BACKGROUND: The study aim was to investigate the hemodynamic behavior over time and ease of implant and durability of the Sorin Pericarbon Freedom (SPF)® stentless pericardial aortic xenograft. METHODS: Between March 2003 and April 2010, a total of 251 consecutive, non-selected patients (mean age 70.1 years; range: 17-89 years; 17.1% aged >80 years) received a SPF bioprosthesis as an aortic valve substitute at the authors' institution. All implantations were performed by a single surgeon using a classical, double-line, subcoronary implant technique...

About 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule out measurement errors and treat hypertension. The second step is to distinguish pseudo-severe from true severe AS (TSAS). The third step is to select the optimal treatment modality at the right time. Regarding the second step, projected aortic valve area calculated using stress echocardiography is superior to traditional severity criteria (AVA < 1...

OBJECTIVES: The authors sought to investigate the prevalence, risk factors, and mid-term mortality in Asian patients with prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR). BACKGROUND: Little information is available on PPM after TAVR in Asian patients. METHODS: The authors included 1,558 patients enrolled in the OCEAN-TAVI (Optimized transCathEter vAlvular iNtervention) Japanese multicenter registry from October 2013 to July 2016 after excluding patients who died following TAVR before discharge...

The original monograph on valvular prostheses in Surgical Technology International was published in 1993. It represents a milestone and a reference point for critically organizing information on a complex and rapidly evolving topic. The last update was published in 2010. Since then, there have been significant developments regarding both "traditional" surgical prosthesis and valves for transcatheter implantation. Both bioprostheses and mechanical prostheses continue to evolve with respect to both their design and materials to further optimize hemodynamics and prevent a patient-prosthesis mismatch...

Background: New models of aortic bioprostheses have proven excellent early haemodynamic profile, but their mid and long-term performance warrants further systematic assessment. The aim of this study is to report clinical and haemodynamic performance of St. Jude Medical Trifecta bioprosthesis during 5 years of implantation. Methods: We performed a single centre, retrospective, observational and descriptive study including all 556 individuals who underwent aortic valve replacement (AVR) with the Trifecta bioprosthesis (between July of 2011 and June of 2016)...

Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) has been established as a safe and effective means of treating failed surgical bioprosthetic valves (BPVs) in patients at high risk for complications related to reoperation. Patients who undergo VIV TAVR are at risk of patient-prosthesis mismatch, as the transcatheter heart valve (THV) is implanted within the ring of the existing BPV, limiting full expansion and reducing the maximum achievable effective orifice area of the THV. Importantly, patient-prosthesis mismatch and high residual transvalvular gradients are associated with reduced survival following VIV TAVR...

AIMS: To assess the predictive value of simulation based on 3D-printed models before left atrial appendage occlusion (LAAO) for peri-device leaks (PDL) and the impact on procedural outcomes compared to conventional imaging. METHODS AND RESULTS: 76 patients referred for LAAO with double disc device underwent construction of a 3D-printed LA model using flexible photopolymer resin. An implant simulation was performed retrospectively in Group 1 (55 patients), blinded to implanted device size, and prospectively in Group 2 (21 patients)...

OBJECTIVE: The goals of rapid-deployment aortic valve replacement include facilitation of minimally invasive surgery and reduced aortic crossclamp time. We report the short-term outcomes of a series of 493 patients undergoing rapid-deployment aortic valve replacement with the EDWARDS INTUITY valve system (Edwards Lifesciences, LLC, Irvine, Calif). METHODS: Assessing Standard oF Care and Clinical Outcomes UsiNg the EDWARDS INTUITY VAlve SysTem in a European multI-center, Active, pOst-market surveillaNce Study was a prospective, multicenter (n = 26) European registry designed to evaluate the safety and performance of the valve system...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether patient-prosthesis mismatch (PPM) has a negative impact on patients undergoing mitral valve replacement in terms of postoperative mortality, incidence of postoperative pulmonary hypertension (PH) and higher transmitral gradients. Altogether 103 papers were found using the reported search, 18 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated...

INTRODUCTION: Three-dimensional (3D) prototyping is a novel technology which can be used to plan and guide complex procedures such as transcatheter mitral valve replacement (TMVR). METHODS: Eight patients with severe mitral annular calcification (MAC) underwent TMVR. 3D digital models with digital balloon expandable valves were created from pre-procedure CT scans using dedicated software. Five models were printed. These models were used to assess prosthesis sizing, anchoring, expansion, paravalvular gaps, left ventricular outflow tract (LVOT) obstruction, and other potential procedure pitfalls...

OBJECTIVE: We aimed to analyse the incidence of prosthesis-patient mismatch (PPM) and elevated gradients after aortic valve in valve (ViV), and to evaluate predictors and associations with clinical outcomes of this adverse event. METHODS: A total of 910 aortic ViV patients were investigated. Elevated residual gradients were defined as ≥20 mm Hg. PPM was identified based on the indexed effective orifice area (EOA), measured by echocardiography, and patient body mass index (BMI)...

OBJECTIVES: The aim of this study was to determine whether the association of small label size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) implantation is, at least in part, related to pre-existing prosthesis-patient mismatch (PPM) (i.e., a bioprosthesis that is too small in relation to body size). BACKGROUND: Transcatheter ViV implantation is an alternative for the treatment of patients with degenerated bioprostheses...

Controversy still surrounds the optimal biological valve substitute for aortic valve replacement. In light of the current literature, we review advantages and optimal indications of stentless compared to stented aortic bio-prostheses. Recent meta-analyses, prospective randomized controlled trials and retrospective studies comparing the most frequently used stentless and stented aortic bio-prostheses were analyzed. In the present review, the types and implantation techniques of the bio-prosthesis that are seldom taken into account by most studies and reviews were integrated in the interpretation of the relevant reports...
