Background: The outcomes of percutaneous intervention (PCI) in saphenous vein grafts (SVG) are worse than de novo lesions in native coronary arteries. The long-term mortality rate has been as high as 50% in small trials and meta-analyses of randomized controlled trials have found a mortality rate of 20%. The aim of this study was to evaluate long-term mortality in patients receiving PCI to SVG from a large, real-world database.
Methods: We retrospectively analyzed patients who underwent first intervention to an SVG from 2000 to 2016. Baseline characteristics, clinical presentation, procedural characteristics, and long-term mortality were obtained.
Results: A total of 1,046 patients underwent PCI to SVG. Among those, 20.9% presented with stable ischemic heart disease, 53.2% with unstable angina, and 16.5% with myocardial infarction. Overall, 61% were treated with a drug-eluting stent and 29.3% received a bare metal stent. The overall mortality at 6 months, 12 months, and 3 years was 7.3%, 10.0%, and 23%, respectively.
Conclusions: The majority of patients undergoing PCI of SVG present with stable ischemic symptoms or unstable angina. The short- and long-term mortality rates are high and worse than those in treatment of native coronary arteries.
