Signs and Symptoms

Some collateral vessels are small and are found incidentally during an echocardiogram, a test that uses sound waves to create a moving picture of the heart. In other cases, collateral vessels may cause a heart murmur that is detected by a doctor.

The condition also may be identified as the cause of other heart problems, such as myocardial ischemia, an insufficient blood supply to the middle muscular layer of the heart wall; congestive heart failure or the weakening of the heart; endocarditis, an infection of the heart's inner lining; stroke, caused by a lack of blood to the brain; and aneurysms, which are bulging or ballooning of a blood vessel wall.
