This excerpt has been provided in the absence of an abstract.

Although many studies of coarctation of the aortic isthmus have been reported, none have correlated the hemodynamic, angiographic, and pathologic findings. Of 84 patients (62 male, 22 female; age range, 1 to 49 years, average, 17 years), all had murmurs; 78 had absent, diminished, or delayed femoral pulsations; 51 had cuff systolic blood pressures in the arm above 140 mm Hg, and 30 had diastolic pressures above 90 mm Hg. Fifty-two patients had angiograms. Average pressure gradients (millimeters of mercury) obtained by direct measurements above and below the coarctations in 35 patients were peak systolic, 44; mean, 17; diastolic, 5.
