| :: Introduction|| |
Usefulness of echocardiography it detecting the prosthetic valve function: has been described by many authors. ,, Varying patterns of echoes from the same type of a prosthetic valve have caused confusion in assessing the exact status of the valve function. In this case report, an echocardiogram obtained from prosthetic Bjork Shiley valve is reported and multiple echoes in left atrial cavity probably originating from the left atria. thrombus are demonstrated.
| :: Case report|| |
G. M., a 20 year old female was attending cardiology clinics since 1970. Her main complaints were effort intolerance, palpitations and failure to gain weight, There was history of rheumatic joint pains in the past. Clinical examination revealed moderately severe mitral regurgitation of rheumatic etiology. The patient was subjected to mitral valve replacement by prothetic Bjork Shiley valve in 1977. One year later she was readmitted with low output syndrome and cardiac failure, which did not respond to medical line of treatment. She died in April 1978.
Her prosthetic mitral valve echogram showed an apparently normal functioning of the valve (See [Figure 1] on page 250A) whereas the left atrial cavity was full of thick dense echoes probably from blood clots (See [Figure 2] on page 250A). Interventricular septum showed paradoxical systolic anterior motion.
| :: Discussion|| |
Various echograms obtained from a Bjork Shiley disc valve in mitral valve position have been described by Douglas et al  Our case shows type D pattern  (See [Figure 1], on page 250A). We are unable to state whether this reflected a malfunctioning valve. The interventricular septum showed systolic anterior motion (SAM). Left atrial cavity was full of echoes probably originating from blood clots Since post mortem studies are lacking in this case the status of valve function could not be commented upon.
