Prosthetic heart valve (PHV) dysfunction is rare but potentially life-threatening. Although
often challenging, establishing the exact cause of PHV dysfunction is essential to determine …

Aims In view of the currently available evidence from randomized trials, we aimed to
compare the collective safety and efficacy of transcatheter aortic valve implantation (TAVI) …

Background Previous trials have shown that among high-risk patients with aortic stenosis,
survival rates are similar with transcatheter aortic-valve replacement (TAVR) and surgical …

Background The impact of aortic valve replacement (AVR) on progression/regression of
extravalvular cardiac damage and its association with subsequent prognosis is unknown …

Background: Prosthesis–patient mismatch (PPM) after surgical aortic valve replacement
(AVR) for aortic stenosis is generally associated with worse outcomes. Transcatheter AVR …

Background: Early experience with transcatheter aortic valve replacement (TAVR) within
failed bioprosthetic surgical aortic valves has shown that valve-in-valve (VIV) TAVR is a …

An important proportion of patients with aortic stenosis (AS) have a 'low-gradient'AS, ie a
small aortic valve area (AVA< 1.0 cm2) consistent with severe AS but a low mean …

Background: Few data exist on patients with low-flow, low-gradient aortic stenosis (LFLG-
AS) undergoing transcatheter aortic valve replacement (TAVR). Also, very scarce data exist …

Background It remains controversial whether prosthesis-patient mismatch (PPM)(in general
considered moderate if indexed effective orifice area is 0.65-0.85 cm2/m2 and severe …

Background The study investigators previously reported that moderate aortic stenosis (AS) is
associated with a poor prognosis in patients with heart failure (HF) with reduced left …
