Abstract
Valvular heart disease (VHD) has become a burden and a growing public health problem in humans, causing significant morbidity and mortality worldwide. An increasing number of patients with severe VHD need to undergo heart valve replacement surgery, and artificial heart valves are in high demand. However, allogeneic valves from donors are lacking and cannot meet clinical practice needs. A mechanical heart valve can activate the coagulation pathway after contact with blood after implantation in the cardiovascular system, leading to thrombosis. Therefore, bioprosthetic heart valves (BHVs) are still a promising way to solve this problem. However, there are still challenges in the use of BHVs. For example, their longevity is still unsatisfactory due to the defects, such as thrombosis, structural valve degeneration, calcification, insufficient re-endothelialization, and the inflammatory response. Therefore, strategies and methods are needed to effectively improve the biocompatibility and longevity of BHVs. This review describes the recent research advances in BHVs and strategies to improve their biocompatibility and longevity.

J Thorac Cardiovasc Surg 2024; 167:1705-1713.e8. [PMID: 36404144 DOI: 10.1016/j.jtcvs.2022.10.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 10/12/2022] [Accepted: 10/13/2022] [Indexed: 11/11/2022]
Abstract
OBJECTIVES PERIMOUNT Magna Ease (Carpentier-Edwards; PME) prostheses have been widely implanted during the past decade for aortic valve replacement (AVR). Although promising results at midterm follow-up were reported, long-term outcome has yet to be confirmed. On this study we aimed to evaluate long-term results in terms of structural valve degeneration (SVD), major clinical outcomes, long-term hemodynamic valve performance, and left ventricular remodeling. METHODS From 2010 to 2012, 689 consecutive patients underwent AVR with PME. Complete clinical 10-year follow-up was obtained. The degree of SVD was categorized on the basis of the latest guidelines. Echocardiographic data were analyzed at 1, 5, and 10 years. Competing risk analysis was performed for major events. Cumulative incidence of SVD, reoperation, and endocarditis were also assessed according to prosthetic sizes (19-21-23 mm vs 25-27-29 mm) and age (<65 vs 65-75 vs >75 years old). RESULTS The overall cumulative incidence reported for SVD ≥2 and reoperation were 3.6% and 1.9% at 10 years, respectively. An early left ventricular reverse remodeling was noted after implantation and confirmed at follow-up. Patients younger than 65 years showed higher cumulative incidence of SVD ≥2 at 10 years compared with patients aged 65 to 75 and older than 75 years (9.7% vs 2.6% vs 2.7%; P = .013), as well as of redo AVR (7.8% vs 3.3% vs 0.4%; P = .002). There was no difference in terms of SVD and redo AVR for different prosthetic size categories (P > .05). The risk of endocarditis was similar among age and size groups. CONCLUSIONS PME provides very good durability at long-term and could be considered one of the high performing third-generation bioprostheses for AVR.

An exploratory cost-effectiveness analysis of a novel tissue valve compared with mechanical valves for surgical aortic valve replacement in subgroups of people aged 55-64 and 65+ with aortic stenosis in the UK. Expert Rev Pharmacoecon Outcomes Res 2023; 23:1087-1099. [PMID: 37638585 DOI: 10.1080/14737167.2023.2249611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 08/14/2023] [Indexed: 08/29/2023]
Abstract
OBJECTIVE Exploratory analysis to conceptualize and evaluate the potential cost-effectiveness and economic drivers of using a novel tissue valve compared with mechanical heart valves for surgical aortic valve replacement (SAVR) in people aged 55-64 and 65+ with aortic stenosis (AS) from a National Health Service (NHS) UK perspective. METHODS A decision-analytic model was developed using a partitioned survival model. Parameter inputs were obtained from published literature. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were conducted to explore the uncertainty around the parameters. RESULTS The novel tissue valve was potentially associated with higher quality-adjusted life years (QALYs) of 0.01 per person. Potential cost savings were greatest for those aged 55-64 (£408) versus those aged 65+(£53). DSA indicated the results to be most dependent on relative differences in general mortality, procedure costs, and reoperation rates. PSA estimated around 75% of the iterations to be cost-effective at £20,000 per QALY for those aged 55-64, and 57% for those aged 65+. CONCLUSIONS The exploratory analysis suggests that the novel tissue valve could be a cost-effective intervention for people over the age of 55 with AS who are suitable for SAVR in the UK.

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.

Perimount MAGNA Ease vs. INSPIRIS Resilia Valve: A PS-Matched Analysis of the Hemodynamic Performances in Patients below 70 Years of Age. J Clin Med 2023; 12:jcm12052077. [PMID: 36902862 PMCID: PMC10004583 DOI: 10.3390/jcm12052077] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 02/23/2023] [Accepted: 03/04/2023] [Indexed: 03/09/2023] Open
Abstract
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). Propensity score (PS) matching was performed by logistic regression with adjustment for eight key baseline variables. The two prostheses were compared in terms of hemodynamic performances up to 3 years postoperatively. Sub-analysis according to prosthetic size-category was accomplished. RESULTS A total of 122 pairs with similar baseline characteristics were obtained from the PS-matching. The two prostheses showed comparable hemodynamic performances at one year (Gmean: 11.3 ± 3.5 mmHg vs. 11.9 ± 5.4 mmHg; p = 0.8) and at 3 years postoperatively (Gmean: 12.2 ± 7.9 mmHg vs. 12.8 ± 5.2 mmHg for; p = 0.3). The sub-analysis of size-category confirmed no statistical differences concerning the hemodynamic performances for each annulus size. CONCLUSIONS This first PS-matched analysis demonstrated that the newly developed IR valve achieves the same safety and efficacy of the PME valve during mid-term follow-up in patients aged <70 years.

Abstract
BACKGROUND Infective endocarditis (IE) is a rare disease with a high mortality rate. Leclercia adecarboxylata (L. adecarboxylata) is a movable Gram-negative bacillus of enterobacteriaceae, and it can rarely be a pathogen which often affects immunodeficient patients. There are about three cases of immunocompetent patients with monomicrobial L. adecarboxylata infection. There are only three reported cases of IE caused by L. adecarboxylata in the world. The mitral valve is often affected in IE, and the prognosis for IE with mitral valve lesions is often poor.
CASE SUMMARY A 51-year-old man was found to have moderate to severe mitral stenosis on echocardiography. He came to our Cardiothoracic Surgery Department for surgical management. A diastolic murmur was heard on auscultation of the heart in the mitral region. On the second day of hospitalisation, he presented with slurred speech, reduced muscle strength in the left limb, and acute cerebral infarction on cranial computed tomography. Surgical treatment was decided to postpone. On the ninth day of admission, the patient developed a sudden high fever and shock and was transferred to the Cardiac Intensive Care Unit, where echocardiogram revealed an anterior mitral valve leaflet vegetation. After empirical anti-infective treatment with vancomycin (1g q12h), an emergency valve replacement was performed. Bacterial culture identified L. adecarboxylata. Anti-infective treatment with piperacillin-tazobactam (4.5g q8h) was added for 4 wk. Follow-up echocardiography showed normal bioprosthetic valve function after mitral valve replacement.
CONCLUSION We report the first case of L. adecarboxylata IE in China, and clinicians should pay attention to this pathogen.

Abstract
Background Aortic valve neocuspidization (AVNeo) has emerged as a promising aortic valve procedure, and is expected to have a larger effective orifice area (EOA) than commercially available bioprostheses. It is, however, unclear which indices could facilitate left ventricular (LV) reverse remodeling after AVNeo. The aim of this study is to verify the impact of global left ventricular afterload on the LV reverse remodeling following AVNeo. Methods Data-available consecutive 38 patients (median age, 77; interquartile range, 72.8–82.0) undergoing AVNeo for severe aortic stenosis were enrolled in this study. Preoperative and the last follow-up echocardiographic data were retrospectively analyzed including the valvuloarterial impedance (Zva), a marker of global LV afterload. Reduction in LV geometry index (LVGI) and relative wall thickness (RWT) were used as an indicator for LV reverse remodeling. Results The Zva reduced in 24 patients (63.2%) during the follow-up period (median, 12 months). Reduction in Zva significantly correlated to improvement of LV geometry (LVGI (r = 0.400, p = 0.013) and RWT (r = 0.627, p < 0.001)), whereas increase in EOA index did not significantly correlate to LVGI (r = 0.009, p = 0.957), or RWT (r = 0.105, p = 0.529)). The reduction in Zva was the multivariate predictor of LV reverse remodeling. Conclusions Low global LV afterload led to significant LV reverse remodeling even after AVNeo, which could achieve better valve performance than the conventional bioprostheses.

Adv Ther 2021; 38:2435-2446. [PMID: 33788152 PMCID: PMC8010499 DOI: 10.1007/s12325-021-01705-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 03/10/2021] [Indexed: 11/25/2022]
Abstract
Introduction Aortic valve replacement (AVR) via right anterior mini-thoracotomy (RAMT) is less traumatic than via other surgical routes; using a novel aortic valve may confer long-term resistance against valve deterioration, and thus be useful in younger, more active patients. Here we aim to validate using the INSPIRIS RESILIA valve with minimally invasive RAMT. Methods Between April 2017 and June 2019, 100 patients underwent video-assisted minimally invasive AVR by RAMT, using the INSPIRIS RESILIA aortic valve. Cannulation for cardiopulmonary bypass (CPB) was through femoral vessels. Clinical data were prospectively entered into our institutional database. Results Cardiopulmonary bypass (CPB) and cross-clamping times were 79 ± 38 and 41 ± 17 min. Surgical access was successful in 100% of cases. There were no cases of intraoperative mortality, 30-day mortality, cerebrovascular events, rethoracotomy for bleeding, valve-related reoperation, right internal mammary artery injury, or conversion to sternotomy. Intensive care and hospital stays were 2 ± 1 and 6 ± 3 days, respectively. One patient had a pacemaker fitted. Postoperative dialysis was necessary in one patient. Trace to mild aortic valve regurgitation occurred in two patients. No structural valve deterioration (SVD) and paravalvular leak were seen. At 1-year follow-up mean effective orifice area (EOA) was 1.8 ± 0.1 cm2, peak gradient was 22.1 ± 3.1 mmHg, and mean gradient was 11.5 ± 2.3 mmHg. Conclusion Our preliminary experience suggests that RAMT for AVR using the INSPIRIS RESILIA aortic valve is safe, effective, and reproducible. Larger studies are needed to evaluate the long-term efficacy and durability of this new valve.

Abstract
BACKGROUND The Carpentier-Edwards Perimount valves have a proven track record in aortic valve replacement: good durability, hemodynamic performance, rates of survival, and low rates of valve-related complications and prosthesis-patient mismatch. The St. Jude Medical Trifecta is a newer valve that has shown comparable early and midterm outcomes. Studies show reoperation rates of Trifecta are comparable with Perimount valves, with a few recent studies bringing into focus early structural valve deterioration (SVD), and increased midterm SVD in younger patients. Given that midterm data for Trifecta is still sparse, we wanted to confirm the early low reoperation rates of Trifecta persist over time compared with Perimount. METHODS The Maritime Heart Centre Database was searched for AVR between 2011 and 2016, inclusive. The primary endpoint of the study was all-cause reoperation rate. RESULTS In total, 711 Perimount and 453 Trifecta implantations were included. The reoperation hazards were determined for age: 0.96 (0.92-0.99; p = .02), female (vs. male): 0.35 (0.08-1.53; p = .16), smoker (vs. nonsmoker): 2.44 (0.85-7.02; p = .1), and Trifecta (vs. Perimount): 2.68 (0.97-7.39; p = .06). Kaplan-Meier survival analysis in subgroups-age <60, age ≥60, male, female, smoker, and nonsmoker-showed Perimount having lower reoperation rates than Trifecta in patients younger than 60 (p = .02) and current smokers (p < .01). CONCLUSIONS The rates of reoperation of Perimount and Trifecta were comparable, with Trifecta showing higher rates in patients younger than 60 years, and current smokers. Continued diligence and further independent reporting of midterm reoperation and SVD rates of the Trifecta, including detailed echocardiographic follow-up, are needed to confirm these findings.

Abstract
BACKGROUND Despite being rare, infective endocarditis (IE) is a life-threatening disease with poor prognosis. New diagnostic and therapeutic strategies are emerging; however, predisposing factors and microbiology of the disease are also changing with time. Because of this, there has been a lack of reduction in the disease's incidence and new challenges for clinicians have arisen such as an increasingly aging population and growing antimicrobial resistance. AIMS In this paper, we aim to provide an overview of the changing trends in IE, current diagnosis, and management strategies, as well as the emerging role of the infective endocarditis teams in the care of patients with this disease. MATERIALS & METHODS A comprehensive electronic search was done utilizing PubMed, Ovid, SCOPUS, Embase and google scholar. The search terms included 'Endocarditis', 'IE', 'Infection', 'Vegetation', 'Duke criteria', 'native valve infection', 'prosthetic valve', 'valve infection', 'endocarditis outcome' and 'endocarditis bacteriology'. The references of the identified articles were then searched for any potential articles that can be included. The inclusion criteria were any article that discussed the evidence behind incidence and management of IE including the role of endocarditis team. The exclusion criteria were case reports, expert opinion, and editorials. RESULTS All the relevant findings are summarized in specified tables and within appropriate sections. DISCUSSION It is vital to determine the current trends in the epidemiology and microbiology of the condition so that the diagnostic threshold can be adapted, to identify new at-risk groups and achieve an accelerated evaluation strategy that allows for earlier diagnosis and treatment. CONCLUSION Management of IE can benefit from the input of different specialties, such as cardiology, cardiothoracic surgery, infectious disease, and microbiology. Therefore, adopting a multidisciplinary approach towards treatment is crucial to reduce morbidity and mortality from preventable complications of this pathology.
