RESUMO
Primary cardiac tumors are a rare entity. The presence of a mass in the left atrium suggests myxoma as a first differential diagnosis. Here we present a rare case of a woman with exertional dyspnea with a large tumor in the left atrium. The patient was extensively studied with echocardiography, cardiac MRI, coronary angiography and computed tomography. Extracardiac neoplastic involvement was ruled out. The patient underwent surgery, the mass was removed, and the final diagnosis was an undifferentiated pleomorphic sarcoma.
RESUMO
UNLABELLED: NT-probrain natriuretic peptide (NT-proBNP) has been associated with left ventricular (LV) dysfunction and adverse outcome in patients with non-ST-elevation acute coronary syndromes (NSTEACS). However, the underlying pathophysiological mechanisms responsible for this association have not been well established. We sought to explore the relation between NT-proBNP levels and extension of coronary artery disease (CAD) and the presence of more complex and severe coronary lesions. METHODS: This prospective, multicenter angiographic substudy included 585 patients admitted with NSTEACS. Blinded measurements of NT-proBNP and troponin T were performed at a median time of 3 hours after admission and analyzed centrally. Angiograms were read at a core laboratory by 2 independent readers blinded to patient data. Complex coronary lesion was defined as the presence of at least one of the following: thrombus (+), TIMI flow < 2, or ulcerated plaque. RESULTS: NT-probrain natriuretic peptide levels increased proportionally as LV function decreased. The levels of NT-proBNP were directly related to the extent of the CAD. This association was maintained when we analyzed patients with normal LV function (n = 257). Patients with complex coronary lesions or those with at least one of its individual component had higher levels of NT-proBNP compared with those without complex coronary lesions. After adjusting for clinical and electrocardiographic variables and other biomarkers, positive troponin (OR 2.20, 95% CI 1.50-3.22, P < .0001) and supramedian NT-proBNP levels (OR 1.72, 95% CI 1.19-2.47, P = .003) independently contributed to the prediction of complex coronary lesions. CONCLUSION: In this study of patients with NSTEACS, NT-proBNP levels progressively increase with the severity of CAD and degree of LV dysfunction. Increased levels of NT-proBNP independently predict the presence of more complex coronary lesions.

BACKGROUND: Inflammatory markers have been associated with adverse clinical outcome in patients with acute coronary syndromes (ACS). In addition, angiographic plaque morphology and extension of coronary artery disease has been related to worse prognosis in this group of patients. The aim of the present study was to determine if the clinical prognostic value of C-reactive protein (CRP), an inflammatory marker, can by associated with the angiographic findings in patients with non-ST elevation ACS. METHODS: This prospective multicenter cohort study included 1253 patients with non-ST elevation ACS. CRP, which was considered positive (+) if >/=3 mg/l, was measured at a median of 9 h from symptoms onset and were kept blinded until the end of the study. Coronary angiography was performed in 633 patients (50%). The presence of complex coronary lesions (CCLs) was defined as the presence of any of the following: thrombus (+), Thrombolysis In Myocardial Infarction (TIMI) flow

La angioplastía transluminal percutánea (ATP) de los troncos supraórticos son en la actualidad un método seguro, eficaz y económico para el tratamiento de las lesiones estenóticas de los vasos con destino cervicoencefálico, además de que los indices de morbimortalidad son similares o menores a los publicados para endarterectomía. Este trabajo presenta una revisión bibliografíca de la técnica, indicaciones, resultados y complicaciones de la ATP. La puede llegar a ser método de elección par el tratamiento de las estenósis no ulceradas de los troncos supraórticos.
