The aim of this study was to evaluate the results following surgeries for the treatment of coarctation of the aorta in Chinese paediatric patients and to compare the surgery outcomes between simple and complex coarctation procedures.
Between January 2006 and December 2011, 107 consecutive paediatric patients with coarctation of the aorta underwent surgery. Forty-four patients (41.12%) were classified as having simple coarctations (group A), and 54 patients (50.47%) were classified as having complex coarctations (group B). Echocardiography and the resting systolic blood pressure were evaluated prior to the operation, at one month following the operation, and then once annually.
Follow-up was 93.5% complete (100 patients), without significant differences between the two groups. Arch hypoplasias and bicuspid aortic valves were initially present in 10 (9.35%) and 11 (10.28%) of 107 patients, respectively. There were no deaths among the group A patients and three (5.56%) early deaths among the group B patients. There was a significant difference in the restenosis incidence rate between the two groups during the most recent follow-up consultations (p<0.05). Additionally, only 10 of 43 group A and 10 of 51 group B patients had persistently abnormal blood pressures during the annual follow-up consultations.
The postoperative restenosis ratio was increased in the complex coarctation group compared with the simple coarctation group. Additionally, the complex coarctation patients who did not have restenosis at follow-up had a lower proportion of hypertension.
