Case Presentation |
A 64 year-old male was admitted with effort chest pain for 2 weeks. His coronary risk factors were hypertension and dyslipidemia. The baseline ECG, echocardiography and cardiac markers were not remarkable. But on thallium SPECT, both LAD and LCx territories showed reversible large sized perfusion defects and preserved LV function. |
Baseline Coronary Angiography |

Procedure |
An 8F sheath was inserted through right femoral artery, and the left coronary artery was engaged with an 8F JL catheter with 4.0 cm curve. Two 0.014-inch Sion wires were inserted into the LAD and D1, respectively. D1 was pre-dilated with 2.0 x 20 mm Maverick balloon and a Resolute Integrity stent 2.75 x 15 mm was deployed at D1. (Figure 2) Then we performed crushing with Quantum balloon 3.0 x 20 mm at mLAD. (Figure 3) The D1 wire was removed and repositioned into the LCx proper. ( Movie 3) pLCx was pre-dilated with 2.0 x 20 mm Maverick balloon and a Resolute Integrity stent 3.0 x 26 mm was deployed at pLCx. (Figure 4) Then, we did crushing with a Resolute Integrity stent 3.5 x 38 mm at p-mLAD to LM shaft. (Figure 5) The LCx wire was removed and repositioned into the D1 and Ikazuchi balloon 1.2 x 6 mm, Maverick balloon 2.0 x 20 mm were sequentially used to open the D1 ostium. Using Empira NC balloon 2.75 x 15 mm and Quantum balloon 3.0 x 20 mm, we did final kissing for mLAD bifurcation site. (Figure 6) The D1 wire was removed and repositioned again into the LCx and we did final kissing for proximal LAD and proximal LCx using Quantum balloon 3.5 x 20 mm and Quantum balloon 3.0 x 20 mm, respectively. (Figure 7) Final left angiogram and IVUS showed that the procedure was successful ( Movie 4, Movie 5). |
