CT demonstrates the left anatomic connections in a heterotopic transplant. In the surgical approach used in this patient, only the left heart vessels are anastomosed ("left ventricular assist"). The alternative "bi-ventricular assist" approach would also anastomose donor and native main pulmonary arteries1.
Note the relatively small donor heart, native heart with calcified left ventricular aneurysm and calcified coronary arteries (reflecting underlying ischaemic aetiology), dense liver which is likely due to amiodarone in this patient.
