The transradial approach is the main route in France to perform percutaneous coronary intervention, reaching nearly 60% of the cases in 2008. Its proven benefit in reducing bleeding complications and therefore its impact on morbidity and mortality are now well documented. However, a definite learning curve is necessary in relation with specifics challenges. Radial spasm and anatomical variations are the main reasons to explain failures encountered during its implementation. In order to increase success procedure, these difficulties and the ways to overcome them must be well-known. Finally, success rate is now comparable to the classical femoral approach.

Aspirin versus Clopidogrel monotherapy beyond 1 month after complex percutaneous coronary intervention: A pre-specified subgroup analysis of the STOPDAPT-3 trial.
Eur Heart J Cardiovasc Pharmacother
January 2025
Department of Cardiology, Hirakata Kohsai Hospital, Hirakata, Japan.
Aims: There were no previous studies comparing aspirin versus P2Y12 inhibitor monotherapy following short dual antiplatelet therapy (DAPT) after complex percutaneous coronary intervention (PCI).
Methods And Results: We conducted a prespecified subgroup analysis based on complex PCI in the 1-year results of the STOPDAPT-3 trial, which randomly compared 1-month DAPT followed by aspirin monotherapy (aspirin group) to 1-month prasugrel monotherapy followed by clopidogrel monotherapy (clopidogrel group). The main analysis in the present study was the 30-day landmark analysis.
A Multivariate Analysis of a Modified Frailty Index on Perioperative Morbidity and Mortality Following Non-Emergent Endovascular Aortic Aneurysm Repair.

Division of Vascular Surgery, University of South Florida College of Medicine, Tampa, Florida, USA. Electronic address:
Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).

Section of Interventional Cardiology, MedStar Washington Hospital Center, Washington, DC, USA. Electronic address:
Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.
Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).
Rationale and Design of the Prevail Global Trial Program Evaluating the Prevail Drug-Coated Balloon in Patients with In-stent Restenosis and De Novo Small Vessel Disease.
Am Heart J
January 2025
Clinical and Experimental Interventional Cardiology, University of Saarland, Homburg, Germany.
Background And Rationale: In-stent restenosis (ISR) remains the leading cause of treatment failure following percutaneous coronary intervention (PCI) with contemporary drug-eluting stents. Especially in small caliber coronary arteries, restenosis is common following PCI and represents a treatment challenge. Drug-coated balloons (DCB) are an attractive alternative to stents for treatment of both ISR and small vessel disease.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.
