Relaxin mimetic in pulmonary hypertension associated with left heart disease: Design and rationale of Re-PHIRE.

Aims: Despite receiving guideline-directed medical heart failure (HF) therapy, patients with pulmonary hypertension associated with left heart disease (PH-LHD) experience higher mortality and hospitalization rates than the general HF population. AZD3427 is a functionally selective, long-acting mimetic of relaxin, a hormone that has the potential to induce vasodilation and prevent fibrosis. In a phase 1b study conducted in patients with HF, AZD3427 demonstrated a favourable safety and pharmacokinetic profile.

Formulation of Quality Improvement Methodology for Risk Mitigation in Congenital Cardiac Catheterization.

The C3PO collaborative, with a history of successful quality improvement (QI) initiatives, leveraged registry participants to develop a multi-center QI initiative to reduce adverse events (AEs) in congenital cardiac catheterization. A 32-person, interdisciplinary working group analyzed audited data for all congenital cardiac catheterization cases from 2014-2017. The primary outcome was the occurrence of any high-severity (level 3/4/5) AE.

Rescuing the Right Ventricle: Mechanical Support After Pediatric Heart Transplantation.

Background: Right ventricular (RV) failure after heart transplantation (HT) is common in those with pretransplantation elevated pulmonary vascular resistance (PVR). Mechanical circulatory support has been used as a bridge to recovery, with mixed outcomes. We describe a patient with failed single-ventricle palliation in whom severe RV failure developed after HT.

Automated stenosis estimation of coronary angiographies using end-to-end learning.

The initial evaluation of stenosis during coronary angiography is typically performed by visual assessment. Visual assessment has limited accuracy compared to fractional flow reserve and quantitative coronary angiography, which are more time-consuming and costly. Applying deep learning might yield a faster and more accurate stenosis assessment.

Adolescent transition preparation around the COVID-19 pandemic: A cross-sectional study.

Objective: To compare preparation for transition in adolescents in the United States prior to and during the COVID-19 pandemic.

Study Design: We used data from the 2019 and 2021 National Survey of Children's Health to compare transition preparation before and after the COVID-19 pandemic among adolescents who had a medical care visit within the preceding year, controlled for relevant potential confounders. The association of demographic factors and survey year with a composite measure of adequate transition preparation was evaluated using univariable analysis and multivariable logistic regression.

Transurethral resection of the prostate (TUR-P) and associated risk of infective endocarditis.

Purpose: Bacteremia is a well-known complication to surgery and may result in infective endocarditis (IE). Transurethral resection of the prostate (TUR-P) may give rise to bacteremia, but the associated risk of IE is not well described. We aimed to examine risk of infective endocarditis following TUR-P.

Characteristics, outcomes and the necessity of continued guideline-directed medical therapy in patients with heart failure with improved ejection fraction.

Background: Much remains to be learned about patients with heart failure with improved ejection fraction (HFimpEF).

Objective: This study sheds light on the characteristics and clinical outcomes of HFimpEF patients, including the consequences of halting guideline-directed medical therapy (GDMT).

Methods: This retrospective study was conducted on patients diagnosed with heart failure with reduced ejection fraction (HFrEF) who underwent a second echocardiogram at least 6 months apart between January 2009 and February 2023.

Challenges in the Development and Evaluation of Pediatric Heart Valve Technologies.

Background: In October 2022, the Heart Valve Collaboratory and Food and Drug Administration convened a global multidisciplinary workshop to address the unmet clinical need to promote and accelerate the development of pediatric-specific heart valve technologies.

Methods: The Pediatric Heart Valve Global Multidisciplinary Workshop was convened in October 2022. Key stakeholders, including expert clinicians in pediatric cardiology and cardiac surgery, valve manufacturers, engineers and scientists were assembled to review the current state-of-the-art, discuss unique challenges in the pre-and post-market evaluation of pediatric valve therapies, and highlight emerging technologies that show potential to address some of the key unmet needs of children with valve disease.

Global, Regional, and National Burden of Valvular Heart Disease, 1990 to 2021.

Background: Valvular heart disease poses an escalating global health challenge with an increasing impact on mortality and disability. This study aims to comprehensively analyze the global burden of valvular heart disease.

Methods And Results: Using the Global Burden of Disease 2021 data, we analyzed the prevalence and disability-adjusted life years, examining implications across demographics and geographic regions.

Atrial and ventricular functional mitral regurgitation: prevalence, characteristics, outcomes, and disease progression.

Aims: Limited data exist on the natural history of functional mitral regurgitation (FMR), including atrial (AFMR), ventricular (VFMR), and dual FMR. This study examined the prevalence, characteristics, outcomes, and progression of these FMR subtypes.

Methods And Results: Consecutive patients with ≥mild to moderate FMR were included and classified as AFMR, VFMR, or dual FMR.

Equity and center variation in listing status exceptions for pediatric heart transplant candidates since pediatric review board implementation.

Background: A pediatric national heart review board (NHRB) and exception guidance document to standardize decision-making were implemented in 2021 to reduce variability and ensure equity in status exceptions for pediatric candidates. We evaluated the hypothesis that these changes decreased center variability and racial disparities within the granted exceptions.

Methods: Guidance document and pediatric NHRB were operational by February and June 2021, respectively.
