Value of certain echocardiographic findings in the initial suspicion of Behçet's disease.

ABSTRACT

PURPOSE: To describe the echocardiographic findings detected as first manifestations of Behçet's disease (BD) and compare these findings with those detected in established cases of BD receiving regular medical treatment. METHODS: Two groups of patients were studied. Group 1 comprised 41 patients with BD on regular medical treatment. Group 2 comprised 5 previously healthy patients who presented to the cardiology department because of cardiac symptoms and were diagnosed in retrospect during hospitalization as BD. Thirty-two age- and sex-matched individuals served as control subjects (control group). All patients and controls underwent complete M-mode, two-dimensional, and Doppler transthoracic echocardiographic examinations. RESULTS: Of the 41 treated patients with BD (mean age 32 ± 8 years, 90% males, mean duration since diagnosis 14.5 years), only 1 patient was found to have severe aortic regurgitation secondary to aortic root dilation. On the other hand, the 5 previously healthy patients who presented with cardiac symptoms (mean age 24 ± 6 years, all males) had significant cardiac involvement and evident echocardiographic findings (P < 0.001). Four cases had intracardiac masses 3 in the right atrium (RA), 1 in the right ventricle (RV), while the last patient had pericardial effusion (PE). All these patients were diagnosed in retrospect as BD. The RA masses disappeared on medical therapy, while the RV mass was surgically excised and proved to be multiple thrombi histopathologically. The patient with PE had recurrent attacks of massive effusion so a pericardial window was performed surgically. CONCLUSION: Diagnosis of BD might be initially suspected by the cardiologists based on certain echocardiographic findings, namely the presence of right-sided masses. Diagnosis of BD in such patients has important therapeutic implications and accordingly prognostic value.
