OBJECTIVE
Mitral valve prolapse (MVP) is a heart valve anomaly that affects a considerable segment of the population. Studies of patients with isolated MVP have shown that aortic distensibility decreased as the aortic diameter increased. The aim of this study was to compare evaluations of aortic distensibility in MVP patients using both applanation tonometry and the conventional echocardiographic examination.


METHODS
A total of 36 consecutive patients with MVP (16 male and 20 female) and 23 healthy controls (11 male and 12 female) were included in this study. The difference in aortic diameter and distensibility was examined using echocardiography and pulse wave velocity (PWV) was measured with applanation tonometry.


RESULTS
According to the echocardiographic measurements, the aortic distensibility was lower in the MVP patients than in the control group (6.2±4.0 cm².dyn⁻¹.10⁻⁶ vs. 10.0±5.2 cm². dyn⁻¹.10⁻⁶; p=0.02). The PWV measured with applanation tonometry was significantly higher in the MVP patients than in the control group (9.0±2.4 m/s vs. 7.2±1.4 m/s; p=0.006).


CONCLUSION
The results of this study showed that aortic distensibility was reduced in patients with isolated MVP compared with a healthy control group. There was a moderate negative correlation between the results of both methods.
