Pediatric heart failure is a heterogeneous, high-risk clinical syndrome that differs fundamentally from adult heart failure in its etiologies, pathophysiology, and therapeutic responses. Although its absolute prevalence is lower, children experience disproportionate morbidity and mortality, with up to 40% of patients with symptomatic cardiomyopathy progressing to death or transplantation within 2 years of diagnosis. Congenital heart disease, cardiomyopathies, and genetic or metabolic disorders dominate the etiologic spectrum, while developmental differences in myocardial signaling, neurohormonal activation, and ventricular remodeling limit direct extrapolation of adult guideline-directed medical therapy. Evidence supporting pharmacologic treatment remains limited, and most therapies are symptom-modifying rather than outcome-modifying, particularly in single-ventricle physiology. Advances in mechanical circulatory support and heart transplantation have substantially improved survival, yet pose unique anatomic, physiological, and ethical challenges in children. This review synthesizes contemporary evidence across medical, device-based, and transplant therapies, highlights lesion- and age-specific considerations, and identifies critical research gaps needed to advance outcomes in pediatric heart failure.

Hypertension remains the leading modifiable risk factor for cardiovascular morbidity and mortality worldwide, yet blood pressure control rates remain suboptimal despite the availability of effective therapies. Contemporary guidelines increasingly recommend early use of combination therapy, recognizing that most patients require multiple agents to achieve target blood pressure. Widaplik, a recently Food and Drug Administration-approved fixed-dose, single-pill triple combination of telmisartan, amlodipine, and indapamide, represents the first triple therapy approved for initial treatment of hypertension in adults likely to need multidrug therapy. This review summarizes the pharmacologic rationale for low-dose triple therapy, highlighting complementary mechanisms targeting the renin-angiotensin-aldosterone system, vascular resistance, and sodium retention. We examine evidence from pivotal phase 3 trials demonstrating rapid, sustained blood pressure reductions, higher control rates compared with dual therapy, and favorable tolerability. We also discuss safety considerations, practical limitations, and gaps in evidence, including long-term cardiovascular outcomes. Widaplik represents a paradigm shift toward simplified, early combination therapy aimed at improving hypertension control and reducing cardiovascular risk.
