The superior Pulmonary veins (PVs) enter the left atrium (LA) from a superior, anterior, and lateral direction and the inferior PVs from the posterior direction. The right and left pulmonary arteries (PAs) lie just above and parallel to the right and left superior PVs. The ostium of the left inferior PV lies between the LA and descending aorta (Ao). There is neither artery nor bronchi (Br) adjacent to the right inferior PV. LSPV, left superior PV; LIPV. left inferior PV; RSPV, right superior PV; RIPV. right inferior PV.
