ABSTRACT
BACKGROUND:
The purpose of this study was to determine the most appropriate measurement of left ventricular (LV) end-diastolic diameter for subjects with the sigmoid septum (SS) by measuring the LV end-diastolic diameter at the base and mid-ventricle and by examining the relationship between these measurements and the three-dimensional (3D) echocardiographic LV end-diastolic volume.METHODS:
In 91 patients who underwent echocardiography for screening cardiovascular abnormalities, the aorto-septal angle (ASA) was measured as an index of the sigmoid septum. LV end-diastolic diameter was measured at the base and mid-ventricular level (DDbase and DDmid, respectively), and their average value was calculated (DDavg). By using 3D echocardiography, LV end-diastolic volume (EDV3D) was measured.RESULTS:
Among 91 patients, 48 patients had narrow ASA (< 120 degrees) and were divided into the sigmoid septum (SS) group, and the remaining 43 patients were divided into the non-SS group. In the SS group, all DDbase, DDmid, and DDavg were significantly correlated with EDV3D (r = 0.59, 0.80, and 0.76, respectively), and the correlation coefficient between DDbase and EDV3D was significantly lower than that between DDmid and EDV3D (p < 0.01). On the other hand, in the non-SS group, all DDbase, DDmid, and DDavg were significantly correlated with EDV3D (r = 0.77, 0.85, and 0.84, respectively), and the correlation coefficient between DDbase and EDV3D was statistically comparable to that between DDmid and EDV3D (p = 0.12). ASA was significantly correlated with the difference of DDmid minus DDbase (r = - 0.71, p < 0.001).CONCLUSIONS:
In patients with SS, DDmid and DDavg were well reflected the 3D echocardiographic LV end-diastolic volume.Palabras clave
