To compare structural valve deterioration (SVD) among bioprosthetic aortic valve types, a PubMed search found 54 papers containing SVD-free curves extending to at least 10 years. The curves were digitized and fit to Weibull distributions, and the mean times to valve failure (MTTF) were calculated. Twelve valve models were collapsed into four valve types: Medtronic (Medtronic, Minneapolis, MN) and Edwards (Edwards Lifesciences, Irvine, CA) porcine; and Sorin (Sorin Group [now LivaNova], London, United Kingdom) and Edwards pericardial...

OBJECTIVES: To evaluate balloon-expandable and self-expanding third-generation transcatheter aortic valve replacement (TAVR) devices according to patient selection criteria and outcomes. BACKGROUND: Two competing third-generation TAVR technologies are currently commercially available in the US. There are no published head-to-head comparisons of the relative performance of these two devices. METHODS: 257 consecutive patients undergoing TAVR with a third-generation balloon-expandable (Edwards Sapien 3) or self-expanding device (Medtronic CoreValve Evolut R) at a single US medical center were included...

Transcatheter aortic valve implantation (TAVI) is a validated technique for the treatment of aortic valve stenosis in patients with high surgical risk or inoperable. We present the case of an 80-year-old woman with severe aortic valve stenosis (mean gradient 55 mmHg), mild surgical risk, who refused traditional surgery. We implanted a Lotus Sadra 25 mm (Boston Scientific, Marlborough, MA, USA) via the transfemoral route. During pull back delivery, the patient experienced interscapular pain with angiographic evidence of type B aortic dissection effectively treated by implanting a vascular endoprosthesis Valiant 30 x 150 mm (Medtronic Vascular, Santa Rosa, CA, USA)...

OBJECTIVE: Valve-in-valve procedures using transcatheter aortic valves are increasingly performed to treat degenerated bioprosthetic surgical aortic valves because they are less invasive than redo aortic valve replacement. The objective of this study is to quantify the changes in aortic sinus blood flow dynamics before and after a valve-in-valve procedure to gain insight into mechanisms for clinical and subclinical thrombosis of leaflets. METHODS: A detailed description of the sinus hemodynamics for valve-in-valve implantation was performed in vitro...

BACKGROUND: The causes of procedural deaths after transcatheter aortic valve implantation (TAVI) have been scarcely detailed. AIMS: To assess these causes and their temporal trends since the beginning of the TAVI era. METHODS: From October 2006 to April 2014, 601 consecutive high-risk/inoperable patients with severe aortic stenosis underwent TAVI using the Edwards SAPIEN or SAPIEN XT or the Medtronic CoreValve. The transfemoral route was the default approach; the transapical or left subclavian approaches were alternative options...

Aortic valve replacement with sutureless valves has many potential applications including in redo surgery, minimally invasive scenarios, and heavily calcified aortic roots. Herein we report a case of the development of an aorto-right atrial fistula after replacement of a Medtronic Freestyle stentless subcoronary bioprosthesis (Medtronic Inc, Minneapolis, MN) with a Perceval sutureless valve (LivaNova PLC, London, UK). This eventually necessitated repair with repeat surgery and aortic valve replacement with a stented valve...

Percutaneous pulmonary valve implantation (PPVI) is a relatively new method of treating patients with right ventricular outflow tract (RVOT) dysfunction after surgical repair of congenital heart disease. Since its introduction in 2000 by Bonhoeffer, more than ten thousand PPVI procedures have been performed worldwide. Indications for PPVI have been adapted from those accepted for surgical intervention. Two types of valves are being used: Melody Medtronic available in diameters 16 mm and 18 mm and the family of Edwards SAPIEN valves 23, 26 and 29...

BACKGROUND: The use of transcatheter aortic valve implantation (TAVI) following the introduction of Nitinol autoexpandable devices has spread rapidly during recent years. In addition, cardiac surgery has been revolutionized due to the use of Nitinol-based sutureless prostheses for aortic valve replacement (AVR). During the same period, however, permanent pacemaker (PPM) implantation has emerged as a frequent complication. The study aim was to identify the risk factors of PPM following the implantation of a Nitinol self-expanding prosthesis (for AVR or TAVI)...

The role of imaging in the diagnosis of valvular heart disease is well established through years of investigation and validation. However, the role of imaging in guiding the treatment decision-making for valvular heart disease is less well established, and there is a striking paucity of randomized trial data to help inform these decisions. Given this relative absence of randomized trial data, the present article highlights some of the most important knowledge gaps and defines meaningful opportunities for the field to help advance the care of patients with valvular heart disease in a cost-effective fashion...

Transcatheter aortic valve implantation (TAVI) has become an important treatment in high surgical risk patients with severe aortic stenosis (AS), whose complications need to be managed promptly. The authors report the case of an 86-year-old woman presenting with severe symptomatic AS, rejected for surgery due to advanced age and comorbidities. The patient underwent a first TAVI, with implantation of a Medtronic CoreValve(®), which became dislodged and migrated to the ascending aorta. Due to the previous balloon valvuloplasty, the patient's AS became moderate, and her symptoms improved...

BACKGROUND: Right bundle branch block is an established predictor for new conduction disturbances and need for a permanent pacemaker (PPM) after transcatheter aortic valve replacement. The aim of the study was to evaluate the absolute rates of transcatheter aortic valve replacement related PPM implantations in patients with pre-existent right bundle branch block and categorize for different transcatheter heart valves. METHODS AND RESULTS: We pooled data on 306 transcatheter aortic valve replacement patients from 4 high-volume centers in Europe and selected those with right bundle branch block at baseline without a previously implanted PPM...
