The dramatic improvement in survival should lead to a larger number of GUCH patients than children with CHD in the new millennium. Although echocardiography remains the imaging modality of choice, cross-sectional imaging techniques have a decision-aiding function for the postoperative evaluation of surgical reconstructions as well as in the preparation of complex interventional procedures. Cardiovascular CT and MRI are often complementary in providing comprehensive complex anatomical evaluation, haemodynamic assessment of residual postoperative lesions and complications of surgery. A thorough understanding of postsurgical corrections is a prerequisite for choosing the optimal imaging techniques and achieving an accurate evaluation.

We investigated how the two vascular endothelial growth factor receptors VEGFR-1 and -2 regulate these events in chronically rejecting cardiac allografts. Methods and Results— Chronic rejection in mouse cardiac allografts induced primitive myocardial, adventitial, and intimal angiogenesis with endothelial expression of CD31, stem cell marker c-kit, and VEGFR-2. Experiments using marker gene mice or rats as cardiac allograft recipients revealed that replacement of cardiac allograft endothelial cells with recipient bone marrow– or non–bone marrow–derived cells was rare and restricted only to sites with severe injury. Targeting VEGFR-1 with neutralizing antibodies in mice reduced allograft CD11b + myelomonocyte infiltration and allograft arteriosclerosis. VEGFR-2 inhibition prevented myocardial c-kit + and CD31 + angiogenesis in the allograft, and decre...
