【Abstract】 AIM: To evaluate normal and infarction myocardium by electromechanical mapping system or left ventricular angiography. METHODS: Eight swine were mapped by NOGA and left ventricular angiography before and after embolization of left anterior descending. RESULTS: Threedimensional images of left ventricule obtained by NOGA were consistent with LAO and RAO left ventricular angiography in normal myocardium. In infarction myocardium, the threedimensional images of left ventricle obtained by NOGA were also consistent with LAO and RAO left ventricular angiography. NOGA system could differentiate ischemic myocardium from infarct myocardium whereas left ventricular angiography could not. CONCLUSION: NOGA system can obtain threedimensional images of left ventricle and differentiate ischemic myocardium from infarct myocardium.
