Discontinuation of Beta-Blocker Therapy after Myocardial Infarction
Evidence suggests that beta-blocker discontinuation was noninferior to continuation in stable post-MI adults without heart failure or reduced ejection fraction. Signal observed in this randomized trial of 2,540 patients that discontinuation group had comparable outcomes (7.2% vs 9.0% 4-year event rate) for the composite endpoint of death, MI, or heart failure hospitalization. Worth noting this provides mechanistic insights for carvedilol use, though the adult post-MI population differs from pediatric heart failure contexts.

Frequency and Outcomes of Acute Hemodynamic Instability Following Transcatheter Tricuspid Valve Replacement
Signal observed that acute hemodynamic instability occurred in 8.5% of transcatheter tricuspid valve replacement patients, with 35.2% intrahospital mortality versus 0.1% in stable patients. Evidence suggests that elevated pulmonary capillary wedge pressure, reduced left ventricular ejection fraction, and impaired renal function were significant risk factors. Worth noting these hemodynamic principles may inform understanding of valve interventions in complex congenital heart disease.
Elevated left-sided filling pressures, pulmonary hypertension, and impaired renal function are associated with an increased risk for AHI, suggesting that patient selection and preprocedural optimization...

Outcomes and predictors of atrial fibrillation in cardiac amyloidosis
Evidence suggests atrial fibrillation was present in 47% of cardiac amyloidosis patients, with notably higher prevalence in wild-type ATTR-CA (80%) compared to AL-CA (33%). Signal observed that AF patients had more severe heart failure symptoms and reduced left ventricular ejection fraction (47% vs 53%). Worth noting the high anticoagulation rate (78%) with low stroke incidence (6% over 12 months) in this population.
Prospective, randomized studies are essential to establish optimal AF treatment protocols in this population.

Management and Outcome of Failed Transcatheter Tricuspid Edge-to-Edge Repair
Signal observed that device-related failure after tricuspid transcatheter edge-to-edge repair occurred in 5.4% of 2,278 procedures, with 73% associated with severe or greater residual tricuspid regurgitation. Evidence suggests reintervention achieved greater TR reduction and right atrial reverse remodeling compared to medical therapy, though composite outcomes remained similar (38.2% death or heart failure rehospitalization). Worth noting these tricuspid valve intervention outcomes may inform understanding of right-sided valve disease management in complex congenital contexts.
Reintervention achieves greater TR reduction and right atrial reverse remodeling than medical therapy, but events remain similar between both strategies.
Relevance: Adult tricuspid intervention study with outcomes relevant to understanding valve disease management in single ventricle/Fontan populations where tricuspid regurgitation is important

Incidence, Clinical Implications, and Predictors of Paravalvular Leak Following Transcatheter Tricuspid Valve Replacement
Evidence suggests moderate or severe paravalvular leak occurred in 6.1% of transcatheter tricuspid valve replacement patients and was associated with increased 1-year mortality (39.7% vs 10.5-12.6% in those with less significant leak). Signal observed that larger right atrial volume, device malposition, and type IV valve morphology independently predicted moderate or severe paravalvular leak. Worth noting these findings on right-sided valve replacement outcomes may inform management strategies in complex congenital heart disease.

Safety Profile of SGLT-2 Inhibitors in Older Adults
Evidence suggests SGLT2 inhibitors were associated with reduced risks of acute renal failure (OR 0.86), mortality (OR 0.84), and serious adverse events (OR 0.84) but increased genital infections (OR 3.32) and volume depletion (OR 1.18) in older adults. Signal observed that genital infection risk escalated sharply with age (≥75 years OR 9.29) and exhibited dose-response relationship. Worth noting these emerging heart failure therapies show favorable benefit-risk profiles in older populations with heart failure.
This study provides actionable insights for personalized therapy in geriatric care.

Quantifying skeletal muscle energy metabolism during exercise in heart failure with preserved ejection fraction
Signal observed that patients with heart failure and preserved ejection fraction had prolonged phosphocreatine recovery halftime compared to controls (27 vs 24 seconds) using 31P magnetic resonance spectroscopy during exercise. Evidence suggests impaired whole-muscle oxidative capacity was independent of iron deficiency status, with high-sensitive C-reactive protein associated with prolonged recovery times. Worth noting these mechanistic insights into exercise intolerance in heart failure may inform understanding of exercise physiology in pediatric heart failure populations.
