Abstract
• Acoustic shadowing limits Doppler evaluation in PHVs, potentially masking MR. • Spectral Doppler is an important tool to detect prosthetic MR. • TEE can supplement TTE, partially avoiding acoustic shadowing and reverberations.
摘要
• 声影限制了经皮心室辅助装置（PHV）中的多普勒评估，可能掩盖二尖瓣反流（MR）。
• 频谱多普勒是检测人工瓣膜二尖瓣反流的重要工具。
• 经食管超声心动图（TEE）可补充经胸超声心动图（TTE），部分避免声影和混响。
