Double outlet right ventricle in a human embryo
Abstract
A human embryo of 14 mm crown-rump length is described to exemplify the anomaly of double outlet right ventricle with subaortic defect. The configuration of endocardial swellings in the outflow portion of the heart are compatible with the general architecture of full-grown examples of the anomaly. This configuration differs considerably from normal embryonic anatomy, but is still supported by the architecture of the myoepicardial mantle. It is concluded that endocardial swellings play a secondary role in the determination of fullgrown cardiac anatomy.
