Blood flows through the left atrium into the left ventricle. The left ventricle pumps the oxygen-rich blood to all parts of the body. Do right and left seem backward? That's because you're looking ...

The heart consists of four chambers. The top two chambers — the left and right atria — receive blood. The bottom two chambers — the left and right ventricles — pump blood from the heart.

An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop. This results in a communication between the left and right atrium ...

Mapping of both the morphologic right and left atria (the left atrium was accessed via the PFO) localized the earliest atrial activation site not to the morphologic right atrium, but rather to a ...

When right atrial enlargement occurs, it does not take longer for cardiac action potentials to travel through the atrial myocardium (similar to left atrial enlargement). However, the amplitude of ...

The septum separates the right-hand and left-hand side of the heart. The tricuspid valve separates the right atrium and right ventricle. It opens due to a build-up of pressure in the right atrium ...

AI can be used to identify different cardiac segments in CT scans, such as left and right atria, left and right ventricle and cardiac arteries. AI also integrates patient biometric data ...

Heterotaxy arises from a failure of the embryo to establish normal left-right asymmetry and is known to affect 3% of infants with congenital heart disease. A recessive mutation causing heterotaxy ...

The septum separates the right-hand and left-hand side of the heart. The tricuspid valve is located between the right atrium and right ventricle and opens due to a build-up of pressure in the ...
