【摘要】：目的探讨彩色多普勒超声心动图(CDE)对老年房间隔缺损(ASD)患者右心室形态及收缩功能的评估价值。方法超声科收治的60例老年ASD患者为ASD组,根据不同的肺动脉收缩压(PASP)将ASD患者分为无肺动脉高压患者(PASP35 mm Hg,低压组)29例和肺动脉高压患者(PASP35 mm Hg,高压组)31例,并选取该院同期体检正常的成人志愿者30例作为对照组。使用实时三维超声心动图(RT-3DE)对研究对象的右心室形态及收缩功能进行检测和分析,分析参数包括:右心室舒张末期内径(RVDD)、右心室舒张末期容积(RVEDV)、右心室收缩末期容积(RVESV)、右心室每搏量(RVSV)、右心室射血分数(RVEF)。结果 ASD组RVDD、RVEDV、RVESV及RVSV均显著高于对照组,而RVEF显著低于对照组(P0.05)。高压组RVDD、RVEDV、RVESV、RVSV显著高于低压组和对照组,RVEF显著低于低压组和对照组,高压组ASD最大直径显著高于低压组(P0.05),低压组RVDD、RVEDV、RVESV、RVSV及RVEF与对照组比较无统计学差异(P0.05)。经Pearson相关分析显示,ASD患者RVEF与患者ASD最大直径、RVDD、RVEDV、RVESV呈负相关(r=-0.387,-0.352,-0.226,-0.302;P=0.015,0.000,0.012,0.023),与RVSV无相关性(r=0.182,P=0.253)。结论 RT-3DE对老年ASD患者的右心室形态及收缩功能评估具有高准确性。
[Abstract]:Objective to evaluate the value of color Doppler echocardiography (CDE) in evaluating right ventricular morphology and systolic function in elderly patients with atrial septal defect (ASD). According to different pulmonary arterial systolic pressure (PASP), the patients with ASD were divided into three groups: PASP35mm Hg without pulmonary hypertension, 29 patients with hypobaric hypertension, 35mm PG with pulmonary hypertension and 31 patients with hypertension. Thirty adult volunteers with normal physical examination were selected as control group. The right ventricular morphology and systolic function were measured and analyzed by real-time three-dimensional echocardiography (RT-3DE). The parameters included right ventricular end-diastolic diameter (RVDDD), right ventricular end-diastolic volume (RVEDVV), right ventricular end-systolic volume (RVESVV), right ventricular volume (RVSVV), right ventricular ejection fraction (RVEFV). Results RVDDV, RVEDVV, RVESV and RVSV in ASD group were significantly higher than those in control group. RVEF was significantly lower than that of control group (P 0.05). The maximum diameter of ASD in the high pressure group was significantly higher than that in the low pressure group (P 0.05). There was no significant difference in RV VSV and RVEF between the low pressure group and the control group. The Pearson correlation analysis showed that there was a negative correlation between RVEF and the maximum diameter of ASD. RT-3DE has high accuracy in evaluating right ventricular morphology and systolic function in elderly patients with ASD.
