OBJECTIVES: To evaluate the feasibility of coronary procedures after transcatheter aortic valve implantation (TAVI) with the CoreValve™ device. BACKGROUND: Due to its design, CoreValve™ prosthesis may interfere with coronary procedures. Data on this issue are sparse. METHODS: Between 2007 and 2015, 550 patients underwent CoreValve™ TAVI in our hospital. Among them, 16 underwent coronary angiogram after TAVI and were included in our retrospective study...

We would like to present in this paper a patient with severe aortic valve stenosis referred to our department for surgical aortic valve replacement. In this patient, it was intraoperatively detected an unexpected heavily calcified porcelain ascending aorta. We present the treatment options in this situation, the difficulties affronted intraoperatively, the significance of the preoperative chest computed tomography scan and the use of the Perceval S aortic valve as ideal bioprosthesis implantation. This is a self-expanding, self-anchoring, and sutureless valve with a wide indication in all patients requiring aortic bioprosthesis...

OBJECTIVE: Coronary obstruction remains a challenging complication of transcatheter aortic valve replacement; however, a new self-expanding transapical prosthesis may reduce this risk. The purpose of this study was to evaluate the early 1-year outcomes of patients with low coronary heights who received the Acurate TA bioprosthesis (Symetis, Ecublens, Switzerland). METHODS: Between May 2014 and April 2015, 30 consecutive patients (aged 85 ± 6 years, 63% were female, Society of Thoracic Surgeons score 8...

OBJECTIVE: Native aortic valve calcium and transcatheter aortic valve oversize have been reported to predict pacemaker implantation after transcatheter aortic valve insertion. We reviewed our experience to better understand the association. METHODS: We retrospectively reviewed the records of 300 patients with no prior permanent pacemaker implantation who underwent transcatheter aortic valve insertion from November 2008 to February 2015. Valve oversize was calculated using area...

AIMS: Data on procedural and clinical outcomes after transcatheter aortic valve implantation (TAVI) with the new generation self-expanding Medtronic Evolut-R prosthesis in comparison with its predecessor, the Medtronic CoreValve, are scarce. METHODS AND RESULTS: In a nationwide, prospective, multi-center cohort study outcomes of consecutive transfemoral TAVI patients treated with the new- generation Medtronic Evolut-R (September 2014 - February 2016) and the Medtronic CoreValve (February 2011 - February 2016) were investigated...

BACKGROUND: Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. OBJECTIVES: This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery...

This study presents the in vitro hydrodynamic assessment of the TRISKELE, a new system suitable for transcatheter aortic valve implantation (TAVI), aiming to mitigate the procedural challenges experienced with current technologies. The TRISKELE valve comprises three polymeric leaflet and an adaptive sealing cuff, supported by a novel fully retrievable self-expanding nitinol wire frame. Valve prototypes were manufactured in three sizes of 23, 26, and 29 mm by automated dip-coating of a biostable polymer, and tested in a hydrodynamic bench setup in mock aortic roots of 21, 23, 25, and 27 mm annulus, and compared to two reference valves suitable for equivalent implantation ranges: Edwards SAPIEN XT and Medtronic CoreValve...

OBJECTIVES: This study sought to summarize available evidence on transcatheter aortic valve replacement (TAVR) for the treatment of native pure aortic regurgitation (AR). BACKGROUND: Surgical aortic valve replacement (SAVR) is the gold standard for the treatment of AR. However, case series of high-risk patients undergoing TAVR for native pure AR were reported. METHODS: We systematically searched Medline, Embase, and Scopus for reports of at least 5 patients with native pure AR undergoing TAVR...

This study assessed the influence of the evolution in Transcatheter Aortic Valve Implantation technology on cerebral oxygenation. Cerebral oxygenation was measured continuously with Near-Infrared Spectroscopy and compared retrospectively between balloon-expandable, self-expandable and differential deployment valves which were implanted in 12 (34%), 17 (49%) and 6 patients (17%), respectively. Left and right SctO2 values were averaged at four time points and used for analysis (i.e. at baseline, balloon-aortic valvuloplasty, valve deployment, and at the end of the procedure)...

BACKGROUND: A major drawback of the transcatheter aortic valve replacement (TAVR) procedure using the self-expandable Medtronic CoreValve (MCV) prosthesis is the high incidence of conduction disturbances and the need for postprocedural permanent pacemaker (PPM) implantation. The depth of prosthesis implantation may be an important contributing factor. The study aim was to determine the relationship between angiographic measurements of the MCV prosthesis depth and the occurrence of new conduction disturbances and need for PPM after TAVR...

BACKGROUND: Aortic regurgitation (AR) is a frequent and life-limiting complication after transcatheter aortic valve implantation (TAVI). The study aim was to relate post-TAVI AR, using a self-expandable stent, to detailed baseline anatomical and morphological characteristics of the native aortic valve. METHODS: A total of 82 patients (40 males, 42 females; mean age 80 ± 7 years) who received a Medtronic CoreValve implant was included. Aortic root morphology, aortic annulus and implant size mismatch, implant position, extent of aortic annulus and leaflet calcification, the connected sub-annular calcification volume, and their distribution were quantified based on computed tomography scan analysis...
