Mitral valve prolapse is a common cause of a heart murmur caused by a "leaky" heart valve. Most cases of mitral valve prolapse are not serious and only need to be monitored.
Mitral valve prolapse is associated with many other symptoms and conditions. But experts aren't sure that mitral valve prolapse is what causes them.
When used to detect whether a heart attack is occurring or may occur, SPECT locates areas of the heart muscle that have inadequate blood flow compared with areas that have normal flow. Inadequate blood flow means that coronary arteries are blocked and a heart attack is occurring. SPECT can also assess how bad the blood flow blockage is.
It is a noninvasive imaging scan that exposes you to radiation. For this test, your doctor injects a tiny amount of radioactive tracers through a vein in your arm. After the radioactive tracer is injected, a camera that can detect the radiation emitted by these tracers rotates around you. This creates images of your heart from different angles. Then, computer graphics are used to create three-dimensional images of your heart.
If your SPECT test is abnormal, you are considered at high risk of a heart attack.
