...Hyungseop Kim; In-Cheol Kim; Hee-Jeong Lee Introduction: The definition of low-flow/low-gradient aortic stenosis (AS) using the stroke volume index (SVI) alone overlooks factors like vascular resistance and valve stiffness. Consequently, an SVI indicating a normal flow might indicate a low flow...

...Daanyaal Wasim; Abukar Mohamed Ali; Øyvind Bleie; Kjetil H. Løland; Ronak Rajani; Svein Rotevatn; Sahrai Saeed Introduction: Left ventricular (LV) remodelling and fibrosis are known to occur in patients with aortic stenosis (AS) and are linked to post-intervention outcomes. These myocardial changes...

...) aortic stenosis (AS) due to shear force-induced proteolysis. The prognostic value of HMW VWF multimer deficiency is unknown. Therefore, we sought to evaluate the impact of HMW VWF multimer deficiency on clinical outcome. Methods: In this prospective research study, a total of 83 patients with classical...

... for systolic dysfunction other than LVEF (left ventricular ejection fraction) and provides additional prognostic information. Method: Search literature published between 2010 and 2023 on relevant platforms and contain the following keywords: “Aortic valve disease,” “Aortic stenosis,” “Aortic regurgitation...

... to the worse baseline characteristics instead of the urgent nature of the procedure. Severe aortic stenosis (AS) is the most frequent valvular disease in developed countries [ 1‒3 ], being associated with bad prognosis if left untreated (mortality rates of approximately 50% in the first 2 years...

... of sex on outcomes following aortic valve replacement (AVR) for aortic stenosis (AS) in the era of routine TAVR. Methods: We performed a cross-sectional analysis of the National Inpatient Sample (2009–18) to study AS visits for all AVR and in-hospital outcomes as a function of sex. Survey estimation...

... ]. Unicuspid aortic valve Echocardiography Aortic stenosis Unicuspid aortic valve (UAV) is a rare congenital malformation that was first reported by Edwards in 1958 [1]. UAV has been categorized into 2 subtypes: acommissural UAV and unicommissural UAV. UAV is associated with severe aortic stenosis...

... results on haemodynamic performance and mortality rates. However, the impact of these bioprostheses on left ventricular mass (LVM) regression remains unknown. We decided to study the changes in remodelling and LVM regression in isolated severe aortic stenosis treated with conventional or Perceval®...

... undergoing transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) are less known. Methods: We enrolled 150 symptomatic patients (mean age 82 ± 8 years, 58% female, and pre-TAVI aortic valve area 0.40 ± 0.19 cm/m 2 ) with severe AS who underwent 2D transthoracic echocardiography and 2D...

...Ankur Sethi; Vamsi Kodumuri; Vinoy Prasad; Ashok Chaudhary; James Coromilas; John Kassotis Background: Mitral regurgitation (MR) is commonly encountered in patients with severe aortic stenosis (AS). However, its independent impact on mortality in patients undergoing transcatheter aortic valve...

...Jonathan Weber; Simcha Pollack; Florentina Petillo; Ana Anagnostopoulos; J. Jane Cao; Eddy Barasch Background: Aortic valve weight (AVW), a flow independent measure of aortic stenosis (AS) severity, is reported to have heterogeneous associations with the echocardiographic variables used...

...; Amparo Martínez Monzonís; José Luis Zamorano Gómez; SITAR (Strain Imaging in Transcatheter Aortic-Valve Replacement) group Purpose: Left ventricular (LV) mechanics are impaired in patients with severe aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has become a widespread technique...

...Dragos Alexandru; Simcha Pollack; Florentina Petillo; J. Jane Cao; Eddy Barasch Objectives: To substitute the stroke volume index (SVi) with flow rate (FR) in the hemodynamic classification of severe aortic stenosis (AS) with preserved ejection fraction (EF), in order to evaluate its prognostic...

... outcomes following transcatheter aortic valve implantation (TAVI) in general and specifically in patients with high-gradient aortic stenosis (AS). Methods: We reviewed 317 consecutive patients who underwent TAVI at our institution. We investigated the relation between AVG as a continuous/categorical...
