Prosthetic heart valve (PHV) dysfunction is a rare, but potentially life-threatening, complication. In clinical practice, PHV dysfunction poses a diagnostic dilemma. Echocardiography and fluoroscopy are the imaging techniques of choice and are routinely used in daily practice. However, these techniques sometimes fail to determine the specific cause of PHV dysfunction, which is crucial to the selection of the appropriate treatment strategy. Multidetector-row CT (MDCT) can be of additional value in diagnosing the specific cause of PHV dysfunction and provides valuable complimentary information for surgical planning in case of reoperation. Cardiac magnetic resonance imaging (CMR) has limited value in the evaluation of biological PHV dysfunction. In this Review, we discuss the use of established imaging modalities for the detection of left-sided mechanical and biological PHV dysfunction and discuss the complementary role of MDCT in this context.
人工心脏瓣膜（PHV）功能障碍是一种罕见但可能危及生命的并发症。在临床实践中，PHV 功能障碍构成了诊断难题。超声心动图和荧光透视是首选的影像学技术，在日常实践中常规使用。然而，这些技术有时无法确定 PHV 功能障碍的具体原因，这对于选择适当的治疗策略至关重要。多排螺旋 CT（MDCT）在诊断 PHV 功能障碍的具体原因方面具有额外的价值，并为再次手术时的手术计划提供有价值的补充信息。心脏磁共振成像（CMR）在评估生物 PHV 功能障碍方面的价值有限。在这篇综述中，我们讨论了用于检测左侧机械和生物 PHV 功能障碍的既定成像方式，并讨论了 MDCT 在这方面的补充作用。
