Supports dobutamine echo-guided AVR decisions in AS with LV dysfunction; leaves open prospective RCT confirmation.
In patients with aortic stenosis and left ventricular dysfunction, dobutamine echocardiography is critical for assessing contractile reserve and guiding the timing of aortic valve replacement.
Asch et al. (2006) conducted a review in Aortic stenosis and left-ventricular dysfunction. Aortic valve replacement improves outcomes in patients with aortic stenosis and left-ventricular dysfunction, but management decisions should be tailored by dobutamine echocardiography results.
