Unsupported valvuloplasty is effective and safe for treatment of degenerative mitral regurgitation, representing an adequate therapeutic alternative for selected cases.

This paper describes a case of an aggressive primary splenic angiosarcoma in a 29-year-old man and makes a review of its clinicai findings, pathologic reports, treatment and prognosis. Angiosarcomas comprise less than 1% of soft tissue sarcomas, and only a small percentage of these tumors arise in the spleen. These tumors usually represent a diagnostic challenge for the pathologist in view of its variegated histology, and the development of new immu-nohistochemical markers for vascular tumors like CD31 (platelet-endothelial cell adhesion molecule) helps to rule out other diagnoses. There is no standard chemotherapy treatment for angiosarcomas, and the prognosis of splenic angiosarcoma is particularly poor.

1 AbstractPurpose: To investigate the safety and clinical, hemodynamic and tissue improvement ability in mini pigs undergoing cell and gene therapy for the treatment of acute myocardial infarction. Methods: Thirty-two mini pigs Br1 lineage, 12 months old, undergoing induction of acute myocardial infarction by occlusion of the diagonal branch of the paraconal coronary. They were divided into 4 groups: one control group and 3 treatment groups (cell therapy and gene cell therapy). Echocardiography reviews were performed on three occasions and histopathological analysis was performed after 4 weeks. Analysis of variance (ANOVA), Tukey and Wilcoxon tests, were performed. Results: Association of vascular endothelial growth factor (VEGF) with angiopoietin1 (Ang1) presented satisfactory results in the improvement of ventricular function following ischemic cardiomyopathy in mini pigs when compared to the results of the other treated groups. Conclusion:The therapy with VEGF and the combination of VEGF with Ang1, promoted recovered function of the myocardium, characterized by reduced akinetic area and induction of neovascularization.
