What is the typical 2-D echocardiographic appearance post-transplant?

In the context of post-transplant echocardiography, the typical 2-D appearance is characterized by the presence of double atria. This is often due to the surgical techniques used during heart transplantation, where the recipient's atria are usually preserved and the donor's heart is anastomosed to the remaining structures, leading to two separate atrial chambers being present.

This anatomical configuration can result from a combination of the donor heart's anatomical structures and the recipient's heart, creating the appearance of double atria on echocardiography. Recognizing this feature is essential for understanding the changes that occur after transplantation and for assessing the function and anatomy of the transplanted heart during echocardiographic evaluation.

Normal ventricular dimensions, single atrium, and thickened myocardial walls might be observed under different circumstances or pathologies, but they do not typically characterize the echocardiographic findings immediately following heart transplantation. Thus, the identification of double atria is a key feature that distinguishes post-transplant echocardiographic appearances from other cardiac conditions.
