Specific Cardiac Defects
Mission Hospital’s highly skilled team has the proven expertise to
care for patients with many types of cardiac defects:
Coronary Artery Disease
Coronary artery disease causes a decrease in blood flow to the heart muscle.
When fatty substances called plaque are deposited in the inner lining
of an artery, the artery is narrowed, restricting or blocking blood flow.
The rupture of this plaque can cause a heart attack and subsequent chest
pain. Mission Hospital offers the latest therapies and treatments for
coronary artery disease, from lifestyle management to the most advanced
open-heart surgery techniques.
The heart's valves open and close to keep blood flowing properly, with
oxygenated blood flowing into the heart and blood needing oxygen flowing
out. Valve disease occurs when the heart's valves do not function
properly. Some disorders cause stenosis (narrowing) or obstruction of
the valves, which forces the heart to work harder to pump blood to the
body. Other valve disorders are characterized by the inability of valves
to close completely. This regurgitation or insufficiency disorder allows
blood to leak back through the valve into the heart.
During atrial fibrillation, the heart's two small upper chambers quiver
instead of beating effectively. Blood isn't pumped completely out
of them, so it may pool and clot. If a piece of a blood clot in the atria
leaves the heart and becomes lodged in an artery in the brain, a stroke
results. About 15 percent of strokes occur in people with atrial fibrillation.
The likelihood of developing atrial fibrillation increases with age. Three
to five percent of people over 65 have atrial fibrillation.
