Summary
The internal thoracic artery (ITA) is the preferred graft for myocardial revascularization due to superior long-term patency and better clinical outcomes. Despite concerns about early risks, ITA grafts offer improved early results compared to vein grafts.
Area of Science:
- Cardiovascular Surgery
- Vascular Grafting
- Coronary Artery Disease
Context:
- The internal thoracic artery (ITA) is increasingly recognized for its advantages over traditional venous grafts in myocardial revascularization.
- Patient subgroups with complex coronary artery disease (CAD) benefit significantly from ITA grafting.
Purpose:
- To highlight the superior histological, physiological, and pharmacological properties of the ITA compared to venous grafts.
- To advocate for the routine use of ITA grafts in myocardial revascularization, supported by evidence of improved long-term and early clinical outcomes.
Summary:
- The ITA demonstrates excellent long-term patency and a low incidence of late atherosclerotic lesions, making it the graft of choice for myocardial revascularization.
- Clinical results are improved across all patient subgroups, including those with poor left ventricular function, left main stenosis, diffuse CAD, and octogenarians.
- Despite potential concerns regarding slightly higher early morbidity and mortality, the ITA offers superior early operative results compared to vein grafts, challenging reluctance in its routine use.
Impact:
- Routine adoption of ITA grafts can lead to improved patient outcomes and reduced long-term complications in coronary artery bypass grafting.
- This evidence supports a shift in surgical practice towards prioritizing ITA use for myocardial revascularization.
- Further research may address and mitigate any perceived early operative risks associated with ITA grafting.
