In our study complications were most commonly found with osteal
and Proximal LAD disease.

In the coronary angiography, besides non-significant LAD osteal
stenosis and 70% mid RCA stenosis (Fig.
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.
Orthogonal axial and single oblique coronal views were used to reconstruct an oblique sagittal view, which was used to measure the maximum and minimum diameter along with perimeter and osteal
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.
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.
Electro-anatomic mapping of the patient was concordant with preceding multidetector 3-dimensional computerized tomography imaging which depicted an unusual PV anatomy involving a common trunk on the left side, a supernumerary middle right PV and a right top (measured osteal
diameter 10 mm) PV anomaly (Fig.
