091: Cardiac sarcoidosis, myocardial spect contribution

Background Sarcoidosis is a multiorgan systemic disease rare. The cardiac involvement is common, but only 3-5% of them are symptomatic up to sudden death. The prognosis depends on early and potential reversibility of lesions treated. Myocardial SPECT (TSM) and especially magnetic resonance (NMR) are examinations of choice to objectify sarcoid lesions. Objective The aim of this study is to assess the prevalence of possible myocardial sarcodosique and monitored by an evolutionary TSM MIBI Methods For this, we have, in a prospective study after a clinical examination, electrical and echocardiographic sought, the TSM MIBI rest, fixing defects after myocardial reversible injection of a vasodilator dipyridamole, 31 consecutive patients addressed to the pulmonology department mediastinal-pulmonary sarcoidosis. Results There are 22 men and 09 whose average age was 38±11 years. Six patients (19%) had problems with perfusionnels extent of tracer uptake of 3.8±1.7 segments of 17. On the ECG, there is a supraventricular tachycardia, one case of atrioventricular block of first degree, two cases of ventricular extrasystolies bigeminees. The echocardiadiographies are normal except for a case of diastolic dysfunction. The standard therapeutic SST in 5 patients. The TSM MIBI such as NMR is a good diagnostic examination and scalable for a proper and early treatment. Available in our institution, it enabled us to diagnose 19% of cases of myocardial sarcoid lesions.
