Life-long follow-up in congenitally corrected transposition

A male patient with congenitally corrected transposition, with no associated cardiac malformations, was diagnosed in childhood and followed until his death at age 28. He underwent two cardiac gated single photon emission computed tomographies over a two year period, which demonstrated progression of ischaemia and reduction of systolic function. The findings suggest that, when the systemic ventricle is perfused by the morphologically right coronary artery, there may be inadequate perfusion to supply any subsequent extensive hypertrophy.
