Abstract：Objective To explore the evaluation value of full-volume three dimensional echocardiography (FV-3DE) in left ventricular regional configuration and systolic function for patients with coronary heart diseases. Methods Altogether 25 cases with coronary heart diseases who were suitable for PCI (Percutaneous Coronary Intervention) and 20 healthy people underwent FV-3DE examinations. QLAB Software was applied to process the three dimensional images so as to obtain complete left ventricle and 17 segment volume-time curve, regional end diastolic volume (REDV), regional end systolic volume (RESV), regional stroke volume (RSV) and regional ejection fraction (REF). The SPSS 13.0 statistics software was applied to compare the categorical variables between two groups. Results (1) Compared with Normal Group, the regional volume-time curve of 17 segments in the left ventricle in Coronary Heart Disease Group was overlap and disorder. Small fluctuation of the ischemic region volume curve was seen. Normal region myocardium local volume was enlarged, which indicated that compensatory constriction was larger. The regional volume-time curve of 17 segments in the left ventricle in Normal Group displayed U shape with orderly arrangements. The volume was decreased form the base of heart to apex of heart. (2) Most of the REDV and RESV of 17 segments in the left ventricle in Coronary Heart Disease Group were more larger than Normal Group; while most of REF in Coronary Heart Disease Group was lower than Normal Group (P<0.05), especially in the anteroseptal, anterior, posterior and apical inferior segments (P<0.05 or P<0.01). Post-PCI RE DV and RESV were reduced compared to pre-PCI patients; while REF was increased to normality, especially in the anteroseptal, anterior, posterior and inferior segments (P<0.05). Conclusion FV-3DE provided a new potential method in assessing left ventricular regional volume and heart functions, which could offer rich and accurate clinical information.
