Transient mitral regurgitation due to mitral valve prolapse accompanied by systolic anterior motion of the mitral valve
Kanji Iga M.D., Kenjiro Hori M.D., and Shuichi Takahashi M.T.*
A grade 4/6 systolic murmur, systolic anterior motion of the mitral
valve (SAM) and severe mitral regurgitation (MR) documented by two-dimensional
Doppler echocardiography developed suddenly on the structurally normal heart
of a patient with idiopathic portal hypertension. The patient does not
have signs of congestive heart failure and the aforementioned phenomenon
disappeared completely when the patient was in hepatic failure. This could
be explained by a change in circulating blood volume either by gastrointestinal
hemorrhage or hepatic failure.
