Cor Biloculare (Two Chambered Heart)
Cor biloculare refers to a two-chambered heart. Cor biloculare is due to failure of development of the walls that normally separate the two atria (interatrial septum) and the two ventricles (interventricular septum). Curiously enough, a two chambered heart, while not nearly as efficient as a four chamgered heart, is compatible with life, although perhaps not long life. In fact, all reptiles have two chambered hearts. Treatment, when needed, is similar to the treatment of congestive heart failure as the extra strain on the heart can lead to this condition. I cannot find any evidence that it is being treated surgically, except perhaps by heart transplant. If you have other information, please contact me at firstname.lastname@example.org.
