Abstract

Recent technical improvements in cross-sectional echocardiography have made it possible to detect even mild organic regurgitation of the mitral and aortic valves in patients with acute rheumatic fever. To determine the prevalence and prognosis of subclinical valvitis, we have analyzed 104 patients with acute rheumatic fever referred to our institution. Of 53 patients who had no murmur, 22 of them with polyarthritis, 29 with chorea, and 2 with polyarthritis and chorea, 23 (43.4%) had subclinical valvitis. Isolated mitral regurgitation was the most common valvar lesion, seen in 82.6% of the patients. Isolated aortic regurgitation was detected in 4.4% of the cases, and combined mitral and aortic regurgitation in the remaining 13%. During follow-up, the degree of mitral regurgitation improved in 59.1%, decreased in 18.2%, and increased or remained unchanged in 22.7% according to the length of colour jet. According to criterions of velocity, mitral regurgitation improved in 86.4% of the patients, and increased or unchanged in the remaining 13.6%. Mitral regurgitation disappeared completely in 6 of the patients (27.3%) as judged according to both the length of colour jet and the velocity of regurgitation. Aortic regurgitation improved in all the patients with this problem, disappearing completely in two of the four.

Based on this experience, we suggest that not only the disappearance of regurgitation, but also improvements in the echocardiographic diagnostic criterions of regurgitation, such as the length of the colour jet less than 1 cm, or velocity less than 2.5 m/s, or indicative of regurgitation that is either intermittent or of short duration, should also be considered as criterions indicating improvement in valvar regurgitation in patients with subclinical rheumatic valvitis.
