Abstract
• Probe malfunction during TEE is an underrecognized problem. • MR severity assessment: host (e.g., BP), technical (e.g., gain), probe malfunction. • Clues for malfunction 1: disparity between TTE and TEE; CW and color Doppler. • Clues for malfunction 2: unexplained poor image quality; need for high gain. • Transducer temperature can affect image quality.
摘要
• 经食管超声心动图（TEE）检查期间探头故障是一个未得到充分认识的问题。
• 二尖瓣反流（MR）严重程度评估：主体因素（如血压）、技术因素（如增益）、探头故障。
• 故障线索1：经胸超声心动图（TTE）与TEE之间存在差异；连续波（CW）与彩色多普勒。
• 故障线索2：图像质量莫名变差；需要高增益。
• 换能器温度会影响图像质量。
