A patient with a dynamic left ventricular outflow murmur was shown to have an anomalous anterolateral papillary muscle by transthoracic and transesophageal two-dimensional Doppler echocardiography. High late systolic outflow velocity and systolic anterior motion were demonstrated in the lateral outflow tract near the anomalous muscle, suggesting a role for the Venturi effect. This is the first confirmation by Doppler echocardiography of an anomalous papillary muscle contributing to abnormal left ventricular hemodynamics.
一名有动态左心室流出道杂音的患者经胸和经食管二维多普勒超声心动图检查显示有异常前外侧乳头肌。在异常乳头肌附近的外侧流出道显示出较高的收缩晚期流出速度和收缩期前向运动，提示存在文丘里效应。这是多普勒超声心动图首次证实异常乳头肌对左心室异常血流动力学有影响。
