Abstract
![]()
Consensus regarding optimal cerebral protection strategy in aortic arch surgery is lacking. We therefore performed a systematic review and meta-analysis to assess outcome differences between unilateral antegrade cerebral perfusion (ACP), bilateral ACP, retrograde cerebral perfusion (RCP) and deep hypothermic circulatory arrest (DHCA). A systematic literature search was performed in Embase, Medline, Web of Science, Cochrane and Google Scholar for all papers published till February 2021 reporting on early clinical outcome after aortic arch surgery utilizing either unilateral, bilateral ACP, RCP or DHCA. The primary outcome was operative mortality. Other key secondary endpoints were occurrence of postoperative disabling stroke, paraplegia, renal and respiratory failure. Pooled outcome risks were estimated using random-effects models. A total of 222 studies were included with a total of 43 720 patients. Pooled postoperative mortality in unilateral ACP group was 6.6% [95% confidence interval (CI) 5.3–8.1%], 9.1% (95% CI 7.9–10.4%), 7.8% (95% CI 5.6–10.7%), 9.2% (95% CI 6.7–12.7%) in bilateral ACP, RCP and DHCA groups, respectively. The incidence of postoperative disabling stroke was 4.8% (95% CI 3.8–6.1%) in the unilateral ACP group, 7.3% (95% CI 6.2–8.5%) in bilateral ACP, 6.4% (95% CI 4.4–9.1%) in RCP and 6.3% (95% CI 4.4–9.1%) in DHCA subgroups. The present meta-analysis summarizes the clinical outcomes of different cerebral protection techniques that have been used in clinical practice over the last decades. These outcomes may be used in advanced microsimulation model. These findings need to be placed in the context of the underlying aortic disease, the extent of the aortic disease and other comorbidities.

Abstract
BACKGROUND AND OBJECTIVES In personalised external aortic root support (PEARS), a custom-made, macroporous mesh is used to stabilise a dilated aortic root and prevent dissection, primarily in patients with genetically driven aortopathies. Data are needed on the safety and postoperative incidence of aortic events. METHODS We present a multicentre cohort study evaluating the first 200 consecutive patients (median age 33 years) undergoing surgery with an intention to perform PEARS for aortic root dilatation in 23 centres between 2004 and 2019. Perioperative outcomes were collected prospectively while clinical follow-up was retrieved retrospectively. Median follow-up was 21.2 months. RESULTS The main indication was Marfan syndrome (73.5%) and the most frequent concomitant procedure was mitral valve repair (10%). An intervention for myocardial ischaemia or coronary injury was needed in 11 patients, 1 case resulting in perioperative death. No ascending aortic dissections were observed in 596 documented postoperative patient years. Late reoperation was performed in 3 patients for operator failure to achieve complete mesh coverage. Among patients with at least mild aortic regurgitation (AR) preoperatively, 68% had no or trivial AR at follow-up. CONCLUSIONS This study represents the clinical history of the first 200 patients to undergo PEARS. To date, aortic dissection has not been observed in the restrained part of the aorta, yet long-term follow-up is needed to confirm the potential of PEARS to prevent dissection. While operative mortality is low, the reported coronary complications reflect the learning curve of aortic root surgery in patients with connective tissue disease. PEARS may stabilise or reduce aortic regurgitation.

Abstract
OBJECTIVES Timing of pulmonary valve replacement (PVR) remains one of the most heavily debated topics in congenital cardiac surgery. We aimed to analyse the temporal evolution of QRS duration before and after PVR. METHODS We included 158 consecutive patients who underwent PVR after previous correction with transannular patch. All 3549 available serial standard 12-lead surface QRS measurements of 158 (100%) patients were analysed with linear mixed-effect modelling. RESULTS PVR was performed at a mean age of 28.0 ± 10.7 years, 23.4 ± 8.4 years after correction. Hospital survival was 98.1%. A longer time interval between ToF correction and PVR (P < 0.001), and an older age at correction (P = 0.015) were predictive of progressive QRS prolongation after PVR. Women on average had a shorter QRS duration (P = 0.005) after PVR. The model predicted that in patients corrected early (model age 0.5 years), PVR within 17 years after correction leads to narrowing or stabilization of QRS width. PVR beyond 17 years was associated with prolongation of QRS duration. In a patient corrected late (model age 5 years), PVR has to be performed within 15 years after correction to prevent prolongation. Finally, a longer time period between correction and PVR was associated with an increased hazard of cardiac death (hazard ratio 1.097, 95% confidence interval 1.002–1.200). CONCLUSIONS Prolongation of QRS duration after PVR was associated with a longer time between correction and PVR, older age at correction and male sex. Prevention of progressive QRS prolongation by earlier PVR can potentially reduce the hazard of adverse events after PVR.

Abstract
OBJECTIVES ![]()
Data on the impact and course of uncorrected tricuspid regurgitation (TR) during left ventricular assist device (LVAD) implantation are scarce and inconsistent. This study explores the clinical impact and natural course of uncorrected TR in patients after LVAD implantation.
METHODS The European Registry for Patients with Mechanical Circulatory Support was used to identify adult patients with LVAD implants without concomitant tricuspid valve surgery. A mediation model was developed to assess the association of TR with 30-day mortality via other risk factors. Generalized mixed models were used to model the course of post-LVAD TR. Joint models were used to perform sensitivity analyses. RESULTS A total of 2496 procedures were included (median age: 56 years; men: 83%). TR was not directly associated with higher 30-day mortality, but mediation analyses suggested an indirect association via preoperative elevated right atrial pressure and creatinine (P = 0.035) and bilirubin (P = 0.027) levels. Post-LVAD TR was also associated with increased late mortality [hazard ratio 1.16 (1.06–1.3); P = 0.001]. On average, uncorrected TR diminished after LVAD implantation. The probability of having moderate-to-severe TR immediately after an implant in patients with none-to-mild TR pre-LVAD was 10%; in patients with moderate-to-severe TR pre-LVAD, it was 35% and continued to decrease in patients with moderate-to-severe TR pre-LVAD, regardless of pre-LVAD right ventricular failure or pulmonary hypertension. CONCLUSIONS Uncorrected TR pre-LVAD and post-LVAD is associated with increased early and late mortality. Nevertheless, on average, TR diminishes progressively without intervention after an LVAD implant. Therefore, these data suggest that patient selection for concomitant tricuspid valve surgery should not be based solely on TR grade.

Abstract
Importance There is no ideal valve substitute for young adults requiring aortic valve replacement. Multicenter data supporting use of the Ross procedure with respect to long-term postoperative valve-related mortality and reintervention, as well as function of the autograft and pulmonary homograft, are needed. Objective To determine the long-term clinical and echocardiographic outcomes in young and middle-aged patients undergoing the Ross procedure. Design, Setting, and Participants A retrospective multicenter international cohort study with a median follow-up period of 9.2 years was conducted in 5 experienced centers regularly performing the Ross procedure. Consecutive patients aged 18 to 65 years were included by each center between 1991 and 2018. Main Outcomes and Measures Survival and autograft-related and homograft-related reintervention. Serial echocardiographic measurements of valve function were analyzed using mixed-effects modeling. Results During the study period, 1431 patients (74.3% men; n = 1063) were operated on at a median age of 48.5 years (mean [SD], 47.7 [9.5]; range, 18.1-65; interquartile range, 42.7-54.0). Implantation techniques were root inclusion in 355 (24.9%), root replacement in 485 (34.0%), and subcoronary implantation in 587 (41.1%). Right ventricular outflow tract reconstruction was performed with homografts in 98.6% (n = 1189) and bioprostheses in 1.4% (n = 17). Ten patients (0.7%) died before discharge. Median follow-up was 9.2 years (13 015 total patient-years). Survival after 10 and 15 years was 95.1% (95% CI, 93.8%-96.5%) and 88.5% (95% CI, 85.9%-91.1%), respectively. Freedom from autograft and homograft reintervention after 15 years was 92.0% and 97.2%, respectively. Late events were autograft endocarditis in 14 patients (0.11% per patient-year), homograft endocarditis in 11 patients (0.08% per patient-year), and stroke in 37 patients (0.3% per patient-year). Conclusions and Relevance Given its excellent short-term and long-term outcome in young and middle-aged adults in this study, the Ross procedure should be considered in young and middle-aged adults who require aortic valve replacement. Patients should be referred to an experienced center with a program dedicated to the Ross procedure.

Abstract
BACKGROUND In response to an increased need for patient information in congenital heart disease, we previously developed an online, evidence-based information portal for patients with congenital aortic and pulmonary valve disease. To assess its effectiveness, a stepped-wedge cluster randomised trial was conducted. METHODS Adult patients and caregivers of paediatric patients with congenital aortic and/or pulmonary valve disease and/or tetralogy of Fallot who visited the outpatient clinic at any of the four participating centres in the Netherlands between 1 March 2016-1 July 2017 were prospectively included. The intervention (information portal) was introduced in the outpatient clinic according to a stepped-wedge randomised design. One month after outpatient clinic visit, each participant completed a questionnaire on disease-specific knowledge, anxiety, depression, mental quality of life, involvement and opinion/attitude concerning patient information and involvement. RESULTS 343 participants were included (221 control, 122 intervention). Cardiac diagnosis (p=0.873), educational level (p=0.153) and sex (p=0.603) were comparable between the two groups. All outcomes were comparable between groups in the intention-to-treat analyses. However, only 51.6% of subjects in the intervention group (n=63) reported actually visiting the portal. Among these subjects (as-treated), disease-specific knowledge (p=0.041) and mental health (p=0.039) were significantly better than in control subjects, while other baseline and outcome variables were comparable. CONCLUSION Even after being invited by their cardiologists, only half of the participants actually visited the information portal. Only in those participants that actually visited the portal, knowledge of disease and mental health were significantly better. This underlines the importance of effective implementation of online evidence-based patient information portals in clinical practice.

Abstract
Objectives Previous studies have reported beneficial effects of perioperative music on patients’ anxiety and pain. We performed a systematic review and meta-analysis of randomised controlled trials investigating music interventions in cardiac surgery. Methods Five electronic databases were systematically searched. Primary outcomes were patients’ postoperative anxiety and pain. Secondary outcomes were hospital length of stay, opioid use, vital parameters and time on mechanical ventilation. PRISMA guidelines were followed and PROSPERO database registration was completed (CRD42020149733). A meta-analysis was performed using random effects models and pooled standardised mean differences (SMD) with 95% confidence intervals were calculated. Results Twenty studies were included for qualitative analysis (1169 patients) and 16 (987 patients) for meta-analysis. The first postoperative music session was associated with significantly reduced postoperative anxiety (SMD = –0.50 (95% CI –0.67 to –0.32), p<0.01) and pain (SMD = –0.51 (95% CI –0.84 to –0.19), p<0.01). This is equal to a reduction of 4.00 points (95% CI 2.56 to 5.36) and 1.05 points (95% CI 0.67 to 1.41) on the State-Trait Anxiety Inventory and Visual Analogue Scale (VAS)/Numeric Rating Scale (NRS), respectively, for anxiety, and 1.26 points (95% CI 0.47 to 2.07) on the VAS/NRS for pain. Multiple days of music intervention reduced anxiety until 8 days postoperatively (SMD = –0.39 (95% CI –0.64 to –0.15), p<0.01). Conclusions Offering recorded music is associated with a significant reduction in postoperative anxiety and pain in cardiac surgery. Unlike pharmacological interventions, music is without side effects so is promising in this population.

Long-term survival after xenograft versus homograft aortic root replacement: Results from a prospective randomized trial. J Thorac Cardiovasc Surg 2021; 161:57-65. [PMID: 31735388 DOI: 10.1016/j.jtcvs.2019.09.119] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Revised: 09/01/2019] [Accepted: 09/04/2019] [Indexed: 01/07/2023]
Abstract
OBJECTIVE The study objective was to investigate the long-term survival of patients undergoing xenograft versus homograft full root aortic valve replacement. METHODS A total of 166 patients requiring aortic valve surgery were randomized to undergo the Freestyle (Medtronic Inc, Minneapolis, Minn) bioprosthesis (N = 90) or a homograft (N = 76) full root aortic valve replacement between 1997 and 2005 in a single institution. Six patients randomly assigned to the homograft crossed over to the Freestyle bioprosthesis because of the unavailability of suitably sized homografts. All surgeons were required to adhere to the standard surgical technique for homograft root implantation previously described. Follow-up was 98.5% complete. RESULTS The mean age of the study population was 65 ± 8 years. Coronary artery bypass grafting was associated with root aortic valve replacement in 76 of 166 patients (46%, P = not significant between groups), and overall hospital mortality was 4.8% (8/166, P = not significant between groups). Median follow-up was 13.8 years (range, 0-21.8 years; 2033 patient-years). The Kaplan-Meier survival analysis showed that there was no significant difference in overall survival between the 2 arms at 5, 10, and 15 years. Twenty-year survival was 28.3% ± 5% for the Freestyle group versus 25.1% ± 5.7% for the homograft group (P = .90), which was comparable to the age- and sex-matched UK general population. The freedom from aortic valve reoperation at 20 years was comparable for the Freestyle group versus the homograft group (67.9% ± 8.8% vs 67.2% ± 10.3%, respectively; P = .74). CONCLUSIONS This is the first study to investigate the long-term survival of xenograft versus homograft full root aortic valve replacement from a prospective randomized trial. The observed 20-year overall survival and freedom from aortic valve reoperation serve as a benchmark for future studies on interventions for aortic valve disease in the elderly.

Abstract
Objective Thoracic aortic disease (TAD) may have substantial impact on health-related quality of life (HRQOL). We described HRQOL in patients with TAD, cardiovascular screening participants and their partners; identified factors associated with HRQOL; and explored lived experiences and feelings of anxiety or depression using a mixed methods design. Methods For this cross-sectional study, all consecutive patients visiting the TAD outpatient clinic (2017–2019) at our centre were asked to complete three questionnaires: the Short Form 36 (SF-36), the Hospital Anxiety and Depression Scale (HADS) and the Rotterdam Disease Specific Questionnaire (RDSQ). A subsample was invited for in-depth interviews. Results In total, 261 participants were included: 147 patients with TAD (thoracic aortic diameter ≥40 mm; 54 females, 36.7%), 114 screening participants (cardiovascular family screening; 71 females, 62.3%) and 66 partners. Compared with the general population, patients with TAD showed markedly lower HRQOL, whereas screening participants’ HRQOL was less impaired. Female and younger participants scored significantly lower on the SF-36 and HADS compared with male and older participants. Smaller aortic diameter was associated with better RDSQ score, and previous aortic surgery was associated with higher HADS depression scores. Furthermore, partners scored significantly lower on 2/8 SF-36 subdomains when compared with the general population. From 11 interviewees, determinants of psychological distress included coping strategies, impact on social and professional life, disease-related knowledge, state of aortic diameters and physical symptoms. Conclusions Healthcare professionals must be aware of HRQOL impairments in patients with TAD, particularly in younger females. Moreover, attention for partners is needed. Coping strategies and communication within the family were found to be important factors influencing psychological distress, and might be valuable leads for counselling and HRQOL improvement in this population.

Abstract
OBJECTIVES This study aims to explore male-female differences in baseline and procedural characteristics, and outcomes of patients undergoing isolated or concomitant tricuspid valve (TV) surgery. METHODS All TV procedures registered between 2007 and 2016 in the database of the Netherlands Association for Cardio-Thoracic Surgery were analysed. Logistic regression analyses with interaction terms were used to determine whether sex was associated with hospital mortality. RESULTS Five thousand five hundred and eighty-two patients underwent TV surgery [isolated: N = 685 (49% male), TVrepair: N = 5286 (50% male) and TVreplacement: N = 250 (46% male)]. In the TVrepair group, females were significantly older, had less prior percutaneous/surgical coronary interventions, less extracardiac arteriopathies, a lower prevalence of renal impairment, less endocarditis, a lower prevalence of preoperative critical condition, less recent myocardial infarction, less concomitant coronary artery bypass grafting (CABG) and, in case of concomitant mitral valve surgery, less concomitant mitral valve repair compared to males. In the TVreplacement group, females more often had a history of prior valve surgery and less prior CABG. Hospital mortality for males and females was 7.0% (N = 183) and 6.1% (N = 163), P = 0.241 in the TVrepair group and 2.6% (N = 3) and 8.8% (N = 12), P = 0.074 in the TVreplacement group. Sex was not associated with hospital mortality (odds ratio (OR) 1.14, 95% confidence interval (CI) 0.88-1.48; P = 0.322). Sex demonstrated a significant interaction with the parameter 'critical preoperative condition' (OR 0.44, 95% CI 0.22-0.90; P = 0.026). CONCLUSIONS Substantial differences in patient and procedural characteristics existed between male and female patients undergoing TV surgery, although sex was not a derterminant for hospital mortality. Nevertheless, sex interacted with a critical preoperative condition, indicating the usefulness of separate risk factor models for males and females requiring TV surgery.

Long-term clinical outcome and echocardiographic function of homografts in the right ventricular outflow tract†. Eur J Cardiothorac Surg 2020; 55:518-526. [PMID: 30084965 DOI: 10.1093/ejcts/ezy265] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 06/25/2018] [Accepted: 06/25/2018] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES Although homografts are often the preferred valve conduits for right ventricular outflow tract (RVOT) reconstruction, data on long-term homograft-related outcomes, durability and impact on quality of life (QoL) are scarce. The aim of this study was therefore to describe the long-term homograft function, clinical outcomes and QoL after RVOT reconstruction. METHODS We performed a single-centre retrospective analysis of all consecutive patients who underwent RVOT reconstruction with a homograft. Multiple subsequent allografts in the same patients were regarded as separate subjects. Valve-related events were analysed by Kaplan-Meier and Life Table methods. Serial echocardiographic measurements were analysed with mixed effects models. In addition, QoL was repeatedly assessed and compared with a matched general population. RESULTS In total, 701 consecutive homografts were implanted in 604 patients [59.6% males, mean age at operation 19.5 ± 15.2 (standard deviation)]. Hospital mortality was 3.3%. After 25 years follow-up, survival and freedom from valve replacement were 84 ± 4% and 56 ± 6%, respectively. Freedom from valve replacement after 15 years for patients under 1 year of age was 28 ± 14% years, for those between 1 and 18 years, 59 ± 8%, and for those older than 18 years, 82 ± 5%. The peak gradient increased predominantly in the first postoperative decade in infants and paediatric patients from 19 to 54 mmHg. In adults, the average gradient increased from 9 to 31 mmHg after 14 years. Compared to a gender- and age-matched Dutch population, patients reported lower vitality and general health but less bodily pain. Patients, in whom QoL was repeatedly assessed, reported lower scores on physical functioning and vitality after a 5-year follow-up period. However, we found no differences in any of the subscales in patients who underwent valve replacement during the 5-year interval. CONCLUSIONS Homografts are a durable valve alternative for RVOT reconstruction; in particular, adults show extensive freedom from valve replacement and report QoL comparable with healthy subjects. An online interactive application form created by our institution can be used to assess patient outcome after RVOT reconstruction with a homograft for different patient profiles.

Abstract
Patients with congenitally determined aortic root aneurysms are at risk of aortic valve regurgitation, aortic dissection, rupture and death. Personalised external aortic root support (PEARS) may provide an alternative to aortic root replacement. This was a multi-centre, prospective cohort of all consecutive patients who received ExoVasc mesh implants for a dilated aortic root between 2004 and 2017. Baseline and peri-operative characteristics, as well as early postoperative outcomes are described, and time-related survival and re-operation free survival are estimated using the Kaplan-Meier method. From 2004 through 2017, 117 consecutive patients have received ExoVasc mesh implants for aortic root aneurysm. The inclusion criteria were an aortic root/sinus of Valsalva and ascending aorta with asymptomatic dilatation of between 40 and 50 mm in diameter in patients aged 16 years or more. Patients with more than mild aortic regurgitation were excluded. There was one early death. The length of stay was within seven days in 75% of patients. In conclusion, the operation achieves the objectives of valve-sparing root replacement. PEARS may be seen as a low-risk conservative operation, which can be applied earlier on in the disease process, and which is complementary to more invasive procedures, such as valve-sparing root replacement or total root replacement.

Abstract
PURPOSE With the increasing interest in treatment decision-making based on risk prediction models, it is essential for clinicians to understand the steps in developing and interpreting such models. METHODS A retrospective registry of 20 Dutch hospitals with data on patients treated for castration-resistant prostate cancer was used to guide clinicians through the steps of developing a prediction model. The model of choice was the Cox proportional hazard model. RESULTS Using the exemplary dataset several essential steps in prediction modelling are discussed including: coding of predictors, missing values, interaction, model specification and performance. An advanced method for appropriate selection of main effects, e.g. Least Absolute Shrinkage and Selection Operator (LASSO) regression, is described. Furthermore, the assumptions of Cox proportional hazard model are discussed, and how to handle violations of the proportional hazard assumption using time-varying coefficients. CONCLUSION This study provides a comprehensive detailed guide to bridge the gap between the statistician and clinician, based on a large dataset of real-world patients treated for castration-resistant prostate cancer.

Male-female differences in quality of life and coping style in patients with Marfan syndrome and hereditary thoracic aortic diseases. J Genet Couns 2020; 29:1259-1269. [PMID: 32519797 PMCID: PMC7754440 DOI: 10.1002/jgc4.1288] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Revised: 04/09/2020] [Accepted: 04/20/2020] [Indexed: 12/12/2022]
Abstract
Hereditary thoracic aortic diseases (HTAD) such as Marfan syndrome (MFS) affect multiple organ systems and provide a risk of acute aortic dissection, which causes lifelong uncertainties. Although health‐related quality of life (HRQOL) was found to be reduced in HTAD patients, no studies have evaluated male–female‐specific aspects of HRQOL and coping in this population. This study aims to evaluate HRQOL in HTAD patients compared to the general population; assess male–female differences in HRQOL and factors associated with HRQOL; evaluate coping styles in male and female HTAD patients and identify factors associated with acceptance. All consecutive adult patients who visited the specialized HTAD outpatient clinic between 2013 and 2018 were asked to complete three HRQOL questionnaires: the Short Form 36 (SF‐36), the Hospital Anxiety and Depression Scale (HADS), and the Nijmegen Clinical Screening Instrument (NCSI). In total, 142 patients were included (mean age 42.1 years, 65 females, 123 MFS). Compared to the general population, HTAD patients scored significantly lower on multiple SF‐36 sub‐domains (males: General Health 54.5 ± 18.8 vs. 71.6 ± 20.6, p < .001; Vitality 58.3 ± 20.4 vs. 71.9 ± 18.3, p < .001; females: Physical Functioning 67.5 ± 23.8 vs. 80.4 ± 24.2, p = .003; Role Physical 58.3 ± 45.1 vs. 73.8 ± 38.5, p = .047; General Health 49.4 ± 24.3 vs. 69.9 ± 20.6, p < .001; Social Functioning 73.5 ± 22.0 vs. 82.0 ± 23.5, p = .027). Females scored significantly lower than males on the SF‐36 physical component score (41.6 [IQR 35.5–53.1] vs. 49.3 [IQR 42.3–54.6], p = .035). Males scored significantly higher on the coping style denial than females (2.75 [IQR 2.00–3.25] vs. 2.25 [IQR 1.75–3.25], p = .018). High scores on acceptance were found in 38 (26.8%) of HTAD patients, and these patients showed significantly better scores on the NCSI, SF‐36, and HADS, except on NCSI Satisfaction Relationships and SF‐36 Physical Functioning and Mental Health. Acceptance was associated with more medication use (beta blocker use, p = .008; angiotensin receptor blocker use, p = .003) and less hypertension (p = .001). In patients with MFS, employment was strongly associated with better scores on the NCSI. In conclusion, HTAD patients showed subnormal HRQOL, especially females. Interestingly, in both males and females factors such as employment, coping style, and disease acceptance seem more important for HRQOL than disease‐related factors. This highlights the importance of genetic counseling and guidance for HTAD patients, and offers valuable leads for HRQOL improvement.

Early cost-utility analysis of tissue-engineered heart valves compared to bioprostheses in the aortic position in elderly patients. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2020; 21:557-572.

Abstract
OBJECTIVES Aortic valve disease is the most frequent indication for heart valve replacement with the highest prevalence in elderly. Tissue-engineered heart valves (TEHV) are foreseen to have important advantages over currently used bioprosthetic heart valve substitutes, most importantly reducing valve degeneration with subsequent reduction of re-intervention. We performed early Health Technology Assessment of hypothetical TEHV in elderly patients (≥ 70 years) requiring surgical (SAVR) or transcatheter aortic valve implantation (TAVI) to assess the potential of TEHV and to inform future development decisions. METHODS Using a patient-level simulation model, the potential cost-effectiveness of TEHV compared with bioprostheses was predicted from a societal perspective. Anticipated, but currently hypothetical improvements in performance of TEHV, divided in durability, thrombogenicity, and infection resistance, were explored in scenario analyses to estimate quality-adjusted life-year (QALY) gain, cost reduction, headroom, and budget impact. RESULTS Durability of TEHV had the highest impact on QALY gain and costs, followed by infection resistance. Improved TEHV performance (- 50% prosthetic valve-related events) resulted in lifetime QALY gains of 0.131 and 0.043, lifetime cost reductions of €639 and €368, translating to headrooms of €3255 and €2498 per hypothetical TEHV compared to SAVR and TAVI, respectively. National savings in the first decade after implementation varied between €2.8 and €11.2 million (SAVR) and €3.2-€12.8 million (TAVI) for TEHV substitution rates of 25-100%. CONCLUSIONS Despite the relatively short life expectancy of elderly patients undergoing SAVR/TAVI, hypothetical TEHV are predicted to be cost-effective compared to bioprostheses, commercially viable and result in national cost savings when biomedical engineers succeed in realising improved durability and/or infection resistance of TEHV.

Abstract
Abstract
OBJECTIVES
This study provides an overview of the change over a 45-year time period in the characteristics and outcome of patients with tricuspid valve disease undergoing surgical tricuspid valve replacement (TVR).
METHODS
The characteristics and outcomes of all consecutive TVRs from November 1972 to November 2017 at Erasmus MC were collected retrospectively. A logistic regression analysis was conducted to identify the significant predictors of 30-day mortality. Multivariable Cox regression analysis was used to identify the potential risk factors of patient outcome and the effect of time on these factors.
RESULTS
Ninety-eight patients with tricuspid valve dysfunction underwent 114 consecutive TVRs at a mean age of 50.1 ± 17.2 years (68.5% female). Aetiology changed over time from predominantly functional regurgitation (42.9% in 1972-1985) to predominantly carcinoid heart disease (47.7% in 2001-2017). Early mortality declined significantly from 35% in 1972–1985 to 6.7% in 2001–2017 (P < 0.001). Over time, the hazard ratio of late mortality decreased for higher New York Heart Association class, lower preoperative haemoglobin, and high central venous pressure and increased for the presence of preoperative leg oedema, higher creatinine and alkaline phosphatase. The late survival was 43.8% ± 5.89% at 10 years and was comparable among eras (P = 0.44). The cumulative incidence of reoperation at 10 years was 14.1% (2.3–26.0) in biological valves and 4.9% (0.1–10.3) in mechanical valves (P = 0.25).
CONCLUSIONS
Patient characteristics, potential risk factors and patient outcome changed considerably over time in patients undergoing TVR. Notably, there was a shift in aetiology, completely altering the patient population and their characteristics.

A randomized, investigator-blinded general population survey. Int J Med Inform 2019; 135:104005.

Abstract
BACKGROUND Risk visualizations are often employed to support risk communication. However, their effectiveness in communication of single absolute risks remains unclear. We investigated the effectiveness of risk visualizations in conveying verbatim knowledge of single absolute risks among the general population. METHODS Randomly sampled members of the general Dutch population completed four basic risk conversions from percentages to natural frequencies and vice versa. By random investigator-blinded allocation, these conversions were supported by either icon arrays, pie charts, bar graphs or no visualization. Verbatim risk knowledge was scored as the number of conversions completed correctly. RESULTS 393 subjects were included. Overall, 60% of respondents answered all four questions correctly. Risk format (percentages vs. natural frequencies, p = 0.677) and risk magnitude (p = 0.532) were not associated with verbatim risk knowledge score. Younger age (p = 0.001) and higher education level (p < 0.001) were independently associated with higher scores. The use of risk visualizations was not associated with higher scores (OR = 1.08; 95% confidence interval: 0.69-1.69; p = 0.745). All three forms of risk visualization were equally ineffective. These findings held when stratifying by risk format, risk magnitude and user preference for a certain form of risk visualization. There were no significant interactions with age or education level. CONCLUSION Risk visualizations did not improve conveyance of verbatim knowledge of single absolute risks, irrespective of age, education level, risk magnitude, risk format and form of risk visualization. Risk visualizations may therefore be less suitable for settings in which detailed conveyance of single absolute risks is the main objective, although their effect on user experience and perception of risk communication and subsequent patient activation and participation remains to be elucidated.

Abstract
BACKGROUND There is very limited published evidence about the influence of pregnancy on allograft durability in right ventricular outflow tract position. We present the first study using mixed and joint modeling. METHODS This retrospective study compared clinical and valve related outcomes of all consecutive female hospital survivors in their fertile life phase (18-50 years) based on pregnancy. Serial echocardiographic measurements of pulmonary gradient and regurgitation were analyzed for their association with valve replacement using joint models for longitudinal and time-to-event data. Occurrence of first pregnancy was included as a time-dependent intermediate event in both the longitudinal and survival analyses of the joint model to assess its impact on the hemodynamic and clinical outcome. RESULTS In total, 196 consecutive women in their fertile life-phase with an allograft were included. Complete information of 176 (90%) allografts in 165 women was available, including 1395 echocardiograms. Of these women, 51 (30.9%) women had 84 completed pregnancies at an average age of 29.1 ± 3.9 (SD) years; 8.1 ± 6.1 years since allograft implantation. Tetralogy of Fallot was the most common diagnosis in both groups. After a mean follow-up of 15.2 years (range 0.1-30), 7 (13.7%) parous women underwent valve replacement versus 20 (17.5%) nulliparous women. During this follow-up, the mean allograft gradient in parous (24.2 mm Hg) and nulliparous (21.0 mm Hg) women was comparable (P = .225). A 1-mm Hg increase in pulmonary gradient increased the instantaneous risk of pulmonary valve replacement (PVR) by a ratio of 1.051 (P < .001), regardless of pregnancy. Similarly, development of moderate or severe regurgitation increased the risk of PVR (P = .038), regardless of pregnancy. Pregnancy was not associated with a change in the allograft gradient (P = .258), regurgitation grade (P = .774), or hazard of PVR (P = .796) during follow-up. CONCLUSIONS Pregnancy is not associated with impaired allograft durability in women with good cardiac health.

Abstract
BACKGROUND Honorary authorship (HA) refers to enlisted authors who did not make sufficient contributions to a paper according to the guidelines, as defined by the International Committee of Medical Journal Editors (ICMJE). This study assessed the proportion of, and factors associated with, HA in cardiothoracic surgical literature in 2017. METHODS Five cardiothoracic surgery journals were selected based on their impact factors in 2017 for evaluation of HA. Articles were included in the analysis if there was more than 1 listed author and if there was an available E-mail address of the corresponding author. All corresponding authors received an invitation to fill out our survey regarding their paper in 2017. RESULTS In total, 1511 authors opened the invitation, resulting in a total of 590 respondents (28.9%); 77.1% of all authors were aware of the ICMJE guidelines and 47.0% were aware of the general issue of HA. A total of 367 (62.7%) authors stated that at least one of the coauthors had performed solely nonauthorship tasks, whereas 148 (25.3%) authors stated that they believed that their article contained at least one honorary author. Having a senior member who was automatically included on all submitted manuscripts and not being aware of the general issue of HA were associated with significantly greater odds of having HA. CONCLUSIONS Our results show that, despite the high awareness of the ICMJE guidelines, there is a large discrepancy in perceived HA and guideline-based HA. The authors plead for a better understanding and implementation of the guidelines in a more transparent authorship system.
