Transposition complexes in the adult: a changing perspective.

This study has shown the heterogeneous group of patients with discordant ventricular arterial relations, their management and problems encountered during follow up. Patients after surgery for transposition are still relatively young by cardiology standards and their problems continue to evolve; nevertheless the future is becoming clearer. However there are still important lessons to be learnt by continued and diligent observation and systematic, multicenter research. It is important to maintain a low threshold for thorough re-evaluation of patients whenever new symptoms are discovered. Indeed, patients should undergo regular detailed investigations at timely intervals. It is vital that this evolving group of adult patients, as with most patients emerging from a childhood with other congenital heart malformations, is managed by cardiologists fully trained in congenital heart disease.
