To define normal profiles of cardiac structure, function, and hemodynamics postcardiac transplantation using Doppler echocardiography. ⋯ Cardiac transplantation recipients commonly display the following: (1) trivial or mild degrees of mitral regurgitation; (2) as much as moderate tricuspid regurgitation; (3) septal hypokinesis; and (4) small pericardial effusions. There is an association between the presence of right ventricular enlargement and moderate tricuspid regurgitation.

A 48-year-old male patient had arrest due to rupture of a dissecting aneurysm of the thoracic aorta into the pericardial cavity with tamponade; he received treatment in a general hospital lacking the facilities to practice heart surgery. The patient was treated by means of intermittent pericardial drainage while being transferred to another hospital at 100-km distance for surgical treatment.
