Aortic Stenosis (AS) is present in approximately 2% of people and is most commonly caused by degenerative calcification of the aortic valve. Without aortic valve intervention, aortic stenosis is associated with substantial morbidity and mortality in patients, particularly in those presenting with angina, syncope, or heart failure. The current gold standard for treatment of Aortic Stenosis is su...
Heyde's syndrome is the association between calcific aortic stenosis and gastrointestinal bleeding due to angiodysplasia. Alterations in von Willebrand factor due to turbulence across the diseased aortic valve have been incriminated in the pathophysiology of this syndrome. Replacement of the aortic valve has been reported to stop the bleeding, but this is debatable. Along with a review of the r...
Background Degenerative aortic stenosis (AS) and wild type transthyretin (TTR)-related cardiac amyloidosis (wt-ATTR) share a common demographic and clinical profile. It has been recently suggested that the coexistence of wt-ATTR could negatively influence the outcome of elderly patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). TTR-related cardiac amyloidosi...
Aortic stenosis (AS) is a narrowing of the aortic valve opening that restricts normal blood flow to the entire body. It is estimated to be prevalent in up to 7% of the population over the age of 65 [1]. It is also more likely to affect men than women as 80% of adults with symptomatic aortic stenosis are male [1]. After the onset of symptoms, patients with severe aortic stenosis have a survival ...
A 73-year-old woman was admitted to our hospital for a scheduled percutaneous transcatheter balloon valvuloplasty of a stenotic tricuspid bioprosthesis. The patient had a history consistent with exertional dyspnea, abdominal distension, and edema of the lower extremities resistant to diuretic treatment over the previous few months. Forty-three years prior, she underwent aortic valve replacement...
In the aortic stenosis group, the left ventricular (LV) muscle mass index was a good parameter for predicting the prognosis. Associated mitral valve disease had no influence on long term survival after aortic valve replacement. In the aortic insufficiency group, associated mitral valve disease had a marked influence on the results of aortic valve replacement. In general, the aortic insufficienc...
Criteria for selection of patients with aortic valve disease for cardiac catheterization are described, based on a study of 81 cases. Children with aortic stenosis warrant catheterization at the time when the clinical diagnosis is made, but in adults this examination may be deferred until symptoms appear or left ventricular hypertrophy is recognized. In patients with pure aortic insufficiency c...
Echocardiography was used to study left ventricular size and contraction in 128 patients with isolated aortic valve disease -45 patients with aortic stenosis, 25 with mixed aortic valve disease and 58 with aortic regurgitation. Left ventricular measurements included the end-diastolic internal dimension (LVIDd), mural thickness (PWTd), an index of circumferential myocardial contraction-fractiona...
AIMS To examine how left atrioventricular plane displacement (AVPD), a widely used measure of left ventricular (LV) function, is related to presence and degree of aortic stenosis. METHODS AND RESULTS Cardiac dimensions, LV filling, left AVPD, LV ejection fraction (LVEF), and valve function were assessed by echocardiography/Doppler in 182 patients with various cardiac diseases (mean (SD) age 6...
OBJECTIVE To determine the relative importance of the different causes of isolated aortic valve stenosis in a surgical series, and to relate these to patient characteristics including the rate of insertion of bypass grafts for coronary artery disease. DESIGN Survey of the clinical and pathological data on patients undergoing aortic valve replacement for isolated stenosis. SETTING Tertiary c...
