BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

Atrial fibrillation (AF) and valvular heart disease (VHD) frequently coexist and independently increase mortality1. Bioprosthetic valve implantation (surgical or transcatheter), is a common, increasingly utilized treatment for VHD2. Patients with AF and bioprosthetic valves require anticoagulation to prevent thromboembolic events. Non-vitamin K oral anticoagulants (NOACs) are safe and efficacious alternatives to vitamin K antagonists for anticoagulation in AF. However, guidelines recommend against NOACs in patients with bioprosthetic valves, citing a lack of supporting data...

Background Transcatheter valve-in-ring strategies have been developed to treat recurrent mitral regurgitation (MR) after failing surgical annuloplasty. However, suboptimal THV expansion with consecutive paravalvular leakage (PVL) is a procedure-immanent issue. Methods A rigid, saddle-shaped ring was cut at four locations. The segments were reconnected with pull-springs, rearranged to the original shape, and covered with a sewing cuff. The length of the annuloplasty ring construct, including extended pull-springs, was defined by the perimeter of an appropriate THV...

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...

Complications after transcatheter aortic valve implantation (TAVI) remain an important issue. This study aimed to evaluate the impact of systematic postprocedural multidetector computed tomography (MDCT) to detect subclinical complications after TAVI. From October 2013 to August 2015, a total of 135 patients who underwent transfemoral TAVI (n = 116) or transapical TAVI (n = 19) with Sapien XT and MDCT preprocedure and postprocedure were enrolled. Postprocedural MDCT findings were compared with the preprocedural MDCT findings...

Valve-in-valve implantation is generally successful in reducing paravalvular regurgitation (PVR) in cases in which the first transcatheter heart valve is deployed in a suboptimal location. We describe a case of severe PVR 2 months after implantation of a 26-mm Sapien XT valve (Edwards Lifesciences Inc, Irvine, CA) in the optimal location. Valve-in-valve implantation of a Sapien 3 valve (Edwards Lifesciences Inc), and enough left ventricular outflow tract tissue at the inflow edge the Sapien XT to appose the sealing cuff of the Sapien 3 combined for successful PVR treatment...

Transcatheter aortic valve implantation (TAVI) is the treatment of choice for inoperable and high-risk patients with severe aortic stenosis. Our objectives were to elucidate potential differences in clinical outcomes and safety between balloon-expandable versus self-expandable transcatheter heart valves (THV). We performed a retrospective cohort study of all transfemoral TAVI procedures in Ontario, Canada, from 2007 to 2013. Patients were categorized into either balloon-expandable or self-expandable THV groups...

Balloon-expandable percutaneous pulmonary valve systems using the Melody and Edwards SAPIEN transcatheter heart valves have been increasingly used instead of surgically implantable pulmonary valves. However, limited patients with right ventricular outflow tract (RVOT) lesions are suitable candidates for percutaneous pulmonary valve implantation (PPVI) using these systems after surgical correction of tetralogy of Fallot. Therefore, larger self-expandable valved-stents are being developed for native RVOT lesions...

The analysis is based on a finite element procedure to extract the contact forces between an implanted Nitinol stent and the surrounding host tissue using postoperative CT images. The methodology was applied for patients (N=46) which have undergone a TAVI procedure with the Medtronic CoreValve Revalving System (MCRS) to obtain corresponding deformation and force maps. The postoperative CT data were recorded for each patient in both systolic and diastolic phase of the heart cycle. Scalar parameters were defined, which map deformed geometry and contact force field to mechanically relevant quantities: radial dilatation, radial shape distortion, non-convex points, mean force, a force deviation measure and a pressure equivalent...
