Patient Preferences in Pulmonary Arterial Hypertension, a Latent Class Analysis to Identify Preference Heterogeneity.

Objectives: Pulmonary arterial hypertension (PAH) is a chronic, progressive disease of the pulmonary circulation characterized by vascular remodeling that, if untreated, can lead to right heart dysfunction and death. This analysis measured heterogeneity in patient preferences for PAH-specific treatment regimens.

Method: Adult patients with PAH with slight to marked limitations during physical activity were recruited through a patient organization in Germany.

Predictors of outcomes in mild pulmonary hypertension according to 2022 ESC/ERS Guidelines: the EVIDENCE-PAH UK study.

Background And Aims: Interventional studies in pulmonary arterial hypertension completed to date have shown to be effective in symptomatic patients with significantly elevated mean pulmonary artery pressure (mPAP) (≥25 mmHg) and pulmonary vascular resistance (PVR) > 3 Wood Unit (WU). However, in health the mPAP does not exceed 20 mmHg and PVR is 2 WU or lower, at rest. The ESC/ERS guidelines have recently been updated to reflect this.

An Update on Drug-eluting Technology in Peripheral Arteries to Treat Peripheral Arterial Disease.

For the treatment of peripheral arterial disease, drug-eluting technology is a widely accepted therapeutic option, with significant reduction in intimal hyperplasia and, consequently, use of target lesion revascularization. Nevertheless, the reputation of such devices was damaged after a meta-analysis, published in December 2018, showed increased mortality in patients receiving paclitaxel-eluting devices. Although subsequent studies have failed to establish such correlation, the use of paclitaxel-eluting devices remains heavily restricted.

Influence of vessel morphology and variations on technical and clinical success in mechanical thrombectomy: -In vivo and in vitro analyses.

Purpose: To determine the impact of vessel variation and anatomical features on technical and clinical success.

Materials And Methods: In vitro blood clots (n=100) were introduced into a silicon carotid-T flow model of 2, 3 or 4mm. The ICA/M1angle varied at 45°, 90°, 135° and 180°.

Initial clinical experience with the micromesh Roadsaver carotid artery stent for the treatment of patients with symptomatic carotid artery disease.

Purpose: To assess the effectiveness, technical aspects, handling, and safety of the micromesh Roadsaver Carotid Artery Stent in the treatment of atherosclerotic carotid artery stenosis and tandem lesions in ischemic stroke patients.

Methods: Seven patients (5 men; mean age 75±11.4 years, range 53-86) suffering from symptomatic internal carotid artery (ICA) stenosis (mean 76% diameter reduction) were treated with the dual layer closed-cell stent without embolic protection.

Lesion-Related Carotid Angioplasty and Stenting with Closed-Cell Design without Embolic Protection Devices in High-Risk Elderly Patients-Can This Concept Work Out? A Single Center Experience Focusing on Stent Design.

To compare the performance differences of three carotid artery stents in high-risk elderly patients without embolic protection devices (EPDs) on the basis of stent design, procedure-related complications, conveniences in handling, in-stent restenosis, 30-day outcome, and long-term follow-up. A total of 101 symptomatic internal carotid stenoses of 94 patients were prospectively treated with stent-protected angioplasty to 94 patients. Three closed-cell stents, one of those being hybrid cell design, were chosen depending on vascular anatomy: curved vessel, lesion length > 1 cm: 64 Carotid Wallstent (Boston Scientific, Natick, MA); curved vessel, lesion length < 1 cm: 21 Cristallo Ideale (Invatec, Roncadelle, Italy); straight vessel, lesion length > 1 cm: 16 Xact (Vascular Abbott, Santa Clara, CA).
