BackgroundWe conducted a retrospective review of children undergoing surgery for coarctation of the aorta in our institution over the last ten years with the aim of evaluating overall patient survival as well as detecting factors affecting it. We tried to identify the risk factors for mortality.Methods And DataBetween January 1992 and December 2001, 201 patients with aortic coarctation were operated on at the Department of Cardiac Surgery of the Children's University Hospital, Bratislava. The three classes of aortic coarctation were represented: isolated coarctation, coarctation with ventricular septal defect (VSD) and coarctation with complex cardiac anomalies. Patients' preoperative, operative and immediate postoperative medical records were carefully studied with special attention paid to the type of lesion, patients' preoperative state, type of surgical technique employed, as well as the period of operation. For comparison, two equal time periods of follow-up were reviewed--1992 to 1996 and 1997 to 2001. The overall postoperative conditions of patients were also regularly monitored. Patient data were statistically analyzed using the JMP program version 4.04.ResultsAn overall survival of 90% was recorded over the period of follow-up, ranging between one and ten years. A further break down showed a statistically significant difference between the various types of aortic coarctation, p=0.0001. Patients with simple or isolated coarctation had a survival rate of 100%, those with ventricular septal defect (VSD) in addition to coarctation had a survival rate of 80% while patients with associated complex cardiac anomalies had a survival rate of 65%. An improvement on overall patient survival was recorded in the period between 1997 and 2001--96% as against 86% for the period between 1992 and 1996. On univariate statistical analysis, the following variables were identified as significant risk factors for death: 1) Complex cardiac anomalies (p<0.0001), 2) Age at operation less than one month (p<0.0001) and 3) Treatment prior to the year 1997 (p=0.02).ConclusionA considerable improvement on patient survival following surgery for coarctation of the aorta was recorded over the last five years. This could be attributed to new measures in preoperative, operative and postoperative care for patients with aortic coarctation. (Tab. 4, Fig. 5, Ref. 8.).
