High-Output Mechanical Circulatory Support in Left Main Interventions: The Magenta Elevate High-Risk PCI First-in-Human Study.

Background: The Magenta Elevate is a 9-F, self-expanding, catheter-mounted pump delivered sheathed through a commercially available 10-F femoral introducer over the wire to the left ventricle (LV), providing temporary hemodynamic support up to an equivalent of normal cardiac output.

Objectives: The authors sought to assess the feasibility and outcomes of Elevate-supported high-risk percutaneous coronary intervention (HR-PCI) in a first-in-human study and study the hemodynamic impact of high-output support during prolonged interventional left main coronary artery (LM) occlusions.

Methods: In this study, 14 patients underwent Elevate-supported HR-PCI, with 8 patients undergoing 20 prolonged (39 ± 16 seconds) balloon occlusions of an unprotected LM.

Covered Stent Correction for Sinus Venosus Atrial Septal Defects, an Emerging Alternative to Surgical Repair: Results of an International Registry.

Background: Covered stent correction for a sinus venosus atrial septal defect (SVASD) was first performed in 2009. This innovative approach was initially viewed as experimental and was reserved for highly selected patients with unusual anatomic variants. In 2016, increasing numbers of procedures began to be performed, and in several centers, it is now offered as a standard of care option alongside surgical repair.

Long-term safety and efficacy of endovascular ultrasound renal denervation in resistant hypertension: 8-year results from the ACHIEVE study.

Background: Ultrasound renal sympathetic denervation (uRDN) reduces blood pressure (BP) in the absence and presence of antihypertensive treatment at 2 months. Beyond 3 years, there is a lack of follow-up data. This study investigated the long-term safety and efficacy of uRDN.

TRIVALVE Score: A Risk Score for Mortality/Hospitalization Prediction in Patients Undergoing Transcatheter Tricuspid Valve Intervention.

Background: Transcatheter tricuspid valve intervention (TTVI) has been increasingly adopted in recent years for the treatment of patients with tricuspid regurgitation (TR). However, no dedicated risk stratification has been established for patients undergoing TTVI.

Objectives: The aim of the present study was to propose a dedicated risk score for patients affected by severe TR undergoing TTVI.

Percutaneous LAAO and Pulsed-Field Isolation in a Canine Model: Feasibility and Safety Evaluation.

In this study, we investigated the feasibility, safety, and efficiency of using a novel device system to perform percutaneous left atrial appendage occlusion concomitant with left atrial appendage electrical isolation (LAAEI) via pulsed field ablation. In the acute phase, LAAEI was successful in 10 of 10 canines. At follow-up, full endothelialization was observed in 5 of 5 (100%) cases at 6 months.

A multi-center study of the MicroNET-covered stent in consecutive patients with acute carotid-related stroke: SAFEGUARD-STROKE.

Introduction: Acute carotid-related stroke (CRS), with its large thrombo-embolic load and large volume of affected brain tissue, poses significant management challenges. First generation (single-layer) carotid stents fail to insulate the athero-thrombotic material; thus they are often non-optimized (increasing thrombosis risk), yet their use is associated with a significant (20-30%) risk of new cerebral embolism.

Aim: To evaluate, in a multi-center multi-specialty investigator-initiated study, outcomes of the MicroNET-covered (cell area ≈ 0.

Effects of tricuspid transcatheter edge-to-edge repair on tricuspid annulus diameter - Data from the TriValve registry.

Aims: T-TEER is an effective therapy for the treatment of tricuspid regurgitation (TR). However, the effects of leaflets clipping on tricuspid valve annulus (TA) have not been investigated in detail. The aim of this study is to investigate the effects of tricuspid transcatheter edge-to-edge repair (T-TEER) on TA diameter.

Endovascular Baroreflex Amplification With the MobiusHD Device in Patients With Heart Failure and Reduced Ejection Fraction: Interim Analysis of the First-in-Human Results.

Background: Endovascular baroreflex amplification with the MobiusHD, a self-expanding stent-like device that is implanted in the internal carotid artery, was designed to reduce the sympathetic overactivity that contributes to progressive heart failure with reduced ejection fraction.

Methods: Symptomatic patients (New York Heart Association class III) with heart failure with reduced ejection fraction (left ventricular ejection fraction [LVEF] ≤40%) despite guideline directed medical therapy and n-terminal pro-B type natriuretic peptide (NT-proBNP) levels ≥400 pg/mL in whom carotid ultrasound and computed tomographic angiography demonstrated absence of carotid plaque were enrolled. Baseline and follow-up measures included 6-minute walk distance (6MWD), Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ OSS), and repeat biomarkers and transthoracic echocardiography.

Transcatheter Aortic Valve Replacement Outcomes in End-Stage Renal Disease Patients on Hemodialysis Requiring Midodrine.

Background: Patients with dialysis-dependent end-stage renal disease (ESRD) taking midodrine may be at high risk for poor outcomes following transcatheter aortic valve replacement (TAVR). We evaluated dialysis-dependent ESRD patients taking midodrine.

Methods: We conducted a retrospective analysis of non-clinical trial TAVR patients from February 2012 to December 2020 from 11 facilities in a Western US health system.

Challenges and Burdens in the Coronary Artery Disease Care Pathway for Patients Undergoing Percutaneous Coronary Intervention: A Contemporary Narrative Review.

Clinical and economic burdens exist within the coronary artery disease (CAD) care pathway despite advances in diagnosis and treatment and the increasing utilization of percutaneous coronary intervention (PCI). However, research presenting a comprehensive assessment of the challenges across this pathway is scarce. This contemporary review identifies relevant studies related to inefficiencies in the diagnosis, treatment, and management of CAD, including clinician, patient, and economic burdens.

Safety, usability, and performance of a wireless left atrial pressure monitoring system in patients with heart failure: the VECTOR-HF trial.

Aims: In heart failure (HF), implantable haemodynamic monitoring devices have been shown to optimize therapy, anticipating clinical decompensation and preventing hospitalization. Direct left-sided haemodynamic sensors offer theoretical benefits beyond pulmonary artery pressure monitoring systems. We evaluated the safety, usability, and performance of a novel left atrial pressure (LAP) monitoring system in HF patients.
