ADVANCED Regional & Pain

During repair for coarctation of the aorta in a healthy 13-year-old patient, right radial artery pressure increases from 100/60 to 105/70 mmHg after the aorta is cross clamped. This most likely indicates that

(A) collateral blood flow has decreased the hemodynamic consequences of cross-clamping
(B) left ventricular hypertrophy has decreased left ventricular compliance
(C) spinal cord blood flow is impaired
(D) the coarctation has decreased aortic diameter less than 50%
(E) the coarctation involves the origin of the right subclavian artery
