BACKGROUND: Suture-less and trans-catheter aortic valve implantation are increasingly adopted methods to treat high risk patients with severe aortic valve stenosis. We conducted a systematic review and meta-analysis to compare the clinical outcomes between the two recent methods to treat aortic valve disease. METHODS: We systematically searched multiple databases (January 2000-October 2016) to identify original studies comparing clinical outcome between suture-less (SU-AVR) and trans-catheter aortic valve implantation (TAVI)...

OBJECTIVES: To evaluate the feasibility of fully percutaneous closure using a novel collagen-based vascular closure device after transfemoral aortic valve replacement (TAVR). BACKGROUND: TAVR is utilized increasingly for the treatment of severe symptomatic aortic stenosis. Vascular complications related to access and closure dominate the adverse event profile of the procedure despite progressively reducing arteriotomy caliber. The advent of a novel collagen-based device (MANTATM ) and preliminary data suggest this could be used as a routine percutaneous closure device...

Aortic valve replacement through minimally invasive access is increasing. These procedures have several advantages over conventional sternotomy including decreased intensive care unit and hospital length of stay and decreased ventilation time. The right anterior mini-thoracotomy (RAM) approach is potentially attractive in that it completely spares the sternum leading to improved cosmesis, reduced blood loss, and improved patient satisfaction. However, this approach is underutilized due to anticipated technical challenges including difficulty with visualization and annular suture placement...

Aortic root replacement is typically performed through a median sternotomy. The right anterior mini-thoracotomy approach has been shown to decrease hospital length of stay in aortic valve surgery when compared to sternotomy. This approach is rare in ascending aortic surgery due to technical challenges which include exposure and annular suture placement. Automated suturing technology is now available to facilitate the placement of annular sutures. The use of a camera greatly enhances visualization of the aortic root...

We present a modified bicuspid aortic valve reimplantation operation using a unique technique of second line, continuous suturing during implantation of the aortic valve scallop to the prosthesis that mimics stentless, minicylinder implantation.  The feasibility of bicuspid aortic valve repair with associated aortic root management has been demonstrated. However, this repair seems to be less durable than tricuspid aortic valve repair, and this may be partly because of the connective tissue disorders that are an inherent feature of bicuspid aortic valve disease...

BACKGROUND: To determine the value of aortic valve repair rather than replacement for valve dysfunction, we assessed late outcomes of various repair techniques in the contemporary era. METHODS: From January 2001 to January 2011, aortic valve repair was planned in 1,124 patients. Techniques involved commissural figure-of-8 suspension sutures (n = 63 [6.2%]), cusp repair with commissuroplasty (n = 481 [48%]), debridement (n = 174 [17%]), free-margin plication (n = 271 [27%]) or resection (n = 75) or both, or annulus repair with resuspension (n = 230 [23%]), root reimplantation (n = 252 [25%]), or remodeling (n = 35 [3...

OBJECTIVE: The lack of annular stabilization is the drawback of aortic root remodeling, and recently the addition of annuloplasty has been proposed. Limited data, however, exist on late annular size after remodeling. We studied annular size over time. METHODS: In 241 patients (53 ± 16 years) annular size was determined preoperatively (T0), before discharge (T1), and at least 2 years after remodeling (T2, 54 ± 27 months) with (n = 52) or without external suture annuloplasty...

BACKGROUND: Surgical aortic valve replacement (SAVR) is the treatment of choice in severe symptomatic aortic valve disease. New techniques and prostheses have been recently developed to facilitate the procedure and reduce aortic cross-clamp time (AOx). The aim of this study was to analyse the different procedural steps in order to identify the most time-consuming part during aortic clamping time and to compare impact of experience on procedural aspects. METHODS: AOx during SAVR was divided into five consecutive steps...

In patients with small aortic roots who need an aortic valve replacement with biological valve substitutes, the implantation of the stented pericardial valve might not meet the functional needs. The implantation of a too-small stented pericardial valve, leading to an effective orifice area indexed to a body surface area less than 0.85 cm(2)/m(2), is regarded as prosthesis-patient mismatch (PPM). A PPM negatively affects the regression of left ventricular hypertrophy and thus the normalization of left ventricular function and the alleviation of symptoms...

We report the case of severe aortic regurgitation 8 months after implantation of a 25-mm sutureless pericardial aortic valve prosthesis. On echocardiography, the regurgitation was suspected to be paravalvular. The sutureless prosthesis had been implanted using an automatic knot fastener device, which renders the suture tails less pliable because of the metal clip that is crimped around the suture. The patient was reoperated, a paravalvular leak was not observed. The sutureless prosthesis was explanted and a conventional biologic valve prosthesis was implanted instead...

AIMS: In the current study we assess the impact of two different access-site suture-mediated closure devices (SMCD), ProGlide and Prostar, on vascular and bleeding complications after transfemoral transcatheter aortic valve implantation (TAVI), as well as on long-term mortality. METHODS AND RESULTS: From 2008 to 2013, 1,022 patients underwent transfemoral TAVI in two German centres using ProGlide (n=506) and Prostar (n=516) SMCD to close the access site. The primary outcome was the incidence of peri-TAVI major vascular complications according to Valve Academic Research Consortium-2 (VARC-2) definitions...

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: Prostheses attachment is critical in aortic valve replacement surgery, yet reliable prosthetic security remains a challenge. Accurate techniques to analyze prosthetic fixation pressures may enable the use of fewer sutures while reducing the risk of paravalvular leaks (PVL). METHODS: Customized digital thin film pressure transducers were sutured between aortic annulus models and 21-mm bioprosthetic valves with 15 × 4-mm, 12 × 4-mm, or 9 × 6-mm-wide pledgeted mattress sutures...

Sutureless aortic valve implantation has emerged as an innovative alternative for treatment of aortic stenosis. By avoiding the placement of sutures, this approach aims to improve surgical outcomes by facilitating less traumatic minimally invasive approaches and reducing cross-clamp and cardiopulmonary bypass duration. However, the absence of sutures may have detrimental effects after sutureless interventions, including paravalvular leakages, valve dislocation, and stent-infolding. Transcatheter aortic valve-in-valve implantation (A-ViV) is emerging as a valuable procedure in patients with dysfunctioning biological aortic valves who are deemed inoperable with conventional surgery...

Percutaneous heart valve replacement is gaining popularity, as more positive reports of satisfactory early clinical experiences are published. However this technique is mostly used for the replacement of pulmonary and aortic valves and less often for the repair and replacement of atrioventricular valves mainly due to their anatomical complexity. While the challenges posed by the complexity of the mitral annulus anatomy cannot be mitigated, it is possible to design mitral stents that could offer good anchorage and support to the valve prosthesis...

BACKGROUND: Robotic mitral valve repair has been successfully performed since the late 1990s, but concomitant robotic tricuspid repair has not yet been widely adopted. We report our first 5 years' experience with concomitant robotic mitral-tricuspid valve repair. METHODS: Records were reviewed for all patients who underwent concomitant robotic mitral-tricuspid valve repair in a single practice. Cardiopulmonary bypass was performed with femoral cannulation, antegrade and retrograde cardioplegia, and aortic cross-clamping by balloon occlusion...
