The "No-touch" Harvesting Technique Revives the Position of the Saphenous Vein as an Important Conduit in CABG Surgery: 30-year Anniversary

Coronary Artery Bypass Surgery: Evidence-Based Practice

Coronary artery bypass graft (CABG) surgery remains a pivotal cornerstone, offering established symptomatic alleviation and prognostic advantages for patients grappling with complex multivessel and left main coronary artery diseases. Despite the lucid guidance laid out by contemporary guidelines regarding the choice between CABG and percutaneous coronary intervention (PCI), a notable hesitation persists among certain patients, characterized by psychological reservations, knowledge gaps, or individual beliefs that sway their inclination toward surgical intervention. This comprehensive review critically synthesizes the prevailing guidelines, modern practices, and outcomes pertaining to CABG surgery, delving into an array of techniques and advancements poised to enhance both short-term and enduring surgical outcomes. The exploration encompasses advances in on-pump and off-pump procedures, conduit selection strategies encompassing the bilateral utilization of internal mammary artery and radial artery conduits, meticulous graft evaluation methodologies, and the panorama of minimally invasive approaches, including those assisted by robotic technology. Furthermore, the review navigates the terrain of hybrid coronary revascularization, shedding light on the pivotal roles of shared decision-making and the heart team in shaping treatment pathways. As a comprehensive compendium, this review not only navigates the intricate landscape of CABG surgery but also aligns it with contemporary practices, envisioning its trajectory within the evolving currents of healthcare dynamics.

For patients with prior coronary artery bypass grafting and recurrent myocardial ischemia, percutaneous coronary intervention on bypass graft or native coronary artery?-A 5-year follow-up cohort study

BACKGROUND

Real-world data on target vessel of percutaneous coronary intervention (PCI) for patients with prior coronary artery bypass grafting (CABG) was still limited.

HYPOTHESIS

A prospective cohort was examined to determine the frequency and outcomes of native coronary artery PCI versus bypass graft PCI in patients with prior CABG.

METHODS

A large-sample observational study enrolled a total of 10 724 patients with coronary artery disease (CAD) underwent PCI in 2013. Two- and five-year clinical outcomes were compared between graft PCI group and native artery PCI group in patients with prior CABG.

RESULTS

A total of 438 cases had CABG history in the total cohort. Graft PCI group and native artery PCI group accounted for 13.7% and 86.3%, respectively. The rates of 2- and 5-year all-cause death and major adverse cardiovascular and cerebral events (MACCE) showed no significant difference between the two groups (p > .05). Two-year revascularization risk was lower in graft PCI group than native artery PCI group (3.3% and 12.4%, p < .05), but 5-year myocardial infarction (MI) risk was higher (13.3% and 5.0%, p < .05). In multivariate COX regression models, graft PCI group was independently associated with lower 2-year revascularization risk (hazard ratio [HR]: 0.21; 95% confidence interval [CI]: 0.05-0.88; p = .033), but higher 5-year MI risk than native artery PCI group (HR: 2.61; 95% CI: 1.03-6.57; p = .042). Five-year all-cause death and MACCE risk showed no difference between the two groups in model.

CONCLUSIONS

In patients with prior CABG underwent PCI, patients in graft PCI group had higher 5-year MI risk than patients received native artery PCI. But, 5-year mortality and MACCE was not significantly different between graft PCI group and native artery PCI group.
