Predictors of aortic stenosis severity reclassification using an imaging data fusion method in patients referred for transcatheter aortic valve implantation

Abstract

IDFM reclassified a substantial proportion of patients with severe AS into potentially moderate AS group and from low-flow to normal-flow AS group. Such regrouping calls for increased diagnostic prudence in AS patients, especially those with specific clinical and echocardiographic predictors of reclassification, such as DM or low AMG.

Assessment of the Willis circle flow changes and the severity of degenerative aortic stenosis and cognitive impairment

“…Symptoms of DAS (angina, dyspnea, syncope) often overlap with symptoms from the other common diseases, such as ischemic heart disease, anemia, hypertension, or cerebral ischemia [11][12][13][14]. While cardiac output gradually decreases, cerebral and peripheral flowvolume also putatively decrease, resulting in syncope, or cerebral hypoperfusion.…”

Association between calcification of mitro-aortic continuity and mitral regurgitation in patients undergoing transcatheter aortic valve replacement

“…Before TAVI all patients underwent routine laboratory testing, transthoracic echocardiocardiography (TTE), coronary angiography, MSCT as well as angio-MSCT of iliac and femoral arteries [17]. Aortic valve anatomy and diameter were evaluated by TTE and MSCT [18]. These studies were used for proper planning of the valve implantation in terms of selection of access route, valve size and complication risk assessment.…”
