Determination of Optimal Fluoroscopic Angulations for Left Main Coronary Artery Ostial Interventions: 3-Dimensional Computed Tomography Validation

Figure 8

(a) Two 0.035-inch wires were advanced to the NCC and RCC using the RAO and CAU view; (b) the lowest points in the curve at the distal part of these two wires were superimposed at LAO 28/CRA 16; (c) the stent was located at the angulation; (d) the image of LMCA after stent deployed at RAO 5/CRA 31; (e) in the poststenting pullback with the speed of one millimeter equal to 60 frames, the LMCA ostium was at frame 595; (f) the stent ostium was at frame 665. So the stent protruded to the aorta for 1.17 mm ((665–595)/60). CAU = caudal; CRA = cranial; LAO = left anterior oblique; RAO = right anterior oblique.
