A53 year-old patient without any documented cardiac disease admitted to ouroutpatient clinic with exertional angina pectoris (for 6 weeks) and presyncopeoccured a week ago. He is nondiabetic and ex-smoker. Previous anterior myocardial infarction was shown on electrocardiography (ECG, figure 1). Because he wasstable, an elective coronary angiography has been ordered. Aspirin andbetablocker have been prescribed.
On ECG, frequent premature ventricular beats and precordial biphasic T-waves have been shown (Figure 1). Biochemical tests were unremarkable. On echocardiography,apical hipokinesia was detected and EF was 0.50.
Oncoronary angiography, there was total occlusion of left anterior descendingartery (LAD) at distal portion with retrograde filling with bridge collaterals (video 1). There was slight tapering in the proximal and distal main vessel (before and after side branch). Other coronary arteries were shown to have minimal disease.
