BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become a therapeutic alternative for patients presenting with severe symptomatic aortic stenosis and considered at high-surgical risk. Paravalvular leak (PVL), conduction disorders, and coronary obstruction remain unresolved procedure-related complications. The aim of this manuscript was to report the first North American experience with the ACURATE-neo(TM) aortic bioprosthesis and its ACURATE-TF(TM) delivery system (Symetis S...

OBJECTIVES: The published literature has extensively documented clinical benefit derived from transcatheter aortic valve implantation (TAVI) in high-risk patients using self-expanding current-generation transfemoral (TF) transcatheter heart valves (THVs). However, it has also demonstrated apparent shortcomings such as paravalvular leakage (PVL) or need for permanent pacemaker (PM) implantation. We here present a case-matched analysis of acute 30-day outcomes using a novel nitinol-based THV (Symetis Acurate Neo TF™), which may overcome some limitations of currently used devices...

Transcatheter aortic valve implantation (TAVI) was initially developed for the treatment of calcific aortic stenosis. In the recent years, however, TAVI has been used to treat selected patients with pure, severe AR. We report successful transfemoral implantation of a Symetis ACURATE neo bioprosthesis in a severely symptomatic, 87-year-old woman with pure AR and major comorbidities. We decided to use the ACURATE neo bioprosthesis for some of its features appeared to us as potentially useful in the setting of pure AR: the stabilization arches ensure perfect coaxial alignment and extreme stability of the device during deployment, and the "waist" and the skirt were considered useful to obtain a good seal in the absence of significant valvular and annular calcifications...

Transcatheter aortic valve implantation (TAVI) in the presence of a mechanical mitral valve (MMV) prosthesis is still challenging because of the rigid mitral frame within the aortomitral curtain. Moreover, low-lying coronary ostia represent a hazardous problem of coronary obstruction, especially in narrow or porcelain aortic roots. The present case demonstrates the successful management of 2 challenging anatomical issues, the rigid cage of the MMV and the low-lying left main coronary ostium (LMCO), with the implantation of the ACURATE-TA bioprosthesis (Symetis SA, Ecublens, Switzerland)...

The Symetis ACURATE TA and ACURATE neo technology is a novel transcatheter heart valve for treatment of aortic valvular stenosis. This review illustrates the implantation steps, which are designed for an easy and intuitive transapical and transfemoral TAVI procedure. The most important difference to other self-expanding platforms is the top-down deployment with minimal protrusion of the stent towards the left ventricular outflow tract. In addition, the supra-annularly placed porcine leaflets provide very low gradients and the pericardial skirt acts very effectively to seal against paravalvular leaks...

AIMS: Calcification of the device landing zone is linked to paravalvular regurgitation after transcatheter aortic valve implantation (TAVI). The mechanisms remain incompletely understood and the performance of next-generation transcatheter heart valves (THV) has not been investigated. We evaluated the impact of calcification patterns on residual aortic regurgitation (AR) after TAVI with different THV in patients with severe aortic stenosis. METHODS AND RESULTS: TAVI was performed in 537 patients at two centres...

Transcatheter treatment of patients with degenerated aortic valve stentless prosthesis and low proximal coronary ostia to the aortic annulus remain a challenge because of the elevated risk for coronary obstruction. Newer generation transcatheter aortic valve devices that engage and pull the aortic valve calcium towards the aortic annulus may be beneficial in these patients. We present a case of successful treatment of a degenerated tubular stentless prosthesis with low coronary ostia with a Symetis Acurate TA prosthesis...

OBJECTIVE: Since the beginning of the transcatheter aortic valve implantation (TAVI) era, many prosthetic valves have entered clinical practice. TAVI prostheses differ regarding stent design and some may potentially interfere with diagnostic or interventional catheters. The aim of our analysis was to evaluate the feasibility of coronary angiography (CA) or percutaneous coronary intervention (PCI) in patients with prior TAVI. METHODS: From 2011 to 2014, 1,000 patients were treated by TAVI at our center using eight different valve prostheses (Symetis ACURATE TA and ACURATE TF; Medtronic CoreValve and Engager; JenaValve, SJM Portico; Edwards Lifesciences SAPIEN and SAPIEN XT)...

Transapical transcatheter aortic valve implantation (TA-TAVI) is the recognized first choice surgical TAVI access. Expansion of this well-established treatment modality with subsequent broader patient inclusion has accelerated development of second-generation TA-TAVI devices. The Swiss ACURATE TA Symetis valve allows for excellent anatomical positioning, resulting in a very low incidence of paravalvular leaks. The self-expanding stent features an hourglass shape to wedge the native aortic valve annulus. A specially designed delivery system facilitates controlled release aided by tactile operator feedback...

OBJECTIVES: This study sought to evaluate the self-expandable ACURATE TA device (Symetis SA, Ecublens, Switzerland) in a cohort of patients with pure aortic regurgitation (AR). BACKGROUND: Transcatheter aortic valve replacement (TAVR) has been initially considered as an alternative for high-risk patients with aortic stenosis. Although the current experience is limited, TAVR might be also an alternative to treat patients with pure, severe AR. METHODS: Between April 2012 and December 2013, a total of 8 high-risk patients with pure, severe AR were enrolled (grade III+)...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has proven to be a valuable alternative to conventional surgical aortic valve replacement in high risk and surgically in operable patients who suffer from severe symptomatic aortic stenosis. However, a significant number of complications, associated with both the learning curve and device specificity, have required attention and subsequent improvement. The Symetis transapical TAVR system is a self-positioning bioprosthesis composed of a non-coronary leaflet of surgical quality porcine tissue valve sewn into a self-expanding nitinol stent that iscovered with a PET-skirt...

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) has become an established procedure in patients with aortic stenosis and high surgical risk. Experience with first-generation transcatheter heart valves (THVs) is broad but limitations, e.g. paravalvular regurgitation, have been demonstrated. Much hope rests on the recently Conformité Européenne mark approved next-generation devices to improve results in these patients. However, apart from the initial approval studies, clinical data with these new devices are still scarce...

REVIEW
Siyamek Neragi-Miandoab, Edvard Skripochnik, Arash Salemi, Leonard Girardi
The most widely used heart valve worldwide is the Edwards Sapien, which currently has 60% of the worldwide transcatheter aortic valve implantation (TAVI) market. The CoreValve is next in line in popularity, encompassing 35% of the worldwide TAVI market. Although these two valves dominate the TAVI market, a number of newer transcatheter valves have been introduced and others are in early clinical evaluation. The new valves are designed to reduce catheter delivery diameter, improve ease of positioning and sealing, and facilitate repositioning or removal...
