Regurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart. The valves in your heart may be damaged due to infection, rheumatic heart disease, wear and tear, tissue weakening or deterioration, or birth (congenital) defects.egurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart.

Some cardiovascular researchers believe that the heart contains cardiac stem cells or progenitor cells which can become mature cardiomyocytes (beating heart cells) following an injury and regenerate the damaged heart.he effect was quite significant and mice treated with these microRNAs had near-normal heart function 60 days after a heart attack. Based on these two Nature papers, it appears that the cardiomyocytes in the adult heart have a kind of brake that prevents them from proliferating.
