Presentation of severe brucellosis in 5-year-old boy - challenges and results.

Brucellosis is highly contagious zoonotic bacterial disease caused by gram-negative genus. It has a wide spectrum of clinical manifestations and due to variety and nonspecificity of clinical signs the diagnostics can be very complicated. We present a clinical case of severe chronic brucellosis in a 5-years old boy with long-term course of disease and multiorgan involvement.

A discrepancy between CT angiography and transesophageal echocardiographic measurements of the annular size affect long-term survival following trans-catheter aortic valve replacement.

Accurate measurement of the aortic valve annulus is critical for proper valve sizing for the transcatheter aortic valve replacement (TAVR) procedure. While computed tomography angiography (CTA) is the widely-accepted standard, two-dimensional (2D) and three-dimensional(3D) transesophageal echocardiography (TEE) is commonly performed to measure the size of the aortic valve and to verify appropriate seating of prostheses. Patients undergoing TAVR between 2013-2015 were examined.

Safety and efficiency of transplantation of allogenic multipotent stromal cells in surgical treatment of dilatated cardiomyopathy.

Clinical study of intracoronary transplantation of allogenic multipotent bone marrow stromal cells was carried out in patients with severe chronic cardiac failure against the background of dilatated cardiomyopathy. The results indicate that intracoronary injection of allogenic multipotent stromal precursors is a safe procedure. No complications and side effects directly or indirectly related to cell transplantation were recorded during the immediate and delayed postoperative periods.

Transplantation of allogenic cells in the therapy of patients with dilated cardiomyopathy.

We carried out a pilot study on intracoronary transplantation of prenatal allogenic skeletal myoblasts and multipotent bone marrow stromal cells to patients with dilated cardiomyopathy. Intracoronary transplantation of allogenic cells is a feasible and safe procedure: there were no life-threatening rhythm and conduction disturbances, symptoms of hemodynamic instability, and thromboembolic complications. Positive clinical effect of cell transplantation persisted for 6 months and consisted in decreased content of brain natriuretic peptide and improved tolerance to physical exercises.
