Can Grading of Mild Cardiac Allograft Vasculopathy be Further Refined? An angiographic and physiologic assessment of heart transplant recipients with ISHLT CAV 1.

Background: Cardiac allograft vasculopathy (CAV) results in impaired blood flow in both epicardial vessels and the microvasculature and is a leading cause of poor outcomes in heart transplant (HT) recipients. Most patients have mild (ISHLT CAV 1) disease. This study examined outcomes amongst those with ISHLT CAV 1 and investigated the value of physiologic assessment via cardiac positron emission tomography/computed tomography (PET/CT) for added risk stratification.

Aortic Valve Replacement vs Clinical Surveillance in Asymptomatic Severe Aortic Stenosis: A Systematic Review and Meta-Analysis.

Background: Current guidelines recommend a strategy of clinical surveillance (CS) for patients with asymptomatic severe aortic stenosis (AS) and a normal left ventricular ejection fraction.

Objectives: The aim of this study was to conduct a study-level meta-analysis of randomized controlled trials (RCTs) evaluating the effect of early aortic valve replacement (AVR) compared with CS in patients with asymptomatic severe AS.

Methods: Studies were quantitatively assessed in a meta-analysis using random-effects modeling.

Transcatheter Tricuspid Valve Replacement.

Transcatheter tricuspid valve replacement (TTVR) has emerged as a promising intervention for the treatment of severe tricuspid regurgitation with complex valve morphology. This consensus document provides a comprehensive overview of the current state of orthotopic TTVR, focusing on patient selection, procedural details, and follow-up care. Clinical outcomes from initial studies and compassionate use cases are discussed, highlighting the effectiveness of TTVR in reducing tricuspid regurgitation, inducing reverse right ventricular remodeling, and enhancing patients' quality of life.

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.

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.

Design and rationale of the evaluation of transcatheter aortic valve replacement compared to surveillance for patients with asymptomatic severe aortic stenosis: The EARLY TAVR trial.

Background: For patients with asymptomatic, severe aortic stenosis (AS) and preserved left ventricular ejection fraction, current guidelines recommend clinical surveillance every 6 to 12 months. To date, no randomized trials have examined whether an early intervention with transcatheter aortic valve replacement (TAVR) will improve outcomes among these patients.

Study Design And Objectives: EARLY TAVR is a prospective, randomized, controlled, and multicenter trial, with an event-based design.

The Mortality Burden of Untreated Aortic Stenosis.

Background: The American College of Cardiology/American Heart Association guidelines recommend the assessment and grading of severity of aortic stenosis (AS) as mild, moderate, or severe, per echocardiogram, and recommend aortic valve replacement (AVR) when the AS is severe.

Objectives: The authors sought to describe mortality rates across the entire spectrum of untreated AS from a contemporary, large, real-world database.

Methods: We analyzed a deidentified real-world data set including 1,669,536 echocardiographic reports (1,085,850 patients) from 24 U.

Kynurenine pathway metabolism evolves with development of preclinical and scleroderma-associated pulmonary arterial hypertension.

Understanding metabolic evolution underlying pulmonary arterial hypertension (PAH) development may clarify pathobiology and reveal disease-specific biomarkers. Patients with systemic sclerosis (SSc) are regularly surveilled for PAH, presenting an opportunity to examine metabolic change as disease develops in an at-risk cohort. We performed mass spectrometry-based metabolomics on longitudinal serum samples collected before and near SSc-PAH diagnosis, compared with time-matched SSc subjects without PAH, in a SSc surveillance cohort.

Correlating state-specific and national trends in breast reconstruction after Medicaid expansion: A decade-long update on the Affordable Care Act's impact.

While disparities in access to reconstruction persist, a comprehensive analysis comparing state-based outcomes and national patterns in breast reconstruction as a result of Medicaid expansion has never been examined. In this study, we investigated how breast reconstruction rates changed as a result of Medicaid expansion and compared these state-based findings to national counterparts. Patient data from the Healthcare Cost and Utilization Project among states that chose to expand Medicaid were compared with those from states that did not expand.

Radioprotection for the imaging specialist during structural heart interventions: Not an option!

Structural heart interventions are steadily increasing, and the majority requires echocardiographic guidance. As a result, imaging specialists are exposed to the harmful effects of scattered ionizing radiation. This X-ray exposure must be quantified, its potential consequences should be monitored by occupational medicine and the "as low as reasonably achievable" principles of radioprotection should be optimized (including increasing the distance, decreasing the duration, using shielding radiation and providing safety training for the imaging specialist).

Rationale and design of a randomized study comparing the Watchman FLX device to DOACs in patients with atrial fibrillation.

Background: Percutaneous left atrial appendage (LAA) closure (LAAC) was developed as a nonpharmacologic alternative to oral anticoagulants (OACs) in patients with atrial fibrillation (AF) who are at an increased risk for stroke or systemic embolism. The Watchman device permanently seals off the LAA to prevent thrombi from escaping into the circulation. Previous randomized trials have established the safety and efficacy of LAAC compared to warfarin.

Impact of Eruptive vs Noneruptive Calcified Nodule Morphology on Acute and Long-Term Outcomes After Stenting.

Background: Whether an eruptive or noneruptive target lesion calcified nodule (CN) portends worse acute and long-term clinical outcomes after stenting has not been established.

Objectives: The authors sought to compare acute and long-term clinical outcomes in eruptive CN vs noneruptive CN morphology.

Methods: Using optical coherence tomography, an eruptive CN was defined as an accumulation of small calcium fragments protruding and disrupting the overlying fibrous cap, typically with small amount of thrombus.

Multimodality Imaging of Right Heart Function: JACC Scientific Statement.

Right ventricular (RV) size and function assessed by multimodality imaging are associated with outcomes in a variety of cardiovascular diseases. Understanding RV anatomy and physiology is essential in appreciating the strengths and weaknesses of current imaging methods and gives these measurements greater context. The adaptation of the right ventricle to different types and severity of stress, particularly over time, is specific to the cardiovascular disease process.

Patient-Level Pooled Analysis of Ultrasound Renal Denervation in the Sham-Controlled RADIANCE II, RADIANCE-HTN SOLO, and RADIANCE-HTN TRIO Trials.

Importance: Ultrasound renal denervation (uRDN) was shown to lower blood pressure (BP) in patients with uncontrolled hypertension (HTN). Establishing the magnitude and consistency of the uRDN effect across the HTN spectrum is clinically important.

Objective: To characterize the effectiveness and safety of uRDN vs a sham procedure from individual patient-level pooled data across uRDN trials including either patients with mild to moderate HTN on a background of no medications or with HTN resistant to standardized triple-combination therapy.
