Abstract

In its normal position about one third of the heart lies to the right and two thirds to the left of the midsternal line. In the developmental transposition of the heart and other viscera, or the heart alone, known as congenital dextrocardia, it occupies an isosymmetrical position, two thirds of its bulk being to the right and one third to the left of the midsternal line with the apex in the right nipple line. Acquired displacement of the heart to the right varies from the least discernible amount to the extreme condition in which the heart lies in contact with the lateral or posterolateral thoracic wall, but as a rule its long axis remains unchanged with the apex the farthest to the left. A displacement sufficient to bring about two thirds of the bulk of the heart to the right might by analogy to the congenital type be considered as
