In 9 of 12 patients who underwent cardiac transplantation computed tomography was performed. In 5 of them CT was obtained also before the surgical treatment. In all patients angio-CT technique was performed, while the ECG-gated technique was employed only before surgery. CT shows changes in morphology of both atria but over all of the right one, and rotation of the heart on the longitudinal axis. The conditions of the pericardium are particularly well demonstrated: in 5 cases pericardial effusion was observed, 3 times localized and 2 times diffuse. Only in 1 patient a small thrombus in the right atrium was demonstrated. CT allows the possibility to obtain simultaneously information on mediastinum, lungs and pleura. Pleural effusion, pulmonary infections and mediastinal complications are easily demonstrated.

Thirty patients with myocardial infarction were studied using Digital Subtraction Ventriculography with Intravenous injection (DSVIV) between 3 and 6 days from myocardial infarction and were checked after 30 and 90 days. The variation of ejection fraction in the controls was not important. The wall motion provided precise indications regarding the infarctual regions. Digital subtraction ventriculography seems to be a very interesting tool in the study of the left ventricle in the evolution of myocardial infarction, thanks to a low invasivity, providing data on ventricular function.
