To evaluate cardiac involvement in primary antiphospholipid syndrome, two-dimensional and Doppler echocardiographic studies were performed in 34 consecutive patients with this syndrome. All patients had an increased level of serum anticardiolipin antibodies with no evidence of malignancy or systemic lupus erythematosus. The clinical manifestations of primary antiphospholipid syndrome were arterial thrombosis in 14 patients, venous thrombosis in 6 and recurrent fetal loss in 14. Valvular lesions were observed on two-dimensional echocardiography in 11 patients (32%) (9 women and 2 men), aged 24 to 57 years (mean +/- 1 SD 36 +/- 10). Abnormal echocardiographic findings were observed in 9 (64%) of 14 patients with arterial thrombosis versus 1 (17%) of 6 patients with venous thrombosis and 1 (7%) of 14 patients with recurrent fetal loss. The most common echocardiographic abnormality was mitral leaflet thickening, found in five patients; this was associated with mitral regurgitation in three and with combined mild mitral stenosis and regurgitation in one patient. Localized subvalvular mitral thickening was observed in one patient and calcification of the anulus in another. Aortic valve thickening was observed in two patients, one of whom also had a moderate degree of aortic regurgitation. Vegetation-like lesions on the mitral or aortic valve were found in two patients. It is concluded that valvular lesions are commonly found in primary antiphospholipid syndrome, particularly when the syndrome is manifested by peripheral arterial thrombosis. The location and appearance of valvular lesions in this syndrome are heterogeneous. Most patients have no clinically significant valvular disease. Two-dimensional and Doppler echocardiographic studies are often informative in these patients.

Over the last 10 years, our knowledge of immunologically mediated processes involving the myocardium appears to have made quantum leaps. New and important disease entities such as AIDS have appeared and the cardiologist now becomes an important member of the "AIDS team." Our understanding of "older diseases" such as sarcoidosis, Lyme disease, systemic lupus and other connective tissue syndromes has significantly increased. The concept of high-dose steroid therapy for these processes may, in fact, turn out to be futile and more selective, as less dangerous immunosuppression is being introduced. This concept has significantly advanced in the field of cardiac transplantation where immunosuppression has now been usurped by specific immunotherapy aimed at selective aspects of the immune sequence. New and exciting concepts will emerge from the molecular biology laboratory that will have direct bearing on the management of patients with cardiovascular disorders. This information explosion will force the cardiovascular physician to become more in tune with the world of immunology and molecular biology. Many obvious, significant problems remain, such as accelerated atherosclerosis in the transplant patient and the role of myocarditis in the patient with heart failure. However, it will truly be an exciting decade in which to work and watch the unraveling of these mysteries and hopefully, the study of today's problems will give way to solutions and a clearer understanding of the heart as a target of immune injury.

Leiomyosarcomas are extremely rare primary cardiac tumours. A 46-year-old woman presenting with symptoms and signs of rapidly progressive left ventricular failure and apparent systemic lupus erythematosus was subsequently found to have a grade III/III left atrial leiomyosarcoma which was confirmed surgically. Pathology showed a cellular neoplasm arranged in fascicles with multinucleated giant cells, with areas of high grade sarcomatous change. The patient died seven months postoperatively with intractable heart failure. At autopsy, tumour infiltrated the pericardium, both atria and the right ventricle, with invasion of the diaphragm and posterior mediastinum. The current world literature is reviewed with respect to this rare and often misdiagnosed tumour.

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.

We report the case of a 21 year-old woman who developed systemic lupus erythematosus and fatal cardiac tamponade. Necropsy examination revealed cardiac tamponade as well as other findings of SLE and an unsuspected vasculitis similar to polyarteritis nodosa.

A young patient with systemic lupus erythematosus was admitted to our hospital because of acute myocardial infarction, and treated by thrombolysis. Coronary angiography revealed a significant stenosis of the left anterior descending artery, together with an intraluminal thrombus. Clotting studies demonstrated an anticoagulant factor suggestive of lupus erythematosus. We conclude that thrombolytic therapy can be useful in patients with systemic lupus erythematosus who present with acute myocardial infarction, although some caution is needed in treatment.

Myocardial infarction has rarely been reported in patients with systemic lupus erythematosus but may develop late in the disease usually as a result of severe and accelerated atherosclerosis or coronary arteritis. A 32-year-old man with untreated and unrecognized systemic lupus erythematosus, in the absence of conventional coronary risk factors (except family predisposition) and definite extracardiac manifestations of systemic lupus erythematosus had a silent myocardial infarction early in the course of the disease. A coronary arteriogram revealed multiple stenosis of the left anterior descending artery and critical stenosis of the right coronary artery. It is our belief that lupus vasculitis is a likely contributing factor in the development of obstructive coronary disease in this patient.

Cardiac involvement in patients with systemic lupus erythematosus (SLE) was assessed by full echocardiography and continuous wave Doppler in 50 consecutive patients and 50 age- and sex-matched control subjects in a prospective, blinded study. The left ventricular ejection fraction was decreased in patients compared to control subjects (61 +/- 9 vs 68 +/- 7%, p less than 0.001), whereas interventricular septum (12 +/- 3 vs 9 +/- 1 mm, p less than 0.001), and posterior wall dimension (9 +/- 2 vs 8 +/- 1 mm, p less than 0.001), left ventricular mass (186 +/- 54 vs 130 +/- 32 g, p less than 0.001) and mitral valve Doppler A:E ratio (0.8 +/- 0.2 vs 0.7 +/- 0.1, p less than 0.01) were increased. Pericardial effusion was detected in 27 patients and 5 control subjects, and valvular regurgitation was more frequent in the patients (aortic 2 vs 0; mitral 23 vs 5, p less than 0.001; tricuspid 34 vs 22, p less than 0.01 and pulmonary 28 vs 17, p less than 0.05). Mitral or aortic regurgitation was more common in patients with active SLE (60 vs 40%, difference not significant) but was not related to the duration of SLE (r = 0.02), duration of prednisone therapy (r = -0.13) or current dosage of prednisone (r = 0.01). This study demonstrates that pericardial effusion, valvular regurgitation and myocardial abnormalities are frequently present in patients with SLE.

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.
