BACKGROUND/AIM Electrophysiological changes are observed following mechanical stretches due to pressure overload in patients with severe aortic stenosis (AS). The electrical instability occurs after depolarization and dispersion of repolarization. The aim of this study was to evaluate changes in ventricular repolarization following transcatheter aortic valve implantation (TAVI). MATERIALS AND...

INTRODUCTION Few studies have assessed the development of transcatheter aortic valve implantation (TAVI) in Poland since its introduction in 2008, and data on current TAVI activity or practice are missing. AIM To assess the dynamics of TAVI adoption in Poland and to detect differences among Polish centres in TAVI practice and decision-making. MATERIAL AND METHODS The Polish Interventional C...

AIMS This study analysed the impact of transapical (TA) vs. transfemoral (TF) access site transcatheter aortic valve implantation (TAVI) on post-procedural regional left ventricular (LV) function using cardiac magnetic resonance (CMR) feature tracking (FT). METHODS AND RESULTS CMR was performed 3 months after TAVI on 44 consecutive patients with normal LV ejection fraction prior to TAVI. Twen...

OBJECTIVES This study sought to evaluate the impact of new conduction defects after transcatheter aortic valve implantation (TAVI) on the evolution of left ventricular (LV) function during 1-year follow-up. BACKGROUND New left bundle branch block (LBBB) or need for permanent pacing due to atrioventricular (AV) block are frequent after TAVI. METHODS A total of 90 consecutive patients treated...

PURPOSE We sought to evaluate the clinical usefulness of decision making by a multidisciplinary heart team for identifying potential candidates for transcatheter aortic valve implantation (TAVI) in patients with symptomatic severe aortic stenosis. MATERIALS AND METHODS The multidisciplinary team consisted of two interventional cardiologists, two cardiovascular surgeons, one cardiac imaging sp...

BACKGROUND Transcatheter aortic valve implantation (TAVI) has been an alternative to conventional aortic valve replacement (AVR) in old and high risk patients. The goal of this study is to compare the early outcomes of conventional AVR vs. TAVI in high risk severe AS patients. METHODS From January 2008 to July 2012, 44 high risk severe aortic stenosis patients underwent conventional AVR, and ...

Transcatheter aortic valve insertion (TAVI) has taken center stage, but TAVI is not easy to do, has limitations, and is a complex procedure requiring multiple operators. Thus, interventional cardiologists, cardiac surgeons, echocardiographers, anesthesiologists, and vascular surgeons have formed “teams” that come together to work in hybrid operating rooms or catheterization laboratories to perf...

OBJECTIVES To describe short-term clinical and echocardiography outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). To explore patient selection criteria for treatment with TAVI. DESIGN TAVI patients (n = 45) were matched to SAVR patients (n = 45) with respect to age within ± 10 years, sex and systolic left ventricular f...

Transcatheter aortic valve implantation (TAVI) represents a real revolution in the field of interventional cardiology for the treatment of elderly or high-risk surgical patients with severe symptomatic aortic valve stenosis. Today, TAVI seems to play a key and a reliable role in the treatment of intermediate and maybe low-risk patients with severe aortic stenosis. TAVI has also evolved from a c...

OBJECTIVES The first transcatheter aortic valve implantation (TAVI) in England and Wales was performed in 2007. This study presents the subsequent national activity and outcomes for both TAVI and aortic valve replacement (AVR). METHODS Data for all AVR and TAVI procedures between January 2006 and December 2012 in England and Wales were included. The number of procedures, patient characteristi...
