Abstract:
Objective To investigate the source of the blood flow through ventricular septum in normal subject caused by slice-thickness artifact in echocardiography. Methods Echocardiography was performed in 50 normal subjects without ventricular septum defect by two models of echocardiography unit equipped with two models of transducer, observing the conditions and sections in which the blood flow through ventricular septum could be detected. Results The blood flow through ventricular septum was detected in 8 normal subjects using the certain model of echocardiography unit,especially in parasternal four chambers section and parasternal irregular sections, while the blood flow through ventricular septum wasn't detected in the other 42 subjects by any echocardiography unit. The blood flow through ventricular septum was caused by coronary vessel in atrioventrieular groove proved by combining dynamic observation with anatomy analysis. Conclusions The blood flow through ventricular septum in normal subjects, a kind of slice-thickness artifact in echocardiography,is caused by coronary vessel in atrioventricular groove mapped into intact ventricular septum.
