Due to newly developed techniques contrast echocardiography (CE) is less often applied today. As to reevaluate the usefulness and the indications for CE 7823 consecutive echocardiographic studies were analysed. In 638 (8%) of these studies CE was used. 379 patients showed signs of right ventricular overload, 58 due to a left-to-right shunt. Pressure overload due to pulmonary hypertension was found in 321 cases. CE enhanced doppler flow signals in tricuspid regurgitation and facilitated quantification of right heart dimensions. 259 patients were screened for patent foramen ovale (PFO), 94 after embolic events, and 165 because neurosurgical intervention in a sitting position was planned. So CE proved to be still indicated in the era of color flow doppler, especially for the detection of PFO.
由于新开发的技术，如今对比超声心动图（CE）的应用频率较低。为了重新评估CE的实用性和适应证，对7823例连续的超声心动图研究进行了分析。在这些研究中，638例（8%）使用了CE。379例患者出现右心室负荷过重的体征，其中58例是由于左向右分流。321例发现由肺动脉高压导致的压力负荷过重。CE增强了三尖瓣反流中的多普勒血流信号，并有助于对右心尺寸进行量化。对259例患者进行了卵圆孔未闭（PFO）筛查，94例是在发生栓塞事件后，165例是因为计划进行坐位神经外科手术。因此，在彩色血流多普勒时代，CE仍然被证明是有适应证的，特别是用于检测PFO。
