Case Presentation |
A 73 year-old male was admitted with effortchest pain for 6 months. He underwent CABG (LIMA-LAD, SVG-PDA, tRA-OM) 10 years ago. His coronary risk factors were hypertension, hyperlipidemia, and ex-smoker. The physical examination was normal. His baseline ECG, echocardiography and cardiac markers were unremarkable. |
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. 0.014-inch BMW guide-wire was inserted into the LAD and another 0.014-inch 190cm BMW guide-wire was inserted into the LCX. Proximal LCX was pre-dilated with 2.5 x 20mm BH PLUS balloon. And then, we pre-dilated LM to proximal LAD using 2.5 X 20mm BH PLUS balloon. (Figure 3, Figure 4) An Orsiro 2.75 x 18 mm Stent was successfully deployed at proximal LCX. (Figure 5) Consecutive Orsiro 4.0 x 22 28mm Stents was successfully deployed at LM to proximal LAD by Mini Crush technique. (Figure 6) A 0.014-inch Choice PT guide-wire was exchanged into the LCX. Additional kissing ballooning was performed by using Nimbus Salvo 4.0 x 17mm balloon at LM to proximal LAD and Quantum 2.75 x 15mm balloon at proximal LCX.(Figure 7) Final left angiogram and IVUS showed successful.( Movie 4, Movie 5) |
