Left Main Revascularization
47. ESC guidelines 2010 – CABG vs. PCI
• Left main (isolated or 1VD ,ostium/shaft)
- CABG = IA, PCI = IIa B
• Left main (isolated or 1VD, distal bifurcation)
- CABG = IA, PCI = IIb B
• Left main + 2VD or 3VD,SYNTAX score < 32
- CABG = IA, PCI = IIb B
• Left main + 2VD or 3VD,SYNTAX score 33
- CABG = IA, PCI = III B
* I/IIb/III = recommendation class, A/B = level of evidence
drtoufiq19711@yahoo.com
48. Guidelines summary
• CABG gold standard but PCI good option in
ostial/shaft disease or when SYNTAX ≤ 22 and risk of
surgical complications is relatively high
• PCI also acceptable in high surgical risk patients
with distal LM disease or when SYNTAX ≤ 32
• PCI should not be performed in patients who can
undergo CABG and have unfavourable anatomy
(SYNTAX > 33)

50. PCI and CABG do not work by intention to treat
The most important issue is long term results
In PCI success is “WRONGLY” defined as successful stent placement
Optimal: IVUS confirmed stent placement, should be the gold standard
drtoufiq19711@yahoo.com
51. 1. Occlusion of the LAD or of the RCA which cannot be opened by PCI
and with viable myocardium. Chronic occlusion of the RCA and
sometimes even of the LAD can left untreated in elderly people with
reduced physical activity.
2. Complex and calcific distal left main bifurcation and the PCI
operator does not feel confident to treat or she/he does not expect to
obtain a good final result
3. Long diffuse disease in the proximal LAD (needs a stent longer than
30-35 mm) in a patient with diabetes mellitus
4. A patient who has or may have problems with dual antiplatelet
therapy
Conditions were CABG may be a better choice compared to
PCI in patients with Left Main Stenosis

Investigators
• Applying the knowledge from FAME with SYNTAX
– Anatomy and Physiology
• 497 FAME pts had SYNTAX Score prospectively collected
• Only the “physiologic” significant lesions were scored
• 32% of pts moved to a lower risk group
• Only FSS and procedure time were independent variables of
1-yr MACE

61. Functional SYNTAX Score for Risk Assessment in
Multivessel Coronary Artery Disease
Outcomes by SYNTAX Score
• (A)The rates of death or (MI)
• (B) major adverse cardiac events (MACE),
as composite of death, MI, or repeat
revascularization including repeat PCI or
CABG according to SS and FSS.
• The rate of death or MI was significantly
different in the FSS groups unlike the SS
groups. The rate of MACE was increased
for the highest-risk group
• This trend was attenuated in the FSS
groups compared with the classic SS
groups. *p < 0.01, **p < 0.001.

• Meta-analysis of 24 studies published January
2000 to December 2012, 14,203 patients. No
significant difference for all-cause mortality
between PCI or CABG at 1 year (odds ratio [OR],
0.792; 95% confidence interval [CI], 0.53 to 1.19),
2 years (OR, 0.92; 95% CI, 0.67 to 1.26), 3 years

95% CI, 0.53 to 1.33), and 5 years (OR, 0.79; 95%
CI, 0.57 to 1.08).

65. LMain
• TVR was significantly higher for PCI and stroke
was significantly lower. Nonfatal MI showed a
statistically significant lower trend in CABG
patients at 1 year (OR, 1.62; 95% CI, 1.05 to 2.50),
2 years (OR, 1.6; 95% CI, 1.09 to 2.35), and 3 years
(OR, 2.06; 95% CI, 1.36 to 3.1). There was no
significant difference in combined major adverse
cardiovascular and cerebrovascular events
between the two groups.
• Conclusions: PCI with DES is a safe and durable
alternative to CABG for UPLM stenosis in select
patients at long-term follow-up.

66. Consideration for Left Main PCI
• NERS Score/NERS Score II
– More complicated but potentially more predictive
with reduction of variable from 54 to 16 (Chen,
JACCINTV. 2013; 6:1233-41.
• Guidelines recommendation
• Anatomic Location may be Key
• Heart Team Approach
• EXCEL Trial (2,600 pts, 3 yrs follow-up, DES vs
CABG for LMain.
