Rapid Growth of a Left Atrial Myxoma
--Serial Two-dimensional Echocardiographic observation over 18 Months--
Kanji Iga MD, Chisato Izumi MD,and Takashi Konishi MD
Summary
We encountered a patient with rapid progressing left atrial myxoma in
whom two-dimensional echocardiography was serially obtained over 18 months.
The horizontal and longitudinal diameters showed a linear 2.5-fold increase,
while the size of the base attached to the left atrial wall remained unchanged.
Therefore, the last echocardiogram obtained just before surgery showed the
characteristic pendular motion of left atrial myxoma.
