Abstract
Transient elevations of the potent vasoconstrictive peptide endothelin have been reported to occur with the institution of cardiopulmonary bypass. We measured plasma endothelin levels in a 24-year-old gravid patient undergoing a mitral valve replacement operation. Plasma endothelin levels increased by more than 250% in the first 24 hours postoperatively and remained elevated above baseline values at 36 hours postoperatively.
