The mainstay for the current treatment of severe aortic stenosis includes surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). In patients with high operative risk TAVI is established as first line therapy. New data on intermediate and low risk groups demonstrate at least non-inferiority of TAVI against SAVR, and in the near future a consistently rising number of transcatheter procedures may be anticipated. The purpose of this review is to outline the decision making process, hence to illustrate the diagnostic algorithm and to provide criteria for a differentiated approach against the background of recent data...

Aims: To analyse reasons, timing and predictors of hospital readmissions after transcatheter aortic valve implantation (TAVI). Methods and Results: Patients included in the Bern TAVI Registry between August 2007 and June 2014 were analysed. Fine and Gray competing risk regression was used to identify factors predictive of hospital readmission within 1 year after TAVI with bootstrap analysis for internal validation. Of 868 patients alive at discharge, 221 (25.4%) were readmitted within 1 year...

The VARC (Valve Academic Research Consortium) for transcatheter aortic valve replacement set the standard for selecting appropriate clinical endpoints reflecting safety and effectiveness of transcatheter devices, and defining single and composite clinical endpoints for clinical trials. No such standardization exists for circumferentially sutured surgical valve paravalvular leak (PVL) closure. This document seeks to provide core principles, appropriate clinical endpoints, and endpoint definitions to be used in clinical trials of PVL closure devices...

BACKGROUND: Little is known about patients with severe symptomatic aortic stenosis (AS) who receive medical management despite evaluation at a heart valve treatment center. OBJECTIVE: We identified patient characteristics associated with medical management, physician-reported reasons for selecting medical management, and patients' perceptions of their involvement and satisfaction with treatment selection. METHODS AND RESULTS: Of 454 patients evaluated for AS at 9 established heart valve treatment centers from December 12, 2013 to August 19, 2014, we included 407 with severe symptomatic AS...

OBJECTIVES: The aim of the study was to investigate the influence of the extent of computed tomography (CT)-based area and perimeter oversizing on the incidence and severity of paravalvular aortic regurgitation (PAR) for the Edwards SAPIEN 3 (Edwards Lifesciences, Irvine, California) device, using CT data and echocardiographic outcome data of the PARTNER II (Placement of AoRTic TraNscathetER Valves Trial II) SAPIEN 3 intermediate-risk cohort. BACKGROUND: Transcatheter heart valve (THV) sizing algorithms are device specific, requiring refinements for new valve designs...

Nickel-titanium alloys are commonly adopted for producing cardiovascular minimally invasive devices such as self-expandable stents, aortic valves and stent-grafts. These devices are subjected to cyclic loads (due to blood pulsatility, leg or heart movements), that can induce fatigue fracture, and may also be subjected to very large deformations (due to crimping procedure, a tortuous physiological path or overloads), that can induce material yield. Recently, the authors developed a new constitutive model that considers inelastic strains due to not-completed reverse phase transformation (not all the stress-induced martensite turns back to austenite) or/and plasticity and their accumulation during cyclic loads...

BACKGROUND/AIM: Transcatheter aortic valve implantation (TAVI) is an innovative approach to the treatment of aortic stenosis (AS) as an alternative to surgery in high-risk patients. Mean platelet volume (MPV) is considered an indicator of endothelial dysfunction, platelet function, and activation. In this study, we aimed to investigate MPV changes in patients undergoing TAVI. MATERIALS AND METHODS: This study included 100 patients diagnosed with symptomatic severe AS and treated with TAVI between July 2011 and August 2013...

Objective: To evaluate our experience following the introduction of a percutaneous program for endovascular treatment of aortic diseases using Perclose Proglide® assessing efficacy, complications and identification of potential risk factors that could predict failure or major access site complications. Methods: A retrospective cohort study during a two-year period was performed. All the patients submitted to totally percutaneous endovascular repair (PEVAR) of aortic diseases and transcatheter aortic valve implantation since we started the total percutaneous approach with the preclosure technique from November 2013 to December 2015 were included in the study...

AIMS: There is evidence for a lower mortality in female patients after transcatheter aortic valve implantation (TAVI), but the underlying reasons for the gender- specific differences in prognosis are not well understood. In particular, the role of left ventricular dysfunction is unclear. METHODS AND RESULTS: From January 2011 to December 2013, a total of 15,616 patients treated with TAVI were prospectively enrolled in the German Aortic Valve Registry (GARY). For the present analysis female TAVI patients (N=8,456) were compared with male TAVI patients (N=7,160) with a particular focus on left ventricular ejection function (LVEF)...

Aorto-left ventricular tunnel is an exceedingly rare congenital cardiac defect. Early surgical closure is the treatment of choice. Residual or recurrent tunnel and aortic valve insufficiency are well-recognised complications after surgical repair. In this article, we report on successful transcatheter closure of a residual aorto-left ventricular tunnel using an Amplatzer duct occluder in a 7-year-old boy. The outcome after 6 years of follow-up is encouraging.

OBJECTIVES: This study sought to develop a robust and definitive risk model for new permanent pacemaker implantation (PPMI) after SAPIEN 3 (third generation balloon expandable valve) (Edwards Lifesciences, Irvine, California) transcatheter aortic valve replacement (third generation balloon expandable valve TAVR), including calcification in the aortic-valvular complex (AVC). BACKGROUND: The association between calcium in the AVC and need for PPMI is poorly delineated after third generation balloon expandable valve TAVR...

BACKGROUND: Bundled Payments for Care Improvement (BPCI) initiatives were developed by Medicare in an effort to reduce expenditures while preserving quality of care. Payment model 2 reimburses based on a target price for 90-day episode of care postprocedure. The challenge for valve patients is the historically high (>35%) 90-day readmission rate. We analyzed our institutional cardiac surgical service line adaptation to this initiative. METHODS: On May 1, 2015, we instituted a readmission reduction initiative (RRI) that included presurgical risk stratification, comprehensive predischarge planning, and standardized postdischarge management led by cardiac nurse practitioners (CNPs) who attempt to guide any postdischarge encounters (PDEs)...

BACKGROUND AND PURPOSE: Silent ischemic embolic lesions are common after transcatheter aortic valve implantation (TAVI). The use of embolic protection devices (EPD) may reduce the occurrence of these embolic lesions. Thus, a quantitative overview and credibility assessment of the literature was necessary to draw a robust message about EPD. Therefore, the aim of this meta-analysis was to study whether the use of EPD reduces silent ischemic and clinically evident cerebrovascular events associated with TAVI...

BACKGROUND: The causes of procedural deaths after transcatheter aortic valve implantation (TAVI) have been scarcely detailed. AIMS: To assess these causes and their temporal trends since the beginning of the TAVI era. METHODS: From October 2006 to April 2014, 601 consecutive high-risk/inoperable patients with severe aortic stenosis underwent TAVI using the Edwards SAPIEN or SAPIEN XT or the Medtronic CoreValve. The transfemoral route was the default approach; the transapical or left subclavian approaches were alternative options...

OBJECTIVE: Transcatether aortic valve replacement (TAVR) has emerged as an acceptable alternative to surgical aortic valve replacement (SAVR) in patients with high-risk surgical profile. In this analysis, we compare both approaches in non-high surgical risk severe aortic stenosis. METHODS: Only studies comparing SAVR and TAVR and enrolling patients with low-intermediate risk were included from January 2000 through May 2016. Primary endpoints were assessed at 1 and 12months including: mortality, cerebrovascular accident (CVA) and myocardial infarction (MI)...
