This scientific statement highlights the need for guidance on managing acute decompensated heart failure in children, suggesting significant knowledge gaps.

“Published today, Evaluation and Management of the Child with Acute Decompensated Heart Failure: A Scientific Statement from the American Heart Association. A structured, rapid approach combining clinical assessment, diagnostics, and tailored therapy (medications, respiratory https://t.co/d684Q5aTc8”
Thanks to medical advances, we have more children living with heart disease and, therefore, more children coming into an emergency department or being hospitalized with heart failure. Research shows that once children get admitted for heart failure, they are much more likely than adults to need advanced cardiac therapies or die. And, while readmission rates have steadily declined in adults with heart failure — largely thanks to improved interventions and management practices — readmission rates have not changed for pediatric patients.
Does discontinuation of OAC after successful catheter ablation for atrial fibrillation safely prevent thromboembolic events compared to continued therapy?
Result: The incidence of thromboembolic events in patients who discontinued OAC after successful ablation remained low, though evaluation of net clinical benefit was limited by a low number of events.
Result: From baseline to 6 months, changes in KCCQ-OSS and 6MWD showed modest correlations with core lab-assessed LVEF (r=0.39; 95% CI: 0.16-0.58; p=0.0015 and r=0.39; 95% CI: 0.15-0.58; p=0.0022, respectively).
Does surgical mitral valve replacement in rheumatic heart disease patients yield similar one-year mortality compared to non-rheumatic heart disease patients and across different center volumes?
Result: One-year mortality did not differ significantly between RHD (6.4%) and non-RHD (13.8%) MVR patients (HR: 0.80; 95% CI 0.53-1.21; p=0.288).
Result: Summarizes 2025 advances in cardiovascular pharmacotherapy, including 4 new drug approvals (aficamten, etripamil, lerodalcibep, plozasiran), label expansions, major RCT results, and the withdrawal of Andexanet-alfa.
Does sacubitril/valsartan reduce hospitalization for heart failure, cardiovascular mortality, or all-cause mortality compared to enalapril in patients with HFrEF due to Chagas cardiomyopathy?
Result: No statistically significant differences between sacubitril/valsartan and enalapril in hospitalization for heart failure (RR = 0.93; 95% CI, 0.74–1.16; P = 0.53), cardiovascular mortality (RR = 0.91; 95% CI, 0.73–1.12; P = 0.37), or all-cause mortality (RR = 0.96; 95% CI, 0.79–1.17; P = 0.69).
Does once-weekly tirzepatide reduce cardiovascular events compared to dulaglutide in patients aged ≥40 years with type 2 diabetes mellitus and established ASCVD?
Result: The primary composite endpoint occurred in 12.2% of patients treated with tirzepatide and 13.1% of those treated with dulaglutide (HR 0.92, 95.3% CI: 0.83–1.01), meeting non-inferiority (P = 0.003) but not superiority (P = 0.09).
What are the mechanisms and consequences of vertical transmission of Group B Coxsackieviruses from mother to infant?
Result: Vertical transmission of CV-B can occur through transplacental passage or inhalation during delivery, leading to serious consequences including abortion, stillbirth, congenital malformations, and neonatal morbidity and mortality.

Result: Endocardial-epicardial LAPW asynchrony during persistent AF is characterized by greater epicardial compared with endocardial bipolar voltages, more frequent epicardial-to-endocardial activation gradients, and conduction block between surfaces.
Result: Round 1 showed 50% of items with I-CVIs <0.78 (S-CVI/AVE=0.77), prompting revisions, and final I-CVIs exceeded 0.78 for >95% of items.
