Results of transcatheter aortic valve implantation (TAVI) for treatment of severe noncalcific isolated aortic regurgitation (AR) complicated by advanced heart failure or cardiogenic shock has been previously reported only in isolated case reports. Current self-expanding transcatheter aortic valves are designed to treat aortic valve stenosis, and have also been implanted in cases of severe AR due to degenerated bioprosthesis and in very few cases of native aortic valves. We report 13 consecutive inoperable patients with noncalcific, pure AR, and advanced heart failure treated with emergency percutaneous transfemoral implantation with self-expandable CoreValves at our institution between July 2012 and September 2017...

AIM: To evaluate the incidence, risk factors, and prognostic implications of contrast medium-induced acute kidney injury (CI-AKI) in patients undergoing transcatheter aortic valve implantation (TAVI) evaluation. MATERIALS AND METHODS: Datasets from 98 out of 207 consecutive patients referred for multidetector computed tomography (MDCT) for TAVI evaluation were eligible for evaluation and were analysed retrospectively. The incidence of CI-AKI was correlated to outcome and to potential risk factors: kidney function (estimated glomerular filtration rate [eGFR]), heart failure, diabetes, amount of contrast medium, and duration of examination period...

Objectives: Transcatheter aortic valve implantation (TAVI) and transcatheter mitral valve repair (TMVR) are increasingly used for managing patients with valvular heart disease to whom surgery presents a high-risk. As these are costly procedures, a systematic review of studies concerned with their economic assessment was undertaken. Methods: The search was performed in PubMed and the Cochrane Library and followed recommended methodological steps. Studies were screened and their data were retrieved and were synthesized using a narrative approach...

Pre-procedural planning is the key element of transcatheter aortic valve implantation (TAVI). Multislice computed tomography of the chest, abdomen and pelvis with the ability to perform a 3-dimensional reconstruction has become the cornerstone of pre-procedural planning. We would like to encourage TAVI operators (interventional cardiologist and surgeons) to get involved in imaging. All TAVI operators should know how to assess the annulus, the annular root, and the iliofemoral access. We strongly believe that this will improve outcomes of this evolving procedure...

INTRODUCTION: Natriuretic peptides are ubiquitously used for diagnosis, follow-up and prognostic assessment in various heart conditions. N-terminal pro-brain natriuretic peptide (NT-proBNP) correlates with aortic stenosis severity, however its significance after transcatheter aortic valve implantation (TAVI) is not well established. AIM: We aimed to assess the prognostic value of NT-proBNP at one year in patients undergoing TAVI. METHODS: This single-center retrospective analysis included 151 patients in whom both baseline and one-month post-procedure NT-proBNP were measured, from 206 consecutive patients undergoing TAVI between November 2008 and December 2014...

Aims: We assessed the geometry of transcatheter heart valve (THV) and valve function associated with SAPIEN 3 implantation in patients with bicuspid aortic valve (BAV) stenosis. Methods and results: We included 280 consecutive patients who had a contrast computed tomography (CT) before and after transcatheter aortic valve implantation (TAVI) in our institution. Each THV was assessed by CT at five cross-sectional levels: inflow, annulus, mid, sinus, and outflow. The geometry of THV was assessed for eccentricity (1 - minimum diameter/maximum diameter) and expansion (CT derived external valve area/nominal external valve area)...

AIMS: Empirically, transfemoral (TF) approach is the first choice for transcatheter aortic valve implantation (TAVI). We aimed to investigate whether transubclavian (TSc) and TF approaches present comparable major outcomes according to current evidence. METHODS: We systematically searched PubMed, EMBASE, and Cochrane database for studies with symptomatic aortic stenosis patients who underwent TAVI through TF or TSc/axillary access from January/2006 to January/2017...

Moderate or severe paravalvular regurgitation after transcatheter aortic valve implantation (TAVI) is frequently associated with a loss of high-molecular-weight multimers of von Willebrand factor (VWF) and a reduced VWF collagen-binding capacity. It is unclear whether this phenomenon can also be observed in patients with mild paravalvular regurgitation, and whether there are differences between patients undergoing conventional aortic valve replacement (AVR) or TAVI. We analysed the multimeric structure of VWF and the ratio of VWF collagen-binding capacity to VWF antigen pre- and postoperatively in 12 patients scheduled for AVR and in 31 patients scheduled for TAVI...

Coarctation of the aorta (CoA) is a relatively common congenital heart anomaly, and bicuspid aortic valve (BAV) is a common congenital heart disease that coexists with CoA. In larger children and adults with CoA, transcatheter intervention has gained acceptance, but for surgical high-risk patients with aortic stenosis, the use of transcatheter aortic valve implantation (TAVI) has been established. Recently, although favorable data have been reported for TAVI when treating BAV, simultaneous transcatheter intervention for CoA and BAV will prove to be a challenge because of the unique anatomy involved requires multiple procedural steps and also has problems of site access...

BACKGROUND: Left ventricular (LV) perforation is one of the rare and most serious complications of transcatheter aortic valve implantation (TAVI). The study aim was to determine the pathophysiological factors associated with this serious complication. METHODS: A retrospective study was conducted of pathophysiological factors shown in echocardiograms and computed tomography angiograms performed preoperatively in patients who developed LV perforation during transfemoral TAVI (study group) with regards to anatomic and functional variables...

BACKGROUND: Worldwide, there is increased use of bioprosthetic valves in the aortic position. Part of this increase has been patient-driven for quality of life reasons. More recently, bioprosthetic valves have been chosen by progressively younger patients, with a strategy of performing a valve-in-valve TAVI if the prosthesis should wear out. Thus, a review was undertaken of the present authors' experience with patients whose first two aortic valve replacements (AVRs) were with bioprosthetic valves...

BACKGROUND:  Transcatheter aortic valve implantation (TAVI) has evolved into an alternative procedure to surgical valve replacement for high-risk patients with aortic valve stenosis. Despite technical innovations, there is still a risk of complications during and after the intervention. After a TAVI procedure, ECG-gated multidetector computed tomography (MDCT) plays an important role in the early diagnosis of local complications. In this article, we explain for the first time how the technical acquisition of MDCT in the region of the aortic root is performed as post-interventional control of the TAVI prosthesis...

As transcatheter aortic valve implantation (TAVI) requires multidisciplinary collaboration, operators and the entire heart team must overcome a steep learning curve. A web-based screening and traditional on-site proctoring system were developed for the introduction of TAVI in Japan. To assess the learning curve involved with the introduction of TAVI under the supervision of a novel proctoring system. We divided 749 consecutive patients enrolled in the OCEAN-TAVI study between October 2013 and August 2015 into the trans-femoral (TF, n = 608) and transapical (TA, n = 141) approach groups to compare outcomes in patients who underwent TAVI during the early proctoring period (proctoring group) and after the procedures began to be performed independently (independent group)...

Peripheral artery disease plays a pivotal role for access site selection in transcatheter aortic valve replacement (TAVR). Abnormal ankle-brachial index (ABI) is a generalized mortality marker in many cardiovascular scenarios. However, the long-term outcomes in high-risk TAVR populations remain unclear. We investigated the association between low ABI and 2-year outcome after TAVR. Of 1613 patients enrolled in the OCEAN-TAVI registry, 1458 (90.4%) who underwent ABI before TAVR were divided into groups: patients with (1) ABI ≥ 0...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is increasingly being offered to high-risk patients with symptomatic aortic valve stenosis. Recent reports have suggested a high incidence of subclinical leaflet thrombosis following bioprosthestic aortic valve replacement. We report the frequency and clinical presentation of leaflet thrombosis identified by cardiac CT in patients referred for follow-up contrast enhanced CT angiography following TAVI. METHODS: 91 consecutive patients referred for follow-up contrast-enhanced CT angiography following TAVI were screened for inclusion in this analysis...

BACKGROUND AND AIMS: Bleeding complications are frequent and independently impact mortality after TAVI. Thromboelastography (TEG) measures viscoelastic properties of clot formation and is currently best known for perioperative management to reduce blood transfusion in cardiac surgery. We sought to determine whether TEG may be predictive of bleeding in patients treated with TAVI. METHODS AND RESULTS: Overall, 54 consecutive patients with severe aortic stenosis treated with TAVI were prospectively included...
