Do patients with asymptomatic aortic stenosis (AS) require surveillance with cardiac echocardiography? Evidence-based answer: Yes, because early surgery for asymptomatic patients with very severe AS results in higher actuarial and cardiac mortality-free survival (SOR: B, cohort trials). Transthoracic echocardiography is recommended for follow-up of asymptomatic patients annually for severe AS, every 1 to 2 years for moderate AS, and every 3 to 5 years for mild AS SOR: B, evidence-based guideline).
