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.

Carotid endarterectomy or stenting or best medical treatment alone for moderate-to-severe asymptomatic carotid artery stenosis: 5-year results of a multicentre, randomised controlled trial.

Background: The optimal treatment for patients with asymptomatic carotid artery stenosis is under debate. Since best medical treatment (BMT) has improved over time, the benefit of carotid endarterectomy (CEA) or carotid artery stenting (CAS) is unclear. Randomised data comparing the effect of CEA and CAS versus BMT alone are absent.

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.

Survey of clinical practice pattern in Germany's certified chest pain units : Adherence to the European Society of Cardiology guidelines on non-ST-segment elevation acute coronary syndrome.

Background: We aimed to analyze the 2020 standard of care in certified German chest pain units (CPU) with a special focus on non-ST-segment elevation acute coronary syndrome (NSTE-ACS) through a voluntary survey obtained from all certified units, using a prespecified questionnaire.

Methods: The assessment included the collection of information on diagnostic protocols, risk assessment, management and treatment strategies in suspected NSTE-ACS, the timing of invasive therapy in non-ST-segment elevation myocardial infarction (NSTEMI), and the choice of antiplatelet therapy.

Results: The response rate was 75%.

Anticoagulation versus antiplatelet therapy after percutaneous left atrial appendage closure-subanalysis from the multicenter LAARGE registry.

Purpose: Data regarding post-procedural antithrombotic therapy following percutaneous left atrial appendage (LAA) in real-world populations using various occluder systems is limited. In the present analysis, anticoagulation (AC) was compared against antiplatelet therapy (APT) using data from the real-world multi-center LAARGE study.

Methods: Patients following LAA closure enrolled in the LAARGE study were assigned to two groups depending on initial post-implantation antithrombotic regime consisting of either AC or APT.

Successful implementation of best medical treatment for patients with asymptomatic carotid artery stenosis within a randomized controlled trial (SPACE-2).

Background: Asymptomatic carotid artery stenosis (ACS) can be treated with carotid endarterectomy (CEA), carotid artery stenting (CAS), or best medical treatment (BMT) only. For all treatment options, optimization of vascular risk factors such as arterial hypertension, hyperlipidemia, smoking, obesity, and insufficient physical activity is essential. Data on adherence to BMT and lifestyle modification in patients with ACS are sparse.

Contralateral Stenosis and Echolucent Plaque Morphology are Associated with Elevated Stroke Risk in Patients Treated with Asymptomatic Carotid Artery Stenosis within a Controlled Clinical Trial (SPACE-2).

Background: Asymptomatic carotid artery stenosis (ACS) has a low risk of stroke. To achieve an advantage over noninterventional best medical treatment (BMT), carotid endarterectomy (CEA) or carotid artery stenting (CAS) must be performed with the lowest possible risk of stroke. Therefore, an analysis of risk-elevating factors is essential.

Ultrasonography Grading of Internal Carotid Artery Disease: Multiparametric German Society of Ultrasound in Medicine (DEGUM) versus Society of Radiologists in Ultrasound (SRU) Consensus Criteria.

Purpose:  We sought to determine the diagnostic agreement between the revised ultrasonography approach by the German Society of Ultrasound in Medicine (DEGUM) and the established Society of Radiologists in Ultrasound (SRU) consensus criteria for the grading of carotid artery disease.

Materials And Methods:  Post-hoc analysis of a prospective multicenter study, in which patients underwent ultrasonography and digital subtraction angiography (DSA) of carotid arteries for validation of the DEGUM approach. According to DEGUM and SRU ultrasonography criteria, carotid arteries were independently categorized into clinically relevant NASCET strata (normal, mild [1-49 %], moderate [50-69 %], severe [70-99 %], occlusion).

Management of Pulmonary Embolism: Results from the German Chest Pain Unit Registry.

Introduction: Since 2008, specialized chest pain units (CPUs) were implemented across Germany ensuring structured diagnostics in acute chest pain. This study aims to analyze the management of pulmonary embolism (PE) patients in such certified CPUs.

Methods: Data were retrieved from 13,902 patients enrolled in the German CPU registry and analyzed for the diagnosis of PE including patient characteristics, critical time intervals, diagnostic workup, treatment, and prognosis.

WATCHMAN versus ACP or Amulet devices for left atrial appendage occlusion: a sub-analysis of the multicentre LAARGE registry.

Aims: Several left atrial appendage (LAA) closure systems are available. Due to differences in device design, the results of specific occluders derived from trials cannot simply be generalised to all devices. The present analysis sought to assess two contemporary LAA closure devices in clinical practice.

Long-term transesophageal echocardiography follow-up after percutaneous left atrial appendage closure.

Background: Peri-device leaks and device thrombi are assumed to lead to ischemic events after percutaneous left atrial appendage occlusion (LAAO). While these device-related complications are well assessed until 12 months after LAAO, no data are available beyond this period.

Objective: The purpose of this study was to assess device-related complications beyond 12 months after LAAO.

Interventional occlusion of left atrial appendage in patients with atrial fibrillation. Acute and long-term outcome of occluder implantation in the LAARGE Registry.

Background: Left atrial appendage occluder (LAAO) implantation is an alternative method for stroke prevention in atrial fibrillation (AF) patients who are not eligible for long-term oral anticoagulation. The present paper describes the acute and 1-year follow-up outcome data of the prospective, multicenter German left atrial appendage occlusion registry (LAARGE).

Methods: LAARGE enrolled 641 patients who were scheduled for LAAO implantation.

Interdisciplinary consensus on indications for transfemoral transcatheter aortic valve implantation (TF-TAVI) : Joint Consensus Document of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte e.V. (ALKK) and cooperating Cardiac Surgery Departments.

Indications for TF-TAVI (transfemoral transcatheter aortic valve implantation) are rapidly changing according to increasing evidence from randomized controlled trials. Present trials document the non-inferiority or even superiority of TF-TAVI in intermediate-risk patients (STS-Score 4-8%) as well as in low-risk patients (STS-Score < 4%). However, risk scores exhibit limitations and, as a single criterion, are unable to establish an appropriate indication of TF-TAVI vs transapical TAVI vs SAVR (surgical aortic valve replacement).

Effect of renal insufficiency and diabetes mellitus on in-hospital mortality after acute coronary syndromes treated with primary PCI. Results from the ALKK PCI Registry.

Background: It is known that patients with acute coronary syndromes (ACS) and diabetes mellitus (DM) are at higher risk for in-hospital adverse events. However, we hypothesized that the higher event rate is due to the patients' subgroup with renal failure (RF), a common sequel of DM.

Methods And Results: We used data of the prospective ALKK-PCI registry including all consecutive percutaneous coronary interventions (PCI) for ACS of 48 hospitals between 2008 and 2013.

Angioplasty in asymptomatic carotid artery stenosis vs. endarterectomy compared to best medical treatment: One-year interim results of SPACE-2.

Background: Treatment of individuals with asymptomatic carotid artery stenosis is still handled controversially. Recommendations for treatment of asymptomatic carotid stenosis with carotid endarterectomy (CEA) are based on trials having recruited patients more than 15 years ago. Registry data indicate that advances in best medical treatment (BMT) may lead to a markedly decreasing risk of stroke in asymptomatic carotid stenosis.

Immediate unselected coronary angiography versus delayed triage in survivors of out-of-hospital cardiac arrest without ST-segment elevation: Design and rationale of the TOMAHAWK trial.

Patients experiencing out-of-hospital cardiac arrest (OHCA) without ST-segment elevation are a heterogenic group with a variety of underlying causes. Up to one-third of patients display a significant coronary lesion compatible with myocardial infarction as OHCA trigger. There are no randomized data on patient selection and timing of invasive coronary angiography after admission.

The German CPU registry: Comparison of smokers and nonsmokers.

Background: Chest pain is a major reason for admission to an internal emergency department, and smoking is a well-known risk factor for coronary artery disease (CAD) and acute coronary syndrome (ACS). The aim of this analysis is to illustrate the differences between smokers and nonsmokers presenting to German chest pain units (CPU) in regard to patient characteristics, CAD manifestation, treatment strategy, and prognosis.

Methods: From December 2008 to March 2014, 13,902 patients who had a complete 3‑month follow-up were enrolled in the German CPU registry.

Validation of Multiparametric Ultrasonography Criteria with Digital Subtraction Angiography in Carotid Artery Disease: A Prospective Multicenter Study.

Purpose:  The German Society of Ultrasound in Medicine (DEGUM) recently revised its multiparametric criteria for duplex ultrasonography (DUS) grading of internal carotid artery (ICA) disease. We determined the diagnostic accuracy of the revised DEGUM criteria for ultrasonography grading of ICA disease in a prospective multicenter study.

Materials And Methods:  We evaluated consecutive patients who underwent digital subtraction angiography of the extracranial carotid arteries at four tertiary care hospitals.

Guideline-adherence regarding critical time intervals in the German Chest Pain Unit registry.

Background: Since 2008, the German Cardiac Society certified 256 Chest Pain Units (CPUs). Little is known about adherence to recommended performance measures in patients with suspected acute coronary syndrome (ACS) presenting to CPUs. We investigated guideline-adherence regarding critical time intervals and selected performance measures in German Chest Pain Units.
