Impaired Atrial and Ventricular Strain Predicts Heart Failure in Arrhythmogenic Right Ventricular Cardiomyopathy.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) increases the risk of heart failure (HF) and arrhythmias. Speckle-tracking echocardiography (STE) detects myocardial dysfunction, but its predictive role for HF in this population remains unclear.

Methods: Seventy-one patients with ARVC (age 43.

Neoaortic Regurgitation Detected by Echocardiography After Arterial Switch Operation: A Systematic Review and Meta-Analysis.

Background: Neoaortic root dilatation (NeoARD) and neoaortic regurgitation (NeoAR) are common sequelae following the arterial switch operation (ASO) for transposition of the great arteries.

Objectives: The authors aimed to estimate the cumulative incidence of NeoAR, assess whether larger neoaortic root dimensions were associated with NeoAR, and evaluate factors associated with the development of NeoAR during long-term follow-up.

Methods: Electronic databases were systematically searched for articles that assessed NeoAR and NeoARD after ASO, published before November 2022.

Sacubitril-valsartan vs ACE/ARB in pediatric heart failure: A retrospective cohort study.

Background: The first angiotensin receptor/neprilysin inhibitor on the market, sacubitril-valsartan, has shown marked improvements in death and hospitalization for heart failure among adults, and is now approved for use in pediatric heart failure. While the ongoing PANORAMA-HF trial is evaluating the effectiveness of sacubitril-valsartan for pediatric patients with a failing systemic left ventricle, the enrollment criteria do not include the majority of pediatric heart failure patients. Additional studies are needed.

Impact of prolonged ischemic time on pediatric heart transplantation outcomes: Improved outcomes in the most recent era.

Background: Impacts of ischemic time (IT) on pediatric heart transplant outcomes are multifactorial. We aimed to analyze the effect of prolonged IT on graft loss after pediatric heart transplantation. We hypothesized that graft survival with prolonged IT has improved across eras.

Recommendations for centers performing pediatric heart surgery in the United States.

Care and outcomes for the more than 40,000 patients undergoing pediatric and congenital heart surgery in the United States annually are known to vary widely. While consensus recommendations have been published across numerous fields as one mechanism to promote a high level of care delivery across centers, it has been more than two decades since the last pediatric heart surgery recommendations were published in the United States. More recent guidance is lacking, and collaborative efforts involving the many disciplines engaged in caring for these children have not been undertaken to date.
