Flow Pattern of Four Pulmonary Veins in a Case with Prolapsing Left Atrial Myxoma

The authors report the flow pattern of the four pulmonary veins in a case with prolapsing left atrial myxoma. The early systolic flow was reversed, midsystolic forward flow was diminished, and diastolic forward flow was augmented and decelerated rapidly in all four pulmonary veins. This phenomenon is attributed to the dynamic movement of the myxoma.
