Key result
Phenotype-based approach linking echo and hemodynamics guides individualized vasoactive and mechanical support in severe AS.
Why the study?
Vasoactive strategies specific to aortic stenosis-related cardiogenic shock remain limited in guideline statements, reflecting an absence of disease-specific evidence and the need for a physiology-driven framework prior to definitive valve intervention.
Proposes a physiology-driven, phenotype-based framework to guide individualized vasoactive and mechanical circulatory support management in patients with severe aortic stenosis and cardiogenic shock prior to definitive valve intervention.
May inform vasoactive and support decisions in severe AS shock; leaves open prospective validation before practice change.
The management of cardiogenic shock in patients with severe aortic stenosis is particularly challenging given that standard resuscitation can worsen hemodynamics in the setting of fixed outflow obstruction, hypertrophic myocardium, and tenuous coronary perfusion pressure. Pharmacologic therapy or mechanical circulatory support are therefore bridges to definitive valve intervention, not destinations. However, vasoactive strategies specific to aortic stenosis-related cardiogenic shock remain limited in guideline statements, reflecting the absence of disease-specific evidence and the need for a physiology-driven framework to guide management prior to definitive valve intervention. We review a phenotype-based approach that links echocardiographic flow-gradient state, Society for Cardiovascular Angiography and Interventions shock stage, and clinical or invasive hemodynamics to individualized selection of vasopressors, inotropes, afterload reduction, and mechanical circulatory support under intensive monitoring.

Oro et al. (2026) conducted a review in Cardiogenic shock in severe aortic stenosis. Phenotype-based approach to vasoactive management was evaluated. A phenotype-based approach linking echocardiographic state, shock stage, and hemodynamics guides individualized selection of vasoactive therapies and mechanical support in severe aortic stenosis.
