Left coronary artery
Left Coronary Artery
The Left Coronary Artery (LCA) (/lɛft kɔːrənɛri ɑːrtəri/), also known as the left main coronary artery (LMCA), is one of the two main coronary arteries that supply blood to the heart.
Etymology
The term "coronary" comes from the Latin corona, meaning "crown", due to the way these arteries encircle the heart in a crown-like fashion. The term "artery" is derived from the Ancient Greek ἀρτηρία (artēría), which means "pipe, conduit, or tube".
Anatomy
The LCA originates from the left aortic sinus, a part of the aorta, and branches into two major arteries: the circumflex artery (LCX) and the left anterior descending artery (LAD). These arteries further branch out to supply blood to the left side of the heart.
