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...

OBJECTIVES: To determine which procedure, aortic valve replacement (AVR) with a sutureless or rapid-deployment prosthesis (SL-AVR) or transcatheter aortic valve implantation (TAVI), achieves better perioperative survival for severe aortic stenosis (AS), we conducted direct-comparison meta-analyses (DC-MAs) and an adjusted indirect-comparison meta-analysis (IDC-MA). METHODS: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials through April 2016...

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) in patients with degenerated bioprosthetic aortic valve has been successfully performed as an alternative to surgery. We describe our initial experience of valve-in-valve TAVI in five patients, using new generation Edwards Sapien 3 transcatheter heart valves implanted into degenerated 19 mm bioprosthetic valves. 20-mm Edwards S3 valves were offered for compassionate use. All patients had significant aortic valve stenosis. METHODS AND RESULTS: The main vascular access was achieved and pre-closed with two Proglide closure devices in one patient and Prostar closure devices in four patients...

Homograft implantation in the aortic position was a common approach for full root aortic surgical procedures in the early 2000s. Reintervention after degeneration of such homografts remains a challenge. We report two cases of successful implantation of the Edwards Intuity Elite rapid deployment valve into patients with degeneration of existing aortic homograft implants leading to severe aortic regurgitation.

The treatment of both aortic and now mitral valvular disease has been transformed through transcatheter valvular interventions. TAVR has rapidly become the treatment of choice for symptomatic severe aortic stenosis in both high, and now intermediate-risk patients. Building upon this success the last two years have seen the clinical introduction of transcatheter mitral valve replacement (TMVR), with a number of devices being utilised in first-in-man and feasibility studies. These experiences have helped determine the anatomical requirements and specifications that enable successful device deployment and avoidance of complications...

Aortic valve stenosis is the most common valve disease in the western world. Over the past few years the number of aortic valve replacement (AVR) interventions has increased with outcomes that have been improved despite increasing age of patients and increasing burden of comorbidities. However, despite such excellent results and its well-established position, conventional AVR has undergone great development over the previous two decades. Such progress, by way of less invasive incisions and use of new technologies, including transcatheter aortic valve implantation and sutureless valve prostheses, is intended to reduce the traumatic impact of the surgical procedure, thus fulfilling lower risk patients' expectations on the one hand, and extending the operability toward increasingly high-risk patients on the other...

OBJECTIVE: The recent development of the EDWARDS INTUITY Elite™ (EIE) valve system enables the rapid deployment of a prosthetic surgical heart valve in an aortic valve replacement (AVR) procedure via both the minimally invasive (MISAVR) and conventional (CAVR) approaches. In order to understand its economic value, this study performed a cost evaluation of the EIE valve system used in a MIS rapid-deployment approach (MIS-RDAVR) vs MISAVR and CAVR, respectively, compared to standard prosthetic aortic valves...

BACKGROUND: The use of rapid-deployment aortic valve replacement (RD-AVR) has burgeoned in recent years. There are few studies comparing RD-AVR to conventional aortic valve replacement (cAVR) and no studies where both were inserted via full sternotomy. As such, we reviewed our experience and compared the two approaches. METHODS: From 2008 to 2015, 597 patients underwent isolated aortic valve replacement ± coronary artery bypass grafting (CABG) at a single centre...

Transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis is a less invasive alternative to surgical aortic valve replacement. Despite this, careful anesthetic management, especially strict control of blood pressure and fluid management, is necessary. During TAVI, normalization of left ventricular afterload due to aortic balloon valvuloplasty and prosthetic valve deployment is expected to result in rapid improvement of systolic function and consequent improvement in diastolic function...

Transaortic transcatheter aortic valve replacement performed through a right anterolateral minithoracotomy at the second intercostal space is a safe and standardized minimally invasive procedure carrying important clinical advantages for the patient, in particular, no damage to the ventricular apex, preservation of the diseased peripheral arteries and no cross of the aortic arch with the delivery system, meaning a lower risk of calcium dislodgement and neurological complications. Using the third-generation, balloon-expandable Edwards Sapien™ 3 transcatheter heart valve and the Certitude™ delivery system, the transaortic procedure is easily performed under fluoroscopic and echocardiographic guidance...

Transcatheter aortic valve implantation (T-AVI) has been established as an alternative to conventional aortic valve replacement. The number of procedures is steadily rising and has reached comparable implant rates to conventional aortic valve replacement. The success of T-AVI is easily explained by their true minimally invasive nature, ease of use, and excellent hemodynamics. Whilst their use was initially limited to high-risk patients, current trends show that more and more intermediate-risk patients are now treated with theses prostheses...

OBJECTIVES: Sutureless and rapid-deployment valves were recently introduced into clinical practice. The Edwards INTUITY valve system is a combination of the Edwards Magna pericardial valve and a subvalvular stent-frame to enable rapid deployment. We performed a parallel cohort study for comparison of the two valve types. METHODS: All patients receiving either an Edwards Magna Ease valve or an Edwards INTUITY valve system due to aortic stenosis from May 2010 until July 2014 were included...

Cerebral oxygen saturation (rSO2) is a non-invasive monitor used to monitor cerebral oxygen balance and perfusion. Decreases in rSO2 >20 % from baseline have been associated with cerebral ischemia and increased perioperative morbidity. During transcatheter aortic valve replacement (TAVR), hemodynamic manipulation with ventricular pacing up to 180 beats per minute is necessary for valve deployment. The magnitude and duration of rSO2 change during this manipulation is unclear. In this small case series, changes in rSO2 in patients undergoing TAVR are investigated...

OBJECTIVES: Aortic valve replacement (AVR) via minimally invasive surgery (MIS) may provide clinical benefits in patients with aortic valve disease. A new class of bioprosthetic valves that enable rapid deployment AVR (RDAVR) may facilitate MIS. We here report the 1-year results of a randomized, multicentre trial comparing the outcomes for MIS-RDAVR with those for conventional AVR via full sternotomy (FS) with a commercially available stented aortic bioprosthesis. METHODS: A total of 100 patients with aortic stenosis were enrolled in a prospective, multicentre, randomized comparison trial (CADENCE-MIS)...
