Abstract

The cavitation phenomenon is caused by the local pressure depression that occurrs during the closure and/or opening of prosthetic valve leaflets. Occasionally, peculiar features of echocardiographic images generated by cavitation can simulate a mass or vegetation, and are a potential source of diagnostic error. A clinical case that illustrates this phenomenon is described.

摘要

空化现象是由人工瓣膜小叶关闭和/或打开期间出现的局部压力降低引起的。偶尔，由空化产生的超声心动图图像的特殊特征可模拟肿块或赘生物，并且是诊断错误的潜在来源。本文描述了一个说明这种现象的临床病例。
