Current and Future Treatment Landscape of Transthyretin Amyloid Cardiomyopathy.

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive disease caused by the deposition of insoluble amyloid fibrils derived from misfolded transthyretin (TTR). The treatment landscape is rapidly evolving, with disease-modifying therapies now targeting distinct steps in disease progression. Management requires both disease-modifying treatment and symptom-guided treatment of heart failure and arrhythmias, along with device therapy and consideration of advanced heart failure interventions (i.e., heart transplantation) in select patients. Therapeutic advances have significantly increased treatment possibilities, selection of appropriate therapy, switching between therapies, combination strategies, and how to monitor treatment response over time. This review summarizes available and investigational therapies for ATTR-CM and considers practical questions that guide clinical decision-making, with the goal of helping clinicians navigate the evolving therapeutic landscape.
