【摘要】：目的应用经食管实时三维超声心动图(RT-3D-TEE)对非瓣膜病性房颤(NVAF)患者的二尖瓣进行定量研究,探讨NVAF对二尖瓣结构及功能的影响。方法选取20例窦性心律的健康对照组(A组),39例阵发性房颤(PaAF)组(B组)及15例持续性房颤(PeAF)组(C组)行RT-3D-TEE检查,测量并分析左房前后径(LAD)、瓣环左右径(DAlPm)、前后径(DAP)、高度(H)、周长(C3D)、面积(A2D)、瓣环非平面角度(NPA)、对合面积、对合指数。结果与A组比较,B组DAlPm、C3D、A2D、LAD增大(P0.05),C组DAlPm、DAP、C3D、A2D、LAD增大,对合指数减小(P0.05)。B组与C组比较,各参数及LAD差异均无统计学意义(P0.05)。LAD与DAlPm、DAP、C3D、A2D呈显著正相关(r=0.718,P=0.000;r=0.347,P=0.004;r=0.602,P=0.000;r=0.548,P=0.000),与对合指数呈显著负相关(r=-0.319,P=0.008)。结论左房大小与二尖瓣参数显著相关,RT-3D-TEE技术能够定量评价NVAF患者的二尖瓣结构及功能。
[Abstract]:Objective to investigate the effect of NVAF on mitral valve structure and function in patients with non-valvular atrial fibrillation (NVAF) by transesophageal real-time three-dimensional echocardiography (RT-3D-TEE). Methods 20 cases of healthy control group (group A), 39 cases of paroxysmal atrial fibrillation (PaAF) group (group B) and 15 cases of persistent atrial fibrillation (PeAF) group) (group C) were selected for RT-3D-TEE examination. Left atrial anterior and posterior diameter (LAD), was measured and analyzed. Annulus left and right (DAlPm), anteroposterior diameter (DAP), height (H), perimeter (C3D), area (A2D), annular nonplanar (NPA), involutive area, involutive index. Results compared with group A, the DAlPm,C3D,A2D,LAD of group B increased (P0.05), C group increased DAlPm,DAP,C3D,A2D,LAD, the involutive index decreased (P0.05). B group compared with C group, P0.05). There was no significant difference in all parameters and LAD (P0.05) between). LAD and DAlPm,DAP,C3D,A2D (r = 0.718, P = 0.000). There was a significant negative correlation with the involutive index (r = -0.319p ~ (0.008), and a significant negative correlation was found between the two groups (r = 0.347a, P = 0.004, P ~ (0.602) ~ (0.000) ~ 0.548p ~ (0.000), and negatively correlated with the involutive index. Conclusion left atrial size is significantly correlated with mitral valve parameters. RT-3D-TEE can quantitatively evaluate mitral valve structure and function in patients with NVAF.
