Mechanical heart valve leads to rare complication

Heart-valve replacement patients presenting with neurological symptoms are at risk, say case report authors

Part of a mechanical heart valve travelled to a patient’s brain creating a metallic embolus — a rare complication, but one doctors need to consider, according to the man’s US physicians.

In the case, the 46-year-old patient had a history of rheumatic heart disease, and underwent mitral and aortic valve replacement with a mechanical and supra-annular valve, respectively.
