The present trial will give important information on what is the best anticoagulation regimen when performing PCI through the femoral approach in patients at high risk for bleeding.

AKI in CKD patients undergoing CAS is mostly due to hemodynamic depression and is associated with a higher 30-day major adverse events rate.

High loading dose of rosuvastatin within 24 hr before elective PCI seems to decrease the incidence of periprocedural myocardial necrosis during a period of 12-months compared to the standard treatment.

Subintimal tracking and re-entry (STAR) technique has been described as a bailout strategy for coronary total occlusion (CTO) recanalization. However, the length of the dissected segment represents a major concern. The aim of this study is, to evaluate whether "deferred" stent implantation may limit the total stent length following STAR recanalization of CTO. All consecutive patients with CTO in a native coronary artery treated by successful STAR technique in our institution were included. In the first period (March 2004-December 2009) all procedures were completed with stent implantation (Elective Stent Group; n = 60). Thereafter (January 2010-June 2012) stent implantation was postponed until a scheduled (within 3 months) angiographic follow-up (Deferred Stent Group; n = 69). The dissection length was 75 ± 37 mm in the Elective Stent Group and 83 ± 31 mm in the Deferred Stent Group (P = 0.22). In the Deferred Stent Group, at the angiographic follow-up, the dissection length was significantly shorter than at the index procedure (40 ± 35 mm versus 83 ± 31 mm, P <0.001). The total stent length was significantly shorter in the Deferred Stent Group versus the Elective Stent Group (22 ± 33 mm versus 56 ± 28 mm; P < 0.001). At six-month follow-up, rate of cardiac death and myocardial infarction (6.7% vs 0; P = 0.049) and of stent thrombosis (5% vs 0%; P = 0.10) were higher in the Elective Stent Group. The present study suggests that deferring stenting implantation following STAR recanalization (1) limits the stent length and (2) is associated with a lower rate of objective endpoints.

RenalGuard therapy is safe and effective in reaching high UFR. Mean intraprocedural UFR ≥450 mL/h should be the target for optimal CI-AKI prevention.

The results of this randomized study, carried out at a single institution, suggest that there is no difference in major bleeding rate between bivalirudin and UFH in increased-risk patients undergoing transfemoral PCI. (Novel Approaches in Preventing and Limiting Events III Trial: Bivalirudin in High-Risk Bleeding Patients [NAPLES III]; NCT01465503).

This non-randomised pilot study suggests that RenalGuard Therapy may be effective in preventing AKI in CKD patients undergoing TAVI.
