, turbulence can be heard when the blood is too thin (anemia) or even when a patient is very excited, causing the heart to pump faster and harder than normal. (vin.com)
The normal adult blood volume is 5 liters (a little over 1 gallon) and it usually passes through the heart once a minute. (medscape.com)

At birth, mammals must adapt from living in a fluid environment (the amniotic fluid in the mother's uterus) where they acquire oxygen through the mother's blood, to breathing air and acquiring oxygen through their own lungs. (discoveryspace.ca)

It is a type of transposition of the great vessels, and was first described in 1797 by Matthew Baillie. (the-medical-dictionary.com)
Most of the associated anomalies relate to transposition of the great vessels. (medscape.com)
Males present more frequently with transposed great vessels than females. (medscape.com)
This is a small duct that connects two of the great vessels of the heart while the Black Pomeranian puppy is still in the womb. (thegoodypet.com)

This is a unique procedure to enable the mixing of pure and impure blood which enhances survival of the patient. (sssihms.org)

Large vascular anastomoses in the vertebral canal formed the only blood supply to the head. (duke.edu)
To meet this necessity the blood vascular system is formed. (co.ma)

The two-vessel umbilical cord of the acardius contained calcified mural thrombi in both vessels. (duke.edu)

Because of the obligatory right-to-left shunt at the level of the atria, saturation of the left atrial blood is diminished. (medscape.com)

A doctor will close a PDA if the size of the opening is big enough that the lungs could become overloaded with blood, a condition that can lead to an enlarged heart. (kidshealth.org)
After birth, the ductus arteriosus is no longer needed and will naturally close. (nives24h.com)
