Evaluation on left ventricular volume and systolic function with three-dimensional echocardiographic automated algorithm in patients with coronary heart disease after percutaneous coronary intervention / 中国医学影像技术

ABSTRACT

Objective: To evaluate left ventricular systolic function in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) with three-dimensional echocardiographic automated algorithm (3DEA). Methods: Fifty patients with CHD were enrolled. Left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV) and ejection fraction (LVEF) were measured before PCI and 1 month and 3 months after PCI by using 3DEA and two-dimensional biplane Simpson's (2DBP) methods. Results: LVEDV,LVESV and LVEF measured with 3DEA significantly correlated with those with 2DBP (r=0.92, 0.90, 0.84). Compared with measurements before PCI, LVEDV and LVESV measured with 3DEA and 2DBP methods decreased, while LVEF increased 1 month and 3 months after PCI (all P0.05). The time of 3DEA was short, and the reproducibility was higher than that of 2DBP (both P<0.05). Conclusion: 3DEA method is rapid and highly reproducible and highly correlated with 2DBP, therefore may be a useful technique in serially following patients with CHD and assessing responses to PCI.
