OBJECTIVES The aim of this study was to determine the relationship between aortic valve morphology and valve dysfunction. BACKGROUND The morphology of the bicuspid or bicommissural aortic valve (BAV) may predict the severity of valve dysfunction. Therefore, we assessed the relationship between BAV, aortic coarctation, and the degree of valve pathology in children. METHODS A retrospective re...
Real-time, cross-sectional echocardiograms were recorded in 28 consecutive adult patients with valvular aortic stenosis using a high resolution, mechanical sector scanner. Using the cross-sectional technique, the aortic valve orifice diameter was recorded in each of the 28 patients. With M-mode echocardiographic examination of these same patients, this value could be estimated in only 21 of the...
To examine factors that might affect progression in valvular aortic stenosis (AS), we reviewed serial hemodynamic studies in 50 adult patients. Seven patients had congenital, 22 rheumatic and 21 degenerative-calcific aortic stenosis. The patients with calcific aortic stenosis were older (62 ± 6 vs 51 ± 9 years, p < 0.001) and had onset of murmur later in life. For all patients average values at...
We report on a very rare case of left ventricular aneurysm in a 77-year-old patient with aortic valve stenosis and without coronary artery disease. The patient underwent conventional aortic valve replacement and left ventricular aneurysmectomy with an uneventful postoperative course. The cause of the left ventricular aneurysm was suspected to be a long history of aortic valve stenosis that led ...
in Aortic Stenosis " 1 with great interest and would like to commend the authors for producing novel coronary wave intensity data in the aortic stenosis population. The microcirculatory decompression (suction) wave was reported to increase in proportion to the severity of aortic stenosis (rϭ0.59, Pϭ0.05), a change opposite to that which was reported previously by the same authors in patients wi...

This report describes 30 patients under the age of 30 years with rheumatic aortic stenosis, presenting with combined aortic and mitral stenosis. Three patients had additional tricuspid stenosis. Twenty-eight patients gave a history of rheumatic polyarthritis. The diagnosis was confirmed by right and left heart catheterisation in all. The murmur of aortic stenosis was not initially present in 8 ...
A bicuspid aortic valve is the most common cause of isolated valvular aortic stenosis in the pediatric age group; another cause is annular hypoplasia, with the tricuspid valve being the least commonly involved. In aortic stenosis, causes of systolic dysfunction are critical stenosis, secondary fibroelastosis and noncompaction. Critical stenosis is diagnosed in the usual fashion. Secondary fibro...
Surgical replacement of the aortic valve is the standard therapy for severe aortic valve stenosis. However, it is generally associated with increased mortality and morbidities in older individuals. Transcatheter aortic valve implantation (TAVI) is a less invasive procedure and has shown similar clinical outcomes as surgical treatment in elderly patients at high risk for conventional surgery. In...
as the population ages, aortic valve stenosis becomes more prevalent. Patients who are symptomatic due to aortic valve stenosis have a severely diminished life expectancy and are, therefore, candidates for surgical aortic valve replacement.1 That said, many of these patients (estimated up to one-third) do not undergo surgery, mainly because of the presence of severe comorbidities and the associ...
