 :: Introduction Top

Usefulness of echocardiography it detecting the prosthetic valve function: has been described by many authors. [1],[2],[3] 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 Top

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 Top

Various echograms obtained from a Bjork Shiley disc valve in mitral valve position have been described by Douglas et al [1] Our case shows type D pattern [1] (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.
