| Popis: | In a patient with obstructive left atrial myxoma, we analyzed by pulsed Doppler echocardiography the flow pattern through the mitral valve and in the pulmonary veins. Two mitral flow patterns were observed: the first was present near the medial commissure and along the anterior leaflet and was characterized by the absence of mid-to-late diastolic filling flow; the second was found near the lateral commissure and was characterized by the obstruction of mid-to-late diastolic filling flow, mimicking mitral stenosis. The pulmonary vein flow showed brief and rapidly decelerating anterograde diastolic flow wave and an early systolic retrograde flow wave. These waves were respectively related to the diastolic forward and the systolic backward movement of the tumor. This case report shows that pulmonary vein flow analysis may give new insights into left atrial filling and emptying dynamics in left atrial myxoma. |
