title: Doppler evaluation of a left atrial myxoma.
abstract: We present a detailed Doppler evaluation of a left atrial myxoma. Doppler recordings varied considerably with the position of the patient and of the sample volume. Maximum obstruction to flow was observed in the left lateral position; but no gradient was present when sitting upright. These findings provide a haemodynamic explanation for the positional variation of murmurs characteristic of atrial myxomas.
