چکیده
The optimal revascularization strategy for multivessel coronary artery disease remains controversial, especially when there is diffuse disease involving the proximal segment of the left anterior descending artery (LAD). Coronary artery bypass graft surgery (CABG) remains the gold standard approach, although the evidence is increasingly being challenged by technological and procedural advances in percutaneous coronary intervention (PCI). The well-established survival benefit of surgery1–3 is conferred by the left internal mammary arterial (LIMA) graft to the LAD, which, through its resistance to thrombosis and atherosclerosis,4 has demonstrated patency rates of 95% to 98% at 10 years.5,6 Moreover, the LIMA has been shown to protect the proximal LAD territory against further ischemic injury from progressive disease.4 However, the incremental benefit of concomitant saphenous vein grafts (SVGs) supplying non-LAD territories is less clear.2,3 The longevity of vein grafts is relatively poor, with reported failure rates averaging 20% at 1 year and reaching up to 70% at 15 years.6–8 Interestingly, the Project of Ex-vivo Vein graft Engineering via Transfection IV (PREVENT IV) trial investigators reported an SVG failure rate of 45% at 12to 18-month angiographic follow-up,7 a figure that, in the modern era, seems unacceptable.

Both coronary artery bypass grafting (CABG) surgery and percutaneous coronary intervention (PCI) have been shown to provide symptomatic relief and to increase longterm survival in patients with coronary artery disease.1–3 Hybrid coronary revascularization (HCR) seeks to combine the respective strengths of CABG and PCI in an attempt to offer a technique that is less invasive than conventional su...
متن کاملCharacterizing the Validity and Real-World Utility of Health Technology Assessments in Healthcare: Future Directions; Comment on “Problems and Promises of Health Technologies: The Role of Early Health Economic Modelling”
With their article, Grutters et al raise an important question: What do successful health technology assessments (HTAs) look like, and what is their real-world utility in decision-making? While many HTAs are published in peer-reviewed journals, many are considered proprietary and their attributes remain confidential, limiting researchers’ ability to answer these questio...
