Severe aortic stenosis and myocardial function: diagnostic and prognostic usefulness of ultrasonic integrated backscatter analysis.
BACKGROUND The aim of this study was to assess the myocardial reflectivity pattern in severe aortic valve stenosis through the use of integrated backscatter (IBS) analysis. Patients with aortic stenosis (AS) were carefully selected in the Department of Cardiology. METHODS AND RESULTS Thirty-five subjects (AS: valve orifice < or =1 cm2; 12 female; mean age, 71.8+/-6.2 years) and 25 healthy sub...
متن کاملSignificance of myocardial fibrosis on cardiac function and morphology in severe aortic stenosis
Methods Eighty-nine patients (53 male, mean age 60 years) with pure severe AS (n = 36) or severe AS with mild aortic regurgitation (n = 53) were included in the study. All patients underwent transthoracic echocardiography (TTE), cardiac computed tomography (CCT) and cardiac magnetic resonance (CMR) and subsequent valvuloplasty operation. Patients were analyzed according to the presence and abse...

he physical forces that impede myocardial shortening afterload) are highly relevant to pharmacologic, mechanial, and surgical treatments for left ventricular systolic ysfunction. The maintenance of a normal or near-normal fterload, matched appropriately to robust myocardial conractility and accompanied by adequate venous return and eart rate, together ensure the teleologic cardiac function of e...
متن کاملMyocardial extracellular volume fraction and myocardial fibrosis by cmr in patients with severe aortic stenosis
Background Severe aortic stenosis (AS) induces diffuse interstitial myocardial fibrosis (MF). CMR late gadolinium enhancement (LGE) technique is useful to detect focal MF. The amount of MF is associated with worse long-term prognosis after aortic valve replacement surgery (AVR). Measurements of T1 relaxation times before and after gadolinium administration allow determination of myocardial extr...
متن کاملSevere aortic stenosis: forgotten associations.
The authors present the case of a 68-year-old man with predominantly right heart failure in the context of severe aortic stenosis associated with pulmonary hypertension. Anemia was diagnosed which, after endoscopic study, was considered to be secondary to angiodysplasia and a diagnosis of Heyde syndrome was made. After valve replacement surgery the patient's heart failure improved and hemoglobi...
