Impact of Access Site on Periprocedural Bleeding and Cerebral and Coronary Events in High-Bleeding-Risk Percutaneous Coronary Intervention: Findings from the RIVA-PCI Trial.

Introduction: The preference for using transradial access (TRA) over transfemoral access (TFA) in patients requiring percutaneous coronary intervention (PCI) is based on evidence suggesting that TRA is associated with less bleeding and fewer vascular complications, shorter hospital stays, improved quality of life, and a potential beneficial effect on mortality. We have limited study data comparing the two access routes in a patient population with atrial fibrillation (AF) undergoing PCI, who have a particular increased risk of bleeding, while AF itself is associated with an increased risk of thromboembolism.

Methods: Using data from the RIVA-PCI registry, which includes patients with AF undergoing PCI, we analyzed a high-bleeding-risk (HBR) cohort.

Rivaroxaban in Patients With Atrial Fibrillation Who Underwent Percutaneous Coronary Intervention in Clinical Practice.

Little is known about the efficacy and safety of rivaroxaban in patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI) in clinical practice. We therefore conducted a prospective observational study to determine the rate of ischemic, embolic, and bleeding events in patients with AF and PCI treated with rivaroxaban in a real-world experience. The RIVA-PCI ("rivaroxaban in patients with AF who underwent PCI") (clinicaltrials.

Current status of antithrombotic therapy and in-hospital outcomes in patients with atrial fibrillation undergoing percutaneous coronary intervention in Germany.

Background: Little is known about current patterns of antithrombotic therapy in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) in clinical practice in Germany.

Methods: The RIVA-PCI is a prospective, non-interventional, multicenter study with follow-up until hospital discharge including consecutive patients with AF undergoing PCI.

Results: Between January 2018 and March 2020, 1636 patients (elective in 52.

Polymer-free sirolimus-eluting stents in a large-scale all-comers population.

Objective: The objective of this study was to assess the safety and efficacy of a polymer-free sirolimus coated, ultrathin strut drug-eluting stent (PF-SES) in an unselected patient population with a focus on acute coronary syndrome (ACS). Furthermore, stable coronary artery disease (CAD) with short (≤6 months) versus long (>6 months) dual antiplatelet therapy (DAPT) were also studied.

Methods: Patients who received PF-SES were investigated in an unselected large-scale international, single-armed, multicenter, 'all comers' observational study.

PP049. The arterio-venous ratio of retinal vessels in the first trimester as a predictor for preeclampsia.

Introduction: Retinal changes are known in severe preeclampsia (PE). This is the first study evaluating static retinal vessel analysis in pregnancy to measure retinal vessel diameter and in women destined to develop preeclampsia.

Methods: 51 non-pregnant controls (29±4 years) and 601 pregnant women (30±6 years) arterio-venous ratio (AVR) of retinal arterioles and venules was measured with Dynamic Vessel Analyzer in 1.

Measurements and mapping of 282,420 nerve fibers in the S1-5 nerve roots.

Object: The study aims to analyze nerve fiber types in the sacral nerve roots as a prerequisite for stimulation.

Methods: One-micrometer cross-sections of human ventral and dorsal S1-5 roots were stained with osmium and toluidine blue. The total fiber diameter and myelin sheath were measured in 282,420 nerve fibers.

Constrictive pericarditis, still a diagnostic challenge: comprehensive review of clinical management.

The diagnosis of constrictive pericarditis (CP) continues to be a challenge in the modern era. Understanding the pathophysiology and integrating the results of invasive and non-invasive techniques are important in the differential diagnosis of CP and e.g.
