Asymptomatic Aortic Stenosis
During the past 2 decades, the dynamic nature of valvular heart disease has become a recognized phenomenon. Changes in loading conditions, heart rate, and ventricular contractility that occur with exercise can alter the physiological effects of valvular disease. Disparity between resting evaluation of valve dysfunction and patient symptoms is not uncommon. Stress echocardiography (SE) has emerg...
متن کاملExercise echocardiography in severe asymptomatic aortic stenosis.
The management of asymptomatic patients with severe aortic stenosis is challenging. Unfortunately, evaluation of symptoms such as dyspnoea remains subjective. The use of exercise echocardiography may help to predict major events in patients with asymptomatic severe aortic stenosis. This article explains how to perform the test and discusses which echocardiographic measurements should be obtaine...
متن کاملClinical Outcome in Asymptomatic Severe Aortic Stenosis
Methods Transthoracic echocardiography and measurement of B-type natriuretic peptide level from venous blood sample were performed in 150 consecutive patients with asymptomatic severe AS and normal exercise test. Patients were classified in 4 groups, depending on left ventricular flow state (normal flow [NF] vs. low flow [LF]: 35 ml/m) and pressure gradient levels (low gradient [LG] vs. high gr...
متن کاملStress Testing in Asymptomatic Aortic Stenosis.
Aortic stenosis is 1 of the most common heart valve diseases among adults. When symptoms develop, prognosis is poor, and current guidelines recommend prompt aortic valve replacement. Depending of the severity of the aortic stenosis and the presence of concomitant heart disease and medical comorbidities, stress testing represents a reasonable strategy to help better risk stratify asymptomatic pa...
متن کاملManagement of Asymptomatic Severe Aortic Stenosis
Patients with symptomatic severe aortic stenosis (AS) benefit from aortic valve replacement surgery, but the management of patients with asymptomatic severe AS is more controversial. While cholesterol and angiotensin have been linked to AS progression, we should await the results of ongoing randomized trials before medical therapy to lower cholesterol or inhibit angiotensin can be recommended t...
