Abstract

OBJECTIVE:

To determine the prevalence of cardiac valvular involvement in patients with the primary antiphospholipid syndrome.

DESIGN:

Cross-sectional study with evaluation of case patients and control patients by Doppler echocardiography. The mean follow-up for case patients was 22 months.

SETTING:

University-based tertiary medical center.

PATIENTS:

Twenty-eight consecutive patients who were diagnosed with the primary antiphospholipid syndrome during a 10-year period; 28 age- and sex-matched healthy controls.

MEASUREMENTS AND MAIN RESULTS:

Ten patients (36%; 95% Cl, 19% to 56%) with the primary antiphospholipid syndrome had cardiac valvular involvement: Four patients had mitral valve involvement; four patients, aortic valve involvement; and two patients, both mitral and aortic valvular involvement; no patients had tricuspid or pulmonary valve disease. Eight of 10 patients had a regurgitant murmur. None of the control patients had valvular disease. The mean mitral valve thickness in patients with mitral valve involvement was 7.0 +/- 1.6 mm, compared with 2.7 +/- 0.8 mm in patients with normal valves and 3.2 +/- 0.9 mm in the control group. The mean aortic valve thickness in patients with aortic valve involvement was 3.8 +/- 0.5 mm compared with 1.4 +/- 0.3 mm in patients with normal valves and 1.4 +/- 0.5 mm in the control group. Stenotic lesions were not found. Regurgitation was severe in two patients (one required surgery), moderate in three patients, and mild in three patients.

CONCLUSIONS:

Valvular involvement is frequently found in patients with the primary antiphospholipid syndrome. The lesions are left-sided, causing regurgitation that may be clinically important.
