Abstract
Transcatheter technologies triggered the recent revision of the guidelines that progressively widened the indications for the treatment of aortic stenosis. On the surgical realm, a technology avoiding the need for sutures to anchor the prosthesis to the aortic annulus has been developed with the aim to reduce the duration of cardiopulmonary bypass and simplify the process of valve implantation. In addition to a transcatheter aortic valve replacement (TAVR)-like stent that exerts a radial force, these so-called "rapid deployment valves" or "sutureless valves" for aortic valve replacement also have cuffs to improve sealing and reduce the risk of paravalvular leak. Despite promising, the actual advantage of sutureless valves over traditional surgical procedures (surgical aortic valve replacement) or TAVR is still debated. This review summarizes the current comparative evidence reporting outcomes of "sutureless valves" for aortic valve replacement to TAVR and surgical aortic valve replacement in the treatment of aortic valve stenosis.

Abstract
Allergy to galactose-α-1,3-galactose (alpha-gal) is associated with immediate allergic manifestations and premature degeneration of the prosthesis in patients who receive bovine- or porcine-derived bioprosthetic valves. Here, we report a 72-year-old man with atrial fibrillation, aortic regurgitation, and severe alpha-gal allergy who presented for consideration of aortic valve replacement. He was premedicated with antihistamines and steroids and underwent aortic valve replacement with 25-mm INSPIRIS aortic valve (Edwards Lifesciences) and left atrial appendage occlusion with 40-mm AtriClip device (AtriCure), without immediate or short-term complications.

Abstract
Bioprosthetic aortic valve thrombosis is frequently detected after transcatheter and surgical aortic valve replacement due to advances in cardiac computed tomography angiography technology and standardized surveillance protocols in low-surgical-risk transcatheter aortic valve replacement trials. However, evidence is limited concerning whether subclinical leaflet thrombosis leads to clinical adverse events or premature structural valve deterioration. Furthermore, there may be net harm in the form of bleeding from aggressive antithrombotic treatment in patients with subclinical leaflet thrombosis. This review will discuss the incidence, mechanisms, diagnosis, and optimal management of bioprosthetic aortic valve thrombosis after transcatheter aortic valve replacement and bioprosthetic surgical aortic valve replacement.

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.

Abstract
BACKGROUND Various bioprosthetic valves are used off-label for pulmonary valve replacement (PVR), but there is no consensus on whether a particular valve is best for this application. Recently, the Inspiris Resilia valve (Edwards Lifesciences Inc) was approved for aortic valve replacement, and surgeons have begun using it for PVR. There is limited evidence on the performance of the Inspiris valve compared with other valves in the pulmonary position. METHODS This study reviewed all patients who underwent PVR with a size 19- to 29-mm Inspiris valve or Mosaic valve (Medtronic Inc) from 2007 to 2022 at Lucile Packard Children's Hospital Stanford (Palo Alto, CA). Midterm outcomes included freedom from moderate or severe pulmonary regurgitation (PR), a maximum Doppler gradient ≥36 mm Hg, and freedom from reintervention. RESULTS A total of 225 consecutive patients who underwent PVR with a size 19- to 29-mm Mosaic (n = 163) or Inspiris (n = 62) valve were included. There was no difference in baseline characteristics. Early postoperative gradients were low in both groups but higher in the Mosaic cohort, and neither group had more than mild PR on discharge. On univariable and multivariable analysis, Inspiris valves were significantly more likely to develop moderate or greater PR over time. There was no significant difference between the valves in freedom from reintervention or from a maximum gradient ≥36 mm Hg. CONCLUSIONS Early and short-term gradients were similar in patients undergoing PVR with Inspiris and Mosaic valves, but significant PR was more common in patients who received an Inspiris valve. These preliminary findings suggest that the durability of the Inspiris valve in the pulmonary position may not be superior to that of other bioprosthetic valves used for PVR.

Three-year outcomes of surgical valve replacement with Dafodil™ pericardial bioprosthesis: Dafodil™-1 trial. Front Cardiovasc Med 2024; 11:1393762. [PMID: 38873269 PMCID: PMC11171715 DOI: 10.3389/fcvm.2024.1393762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 05/07/2024] [Indexed: 06/15/2024] Open
Abstract
Background The Dafodil™-1 trial was designed to evaluate the clinical safety and performance of Dafodil™ pericardial bioprosthesis for replacing diseased native or prosthetic aortic or mitral valves in patients with advanced valvular heart disease (VHD). Methods The Dafodil™-1 trial was a prospective, multicenter, first-in-human clinical trial. Patients were enrolled if they had advanced VHD requiring aortic valve replacement (AVR) or mitral valve replacement (MVR) with or without concomitant valve surgery and having surgical risk scores <4%. Major adverse cardiac events (MACE), including all-cause death, myocardial infarction (MI), and stroke; and hemodynamics were analyzed. Results A total of 136 patients (aortic: 67 and mitral: 69) were enrolled in the trial (with mean age-AVR group: 60.2 ± 8.3 years and MVR group: 49.7 ± 14.4 years). A total of 134 patients (aortic: 66 and mitral: 68) completed the 3-year follow-up (total 300 per 100 patient-years of follow-up). The AVR group demonstrated a significant reduction in the mean pressure gradients from 51.2 ± 24.1 mmHg at baseline to 11.1 ± 6.0 mmHg at the 3-year follow-up (p < 0.0001). The mean effective orifice area (EOA) improved from baseline (0.9 ± 0.6 cm2) to 3-year follow-up (1.8 ± 0.4 cm2) (p < 0.0001). In the MVR group, the mean indexed EOA (iEOA) increased significantly from baseline (0.7 ± 0.4 cm2/m2) to 3-year follow-up (1.1 ± 0.4 cm2/m2) (p < 0.001). There was significant improvement in New York Heart Association functional class and mean SF-12 scores in both groups. At 3-year follow-up, the MACE incidence was 2.3% per 100 patient-years (1.3% strokes per 100 patient-years and 1.3% deaths per 100 patient-years) for AVR group and 4.7% per 100 patient-years (0.6% strokes per 100 patient-years and 4.0% deaths per 100 patient-years) for MVR group. No cases of MI, structural valve deterioration and prosthetic valve endocarditis were reported. The AVR and MVR groups achieved 89.6% and 79.7% MACE-free survival, respectively at 3-year follow-up. Conclusions The Dafodil™-1 trial demonstrated satisfactory outcomes of clinical safety, hemodynamic performance, and quality-of-life metrics. Additionally, no incidence of structural valve deterioration and very low rates of valve thrombosis during the 3-year follow-up period of Dafodil™-1 first-in-human trial indicated acceptable valve durability up to three years and similar outcomes are warranted for longer follow-ups as a primary goal.

Abstract
BACKGROUND Based on the results of a clinical trial in Japan, transcatheter aortic valve replacement (TAVR) for hemodialysis (HD) patients gained approval; however, mid-term TAVR outcomes and transcatheter aortic valve (TAV) durability in HD patients remain unexplored.Methods and Results: We analyzed background, procedural, in-hospital outcome, and follow-up data for 101 HD patients and 494 non-HD patients who underwent TAVR using balloon-expandable valves (SAPIEN XT or SAPIEN 3) retrieved from Osaka University Hospital TAVR database. Periprocedural mortality and TAVR-related complications were comparable between HD and non-HD patients. However, Kaplan-Meier analysis revealed that HD patients had significantly lower survival rates (log-rank test, P<0.001). In addition, HD patients had significantly higher rates of severe structural valve deterioration (SVD) than non-HD patients (Gray test, P=0.038). CONCLUSIONS TAVR in HD patients had comparable periprocedural mortality but inferior mid-term survival and TAV durability than in non-HD patients. Indications for TAVR in younger HD patients should be carefully determined, considering the possibility of a TAV-in-TAV procedure when early SVD occurs.

Real-World Outcomes for the Fifth-Generation Balloon Expandable Transcatheter Heart Valve in the United States. JACC Cardiovasc Interv 2024; 17:1032-1044. [PMID: 38456883 DOI: 10.1016/j.jcin.2024.02.015] [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: 01/17/2024] [Revised: 02/14/2024] [Accepted: 02/14/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND The fifth-generation SAPIEN 3 Ultra Resilia valve (S3UR) incorporates several design changes as compared with its predecessors, the SAPIEN 3 (S3) and SAPIEN 3 Ultra (S3U) valves, including bovine leaflets treated with a novel process intended to reduce structural valve deterioration via calcification, as well as a taller external skirt on the 29-mm valve size to reduce paravalvular leak (PVL). The clinical performance of S3UR compared with S3 and S3U in a large patient population has not been previously reported. OBJECTIVES The aim of this study was to compare S3UR to S3/S3U for procedural, in-hospital, and 30-day clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR). METHODS Patients enrolled in the STS/ACC TVT (Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy) Registry between January 1, 2021, and June 30, 2023, who underwent TAVR with S3UR or S3U/S3 valve platforms were propensity-matched and evaluated for procedural, in-hospital, and 30-day clinical and echocardiographic outcomes. RESULTS 10,314 S3UR patients were propensity matched with 10,314 patients among 150,539 S3U/S3 patients. At 30 days, there were no statistically significant differences in death, stroke, or bleeding, but a numerically higher hospital readmission rate in the S3UR cohort (8.5% vs 7.7%; P = 0.04). At discharge, S3UR patients exhibited significantly lower mean gradients (9.2 ± 4.6 mm Hg vs 12.0 ± 5.7 mm Hg; P < 0.0001) and larger aortic valve area (2.1 ± 0.7 cm2 vs 1.9 ± 0.6 cm2; P < 0.0001) than patients treated with S3/S3U. The 29-mm valve size exhibited significant reduction in mild PVL (5.3% vs 9.4%; P < 0.0001). CONCLUSIONS S3UR TAVR is associated with lower mean gradients and lower rates of PVL than earlier generations of balloon expandable transcatheter heart valve platforms.

Abstract
Infective endocarditis (IE) is a severe cardiac complication with high mortality rates, especially when surgical intervention is delayed or absent. This review addresses the expanding role of surgery in managing IE, focusing on the variation in surgical treatment rates, the impact of patient demographics, and the effectiveness of different surgical approaches. Despite varying global data, a notable increase in surgical interventions for IE is evident, with over 50% of patients undergoing surgery in tertiary centres. This review synthesizes information from focused literature searches up to July 2023, covering preoperative to postoperative considerations and surgical strategies for IE. Key preoperative concerns include accurate diagnosis, appropriate antimicrobial treatment, and the timing of surgery, which is particularly crucial for patients with heart failure or at risk of embolism. Surgical approaches vary based on valve involvement, with mitral valve repair showing promising outcomes compared to replacement. Aortic valve surgery, traditionally favouring replacement, now includes repair as a viable option. Emerging techniques such as sutureless valves and aortic homografts are explored, highlighting their potential advantages in specific IE cases. The review also delves into high-risk groups like intravenous drug users and the elderly, emphasizing the need for tailored surgical strategies. With an increasing number of patients presenting with prosthetic valve endocarditis and device-related IE, the review underscores the importance of comprehensive management strategies encompassing surgical and medical interventions. Overall, this review provides a comprehensive overview of current evidence in the surgical management of IE, highlighting the necessity of a multidisciplinary approach and ongoing research to optimize patient outcomes.

Midterm outcomes of aortic valve replacement using a rapid-deployment valve for aortic stenosis: TRANSFORM trial. JTCVS OPEN 2024; 17:55-63. [PMID: 38420551 PMCID: PMC10897657 DOI: 10.1016/j.xjon.2023.10.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 10/12/2023] [Accepted: 10/26/2023] [Indexed: 03/02/2024]
Abstract
Background The use of rapid-deployment valves (RDVs) has been shown to reduce the operative time for surgical aortic valve replacement (AVR). Long-term core laboratory-adjudicated data are scarce, however. Here we report final 7-year data on RDV use. Methods TRANSFORM was a prospective, nonrandomized, multicenter, single-arm trial implanting a stented bovine pericardial valve with an incorporated balloon-expandable sealing frame. A prior published 1-year analysis included 839 patients from 29 centers. An additional 46 patients were enrolled and implanted, for a total of 885 patients. Annual clinical and core laboratory-adjudicated echocardiographic outcomes were collected through 8 years. Primary endpoints were structural valve deterioration (SVD), all-cause reintervention, all-cause valve explantation, and all-cause mortality. Secondary endpoints included hemodynamic performance assessed by echocardiography. The mean duration of follow-up was 5.0 ± 2.0 years. Results The mean patient age was 73.3 ± 8.2 years. Isolated AVR was performed in 62.1% of the patients, and AVR with concomitant procedures was performed in 37.9%. Freedom from all-cause mortality at 7 years was 76.0% for isolated AVR and 68.2% for concomitant AVR. Freedom from SVD, all-cause reintervention, and valve explantation at 7 years was 97.5%, 95.7%, and 97.8%, respectively. The mean gradient and effective orifice area at 7 years were 11.1 ± 5.3 mm Hg and 1.6 ± 0.3 cm2, respectively. Paravalvular leak at 7 years was none/trace in 88.6% and mild in 11.4%. In patients undergoing isolated AVR, the cumulative probability of pacemaker implantation was 13.9% at 30 days, 15.5% at 1 year, and 21.8% at 7 years. Conclusions AVR for aortic stenosis using an RDV is associated with low rates of late adverse events. This surgical pericardial tissue platform provides excellent and stable hemodynamic performance through 7 years.

Abstract
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. Subgroup meta-analysis was performed to compare Inspiris RESILIA and PERIMOUNT Magna Ease bioprosthesis and to pool the early postoperative mortality and stroke rates. RESULTS A total of 416 studies were identified, of which 15 studies met the eligibility criteria. The studies included a total of 3202 patients with an average follow-up of up to 5.3 years. The average age of patients across the studies was 52.2-75.1 years. Isolated AVR was performed in 39.0-86.4% of patients. In-hospital or 30-day postoperative mortality was 0-2.8%. At the mid-term follow-up, freedom from all-cause mortality was up to 85.4%. Among studies with mid-term follow-up, trace/mild paravalvular leak was detected in 0-3.0%, while major paravalvular leak was found only in up to 2.0% of patients. No statistically significant differences in terms of mortality (P = 0.98, odds ratio 1.02, 95% confidence interval 0.36-2.83) and stroke (P = 0.98, odds ratio 1.01, 95% confidence interval 0.38-2.73) between the Inspiris RESILIA bioprosthesis and PERIMOUNT Magna Ease bioprosthesis were observed in the subgroup meta-analysis. CONCLUSIONS Mid-term data on the safety and haemodynamic performance of the novel aortic bioprosthesis are encouraging. Further comparative studies with other bioprostheses and longer follow-up are still required to endorse durability and safety of the novel bioprosthesis.

Abstract
In the past two decades, transcatheter aortic valve replacement (TAVR) has transformed the management of aortic stenosis and has become the standard of care regardless of surgical risk levels. Advances in transcatheter valve design across newer generations, improved imaging, greater operator expertise, and technical enhancements have collectively contributed to increased safety and a decline in procedural complications over this timeframe. The application of TAVR has progressively expanded to include younger patients with lower risks, who have longer life expectancies. This article offers an up-to-date review of the latest innovations in transcatheter delivery systems, devices, and its possible future indications.

Abstract
OBJECTIVES The short-term performance of the Cingular bovine pericardial aortic valve was proven. This study evaluated its 5-year safety and haemodynamic outcomes. METHODS It enrolled 148 patients who underwent surgical aortic valve replacement with the Cingular bovine pericardial aortic valve between March 2016 and October 2017 in 5 clinical centres in China. Safety and haemodynamic outcomes were followed up to 5 years. The incidence of all-cause mortality, structural valve deterioration and reintervention was estimated by Kaplan-Meier analysis. RESULTS The mean age of patients was 67.7 [standard deviation (SD) 5.1] years, and 36.5% of patients were female. The mean follow-up was 5.3 (SD 1.2) years. Five-year freedom from all-cause mortality, structural valve deterioration and all-cause reintervention were 91.2%, 100% and 99.3%, respectively. At 5 years, the mean gradient and effective orifice area of all sizes combined were 14.0 (SD 5.5) mmHg and 1.9 (SD 0.3) cm2, respectively. For 19- and 21-mm sizes of aortic prostheses, the mean gradients and effective orifice area at 5 years were 17.5 (SD 7.0) mmHg and 1.6 (SD 0.2) cm2 and 13.7 (SD 6.7) mmHg and 1.8 (SD 0.3) cm2, respectively. The incidence of moderate or severe patient-prosthesis mismatch was 4.1% and 0.0% patients at 5 years, respectively. CONCLUSIONS The 5-year safety and haemodynamic outcomes of Cingular bovine pericardial aortic valve are encouraging. Longer-term follow-up is warranted to assess its true durability.

Abstract
BACKGROUND Both valve-sparing root replacement and composite valve graft (CVG) are acceptable options in aortic root replacement. We compare outcomes of these 2 approaches and durability of the aortic valve. METHODS A consecutive 1635 patients without acute dissection underwent primary aortic root replacement from 1997 to 2022; 473 (29%) underwent valve-sparing root replacement, and 1162 (71%) received CVG. Propensity score matching was used to reduce baseline differences. RESULTS The CVG group was older (59 ± 14 years vs 49 ± 14 years; P < .001) with more comorbidities, such as hypertension (88.4% vs 66.4%; P < .001), diabetes (7% vs 1.7%; P < .001), ischemic heart disease (5.1% vs 1.3%; P = .001), pulmonary disease (6.6% vs 1.3%; P < .001), renal impairment (8.6% vs 1.3%; P < .001), class III-IV heart failure (35% vs 9.2%; P < .001), bicuspid aortic valves (44.8% vs 24.1%; P < .001), and severe aortic insufficiency (50.2% vs 13.2%; P < .001). Operative mortality was 0.4% (0% in valve sparing); incidence of major postoperative complications was 2.9% (3.6% vs 1.1%; P = .009). Ten-year survival was 93.1% (91.2% vs 97.7%; hazard ratio [HR], 1.7; 95% CI, 0.9-3.3; P = .120). Mean follow-up was 65 ± 60 months; aortic valve reoperations were similar (5.8% vs 5.7%; HR, 0.8; 95% CI, 0.4-1.4; P = .401). Recurrent moderate-severe aortic insufficiency was less prevalent in CVG (6.1% vs 11.1%; HR, 0.14; 95% CI, 0.07-0.27; P < .001). Propensity score matching identified 225 pairs. There was no difference in 10-year survival or reoperations. Recurrent moderate-severe aortic insufficiency was higher with valve sparing. CONCLUSIONS Both valve-sparing operations and CVG provide excellent early and late outcomes out to 10 years. Valve sparing is associated with a higher risk for development of aortic insufficiency but no difference in reoperations.

Keuffel EL, Reifenberger M, Pellegrini A, Nguyen TC. Savings associated with surgical aortic valve replacement with a RESILIA tissue valve based on seven-year COMMENCE trial results. J Med Econ 2024; 27:910-918. [PMID: 38923952 DOI: 10.1080/13696998.2024.2373001] [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: 05/08/2024] [Accepted: 06/24/2024] [Indexed: 06/28/2024]
Abstract
BACKGROUND Bioprostheses with RESILIA tissue demonstrate a reduction in calcification and improve health outcomes in pre-clinical and clinical studies. Prior economic analyses which relied on 5 years of evidence from the COMMENCE trial demonstrate financial savings for RESILIA tissue valves relative to mechanical valves after surgical aortic valve replacement (SAVR). Given the recent release of 7-year COMMENCE data, this economic evaluation updates the estimate for long-run savings of bioprosthetic valves with RESILIA. METHODS Simulation models estimated disease progression across two hypothetical SAVR cohorts (tissue vs. mechanical) of 10,000 patients each in the US. The primary comparison calculated the SAVR-related expenditures associated with each valve type ($US, 2023). Health outcome probabilities were based on the COMMENCE trial though year 7 and projected for an additional 8 years based on prior studies of tissue and mechanical SAVR. Costs for key outcomes (mortality, reoperation, bleeding, thromboembolism, endocarditis) and anticoagulant monitoring were sourced from the literature. Incidence rates of health outcomes associated with mechanical valves relied on relative risks of tissue valve versus mechanical valve patients. RESULTS Seven-year savings are $13,415 (95% CI = $10,472-$17,321) per patient when comparing RESILIA versus mechanical SAVR. Projected 15-year savings were $23,001 ($US, 2023; 95% CI = $17,802-$30,421). Most of the 15-year savings are primarily attributed to lower anti-coagulation monitoring costs ($21,073 in ACM savings over 15 years), but lower bleeding cost (savings: $2,294) and thromboembolism-related expenditures (savings: $852) also contribute. Reoperation and endocarditis expenditures were slightly larger in the RESILIA cohort. If reoperation relative risk reverts from 1.1 to 2.2 (the level in legacy tissue valves) after year 7, savings are $18,064. RESILIA SAVR also reduce costs relative to legacy tissue valves. CONCLUSION Patients receiving RESILIA tissue valves are projected to have lower SAVR-related health expenditures relative to mechanical and legacy tissue valves.

Long-term outcomes after transcatheter aortic valve replacement: Meta-analysis of Kaplan-Meier-derived data. Catheter Cardiovasc Interv 2023; 102:1291-1300. [PMID: 37890015 DOI: 10.1002/ccd.30854] [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: 07/08/2023] [Revised: 07/23/2023] [Accepted: 10/04/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Transcatheter aortic valve replacement (TAVR) is as an alternative treatment to surgical AVR, but the long-term outcomes of TAVR remain unclear. AIMS This study aimed to analyze long-term outcomes following TAVR using meta-analysis. METHODS A literature search was performed with MEDLINE, EMBASE, Cochrane Library, Web of Science, and Google Scholar through November 2022; studies reporting clinical outcomes of TAVR with follow-up periods of ≥8 years were included. The outcomes of interest were overall survival and/or freedom from structural valve deterioration (SVD). Surgical risk was assessed with the Society of Thoracic Surgeons (STS) predicted risk of mortality (PROM) score. A subgroup analysis was conducted for intermediate-/high-surgical risk patients only. RESULTS Eleven studies including 5458 patients were identified and analyzed. The mean age was 82.0 ± 6.5 years, and mean STS PROM score ranged from 2.9 to 10.6%. Survival rate at 5 and 10 years was 47.7% ± 1.4% and 12.1 ± 2.0%. Five studies including 1509 patients were analyzed for SVD. Freedom from SVD at 5 and 8 years was 95.5 ± 0.7% and 85.1 ± 3.1%. Similar results for survival and SVD were noted in the subgroup analysis of intermediate-/high-risk patients. CONCLUSIONS Following TAVR, approximately 88% of patients died within 10 years, whereas 85% were free from SVD at 8 years. These date suggest that baseline patient demographic have the greatest impact on survival, and SVD does not seem to have a prognostic impact in this population. Further investigations on longer-term outcomes of younger and lower-risk patients are warranted.

Abstract
This review explores the use of bioprosthetic valves for the lifetime management of patients with aortic stenosis, considering recent advancements in surgical (SAV) and transcatheter bioprostheses (TAV). We examine the strengths and challenges of each approach and their long-term implications. We highlight differences among surgical bioprostheses regarding durability and consider novel surgical valves such as the Inspiris Resilia, Intuity rapid deployment, and Perceval sutureless bioprostheses. The impact of hemodynamics on the performance and durability of these prostheses is discussed, as well as the benefits and considerations of aortic root enlargement during Surgical Aortic Valve Replacement (SAVR). Alternative surgical methods like the Ross procedure and the Ozaki technique are also considered. Addressing bioprosthesis failure, we compare TAV-in-SAV with redo SAVR. Challenges with TAVR, such as TAV explantation and considerations for coronary circulation, are outlined. Finally, we explore the potential challenges and limitations of several clinical strategies, including the TAVR-first approach, in the context of aortic stenosis lifetime management. This concise review provides a snapshot of the current landscape in aortic bioprostheses for physicians and surgeons.

Abstract
OBJECTIVES We report 1-year safety and clinical outcomes in patients <60 years undergoing bioprosthetic surgical aortic valve intervention. METHODS The INSPIRIS RESILIA Durability Registry is a prospective, multicentre registry to assess clinical outcomes of patients <60 years. Patients with planned SAVR with or without concomitant replacement of the ascending aorta and/or coronary bypass surgery were included. Time-related valve safety, haemodynamic performance and quality of life (QoL) at 1 year were assessed. RESULTS A total of 421 patients were documented with a mean age of 53.5 years, 76.5% being male and 27.2% in NYHA class III/IV. Outcomes within 30 days included cardiovascular-related mortality (0.7%), time-related valve safety (VARC-2; 5.8%), thromboembolic events (1.7%), valve-related life-threatening bleeding (VARC-2; 4.3%) and permanent pacemaker implantation (3.8%). QoL was significantly increased at 6 months and sustained at 1 year. Freedom from all-cause mortality at 1 year was 98.3% (95% confidence interval 97.1; 99.6) and 81.8% were NYHA I versus 21.9% at baseline. No patient developed structural valve deterioration stage 3 (VARC-3). The mean aortic pressure gradient was 12.6 mmHg at 1 year and the effective orifice area was 1.9 cm2. CONCLUSIONS The 1-year data from the INSPIRIS RESILIA valve demonstrate good safety and excellent haemodynamic performance as well as an early QoL improvement. CLINICAL TRIAL REGISTRATION clinicaltrials.gov: NCT03666741.

Abstract
BACKGROUND There have been few reports on the mid- to long-term safety and efficacy validation of the INSPIRIS RESILIA aortic bioprosthesis (Edwards Lifesciences LLC, Irvine, CA, USA) in Japan. Herein, we report the mid-term results of surgical aortic valve replacement (AVR) for aortic stenosis using INSPIRIS and evaluate the hemodynamics compared to the CEP Magna series from the multicenter AVR registry (the ACTIVIST registry). METHODS Of the 1967 patients who underwent surgical or transcatheter AVR from the ACTIVIST registry, 66 patients who underwent isolated surgical AVR with INSPIRIS by December 2020 were included in this study, and the early and mid-term results were evaluated. Hemodynamics were evaluated by comparing 272 patients undergoing isolated surgical AVR with the Magna group using propensity score matching. RESULTS The mean age was 74.0 ± 7.8 years, and 48.5 % were women. In-hospital mortality was 1.5 %, and the survival rates at 1- and 2-years were 95.2 % and 95.2 %, respectively. After propensity score matching, echocardiographic findings at discharge demonstrated that peak velocity and mean pressure gradient in the INSPIRIS group were comparable, while the effective orifice area in the INSPIRIS group was significantly larger than those in the Magna group (p = 0.048). A patient-prosthesis mismatch at discharge was significantly lower in the INSPIRIS group (11.8 %) than in the Magna group (36.4 %) (p = 0.004). CONCLUSIONS Surgical AVR with INSPIRIS was performed safely and the mid-term results were satisfactory. The hemodynamics of INSPIRIS were comparable to those of Magna.

Abstract
OBJECTIVE As bioprosthetic aortic valve replacement (AVR) extends to younger cohorts, tissue durability is of paramount importance. We report 7-year outcomes from an AVR bioprosthesis utilizing novel tissue. METHODS This was an international investigational device exemption trial for novel AVR with annual follow-up and a subset re-consented at 5 years for extended 10-year follow-up. Safety end points and echocardiographic measurements were adjudicated by an independent clinical events committee and by a dedicated core laboratory, respectively. RESULTS Between January 2013 and March 2016, 689 patients underwent AVR with the study valve. Mean age was 66.9 ± 11.6 years, Society of Thoracic Surgeons risk score was 2.0% ± 1.8%, and 74.3% of patients were New York Heart Association functional class II and III. Five-year follow-up was completed by 512 patients, and 225 re-consented for extended follow-up. Follow-up duration was 5.3 ± 2.2 years (3665.6 patient-years), and 194 and 195 patients completed 6- and 7-year follow-ups, respectively. One-, 5-, and 7-year freedom from all-cause mortality was 97.7%, 89.4%, and 85.4%, respectively. Freedom from structural valve deterioration at 7 years was 99.3%. At 7 years, effective orifice area and mean gradients were 1.82 ± 0.57 cm2 (n = 153), and 9.4 ± 4.5 mm Hg (n = 157), respectively. At 7 years, predominantly none (96.8% [152 out of 157]) or trivial/trace (2.5% [4 out of 157]) paravalvular regurgitation and none (84.7% [133 out of 157]) or trivial/trace (11.5% [18 out of 157]) transvalvular regurgitation were observed. CONCLUSIONS We report the longest surgical AVR follow-up with novel tissue in an investigational device exemption trial utilizing an independent clinical events committee and an echocardiography core laboratory. This tissue demonstrates excellent outcomes through 7 years and is the benchmark for future surgical and transcatheter prostheses.

Abstract
Objective Novel tissue leaflets (RESILIA tissue) may improve durability of bioprosthetic heart valves. The COMMENCE trial is an ongoing prospective study to evaluate valve replacement using RESILIA tissue. This report describes mid-term outcomes in the mitral cohort of COMMENCE. Methods Adult patients requiring mitral valve replacement were enrolled in a prospective, single-arm trial at 17 sites in the United States and Canada. An independent clinical events committee adjudicated safety events using definitions from established guidelines, and hemodynamic performance was evaluated by an independent echocardiographic core laboratory. Results Eighty-two patients (median age 70 years) successfully underwent mitral valve replacement with the study valve. Five-year event-free probabilities for all-cause mortality, structural valve deterioration, and reoperation were 79.9%, 98.7%, and 97.1%, respectively. Hemodynamic valve function measurements were stable through the 5-year follow-up period; valvular leaks were infrequently observed and primarily clinically insignificant/mild. Conclusions Mitral valve replacement patients implanted with a RESILIA tissue bioprosthesis had a good safety profile and clinically stable hemodynamic performance.

One-year clinical outcomes following Edwards INSPIRIS RESILIA aortic valve implantation in 487 young patients with severe aortic stenosis: a single-center experience. Front Cardiovasc Med 2023; 10:1196447. [PMID: 37600038 PMCID: PMC10435896 DOI: 10.3389/fcvm.2023.1196447] [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: 03/29/2023] [Accepted: 06/26/2023] [Indexed: 08/22/2023] Open
Abstract
Introduction The use of an aortic bioprosthesis is on the rise in younger patients with severe aortic stenosis despite the risk of accelerated structural valve degeneration (SVD). In the search for an optimal valve substitute that would not be prone to SVD, the INSPIRIS bioprosthesis represents a promising solution to lowering the risk of SVD. Here, we report the 1-year outcomes of the INSPIRIS RESILIA aortic bioprosthesis in a population of young patients who underwent aortic valve replacement. Methods In this prospective single-center study, we included all consecutive patients receiving INSPIRIS RESILIA bioprosthesis between June 2017 and July 2021. Patients with isolated severe aortic regurgitation were excluded. Clinical assessment and transthoracic echocardiography were performed preoperatively and at 1 year post-operatively. The primary outcome was overall mortality at one year. Results A total of 487 patients were included. The mean age was 58.2 ± 11.5 years, 75.2% were men. Most of the interventions were elective, with a mean EuroSCORE II of 4.8 ± 7.9. The valve annulus size in most cases was either 23 mm or 25 mm. Overall mortality at 1-year was 4.1%. At 1-year, 7 patients (1.4%) had a stroke, 4 patients (0.8%) had a myocardial infarction, and 20 patients (4.1%) were hospitalized for congestive heart failure. The Kaplan-Meier estimated survival rates and survival without major adverse cardiac events at 1-year were 96.4% and 96.7%, respectively. At 1-year follow-up, 10 patients (2.1%) had endocarditis and 1 patient (0.2%) had partial prosthetic thrombosis. Pacemaker implantation at 1-year post-operative was necessary in 27 patients (5.5%). Severe patient prosthesis mismatch and severe intra valvular regurgitation were 1.2% and 0.6%, respectively. The Kaplan-Meier estimated survival rates at 1-year of no infective endocarditis preoperative and infective endocarditis preoperative were 97.9 ± 0.7% and 89.5 ± 3.3%, respectively (P < 0.001). Excluding endocarditis-related complication, no structural valve deterioration and no valve failure requiring redo surgery were reported. Conclusion This is the largest single-center descriptive study of the 1-year outcomes after INSPIRIS RESILIA bioprosthesis implantation. The EDWARDS INSPIRIS RESILIA bioprosthesis provides encouraging clinical outcomes with an excellent 1- year survival rates and good hemodynamic performance. Long-term studies are mandatory to assess valve durability.

Mid-term clinical and echocardiographic results of the INSPIRIS RESILIA aortic valve: a retrospective comparison to the Magna Ease. INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2023; 37:ivad117. [PMID: 37462610 PMCID: PMC10386877 DOI: 10.1093/icvts/ivad117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 06/12/2023] [Accepted: 07/17/2023] [Indexed: 07/30/2023]
Abstract
OBJECTIVES The INSPIRIS aortic valve combines the RESILIA proprietary tissue preservation process and an expandable stent frame to benefit future transcatheter valve-in-valve procedures. As the INSPIRIS valve became commercially available in 2017, mid-term outcome reports are scarce. We aimed to evaluate mid-term safety and echocardiographic performance of the INSPIRIS valve in comparison to its predecessor, the Carpentier Edwards Perimount Magna Ease (ME). METHODS This study was a retrospective single-centre study. Clinical results included early postoperative outcomes, mid-term mortality and readmission for cardiovascular cause or stroke. Echocardiographic follow-up (FU) was performed at discharge and 1-3, 6, 12 and 24 months. Clinical end point analyses were accomplished with a propensity score matching analysis and FU echocardiographic data comparisons using pairwise analyses and linear mixed-effect models. RESULTS We included 953 patients who received an INSPIRIS (n = 488) or ME (n = 463) bioprosthesis between January 2018 and July 2021. In the matched population (n = 217 per group), no significant difference in short-term outcomes was observed, survival was similar at 30 months (INSPIRIS: 94% vs ME: 91%, P = 0.89), but freedom from readmission was higher in the INSPIRIS group (94% vs 86%, P = 0.014). INSPIRIS valves had a lower gradient at discharge (∼10 vs 14 mmHg, P < 0.001), 1-3 months (∼10 vs 12 mmHg, P < 0.001) and 24 months (∼11 vs 17 mmHg, P < 0.001) in paired analyses and significantly lower evolution of mean transvalvular gradients compared to ME. CONCLUSIONS This study represents the largest comparative evaluation of the INSPIRIS to the ME valves, which demonstrated safe clinical outcomes and favourable haemodynamic performance at 2 years. Long-term FU is underway.

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
INTRODUCTION Transcatheter aortic valve implantation (TAVI) is the standard of care for selected patients with severe aortic stenosis, irrespective of the surgical risk. Over the last two decades of TAVI practice, multiple limitations were identified. In addition, the extension of TAVI into a wider patient spectrum created new challenges. AREAS COVERED This review provides an overview of emerging transcatheter heart valves (THVs) beyond the approved contemporary THVs for the treatment of aortic stenosis. EXPERT OPINION The incidence of degenerative aortic stenosis is expected to increase with more aging of the population. Therefore, TAVI needs to meet this increase in the number of patients indicated for aortic valve replacement alongside a wide and complex anatomical variability. An increasing number of Aortic THVs are available in the market. This includes upgraded iterations of contemporary devices and innovative devices developed by emerging manufacturers. The new devices aim for the reduction or elimination of undesirable outcomes like paravalvular leakage and conduction disturbances requiring permanent pacemaker implantation. Alternatively, emerging THVs should provide feasibility regarding yet unproven TAVI indications like Bicuspid aortic valve, aortic regurgitation, or very large anatomy. Furthermore, some of the emerging THVs are designed to tackle the long-term durability issue of biological valves.

Abstract
Modern cardiac surgery has rapidly evolved to treat complex cardiovascular disease. This past year boasted noteworthy advances in xenotransplantation, prosthetic cardiac valves, and endovascular thoracic aortic repair. Newer devices often offer incremental design changes while demanding significant cost increases that leave surgeons to decide if the benefit to patients justifies the increased cost. As innovations are introduced, surgeons must continuously aim to harmonize short- and long-term benefits with financial costs). We must also ensure quality patient outcomes while embracing innovations that will advance equitable cardiovascular care.

Abstract
BACKGROUND The Inspiris Resilia (Edwards Lifesciences LLC) bioprosthesis has gained widespread use in the aortic position; however no robust data are available about its use in the pulmonary position. METHODS We reviewed our outcomes for the Inspiris Resilia in the pulmonary position between August 2019 and October 2021. RESULTS Twenty-seven patients (15 female patients [56%]; mean age, 22.26 ± 14.99 years) were included. The most common original pathology was tetralogy of Fallot (13 patients, 48%). Five patients (18.5%) had prior transcatheter interventions. The mean right ventricular end-diastolic volume index was 164.25 ± 45.1 mL/m2. Sternotomy or repeat sternotomy was the most common approach (21 patients, 77.8%). The standard technique for pulmonary valve replacement was used in 22 patients (81.5%), whereas the prosthesis was implanted as a conduit in the remaining 5 (18.5%). Trivial to mild prosthetic regurgitation was present in 6 patients (22.2%) at the time of discharge. There was no early mortality. Follow-up was complete in all patients (mean, 16 ± 8 months), with no late mortality or late reoperations. New prosthetic regurgitation developed in 13 patients (48%), all of whom underwent replacement with the standard surgical technique. No regurgitation occurred in the conduit cases. This progressed to moderate regurgitation in 6 patients (22%) and severe in 3 (11%). Three patients (11%) underwent transcatheter valve-in-valve after their surgical pulmonary valve replacement. CONCLUSIONS The early data regarding the Inspiris Resilia bioprosthesis use in the pulmonary position is concerning. The prosthesis design may not be suitable for low-pressure circulation, or modification of its implantation technique may be needed.

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
Aim: Durability of aortic valve replacement is becoming increasingly important. Aortic bioprostheses with RESILIA tissue have demonstrated outstanding outcomes thus far, but only in single-arm studies. Methods: We compared structural valve deterioration (SVD)-related hemodynamic valve deterioration (HVD) of grade ≥2 of RESILIA tissue valves from the COMMENCE trial (n = 689) to those from the PARTNER 2A contemporary AVR arm (n = 936) based upon annual core laboratory echocardiograms through 5 years of follow-up. Results: SVD-related HVD in the COMMENCE and PARTNER 2A cohorts were 1.8 versus 3.5%, respectively (one-sided 95% lower-bound hazard ratio of 0.92; p = 0.07). In propensity-matched cohorts (n = 239), these outcomes were 1.0 versus 4.8%, respectively (one-sided 95% lower-bound hazard ratio of 1.15; p = 0.03). Conclusion: RESILIA tissue-based AVR exhibited reduced SVD-related HVD compared with a contemporary AVR cohort devoid of RESILIA tissue.

Abstract
BACKGROUND Prior economic analyses demonstrate that legacy tissue valves are associated with substantial financial savings over the long run after a surgical aortic valve replacement (SAVR). Bioprostheses with RESILIA tissue reduce calcification, the primary cause of structural valve deterioration (SVD), and have demonstrated promising pre-clinical and 5-year clinical results. This economic evaluation quantifies the expected long-run savings of bioprosthetic valves with RESILIA tissue relative to mechanical valves given 5-year clinical results and expected performance through year 15. METHODS Simulation models estimated disease progression across two hypothetical SAVR cohorts (tissue vs. mechanical) of 10,000 patients in the US over 15 years. One comparison evaluated RESILIA tissue valves relative to mechanical valves. The other compared legacy SAVR tissue and mechanical valves. Health outcome probabilities and costs were based on literature and expert opinion. Incidence rates of health outcomes associated with mechanical valve were calculated using relative risks of expected outcomes in tissue valve versus mechanical valve patients. The comparisons also accounted for anti-coagulation monitoring in both cohorts. Savings estimates are based on US healthcare costs and do not yet account for the premium associated use of RESILIA relative to a standard tissue valve. RESULTS Relative to mechanical SAVR, the median net discounted savings for a patient receiving SAVR with a RESILIA tissue valve is $20,744 ($US, 2020; 95% CI = $15,835-$26,655) over a 15-year horizon. While 30-day and 1-year savings were not significant, expected savings after 5 years are $9,110 (95% CI = $6,634-$11,969). Net savings for RESILIA SAVR valves were approximately 30-50% larger than savings anticipated using legacy tissue SAVR valves. CONCLUSION RESILIA tissue valves are associated with lower health expenditures relative to mechanical valves.

Abstract
Since the first groundbreaking procedure in 2002, transcatheter aortic valve implantation (TAVI) has revolutionized the management of aortic stenosis (AS). Through striking developments in pertinent equipment and techniques, TAVI has now become the leading therapeutic strategy for aortic valve replacement in patients with severe symptomatic AS. The procedure streamlining from routine use of conscious sedation to a single arterial access approach, the newly adapted implantation techniques, and the introduction of novel technologies such as intravascular lithotripsy and the refinement of valve-bioprosthesis devices along with the accumulating experience have resulted in a dramatic reduction of complications and have improved associated outcomes that are now considered comparable or even superior to surgical aortic valve replacement (SAVR). These advances have opened the road to the use of TAVI in younger and lower-risk patients and up-to-date data from landmark studies have now established the outstanding efficacy and safety of TAVI in patients with low-surgical risk impelling the most recent ESC guidelines to propose TAVI, as the main therapeutic strategy for patients with AS aged 75 years or older. In this article, we aim to summarize the most recent advances and the current clinical aspects involving the use of TAVI, and we also attempt to highlight impending concerns that need to be further addressed.

Abstract
Aortic stenosis is a common form of acquired degenerative valvular disease associated with poor survival after the onset of symptoms. Treatment options for patients with aortic stenosis in addition to medical therapy include surgical aortic valve replacement (SAVR) with either tissue or mechanical valves, or transcatheter aortic valve replacement (TAVR) with either balloon-expandable or self-expanding valves via either transfemoral or alternative access routes. In this review, the authors discuss the current evidence and special considerations regarding the use of TAVR versus SAVR in the management of severe aortic stenosis in young (<65 years of age), low-risk patients, highlighting the history of aortic stenosis treatment, the current guidelines and recommendations, and important issues that remain to be addressed. Ultimately, until ongoing clinical trials with long-term follow-up data shed light on whether interventions for aortic stenosis can be broadened to a low-risk population, TAVR in young, low-risk patients should be undertaken with caution and with guidance from a multidisciplinary heart team.

Surgical aortic valve replacement with a stented pericardial bioprosthesis: 5-year outcomes. Eur J Cardiothorac Surg 2022; 62:6631229. [PMID: 35789382 PMCID: PMC9346377 DOI: 10.1093/ejcts/ezac374] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 04/21/2022] [Accepted: 07/04/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES This analysis evaluated the safety, durability, and haemodynamic performance of a stented bovine pericardial valve through 5 years of follow-up in patients with an indication for surgical aortic valve replacement (SAVR). METHODS Kaplan-Meier analysis was used to estimate the incidence of survival and valve-related thromboembolism, major paravalvular leak (PVL), endocarditis, structural valve deterioration (SVD), and reintervention. Mean aortic gradient and New York Heart Association (NYHA) class were also evaluated. RESULTS 1118 patients have received the Avalus valve (Medtronic); 564 have completed 5-year follow-up. Median follow-up was 4.85 years (4810 patient-years total follow-up). At baseline, mean age was 70.2 ± 9.0 years; 75.1% of patients were male. STS predicted risk of mortality was 2.0 ± 1.4%. Most patients were in NYHA class II (46.8%) or III (40.3%). At 5 years follow-up, the overall Kaplan-Meier survival rate was 88.1% (85.9-90.0%). The Kaplan-Meier event rates were 5.6% (4.3-7.2%) for thromboembolism, 4.4% (3.2-6.0%) for endocarditis, 0.2% (0.0-0.7%) for major PVL, and 3.2% (2.3-4.6%) for reintervention. There were no cases of SVD. Mean gradient decreased from 42.1 ± 17.1 mmHg at baseline, to 13.1 ± 4.7 mmHg at discharge, and remained stable at 12.5 ± 4.6 mmHg at 5 years. More than 95% of patients were in NYHA class I/II 5 years after surgery. CONCLUSIONS The findings of a high survival rate, excellent safety, no SVD, and stable haemodynamic performance and functional status through 5 years of follow-up are encouraging. Additional follow-up is needed to assess the long-term durability of this contemporary surgical bioprosthesis.

Budget impact analysis of a bioprosthetic valve with a novel tissue versus mechanical aortic valve replacement in patients older than 65 years with aortic stenosis in Saudi Arabia.

Abstract
AIMS A budget impact analysis (BIA) comparing bioprosthetic valves with RESILIA tissue and mechanical valves in aortic stenosis (AS) patients > 65 years in the public and private sectors of Saudi Arabia. MATERIALS AND METHODS A decision-tree with a partitioned survival model was adapted to estimate the financial consequences of either a RESILIA tissue valve or a mechanical valve in aortic valve replacement (AVR) procedures up to 5 years. The budget impact of resource consumption for both valve types was compared and included disabling strokes, reoperations, minor thromboembolic events, major bleeding, endocarditis, anticoagulation treatment and monitoring, and echocardiogram assessments. One-way sensitivity analyses (OWSA) were performed on cost and probability inputs. RESULTS RESILIA tissue valves versus mechanical valves are overall budget saving commencing in Year 1 and savings gradually increase year-on-year. The higher costs of the initial procedure, reoperation, and additional monitoring (echocardiogram tests and visits) associated with RESILIA tissue valves are offset by savings in warfarin use, disabling strokes, major bleeding, and anticoagulation complications. The cost per initial procedure per patient is SAR795 higher for a RESILIA tissue valve reflecting the higher valve acquisition cost, which is partially offset by a shorter hospital stay. The OWSA suggests that total procedure costs of each valve, including the hospital stay, are the main cost drivers in the model. LIMITATIONS The variability of cost inputs and the presence of multiple payers with multiple costing data is a key challenge in Saudi Arabia. Budget impact results may, therefore, change if repeated per AVR center and may also be impacted by the long-term durability of RESILIA tissue valves. CONCLUSIONS An AVR in patients > 65 years with a RESILIA tissue valve is budget-saving from the first year in Saudi Arabia. Patients, payers, providers and policymakers may benefit economically from increased implantation of RESILIA tissue valves.
