Impact of Lesion Preparation Strategies on Outcomes of Left Main PCI: The EXCEL Trial

N Beohar, S Chen, GW Stone et al. Keywords: lesion preparation left main coronary artery; PCI

ABSTRACT

OBJECTIVES - We examined outcomes according to lesion preparation strategy (LPS) in patients with left main coronary artery (LMCA) percutaneous coronary intervention (PCI) in the EXCEL trial.

 

BACKGROUND - The optimal LPS for LMCA PCI is unclear.

 

METHODS - We categorized LPS hierarchically (high to low) as: (a) rotational atherectomy (RA); (b) cutting or scoring balloon (CSB); (c) balloon angioplasty (BAL); and d) direct stenting (DIR). The primary endpoint was 3year MACE; allcause death, stroke, or myocardial infarction.

 

RESULTS - Among 938 patients undergoing LMCA PCI, RA was performed in 6.0%, CSB 9.5%, BAL 71.3%, and DIR 13.2%. In patients treated with DIR, BAL, CSB, and RA, respectively, there was a progressive increase in SYNTAX score, LMCA complex bifurcation, trifurcation or calcification, number of stents, and total stent length. Any procedural complication occurred in 10.4% of cases overall, with the lowest rate in the DIR (7.4%) and highest in the RA group (16.1%) (p trend = .22). There were no significant differences in the 3year rates of MACE (from RA to DIR: 17.9%, 20.2%, 14.5%, 14.7%; p = .50) or ischemiadriven revascularization (from RA to DIR: 16.8%, 10.8%, 12.3%, 14.2%; p = .65). The adjusted 3year rates of MACE did not differ according to LPS.

 

CONCLUSIONS - The comparable 3year outcomes suggest that appropriate lesion preparation may be able to overcome the increased risks of complex LMCA lesion morphology.
