BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. Though TAVR leads to a significant reduction in mortality, a notable amount of patients are re-hospitalized early after TAVR. Parameters or biomarkers predicting outcome are therefore needed to identify patients who benefit most. Specific monocyte subsets have been associated with cardiovascular diseases and were shown to possess prognostic value...

BACKGROUND: A comparison was made between the accuracy of and time saved by using novel automated software for pre-procedural computed tomography (CT) planning before transcatheter aortic valve implantation (TAVI) and manual methods. Preprocedural CT to assess aortic annulus dimensions and predict the optimal C-arm implant angle before TAVI can reduce complications related to incorrect prosthesis sizing and positioning. METHODS: A total of 61 consecutive patients underwent TAVI using either the SAPIEN XT or CoreValve prosthesis...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. METHODS: From July 2008 to May 2015, 856 transcatheter heart valves were implanted at our center (age: 80...

OBJECTIVES: The aims of this study were to determine plasma elevations of biomarkers of myocardial injury associated with transfemoral (TF) transcatheter aortic valve replacement (TAVR) and to evaluate their prognostic value. BACKGROUND: Increases in biomarkers of myocardial injury are a common finding after TAVR, but their clinical significance is unclear. METHODS: In 756 consecutive TF TAVR patients, cardiac high-sensitivity troponin I (hsTnI) and creatine kinase MB (CK-MB) levels were measured at pre-defined time points to assess the occurrence of myocardial injury (defined as 15 times the upper reference limit for hsTnI [≥1...

The safety and utility of GuideLiner catheters in complex percutaneous coronary interventions (PCI) has been well established. Patients with prior trans-catheter aortic valve replacement especially with CoreValve, who present for PCI, pose a unique set of challenges. Not only does the operator often encounter difficulty with selective engagement of coronary ostia through the struts of the CoreValve, but also the complex nature of the underlying CAD in this high-risk population. We present a case series to illustrate the use of GuideLiner catheter as an adjunctive tool for PCI in this patient population...

Nearly 20 years have passed from the concept to clinical development of percutaneous aortic valve replacement, starting from an idea considered "stupid" of Professor Alain Cribier in Rouen. After a first phase of compassionate implantation, large randomized trials PARTNER and COREVALVE US have allowed TAVI to impose itself in the European and American recommendations in patients inoperable or considered with high surgical risk. Next European recommendations on the management of valvular heart diseases expected in 2017 should take into account the positive results observed in intermediate risk patients in the PARTNER 2 and SURTAVI studies, recently adopted in the US recommendations...

The purpose of this study was to determine the predictability of QRS duration (QRSd) for temporary pacing catheter removal in patients implanted with CoreValve. Permanent pacemaker implantation is a known complication after transcatheter aortic valve replacement (TAVI) with CoreValve. Although post-TAVI QRSd is highly predictive for advanced atrioventricular block (AVB), management of delayed AVB after TAVI remains unclear. We conducted a multicentric, prospective study of 156 consecutive patients who underwent TAVI with CoreValve between December 2010 and January 2013...

OBJECTIVES: This study aimed to develop a procedure simulation platform for in vitro transcatheter aortic valve replacement (TAVR) using patient-specific 3-dimensional (3D) printed tissue-mimicking phantoms. We investigated the feasibility of using these 3D printed phantoms to quantitatively predict the occurrence, severity, and location of any degree of post-TAVR paravalvular leaks (PVL). BACKGROUND: We have previously shown that metamaterial 3D printing technique can be used to create patient-specific phantoms that mimic the mechanical properties of biological tissue...

New generation devices for transcatheter aortic valve replacement have been optimized to improve clinical outcome. We compared procedural, in-hospital, 30 days and 12 months outcome of the new generation repositionable Boston Lotus Valve and the balloon-expandable Edwards Sapien 3 valve with the last generation self-expandable Medtronic CoreValve and the balloon-expandable Edwards Sapien XT. Between 2010 and 2015 consecutive patients treated with the Medtronic CoreValve (N = 100), Edwards Sapien XT (N = 100), Edwards Sapien S3 (N = 100) and Boston Lotus device (N = 100) were enrolled...

We here report the case of a stenosis of the CoreValve(®) system due to reduced mobility of prosthesis cusps for which a surgical replacement of the aortic valve was proposed. The exact mechanism leading to this impaired mobility of the leaflets is yet to be determined. We also underline the fact a transcatheter aortic valve implantation (TAVI) device can be replaced by a surgical replacement without excessive operative risks despite the patient being initially considered as high-risk.

Transcatheter aortic valve implantation (TAVI) is an alternative therapeutic option for severe aortic stenosis. Aortic regurgitation (AR) is commonly observed after TAVI and increases the mortality rate. We hypothesized that the influence of significant AR, defined as that more severe than mild AR, on survival rate after TAVI might differ according to the baseline left ventricular ejection fraction (LVEF) and N-terminal pro-B-type natriuretic peptide (NT-pro BNP) level. We categorized 856 patients who underwent transfemoral TAVI into 2 groups according to their baseline LVEF (<40 and ≥40%) and NT-pro BNP levels (≤5000 and >5000 pg/mL)...
