Baroreceptor reflex in a patient with coarctation of the aorta.

We report the case of a 23-year-old man with coarctation of the aorta whose baroreceptor sensitivity was extremely reduced. Antihypertensive therapy was effectively performed after coarctectomy. Only one month after coarctectomy, baroreflex sensitivity had recovered. The present case is believed to be the first in which reduced baroreceptor sensitivity in coarctation of the aorta was reversible in the early phase after coarctectomy.
