Update on left ventricular outflow tract obstruction.

Abstract

The diagnosis and management of left ventricular outflow tract obstruction have evolved substantially since its initial characterization by invasive cardiac catheterization nearly 70 years ago. This review traces the historical progression of our understanding of left ventricular outflow tract obstruction, with a particular focus on the pivotal role of echocardiography in redefining its detection, hemodynamic assessment, and clinical relevance, especially as its prevalence is expected to increase along with the growing aging population.
