Background: This study aims to investigate the efficacy of computed tomography (CT) coronary angiography for the diagnosis of allograft vasculopathy.

Methods: Ten patients (9 males, 1 female; mean age 41±9.2 years; range 17 to 59 years) with a two-year follow-up after cardiac transplant who underwent control coronary angiography within the past three months were enrolled in this study. Computed tomography coronary angiography was performed on these patients. Standard angiographies of all patients were assessed by the same investigator. The BT coronary angiograms were assessed by another investigator who was blind to the previous assessment. Both assessment reports were compared by a third investigator.

Results: Eight patients had no major pathological findings with CT coronary angiography, whereas two patients had approximately 50% stenosis on the left anterior descending artery. Standard coronary angiography showed similar left anterior descending artery lesions at the same location in the same patients. The results of the standard coronary angiographies and the CT coronary angiographies were consistent for all patients.

Conclusion: Computed tomography angiography is less invasive and has lower risk for the patient. It has also some advantages including easy-to-use and cost-efficacy. Hospitalization is not required. Computed tomography coronary angiography may be an alternative to standard coronary angiography for the routine follow-up of allograft vasculopathy in cardiac transplant recipients.
