Key result
Percutaneous coronary intervention yielded similar mortality and MI rates to MIDCAB, but higher repeat revascularization, with a composite RR of 1.81 (95% CI 0.80-4.06; p=0.15).
Why the study?
Does percutaneous coronary intervention reduce the composite of mortality, myocardial infarction, and target vessel revascularization compared to minimally invasive direct coronary bypass grafting in patients with isolated proximal left anterior descending artery stenosis?
Meta-Analysis (n=711)
Does percutaneous coronary intervention reduce the composite of mortality, myocardial infarction, and target vessel revascularization compared to minimally invasive direct coronary bypass grafting in patients with isolated proximal left anterior descending artery stenosis?
Relative Risk: 1.81 (95% CI 0.8–4.06)
p-value: p=0.15
PCI with bare metal stents and MIDCAB have similar mortality and MI rates for isolated proximal LAD stenosis, but MIDCAB is associated with significantly lower rates of repeat revascularization.

Comparable composite outcomes support either PCI or MIDCAB for proximal LAD stenosis; extends evidence on revascularization trade-offs.
Jaffery et al. (2007) conducted a meta-analysis in isolated proximal left anterior descending artery stenosis (n=711). Percutaneous coronary intervention (PCI) vs. Minimally invasive direct coronary bypass grafting (MIDCAB) was evaluated on composite end point of mortality, myocardial infarction and target vessel revascularization (RR 1.81, 95% CI 0.80, 4.06, p=0.15). Percutaneous coronary intervention yielded similar mortality and MI rates to MIDCAB, but higher repeat revascularization, with a composite RR of 1.81 (95% CI 0.80-4.06; p=0.15).
