Five-Year Outcomes After Bicuspid Aortic Valve Replacement With a Novel Tissue Bioprosthesis. Ann Thorac Surg 2024; 118:173-179. [PMID: 38135262 DOI: 10.1016/j.athoracsur.2023.11.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 11/20/2023] [Accepted: 11/27/2023] [Indexed: 12/24/2023]
Abstract
BACKGROUND This study investigated the safety and effectiveness of surgical aortic valve replacement with RESILIA tissue (Edwards Lifesciences) through 5 years in patients with native bicuspid aortic valves. Outcomes were compared with those for patients with tricuspid aortic valves. METHODS Of 689 patients from the COMMENCE (ProspeCtive, nOn-randoMized, MulticENter) trial who received the study valve, 645 had documented native valve morphology and core laboratory-evaluable echocardiograms from any postoperative visit, which were used to model hemodynamic outcomes over 5 years. Linear mixed-effects models were used to estimate longitudinal changes in mean gradient and effective orifice area. RESULTS Patients with native bicuspid aortic valves (n = 214) were more than a decade younger than those with tricuspid aortic valves (n = 458; 59.8 ± 12.4 years vs 70.2 ± 9.5 years; P < .001). The bicuspid aortic valve cohort exhibited no structural valve deterioration over 5 years, and rates of paravalvular leak and transvalvular regurgitation were low (0.7% and 2.9%, respectively [all mild] at 5 years). These outcomes mirrored those in patients with native tricuspid aortic valves. The model-estimated postoperative mean gradient and effective orifice area, as well as the rate of change of these outcomes, adjusted for age, body surface area, and bioprosthesis size, did not differ between the 2 cohorts. CONCLUSIONS Among patients with bicuspid aortic valves, RESILIA tissue valves demonstrated excellent outcomes to 5 years, including no structural valve deterioration and very low rates of paravalvular and transvalvular regurgitation. These results are encouraging for RESILIA tissue durability in young patients.

Transcatheter or surgical aortic valve implantation: 10-year outcomes of the NOTION trial. Eur Heart J 2024; 45:1116-1124. [PMID: 38321820 PMCID: PMC10984572 DOI: 10.1093/eurheartj/ehae043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 11/26/2023] [Accepted: 01/16/2024] [Indexed: 02/08/2024] Open
Abstract
BACKGROUND AND AIMS Transcatheter aortic valve implantation (TAVI) has become a viable treatment option for patients with severe aortic valve stenosis across a broad range of surgical risk. The Nordic Aortic Valve Intervention (NOTION) trial was the first to randomize patients at lower surgical risk to TAVI or surgical aortic valve replacement (SAVR). The aim of the present study was to report clinical and bioprosthesis outcomes after 10 years. METHODS The NOTION trial randomized 280 patients to TAVI with the self-expanding CoreValve (Medtronic Inc.) bioprosthesis (n = 145) or SAVR with a bioprosthesis (n = 135). The primary composite outcome was the risk of all-cause mortality, stroke, or myocardial infarction. Bioprosthetic valve dysfunction (BVD) was classified as structural valve deterioration (SVD), non-structural valve dysfunction (NSVD), clinical valve thrombosis, or endocarditis according to Valve Academic Research Consortium-3 criteria. Severe SVD was defined as (i) a transprosthetic gradient of 30 mmHg or more and an increase in transprosthetic gradient of 20 mmHg or more or (ii) severe new intraprosthetic regurgitation. Bioprosthetic valve failure (BVF) was defined as the composite rate of death from a valve-related cause or an unexplained death following the diagnosis of BVD, aortic valve re-intervention, or severe SVD. RESULTS Baseline characteristics were similar between TAVI and SAVR: age 79.2 ± 4.9 years and 79.0 ± 4.7 years (P = .7), male 52.6% and 53.8% (P = .8), and Society of Thoracic Surgeons score < 4% of 83.4% and 80.0% (P = .5), respectively. After 10 years, the risk of the composite outcome all-cause mortality, stroke, or myocardial infarction was 65.5% after TAVI and 65.5% after SAVR [hazard ratio (HR) 1.0; 95% confidence interval (CI) 0.7-1.3; P = .9], with no difference for each individual outcome. Severe SVD had occurred in 1.5% and 10.0% (HR 0.2; 95% CI 0.04-0.7; P = .02) after TAVI and SAVR, respectively. The cumulative incidence for severe NSVD was 20.5% and 43.0% (P < .001) and for endocarditis 7.2% and 7.4% (P = 1.0) after TAVI and SAVR, respectively. No patients had clinical valve thrombosis. Bioprosthetic valve failure occurred in 9.7% of TAVI and 13.8% of SAVR patients (HR 0.7; 95% CI 0.4-1.5; P = .4). CONCLUSIONS In patients with severe AS and lower surgical risk randomized to TAVI or SAVR, the risk of major clinical outcomes was not different 10 years after treatment. The risk of severe bioprosthesis SVD was lower after TAVR compared with SAVR, while the risk of BVF was similar.

Abstract
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 This article describes a single-centre cohort of 1016 consecutive SAVRs with the Magna Ease© valve (2008-2014), consisting of an all-comers population. We performed a prospective collection of in-hospital data, systematic clinical and echocardiographic follow-up. Valve-related events were as follows: structural valve deterioration (SVD; according to modified definition criteria), nonstructural valve dysfunction, patient-prosthesis mismatch (PPM). RESULTS Age at SAVR was 73.4 ± 9.5 years; calcified aortic stenosis was the indication to surgery in 59.6%. A total of 974 patients entered the follow-up; 564 were alive at the last follow-up (median duration: 9.8 years) (up to 13.4 years). New York Heart Association class was I or II in 92.1%. Overall survival at 10 years was 56.8 ± 1.8%. Freedom from SVD at 10 was 96.5 ± 0.8% (Kaplan-Meier) and 97.4 ± 0.6% (competing risks) (28 SVD events after 6.9 ± 3.3 years). There were 15 reinterventions for SVD (redo-SAVR and Transcatheter Aortic Valve Implantation (TAVI)); 10-year freedom from reintervention was 97.8 ± 0.6%. Moderate and severe PPM occurred in 26.8% and 5.4%, respectively, without association with late mortality (P = 0.12 for moderate and P = 0.70 for severe PPM). Freedom from valve-related mortality was 97.8 ± 0.5% at 10 years. CONCLUSIONS In this follow-up of the Magna Ease bioprosthesis for SAVR, data indicate good late outcomes (30-day outcomes are excluded). Continued follow-up is required to further support its use in patients with life expectancy >10-12 years.

Role of lipoprotein(a) concentrations in bioprosthetic aortic valve degeneration. Heart 2024; 110:299-305. [PMID: 37643771 DOI: 10.1136/heartjnl-2023-322987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 07/24/2023] [Indexed: 08/31/2023] Open
Abstract
OBJECTIVES Lipoprotein(a) (Lp(a)) is associated with an increased incidence of native aortic stenosis, which shares similar pathological mechanisms with bioprosthetic aortic valve (bAV) degeneration. However, evidence regarding the role of Lp(a) concentrations in bAV degeneration is lacking. This study aims to evaluate the association between Lp(a) concentrations and bAV degeneration. METHODS In this retrospective multicentre study, patients who underwent a bAV replacement between 1 January 2010 and 31 December 2020 and had a Lp(a) measurement were included. Echocardiography follow-up was performed to determine the presence of bioprosthetic valve degeneration, which was defined as an increase >10 mm Hg in mean gradient from baseline with concomitant decrease in effective orifice area and Doppler Velocity Index, or new moderate/severe prosthetic regurgitation. Levels of Lp(a) were compared between patients with and without degeneration and Cox regression analysis was performed to investigate the association between Lp(a) levels and bioprosthetic valve degeneration. RESULTS In total, 210 cases were included (mean age 74.1±9.4 years, 72.4% males). Median time between baseline and follow-up echocardiography was 4.4 (IQR 3.7) years. Bioprostheses degeneration was observed in 33 (15.7%) patients at follow-up. Median serum levels of Lp(a) were significantly higher in patients affected by degeneration versus non-affected cases: 50.0 (IQR 72.0) vs 15.6 (IQR 48.6) mg/dL, p=0.002. In the regression analysis, high Lp(a) levels (≥30 mg/dL) were associated with degeneration both in a univariable analysis (HR 3.6, 95% CI 1.7 to 7.6, p=0.001) and multivariable analysis adjusted by other risk factors for bioprostheses degeneration (HR 4.4, 95% CI 1.9 to 10.4, p=0.001). CONCLUSIONS High serum Lp(a) is associated with bAV degeneration. Prospective studies are needed to confirm these findings and to investigate whether lowering Lp(a) levels could slow bioprostheses degradation.

A Literature Review on the Use of Aortic Allografts in Modern Cardiac Surgery for the Treatment of Infective Endocarditis: Is There Clear Evidence or Is It Merely a Perception?

Abstract
Infective valve endocarditis is caused by different pathogens and 60% of those involve the aortic valve with valve failure. Although S. aureus is recognized as the most frequently isolated causative bacterium associated with IE in high-income countries, Gram-positive cocci nevertheless play a crucial role in promoting infection in relation to their adhesive matrix molecules. The presence of pili on the surface of Gram-positive bacteria such as in different strains of Enterococcus faecalis and Streptococcus spp., grants these causative pathogens a great offensive capacity due to the formation of biofilms and resistance to antibiotics. The indications and timing of surgery in endocarditis are debated as well as the choice of the ideal valve substitute to replace the diseased valve(s) when repair is not possible. We reviewed the literature and elaborated a systematic approach to endocarditis management based on clinical, microbiological, and anatomopathological variables known to affect postoperative outcomes with the aim to stratify the patients and orient decision making. From this review emerges significant findings on the risk of infection in the allograft used in patients with endocarditis and no endocarditis etiology suggesting that the use of allografts has proved safety and effectiveness in patients with both pathologies.

Abstract
Background This study aims to compare valve durability between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). Methods We conducted a systematic review and meta-analysis using data from randomized controlled trials (RCTs). The primary outcome was structural valve deterioration (SVD). Secondary outcomes were bioprosthetic valve failure, reintervention, effective orifice area (EOA), mean pressure gradient, and moderate-severe aortic regurgitation (AR, transvalvular and/or paravalvular). Results Twenty-five publications from seven RCTs consisting of 7,970 patients were included in the analysis with follow-up ranges of 2-8 years. No significant difference was found between the two groups with regard to SVD [odds ratio (OR) 0.72; 95% CI: 0.25-2.12]. The TAVI group was reported to exhibit a statistically significant higher risk of reintervention (OR 2.03; 95% CI: 1.34-3.05) and a moderate-severe AR (OR 6.54; 95% CI: 3.92-10.91) compared with the SAVR group. A trend toward lower mean pressure gradient in the TAVI group [(mean difference (MD) -1.61; 95% CI: -3.5 to 0.28)] and significant higher EOA (MD 0.20; 95% CI: 0.08-0.31) was noted. Conclusion The present data indicate that TAVI provides a comparable risk of SVD with favorable hemodynamic profile compared with SAVR. However, the higher risk of significant AR and reintervention was demonstrated. Systematic Review Registration PROSPERO (CRD42022363060).

Abstract
Structural valve deterioration (SVD) of bioprosthetic heart valves (BHVs) has great clinical and economic consequences. Notably, immunity against BHVs plays a major role in SVD, especially when implanted in young and middle-aged patients. However, the complex pathogenesis of SVD remains to be fully characterized, and analyses of commercial BHVs in standardized-preclinical settings are needed for further advancement. Here, we studied the immune response to commercial BHV tissue of bovine, porcine, and equine origin after subcutaneous implantation into adult α1,3-galactosyltransferase-knockout (Gal KO) mice. The levels of serum anti-galactose α1,3-galactose (Gal) and -non-Gal IgM and IgG antibodies were determined up to 2 months post-implantation. Based on histological analyses, all BHV tissues studied triggered distinct infiltrating cellular immune responses that related to tissue degeneration. Increased anti-Gal antibody levels were found in serum after ATS 3f and Freedom/Solo implantation but not for Crown or Hancock II grafts. Overall, there were no correlations between cellular-immunity scores and post-implantation antibodies, suggesting these are independent factors differentially affecting the outcome of distinct commercial BHVs. These findings provide further insights into the understanding of SVD immunopathogenesis and highlight the need to evaluate immune responses as a confounding factor.

[PMID: 36183748 DOI: 10.1016/j.athoracsur.2022.09.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 09/09/2022] [Accepted: 09/19/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND Current bioprostheses are considered to have improved durability and better hemodynamic performance compared with previous designs, but there are limited comparative data on late outcomes. METHODS From 2009 through 2011, 300 adults with severe aortic valve stenosis undergoing aortic valve replacement (AVR) were randomly assigned to receive Edwards Magna, St Jude Epic, or Sorin Mitroflow bioprostheses (n = 100, n = 101, n = 99, respectively). Overall survival was analyzed using Kaplan-Meier and Cox proportional hazards methods, whereas competing risk analysis was used for all time-to-event outcomes. Serial echocardiographic data were fitted with longitudinal models stratified by implant valve size. RESULTS During median follow-up of 9.8 years (interquartile range, 8.7-10.2), 10-year survival was 50% for the Magna group, 42% for the Epic group, and 41% for the Mitroflow group (P = .415). Cumulative risk of stroke was 9% at 10 years, and rates were comparable for the three groups. Indexed aortic valve area and mean gradients were similar among the three groups receiving 19 mm and 21 mm valves, but in larger (23 mm or more) prostheses, gradients were lower (P < .001) and indexed aortic valve areas were higher in the Magna group (P < .001). The 10-year risk of endocarditis differed by group (P = .033), with higher incidence in the Mitroflow vs the Magna group (7% vs 0%, P = .019). Late risk of reinterventions in the Mitroflow group was 22%, compared with 0% in the Magna group (P < .001) and 5% in the Epic group (P = .008). CONCLUSIONS The Magna valve had the lowest gradients and largest indexed aortic valve area with larger implant sizes. The Mitroflow bioprosthesis is associated with an increased rate of reintervention and possible increased risk of infection compared with Magna and Epic valves.

Abstract
BACKGROUND Recent studies reported higher-than-expected rates of early structural valve degeneration (SVD) and/or reoperation of externally mounted leaflet aortic bioprosthesis compared with others. This meta-analysis aims to compare the outcomes of bioprostheses with externally versus internally mounted leaflet design in patients who underwent surgical aortic valve replacement (SAVR). METHODS MEDLINE and EMBASE were searched through November 2021 to identify comparative studies investigating outcomes following SAVR with either externally or internally mounted leaflet aortic bioprosthesis. Outcomes of interest were reoperation for SVD or any cause and all-cause mortality. RESULTS Our analysis included 15 observational studies that enrolled a total of 23,539 patients who underwent SAVR using externally mounted (n = 9338; 39.7%) or internally mounted leaflet (n = 14,201; 60.3%) bioprostheses. Externally mounted valves consisted of the Trifecta (Abbott, St Paul, MN) (n = 6146) and the Mitroflow (LivaNova, London, UK) (n = 3192), and all internally mounted valves were the Perimount (Edwards Lifesciences, Irvine, CA). Externally mounted valves compared with the Perimount were associated with higher reoperation rates for SVD [hazard ratio (HR) 3.55, 95% confidence interval (CI) 2.67-4.72; P < 0.001] and any cause (HR 9.36, 95% CI 3.70-23.67; P < 0.001). Furthermore, externally mounted valves demonstrated higher all-cause mortalities (HR 1.33, 95% CI 1.13-1.56; P < 0.001). CONCLUSIONS The present study summarizing updated evidence revealed higher reoperation rates and all-cause mortalities in patients with externally mounted leaflet aortic bioprostheses compared with those with internally mounted design. Choosing the right SAVR valve type is critical part of lifetime management of aortic valve disease.

Abstract
OBJECTIVES Long-term real-world outcomes are critical for informing decisions about biological (Bio) or mechanical (Mech) prostheses for aortic valve replacement, particularly in patients aged between 50 and 65 years. The objective was to compare long-term survival and major adverse cardiac and cardiovascular events (ie, stroke, reoperation, and major bleeding) within this population. METHODS This was a multicenter observational study including all patients aged between 50 and 65 years who underwent an aortic valve replacement because of severe isolated aortic stenosis between the years 2000 and 2018. A total of 5215 patients from 27 Spanish hospitals were registered with a follow-up of 15 years. Multivariable analyses, including a 2:1 propensity score matching (1822 Mech and 911 Bio) and competing risks analyses were applied. RESULTS Bio prostheses were implanted in 19% of patients (n = 992). No significant differences were observed between matched groups in long-term survival (hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.88-1.47; P = .33). Stroke rates were higher for Mech prostheses, but not significant (HR, 0.72; 95% CI, 0.50-1.03; P = .07). Finally, higher rates of major bleeding were found in the Mech group (HR, 0.65; 95% CI, 0.49-0.87; P = .004), whereas reoperation was more frequent among the Bio group (HR, 3.04; 95% CI, 1.80-5.14; P < .001). Bio prostheses increased from 13% in the period from 2000 to 2008 to 24% in 2009 to 2018. CONCLUSIONS Long-term survival was comparable among groups in patients between 50 and 65 years of age. Mech prostheses were associated with a higher risk of major bleeding, whereas Bio prostheses entailed higher reoperation rates. Bio prostheses seem a reasonable choice for patients between 50 and 65 years in Spain.

Abstract
Transcatheter aortic valve implantation (TAVI) has become the standard of care in symptomatic older patients with severe aortic stenosis regardless of surgical risk. With the development of newer generation transcatheter bioprostheses, improved delivery systems, better preprocedure planning with imaging guidance, increased operator experience, shorter hospital length of stay, and low short- and mid-term complication rates, TAVI is gaining popularity among younger patients at low or intermediate surgical risk. Long-term outcomes and durability of transcatheter heart valves have become substantially important for this younger population due to their longer life expectancy. The lack of standardized definitions of bioprosthetic valve dysfunction and disagreement about how to account for the competing risks made comparison of transcatheter heart valves with surgical bioprostheses challenging until recently. In this review, the authors discuss the mid- to long-term (≥ 5 years) clinical outcomes observed in the landmark TAVI trials and analyze the available long-term durability data emphasizing the importance of using standardized definitions of bioprosthetic valve dysfunction.

Abstract
BACKGROUND With guidelines progressively recommending bioprosthetic aortic valves in younger patients, a greater emphasis is placed on structural valve deterioration (SVD) as an important clinical endpoint for both transcatheter and surgically implanted valves. However, SVD of bioprosthetic valves is a complex entity with varying definitions in the literature and a multifaceted pathogenesis. AIM This review first aims to establish the most updated definitions of SVD as per the literature. We then explore the patient- and valve-related factors that play the greatest roles in facilitating early SVD. METHODS A PubMed literature review was conducted to identify the relevant research in this field within the past two decades. CONCLUSION Increasing rates of obesity and metabolic syndrome pose a significant risk to the longevity of bioprosthetic valves. Additionally, externally mounted valves have proven to sacrifice durability for superior haemodynamics. Bioprosthetic SVD continues to be a multifactorial issue that will require various patient- and valve-related factors to be addressed.

Abstract
Transcatheter aortic valve implantation (TAVI) has grown exponentially within the cardiology and cardiac surgical spheres. It has now become a routine approach for treating aortic stenosis. Several concerns have been raised about TAVI in comparison to conventional surgical aortic valve replacement (SAVR). The primary concerns regard the longevity of the valves. Several factors have been identified which may predict poor outcomes following TAVI. To this end, the lesser-used finite element analysis (FEA) was used to quantify the properties of calcifications which affect TAVI valves. This method can also be used in conjunction with other integrated software to ascertain the functionality of these valves. Other imaging modalities such as multi-detector row computed tomography (MDCT) are now widely available, which can accurately size aortic valve annuli. This may help reduce the incidence of paravalvular leaks and regurgitation which may necessitate further intervention. Structural valve degeneration (SVD) remains a key factor, with varying results from current studies. The true incidence of SVD in TAVI compared to SAVR remains unclear due to the lack of long-term data. It is now widely accepted that both are part of the armamentarium and are not mutually exclusive. Decision making in terms of appropriate interventions should be undertaken via shared decision making involving heart teams.

Abstract
The Trifecta aortic valve is a prosthesis with externally mounted leaflets and a stent which may be deformed during implant. Our aim was to know if the use of the holder as a protection device during the knotting has an impact on the incidence of structural valve deterioration (SVD) or endocarditis. Prospective cohort study where all patients who underwent aortic valve replacement with a Trifecta aortic valve between 2013 and 2018 were included. The use of the holder as a protection device was collected in a database. Propensity-score matched methods were used and analyses were based on competing events. Death without SVD or prosthesis replacement not due to SVD was considered competing events. 782 patients were included, 352 pairs after the matching. Rates of SVD at 5 and 8 years were 5.8% (95% CI 3.5-8.7) and 13.6% (95% CI 9.2-18.9) in the group without holder and 2.3% (95% CI 1-4.5) and 7% (95% CI 4.2-10.8) in the group with holder; sHR = 0.49 (95% CI 0.27-0.86; P = 0.015). The risk of endocarditis at 8 years was 4.8% (95% CI 2.8-7.4) in the group without holder and 2.3% (95% CI 1.1-4.3) in the group with holder, sHR = 0.49 (95% CI 0.21-1.15, P = 0.1). The use of holder as a protection device during the knotting of the Trifecta aortic valve is associated with less risk of SVD.

Abstract
Patients who need a prosthetic aortic heart valve may decide, working with their cardiologist and cardiac surgeon, among a variety of options: surgical or transcatheter approach, bioprosthetic or mechanical valve, or a Ross procedure if suitable to their age and anatomy. This review article examines the evidence for survival benefit with mechanical aortic valves, discusses bioprosthetic structural valve degeneration and its consequences, and considers the risks of redo aortic valve surgery or subsequent valve-in-valve (ViV) transcatheter intervention. It highlights the unique characteristics of the On-X aortic valve, including the US Food and Drug Administration approved and American College of Cardiology/American Heart Association guideline supported reduced anticoagulation target INR of 1.5 to 2.0, and discusses the PROACT Xa trial comparing apixaban vs warfarin anticoagulation. The choice of prosthetic valve should be individualized, carefully considering each patient's unique circumstances. In that context, the On-X aortic valve offers a potential lifetime solution without need for a repeat operation, while minimizing the risks of long-term anticoagulation. In an era of enthusiasm for bioprosthetic and transcatheter-based approaches, the option of a second-generation bileaflet mechanical valve with optimized hemodynamics-the On-X aortic valve-may well align with patient expectations.

Abstract
Background The impact of transcatheter aortic valve replacement (TAVR) leaflet design on long-term device performance is still unknown. This study sought to compare the clinical and hemodynamic outcomes of intra- (IA) versus supra-annular (SA) TAVR designs up-to 10-years following implantation. Methods Consecutive patients with at least 5-years follow-up following TAVR for severe symptomatic aortic stenosis from June 2007 to December 2016 were included. Bioprosthetic valve failure (BVF) and hemodynamic valve deterioration (HVD) were defined according to VARC-3 updated definitions and estimated using cumulative incidence function to account for the competing risk of death. Results A total of 604 patients (82 years; 53% female) were analyzed and divided into IA (482) and SA (122) groups. Overall survival rates at 10-years were similar (IA 15%, 95%CI: 10–22; SA 11%, 95%CI: 6–20; p = 0.21). Compared to the SA TAVR, mean transaortic gradients were significantly higher and increased over time in the IA group. IA TAVRs showed higher 10-year cumulative incidences of BVF (IA 8% vs. SA 1%, p = 0.02) and severe HVD (IA 5% vs. SA 1%, p = 0.05). The occurrence of BVF and HVD in the IA group occurred primarily in the smallest TAVR devices (20–23-mm). After excluding these sizes, the cumulative incidences of BVF (IA 5% vs. SA 1%, p = 0.40) and severe HVD (IA 2% vs. SA 1%, p = 0.11) were similar. Conclusion In this study, TAVR leaflet design had no impact on survival at 10-years. IA devices showed higher transaortic gradients and cumulative incidences of HVD and BVF predominantly occurring in the smallest valve sizes.

Abstract
Valve replacement is the main therapy for valvular heart disease, in which a diseased valve is replaced by mechanical heart valve (MHV) or bioprosthetic heart valve (BHV). Since the 2000s, BHV surpassed MHV as the leading option of prosthetic valve substitute because of its excellent hemocompatible and hemodynamic properties. However, BHV is apt to structural valve degeneration (SVD), resulting in limited durability. Calcification is the most frequent presentation and the core pathophysiological process of SVD. Understanding the basic mechanisms of BHV calcification is an essential prerequisite to address the limited-durability issues. In this narrative review, we provide a comprehensive summary about the mechanisms of BHV calcification on 1) composition and site of calcifications; 2) material-associated mechanisms; 3) host-associated mechanisms, including immune response and foreign body reaction, oxidative stress, metabolic disorder, and thrombosis. Strategies that target these mechanisms may be explored for novel drug therapy to prevent or delay BHV calcification.

Abstract
OBJECTIVES The goal of this study was to assess the performance and incidence of the deterioration of the Labcor Dokimos bioprosthetic aortic valve. METHODS We performed a retrospective medical chart review of 116 patients who underwent surgical aortic valve replacement with the Labcor Dokimos aortic valve between 2010 and 2018. Abstracted data included patient demographic and echocardiographic data. Patients were divided into 2 groups: patients with structural valve deterioration (SVD) and patients without SVD. RESULTS Among the patients with complete follow-up (n = 95), 10 patients were excluded because they died within a year; 85 patients were included in the final analysis. Of the 85 patients, 32 (38%) developed SVD; 22 (26%) had severe SVD, 15 (18%) of whom underwent reintervention. The most common aetiology of SVD was severe central aortic regurgitation, which was detected in 91% of the patients who had severe SVD. The average time from operation to severe SVD was 4.7 years with a minimum of 1.5 years and a maximum of 7.9 years. CONCLUSIONS Bioprosthetic aortic valve deterioration due to severe aortic regurgitation is common and occurs early with the Labcor Dokimos valve. This occurrence needs to be furthered investigated in larger registries.

Immobile Leaflets at Time of Bioprosthetic Valve Implantation: A Novel Risk Factor for Early Bioprosthetic Failure: A Novel Risk Factor for Early Bioprosthetic Failure. Heart Lung Circ 2022; 31:1166-1175.

Abstract
OBJECTIVES The clinical implications of finding immobile leaflet(s) at the time of bioprosthetic valve implantation but with acceptable prosthetic haemodynamics are uncertain. We sought to determine the characteristics of such patients and their impact on outcome. METHODS Patients with immobile leaflet at the time of surgical bioprosthetic valve implantation were identified retrospectively by a systematic search of an institutional echocardiography database (2010-2020). Intraoperative echocardiograms were reviewed de-novo to confirm immobile leaflet(s) at the time of implantation. Cases were matched 1:2 to controls with normal bioprosthetic leaflets motion for age, sex, prosthesis position, prosthesis model, size, year of implantation, and pre-implantation left ventricular ejection fraction. Proportional hazards method was used to analyse the composite endpoint of stroke, valve thrombosis or re-intervention. RESULTS Immobile leaflet at the time of bioprosthetic valve implantation were found in 26 patients (median age 71 ys 39% males) following tricuspid (n=13), mitral (n=11) and aortic (n=2) valve replacements; 96% received porcine prostheses; prosthesis size was 27 mm or larger in 92%. Immobile leaflet were recorded on intraoperative reports in 16 (62%) cases. It resulted in elevated gradient or mild-moderate prosthetic regurgitation in three (12%), but none led to immediate corrective action intraoperatively. At median follow-up of 21 (4-50) months, presence of immobile leaflet was associated with composite clinical endpoint of stroke, valve thrombosis or re-intervention (hazard ratio 6.8 95% CI 1.8-25.2 p<0.01) compared to controls. CONCLUSION Immobile leaflet immediately post-bioprosthetic valve implantation is frequently under-recognised intraoperatively and appears to be associated with early bioprosthetic dysfunction and worse clinical outcome.

Abstract
BACKGROUND Recent reports suggest an increased rate of early structural valve degeneration (SVD) in the Trifecta bioprosthesis (Abbott Cardiovascular). We sought to compare the intermediate-term outcomes of the Magna (Edwards Life Sciences) and Trifecta valves. METHODS All surgical aortic valve replacements (SAVRs) with Trifecta or Magna/Magna Ease bioprostheses at an academic medical center were extracted from an institutional database. Patients who survived until after discharge (2011-2019) were included. The primary outcome was valve failure for any reason requiring reintervention or contributing to death, identified by reintervention or review of cause of death. Time to failure was estimated with Kaplan-Meier analysis and Cox Proportional Hazards Modeling. RESULTS Out of 1444 patients, 521 (36%) underwent Trifecta and 923 (64%) underwent Magna implantation with a median follow-up of 27.6 months. Trifecta patients had larger median valve size (25 vs. 23 mm, p < .001) and lower median gradient (8.0 vs. 10.9 mmHg, p < .001). Trifecta patients had higher 48-month estimated failure rates (20.2 ± 7.6% vs. 2.6 ± 0.7%, p < .0001), with failure rates of 21.4 versus 9.2 failures per 1000 person-years (p < .001). After risk-adjustment, Trifecta patients had a 5.3 times hazard of failure (95% confidence interval: 2.78-12.34, p < .001) compared to Magna patients. Only Trifecta valves failed due to sudden aortic regurgitation, 8 out of 521 (1.5%). CONCLUSION Despite lower postoperative mean gradients, the Trifecta bioprosthesis may have an increased risk of intermediate-term SVD. Further research is warranted to confirm the potential for sudden valve failure.

Abstract
IMPORTANCE The performance of bioprosthetic aortic valves is usually assessed in single valve models or head-to-head comparisons. National databases or registries offer the opportunity to investigate all available valve models in the population and allows for a comparative assessment of their performance. OBJECTIVE To analyze the long-term rates of reintervention, all-cause mortality, and heart failure hospitalization associated with commonly used bioprosthetic aortic valves and to identify valve model groups with deviation in clinical performance. DESIGN, SETTING, AND PARTICIPANTS This population-based, nationwide cohort study included all adult patients who underwent surgical aortic valve replacement (with or without concomitant coronary artery bypass surgery or ascending aortic surgery) in Sweden between January 1, 2003, and December 31, 2018. Patients were identified from the SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) registry. Patients with concomitant valve surgery, previous cardiac surgery, and previous transcatheter valve replacement were excluded. Follow-up was complete for all participants. Data were analyzed from March 9, 2020, to October 12, 2021. EXPOSURES Primary surgical aortic valve replacement with the Perimount, Mosaic/Hancock, Biocor/Epic, Mitroflow/Crown, Soprano, and Trifecta valve models. MAIN OUTCOMES AND MEASURES The primary outcome was cumulative incidence of reintervention, defined as a subsequent aortic valve operation or transcatheter valve replacement. Secondary outcomes were all-cause mortality and heart failure hospitalization. Regression standardization and flexible parametric survival models were used to account for intergroup differences. Mean follow-up time was 7.1 years, and maximum follow-up time was 16.0 years. RESULTS A total of 16 983 patients (mean [SD] age, 72.6 [8.5] years; 10 685 men [62.9%]) were included in the analysis. The Perimount valve model group had the lowest and the Mitroflow/Crown valve model group had the highest cumulative incidence of reintervention. The estimated cumulative incidence of reintervention at 10 years was 3.6% (95% CI, 3.1%-4.2%) in the Perimount valve model group and 12.2% (95% CI, 9.8%-15.1%) in the Mitroflow/Crown valve model group. The estimated incidence of reintervention at 10 years was 9.3% (95% CI, 7.3%-11.3%) in the Soprano valve model group. CONCLUSIONS AND RELEVANCE Results of this study showed that the Perimount valve was the most commonly used and had the lowest incidence of reintervention, all-cause mortality, and heart failure hospitalization, whereas the Mitroflow/Crown valve had the highest rates. These findings highlight the need for clinical vigilance in patients who receive either a Soprano or Mitroflow/Crown aortic bioprosthesis.

Abstract
Bioprosthetic heart valves (BHVs) are commonly used to replace severely diseased heart valves but their susceptibility to structural valve degeneration (SVD) limits their use in young patients. We hypothesized that antibodies against immunogenic glycans present on BHVs, particularly antibodies against the xenoantigens galactose-α1,3-galactose (αGal) and N-glycolylneuraminic acid (Neu5Gc), could mediate their deterioration through calcification. We established a large longitudinal prospective international cohort of patients (n = 1668, 34 ± 43 months of follow-up (0.1–182); 4,998 blood samples) to investigate the hemodynamics and immune responses associated with BHVs up to 15 years after aortic valve replacement. Early signs of SVD appeared in <5% of BHV recipients within 2 years. The levels of both anti-αGal and anti-Neu5Gc IgGs significantly increased one month after BHV implantation. The levels of these IgGs declined thereafter but anti-αGal IgG levels declined significantly faster in control patients compared to BHV recipients. Neu5Gc, anti-Neu5Gc IgG and complement deposition were found in calcified BHVs at much higher levels than in calcified native aortic valves. Moreover, in mice, anti-Neu5Gc antibodies were unable to promote calcium deposition on subcutaneously implanted BHV tissue engineered to lack αGal and Neu5Gc antigens. These results indicate that BHVs manufactured using donor tissues deficient in αGal and Neu5Gc could be less prone to immune-mediated deterioration and have improved durability. In a large cohort of patients who underwent aortic valve replacement, antibody responses to glycans present in bioprosthetic heart valves, notably galactose-α1,3-galactose and N-glycolylneuraminic acid, were implicated in valve calcification and deterioration.

Abstract
INTRODUCTION Trifecta bioprosthesis claims favourable haemodynamic performance. However, reports of structural valve deterioration (SVD) raise concerns of its long-term durability. We assessed outcomes with the Trifecta valve over a 10-year period. METHODS All patients receiving Trifecta bioprostheses between October 2011 and October 2020 were included. Perioperative and survival characteristics were prospectively collated in an independent database. Re-intervention was recorded as a surrogate for SVD. RESULTS 944 patients (mean age 72.82 years ± 8.13, 58% male) underwent aortic valve replacement with the Trifecta valve. At 10-years, 1.4% of patients required a redo operation, giving an overall freedom from re-intervention of 98.6%. The mean time to re-intervention was 48.87 months. Survival was 73.58% and 76.92% in patients who did not require re-intervention vs re-intervention group, respectively. CONCLUSIONS In a large, single-centre cohort, the Trifecta aortic bioprosthesis had a 1.4% all-cause re-intervention rate at 10-years, with insignificant impact on survival.

Abstract
OBJECTIVES The goal of this multicentre retrospective study was to compare long-term clinical and haemodynamic outcomes of the Carpentier-Edwards Magna Ease (CEME) bioprosthesis by patient age. METHODS We included consecutive patients who underwent isolated and combined surgical aortic valve replacement (AVR) with CEME valve between January 2008 and March 2020 at 4 cardiac surgery centres in Italy. Survival distribution was evaluated at follow-up according to age and surgery type (combined or isolated AVR), together with freedom from structural valve deterioration (SVD), reoperation and combined events, i.e. SVD, reoperation, endocarditis and thromboembolic events. RESULTS A total of 1027 isolated and 1121 combined AVR were included; 776 patients were younger than 65 years whereas 1372 were 65 years or older. The 30-day Valve-Academic-Research-Consortium mortality was 2% (<65 years) and 6% (≥ 65 years) (P < 0.001), whereas it was 3% for isolated AVR and 7% for combined AVR (P < 0.001). The 12-year survival was 81% for those younger than 65 years vs 45% for those equal to or older than 65 years (P < 0.001), whereas they were 61% vs 49% for isolated and combined AVR (P = 0.10). The 12-year freedom from combined events, excluding death, was 79% for those younger than 65 years vs 87% for those equal to or older than (P = 0.51), whereas they were 83% for isolated and 86% for combined AVR (P = 0.10). The 12-year freedom from SVD was 93% and 93% in patients younger than 65 and those equal to or older than 65 years (P = 0.63), and the results were comparable even in cases with isolated and combined AVR (92% vs 94%, P = 0.21). A multivariable Cox analysis including gender, presence of patient-prosthesis mismatch, isolated AVR and age showed that only the age was an independent risk factor for the incidence of SVD (P = 0.029). CONCLUSIONS Outcomes from this large multicentre analysis demonstrated that a CEME bioprosthesis provides good clinical results and long-term durability even in patients younger than 65 years. Furthermore, the hazard for SVD has been shown to be lower for older age. CLINICAL TRIAL REGISTRATION NUMBER 105n/AO/21.

Long-term durability after surgical aortic valve replacement with the Trifecta and the Intuity valve-a comparative analysis. Eur J Cardiothorac Surg 2021; 61:416-424.

Abstract
OBJECTIVES Long-term durability of surgical bio-prostheses is a key factor, especially in the era of transcatheter aortic valve replacement. We compared the incidence of structural valve deterioration (SVD) between patients undergoing surgical aortic valve replacement (SAVR) with the Trifecta (Abbott Laboratories, Abbott Park, IL, USA) or the Intuity valve (Edwards Lifesciences, Irvine, CA, USA). METHODS Between April 2010 and May 2020, 1118 patients underwent SAVR with the Trifecta (n = 346) and the Intuity (n = 772) valve at a single centre. A total of 1070 patients (Trifecta n = 298, Intuity n = 772) were analysed after the exclusion of patients with pure regurgitation and endocarditis. Retro- and prospective echocardiographic and clinical follow-up was performed. Cox proportional hazards regression models were performed to identify prognostic factors for SVD, aortic re-interventions and mortality. RESULTS With 27 cases (Trifecta n = 23, Intuity n = 4) of SVD observed, cumulative incidence of SVD was significantly higher in the Trifecta cohort (P < 0.001). Implantation of a Trifecta valve [hazard ratio (HR) 11.20; 95% confidence interval 3.79-33.09], log-transformed preoperative creatinine (HR 2.47; 1.37-4.44) and sex (male HR 0.42; 0.19-0.92) emerged as prognostic factors of SVD. A significantly higher cumulative incidence of re-interventions was observed in the Trifecta cohort (P = 0.004) and valve type was an independent time-varying risk factor (HR at 12 months 2.78; 95% confidence interval 1.42-5.45). Overall, no significant differences in all-cause mortality were observed between the groups (log-rank test: P = 0.052). CONCLUSIONS SVD was significantly more frequent in patients receiving a Trifecta valve and its implantation was an independent risk factor for the occurrence of SVD and aortic valve re-interventions. This comparative analysis of 2 low-gradient bioprosthesis put the long-term durability of the Trifecta valve in question and need to be taken into consideration when performing bioprosthetic SAVR.

Abstract
Mechanical valves and bioprosthetic heart valves are widely used for aortic valve replacement (AVR). Mechanical valves are associated with risk of bleeding because of oral anticoagulation, while the durability and structural valve deterioration (SVD) represent the main limitation of the bioprosthetic heart valves. The implantation of bioprosthetic heart valves is increasing precipitously due aging population, and the widespread use of transcatheter aortic valve replacement (TAVR). TAVR has become the standard treatment for intermediate or high surgical risk patients and a reasonable alternative to surgery for low risk patients with symptomatic severe aortic stenosis. Moreover, TAVR is increasingly being used for younger and lower-risk patients with longer life expectancy; therefore it is important to ensure the valve durability for long-term transcatheter aortic valves. Although the results of mid-term durability of the transcatheter heart valves are encouraging, their long-term durability remains largely unknown. This review summarises the definitions, mechanisms, risk factors and assessment of SVD; overviews available data on surgical bioprosthetic and transcatheter heart valves durability.

Abstract
OBJECTIVE Recent studies suggested higher rates of early structural valve degeneration or reintervention for the Trifecta valve compared to other valves. Thus, we conducted a systematic review and meta-analysis comparing the outcomes of the Trifecta valve and the Perimount valves in patients who underwent a surgical aortic valve replacement (SAVR). METHODS All randomized control trials and observational studies which investigated the outcomes of the Trifecta valve and Perimount valves were identified with PubMed and EMBASE. The endpoints were the rates of reintervention and all-cause mortality. Hazard ratios (HRs) for reintervention and all-cause mortality were combined with the random-effects model. RESULTS Our search identified 6 eligible observational studies which enrolled a total of 11,135 patients who underwent SAVR with either the Trifecta valve (n = 4932) or Perimount (n = 6203). Pooled analyses demonstrated that the reintervention rates were significantly higher with the Trifecta valve compared with Perimount valves (HR [95% confidence interval {CI}] = 3.16 [1.83-5.46]; p < .0001; I2 = 40%). In contrast, all-cause mortality was not significantly different between the two groups (HR [95% CI] = 1.09 [0.75-1.58]; p = .32, I2 = 12%). CONCLUSION Our analysis showed that AVR with the Trifecta valve was associated with higher rates of reintervention compared for that with the Perimount valve. Although further long-term randomized trials are warranted, surgeons need to be cautious when choosing a bioprosthetic valve for patients undergoing SAVR.

Abstract
OBJECTIVES Updated European guidelines recommend annual echocardiographic evaluation after bioprosthetic surgical aortic valve replacement (bio-SAVR). Given the increased demand on health care resources, only clinically relevant controls can be prioritized. We therefore aimed to explore reintervention rates following bio-SAVR. METHODS From the nationwide Danish Register of Surgical Procedures, we identified all patients ≥40 years with isolated bio-SAVR ± concomitant coronary artery bypass graft surgery (CABG) during 2000-2016. In 90-day reintervention-free survivors, we assessed aortic valve reintervention rates (primary outcome) and all-cause mortality rates (secondary outcome) at 1, 3 and 5 years with total follow-up until 31 December 2017 and further estimated annual theoretical echocardiographic control visits. RESULTS In 10 518 patients with bio-SAVR (+CABG 39.7%), we observed low reintervention rates at 1, 3 and 5 years, but with high rates of all-cause mortality; i.e. 5-year reintervention rate of 3.7/1000 person-years (≤1.5%) and 5-year mortality rate of 21.7/1000 person-years. Accounting for the competing risk of death, 5-year rates were inversely related to age group and remained relatively low across all age categories but increased gradually in the long term. A significant proportion of reinterventions were presumed due to infectious endocarditis (48% at 3 years, 37% at 5 years). With annual transthoracic echocardiography, the theoretical ratio of echocardiographies per reintervention in the first 5 years was 248, and 425 when endocarditis events were excluded. CONCLUSION Reintervention rates within the first 5 years following bio-SAVR were relatively rare, and with a substantial number due to endocarditis.

Abstract
BACKGROUND Limited mid-term durability of 12A/LX Mitroflow bioprosthesis has been reported. Aim of the study was to ascertain the pathologic substrates and possible mechanisms of structural valve deterioration in explants from animals and humans. METHODS Nine aortic 12A/LX Mitroflow bioprostheses preserved in hypotonic solution and three aortic 12A/LX bioprostheses, preserved in isotonic solution, were explanted from juvenile sheep, mean time from implant 95.66 ± 36.04 days and 132.33 ± 28.88 days from implant respectively. One stented unimplanted 12A/LX Mitroflow preserved in isotonic colution before glutaraldeyde fixation served as control. Ten aortic 12A/LX Mitroflow bioprostheses were explanted from humans because of severe dysfunction: five children, (3 females and 2 males, mean age 14.19 ± 4.77 years, range 11-21), 26 ± 8.24 months from implant and 5 adults (4 females and 1 male, mean age 57.4 ± 19.85 years, range 31-72), 64.4 ± 26.94 months from implant. X-ray, histology, and transmission electron microscopy were carried out as well as spectroscopy for calcium (Ca++) and phosphorus (P) content in human explants. RESULTS Explants, from both animals and humans, showed cusp folding and stiffness, with coarse calcific deposits at gross examination and X-ray. Severe collagen denaturation, plasma insudation and massive calcification, involving both collagen and cell debris, were observed microscopically. Mean Ca++ content of 183.27 ± 62.48 and P content of 94.35 ±33.76 mg/g dry weight was found in children and Ca++ content of 205.49 ± 2.23 and P content of 99.75 ± 0.11 mg/g dry weight in adults. Obstructive fibrous tissue overgrowth was detected in 6 human cases. CONCLUSIONS Collagen denaturation was observed in pericardial Mitroflow 12A/LX bioprosthesis with premature structural valve deterioration. Optimal collagen fixation and preservation as well as phospholipids reduction by removing cell debris, as employed in the novel CROWN PRT Mitroflow bioprosthesis, are expected to solve the flaw and achieve long-term durability.

Abstract
AIMS Native valve aortic stenosis is associated with adverse remodelling of the left ventricle and remodelling is stopped or even reversed with aortic valve replacement (AVR). However, the degeneration of bioprostheses and development of structural valve deterioration (SVD) may affect this. METHODS AND RESULTS To assess the association with SVD, remodelling and outcome 451 patients from a single surgical centre who had undergone AVR with a Mitroflow pericardial bioprosthesis were studied. All patients were assessed in 2014 and a subgroup of patients (N = 327) were re-exanimated again after at least 18 months [median time of 27 (interquartile range, IQR 26-33) months] including echocardiography, measurements of N-terminal pro-brain natriuretic peptide, and assessment of functional status. SVD was based on echocardiography. Moderate SVD was present in 63 patients (14%) and severe SVD in 19 (4%), in the subgroup with follow-up echocardiography 48 patients (15%) patients had moderate to severe SVD at first examination. Patients with SVD had significantly greater increase in left ventricular (LV) mass index [21.6 g/m2 (IQR 5.7-48.3 g/m2) vs. 9.1 g/m2 (-8.6 to 27.3 g/m2), P = 0.01]. Further, patients with SVD had lower LV ejection fraction [55% (IQR 51-62%) vs. 60% (IQR 54-63%), P = 0.01] at follow-up. During follow-up, 94 patients (21%) met the composite endpoint of death or reoperation due to SVD and 41 patient readmitted for heart failure. In multivariable Cox regression analysis, severe SVD [hazard ratio (HR) 2.64 (1.37-5.07), P = 0.004] was associated with composite endpoint, and readmission for heart failure [HR 3.82 (1.53-9.51), P = 0.004]. CONCLUSION SVD in aortic bioprostheses is associated with adverse LV remodelling and adverse outcome.

Abstract
OBJECTIVES Despite promising short- and mid-term results for durability of the Trifecta valve, contradictory reports of early structural valve deterioration (SVD) do exist. We investigated the incidence of SVD after surgical aortic valve replacement (SAVR) with the Trifecta in our single-centre experience. METHODS Data of 347 consecutive patients (mean age 71.6 ± 9.5 years, 63.4% male) undergoing SAVR with the Trifecta between 2011 and 2017 were analysed. Clinical and echocardiographic reports were obtained with a median follow-up of 41 months (1114 patient years). RESULTS Isolated SAVR was performed in 122 patients (35.2%), whereas 225 patients (64.8%) underwent concomitant procedures. The median EuroSCORE II was 4.0 (0.9; 7.1) and 30-day mortality was 3.7% (n = 13). Kaplan-Meier estimates for the freedom of overall mortality at 1, 5 and 7 years were 88.7 ± 1.7%, 73.7 ± 2.6% and 64.7 ± 4.2%, respectively. SVD was observed in 25 patients (7.2%) with a median time to first diagnosis of 73 months. Freedom of SVD was 92.5 ± 0.9% at 5 years and 65.5 ± 7.1% at 7 years. Thirteen patients underwent reintervention for SVD (6 re-SAVR, 7 valve-in-valve), resulting in a freedom of reintervention for the SVD of 98.5 ± 1.1% at 5 years and 76.9 ± 6.9% at 7 years. CONCLUSIONS We herein report one of the highest rates of SVD after SAVR with the Trifecta. These data indicate that the durability of the prosthesis decreases at intermediate to long-term follow-up, leading to considerable rates of reintervention due to SVD.

[PMID: 34136565 PMCID: PMC8175165 DOI: 10.1155/2021/3973924] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 05/04/2021] [Accepted: 05/14/2021] [Indexed: 11/18/2022]
Abstract
Aortic stenosis is a disease that is increasing in prevalence and manifests as decreased cardiac output, which if left untreated can result in heart failure and ultimately death. It is primarily a disease of the elderly who often have multiple comorbidities. The advent of transcatheter aortic valve therapies has changed the way we treat these conditions. However, long-term results of these therapies remain uncertain. Recently, there has been an increasing number of studies examining the role of both surgical aortic valve replacement and transcatheter aortic valve replacement. We therefore performed a systematic review using Ovid MEDLINE, Ovid Embase, and the Cochrane Library. Two investigators searched papers published between January 1, 2007, and to date using the following terms: "aortic valve stenosis," "aortic valve operation," and "transcatheter aortic valve therapy." Both strategies in aortic stenosis treatment highlighted specific indications alongside the pitfalls such as structural valve degeneration and valve thrombosis which have a bearing on clinical outcomes. We propose some recommendations to help clinicians in the decision-making process as technological improvements make both surgical and transcatheter therapies viable options for patients with aortic stenosis. Finally, we assess the role of finite element analysis in patient selection for aortic valve replacement. THVT and AVR-S are both useful tools in the armamentarium against aortic stenosis. The decision between the two treatment strategies should be best guided by a strong robust evidence base, ideally with a long-term follow-up. This is best performed by the heart team with the patient as the center of the discussion.

Abstract
Valve-in-Valve transcatheter aortic valve implantation (ViV TAVI) is emerging as an effective therapeutic option for bioprosthetic valve failure. Recently, concern has been raised for early valve deterioration of Mitroflow (Sorin) aortic bioprosthesis, with the development of prevalent stenosis. We report cases of pure severe aortic regurgitation (AR) due to early and mid-term prosthesis degeneration. From June 2018 to October 2019, three patients were treated in our division for the new appearance of severe intraprosthetic regurgitation. Patient 1 (man, 85-year-old) and patient 3 (woman, 83-year-old) had a Mitroflow n. 25 and n. 21 implanted, respectively, in 2012 and 2013 for severe aortic stenosis. Patient 2, a 67-year-old woman with Marfan syndrome underwent a Mitroflow n. 25 implant in 2008 for severe AR and presented chronic type-B aortic dissection. Patient 1 was diagnosed with severe AR in the ambulatory setting, while the other patients presented acute heart failure, requiring inotrope support and high doses intravenous diuretics, and in case 3, temporary extracorporeal ultrafiltration. All patients appeared at high surgical risk and were successfully treated with ViV TAVI, through the right axillary artery in patient 2, and through the femoral artery in patients 1 and 3. Results were good at short- and mid-term follow-up. In conclusion, early and midterm bioprosthesis degeneration with the development of severe AR is a possible complication of the Mitroflow aortic valve. ViV TAVI has been confirmed as a safe and effective therapeutic option in our cases.

Abstract
It is now 50 years since the development of the first pericardial valve in 1971. In this time significant progress has been made in refining valve design aimed at improving the longevity of the prostheses. This article reviews the current literature regarding the longevity of pericardial heart valves in the aortic position. Side by side comparisons of freedom from structural valve degeneration are made for the valves most commonly used in clinical practice today, including stented, stentless, and sutureless valves. Strategies to reduce structural valve degeneration are also discussed including methods of tissue fixation and anti-calcification, ways to minimise mechanical stress on the valve, and the role of patient prosthesis mismatch.

Abstract
OBJECTIVES Some researchers have observed an increased number of deaths during the follow-up of young patients who undergo aortic valve replacement due to severe aortic stenosis, suggesting that this procedure does not restore their life expectancy. Our goal was to confirm these findings and explore sex-based differences. METHODS All patients between 50 and 65 years of age who underwent isolated aortic valve replacement in 27 Spanish centres during an 18-year period were included. We compared observed and expected survival at 15 years of follow-up and estimated the cumulative incidence of death from a competing risks point of view. We stratified by sex and analysed if being a woman was an independent risk factor for death. RESULTS For men, the observed survival at 10 and 15 years of follow-up was 85% [95% confidence interval (CI) 83.6%-86.4%] and 72.3% (95% CI 69.7%-74.7%), respectively whereas the expected survival was 88.1% and 78.8%. For women, the observed survival at 10 and 15 years was 85% (95% CI 82.8%-86.9%) and 73% (95% CI 69.1%-76.4%), whereas the expected survival was 94.6% and 89.4%. At 15 years of follow-up, the cumulative incidence of death due to the disease in men and women was 8.2% and 16.7%, respectively. In addition, being a woman was an independent risk factor for death (hazard ratio = 1.23 (95% CI 1.02-1.48; P = 0.03). CONCLUSIONS After the aortic valve replacement, men and women do not have their life expectancy restored, but this loss is much higher in women than in men. In addition, being a woman is a risk factor for long-term death. Reasons for these findings are unknown and must be investigated.

Abstract
Left sided endocarditis (LSE) can include the entirety or portion of mitral and/or aortic valve and the structures in their anatomical contiguity and represent a significant portion of emergency surgical activity. Literature and guidelines on the management of LSE relies mainly on observational studies given the difficulty in designing randomized trials in emergency settings. Heart teams (HT) are often called in to difficult decisions on the most appropriate strategy to adopted in case of LSE. Decision-making should take into account the localization and the extension of the infection, patient preoperative status and comorbidities, presence of a previous valve prosthesis and best timing for surgery. Despite evidence suggests that early surgery may improve survival in patients with complicated infective endocarditis (IE), an increased risk of recurrence and postoperative valvular dysfunctions has been reported. The most important factors associated with long-term outcomes are preoperative multiorgan failure, prosthetic mechanical valve IE, vegetation size ≥15 mm, and timing of surgical treatment. Importantly, up to one third of potential candidates do not undergo surgery and these patients experience extremely high mortality rates. Another important point regards the choice of the optimal valve substitute to be used according to the different clinical situation. The lack of RCT in this field and the difficulty to design this type of studies in the case of non-elective conditions further complicates the possibility to achieve a univocal consensus on the best strategy to be adopted in each form of LSE and further validation studies are needed. On the basis of the current evidences a decisional algorithm is proposed summarizing all the crucial aspects in the management of LSE.

Abstract
BACKGROUND Clinical studies have demonstrated improved gradients after aortic valve replacement with the Trifecta (TR) valve (Abbott Cardiovascular, St Paul, MN) as compared with the Carpentier-Edwards Magna Ease (ME) valve (Edwards Lifesciences, Irvine, CA). Clinical benefits of this strategy have not been demonstrated. METHODS Patients undergoing aortic valve replacement for severe aortic stenosis with either valve were included. Patients were excluded if they underwent concomitant procedures other than coronary artery bypass grafting. Inverse proportion treatment weighting was used in the analysis. The primary outcome was a composite of cardiac mortality, need for reintervention, and freedom from first congestive heart failure (CHF). Secondary outcomes were all-cause mortality, the composite components, and cumulative CHF admission. Follow-up echocardiograms were assessed in a cohort of patients to assess structural valve degeneration. RESULTS There were 331 patients in the TR group and 360 patients in the ME group. The TR group had more women (48% vs 32%, P < .001) with smaller roots (left ventricular outflow tract diameter: TR, 2.11 cm; ME, 2.17 cm; P < .001). After weighting there was no significant difference in the composite measure between groups (P > .05). There was no difference in all-cause mortality (hazard ratio, 0.82; 95% confidence interval, 0.42-1.59; P = .56), and 5-year survival was 91.9% in the ME group and 93.4% in the TR group. There was no difference in cardiac death, reintervention, or first onset of CHF or incidence of structural valve degeneration between groups. There was no difference in the rate of admissions for CHF per 100 patients between the 2 valve types (P = .19). CONCLUSIONS Early hemodynamic benefits have not translated into differences in medium-term clinical outcomes between these 2 valves. Long-term follow-up is necessary.

Abstract
OBJECTIVES To improve haemodynamic performance, design modifications of prosthetic valves have been proposed with each new generation of valves. These different designs also impact the amount of mechanical wear, because mechanical stresses are distributed differently. Because long-term evidence for new prosthetic valves is lacking, this in vitro study compared hydrodynamic performance and durability among 3 currently available bioprosthetic valves with internally (IMLV) or externally mounted leaflets (EMLV). METHODS Prostheses of the internally mounted Medtronic Avalus and Carpentier-Edwards Perimount Magna Ease valves were compared to prostheses of the externally mounted Abbott Trifecta valve. For each labelled size (e.g. 19, 21 and 23) of the 3 types, 3 valves underwent accelerated wear testing for up to 600 million cycles, corresponding to ∼15 years of simulated wear. The valves underwent hydrodynamic testing and visual inspection. RESULTS EMLV had the largest effective orifice area and lowest pressure gradient for each labelled size at baseline and 600 million cycles; the effective orifice area and the pressure gradient were equivalent for the 2 types of IMLV. Five of 9 EMLVs had at least 1 hole or tear in the leaflet tissue around the stent posts, which resulted in severe regurgitation at 500 million cycles in 2 cases. All IMLVs were intact at 600 million cycles with minimal tissue wear. CONCLUSIONS EMLV showed superior hydrodynamic performance but inferior mechanical durability compared to IMLV after 600 million cycles of testing. The primary failures were because of significant mechanical abrasion in the commissural region, which may warrant close monitoring of EMLV during long-term follow-up.

Abstract
BACKGROUND Asian patients have smaller aortic annuli. Although 20-mm balloon-expandable (BE) transcatheter heart valves (THV) are manufactured for transcatheter aortic valve implantation (TAVI) in these cases, the supra-annular design of self-expandable (SE) THV is considered more suitable; however, real-world comparative data are scarce.Methods and Results:Consecutive TAVI cases (n=330) in a single Japanese center were reviewed. Based on the cutoff for the new-generation 20-/23-mm BE-THV, a small aortic annulus was defined as <330 mm2. A considerable number of patients had small annuli: 49/302 (16%). Of these, 33 BE-THV and 13 SE-THV using new-generation valves were compared. Although the SE-THV group had smaller annulus area (median 297 (interquartile range, 280-313) vs. 309 (303-323) mm2(P=0.022)), it had more favorable post-procedural parameters; for SE-THV and BE-THV, respectively, effective orifice area (EOA), 1.5 (1.3-1.6) vs. 1.1 cm2(0.9-1.3) (P=0.002); mean pressure gradient, 7.6 (5.6-11.0) vs. 14.2 mmHg (11.2-18.8) (P=0.001); and peak velocity, 1.8 (1.6-2.4) vs. 2.7 m/s (2.3-3.1) (P=0.001). Although new left bundle branch block was higher with SE-THV (24% and 62%, P=0.02), patient-prosthesis mismatch (PPM) ≥ moderate (indexed EOA <0.85 cm2/m2) was significantly less with SE-THV than with BE-THV (8% vs. 55%; P=0.04). Hemodynamic findings were consistent up to 1 year. CONCLUSIONS Small annuli are often seen in Asian patients, for whom SE-THV implantation results in favorable hemodynamics with less PPM.

Abstract
Aortic valve replacement is the commonest cardiac surgical operation performed worldwide for infective endocarditis (IE). Long-term durability and avoidance of infection relapse are goals of the procedure. However, no detailed guidelines on prosthesis selection and surgical strategies guided by the comprehensive evaluation of the extension of the infection and its microbiological characteristics, clinical profile of the patient, and risk of infection recurrence are currently available. Conventional mechanical or stented xenografts are the preferred choice for localized aortic infection. However, in cases of complex IE with the involvement of the root or the aortomitral continuity, the use of homograft is suggested according to the surgeon and center experience. Homograft use should be counterbalanced against the risk of structural degeneration. Prosthetic bioroot or prosthetic valved conduit (mechanical and bioprosthetic) are also potentially suitable alternatives. Further development of preservation techniques enabling longer durability of allogenic substitutes is required. We evaluate the current evidence for the use of valve substitutes in aortic valve endocarditis and propose an evidence-based algorithm to guide the choice of therapy. We performed a systemic review to clarify the contemporary surgical management of aortic valve endocarditis.

Abstract
SVD is a main limitation of bioprostheses. Routine use of bioprostheses in younger patients (<60 years of age) is controversial. Data on the durability of surgical aortic bioprostheses beyond 20 years are limited. We report exceptional durability of an aortic bioprosthesis replaced after 25 years.

Abstract
Aortic valve replacement is the most commonly performed cardiac surgical operation worldwide for infective endocarditis (IE). Long-term durability and avoidance of infection relapse are the treatment goals. However, no detailed guidelines on prosthesis selection and surgical strategy are available. Management should be guided by a comprehensive evaluation of infection extension and its microbiological characteristics, the clinical profile of the patient and the risk of infection recurrence. We conducted a literature search of the PubMed database, EMBASE and Cochrane Library (through November 2019) for studies reporting to the use of biological substitutes in aortic valve endocarditis (AVE). Studies comparing long-term outcomes in the use of allogenic and autologous with conventional prostheses were investigated. Conventional mechanical or stented xenografts are the preferred choice for localized aortic infection. In cases of complex IE with the involvement of the root or the aorto-mitral continuity, the use of homografts are recommended, according to surgeon's and center experience. Homograft use needs to be balanced against the risk of structural degeneration. Prosthetic bioroot or prosthetic valved conduit with a mechanical or bioprosthetic valve are acceptable alternatives. The choice of aortic valves substitute and surgical strategy in IE is multifaceted. Principles guiding the selection of prosthesis and surgical approach rely on the long-term durability and the avoidance of infection relapse. A decisional algorithm considering the extension of the infection and its microbiological characteristics, the clinical profile of the patient and the risk of infection recurrence is provided. A multidisciplinary effort is required to achieve consistent outcomes.

Abstract
Background The durability of aortic valve bioprosthesis and the structural valve deterioration (SVD) are could be treated with valve-in-valve (VIV) transcatheter aortic valve implantation (TAVI). This technique has been proven to be a feasible procedure with good results in selected patients. The aim of this work was to assess the long-term results of this TAVI with an autoexpandable valve in patients with failed Mitroflow (MF) bioprosthetic aortic valves. Methods Single center, observational and prospective study that included 65 consecutive patients with symptomatic failed MF bioprosthetic aortic valve, treated with VIV-TAVI. The primary endpoints were clinical long-term events including all-cause mortality, cardiovascular mortality, re-hospitalization due to heart failure, stroke/transient ischemic attack (TIA) and endocarditis. Secondary endpoints were the absence of SVD or patient-prosthesis mismatch (PPM) and valve hemodynamics analysis at follow-up. Results Between March 2012 to July 2019, 65 symptomatic patients (age 80.4±5.9 years) with degenerated MF valves (numbers 19: 27.7%; 21: 38.5%; 23: 21.5%; 25: 12.3%) underwent CoreValve (n=11) or Evolut R (n=54) implantation (23, 26 and 29 mm sizes). The STS predicted risk of mortality was 6.39%±5.62%. The primary combined endpoint occurred in 32.3% of the cases. A total of 13 patients (20%) died during follow-up, but 4 (7.3%) from cardiovascular causes. Two patients were reported of having a stroke/TIA and 5 readmissions for cardiovascular causes were reported (2 of them within the first 30 days). Twenty-five patients (38.5%) presented PPM during follow-up, being PPM severe in 15 (23.1%). Conclusions Self-expanding TAVI for degenerated MF bioprosthesis has favourable long-term outcomes. It is a good option in order to avoid the risks of redo surgery in selected patients.
