To study the application of Doppler tissue imaging (TDI) in the assessment of right ventricular function of patients with intraoperative device closure of atrial septal defect (ASD).
A total of 48 ASD patients, 18 males and 30 females, were selected for intraoperative device closure. The mean age was 31 +/- 16 years old. Color Doppler echocardiographic instrument (Sonos 4500) was employed to perform the Doppler tissue imaging before and at 3-5 days after operation. The parameters included: (1) Time and peak speed of systolic motion of anterior tricuspid valve annulus (TDI-TS, TDI-PVS), early diastole motion time (TDI-TE) and late diastolic motion time (TDI-TA) and peak speed of early and late diastolic motion (TDI-PVE, TDI-PVA), interval between the early diastolic motion and late diastolic motion (TDI-TE-A); (2) Peak speed of systolic, early diastolic and late diastolic motions of the middle lateral and basic lateral walls of right ventricle.
The TDI-PVS (0.16 +/- 0.05) m/s in post-operation was decreased than TDI-PVS (0.20 +/- 0.04) m/s in pre-operation and TDI-PVA (0.12 +/- 0.03) m/s in post-operation was decreased than TDI-PVA (0.16 +/- 0.02) m/s in pre-operation apparently (P < 0.01). The TDI-TS (231 +/- 36) msec in post-operation were shorter than TDI-TS (265 +/- 24) msec in pre-operation (P < 0.01). Peak spead of Systolic, early diastolic and late diastolic motions of middle lateral and basic lateral walls of right ventricle declined post-operatively (P < 0.01).
TDI is an effective method to evaluate the function of right ventricle quantitatively in patients with intraoperative device closure of ASD.
探讨多普勒组织成像（TDI）在房间隔缺损（ASD）术中封堵患者右心室功能评估中的应用。
选取48例ASD患者，其中男性18例，女性30例，进行术中封堵治疗，平均年龄31±16岁。采用彩色多普勒超声心动图仪（Sonos 4500）于术前及术后3 - 5天进行多普勒组织成像检查。参数包括：（1）三尖瓣前叶瓣环收缩期运动时间及峰值速度（TDI - TS、TDI - PVS）、舒张早期运动时间（TDI - TE）、舒张晚期运动时间（TDI - TA）以及舒张早期和晚期运动峰值速度（TDI - PVE、TDI - PVA）、舒张早期与晚期运动的时间间隔（TDI - TE - A）；（2）右心室中间侧壁和基底侧壁收缩期、舒张早期及舒张晚期运动峰值速度。
术后TDI - PVS（0.16±0.05）m/s较术前TDI - PVS（0.20±0.04）m/s明显降低，术后TDI - PVA（0.12±0.03）m/s较术前TDI - PVA（0.16±0.02）m/s明显降低（P < 0.01）。术后TDI - TS（231±36）msec较术前TDI - TS（265±24）msec缩短（P < 0.01）。右心室中间侧壁和基底侧壁收缩期、舒张早期及舒张晚期运动峰值速度术后均下降（P < 0.01）。
TDI是定量评估ASD术中封堵患者右心室功能的有效方法。
