Bioprosthetic aortic valves have been used with increasing frequency over the past two decades, often in relatively young patients who may eventually require aortic valve re-operations due to degeneration of the bioprosthesis. Growing experience with minimally invasive aortic valve replacement has prompted surgeons to use minimally invasive approaches also with redo operations for replacement of the aortic valve.  This tutorial describes the operative steps for a minimally invasive redo replacement of the aortic valve through an upper ministernotomy...

AIM: To report our initial experience with lens-sparing vitrectomy for stage 4 retinopathy of prematurity using the 27-gauge (G) system. METHODS: This retrospective case series involved nine eyes of five babies with active stage 4 ROP, who underwent 27-G lens-sparing vitrectomy. Surgery was done using 27-G valved cannulas and sclerotomies were made 1.5 mm from the limbus. Bilateral sequential vitrectomy was done in eight eyes. RESULTS: At one-year follow-up, anatomical outcome was favourable in all nine (100%) eyes...

Sutureless aortic valves are increasingly used for aortic valve replacement (AVR) with excellent outcomes. Implantation requires device expansion in a subannular position within the native aortic root. We report a patient with severe aortic stenosis who received a Perceval sutureless AVR (LivaNova, London, United Kingdom), resulting in a competent prosthesis with an absence of paravalvular leak and aortic regurgitation. However, this implantation resulted in the exacerbation of mitral regurgitation. The sutureless valve required explantation, and a traditional sutured valve was subsequently implanted, which returned the mitral regurgitation to baseline...

PURPOSE: Rapid deployment/sutureless aortic valve replacement is aimed at minimizing the invasiveness of surgical aortic valve replacement. We describe the implantation techniques of a new rapid deployment aortic valve, focusing on its unique and challenging features. DESCRIPTION: The EDWARDS INTUITY Elite aortic valve (Edwards Lifesciences, Irvine, CA) represents a hybrid between the surgical PERIMOUNT Magna Ease (Edwards Lifesciences) pericardial valve, but with advanced features of the percutaneous SAPIEN valve system (Edwards Lifesciences)...

BACKGROUND: Aortic stenosis is the most common valvular disease and has a dismal prognosis without surgical treatment. The aim of this meta-analysis was to quantitatively assess the comparative effectiveness of the Perceval (LivaNova) valve versus conventional aortic bioprostheses. METHODS AND RESULTS: A total of 6 comparative studies were identified, including 639 and 760 patients who underwent, respectively, aortic valve replacement with the Perceval sutureless valve (P group) and with a conventional bioprosthesis (C group)...

INTRODUCTION: Traditional and transcatheter surgical treatments of severe aortic valve stenosis (SAVS) are increasing in parallel with the improved life expectancy. Recent randomised controlled trials (RCTs) reported comparable or non-inferior mortality with transcatheter treatments compared with traditional surgery. However, RCTs have the limitation of being a mirror of the predefined inclusion/exclusion criteria, without reflecting the 'real clinical world'. Technological improvements have recently allowed the development of minimally invasive surgical accesses and the use of sutureless valves, but their impact on the clinical scenario is difficult to assess because of the monocentric design of published studies and limited sample size...

Background: Sutureless aortic valve replacement (SU-AVR) has been developed as an alternative surgical treatment for patients with symptomatic severe aortic stenosis (AS). The aim of this study was to evaluate the clinical outcomes of SU-AVR through an assessment of hemodynamic performance and safety. Methods: From December 2014 to June 2016, a total of 12 consecutive patients with severe AS underwent SU-AVR. The endpoints were overall survival and valve-related complications (paravalvular leakage, valve thrombosis, migration, endocarditis, and permanent pacemaker implantation)...

BACKGROUND: Significant underexpansion or distortion of valved stents may be associated with altered leaflet function, leading to increased transprosthetic gradients and, possibly, early structural degeneration. We investigated the relationship between a computed tomography (CT) measure of the degree of oversizing and the early haemodynamic and clinical outcomes in patients undergoing aortic valve replacement with the Perceval sutureless aortic valve. METHODS: The degree of oversizing of the implanted prosthesis was calculated as the ratio between the patients' aortic annulus cross-sectional area (CSA) and the ex-vivo CSA of the implanted prosthesis in 151 perceval patients that had a preoperative cardiac CT...

Quadricuspid aortic valve (QAV) is a rare occurrence, usually presenting with insufficiency rather than stenosis. We report a case of aortic valve replacement in a septuagenarian with a stenotic QAV, achieving a good result with a Sorin Perceval sutureless bioprosthesis. We emphasize the particular technique of implantation and possible pitfalls. Sutureless bioprosthetic valves present a feasible option for aortic valve replacement in patients with uncommon valve morphologies, aiming to reduce operative time...

Because of its favourable haemodynamic characteristics and easy implantability, Mitroflow aortic valve bioprosthesis has been the valve of choice for many surgeons in patients with small aortic annulus. Disappointingly, early structural valve deterioration and high transvalvular gradients have been reported mostly in older patients with small prostheses. Reimplanting a new stented prosthesis sutured in a narrow and damaged annulus is technically challenging and demanding mainly in high-risk patients. Valve-in-valve transcatheter aortic valve implantation has been proposed as a viable option; however, it presents significant limitations because of residual high transprosthetic pressure gradients and risk of coronary occlusion...

Despite the limited clinical relevance of thrombocytopenia after bioprosthetic aortic valve replacement (AVR), the postoperative depletion of platelet count continues to attract the attention of many authors. The development of thrombocytopenia has been evaluated either in patients receiving a sutureless bioprosthesis (1,2) or in those undergoing transcatheter aortic valve implantation, where cardiopulmonary bypass bears little or no relation to this phenomenon (3). Recently, Sánchez et al. (1) have published their findings on this topic, but their limited experience with the devices used makes their study of doubtful interest...

Sutureless aortic bioprostheses (SAB) provide shorter aortic cross-clamp time and cardiopulmonary bypass duration compared to conventional aortic valve replacement. Similarly to other bioprostheses, reintervention may become necessary in some cases because of long-term structural degeneration of the valve. Valve-in-valve (ViV) transcatheter aortic valve replacement may represent an effective and safe alternative to aortic valve replacement in patients with degenerated bioprostheses who carry a high risk for reintervention...

We describe three patients with severe aortic regurgitation after aortic root replacement using the Medtronic Freestyle® bioprosthesis. In two cases, the indication was endocarditis. The third case showed rupture of the right coronary cusp. To achieve fewer complications, lower operative risk and save operative and cross-clamp times, implantation of a sutureless bioprosthesis in a valve-in-valve manner was performed. In two cases, a Perceval bioprosthesis and in the other case, a 3f-Enable bioprosthesis were used...

BACKGROUND: Aim of this study was to assess the potential differences in respecting the principles of goal-directed perfusion between aortic valve replacement with sutureless vs conventional stented bioprostheses. METHODS: Data from 94 consecutive patients undergoing aortic valve replacement with Perceval sutureless valve, with or without concomitant CABG, were compared to a contemporary cohort of 116 patients receiving conventional stented bioprostheses. Propensity score matching was used to reduce selection bias...
