目的 探讨四维经食管超声心动图(4D-TEE)在瓣膜修复中的作用。 方法 2016 年 1 月我院对 3 例行二尖瓣修复和 1 例行主动脉瓣膜修复的患者采用西门子 SC2000 4D-TEE 进行术前术后评估,其中男 2 例、女 2 例,年龄38~59 (48.0±10.5)岁。同期采用二维经食管超声心动图指导二尖瓣和主动脉瓣修复的 13 例患者作为对照,其中男 8 例、女 5 例,年龄43~67(56.4±7.5)岁。 结果 术中 4D-TEE 可实时显示瓣叶的各项参数,如不同节段瓣叶高度、交界区面积、瓣叶面积、对合面的大小、窦管交界大小,瓣膜运动形态、主动脉管壁位移等信息。可根据内置软件建立个性化的瓣膜几何模型,动态模拟瓣膜启闭并直观呈现。对照组仅可显示某切面的瓣膜、腱索、乳头肌、心腔等信息。 结论 4D-TEE 跳过了对二维图像的解读步骤,更直观完整地显示了瓣膜形态和动态,可以通过它的辅助来进行更有效的手术决策。
