X-ray showing aortic (top),mitral (bottom left) & tricuspid (bottom right) prosthetic valves in situ. The aortic (semi-lunar) valve lies between the aorta (the main artery of the body) & the left ventricle of the heart & prevents blood from flowing back into the ventricle. The mitral valve divides the left atrium & ventricle,consisting of 2 flaps (bicuspid) which allow blood to flow from atrium to ventricle but prevents any backflow. The tricuspid valve divides the right atrium & ventricle,consisting of 3 cusps which allow 1-way flow from the atrium (upper chamber) to the lower ventricle | |
