A limited, albeit clinically relevant, proportion of patients undergoing PCI-S has indication for OAC. Procedural management appears not substantially different from that of common patients. In-hospital major bleeding is relevant and should be taken into account when evaluating the overall hemorrhagic rate at a medium- to long-term follow-up.

Among the causes of in-hospital acute renal failure, contrast-induced nephropathy ranks third in prevalence. Although it represents a condition of renal impairment with spontaneous recovery, contrast nephropathy should always be considered, because it prolongs hospitalization and it may become a severe complication requiring dialysis. The purposes of this study are: (i) to determine if the application of the most effective contrast-induced nephropathy prevention strategies in the Cardiology Intensive Care Unit can prove to be successful in reducing nephropathy risk; and (ii) to identify which of the involved risk factors persist after the preventive treatment. We examined the patients who had a coronarography at the Bentivoglio hospital from April 2007 to April 2008 who required at least 3 days of permanence in hospital due to the presence of potential risk factors; 136 out of 784 patients were included. Among the selected patients, 21 (15.44%) developed a renal impairment compatible with contrast-induced nephropathy. The risk factors that seemed to display the best correlation with risk of contrast nephropathy were advanced age and an ventricular failure (ejection fraction <40%); however, the critical condition did not appear to be due to a single risk factor, but it resulted from the association of more contextual risk factors. Particularly, the concomitant presence of ventricular failure, anemia, diabetes, previous myocardial infarction and advanced age (>70 years) determined a threefold increased risk of contrast nephropathy. Our data suggest that the development of contrast nephropathy following coronarography is associated with worse renal function during hospitalization and at discharge.

Aims To evaluate the safety of a single and combined use of ultrasound-guided femoral puncture (U) and percutaneous arterial closure devices (P) in femoral artery procedures (FAP) compared to fluoroscopic guidance (F) and manual compression (M) in a large radial-focused interventional centre. U and P, taken individually, have improved safety in femoral arterial access procedures compared to traditional techniques. Methods and results All FAP performed between July 2017 and December 2018 in our centre were divided into three phases: (i) control period with F and M mainly performed; (ii) phase out period where U and P were introduced; and (iii) intervention period where a 6-month expertise on the novel techniques was acquired. The overall population was further stratified into subgroups: F/M, U/M, F/P, and U/P. The primary study endpoint was in-hospital access site bleeding events (BE) according to the BARC criteria. The secondary endpoint was vascular site complications (VASC). 418 procedures (14%) out of 3025 were performed via FA access during the study period. The overall access-site in-hospital BE were 97 (23%). Decreasing rates of BE (phase 1: n = 46, 29%; phase 2: n = 38, 22% e phase 3: n = 13, 15%; P = 0.027) and VASC were observed during the three periods. BE occurred significantly more often in F/M group (F/M: n = 48; 32%; U/M: n = 12, 16%; F/P: n = 18, 21%; U/P: n = 19, 17%; P = 0.008). F/M subgroup was an independent predictor of BE both in multivariable analysis and propensity score matching analysis. Conclusions The introduction of ultrasound-guided femoral puncture and percutaneous arterial closure devices has reduced access site bleeding with a progressive improvement after the first 6 months learning period.

Objective: To evaluate the safety of a single and combined use of ultrasound-guided femoral puncture (U) and percutaneous arterial closure devices (P) in femoral artery procedures (FAP) compared to fluoroscopic guidance (F) and manual compression (M) in a large radial-focused interventional centre.Background: U and P, taken individually, have improved safety in femoral arterial access procedures compared to traditional techniques.Methods: All FAP performed between July 2017 and December 2018 in our centre were divided into three phases: (a) control period with F and M mainly performed;(b) phase out period where U and P were introduced; (c) intervention period where a 6-month expertise on the novel techniques was acquired. The overall population was further stratified into subgroups: F/M, U/M, F/P, U/P. The primary study endpoint was in-hospital access site bleeding events (BE) according to the BARC criteria. The secondary endpoint was vascular site complications (VASC).Results: Four hundred eighteen procedures (14%) out of 3025 were performed via FA access during the study period. The overall access-site in-hospital BE were 97 (23%).Decreasing rates of BE (phase 1: n = 46, 29%; phase 2: n = 38, 22% e phase 3: n = 13, 15%; p = 0.027) and VASC were observed during the three periods.

F/M subgroup was an independent predictor of BE both in multivariable analysis and propensity score matching analysis. Conclusions:The introduction of ultrasound-guided femoral puncture and percutaneous arterial closure devices has reduced access site bleedings with a progressive improvement after the first 6 months learning period.
