The 'water-wheel' or 'mill-wheel' murmur is classically associated with large intracardiac air emboli and described as a "characteristic splashing auscultatory sound due to the presence of gas in the cardiac chambers." We used 64-slice computed tomography (slice thickness, 0.5 mm; revolution time, 400 msec) and 3D fly-through software imagery to capture previously unreported intracardiac air-blood interface dynamics associated with this murmur and ineffective right ventricular contraction in a porcine model.
“水车样”或“磨盘样”杂音通常与心腔内大量空气栓子相关，被描述为“由于心腔内存在气体而产生的特征性溅泼样听诊音”。我们使用64层计算机断层扫描（层厚0.5毫米；旋转时间400毫秒）和三维透视软件成像，以捕捉猪模型中与这种杂音及右心室无效收缩相关的、此前未报告的心腔内气血界面动态变化。
