    localized ballooning of a coronary artery

    A Coronary Artery Aneurysm (CAA) is a localized dilation or ballooning of a section of a coronary artery, which supplies blood to the heart muscle. This condition can lead to complications such as blood clots, heart attack, or rupture of the artery. It is often detected through imaging techniques like angiography and may require medical or surgical intervention depending on its size and associated risks.
