Sutureless valve

Julia Götte, Wolfgang Hemmer, Detlef Roser, Markus Liebrich, Nicolas Doll
We report the case of a 83-year-old man who had undergone a full root replacement with a stentless bioprosthesis 15 years earlier. He was now diagnosed with severe aortic valve regurgitation secondary to leaflet degeneration, moderate mitral regurgitation, and single-vessel coronary artery disease. To reduce cross-clamp time and technical difficulties a sutureless aortic prosthesis was used. His surgery and postoperative course were uneventful. This is the first report of the successful use of a sutureless aortic valve prosthesis in a patient after bioprosthetic full root replacement who required additional mitral repair and coronary artery bypass surgery...

The recent literature on transcatheter aortic valve replacement (TAVR) is shedding new light on the perspective to extend this procedure to other lower risk-category of patients, leading in fact to a potential erosion of the current guidelines. Notwithstanding the warnings provided in the literature regarding the risk of severely impairing complications, unclear survival advantage and cost-inefficiency, many observational studies, especially performed in high-volume centers, support a general drive toward the recruitment of intermediate-low risk patients in the expectation of clinical advantages versus standard surgical replacement...

BACKGROUND: Sutureless self-expandable aortic bioprostheses rely on radial forces for stabilization, raising concern that these devices may increase the risk of postoperative conduction disease. The purpose of this study was to determine the incidence of conduction disorders after sutureless aortic valve replacement (AVR) with the Perceval S (Sorin Group, Saluggia, Italy) bioprosthesis. METHODS: Between June 2011 and March 2013, 108 consecutive patients underwent sutureless AVR with the Perceval S prosthesis...

Sutureless aortic bioprostheses (SAB) are increasingly being used to provide shorter cross-clamp time. Valve-in-valve transcatheter aortic valve replacement (VIV-A) is shown to be effective and safe in the vast majority of patients with degenerated bioprosthetics, yet its' use in SAB failure is infrequent. We present a case of balloon-expandable VIV-A in an 80-year-old woman who suffered severe symptomatic aortic regurgitation in a failed Perceval S 21-mm valve. Computed tomography scan demonstrated a deformed valve...

BACKGROUND We present a unique case of a 61-year-old female patient with homograft deterioration after redo surgery for prosthetic valve endocarditis with root abscess. CASE REPORT The first operation was performed for type A dissection with root, arch, and elephant trunk replacement of the thoracic aorta. The present re-redo surgery was performed as valve-in-valve with a sutureless aortic bioprosthesis. The postoperative course was uneventful and the patient was discharged on day 6. CONCLUSIONS The current case report demonstrates that sutureless bioprostheses are an attractive option for surgical valve-in-valve procedures, which can reduce morbidity and mortality...

Until now, to our knowledge no case of bioprosthetic valvular thrombosis after implantation of the sutureless Sorin Perceval valve has been reported. Although sutureless aortic valve replacement has become a powerful tool in our daily practice, recent guidelines from the European Society of Cardiology, the European Association for Cardio-Thoracic Surgery, the American College of Cardiology, and the American Heart Association do not give specific recommendations on postoperative anticoagulation therapy. We report the first case of valve dysfunction resulting from thrombosis 12 months after implantation with a possible link to postoperative cortisole therapy...

OBJECTIVE: Aortic valve replacement (AVR) in patients with a small aortic annulus is a challenging problem. The objective of this study was to compare 4 surgical approaches in terms of hemodynamics and perioperative outcomes. METHODS: A retrospective single-center study included 351 consecutive patients with a small aortic annulus (≤21 mm) who underwent aortic valve surgery between January 2007 and December 2014. Surgical techniques included standard AVR in 259 (74%) patients, aortic root enlargement in 20 (6%), implantation of a stentless bioprosthesis in 23 (6%), and sutureless AVR in 49 (13%)...

Thrombocytopenia occurring after surgical bioprosthetic valve implantation is a phenomenon that has been long investigated, and various explanations have been provided [Santarpino 2012a]. Our group has been addressing this topic over several years, extending back to the original description of this phenomenon in Freedom Solo (Sorin Group, Saluggia, Italy). However, we observed that this was a transitory and self-limited phenomenon without clinical consequence [Santarpino 2011; Santarpino 2012a]. Our center began implanting the Perceval aortic valve (Sorin Group, Saluggia, Italy) in 2010, and we have gained a vast experience in sutureless aortic valve replacement with Perceval, with more than 300 implants performed to date [Fischlein 2015]...

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...

OBJECTIVES: In high-risk patients with severe aortic stenosis, aortic valve replacement (AVR) with a sutureless Perceval prosthesis (SU-AVR) can be performed instead of conventional AVR or transcatheter aortic valve implantation. Little data are available regarding postoperative conduction disorders after SU-AVR. We aimed to determine the incidence and predictors of new-onset complete atrioventricular block (NO-AVB) requiring permanent cardiac stimulation following SU-AVR. METHODS: We studied consecutive patients who underwent SU-AVR between 2013 and 2015...

BACKGROUND: Aortic valve replacement has evolved recently with the development of the sutureless bioprosthesis. One such valve is the Perceval bioprosthesis, which is built by mounting leaflets of bovine pericardium to a thin stent; this approach has the potential to provide an excellent fluid dynamic performance. We undertook an in vitro study to compare the hydrodynamic performance of the sutureless bioprosthesis with two standard pericardial stented bioprostheses (Crown and Magna)...

BACKGROUND: Sutureless aortic valve prostheses have the potential of shortening surgical time, but if this results in improved clinical outcome remains to be determined. The aim of this study was to compare the outcome of patients undergoing conventional vs minimally invasive AVR, with either a stented or sutureless bioprosthesis. METHODS: From 2007 to 2015, 627 patients underwent elective isolated AVR and were divided into three groups: 206 patients who underwent sutureless-AVR via J- sternotomy (A) and patients who underwent stented-AVR via J- sternotomy (B, n=247) or full-sternotomy (C, n=174)...

Few experiences exist in minimally invasive cardiac surgery for the treatment of double-valve disease. We report our early experience in 69 patients, describing postoperative results. The introduction of sutureless aortic prostheses has implemented this treatment option, with a significant reduction of cardiopulmonary bypass and cross-clamp times.

BACKGROUND: In elderly high-risk surgical patients, sutureless aortic valve replacement (AVR) should be an alternative to standard AVR. The potential advantages of sutureless aortic prostheses include reducing cross-clamping and cardiopulmonary bypass (CPB) time and facilitating minimally invasive surgery and complex cardiac interventions, while maintaining satisfactory hemodynamic outcomes and low rates of paravalvular leakage. The current study reports our single-center experience regarding the early outcomes of sutureless aortic valve implantation...
