Prevalence and Prognostic Significance of Restriction Versus Systolic Dysfunction in Patients With Transthyretin and Light Chain Cardiac Amyloidosis

This large retrospective study of 820 patients reveals that restrictive ventricular physiology is the most common phenotype in cardiac amyloidosis. While preserved LV function offers better initial survival, the rate of progression to restriction is high, emphasizing the need for early clinical detection.

Cardiovascular Risk Scores Overestimate Mortality in Mexican Adults: The Urgent Need for Population-Specific Recalibration

A prospective study of over 112,000 adults in Mexico City reveals that standard CVD risk scores consistently overestimate 10-year fatal risk. Recalibration of the Globorisk-fatal model significantly improves predictive accuracy, highlighting the need for population-specific tools in clinical practice.

Refining ARVC Risk Stratification: Does Left Ventricular Late Gadolinium Enhancement Add Incremental Value to Clinical Risk Calculators?

A multi-center study of 385 ARVC patients reveals that while Left Ventricular Late Gadolinium Enhancement (LV LGE) correlates with ventricular arrhythmias, it fails to provide incremental prognostic value beyond the established ARVC risk calculator, reinforcing the calculator's role as the primary tool for clinical decision-making.

Superior Long-Term Hemodynamics with Self-Expanding Valves in Small Failed Bioprostheses: 3-Year Insights from the LYTEN Trial

The 3-year analysis of the LYTEN trial reveals that self-expanding valves (SEV) significantly outperform balloon-expandable valves (BEV) in hemodynamic metrics for valve-in-valve TAVR in patients with small surgical bioprostheses, although clinical outcomes and quality of life improvements remain comparable.
