Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels. The cusps are pushed open to allow blood flow in one direction, and then closed to seal the...
aortic and pulmonary valvescoronary sinusright and left coronary arteriesventricleThe normal heart is the size of the patient's closed fist. The venae cave drain into the right atrium, which bears the fossa ovalis and receives the coronary sinus and the anterior cardiac vein. The atrium empties ...
aortic and pulmonary valvescoronary sinusright and left coronary arteriesventricleThe heart starts as a single tube. In the course of the first three months of intra-uterine life, it develops into the two atria and ventricles, connected to the appropriate veins and arteries. The partitions (septa...
The wall of the heart consists of three layers of tissue:Epicardium — protective layer mostly made of connective tissue.Myocardium — the muscles of the heart.Endocardium — lines the inside of the heart and protects the valves and chambers....

All of the structures of the heart (more than 250) on a labeled coronary CT in the 3 spatial planes: valves, cardiac cavities, coronary arteries, myocardium, etc. Our website was nominated for awards by the RSNA and JFR.
Valves are flap-like structures of the heart that allow blood to flow in one direction. Below are the four valves of the heart: Aortic valve: Prevents the backflow of blood as it is pumped from the left ventricle to the aorta. Mitral valve: Prevents the backflow of blood as it is pumpe...
The invasive imaging techniques have opened up new horizons to study, not only the anatomy of the heart, coronary arteries and great vessels, but also myocardial function, metabolism and perfusion, and the characterization of the valves, and pericardium. Different imaging modalities used different ter...
The heart valves are uniquely designed gates that promote the unidirectional flow of blood through the heart. They are attached to special muscular appendages that help to keep them stable. This article aims to explore the embryology and gross anatomy of the heart valves. Additional discussion ...
The heart functions by pumping blood both to the lungs and to the systems of the body. To prevent blood from flowing backwards or "regurgitating" back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricul...
