Dobutamine stress echocardiography in patients with low-gradient aortic stenosis.
In adults with moderate or severe aortic stenosis (AS), valve replacement surgery is recommended when symptoms (ie, angina, syncope, or congestive heart failure) appear.1 In such patients, valve replacement surgery alleviates symptoms and improves survival, even in those with a depressed left ventricular ejection fraction (LVEF). Although a minority of patients with symptomatic AS have a reduce...
متن کاملDobutamine Stress Echocardiography Safety in Chagas Disease Patients
Background: A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially...
متن کاملPrognostic value of low-dose dobutamine stress echocardiography in patients with aortic stenosis and impaired left ventricular function
INTRODUCTION The aim of this multicenter, prospective study was to evaluate the long-term prognostic value of low-dose dobutamine stress echocardiography (LDDSE) in patients with aortic stenosis (AS) and depressed left ventricular (LV) function. MATERIAL AND METHODS The study group comprised 39 patients (34 male, mean age 59 ±13 years) with AS (peak gradient > 25 mm Hg), LV ejection fraction ...
متن کاملThe relation between transaortic pressure diVerence and flow during dobutamine stress echocardiography in patients with aortic stenosis
Objective—To investigate the relation between transaortic pressure diVerence and flow in patients with aortic stenosis. Methods—50 asymptomatic patients with all grades of aortic stenosis were studied using dobutamine stress echocardiography. Individual plots of mean pressure drop against flow were drawn. Comparisons were made between grades of aortic stenosis as defined by the continuity equat...
