| 目的 探讨实时三平面超声心动图(RT-3PE)定量评价二尖瓣反流的临床价值。方法 依据左室造影瓣膜反流程度,将40例二尖瓣反流患者分为Ⅰ、Ⅱ、Ⅲ、Ⅳ四组,同时应用RT-3PE技术测量二尖瓣彩色反流束容积/左房容积(RJV/LAV)、血流汇聚法测量反流分数(RF)以及二维彩色多普勒面积法测量最大反流束面积/左心房面积(RJA/LAA),所得数值进行相应分级并与左室造影分级进行比较。结果 40例二尖瓣反流患者中,12例为偏心性反流,28例为中心性反流。与左室造影相比,RT-3PE对于二尖瓣反流程度Ⅰ、Ⅱ、Ⅲ、Ⅳ级的判断符合率分别为100%、78%、80%、85%(Kappa值79.87%);FC法分别为86%、67%、78%、79%(Kappa值69.88%);RJA/LAA法分别为86%、67%、63%、69%(Kappa值60%)。在12例偏心性反流中,RT-3PE法低估3例,符合率为75%;FC法低估3例、高估2例,符合率为58%;RJA/LAA低估6例,符合率为50%。结论 RT-3PE为定量评价二尖瓣反流、特别是偏心性二尖瓣反流提供了一种简便、准确的方法。 |

| Objective To assess the clinical feasibility of quantitative evaluation of mitral regurgitation by real-time tri-plane echocardiography (RT-3PE). Methods Forty patients with mitral regurgitation were assigned to 4 groups based on the angiographic regurgitation degree. Meanwhile, the regurgitation jet volume/left atrium volume (RJV/LAV) by RT-3PE, the regurgitation fraction (RF) by 2-dimensional color Doppler flow convergence (FC) method and the maximal regurgitation jet area/left atrium area (RJA/LAA) by 2-dimensional color Doppler were also obtained and their semi-quantitative classification was compared with angiographic classification. Results Of 40 patients, 12 had eccentric jets and 28 had central jets. Compared with angiographic degree of mitral regurgitation, the coincidence of Ⅰ, Ⅱ, Ⅲ, Ⅳ degree were 100%, 78%, 80%, 85% by RT-3PE (Kappa value=79.87%), 86%, 67%, 78%, 79% by FC (Kappa value=69.88%), and 86%, 67%, 63%, 69% by RJA/LAA(Kappa value=60%) respectively. Of 12 patients with eccentric jets, the coincidence by RT-3PE was 75% with 3 underestimated, that by FC was 68% with 3 underestimated and 2 overestimated, and that by RJA/LAA was 50% with 6 underestimated. Conclusion RT-3PE is a convenient, accurate and reliable modality in quantitative evaluation for mitral regurgitation, especially for eccentric regurgitation jets. |
