26 kwi 2021 · The left main coronary artery (LMCA) or left coronary artery (LCA) is one of the two main coronary arteries that supply the heart with oxygenated blood. Gross anatomy. Origin. The left main coronary artery is a branch of the ascending aorta, with its normal origin in the left aortic sinus, just superior to the aortic valve 1,2. Course.
The left main coronary artery (LMCA) originates from the left anterior aspect of the aortic bulb. The LMCA is short and branches into the two arteries supplying the anterior and left side of the heart, as follows: The left anterior descending coronary artery (LAD). The left circumflex coronary artery (LCX).
14 paź 2008 · The LCA divides almost immediately into the circumflex artery (Cx) and left anterior descending artery (LAD). On the left an axial CT-image. The LCA travels between the right ventricle outflow tract anteriorly and the left atrium posteriorly and divides into LAD and Cx.
The left coronary artery (LCA, also known as the left main coronary artery, or left main stem coronary artery) is a coronary artery that arises from the aorta above the left cusp of the aortic valve, and supplies blood to the left side of the heart muscle.
13 lip 2023 · The left cardiac surface is oblique and faces posterosuperiorly to the left hand side. The cardiac margins include: The obtuse (left) margin; The acute (inferior) margin; The right heart margin; The superior heart margin; There are impressions on the surface of the heart that serve as landmarks for the septa that separate the chambers internally.
Location: The left coronary artery (left main coronary artery) emerges from the aorta through the ostia of the left aortic cusp, within the sinus of Valsalva. The plane of the semilunar valve is tilted so that the ostium of the left coronary artery is superior and posterior to the right coronary ostium.
