05-02-04 This anterior anatomic view demonstrates juxtaposition of the atrial appendages with the left atrial appendage extending from the left atrium, posterior to the arterial pedicle, to lie adjacent to the right atrial appendage and to the right side of the great arteries. This is commonly associated with hypoplasia or atresia of the mitral valve, hypoplasia of the left ventricle and aortic valvar stenosis or atresia. Note the severe hypoplasia of the ascending aorta in this heart with a hypoplastic left ventricle (not shown).
