ABSTRACT
We investigated the effect of hydration on mitral valve prolapse (MVP). Ten subjects with documented diagnosis of MVP were studied before and after oral hydration with 1 L of fluid. Increased weight and cardiac output were present after hydration. Results showed that all 10 subjects with diagnosis of MVP before hydration continued to have MVP after hydration; however, subtle changes were detected, especially on auscultation. Seven of 9 subjects (with cardiac examination recorded before and after hydration) had auscultatory findings of MVP before hydration. No detectable auscultatory change after hydration was present in one subject; in six subjects a loss of either a click or a murmur was detected after hydration. All subjects had echocardiographically detected MVP before hydration; evidence of MVP on two-dimensional or M-mode examination persisted after hydration in all 10 subjects. Minor changes in the echocardiographic examination (M-mode n = 2, Doppler n = 1) were detected in three subjects. Thus we found that hydration of subjects with MVP did not alter the overall diagnosis; however, changes occurred, especially on auscultation. This suggests that alterations in hydration may affect auscultatory expression of MVP and could explain, in part, the variable auscultatory findings in patients with MVP.
