To report on 2 rare cases of balloon-expandable transfemoral transcatheter aortic valve implantation, where a trapped balloon led to complications requiring acute intervention. Both patients were elderly with increased risk profile and had been discussed by the heart team. After standard positioning of the valves using a transfemoral approach, retrieval of the pusher before deployment of the valve was missed. In 1 patient, rapid pacing was continued, the balloon deflated, the pusher pulled back and the balloon repositioned and reinflated...

BACKGROUND: Rapid deployment aortic valve replacement (RDAVR) has emerged as an attractive alternative to conventional aortic valve replacement. This single-center study directly compared two commercially available rapid deployment valves with regard to clinical outcomes, valve-related complications, and hemodynamic performance. METHODS: A total of consecutive 156 patients underwent RDAVR with the Intuity Elite (Edwards Lifesciences, Irvine, CA [Intuity group, n = 117] or the Perceval S (Sorin Group Italia Srl, Saluggia, Italy [Perceval group, n = 39]) between September 2012 and March 2016 at our institution...

Rapid-deployment valves could potentially reduce cross-clamping time and cardiopulmonary bypass time in complex combined procedures and facilitate minimally invasive surgery. This propensity-matched study compared clinical and echographic outcomes between patients undergoing rapid-deployment aortic valve replacement (RDAVR) compared with stented biological aortic valve replacement (SAVR), with or without concomitant procedures. Between 2012 and 2015, 61 consecutive patients (age 70 ± 7 years, European System for Cardiac Operative Risk Evaluation [EuroSCORE] II 2...

OBJECTIVE: Clinical studies have demonstrated excellent hemodynamic performance of rapid deployment aortic valves; however, few studies have directly compared the performance of these valves with conventional bioprosthetic valves. Thus, the hemodynamic function of the EDWARDS INTUITY valve (rapid deployment valve) was compared with the Edwards Magna Ease valve in vitro (Edwards Lifesciences Corp, Irvine, CA USA). METHODS: Elastomeric material was used to create an aortic root model that included a left ventricular outflow tract and aortic annulus...

The success and continued rapid clinical integration of transcatheter valve technologies relies on imaging modalities to guide safe and effective device deployment. In particular, cardiac imaging, using both echocardiography and CT, is an integral resource for the multidisciplinary team. These modalities can provide valuable insight for the proceduralist at each stage of transcatheter-based valve insertion, as they can be used reliably to define the anatomy of interest and its relationship to surrounding structures, determine accurate device sizing, assess patients for valve-in-valve procedures, and screen for adverse features or procedural contraindications...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

BACKGROUND: A comparison was made between the accuracy of and time saved by using novel automated software for pre-procedural computed tomography (CT) planning before transcatheter aortic valve implantation (TAVI) and manual methods. Preprocedural CT to assess aortic annulus dimensions and predict the optimal C-arm implant angle before TAVI can reduce complications related to incorrect prosthesis sizing and positioning. METHODS: A total of 61 consecutive patients underwent TAVI using either the SAPIEN XT or CoreValve prosthesis...

Surgical aortic valve replacement still represents the gold standard in patients with severe symptomatic aortic valve stenosis. In addition to conventional aortic valve replacement by mechanical or biological prostheses via a median sternotomy, novel approaches including minimally invasive strategies and new devices, such as so-called rapid deployment prostheses, are becoming increasingly more established. Autologous replacement strategies including the Ross and the Ozaki procedures have evolved into reliable options at selected centers of excellence...

Transcatheter aortic valve implantation/replacement (TAVI or TAVR) has been established as a first line therapy in patients with symptomatic severe aortic stenosis (AS) at high or prohibitive surgical risk and as an alternative in elderly patients with intermediate surgical risk. Since its first-in-human procedure in 2002, the past 15-years have shown rapid developments in TAVI technology with the introduction and further improvement of new transcatheter heart valves (THV). Areas covered: There are currently several THV systems available, based on balloon-expandable, self-expandable or other technologies...

REVIEW
Igor Volodarsky, Sarah Shimoni, Kobi George
Trans-catheter aortic valve implantation is a relatively novel procedure first performed in 2002, which has undergone rapid development since then. Nowadays, it is performed in many medical centers throughout the world. The main indication for the procedure is treatment of severe symptomatic aortic valve stenosis. At the outset, the procedure was indicated for very sick patients with prohibitive surgical risk. Nevertheless, broad employment of this procedure, rapid development of the medical equipment required for it, and improvement in the skill of the medical personnel involved in it, eventually led to its elevation to a different grade...

BACKGROUND: There is growing evidence from the literature that right anterior minithoracotomy aortic valve replacement (RAT-AVR) improves clinical outcome. However, increased cross clamp time is the strongest argument for surgeons not performing RAT-AVR. Rapid deployment aortic valve systems have the potential to decrease cross-clamp time and ease this procedure. We assessed clinical outcome of rapid deployment and conventional valves through RAT. METHODS: Sixty-eight patients (mean age 76 ± 6 years, 32% females) underwent RAT-AVR between 9/2013 and 7/2015...

We report the clinical case of a male patient who presented, after an aortic valve replacement with a rapid deployment bioprosthesis, a Heyde-like syndrome, secondary to a moderate aortic paravalvular leakage. All the digestive and hematologic investigations confirmed the diagnosis. A redo surgery to fill the paravalvular gap was accomplished and the postoperative course was uneventful, with a normalization of the biological parameters. To our knowledge, this is the first described case of such a complication with the new generation of sutureless bioprosthesis...
