Patients and SVG-Intervention Procedure (
DER, DEGENERATION, DEGENERATED, PLAQUE
From Jan 2012 to Jan 2018, we performed 131 SVG interventions with DES stents in 108 patients at our institution. One patient receiving one procedure was lost to follow-up within the BExS group. An all-comers retrospective analysis was performed dividing these patients into two groups according to treatment (operator dependent): Group SExS mainly received (91.8%) second generation SExS (STENTYS-SES®; Xposition S®, nitinol alloy, sirolimus coated, cell area of 0.95 mmPatients who had received BMS, drug eluting balloon, or plain old balloon angioplasty (POBA) for SVG treatment were not included in the trial.To analyze and quantify the plaque burden of the degenerated SVG, we used the SVG degeneration score analysis according to a predictive model [The study was approved by the local ethics committee (Ethikkommision bei der Landesärztekammer Hessen, FF 125/2012) and previously registered (clinical registration number DE-ST2012-01; DEusches Sizing Register–DEUS).All participants provided informed written consent.
