This is a report of the first Brazilian experience with the Perceval sutureless aortic prosthesis in two patients with severe aortic stenosis. Transesophageal echocardiography was used during the procedure. The aortotomy was performed 1 cm above the sinotubular junction, followed by leaflets removal and decalcification. Correct valve size was selected, device released and an accommodation balloon used. The cardiopulmonary bypass times were 47 and 38 min and the cross-clamp times were 38 and 30 min. There was a significant decrease in mean gradients (41 and 75 mmHg preoperatively; 7 and 8 mmHg postoperatively)...

Aortic valve replacement with a Perceval sutureless bioprosthesis is a viable rescue option for a failed aortic stentless prosthesis. However, a dilated sinotubular junction and ascending aorta are reported as a contraindication for this technique. We describe an aortic sutureless valve implantation in a patient with a dilated ascending aorta and small aortic root after Dacron graft replacement of the ascending aorta in a failed aortic stentless bioprosthesis.

OBJECTIVE: In this paper, we present an endoscopic expandable sizer conceived to allow thoracoscopic aortic valve replacement with a sutureless prosthesis using a dynamic sizing of the aortic annulus. METHODS: Ten aortic torsos were prepared using a five-trocar thoracoscopic setting. Once the aortotomy was performed and the aortic valve leaflets removed, the technical feasibility of the endoscopic sizing (introduction into the trocar, expansion into the aortic annulus, determination of the valve size, and retraction) with the device was assessed...

AIMS: The aim was to determine the best functional position of a transcatheter heart valve (THV) implanted as a valve-in-valve (ViV) procedure in small rapid deployment valves (RDV) in an in vitro model. METHODS AND RESULTS: A 21mm Perceval™, Enable™ or INTUITY™ RDV was mounted into a pulse duplicator and a 23mm balloon-expandable or a self-expanding THV was deployed (valve-in-valve) in two different positions. Under physiological hydrodynamic conditions, performance of the THV was characterized by mean transvalvular pressure gradient (MPG), effective orifice area (EOA) and regurgitation volume (RV)...

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...

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...

Totally endoscopic cardiac operations for coronary procedures and atrial septal defect repair have demonstrated improved quality of life, but they have required longer cross-clamp times compared with open operations. Although transcatheter valve implantation remains appropriate for inoperable patients, the totally endoscopic approach could be an effective treatment for lower risk patients, including complete removal of the stenotic aortic valve, while minimizing surgical chest wall trauma, and providing excellent early quality of life...

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]...

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)...

OBJECTIVES: We examined the Sorin Perceval S artificial biological valve implantation techniques, and present the initial experiences in our unit. METHODS: In the last 1.5 years, 27 patients had been implanted with Sorin Perceval S biological arteficial valve due to aortic valve disease. The device was mainly used in high-risk patients, in reoperative circumstances, in cases of calcified aortic root, and in elderly patients. RESULTS: The valve implantation time, aortic cross clamp time is shorter, but the risk of the operation cannot be eliminated entirely, because of the high risk patients' severe comorbidities...

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...

Aortic root replacement with porcine xenograft is a valuable treatment option in acute aortic dissection, but conduits are often prone to degeneration. Reoperation is still associated with high operative mortality, and it usually requires root removal and repetition of the Bentall procedure, or a less radical option limited to valve replacement. We describe two cases of Freestyle root degeneration in patients with chronic aortic dissection, in whom we performed a valve-in-valve procedure with the Perceval S prosthesis (Sorin Group, Saluggia, Italy)...

Aortic valve replacement with concomitant mitral valve surgery in the presence of severe aortic root calcification is technically difficult, with long cardiopulmonary bypass and aortic cross-clamp times. We performed sutureless aortic valve replacement and mitral valve annuloplasty in a 68-year-old man who had severe aortic stenosis and moderate-to-severe mitral regurgitation. Intraoperatively, we found severe calcification of the aortic root. We approached the aortic valve through a transverse aortotomy, performed in a higher position than usual, and we replaced the valve with a Sorin Perceval S sutureless prosthesis...
