Left Main Bifurcation Lesion Treated by Kissing Stent Technique with Cypher Stents: Excellent Immediate and 6-Month Follow-Up Results

- Operator: Seung-Wook Park, MD, Korea
Case presentation
The patient was 56 years old man admitted with unstable angina for 1 month. He was smoker and had hypercholesterolemia. Baseline ECG showed T inversion in V1-V4. Echocardiography showed good LV function with an EF of 54% without regional wall motion abnormality.
Baseline coronary angiography
1. Left coronary angiogram showed a bifurcation lesion with involvement of the ostium of LAD and diffuse stenosis of ramus intermedius (RI) branch (Figure 1).
2. RCA was normal.
Intravascular ultrasound
Left main to LAD were wired with a 0.014 F Floppy wire. IVUS was performed through the wire. IVUS image showed that a significant stenosis at LMCA bifurcation with involvement of the ostial LAD (Figure 2)
Procedure

An 8F sheath was inserted through right femoral artery and the left coronary was engaged with an 8F judkins left catheter. Initially RI branch was treated with a Arthos stent 3.0 mm x 24mm at 12 atm (Figure 3). Left main to LAD and LCX were wired with two 0.014 wires. At this time, we considered ¢®¡Ækissing stenting¢®¡¾ in the ostiums of LAD and LCX with covering the distal LMCA lesion. Kissing stenting technique was performed in the ostial LAD with a 3.0mm x 23mm Cypher stent at 16 atm and the ostial LCX with a 3.0mm x 13mm Cypher stent at 18atm, simultaneously (Figure 4). Additional post-dilation was also performed with kissing balloon technique with the same stent balloons (Figure 5). Final angiography showed well deployed stents in the LAD and LCX in multiple projections (Figure 6, Figure 7).
He was very happy with the result and recurrent did not occur during follow-up period. At 6-month follow-up angiography, patency of the both stents was maintained, which was observed in multiple projections (Figure 8, Figure 9).

  • ±èÁØÈ« 2003-10-31 Wow! Very nice result and really great. I'd like to ask you about the state of LM ostial site after stenting. Did two stents cover the ostium?
  • Seung-Jung Park 2003-11-04 We didn't cover true ostium of the left main, because the IVUS findings showed no plaque burden on the ostial area at the begining of the procedure.
