—We found very interesting the article by Pines et al in the July 1986 issue of the Archives.1 These authors show a high incidence of MVP (56%) in a group of 25 patients with PA. The MVP was diagnosed by M-mode echocardiography. Our group is currently investigating the cardiovascular abnormalities associated with PA. Up to now, 44 patients, 30 men and 14 women, have entered the study (mean age, 45 years). Test results for HLA-B27 were positive in 33.8% of our patients. Electrocardiography, M-mode and 2D-echocardiography, and pulsed Doppler test were performed. Preliminary data have already been shown at the 16th National Congress of the Spanish Society of Rheumatology.2M-mode echocardiography is not sensitive enough to evaluate mitral leaflet motion in MVP; 2D-echocardiography circumvents some of these problems and permits visualization of both mitral leaflets and subvalvular apparatus.3 Thus, some authors have proposed this
