After a long wait, contrast echocardiography is at last becoming a reality. The experimental validation step has been passed with success and the first clinical results bring confirmation. The second generation contrast agents which are arriving on the market, and the spread of enhancement techniques such as Real-Time mode allow perfect visualisation of microbubbles within the left ventricular cavity, but equally at the level of the myocardial crown, thus targeting two direct applications in echocardiography: the first, indisputably, concerns the improvement in the detection of the endocardium in all the situations where it is insufficient, and in particular during stress echography; the second, more ambitious, confronts the study of myocardial perfusion, with a yet to be defined place in clinical practice.
经过漫长等待，超声心动造影终于成为现实。实验验证阶段已成功通过，首批临床结果也证实了这一点。第二代造影剂已投放市场，实时模式等增强技术的普及使得左心室内微泡得以完美可视化，同样在心肌表层水平也是如此，从而确定了超声心动造影的两个直接应用领域：其一，毫无疑问，涉及在所有内膜显示不清的情况下，尤其是在负荷超声心动图检查时，改善心内膜的检测；其二，更具雄心的是，涉及心肌灌注研究，其在临床实践中的地位尚待确定。
