In the coronary angiography, besides non-significant LAD osteal

Patients with osteal
disease with no foot hold, left Ventricular Ejection Fraction less than 25%, left main artery patency less than 50%, coexisting chronic heart failure, valvular heart disease, chronic renal failure, and contraindication to anticoagulation, were excluded.
The ramus showed severe diffuse disease proximally, total occlusion in the obtuse marginal branch of Left Circumflex and 80% osteal
disease in the Posterior Descending Artery.
His coronary angiogram showed 90% discrete, osteal
stenosis of the left main coronary artery and severe proximal LAD disease with mid total occlusion - [Figure 5].
Coronary angiography demonstrated 90% osteal
stenosis of left anterior descending artery, 70% stenosis of left circumflex artery, and 80% stenosis of right coronary artery.
