 Case
summary |
| This 52-year old male
patient was admitted with resting chest pain
for 10 days. Baseline coronary angiogram showed
a diffuse narrowing at the left anterior descending
artery (LAD) artery and a bifurcation narrowing
at the circumflex artery (LCX). |
| Procedural
steps and clinical experience of the Classic
NM Balloon |
| After stenting with
a 3.0 x 28mm Cypher stent in the LAD lesion,
coronary angiogram showed a bifurcation narrowing
at the LCX (Figure
1). We inserted two wires in the
distal LCX and the obtuse marginal branch
(OM). After predilation in the LCX and OM
branch (Figure
2, Figure
3), significant dissection occurred
in the ostium of OM branch (Figure
4). Therefore we intended to treat
the lesion with Stent-Crush technique. After
deploying a 2.75 x 18mm Cypher stent (Figure
5), we removed the stent delivery
system in the OM branch to prevent trap of
the wire during stent deployment in the LCX.
And we deployed a 3.0 x 33mm Cypher stent
towards the LCX (Figure
6). Although following angiogram
showed the successfully deployed stents in
the LAD and the diagonal branch, we tried
to introduce a new balloon system, Classic-NM
balloon system, into the OM branch for final
kissing balloon dilatation. The new balloon
system was easily advanced into the OM branch
without resistance. After final kissing balloon
dilatation (Figure
7), we achieved a very successful
result (Figure
8). We experienced that
the Classic-NM balloon system was a very useful
and appropriate balloon system for very omplex
lesions including bifurcation lesions. |
