The inflation pressure during stent implantation had no impact on "jailed" guidewire damage. The difference in the prevalence of serious damage and total damage number was statistically significant for the BMW guidewire compared to the Pilot50. The BMW guidewire was an independent predictor of the degree of damage to the guidewire.

BACKGROUND The optimal management of cardiac allograft vasculopathy (CAV) remains unknown. Percutaneous coronary intervention (PCI) has been considered palliative due to high restenosis rates, but still remains an alternative to the definitive therapy of re-transplantation. Drug eluting stents (DES) were shown superior to bare metal stents, and recently bioresorbable scaffolds (BRS) have been proposed, but data are still scarce. lesions in 55 heart transplanted patients (31%female, median age at coronary procedure (PCI) 56.9 years, at transplant 45 years). At recruitment 15% of patients had diabetes, 75% chronic kidney disease (CKD), 65% experienced graft rejection. Mean ejection fraction (EF) was 55%. CAV was classified as type 2 in 28 cases and type 3 in 27 cases. Mean reference diameter (RD) was 2.79AE0.73 mm and mean lesion length 22.1AE13.7 mm. Overall 105 stents (two BMS, eight I generation DES, 67 II generation DES and 13 BRS were implanted. Average stented segment was 27.4AE18.6 mm long. Endovascular imaging was used in 24 cases All patients were treated with statins and 22 with everolimus.
