Abstract

Embolic events, particularly involving the central nervous system, represent one of the important hazards associated with the implantation of mechanical valves. The use of the transcranial Doppler to insonate the middle cerebral artery has allowed us to detect microembolic events in some of these patients. Patients with long term implantation and frequent microemboli appear to be more prone to transient ischemic attacks or stroke. Evaluation of 26 patients with mechanical valves revealed 14 with detectable microemboli, four of whom experienced central nervous system symptoms. Modifications in the medical or anticoagulant regimes have not been successful in decreasing or eliminating these microemboli. As the transcranial Doppler is a non-invasive means of quantifying these microemboli, it may become a useful tool in identifying those patients in need of a new type of antithrombotic regimen, or even a valve replacement. Transcranial Doppler could thus provide advance warning before a catastrophic cerebral embolism occurs.
