Heart-Reinforcing Corset

Congestive heart failure happens when the heart cannot pump enough blood to meet the body's metabolic needs. The condition is poorly understood, but generally thought to be caused by problems with the heart's valves or damage to its walls. In the short term, the heart tries to compensate by expanding so that it can pump more blood. But this starts a vicious cycle of decline that damages the overstretched heart even more.
