Stem Cells and Resynchronization Cardiac
Summary
Same patients with dilated myocardiopathies with large areas of fibrosis has not been as successful after Cardiac Resynchronization Therapy, for Heart Failure patients in functional class III or IV. Therefore the investigators have decided to associate the Stem-Cell implant with Cardiac Resynchronization Therapy in these patients.
Description
About 120cc of blood are collected from the iliac bone marrow under epidural anesthesia.In the cell therapy lab this blood is harvested and mononuclear cells are separated.This procedure takes roughly 4 hours.After dilution the mononuclear cells are injected into the cardiac muscles with fibroses area through 20 shots.This procedure is indicated for patients with cardiac ischemia and left ventricular dysfunction(desynchrony), on whom all the others known therapies have failed.

Medical and Biotech [MESH] Definitions
Multipotent Stem Cells
Specialized stem cells that are committed to give rise to cells that have a particular function; examples are MYOBLASTS; MYELOID PROGENITOR CELLS; and skin stem cells.

Peripheral Blood Stem Cell Transplantation
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Embryonal Carcinoma Stem Cells
The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Lymphopoiesis
Formation of LYMPHOCYTES and PLASMA CELLS from the lymphoid stem cells which develop from the pluripotent HEMATOPOIETIC STEM CELLS in the BONE MARROW. These lymphoid stem cells differentiate into T-LYMPHOCYTES; B-LYMPHOCYTES; PLASMA CELLS; or NK-cells (KILLER CELLS, NATURAL) depending on the organ or tissues (LYMPHOID TISSUE) to which they migrate.
Stem Cell Research
Experimentation on STEM CELLS and on the use of stem cells.
