Cardiovascular diseases continue to be a major cause of mortality and morbidity in the world population. First open heart procedure was performed by Gibbon in 1953, since then many advancements have been introduced to the field of cardiac surgery. Minimally invasive techniques were introduced, which include minimally invasive coronary artery bypass grafting (CABG), off-pump technique, minimally invasive valve surgery or transcatheter techniques to implant stentless or sutureless valves. The hybrid strategy to address coronary disease combines catheterisation procedures with standard surgical techniques...

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...

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...

REVIEW
Ahmed Al-Adhami, Nawwar Al-Attar
Aortic valve replacement is no longer an operation that is approached solely through a median sternotomy. Recent advances in the fields of transcatheter valves have expanded the proportion of patients eligible for intervention. Comparisons between transcatheter valves and conventional surgery have shown non-inferiority of transcatheter valve implants in patients with a high or intermediate pre-operative predictive risk. With advances in our understanding of sutureless valves and their applicability to minimally invasive surgery, the invasiveness and trauma of surgery can be reduced with potential improvements in outcome...

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...

OBJECTIVES: In this study, the influence of aortic root distensibility on the haemodynamic parameters and valve kinematics of a bioprosthetic aortic valve was investigated in a controlled in vitro experiment. METHODS: An Edwards INTUITY Elite 21 mm sutureless aortic valve (Edwards Lifesciences, Irvine, CA, USA) was inserted in three transparent aortic root phantoms with different wall thicknesses (0.55, 0.85 and 1.50 mm) mimicking different physiological distensibilities...

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]...
