Coronary artery disease often progresses more rapidly in diabetics, but the integrated impact of diabetes and early revascularization status on late or repeat revascularization in the contemporary era is less clear. Coronary angiography was performed in 12,420 patients between the years 2000–2015 and early revascularization status [none, percutaneous coronary intervention (PCI) or bypass surgery (CABG)] was determined. Subsequent revascularization procedures were recorded over a median follow-up of 67 months and its relation to diabetic and baseline revascularization status was studied. Early revascularization status was none in 5391, PCI in 5682 and CABG in 1347 patients. Late revascularization rates were 10, 26 and 11.1% respectively. Diabetes was present in 37%; a stepwise relationship of diabetic status with late revascularization was observed: no diabetes (reference) 14.4%, non-insulin treated diabetes 21% (adjusted HR 1.35, 95% CI 1.23–1.49, p < 0.001) and insulin-treated diabetes 32.8% (adjusted HR 2.20, 95% CI 1.91–2.54, p < 0.001), which was similar in magnitude for each early revascularization state (none, PCI or CABG). Further revascularizations (≥ 2) were also significantly more common in diabetics, in particular if insulin-treated. Glycosylated hemoglobin level was moderately associated with late revascularization in diabetics after early PCI but not following diagnostic catheterization or CABG. Diabetic status graded by treatment, and in particular insulin therapy, is a strong predictor for late or repeat revascularization irrespective of early revascularization status. The high rate of repeat revascularization in diabetics following PCI remains a challenging issue.

BACKGROUND: Evidence regarding prosthesis–patient mismatch (PPM), measured (mPPM), and predicted (pPPM), after transcatheter aortic valve replacement in bicuspid aortic valve stenosis remains limited. This study sought to evaluate the incidence, predictors, and prognostic implications of mPPM and pPPM in patients with Sievers type 1 bicuspid aortic valve undergoing transcatheter aortic valve replacement. METHODS: The AD-HOC registry is a retrospective, multicenter study including 781 patients with severe aortic stenosis and bicuspid aortic valve treated with transcatheter aortic valve replacement between 2016 and 2023 across 24 centers. PPM was defined according to Valve Academic Research Consortium-3 criteria. The primary outcome was all-cause mortality. RESULTS: Moderate-to-severe mPPM was more frequent than pPPM (22% versus 8%; P <0.001). Balloon-expandable valves were independently associated with both mPPM and pPPM, while smaller valve size and supra-annular sizing predicted only pPPM. During a mean follow-up of 621±470 days, neither mPPM nor pPPM was associated with mortality in the overall cohort. Among patients with a small annulus (≤430 mm ² ; n=145), pPPM occurrence was significantly higher (19% versus 5.5%; P <0.001) and was associated with increased all-cause mortality, but not with cardiovascular mortality. CONCLUSIONS: In patients with Sievers type 1 bicuspid aortic valve undergoing transcatheter aortic valve replacement, pPPM occurred less frequently than mPPM and was predominantly driven by anatomic characteristics and sizing strategies. Although pPPM was associated with increased all-cause mortality among patients with small annuli, this association did not extend to cardiovascular mortality and should be considered hypothesis-generating. Further prospective investigations are warranted to better delineate the impact of anatomic constraints on clinical outcomes in this anatomically challenging subset.
