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...

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...

BACKGROUND: Alternative access for thoracic endovascular aortic repair (TEVAR) has been explored for patients with unsuitable femoral and iliac access, but few cases of transapical access have been described. We report our experience with transapical access for various aortic pathologies. METHODS: We reviewed 6 cases undergoing transapical access for endovascular repair of thoracic aortic pathology between December 2013 and August 2015. Five patients had an aortic arch aneurysm and 1 patient presented with Stanford type A subacute aortic dissection...

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...

INTRODUCTION: Rapid deployment valves (RDV) represent a newly introduced approach to aortic valve replacement which facilitates surgical implantation and minimally invasive techniques, shortens surgical times and shows excellent haemodynamic performance. However, evidence on their safety, efficacy and potential complications is mostly fitted with small-volume and retrospective studies. Moreover, no current guidelines exist. To improve our knowledge on this technology, The Rapid Deployment Aortic Replacement (RADAR) Registry will be established across Spain with the aim of assessing RDV outcomes in the real-world setting...

We report a case of rescue bypass cannulation of the ventricular apex during a transapical transcatheter aortic valve implantation procedure in a patient with peripheral vascular disease not amenable to peripheral cannulation. Following rapid pacing and deployment of the transcatheter valve, cardiac function did not recover. The arterial cannula was inserted through the left ventricular apex, at the site of the transapical sheath, and advanced across the prosthetic valve, allowing for rapid initiation of cardiopulmonary bypass...

Recent studies report a reproducible reduction of myocardial ischemic and cardiopulmonary bypass times along with excellent hemodynamics and low rates of paravalvular leakage for rapid-deployment valves. A 68-year-old female patient with aortic stenosis and a mechanical mitral valve which was implanted in 2006 received rapid-deployment aortic valve replacement. The procedure could be performed with a cross-clamp time of 45 minutes and a cardiopulmonary bypass time of 60 minutes. Postoperative course was uncomplicated and the patient was discharged to the referring hospital on postoperative day 8...

Sutureless and rapid-deployment aortic bioprostheses represent an emerging and promising technology for the treatment of aortic valve stenosis. Unlike traditional aortic bioprostheses, these devices are not hand-sewn, thus allowing a significant reduction in operative times, while facilitating minimally invasive surgery and complex cardiac interventions. Sutureless aortic valve replacement represents a less invasive treatment option and an excellent alternative to conventional aortic valve replacement in elderly and higher risk patients...

Surgical aortic valve replacement is the most common procedure of choice for the treatment of severe aortic stenosis. Bioprosthetic valves are traditionally sewed-in the aortic root by means of pledget-armed sutures during open-heart surgery. Recently, novel bioprostheses which include a stent-based anchoring system have been introduced to allow rapid implantation, therefore reducing the duration and invasiveness of the intervention. Different effects on the hemodynamics were clinically reported associated with the two technologies...
