perimount Valve

OBJECTIVES: Thrombocytopenia following Perceval aortic valve replacement has been described previously with variable outcome. Studies have lacked a robust analysis of platelet fluctuation and factors affecting it. We aimed to statistically describe the trend in thrombocyte variability as compared with conventional aortic valve replacement, and to assess predictors as well as impact on associated outcomes. METHODS: One hundred consecutive patients with first-time Perceval were retrospectively compared to 219 patients after Perimount Magna Ease valve replacement...

BACKGROUND: Sutureless valves are widely used in aortic valve replacement surgery, with Perceval valves and Intuity valves being particularly prominent. However, concerns have been raised about postoperative thrombocytopenia with Perceval valves (Corcym, UK). We conducted a comparative analysis with the Intuity valve (Edwards Lifesciences, USA), and assessed how thrombocytopenia affected patient and transfusion outcomes. METHODS: Among 595 patients who underwent aortic valve replacement from June 2016 to March 2023, sutureless valves were used in 53 (Perceval: n=23; Intuity: n=30)...

Since the introduction of transcatheter aortic valve (AV) implantation as a viable option, surgical bioprosthetic AVs have recently started incorporating shorter struts considering future valve-in-valve procedures. However, the effect of leaflet coaptation geometry on the longevity of these valves remains unexplored. To address this gap, we performed a finite element analysis on bioprosthetic AVs with varying strut heights using a two-way fluid-structure interaction method. To establish a baseline, we used a standard height based on a rendered platform image of the CE PERIMOUNT Magna Ease valve from Edward Lifesciences in Irvine, CA...

This study examines a complex scenario of structural valve degeneration (SVD) in a high surgical-risk patient with a previously implanted 25 mm Carpentier-Edwards (CE) Perimount Magna Ease 3300 (Irvine, CA: Edwards Lifesciences) surgical bioprosthetic valve (SAV), the patient presented with both paravalvular leak (PVL) and central prosthetic valve insufficiency (PVI). The patient was considered for a transaortic valve-in-valve (ViV) intervention with a self-expanding 29 mm Evolut R valve (Minneapolis, MN: Medtronic)...

BACKGROUND: Rapid-deployment aortic valve replacement (RDAVR) is an alternative to conventional AVR (cAVR) for aortic stenosis. Benefits include a reduction in operative times, facilitation of minimal access surgery and superior haemodynamics compared to conventional valves. However, further evidence is required to inform guidelines, preferably in the form of propensity-matched studies that include mid-term follow-up data. METHODS: This was a single-centre, retrospective, propensity-matched cohort study comparing the Perceval and conventional Perimount Magna Ease valve for short- and mid-term clinical parameters and size-matched mid-term echocardiographic parameters (n = 102 in both groups) from 2014 to 2020...

OBJECTIVES: While current data show a clear trend towards the use of bioprosthetic valves during aortic valve replacement (AVR), durability of bioprosthetic valves remains the most important concern. We conducted a 1st systematic review of all available evidence that analysed early and mid-term outcomes after AVR using the Inspiris RESILIA™ bioprosthesis. METHODS: A systematic literature search was performed to identify all relevant studies evaluating early and mid-term outcomes after AVR using the Inspiris RESILIA bioprosthesis and including at least 20 patients with no restriction on the publication date...

A 14-year-old girl was scheduled for pulmonary valve replacement. A computed tomography scan showed an enlarged cardiac silhouette with an aneurysmal pulmonary artery. A less-invasive approach through the left axilla with peripheral cannulation was selected. The patient was draped in the decubitus position, with a roll under the left shoulder and the left arm over the head. The anatomical landmarks were the left nipple and the tip of the scapula. A 5-cm vertical incision in the mid-axillary line was performed, and the thorax was entered through the fourth intercostal space...

OBJECTIVES: The population of candidates to surgical aortic valve replacement (SAVR) is evolving. The Perimount Magna Ease© bioprosthesis has been introduced relatively recently in the practice. We aimed at evaluating its long-term results. METHODS: Single-center cohort of 1,016 consecutive SAVRs with the Magna Ease© valve (2008-2014), all-comers population. Prospective collection of in-hospital data, systematic clinical and echocardiographic follow-up...

OBJECTIVE: This study evaluated the very long-term results of the Carpentier-Edwards pericardial bioprosthesis in the mitral position, with particular attention to structural valve deterioration based on echocardiographic criteria. METHODS: From 1984 to 2016, 648 patients (mean age 68.8 years; 53.9% female) underwent mitral valve replacement using the Carpentier-Edwards PERIMOUNT pericardial bioprosthesis. Multiple valve replacements were excluded. Clinical, operative, and follow-up data were prospectively recorded...

PURPOSE: Bioprosthetic Heart Valves (BHVs) are widely used in clinical practice, showing promising outcomes. Computational modeling offers a valuable tool for quantitatively characterizing BHVs. To ensure the accuracy of computational models, it is crucial to consider precise leaflet properties, including mechanical properties and density. Bovine pericardium (BP) serves as a common material for BHV leaflets. Previous computational studies often assume BP density to approximate that of water or blood...

BACKGROUND: Edwards Intuity is designed for rapid deployment based on the structure of Magna Ease. This study was conducted to compare early hemodynamic performance between the two valves. METHODS: Patients who underwent aortic valve replacement (AVR) using Edwards Intuity or Carpentier-Edwards PERIMOUNT Magna Ease in our institution from June 2016 to July 2021 were enrolled. Intuity valve was used in 215 patients, and Magna Ease valve was used in 198 patients, respectively...

BACKGROUND: Structural valve dysfunction in bioprosthetic heart valves necessitates redo replacement procedure that are associated with high mortality and morbidity. The transcatheter valve-in-valve (VIV) approach has emerged as a preferred option for patients requiring redo procedures due to structural valve degeneration. We report from India the first case of the simultaneous transcatheter dual VIV implantation (mitral valve and tricuspid valves) in a high-surgical-risk patient. CASE SUMMARY: A 57-year-old female was presented with a history of rheumatic heart disease, post-mitral valve as well as tricuspid valve replacement (perimount 33 mm) 11 years back...

AimsAn analysis of the budget impact of using a bovine pericardial aortic bioprosthesis (BPAB) or a mechanical valve (MV) in aortic stenosis (AS) patients in Romania.Materials and methodsA decision-tree with a partitioned survival model was used to predict the financial outcomes of using either a BPAB (the Carpentier-Edwards Perimount Magna Ease Valve) or MV in aortic valve replacement (AVR) procedures over a 5-year period. The budget impact of various resource consumption including disabling strokes, reoperations, minor thromboembolic events, major bleeding, endocarditis, anticoagulation treatment and monitoring, and echocardiogram assessments were compared for both types of valves...

OBJECTIVES: The Carpentier Perimount (CP) Magna Ease, the Crown Phospholipid Reduction Treatment (PRT) and the Trifecta bovine pericardial valves have been widely used worldwide. The primary end point of this study was to compare the haemodynamic performance quantified by in vivo echocardiograms of these 3 aortic prostheses. METHODS: The "BEST-VALVE" (comparison of 3 contemporary cardiac bioprostheses: mid-term valve haemodynamic performance) was a single-centre randomized clinical trial to compare the haemodynamic and clinical outcomes of the aforementioned bioprostheses...

In the last decades, minimally invasive procedures have been developed in the therapy of aortic valve disorders. Recently, a novel concept of minimally invasive coronary revascularization in multivessel disease via left anterior mini-thoracotomy demonstrated promising results. Full median sternotomy, as a very invasive procedure, is the standard approach in concomitant surgical aortic valve replacement (sAVR) and coronary bypass grafting (CABG). The aim of our study was to show that the combination of minimal invasive aortic valve replacement via upper mini-sternotomy and coronary artery bypass grafting via left anterior mini-thoracotomy is feasible to avoid full median sternotomy...

Transcatheter aortic valve implantation (TAVI) is currently becoming the method of choice in high-risk patients with severe aortic valve stenosis. Post-TAVI complications are more common owing to the increasing use of the method. The majority of TAVI complications derive from concomitant aortic stenosis with moderate/severe aortic insufficiency, paravalvular leak, and atrioventricular block. The contemporary TAVI qualification process includes a thorough echocardiography and angio-CT of the aorta, which is crucial in assessing valve measurements, determining the position of the coronary arteries branching from the aorta, and choosing the optimal valve size...

Aims of the Study: We evaluated the clinical outcome and the hemodynamic and freedom from structural valve degeneration of two standard aortic bioprostheses. Methods: Clinical results, echocardiographic findings and follow-up data of patients operated for isolated or combined aortic valve replacement with the Perimount or the Trifecta bioprosthesis were prospectively collected, retrospectively analysed and compared. We weighted all the analyses by the inverse of the propensity of choosing either valves. Results: Between April 2015 and December 2019, 168 consecutive patients (all comers) underwent aortic valve replacement with Trifecta (n = 86) or Perimount (n = 82) bioprostheses...

BACKGROUND: Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI) is an emerging treatment alternative to reoperation in high surgical risk patients with a failed mitral bioprostheses. AIM: To describe characteristics and evaluate 30-day outcomes of ViV-TMVI in the Polish population. METHODS: Nationwide registry was initiated to collect data of all patients with failed mitral bioprosthesis undergoing ViV-TMVI in Poland...

BACKGROUND: Leaflet thrombosis after surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) may be caused by blood flow stagnation in the native and neosinus regions. To date, aortic leaflet laceration has been used to mitigate coronary obstruction following TAVR; however, its influence on the fluid mechanics of the native and neosinus regions is poorly understood. This in vitro study compared the flow velocities and flow patterns in the setting of SAVR vs TAVR with and without aortic leaflet lacerations...

BACKGROUND: During the past decade, the Perimount Magna Ease (PME) bioprosthesis has been implanted worldwide for aortic valve replacement (AVR). Recently, the INSPIRIS Resilia (IR) valve has been introduced as the newest generation of pericardial bioprostheses. However, few data have been reported about patients ≤70 years, and no comparisons in terms of hemodynamic performance between these two bioprostheses have been ever reported. METHODS: Patients aged <70 years undergoing AVR were considered for comparison between PME ( n = 238) and IR ( n = 192)...
