Background: Whereas transcatheter aortic valve implantation (TAVI) has become the gold standard for stenosis treatment in high-risk patients, it recently been extended to include intermediate risk patients. However, mortality rate at 5 years is still elevated. The aim of present study was develop a novel machine learning (ML) approach able identify best predictors 5-year after TAVI among severa...
Multidetector row computed tomographic (MDCT) assessment of aortic annulus dimensions and frame position and deployment have been associated with paravalvular aortic regurgitation (PAVR) after transcatheter aortic valve implantation (TAVI). The present evaluation investigated the (pre- and postprocedure) MDCT associates of PAVR ≥2+. In total, 123 patients referred for TAVI underwent clinical ev...
OBJECTIVES Transcatheter aortic valve implantation (TAVI) has become an established therapy for severe aortic stenosis (AS) in high-risk elderly individuals. Concomitant coronary artery disease (CAD) is frequently encountered in this patient population and may have an impact on outcomes. Hence, in patients with both severe AS and CAD, a bespoke therapy of both AS and/or CAD appears mandatory. ...
Introduction Left ventricular hypertrophy (LVH) is a common compensating process in the pressure overload mechanism of aortic stenosis (AS). Aim To identify a group of patients with a LVH pattern which may alter periprocedural and 1-year outcomes after transcatheter aortic valve implantation (TAVI). Material and methods Echocardiographic examinations of 226 patients with severe AS treated w...
BACKGROUND Transcatheter aortic valve implantation (TAVI) for high-risk and inoperable patients with severe aortic stenosis is an emerging procedure in cardiovascular medicine. Little is known of the impact of TAVI on renal function. METHODS We analysed retrospectively renal baseline characteristics and outcome in 58 patients including 2 patients on chronic haemodialysis undergoing TAVI at ou...
INTRODUCTION Aortic stenosis is the most prevalent type of valvular disease in Europe. Surgical aortic valve replacement (SAVR) is the standard therapy, while transcatheter aortic valve implantation (TAVI) is an alternative in patients at unacceptably high surgical risk. Assessment by a heart team is recommended by the guidelines but there is little published evidence on this subject. The purpo...
AIMS Conventional aortic valve replacement (AVR), sutureless AVR (su-AVR) and transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) are associated with conduction abnormalities. The aim of the present study was to assess the incidence of left bundle branch block (LBBB) after su-AVR and TAVI, in comparison to conventional AVR. METHODS AND RESULTS A total of 501 patient...
BACKGROUND Several studies have compared short-term and medium-term mortality rates for patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR), but no studies have compared short-term readmission rates for the 2 procedures. METHODS AND RESULTS New York's Cardiac Surgery Reporting System was used to propensity...
OBJECTIVES Surgical aortic valve replacement in patients with previous coronary artery bypass grafting (CABG) carries a high mortality. Transcatheter aortic valve implantation (TAVI) has been shown to be successful in high risk subgroups of patients. Our goal is therefore to evaluate the impact of a history of CABG on the outcome of patients who undergo TAVI. METHODS From October 2006 to June...
Objectives Transcatheter aortic valve implantation (TAVI) is an established treatment for patients with severe symptomatic aortic stenosis. It has a cerebrovascular accident rate of about 5% but the effect on retinal embolic events has not been previously reported. This study investigated the occurrence of retinal emboli following TAVI. Methods and analysis In this prospective observational s...
