Purpose of review: Stress echocardiography is recommended in valvular heart disease when there is a mismatch between resting transthoracic echocardiography findings and symptoms during activities of daily living. We describe the current methodology and the evidence supporting these applications. Recent findings: The comprehensive stress echo assessment includes valve function (gradients and regurgitation), left ventricular global systolic and diastolic function, left atrial volume, pulmonary congestion, pulmonary arterial pressure, and right ventricular function, integrated with blood pressure response with cuff sphygmomanometer, chronotropic reserve with heart rate, and symptoms. Recent guidelines recommend the evaluation of asymptomatic severe or symptomatic non-severe mitral regurgitation or stenosis with exercise stress and suspected low-flow, low-gradient severe aortic stenosis with reduced ejection fraction with low dose (up to 20 mcg, without atropine) dobutamine stress. Prospective, large-scale studies based on a comprehensive protocol (ABCDE +) capturing the multiplicity of clinical phenotypes are needed to support stress echo-driven treatment strategies.

Abstract
Purpose of review: Stress echocardiography is recommended in valvular heart disease when there is a mismatch between resting transthoracic echocardiography findings and symptoms during activities of daily living. We describe the current methodology and the evidence supporting these applications. Recent findings: The comprehensive stress echo assessment includes valve function (gradients and regurgitation), left ventricular global systolic and diastolic function, left atrial volume, pulmonary congestion, pulmonary arterial pressure, and right ventricular function, integrated with blood pressure response with cuff sphygmomanometer, chronotropic reserve with heart rate, and symptoms. Recent guidelines recommend the evaluation of asymptomatic severe or symptomatic non-severe mitral regurgitation or stenosis with exercise stress and suspected low-flow, low-gradient severe aortic stenosis with reduced ejection fraction with low dose (up to 20 mcg, without atropine) dobutamine stress. Prospective, large-scale studies based on a comprehensive protocol (ABCDE +) capturing the multiplicity of clinical phenotypes are needed to support stress echo-driven treatment strategies.File | Dimensione | Formato | |
