Hemodynamic and clinical appraisal of coarctation four to seven years after resection and end-to-end anastomosis of the aorta

This study was undertaken to ascertain whether coarctation of the aorta produces permanent hemodynamic abnormalities that may persist despite resection and end-to-end anastomosis. The results of studies in 10 patients 4 to 7 years after operation are compared to those obtained before and immediately after operation. The most significant finding was continued decrease in residual coarctation, in addition to dramatic immediate postoperative improvement in the degree of circulatory impairment.
