Abstract
The mechanical valve was first invented in the 1950s, and since then, a wide variety of prostheses have been developed. Although mechanical valves have outstanding durability, their use necessitates life-long treatment with anticoagulants, which increases the risk of bleeding and thromboembolic events. The current guidelines recommend a mechanical prosthetic valve in patients under 50-60 years; however, for patients aged 50-70 years, the data are conflicting and there is not a clear-cut recommendation. In recent decades, progress has been made in several areas. First, the On-X mechanical valve was introduced; this valve has a lower anticoagulant requirement in the aortic position. Second, a potential alternative to vitamin K-antagonist treatment, rivaroxaban, has shown encouraging results in small-scale trials and is currently being tested in a large randomized clinical trial. Lastly, an innovative mechanical valve that eliminates the need for anticoagulant therapy is under development. We attempted to review the current literature on the subject with special emphasis on the role of mechanical valves in the current era and discuss alternatives and future innovations.

Abstract
Aortic insufficiency (AI) is a valvular disease with increasing prevalence in older patients. The modern era provides numerous options for the management of AI which is explored here. Traditional interventions included aortic valve replacement with either mechanical or bioprosthetic aortic valves. While the former is known for its durability, it has grown out of favor due to the potential complications of anticoagulation. The preference for bioprosthetic valves is thus on the rise, especially with the advancements of transcatheter technology and the use of valve-in-valve therapy. Surgical options are also no longer limited to replacement but include complex techniques such as those required for aortic valve repair, Ozaki neocuspidization, Ross procedure and valve-sparring aortic root repair. Transcatheter options for the management of AI are not commercially available currently; however, preliminary data from ad-hoc trials, showed promising results and potential use of transcatheter technology in a variety of patients with pure AI.

Abstract
BACKGROUND Decellularized pulmonary homografts are being increasingly adopted for right ventricular outflow tract reconstruction in adult patients undergoing the Ross procedure. Few reports presented Matrix PplusN xenograft (Matrix) in a negative light. The objective of this study was to compare our midterm outcomes of Matrix xenograft versus standard cryopreserved pulmonary homograft (CPHG). METHODS Eighteen patients received Matrix xenograft between January 2012 and June 2016, whereas 66 patients received CPHG. Using nonparametric statistical tests and survival analysis, we compared midterm echocardiographic and clinical outcomes between the groups. RESULTS Except for significant age difference (the Matrix group was significantly older with 57 ± 8 years than the CPHG group, 48 ± 9 years, p = 0.02), the groups were similar in all other baseline characteristics. There were no significant differences in cardiopulmonary bypass times (208.3 ± 32.1 vs. 202.8 ± 34.8) or in cross-clamp times (174 ± 33.9 vs. 184.4 ± 31.1) for Matrix and CPHG, respectively. The Matrix group had significantly inferior freedom from reintervention than the CPHG group with 77.8 versus 98.5% (p = 0.02). Freedom from pulmonary valve regurgitation ≥ 2 was not significantly different between the groups with 82.4 versus 90.5% for Matrix versus CPHG, respectively. After median follow-up of 4.9 years, Matrix xenograft developed significantly higher peak pressure gradients compared with CPHG (20.4 ± 15.5 vs. 12.2 ± 9.0 mm Hg; p = 0.04). CONCLUSION After 5 years of clinical and echocardiographic follow-up, the decellularized Matrix xenograft had inferior freedom from reintervention compared with the standard CPHG. Closer follow-up is necessary to avoid progression of valve failure into right ventricular deterioration.

Abstract
OBJECTIVE To describe long-term outcomes of the Ross procedure in a single center and retrospective series after 25 years follow-up. METHODS From 1997-2019 we included all consecutive patients who underwent Ross procedure at our center. Clinical and echocardiographic evaluations were performed at least yearly. Echocardiographic valvular impairment was defined as at least moderate autograft or homograft dysfunction. Reintervention outcomes included surgical and percutaneous approach. RESULTS 151 Ross procedures were performed (mean age 28±12years, 21 %<16years, 70 %male). After 25 years follow-up (median 18 years, interquartile range 9-21, only 3 patients lost) 12 patients died (8 %); Autograft, homograft or any valve dysfunction were present in 38(26 %), 48(32 %) and 75(51 %), respectively; and reintervention in 22(15%), 17(11%) and 38(26 %) respectively. At 20 years of follow-up, probabilities of survival free from autograft, homograft or any valve dysfunction were 63 %, 60 % and 35 %; and from reintervention, 80 %, 85 % and 67 %, respectively. The learning curve period (first 12 cases) was independently associated to autograft dysfunction (HR 2.78, 95 %CI:1.18-6.53, p = 0.02) and reintervention (HR 3.76, 95 %CI: 1.46-9.70, p = 0.006). Larger native pulmonary diameter was also an independent predictor of autograft reintervention (HR 1.22, 95 %CI:1.03-1.45, p = 0.03). Homograft dysfunction was associated with younger age (HR 5.35, 95 %CI: 2.13-13.47, p<0.001) and homograft reintervention, with higher left ventricle ejection fraction (HR 1,10, 95 %CI:1.02-1.19, p<0.02). CONCLUSIONS In this 25 years' experience after the Ross procedure, global survival was high, although autograft and homograft dysfunction and reintervention rates were not negligible. Clinical and echocardiographic variables can identify patients with higher risk of events in follow up.

J Clin Med 2024; 13:630. [PMID: 38276135 PMCID: PMC10816914 DOI: 10.3390/jcm13020630] [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: 11/02/2023] [Revised: 11/30/2023] [Accepted: 12/05/2023] [Indexed: 01/27/2024] Open
Abstract
The Ross procedure is gaining recognition as a significant option for aortic valve replacement (AVR), and is particularly beneficial in specific patient groups. Although categorized as a class IIb recommendation in the 2020 American College of Cardiology (ACC)/American Heart Association (AHA), and the European Society of Cardiology (ESC) management guidelines on valvular heart disease, recent studies bolster its credibility. Research, including a propensity-matched study, underlines the Ross procedure's association with enhanced long-term survival and reduced adverse valve-related events compared to other AVR types. This positions the Ross procedure as a primary option for AVR in young and middle-aged adults within specialized centers, and potentially the only choice for children and infants requiring AVR. This review meticulously examines the Ross procedure, covering historical perspectives, surgical techniques, imaging, and outcomes, including hemodynamic performance and quality of life, especially focusing on pediatric and young adult patients. It explores contemporary techniques and innovations like minimally invasive approaches and tissue engineering, underscoring ongoing research and future directions. A summarization of comparative studies and meta-analyses reiterates the Ross procedure's superior long-term outcomes, valve durability, and preservation of the left ventricular function, accentuating the crucial role of patient selection and risk stratification, and pinpointing areas for future research.

Long-Term Outcomes of Ross Procedure versus Mechanical Aortic Valve Replacement: Meta-Analysis of Reconstructed Time-To-Event Data. Trends Cardiovasc Med 2024; 34:29-36.

Abstract
In the era of lifetime management of aortic valve disease, the Ross procedure emerged as an alternative to prosthetic heart valves for young adults; however, more long-term data are warranted. We performed a meta-analysis of reconstructed time-to-event data to compare long-term outcomes between the Ross procedure and mechanical aortic valve replacement (mAVR) in young adults. PubMed/MEDLINE, EMBASE and GoogleScholar were searched for studies comparing Ross procedure with mAVR that reported mortality/survival rates and/or reoperation rates accompanied by at least one Kaplan-Meier curve for any of the outcomes. Six observational studies (5 with propensity score matching) including 5024 patients (Ross: 1737; mAVR: 3287) met our inclusion criteria. Patients who underwent Ross had a significantly lower risk of mortality in the overall population (HR 0.38, 95%CI 0.30-0.49, P<0.001; median follow-up of 7.2 years) and in the propensity score matched cohorts (HR 0.55, 95%CI 0.42-0.73, P<0.001; median follow-up of 10.2 years); however, the incidence function for the cumulative risk of reoperation was higher for the Ross procedure (HR 1.91, 95%CI 1.36-2.70, P<0.001; median follow-up of 9.3 years). Data from observational studies suggest that the Ross procedure is associated with lower all-cause mortality compared with mAVR; however, there is a higher risk of reoperation. Besides serving as basis to inform patients about benefits and risks involved in this choice, these results call for further randomized clinical trials to determine whether the Ross procedure can achieve its potential benefits in young patients in need of AVR.

Abstract
Background The science of dissemination and implementation (D&I) aims to improve the quality and effectiveness of care by addressing the challenges of incorporating research and evidence-based practice into routine clinical practice. This lens of D&I has challenged the interpretation and incorporation of data, noting that failure of a given therapy may not reflect lack of efficacy, but instead reflect an imperfect implementation. The aim of this manuscript is to review the influence of the Ross procedure's historical context on its D&I. Methods A contextual baseline of the Ross procedure was defined from the procedure's original description in the literature to major publications since the 2017 valvular heart disease guidelines. D&I evaluation was conducted using the Consolidated Framework for Implementation Research (CFIR), using constructs from each of the five respective domains to define the main determinants. Results Each of the five CFIR domains appears to be correlated with a factor influencing the Ross procedure's varied history of enthusiasm and acceptance. The complex nature of Ross required adaptation for optimization, with a strong correlation of center volume on outcomes that were not considered in non-contemporary studies. Outcomes later published from those studies influenced social and cultural contexts within the aortic surgery community, and led to further organizational uncertainty, resulting in slow guideline incorporation. Conclusions The D&I of the Ross procedure was a result of inadequate appreciation of technical complexity, effect of patient selection, and complex aortic surgery experience, resulting in dismissal of an efficacious procedure due to a misunderstanding of effectiveness.

Abstract
OBJECTIVES There are several treatment options for non-elderly adults (18-60 years) in need of aortic valve replacement (AVR): a mechanical or biological substitute, a homograft, the Ross procedure or nowadays even transcatheter aortic valve replacement. This study evaluated the current opinions and practices of cardiac surgeons and cardiologists concerning AVR strategies in this patient group. METHODS A 43-item online survey was sent out to several scientific organizations, individual cardiac surgeons, cardiologists and residents/fellows worldwide. RESULTS Two hundred twenty-two physicians from 33 different countries answered the survey. The UK (24%), Belgium (23%) and North America (22%) are best represented. A mechanical valve is the most frequently used substitute in non-elderly. With increasing patient age, the popularity of a biological valve increases. Transcatheter aortic valve replacement and the Ross procedure are each used in <10% of this cohort. Only 12% of the cardiac surgeons has experience with the Ross surgery. In 23%, the patient seems not to be involved in the decision on the type of valve substitute. CONCLUSIONS The preferred surgical treatment for non-elderly patients in need of AVR differs widely. To enable a shared decision-making process including patient preferences, there is more need for collaboration between cardiac departments, as well as education and scientific research about patient-centred outcomes of the different AVR techniques.

Abstract
The pulmonary autograft in the Ross procedure, where the aortic valve is replaced by the patient's own pulmonary valve, is prone to failure due to dilatation. This is likely caused by tissue degradation and maladaptation, triggered by the higher experienced mechanical loads in aortic position. In order to further grasp the causes of dilatation, this study presents a model for tissue growth and remodeling of the pulmonary autograft, using the homogenized constrained mixture theory and equations for immuno- and mechano-mediated mass turnover. The model outcomes, compared to experimental data from an animal model of the pulmonary autograft in aortic position, show that inflammation likely plays an important role in the mass turnover of the tissue constituents and therefore in the autograft dilatation over time. We show a better match and prediction of long-term outcomes assuming immuno-mediated mass turnover, and show that there is no linear correlation between the stress-state of the material and mass production. Therefore, not only mechanobiological homeostatic adaption should be taken into account in the development of growth and remodeling models for arterial tissue in similar applications, but also inflammatory processes.

Abstract
BACKGROUND Although, valve sparing is commonly performed in patients with Marfan syndrome, feasibility and results of cusp repair for aortic insufficiency have not been studied. AIM To report on the outcomes and durability of aortic cusp repair in valve sparing in patients with Marfan syndrome. METHODS All consecutive adult patients with Marfan syndrome who underwent remodelling and annuloplasty with aortic valve repair for aortic insufficiency between May 2005 and December 2020 were included. Patients with Marfan syndrome treated for aortic aneurysm, but without aortic insufficiency, were excluded. Data were collected prospectively and reviewed retrospectively from the Aorticvalve repair International Registry (AVIATOR). RESULTS During the study period, 71 patients with Marfan syndrome were referred to surgery. Fifty-five patients with connective tissue disease and aortic insufficiency with aorta aneurysm were treated: 46 underwent aortic valve repair and nine underwent aortic valve replacement (five mechanical aortic valve replacements and four biological aortic valve replacements). The mean age was 42.9±15.4 years, and the mean EuroScore II was 2.5±2.2. No patient died, and no patient had significant aortic insufficiency (grade≥II) at discharge. The 5-year survival rate estimate was 94.4%, which seems statistically similar to that of the age- and sex-matched general population. At 5 years, freedom from reoperation was 94.6%, and the incidence of infective endocarditis was 2.6%. No valve thrombosis, aortic dissection, major bleeding events, thromboembolic events (stroke) or myocardial infarctions were noted during follow-up. CONCLUSION Remodelling and aortic valve repair showed excellent durability at 5 years, even in connective tissue disorders.

Abstract
BACKGROUND There has been a resurgence in interest regarding the Ross procedure due to recent publications detailing positive long-term outcomes. Conversely, surgical aortic valve replacement (SAVR) with a pulmonary homograft (PH), mechanical (MV), bioprosthetic (BV), or the Ozaki procedure each has its own technical advantages and disadvantages. Therefore, we performed a network meta-analysis (NMA) comparing other alternatives to Ross procedure. METHODS Medical databases were comprehensively searched for studies comparing the Ross procedure with AVR using a PH, MV, BV, or the Ozaki procedure. Outcomes were pooled as risk ratios (RR) with their 95% confidence intervals (95% CI). RESULTS A total of 7816 patients were pooled for our NMA from 24 studies. Compared to Ross procedure, both BV and MV were associated with significantly higher rates of 30-day mortality of RR (2.37, 95% CI 1.20-4.67) and (1.88 95% CI 1.04-3.40), respectively, with no significant difference regarding PH or Ozaki. However, only MV was associated with a higher risk of 30-day stroke (RR 8.42, 95% CI 1.57-45.23) with no significant difference in the other alternatives, as well as 30-day MI which showed no significant differences between any of the aortic conduits compared to the Ross procedure. Regarding 30-day major bleeding, MV was associated with a higher when compared to the Ross procedure RR (4.58, 95% CI 1.94-10.85), PH was associated with a lower risk of major bleeding with RR (0.35, 95% CI 0.17-0.71), and BV showed no significant difference. With a mean follow-up duration of 8.5 years compared to the Ross procedure, BV, PH, and MV were associated with a higher risk of long-term mortality with RR (1.89, 95% CI 1.38-2.58), (1.38, 95% CI 1.0-1.87), and (1.94, 95% CI 1.52-2.47), respectively, with the Ozaki procedure showed no significant difference. Regarding long-term stroke-with a mean of 6.3-year follow-up duration-there were no significant differences between any of the aortic conduits compared to the Ross procedure. Nevertheless, long-term need for reintervention-with a mean follow-up duration of 17.5 years-was significant of higher risk with both BV and PH with RR (3.28, 95% CI 1.21-8.84) and (2.42, 95% CI 1.05-5.58), respectively, compared to Ross procedure with MV and Ozaki having no significant difference. CONCLUSIONS The Ross procedure is a viable treatment option for patients undergoing SAVR, showing promising outcomes at short- and long-term follow-ups.

Abstract
Valvular heart disease is a globally prevalent cause of morbidity and mortality, with both congenital and acquired clinical presentations. Tissue engineered heart valves (TEHVs) have the potential to radically shift the treatment landscape for valvular disease by functioning as life-long valve replacements that overcome the current limitations of bioprosthetic and mechanical valves. TEHVs are envisioned to meet these goals by functioning as bioinstructive scaffolds that guide the in situ generation of autologous valves capable of growth, repair, and remodeling within the patient. Despite their promise, clinical translation of in situ TEHVs has proven challenging largely because of the unpredictable and patient-specific nature of the TEHV and host interaction following implantation. In light of this challenge, we propose a framework for the development and clinical translation of biocompatible TEHVs, wherein the native valvular environment actively informs the valve's design parameters and sets the benchmarks by which it is functionally evaluated.

Abstract
OBJECTIVE The inclusion technique was developed to reinforce the pulmonary autograft to prevent dilation after the Ross procedure. Anticommissural plication (ACP), a modification technique, can reduce graft size and create neosinuses. The objective was to evaluate pulmonary valve biomechanics using the inclusion technique in the Ross procedure with and without ACP. METHODS Seven porcine and 5 human pulmonary autografts were harvested from hearts obtained from a meat abattoir and from heart transplant recipients and donors, respectively. Five additional porcine autografts without reinforcement were used as controls. The Ross procedure was performed using the inclusion technique with a straight polyethylene terephthalate graft. The same specimens were tested both with and without ACP. Hemodynamic parameter data, echocardiography, and high-speed videography were collected via the ex vivo heart simulator. RESULTS Porcine autograft regurgitation was significantly lower after the use of inclusion technique compared with controls (P < .01). ACP compared with non-ACP in both porcine and human pulmonary autografts was associated with lower leaflet rapid opening velocity (3.9 ± 2.4 cm/sec vs 5.9 ± 2.4 cm/sec; P = .03; 3.5 ± 0.9 cm/sec vs 4.4 ± 1.0 cm/sec; P = .01), rapid closing velocity (1.9 ± 1.6 cm/sec vs 3.1 ± 2.0 cm/sec; P = .01; 1.8 ± 0.7 cm/sec vs 2.2 ± 0.3 cm/sec; P = .13), relative rapid opening force (4.6 ± 3.0 vs 7.7 ± 5.2; P = .03; 3.0 ± 0.6 vs 4.0 ± 2.1; P = .30), and relative rapid closing force (2.5 ± 3.4 vs 5.9 ± 2.3; P = .17; 1.4 ± 1.3 vs 2.3 ± 0.6; P = .25). CONCLUSIONS The Ross procedure using the inclusion technique demonstrated excellent hemodynamic parameter results. The ACP technique was associated with more favorable leaflet biomechanics. In vivo validation should be performed to allow direct translation to clinical practice.

Abstract
OBJECTIVE There is uncertainty about surgical procedures for adult patients aged 18-60 years undergoing aortic valve replacement (AVR). Options include conventional AVR (mechanical, mAVR; tissue, tAVR), the pulmonary autograft (Ross) and aortic valve neocuspidisation (Ozaki). Transcatheter treatment may be an option for selected patients. We used formal consensus methodology to make recommendations about the suitability of each procedure. METHODS A working group, supported by a patient advisory group, developed a list of clinical scenarios across seven domains (anatomy, presentation, cardiac/non-cardiac comorbidities, concurrent treatments, lifestyle, preferences). A consensus group of 12 clinicians rated the appropriateness of each surgical procedure for each scenario on a 9-point Likert scale on two separate occasions (before and after a 1-day meeting). RESULTS There was a consensus that each procedure was appropriate (A) or inappropriate (I) for all clinical scenarios as follows: mAVR: total 76% (57% A, 19% I); tAVR: total 68% (68% A, 0% I); Ross: total 66% (39% A, 27% I); Ozaki: total 31% (3% A, 28% I). The remainder of percentages to 100% reflects the degree of uncertainty. There was a consensus that transcatheter aortic valve implantation is appropriate for 5 of 68 (7%) of all clinical scenarios (including frailty, prohibitive surgical risk and very limited life span). CONCLUSIONS Evidence-based expert opinion emerging from a formal consensus process indicates that besides conventional AVR options, there is a high degree of certainty about the suitability of the Ross procedure in patients aged 18-60 years. Future clinical guidelines should include the option of the Ross procedure in aortic prosthetic valve selection.

Abstract
Background The Ross operation appears to restore normal survival in young and middle-aged adults with aortic valve disease. However, there are limited data comparing it with conventional aortic valve replacement. Herein, we compared outcomes of the Ross procedure with mechanical and bioprosthetic aortic valve replacement (M-AVR and B-AVR, respectively). Methods and Results MEDLINE and EMBASE were searched through March 2022 to identify randomized controlled trials and propensity score-matched studies that investigated outcomes of patients aged ≥16 years undergoing the Ross procedure, M-AVR, or B-AVR. The systematic literature search identified 2 randomized controlled trials and 8 propensity score-matched studies involving a total of 4812 patients (Ross: n=1991; M-AVR: n=2019; and B-AVR: n=802). All-cause mortality was significantly lower in the Ross procedure group compared with M-AVR (hazard ratio [HR] [95% CI], 0.58 [0.35-0.97]; P=0.035) and B-AVR (HR [95% CI], 0.32 [0.18-0.59]; P<0.001) groups. The reintervention rate was lower after the Ross procedure and M-AVR compared with B-AVR, whereas it was higher after the Ross procedure compared with M-AVR. Major bleeding rate was lower after the Ross procedure compared with M-AVR. Long-term stroke rate was lower following the Ross procedure compared with M-AVR and B-AVR. The rate of endocarditis was also lower after the Ross procedure compared with B-AVR. Conclusions Improved long-term outcomes of the Ross procedure are demonstrated compared with conventional M-AVR and B-AVR options. These results highlight a need to enhance the recognition of the Ross procedure and revisit current guidelines on the optimal valve substitute for young and middle-aged patients.

Abstract
Background The ideal aortic valve replacement strategy in young‐ and middle‐aged adults remains up for debate. Clinical practice guidelines recommend mechanical prostheses for most patients less than 50 years of age undergoing aortic valve replacement. However, risks of major hemorrhage and thromboembolism associated with long‐term anticoagulation may make the pulmonary autograft technique, or Ross procedure, a preferred approach in select patients. Methods Data were retrospectively collected for patients 18–50 years of age who underwent either the Ross procedure or mechanical aortic valve replacement (mAVR) between January 2000 and December 2016 at a single institution. Propensity score matching was performed and yielded 32 well‐matched pairs from a total of 216 eligible patients. Results Demographic and preoperative characteristics were similar between the two groups. Median follow‐up was 7.3 and 6.9 years for Ross and mAVR, respectively. There were no early mortalities in either group and no statistically significant differences were observed with respect to perioperative outcomes or complications. Major hemorrhage and stroke events were significantly more frequent in the mAVR population (p < .01). Overall survival (p = .93), freedom from reintervention and valve dysfunction free survival (p = .91) were equivalent. Conclusions In this mid‐term propensity score‐matched analysis, the Ross procedure offers similar perioperative outcomes, freedom from reintervention or valve dysfunction as well as overall survival compared to traditional mAVR but without the morbidity associated with long‐term anticoagulation. At specialized centers with sufficient expertize, the Ross procedure should be strongly considered in select patients requiring aortic valve replacement.

Abstract
Background Unicuspid aortic valve (UAV) is the second most common underlying cause of aortic valve dysfunction in young adults after the bicuspid valve. The valve may be replaced (for example by pulmonary autograft) or repaired using the bicuspidization technique. The aim of our study was to compare short- and mid-term outcomes of Ross procedure with bicuspidization in patients with severe UAV dysfunction. Methods This was a multi-center retrospective observational cohort study comparing data from two dedicated Ross centers in the Czech Republic with bicuspidization outcomes provided by AVIATOR registry. As for the Ross group, only the patients with UAV were included. Primary endpoint was mid-term freedom from reintervention. Secondary endpoints were mid-term freedom from major adverse events, endocarditis and pacemaker implantation. Results Throughout the study period, 114 patients underwent the Ross procedure (years 2009-2020) and 126 patients underwent bicuspidization (years 2006-2019). The bicuspidization group was significantly younger and presented with a higher degree of dyspnea, a lower degree of aortic valve stenosis and more often with pure regurgitation. The primary endpoint occurred more frequently in the bicuspidization group than in the Ross group – 77.9 vs. 97.9 % at 5 years and 68.4 vs. 75.2 % at 10 years (p < 0.001). There was no difference in secondary endpoints. Conclusion Ross procedure might offer a significantly lower mid-term risk of reintervention than bicuspidization in patients with UAV. Both procedures have comparable survival and risk of other short- and mid-term complications postoperatively.

Abstract
BackgroundThe Ross procedure is recommended as an optimal aortic valve replacement (AVR) in children and young adults due to several advantages. Nevertheless, multiple reconstructions of the right ventricular outflow tract (RVOT) with new valve conduits have caused some concern regarding the durability of the Ross AVR. Decellularized bovine jugular vein conduit (BJVC) (DP-BJVC) and hand-sewn expanded polytetrafluoroethylene valved conduits (ePTFE VC) are widely employed to reconstruct the RVOT with satisfactory long-term outcomes. However, few studies have compared the safety and efficacy between the two valve conduits. We aimed to evaluate the early outcomes and report our single center experience in the application of these conduits.MethodsTwenty-two pediatric patients (aged < 18 years) who underwent Ross procedures with DP-BJVC and ePTFE VC in our center between 1 June, 2017 and 31 January, 2022 were enrolled. The Kaplan–Meier method was used to evaluate survival, freedom from RVOT reintervention, and freedom from RVOT graft dysfunction. Mixed-effects analysis with the Geisser–Greenhouse correction and Sidak's multiple comparisons test for post-hoc analysis was employed to compare the peak gradient across the conduit at varying follow-ups.ResultsAll patients were followed up in full. The total early survival rate was 90.9%; two patients in the DP-BJVC group died. There was no significant difference in early mortality, cross-clamp time (p = 0.212), in-hospital stay (p = 0.469), and RVOT graft thrombosis or endocarditis between the two groups. There was similarly no significant difference between Kaplan–Meier freedom from RVOT graft dysfunction curve (P = 0.131). The transprosthetic gradient gradually increased over time in both groups and was significantly higher in the DP-BJVC group at follow-up (P < 0.05).ConclusionsBoth conduits show excellent early and midterm outcomes for RVOT reconstruction in the Ross procedure. We suggest that DP-BJVC is more suitable for infants, and ePTFE conduit is more suitable for older children who require larger conduits.

Abstract
The ideal aortic valve substitute in young adults remains unknown. Prosthetic valves are associated with a suboptimal survival and carry a significant risk of valve-related complications in young patients, mainly reinterventions with tissue valves and, thromboembolic events and major bleeding with mechanical prostheses. The Ross procedure is the only substitute that restores a survival curve similar to that of a matched general population, and permits a normal life without functional limitations. Though the risk of reintervention is the Achilles' heel of this procedure, it is very low in patients with aortic stenosis and can be mitigated in patients with aortic regurgitation by tailored surgical techniques. Finally, the Ozaki procedure and the transcatheter aortic valve implantation are seen by many as future alternatives but lack evidence and long-term follow-up in this specific patient population.

Abstract
OBJECTIVES This study aimed to provide an in-depth insight into our single-centre experience with the Ross procedure. METHODS All adults who underwent the Ross procedure between 1991 and 2014 were included. Based on the total number of Ross procedures performed by each surgeon at our centre during this 24-year period, surgeon volume was classified as low (<25 procedures), intermediate (25-44 procedures), and high (≥45 procedures). Survival, complications and reinterventions were evaluated. A single cardiologist assessed the pulmonary autograft's function and the neoaortic root diameter by echocardiography. RESULTS The outcomes of 224 patients [176 men, 48 women; mean age 37.2 (standard deviation 10.0) years] were analysed. Patients operated on by a low-volume surgeon had 7.22 times higher odds (P < 0.001) for a serious adverse event during the intraoperative or early postoperative course than patients operated on by a high-volume surgeon. Early mortality was 1.8%. Overall survival was 87.3% at 20 years. Compared with the demographically matched general population, the patients' survival was significantly lower (P = 0.002). The cumulative incidence of autograft and right ventricular outflow tract conduit reintervention was 21.5% and 5.9% at 20 years, respectively. Patients with preoperative aortic regurgitation had 6.25 times the subdistribution hazard of autograft reintervention (Bonferroni-adjusted P = 0.042) and a higher neoaortic root z-score [1.37 (standard deviation 2.04) versus 0.17 (standard deviation 1.81), P = 0.004] than patients with aortic stenosis. In patients with preoperative aortic regurgitation, autograft wrapping (remnant aortic wall and/or Vicryl® mesh) was associated with a 74% reduction in the subdistribution hazard of autograft reintervention (Bonferroni-adjusted P = 0.002) and with a reduced incidence of neoaortic root dilatation (P = 0.037). CONCLUSIONS The Ross procedure performed by a specialized surgeon provides very satisfying long-term results. The higher risk of autograft reintervention in preoperative aortic regurgitation may be counteracted by supporting the autograft.

Abstract
Background Gray matter volume (GMV) alteration in specific brain regions has been widely regarded as one of the most important neuroplasticity features in chronic pain patients with depressive symptoms (CP-D). However, the consistent and significant results were still lacking. Thus, further exploration was suggested to be performed. Objectives This study aimed to comprehensively collect the voxel-based morphometry (VBM) studies on GMV alteration between CP-D and healthy controls (HCs). And a systemic review and meta-analysis were made to explore the characteristic brain regions in chronic pain and depression comorbidity. Methods Search of PubMed, MEDLINE, Web of Science, and Cochrane Library databases updated to July 13, 2021. The altered GMV between CP-D and HCs in VBM studies was included in this meta-analysis. In total, 18 studies (20 datasets) and 1320 participants (520 patients and 800 HCs) were included. The significant coordinate information (x, y, z) reported in standard space and the effect size (t-value or z-score) were extracted and analyzed by anisotropic effect size-signed differential mapping (AES-SDM) 5.15 software. Results According to the main analysis results, CP-D showed significant and consistent increased GMV in the left hippocampus (HIP. L) and decreased GMV in the medial part of the left superior frontal gyrus (SFG. L, BA 10) compared to HCs. Subgroup analysis showed significant decreased GMV in the medial orbital part of SFG.R (BA 10) in neuropathic pain, as well as significant increased GMV in the right parahippocampal gyrus (PHG.R, BA 35), left hippocampus (HIP.L, BA 20), and right middle frontal gyrus (MFG.R) in musculoskeletal pain. Furthermore, meta-regression showed a positive relationship between the decreased GMV in the medial part of SFG.L and the percentage of female patients. Conclusion GMV abnormality in specific brain areas (e.g., HIP.L and SFG) was robust and reproducible, which could be significantly involved in this comorbidity disease. The findings in this study may be a valuable reference for future research. Systematic Review Registration [www.crd.york.ac.uk/prospero/].

Abstract
BACKGROUND The ideal aortic valve substitute for young and middle-aged adults remains elusive. OBJECTIVES This study sought to compare the long-term outcomes of patients undergoing the Ross procedure and those receiving bioprosthetic aortic valve replacements (AVRs). METHODS Consecutive patients aged 16-60 years who underwent a Ross procedure or surgical bioprosthetic AVR at the Toronto General Hospital between 1990 and 2014 were identified. Propensity score matching was used to account for differences in baseline characteristics. The primary outcome was all-cause mortality. Secondary outcomes included valve reintervention, valve deterioration, endocarditis, thromboembolic events, and permanent pacemaker implantation. RESULTS Propensity score matching yielded 108 pairs of patients. The median age was 41 years (IQR: 34-47 years). Baseline characteristics were similar between the matched groups. There was no operative mortality in either group. Mean follow-up was 14.5 ± 7.2 years. All-cause mortality was lower following the Ross procedure (HR: 0.35; 95% CI: 0.14-0.90; P = 0.028). Using death as a competing risk, the Ross procedure was associated with lower rates of reintervention (HR: 0.21; 95% CI: 0.10-0.41; P < 0.001), valve deterioration (HR: 0.25; 95% CI: 0.14-0.45; P < 0.001), thromboembolic events (HR: 0.15; 95% CI: 0.05-0.50; P = 0.002), and permanent pacemaker implantation (HR: 0.22; 95% CI: 0.07-0.64; P = 0.006). CONCLUSIONS In this propensity-matched study, the Ross procedure was associated with better long-term survival and freedom from adverse valve-related events compared with bioprosthetic AVR. In specialized centers with sufficient expertise, the Ross procedure should be considered the primary option for young and middle-aged adults undergoing AVR.

Abstract
BACKGROUND There has recently been renewed interest in the Ross procedure in adults. OBJECTIVES The goal of this study was to compare long-term outcomes after the Ross procedure vs biological and mechanical aortic valve replacement (AVR) in adults (aged 18-50 years) undergoing aortic valve surgery. METHODS Mandatory California and New York databases were queried between 1997 and 2014. Exclusion criteria included: ≥1 concomitant procedure, reoperations, infective endocarditis, intravenous drug use, hemodialysis, and out-of-state residency. Propensity matching (1:1:1) was used, resulting in 434 patients per group. The primary endpoint was all-cause mortality. Secondary endpoints were stroke, major bleeding, reoperation, and endocarditis. Median follow-up was 12.5 years (IQR: 9.3-15.7 years). RESULTS At 15 years, actuarial survival after the Ross procedure was 93.1% (95% CI: 89.1%-95.7%), similar to that of the age-, sex-, and race-matched U.S. general population. It was significantly lower after biological AVR (HR: 0.42; 95% CI: 0.23-0.075; P = 0.003) and mechanical AVR (HR: 0.45; 95% CI: 0.26-0.79; P = 0.006). At 15 years, the Ross procedure was associated with a lower cumulative risk of reintervention (P = 0.008) and endocarditis (P = 0.01) than biological AVR. In contrast, at 15 years, the Ross procedure was associated with a higher cumulative incidence of reoperation (P < 0.001) but lower risks of stroke (P = 0.03) and major bleeding (P = 0.016) than mechanical AVR. Thirty-day mortality after valve-related complications was lowest after a reintervention. CONCLUSIONS In young adults, the Ross procedure is associated with better long-term survival and freedom from valve-related complications compared with prosthetic AVR. This confirms the notion that a living valve substitute in the aortic position translates into improved clinically relevant outcomes.

Abstract
OBJECTIVES The choice of optimal surgical treatment for young and middle-aged adults with aortic valve disease remains a challenge. Mechanical aortic valve replacement (mAVR) is generally preferred despite promising recent outcomes of the Ross procedure. Our goal was to compare the strategies at a nationwide level. METHODS This study was a retrospective analysis of prospectively recorded data from the National Registry of Cardiac Surgery of the Czech Republic. Using propensity score matching, we compared the outcomes of patients undergoing the Ross procedure in 2 dedicated centres with all mAVRs performed in country between 2009 and 2020. RESULTS Throughout the study period, 296 adults underwent the Ross procedure and 5120 had an mAVR. We found and compared 291 matched pairs. There were no in-hospital deaths, and the risk of perioperative complications was similar in both groups. Over the average follow-up period of 4.1 vs 6.1 years, the Ross group had a lower all-cause mortality (0.7 vs 6.5%; P = 0.015). This result remained significant even when accounting for cardiac- and valve-related deaths only (P = 0.048). Unlike the Ross group, the mAVR group had a significantly lower relative survival compared with the age- and sex-matched general population. There was no difference in the risk of reoperation (4.5 vs 5.5%; P = 0.66). CONCLUSIONS The Ross procedure offers a significant midterm survival benefit over mAVR. The procedures have a comparable risk of perioperative complications. Patients after mAVR have reduced survival. Thus, the Ross procedure should be the preferred treatment option for young and middle-aged adults with aortic valve disease in dedicated centres.

Abstract
OBJECTIVE The ideal valve substitute for surgical intervention of congenital aortic valve disease in children remains unclear. Data on outcomes beyond 10-15 years after valve replacement are limited but important for evaluating substitute longevity. We aimed to describe up to 25-year death/cardiac transplant by type of valve substitute and assess the potential impact of treatment centre. Our hypothesis was that patients with pulmonic valve autograft would have better survival than mechanical prosthetic. METHODS This is a retrospective cohort study from the Pediatric Cardiac Care Consortium, a multi-institutional US-based registry of paediatric cardiac interventions, linked with the National Death Index and United Network for Organ Sharing through 2019. Children (0-20 years old) receiving aortic valve replacement (AVR) from 1982 to 2003 were identified. Kaplan-Meier transplant-free survival was calculated, and Cox proportional hazard models estimated hazard ratios for mechanical AVR (M-AVR) versus pulmonic valve autograft. RESULTS Among 911 children, the median age at AVR was 13.4 years (IQR=8.4-16.5) and 73% were male. There were 10 cardiac transplants and 153 deaths, 5 after transplant. The 25-year transplant-free survival post AVR was 87.1% for autograft vs 76.2% for M-AVR and 72.0% for tissue (bioprosthetic or homograft). After adjustment, M-AVR remained related to increased mortality/transplant versus autograft (HR=1.9, 95% CI=1.1 to 3.4). Surprisingly, survival for patients with M-AVR, but not autograft, was lower for those treated in centres with higher in-hospital mortality. CONCLUSION Pulmonic valve autograft provides the best long-term outcomes for children with aortic valve disease, but AVR results may depend on a centre's experience or patient selection.

Abstract
Background Even after decades of intensive research, an ideal heart valve prosthesis remains elusive. Shortcomings of conventional devices include reduced durability of bioprostheses and the thrombogenicity of mechanical substitutes, necessitating anticoagulation and resulting in imperfect hemodynamics. Here we present in vivo results of a novel mechanical heart valve prosthesis aiming for freedom from anticoagulation. Methods Four female sheep had their aortic valves replaced using the novel mechanical heart valve (size 21 mm), with no postoperative anticoagulation treatment. This trileaflet heart valve was designed with the pivots in the systolic central flow. Hemodynamics, biochemistry, hematology, and macroscopy and microscopy were studied at 90 days in 2 sheep and at 1 year in the other 2 sheep. Results Mean (<6 mm Hg) and peak (<10 mm Hg) aortic transvalvular gradients remained low during the study period. Aortic regurgitation was trivial, and central traces were only rarely observed. The rate of thrombotic events was very low, with none macroscopically and microscopically visible thrombotic material on the device. Biochemistry and hemotology were unchanged without hemolysis. In 3 sheep, the fibrous pannus and mitral leaflet were partially folded over the edge of the annular body. Apart from organic/inorganic deposits on the leaflets after 1 year, the ultrastructurally evaluated leaflets were similar to those of nonimplanted controls. Conclusions The preliminary in vivo results of this novel anticoagulation-free aortic mechanical heart valve are promising with excellent hemodynamics and a very low risk of thrombotic events.

Abstract
While aortic valve repair remains the ideal intervention to restore normal valvular function, the optimal aortic valve substitute for patients with a non-repairable aortic valve remains an ongoing subject for debate. In particular, younger patients with a non-repairable valve represent a unique challenge because of their active lifestyle and long life expectancy, which carries a higher cumulative risk of prosthesis-related complications. The Ross procedure, unlike prosthetic or homograft aortic valve replacement (AVR), provides an expected survival equivalent to that of the age and gender-matched general population. Contemporary data has shown that the Ross procedure can be performed safely in centers with expertise, and is associated with improved valvular durability, hemodynamics and quality of life.

Abstract
Prosthetic aortic valve replacements have long been the mainstay of valvular surgery due to their favorable outcomes and low operative complexity. Yet, mechanical valves require lifelong anticoagulation, whereas bioprosthetic valves increase the risk for earlier and more frequent reoperation. Alternative reconstructive techniques have been proposed to address these challenges. These include valve-sparing root replacement procedures if the native aortic valve can be salvaged, and the Ross procedure, which nearly eliminates prosthetic valve-related thromboembolism, anticoagulation-related hemorrhage and endocarditis. Both procedures are technically more complex and thus subject to surgeons' volume and expertise compared to conventional aortic valve replacements. However, they are associated with more favorable outcomes compared to aortic valve replacements if performed by experienced surgeons, especially in younger patients. Nevertheless, despite the growing high-quality literature supporting both procedures, existing multi-society guidelines fail to acknowledge the strength of evidence in support of valve-sparing root replacement procedures and the Ross procedure. In this review, we summarize the existing long-term evidence for the use of each procedure, describe the current guidelines for the treatment of aortic valve pathology, and propose the reevaluation of guidelines based on the available clinical evidence.

Abstract
Background Potential for difficult reoperations has been a concern for patients undergoing a Ross procedure. Data regarding the outcomes of such reoperations is extremely limited. We examined our experience to define the current scope and risk of these operations. Methods Between 1996 and 2020, 83 patients who had a previous Ross procedure underwent 89 reoperative surgeries. There were 72 males and average age was 48 with a range of 18-76. Twenty-four patients had more than one prior reoperation, with five patients having more than one reoperation post Ross. Patients were stratified by primary reason for reoperation including autograft dysfunction, homograft dysfunction, or other cardiac surgical problems. Demographic, operative, and outcomes data were collected from clinical records and placed in a secure data base for analysis. Results A total of 176 procedures were done in the 89 operations. Autograft dysfunction affected 68 patients. Homograft dysfunction affected 27 patients. Both of these were seen in 17 patients. Other cardiac problems required 79 other procedures. There were two (2.2%) operative deaths, with perioperative morbidity affecting six patients (6.7%). Survival following reoperation after Ross was 82.3% and 77.5% (±2), at ten and fifteen years respectively. Conclusions Reoperations after a Ross procedure can be challenging but can be done with a high degree of safety and long-term benefit in experienced hands.

Abstract
The surgical options for significant aortic valve disease include either Ross procedure (RP) or aortic valve replacement (AVR). The exercise stress test is routinely performed in these patients to assess the objective functional capacity. This retrospective study was conducted to evaluate the differences and the longitudinal changes of exercise capacity in patients following the RP and AVR for aortic valve disease. This is an IRB approved retrospective study and included patients who had either RP or AVR performed for aortic valve disease and had at least one exercise stress test performed after the surgical procedure. Patients with other congenital heart disease, pacemaker or defibrillators, and those with inadequate data were excluded. Demographic data including age at surgery, type of surgery and type of aortic valve was collected. Data regarding treadmill cardiopulmonary exercise test (CPET) was also collected. A total of 47 patients met inclusion criteria and were equally represented in each group, i.e. RP [n = 23, 73.9% male, age at surgery 11.2 (4.5-15.9) years] vs. AVR [n = 24, 88% mechanical AVR, 60.9% male, age at surgery 15.1 (12.8-19.4) years]. There was a significant decline in predicted oxygen consumption (%VO2) at time of first post-operative CPET in patients after AVR compared to RP (79 vs. 88%, p = 0.048) over a similar accrued median interval follow-up (4.6 vs. 6.2 years, p = 0.2). The longitudinal follow-up analysis of following AVR (n = 11, 54.5% male, median inter-test duration of 5 years) showed significant decline in peak exercise capacity or VO2 (34.2 vs. 26.2 vs., p = 0.006). In contrast, after RP (n = 12 patients [58.3% male, median inter-test duration 7.1 of years], exercise capacity and other key parameters remained preserved. In this small sentinel study, we report a better initial exercise capacity among patients after RP compared to AVR over an intermediate follow-up. During longitudinal follow-up in a subset of patients, exercise capacity remained preserved amongst the RP group while it further declined in the AVR group.

Abstract
Abstract
Aims
The Valve Academic Research Consortium (VARC), founded in 2010, was intended to (i) identify appropriate clinical endpoints and (ii) standardize definitions of these endpoints for transcatheter and surgical aortic valve clinical trials. Rapid evolution of the field, including the emergence of new complications, expanding clinical indications, and novel therapy strategies have mandated further refinement and expansion of these definitions to ensure clinical relevance. This document provides an update of the most appropriate clinical endpoint definitions to be used in the conduct of transcatheter and surgical aortic valve clinical research.
Methods and results
Several years after the publication of the VARC-2 manuscript, an in-person meeting was held involving over 50 independent clinical experts representing several professional societies, academic research organizations, the US Food and Drug Administration (FDA), and industry representatives to (i) evaluate utilization of VARC endpoint definitions in clinical research, (ii) discuss the scope of this focused update, and (iii) review and revise specific clinical endpoint definitions. A writing committee of independent experts was convened and subsequently met to further address outstanding issues. There were ongoing discussions with FDA and many experts to develop a new classification schema for bioprosthetic valve dysfunction and failure. Overall, this multi-disciplinary process has resulted in important recommendations for data reporting, clinical research methods, and updated endpoint definitions. New definitions or modifications of existing definitions are being proposed for repeat hospitalizations, access site-related complications, bleeding events, conduction disturbances, cardiac structural complications, and bioprosthetic valve dysfunction and failure (including valve leaflet thickening and thrombosis). A more granular 5-class grading scheme for paravalvular regurgitation (PVR) is being proposed to help refine the assessment of PVR. Finally, more specific recommendations on quality-of-life assessments have been included, which have been targeted to specific clinical study designs.
Conclusions
Acknowledging the dynamic and evolving nature of less-invasive aortic valve therapies, further refinements of clinical research processes are required. The adoption of these updated and newly proposed VARC-3 endpoints and definitions will ensure homogenous event reporting, accurate adjudication, and appropriate comparisons of clinical research studies involving devices and new therapeutic strategies.

Abstract
Unicuspid aortic valve disease (UAVD) is a frequent and long-lasting challenge for adult congenital heart disease centers. UAVD patients become usually symptomatic in their twenties or thirties and require a surgical treatment plan which should respect their complete lifespan combined with an adequate quality of life. Unfortunately, all current surgical strategies of congenital aortic valve disease bear some important limitations: (I) Aortic valve replacement using bioprosthetic valves is associated with early structural degeneration and leads frequently to re-operations. (II) Mechanical valves are commonly associated with lifelong risk of severe bleeding due to oral anticoagulation. (III) Using a pulmonary autograft (i.e., Ross procedure) for aortic valve replacement is associated with excellent long-term results in non-elderly patients. However, failure of pulmonary autograft or pulmonary homograft may require re-operations. (IV) Aortic valve repair or Ozaki procedure is only performed in a few heart centers worldwide and is associated with a limited reproducibility and early patch degeneration, suture dehiscence or increased risk of endocarditis. In contrast to degenerative tricuspid aortic valve disease, UAVD remains relatively understudied and reports on UAVD treatment are rare and usually limited to retrospective single-center observations. For this review, we searched PubMed for papers in the English language by using the search words unicuspid aortic valve, congenital aortic valve, Ross procedure, Ozaki procedure, aortic valve repair, mechanical/bioprosthetic aortic replacement, homograft. We read the abstracts of relevant titles to confirm their relevance, and the full papers were then extracted. References from extracted papers were checked for additional relevant reports. This review summarizes current surgical treatment strategies for UAVD including aortic valve replacement using bioprosthetic or mechanical valves, homografts, pulmonary autografts (i.e., Ross procedure) and aortic valve repair techniques for UAV. Furthermore, Ozaki procedure will be discussed.

J Thorac Cardiovasc Surg 2021; 163:1180-1191.e6. [PMID: 33820635 DOI: 10.1016/j.jtcvs.2021.02.093] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 02/23/2021] [Accepted: 02/26/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE Difficult to repair aortic valve lesions, requiring the use of a valve substitute, remain controversial in the face of the Ross procedure, despite undeniable technical advances. This study was undertaken to compare midterm outcomes of children treated using the Ross procedure or aortic valvuloplasty for complex aortic valve lesions. METHODS Between January 2006 and December 2017, 126 patients aged younger than 18 years were treated for complex aortic stenosis and/or aortic insufficiency and were included in this retrospective study. Only aortic valve lesions requiring repair with an autologous or heterologous pericardial patch were considered complex lesions. Propensity score framework analyses were used to compare outcomes of the Ross and aortic valvuloplasty groups while controlling for confounders. RESULTS Among the 126 patients with complex aortic valve lesions, propensity score matching selected 34 unique pairs of patients with similar characteristics. Survival (aortic valvuloplasty, 94.1%; Ross, 91%; P = .89), freedom from overall reintervention (aortic valvuloplasty, 50.1%; Ross, 69%; P = .32), and freedom from infective endocarditis at 8 years (aortic valvuloplasty, 100%; Ross, 85.9%; P = .21) were similar. However, freedom from reintervention in the left ventricular outflow tract at 8 years was lower after aortic valvuloplasty than after the Ross procedure (50.1% vs 100%, respectively; P = .001). CONCLUSIONS Aortic valvuloplasty and the Ross procedure yielded similar 8-year outcomes regarding death, reoperation, and infective endocarditis although aortic valvuloplasty tended to be associated with fewer cases of infective endocarditis. Aortic valvuloplasty using a pericardial patch can be chosen as a first-line strategy for treating complex aortic valve lesions and might offer the possibility of a later Ross procedure.

Abstract
The authors present a case report about the elective replacement of a mechanical Bentall with a bioprosthetic valve. The authors describe a technique whereby the mechanical valve is "broken" off its mechanism and the new valve is sutured in the old cuff.
