The term mitral valve prolapse (MVP) is used for a particular subset of patients
with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets
of the mitral valve extend above the plane of the atrioventricular junction during
ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was
studied by extraction of enzyme from the erythrocytes from 62 normal subjects and
78 MVP patients. Adenylate cyclase activity in the MVP group was increased
compared to that in controls [6.51 ±O.38 (mean±S.D., n= 78) vs. 2.76 ±O.12, n=
