BACKGROUND: Transcatheter aortic valve implantation has become an accepted treatment modality for inoperable or high-risk surgical patients with symptomatic severe aortic stenosis. CASE PRESENTATION: We report the case of a 70-year-old white man who was treated for severe symptomatic aortic regurgitation using transcatheter aortic valve implantation from the apical approach. Because of recurrent cardiac decompensation 4 weeks after implantation he underwent the implantation of a left ventricular assist device system...

The first case of a novel JenaValve design using the transfemoral approach in a 78 year old female patient with pure aortic regurgitation is described. The implantation was successfully performed with excellent haemodynamics and good clinical outcome at 6 months follow up. The technology is especially appealing in non-calcified anatomies due to the clipping mechanism that has been previously utilized in the transapical design.

A 40-year-old man underwent 4 aortic surgeries because of endocarditis and subsequent prosthesis dehiscence. At the last recurrence he presented with acute severe aortic regurgitation of a Pericarbon Freedom (LivaNova plc, London, UK) stentless bioprosthesis and a morphologically disarranged aortic root. He also presented with left ventricular dysfunction and a very low origin of the left coronary artery. Therefore, a fifth redo aortic valve replacement was considered at high surgical risk. Accordingly, before listing the patient for a heart transplantation, a transcatheter valve-in-valve implantation with the JenaValve (JenaValve Technology, GmbH, Munich, Germany) prosthesis was performed...

OBJECTIVES: Transcatheter aortic valve replacement (TAVR) is an established therapy for patients with aortic stenosis (AS) at high surgical risk. The JenaValve™ is a second-generation, self-expanding transcatheter heart valve (THV), implanted through transapical access (TA). During stent deployment, a specific 'clipping-mechanism' engages native aortic valve cusps for fixation. We present 1-year outcomes of the JUPITER registry, a post-market registry of the JenaValve for TA-TAVR. METHODS: The JUPITER registry is a prospective, multicentre, uncontrolled and observational European study to evaluate the long-term safety and effectiveness of the Conformité Européenne-marked JenaValve THV...

BACKGROUND: Paravalvular leakage (PVL) is a known complication of transcatheter aortic valve implantation (TAVI) and is associated with poor outcome. Besides balloon-post-dilatation, valve-in-valve (ViV) procedures can be taken into consideration to control this complication. Herein we present initial experience with use of the latest generation balloon-expandable Edwards Sapien 3® (S3) transcatheter heart valve (THV) for treatment of failing THVs. METHODS: Between 01/2014 and 12/2014 three patients (two male, age: 71-80 y, log EUROScore I: 11...

Transcatheter Aortic Valve Replacement (TAVR) is performed in patients who are poor surgical candidates. Many patients have inadequate femoral access, and alternative access sites have been used such as the transapical approach discussed in this paper. We present an elderly and fragile patient not suitable for surgery for unacceptable high risk, including poor ventricular function, previous myocardial infarction with percutaneous coronary intervention, pericardial effusion, and previous cardiac surgery with replacement of mechanical mitral valve...

Coronary obstruction during transcatheter aortic valve implantation is a potentially life-threatening complication. Most of the widely used transcatheter heart valves require a certain distance between the basal aortic annular plane and the origins of the coronary arteries. We report the case of a successful valve-in-valve procedure with an Edwards SAPIEN XT valve into a JenaValve as a bail-out procedure in a patient with a low originating left coronary artery and a heavily calcified aorta.

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 valve implantation is a novel interventional technique, which was developed as an  alternative therapy for surgical aortic valve replacement in inoperable patients with severe aortic stenosis. Despite limited experience in using transcatheter valve implantation for mitral and aortic regurgitation, transapical transcatheter aortic valve implantation and valve-in-valve implantation for degenerated mitral valve bioprosthesis can be performed in high-risk patients who are not candidates for conventional replacement surgery...

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)...

PURPOSE: The assessment of aortic annular size is critical, and inappropriate sizing is thought to be a main reason of paravalvular aortic regurgitation. Multidetector computed tomograph is associated with the risk of contrast nephropathy. For optimal evaluation of the complex structure of the aortic annulus, three-dimensional (3D)-methods should be used. We therefore sought to determine the value of 3D-transoesophageal echocardiography (3D-TEE) for appropriate sizing. METHODS: Hundred and one patients (mean age 81·4 years) with symptomatic aortic valve stenosis (AS) and high surgical risk profile (mean log...

While transcatheter aortic valve replacement( TAVR) has spread rapidly all over the world for highrisk patients with severe aortic stenosis (AS), SAPIEN XT was approved in Japan in October 2013. Since that, approximately 400 TAVR cases were performed in Japan. In our institute, we have performed 164 cases since first case in Japan in 2009 and have achieved satisfactory early results(30-day mortality:1.2%). At the same time, however, simultaneously various TAVR-related complications including a paravalvular leak, stroke, vascular complications, and coronary obstruction were observed...
