Tracking progression of aortic stenosis with echocardiography.

ABSTRACT:

Background

Transthoracic echocardiography (TTE) is used to assess aortic stenosis (AS) severity and track disease progression. As the field moves to study medical therapies to halt disease progression, reliable non-invasive imaging markers that are sensitive to small changes in disease progression are needed to enable efficient trial designs. The signal-to-noise ratio of commonly obtained TTE-based measures of progressive (non-severe) AS severity is unknown.

Methods

This is a retrospective study of TTEs done at a tertiary referral centre (Tufts Medical Center, Boston MA). A cohort of patients with progressive AS who had two TTEs done within 30 days (in the absence of valve intervention) and a cohort of progressive AS patients with TTEs ≥ 1 year apart, also without valvular i
