Anticardiolipin antibodies (acLa) are associated with a thrombotic tendency (often involving cerebral ischemic events), are frequently present with systemic lupus erythematosus and have been found together with cardiac valve abnormalities. Previous studies evaluated patients characterized by the presence of acLa or lupus, precluding assessment of the frequency of acLa in those with valvular disease. This study aims to establish the prevalence of acLa in patients with valve disease in the absence of lupus and, furthermore, to determine the influence of acLa on the risk of cerebral events in valve disease. Eighty-seven consecutive patients with mitral or aortic regurgitation, or both, prospectively underwent enzyme-linked immunosorbent assay testing for immunoglobulin G (IgG) and M acLa, as did 24 normal subjects. AcLa values greater than or equal to 3 SD above the normal mean were considered "positive." Prior cerebral events were defined retrospectively. Of 87 patients with valvular disease, 26 had positive IgG acLa levels compared with 0 of 24 normal subjects (p less than 0.01). AcLa values did not vary with valve disease etiology. Focal cerebral events had occurred in 8 patients and were embolic or probably embolic in 7, including 7 of 26 IgG acLa-positive and 1 of 60 IgG acLa-negative patients (p less than 0.001). In the absence of lupus, IgG acLa is highly prevalent among patients with aortic or mitral regurgitation, or both; this association may indicate a relatively high risk for cerebral emboli.

A 36 year-old male patient developed acute pulmonary edema due acute mitral insufficiency as early manifestation of systemic lupus erythematosus. The patient was treated with supportive measures, oxygen, furosemide, and isosorbide dinitrate. He was started on prednisone 60 mg daily 14 days later, after the diagnosis of lupus was established. The patients is asymptomatic with mitral systolic murmur 5 months after hospital discharge.

A 25-year-old woman with active systemic lupus erythematosus and infective endocarditis was seen initially with porcine aortic bioprosthetic stenosis, perivalvar regurgitation, and native mitral regurgitation 9 years after aortic valve replacement for lupus endocarditis. Double-valve replacement was performed with St. Jude Medical mechanical prostheses. After operation the patient developed fever and an elevated white blood cell count. One month later she had increasing mitral and aortic perivalvular regurgitation and intermittent complete heart block. At reoperation both annuli showed evidence of continued infection, and she underwent annular reconstructions with pericardium and double-valve re-replacement. Cultures grew Mycoplasma hominis. Despite long-term therapy with appropriate antibiotics, within 2 months she developed recurrent perivalvar regurgitation with congestive heart failure. Orthotopic heart transplantation was performed. The postoperative course was notable for significant leukocytosis and spontaneous culture negative hemothorax that required thoracotomy for drainage. The patient recovered and is now well 14 months after operation.

A prospective M-mode, cross-sectional and Doppler echocardiographic study was performed on 75 patients with systemic lupus erythematosus and 60 sex- and age-matched control subjects. Compared with the control group, patients with lupus had an increased prevalence of echocardiographic abnormalities. These included pericardial effusion and/or thickening (37%), left ventricular hypertrophy (12%), global left ventricular hypokinesis (5%), segmental abnormalities of left ventricular wall motion (4%), right ventricular enlargement (4%), focal verrucous valvar thickening (12%), gross valvar thickening and dysfunction (8%), mitral regurgitation (25%) and aortic regurgitation (8%). Two patients with gross mitral valvar thickening and dysfunction subsequently underwent valvar replacement. Correlation between echocardiographic abnormalities and clinical parameters showed that pericardial effusion was significantly associated with pericardial pain (P less than 0.05) and active disease (P less than 0.001), and left ventricular hypertrophy with systemic hypertension (P less than 0.05). Thus, there was a high prevalence of cardiac abnormalities, especially pericardial and valvar lesions, in patients with systemic lupus erythematosus. Echocardiography is invaluable in identifying these abnormalities and should be used routinely for cardiac evaluation of these patients.

Two young women (aged 32 and 25 years) with systemic lupus erythematosus and heart valve lesions in association with antiphospholipid antibodies are presented. In addition to the presence of the 'lupus anticoagulant' and false positive Venereal Disease Research Laboratory (VDRL) tests, both patients had high levels of IgG anticardiolipin antibodies. The first patient additionally had contraceptive induced chorea, chorea gravidarum, seven miscarriages, livedo reticularis, pulmonary embolism, and thrombocytopenia and developed culture negative endocarditis as well as hypertension. The second patient, who had presented with hypertension, developed aortic and mitral regurgitation, suspected myocarditis, manifested transient ischaemic attacks, and responded well to anticoagulation and steroid treatment.

This paper describes a 47-years old patient with the history of lupus valvulitis for six and a half years, who had implantation of a Starr-Edwards prosthesis for a mitral insufficiency four years ago. This case represents the longest survival reported so far after mitral valve replacement for lupus valvulitis.

In this study, 100 consecutive, surgically excised, mitral valves were examined pathologically. The valves were classified according to primary conditions that resulted in valvular malfunction. Rheumatic mitral valvular diseases (stenosis and/or insufficiency) accounted for 54% of the cases. Myxomatous changes (prolapse) were present in 32 cases. Fifty-nine percent (19 cases) of those cases with myxomatous changes also had chordal rupture. Four of the cases had papillary muscle rupture, and in seven cases, papillary muscle dysfunction occurred. In one case bacterial endocarditis was observed on a previously normal valve. In one case the pathology of valvular. In one case the pathology of valvular changes was indeterminant. Lupus erythematosus was diagnosed in one patient, and mitral valve insufficiency may have resulted as a complication.

SLE affects most aspects of cardiac function, and recent studies have reported increasing cardiovascular morbidity and mortality. Pathologically, SLE is characterized by a pancarditis involving pericardium, myocardium, endocardium, and coronary arteries. In autopsy series, pericarditis has been found in 43% to 100% (mean 62%, Table I), and myocarditis was found in 8% to 78% (mean 40%, Table II), but both have been underdiagnosed clinically. Libman-Sacks lesions have been noted in 25% to 100% (mean 43%) and infective endocarditis in 1.1% to 4.9% of clinical and autopsy studies (Table III). Coronary disease may be due to arteritis, which should be treated with high-dose steroids, or it may be due to atherosclerosis, which is amenable to medical or surgical therapy. Valvular disease has been treated surgically, but with a combined surgical mortality as high as 25%. Aortic insufficiency and mitral regurgitation are the most common valvular problems, although aortic and mitral stenosis have also been reported. Hypertension has been noted in 14% to 69%, and heart failure in 5% to 44%. Evidence for a lupus cardiomyopathy, which may be subclinical, is reviewed. While steroids may ameliorate SLE pancarditis, they have also been associated with hypertension, LV hypertrophy, purulent and constrictive pericarditis, mitral regurgitation, and perhaps accelerated atherosclerosis. It remains to be seen if improved diagnosis and treatment of the cardiovascular manifestations of SLE can enhance survival.

A fatal case of systemic lupus erythaematosus complicated by myocardial infarction, papillary muscle dysfunction and mitral incompetence seven months before death is reported. Necropsy examination of the heart revealed that the infarct was due to multiple occlusive thrombi in epicardial branches of the corresponding coronary artery. No evidence of atherosclerosis or previous coronary arteritis was present.

Mitral annulus calcification (MAC), while a relatively frequent autopsy finding in older patients, is rare in childhood. Such calcification has generally been regarded as a degenerative change and of no clinical significance. Recent studies have shown that MAC may be associated with hemodynamically significant lesions including mitral insufficiency, arrhythmias, heart block, and, rarely, mitral stenosis. We have studied a case of massive calcification in the mitral annulus in a 17-year-old girl with juvenile rheumatoid arthritis and systemic lupus erythematosis. In this case, the MAC was considered secondary to the rheumatoid disease. MAC in younger patients with no history of rheumatic fever or bacterial endocarditis suggests an associated connective tissue disorder.
