Purpose of review: This article explores recent developments in left main revascularization, with a focus on appraising the latest American and European guidelines.
Recent findings: Recent pooled data analysis from four major randomized controlled trials (RCTs) for left main coronary artery stenosis indicate an advantage for CABG over PCI in regard to freedom from major adverse cardiovascular events, despite no significant difference in mortality observed at 5 years. Additional data support the use of CABG for patients with left ventricular dysfunction, complex left main lesions, diffuse coronary disease, and diabetes.
Summary: The data underpinning the guidelines on each revascularization modality (PCI versus CABG) must consider factors such as lesion complexity, diabetes, and left ventricular dysfunction. Additionally, the findings of the four major RCTs upon which the guidelines are based must be ascertained in light of the latest advancements in these revascularization techniques.
