In recent years, transcatheter aortic valve implantation (TAVI) has been considered a novel option for the management of surgically high-risk patients requiring aortic valve replacement. Presently described is a case of acute coronary syndrome (ACS) managed with a challenging primary percutaneous coronary intervention (PCI) shortly after a valve-in-valve TAVI intervention. This case highlights 2 important issues: PCI may be an option for the management of coronary heart disease in patients after TAVI even in the setting of demanding features associated with coronary osteal engagement, and secondly, TAVI may serve as a potential risk factor for future coronary ischemic syndromes, largely due to its potential adverse effects on coronary flow dynamics, etc...

Performing transcatheter aortic valve implantation in the presence of aneurysmatic aortopathy is widely contraindicated; however, it needs to be taken into account as bailout strategy in selected patients. Deliberate preoperative assessing measurements become the crucial key element in this context. After meticulous valve selection, retrograde access is obtained via the right subclavian artery additionally serving as backup arterial cannulation site in case of conversion. TAVI is then performed via the transapical route...

Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) is associated with increased mortality. As significant hemodynamic improvement may occur with relief of aortic stenosis, we hypothesized that TAVI patients may demonstrate the opposite phenomena: acute kidney recovery (AKR). We studied the incidence and predictors of AKR in post-TAVI patients. A total of 366 consecutive patients underwent TAVI (January 2012 to January 2017) at a single center. We defined AKR as a 25% improvement in glomerular filtration rate (GFR) at 48 hours after TAVI...

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...

OBJECTIVES: Reducing the rate of postoperative stroke after cardiac surgery remains challenging, especially in patients with occlusive cerebrovascular disease. Angioplasty in all patients with high-grade carotid artery stenosis has not been shown to be effective in reducing the post-surgical stroke rate. In this study, we present the initial results of a different approach using selective carotid angioplasty only in patients with poor intracranial collaterals. METHODS: We conducted a single-centre study to assess the safety of this procedure...

Elevated carbohydrate antigen 125 (CA125) and N-terminal pro-brain natriuretic peptide (NTproBNP) have been associated with adverse outcome after transcatheter aortic valve implantation (TAVI). This study performs a comparison of both biomarkers for prognosis after TAVI. The study includes 363 patients. The primary end point was all-cause death or readmission for worsening congestive heart failure within 1 year after TAVI, and this end point occurred in 16% of the population. The optimal cutoff to predict the primary end point was 18...

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: 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...
