Abnormal Cardiac Magnetic Resonance-Derived Ascending Aortic Area Strain Demonstrates Altered Ventriculo-Vascular Function in Marfan Syndrome.

PURPOSE: There remains a need for improved imaging markers for risk stratification and treatment guidance in Marfan syndrome (MFS). After aortic root replacement (ARR), vascular remodeling and progressive aneurysm formation can occur due to alterations in up- and downstream wall biomechanics and hemodynamics. We aim to compare the ventriculo-vascular properties of patients with MFS with controls, and investigate the correlation between ascending aortic area strain and descending aortic area strain (DAAS) with other clinical variables. PATIENTS AND METHODS: Nineteen patients with MFS (47% males), including 6 with ARR were studied. In 26 studies, aortic area strain was measured using cross-sectional cardiac magnetic resonance images at the ascending and proximal descending aortic levels. Left atrial, left ventricular longitudinal, and left ventricle circumferential strain (left atrial longitudinal strain, left ventricular longitudinal strain, and left ventricular circumferential strain, respectively) were measured using cardiac magnetic resonance-feature tracking. RESULTS: Compared with healthy controls, patients with MFS had significantly impaired left ventricular longitudinal strain and left ventricular circumferential strain (-15.8 ± 4.7 vs -19.7 ± 4.8, P = 0.005, and -17.7 ± 4.0 vs -27.0 ± 4.1, P < 0.001). Left atrial longitudinal strain was comparable between patients with MFS and controls. AAAS was significantly reduced (19.0 [11.9, 23.7] vs 46.1 ± 11.3, P < 0.001), whereas DAAS was not significantly decreased. AAAS and DAAS were negatively correlated with age, whereas no significant associations were identified with left ventricle function indices. No significant differences were observed between the ventriculo-vascular properties of patients with MFS who underwent ARR and those who did not. CONCLUSION: Patients with MFS demonstrated impaired ventricular and vascular function compared with healthy controls. Further investigations are warranted to determine clinical utility of aortic stiffness indices for predicting primary and repeat aortic events.

Renal Sodium Avidity in Heart Failure.

BACKGROUND: Increased renal sodium avidity is a hallmark feature of the heart failure syndrome. SUMMARY: Increased renal sodium avidity refers to the inability of the kidneys to elicit potent natriuresis in response to sodium loading. This eventually causes congestion, which is a major contributor to hospital admissions and mortality in heart failure. KEY MESSAGES: Important novel concepts such as the renal tamponade hypothesis, accelerated nephron loss, and the role of hypochloremia, the sympathetic nervous system, inflammation, the lymphatic system, and interstitial sodium buffers are involved in the pathophysiology of renal sodium avidity. A good understanding of these concepts is crucially important with respect to treatment recommendations regarding dietary sodium restriction, fluid restriction, rapid up titration of guideline-directed medical therapies, combination diuretic therapy, natriuresis guided diuretic therapy, use of hypertonic saline, and ultrafiltration.

Impact of Prosthesis-Patient Mismatch After Surgical Aortic Valve Replacement: Systematic Review and Meta-Analysis of Reconstructed Time-to-Event Data of 122 989 Patients With 592 952 Patient-Years.

BACKGROUND: It remains controversial whether prosthesis-patient mismatch (PPM) impacts long-term outcomes after surgical aortic valve replacement. We aimed to evaluate the association of PPM with mortality, rehospitalizations, and aortic valve reinterventions. METHODS AND RESULTS: We performed a systematic review with meta-analysis of reconstructed time-to-event data of studies published by March 2023 (according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Sixty-five studies met our eligibility criteria and included 122 989 patients (any PPM: 68 332 patients, 55.6%). At 25 years of follow-up, the survival rates were 11.8% and 20.6% in patients with and without any PPM, respectively (hazard ratio [HR], 1.16 [95% CI, 1.13-1.18], P<0.001). At 20 years of follow-up, the survival rates were 19.5%, 12.1%, and 8.8% in patients with no, moderate, and severe PPM, respectively (moderate versus no PPM: HR, 1.09 [95% CI, 1.06-1.11], P<0.001; severe versus no PPM: HR, 1.29 [95% CI, 1.24-1.35], P<0.001). PPM was associated with higher risk of cardiac death, heart failure-related hospitalizations, and aortic valve reinterventions over time (P<0.001). Statistically significant associations between PPM and worse survival were observed regardless of valve type (bioprosthetic versus mechanical valves), contemporary PPM definitions unadjusted and adjusted for body mass index, and PPM quantification method (in vitro, in vivo, Doppler echocardiography). Our meta-regression analysis revealed that populations with more women tend to have higher HRs for all-cause death associated with PPM. CONCLUSIONS: The results of the present study suggest that any degree of PPM is associated with poorer long-term outcomes following surgical aortic valve replacement and provide support for implementation of preventive strategies to avoid PPM after surgical aortic valve replacement.

Occult solitary fibrous tumour of the pleura presenting as recurrent spontaneous pneumothorax.

A woman in her 30s, non-smoker, presented at the emergency department two times because of spontaneous pneumothorax. The first episode was treated with small bore catheter drainage, while during the second episode-occurring only 1 week later-thoracoscopic talcage was attempted. The postoperative course was characterised by slow clinical and radiological resolution, and recurrence 3 days after discharge. Eventually, multiportal video-assisted thoracoscopic exploration identified an interfissural solid mass. Resection and further work-up revealed the diagnosis of 'low-risk' solitary fibrous tumour (SFT) stage pT1N0M0. The interdisciplinary tumour board advised no adjuvant therapy. A CT thorax was scheduled in 1 year for follow-up. The patient was discharged without complications and has had no recurrences of pneumothorax at 6 months of follow-up. This report shows that SFT can easily be missed on initial presentation and should be considered in the differential diagnosis of pneumothorax, especially when frequently recurring.

Effect of haemoadsorption during cardiac surgery for Staphylococcus aureus endocarditis: a REMOVE trial post hoc analysis.

OBJECTIVES: Multi-organ failure is one of the leading causes of mortality after cardiac surgery for infective endocarditis (IE). Although the randomized evidence does not support the use of haemoadsorption during cardiac surgery for IE, observational studies suggest a beneficial effect in selected patient groups. Staphylococcus aureus is the most common pathogen, and its presence is an independent mortality predictor. We aimed to analyse the effect of haemoadsorption in patients with IE caused by S. aureus. METHODS: This is a post hoc analysis of the REMOVE trial that randomized 288 patients with IE who underwent cardiac surgery with haemoadsorption using CytoSorb® or control. The primary outcome was ΔSequential Organ Failure Assessment (SOFA), defined as the difference between the mean total postoperative and baseline SOFA score within 24 h of surgery. RESULTS: Among the total of 282 patients included in the modified intention-to-treat analysis of the REMOVE trial, 73 (25.9%) had S. aureus IE (38 patients in the haemoadsorption group and 35 patients in the control group). The overall ΔSOFA did not differ between the intervention groups in patients with S. aureus IE (mead difference = -0.4, 95% confidence interval -2.3 to 1.4, P = 0.66) and neither did 30-day mortality (hazard ratios = 1.32, 95% confidence interval 0.53-3.28, P = 0.55). No differences were observed with regard to any of the other secondary outcomes. CONCLUSIONS: Based on a post hoc analysis from REMOVE trial, the intraoperative use of haemoadsorption in patients with S. aureus IE was not associated with reduction of postoperative organ dysfunction, 30-day mortality or other major clinical end points.

Innovations in Aortic Valve Replacement: A Comprehensive Overview of the Intuity Rapid Deployment Valve.

Rapid deployment/sutureless (RDS) valves have recently emerged as an innovative surgical solution, providing an alternative to traditional methods of surgical aortic valve replacement (SAVR) by eliminating the need for suture placement and tying. This innovation leads to a reduction in aortic crossclamp and cardiopulmonary bypass times, enhancing the efficiency of the procedure. Among the 2 available RDS valves, the Edwards Intuity valve in particular has been demonstrated to be a particularly promising substitute in the field of SAVR. The Intuity valve distinguishes itself from other RDS and conventional valves by yielding superior outcomes, such as a significant reduction in mortality, increase in the longevity of the valve, and a marked decrease in both mean and peak transvalvular pressure gradients. These benefits collectively contribute to its appeal as a favorable new solution. However, further investigation is needed to conclusively determine the long-term outcomes and safety of RDS valves. Nevertheless, the utilization of the Intuity valve presents an exciting solution to the existing limitations of conventional and minimally invasive SAVR, especially for patients afflicted with severe aortic stenosis.

Noninvasive Advanced Cardiovascular Magnetic Resonance-Derived Fontan Hemodynamics Are Associated With Reduced Kidney Function But Not Albuminuria.

BACKGROUND: Kidney disease is the most important predictor of death in patients with a Fontan circulation, yet its clinical and hemodynamic correlates have not been well established. METHODS AND RESULTS: A total of 53 ambulatory patients with a Fontan circulation (median age, 16.2 years, 52.8% male patients) underwent advanced cardiovascular magnetic resonance assessment, including 4-dimensional flow imaging and computational fluid dynamics. Estimated glomerular filtration rate (eGFR) <90 mL/min per 1.73 m2 was observed in 20.8% and albumin-to-creatinine ratio >3 mg/mmol in 39.6%. The average eGFR decline rate was -1.83 mL/min per 1.73 m2 per year (95% CI, -2.67 to -0.99; P<0.001). Lower eGFR was associated with older age, larger body surface area at examination, longer time since Fontan procedure, and lower systemic ventricular ejection fraction. Higher albumin-to-creatinine ratio was associated with absence of fenestration at the Fontan operation, and older age and lower systemic ventricular ejection fraction at the assessment. Lower cross-sectional area of the Fontan conduit indexed to flow (r=0.32, P=0.038), higher inferior vena cava-conduit velocity mismatch factor (r=-0.35, P=0.022), higher kinetic energy indexed to flow in the total cavopulmonary connection (r=-0.59, P=0.005), and higher total cavopulmonary connection resistance (r=-0.42, P=0.005 at rest; r=-0.43, P=0.004 during exercise) were all associated with lower eGFR but not with albuminuria. CONCLUSIONS: Kidney dysfunction and albuminuria are common among clinically well adolescents and young adults with a Fontan circulation. Advanced cardiovascular magnetic resonance-derived metrics indicative of declining Fontan hemodynamics are associated with eGFR and might serve as targets to improve kidney health. Albuminuria might be driven by other factors that need further investigation.

Respect Versus Resect Approaches for Mitral Valve Repair: A Meta-Analysis of Reconstructed Time-to-Event Data.

Mitral valve repair (MVr) has been associated with superior long-term survival and freedom from valve-related complications compared with mitral valve replacement for primary mitral regurgitation (MR). The 2 main approaches for MVr are chordal replacement ("respect approach") and leaflet resection ("resect approach"). We performed a systematic review and a meta-analysis using 3 search databases to compare the long-term end points between both approaches. The primary end point was long-term survival. The secondary end points were long-term MR recurrence and reoperation. After reconstruction of time-to-event data for the individual survival analysis, pooled Kaplan-Meier curves for the end points were generated. A total of 14 studies (5,565 patients) were included in the analysis. The respect approach was associated with superior survival compared with the resect approach in the overall sample (hazard ratio [HR] 0.73, 95% confidence interval [CI] 0.56 to 0.96, p = 0.024, n = 3,901 patients) but not in the risk-adjusted sample (HR 1.00, 95% CI 0.55 to 1.82, p = 0.991, n = 620 patients). There was no difference between the approaches in the rate of MR recurrence in the overall sample (HR 1.39, 95% CI 0.92 to 2.08, p = 0.116, n = 1,882 patients) or in the risk-adjusted sample (HR 1.62, 95% CI 0.76 to 3.47, p = 0.211, n = 288 patients). The data for reoperation were only available in the overall sample and did not reveal a difference (HR 0.92, 95% CI 0.62 to 1.35, p = 0.663, n = 3,505 patients). In conclusion, the current evidence suggests no difference in long-term mortality, MR recurrence, or reoperation between the resect and respect approaches for MVr after adjusting for patient risk factors. More long-term follow-up data are warranted.

Midterm Survival of Low-Risk Patients Treated With Transcatheter Versus Surgical Aortic Valve Replacement: Meta-Analysis of Reconstructed Time-to-Event Data.

Background We performed a meta-analysis of reconstructed time-to-event data from randomized controlled trials (RCTs) and propensity-score matched (PSM) studies comparing transcatheter versus surgical aortic valve replacement (TAVR versus SAVR) to evaluate midterm outcomes in patients considered low risk for SAVR. Methods and Results Study-level meta-analysis of reconstructed time-to-event data from Kaplan-Meier curves of RCTs and PSM studies published by December 31, 2022 was conducted. Eight studies (3 RCTs, 5 PSM studies) met our eligibility criteria and included 5444 patients; 2639 patients underwent TAVR, and 2805 patients underwent SAVR. TAVR showed a higher risk of all-cause mortality at 8 years of follow-up (hazard ratio [HR] 1.22, [95% CI, 1.03-1.43], P=0.018). Up to 2 years of follow-up, TAVR was not inferior to SAVR (HR, 1.08 [95% CI, 0.89-1.31], P=0.448); however, we observed a statistically significant difference after 2 years with higher mortality with TAVR (HR, 1.51 [95% CI, 1.14-2.00]; P=0.004). This difference was driven by PSM studies; our sensitivity analysis showed a statistically significant difference between TAVR and SAVR when we included only PSM studies (HR, 1.41 [95% CI, 1.16-1.72], P=0.001) but no statistically significant difference when we included only RCTs (HR, 0.89 [95% CI, 0.69-1.16], P=0.398). Conclusions In comparison with TAVR, SAVR appeared to be associated with improved survival beyond 2 years in low-risk patients. However, the survival benefit of SAVR was observed only in PSM studies and not in RCTs. The addition of data from ongoing RCTs as well as longer follow-up in previous RCTs will help to confirm if there is a difference in mid- and long-term survival between TAVR versus SAVR in the low-risk population.

Surgical Ablation for Atrial Fibrillation During Mitral Valve Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Although surgical ablation has been shown to produce excellent outcomes at follow-up for patients with atrial fibrillation who underwent mitral valve replacement/repair (MVR), this procedure is not commonly performed. Our objective was to conduct a systematic review and meta-analysis to evaluate the outcomes of concomitant surgical ablation during MVR. Three databases were systematically reviewed for randomized clinical trials published by August 2022. The primary outcome was sinus rhythm (SR) at 12 months. Secondary outcomes included SR at discharge and 6 months, all-cause mortality, permanent pacemaker implantation, and stroke and thromboembolic events. A random-effects meta-analysis was performed, calculating odds ratios (ORs) for each outcome. Thirteen studies were included, involving 1,089 patients comparing patients who underwent either isolated MVR ("MVR-only") or concomitant surgical ablation during MVR ("MVR+Ablation"). The odds of SR were significantly higher in the MVR+Ablation group at discharge (OR 9.62, 95% confidence interval [CI] 4.87 to 19.02, I2 = 55%), at 6-month follow-up (OR 7.21, 95% CI 4.30 to 12.11, I2 = 34%), and at 1-year follow-up (OR 8.41, 95% CI 5.14 to 13.77, I2 = 48%). All-cause mortality was not different in the groups, as were stroke and thromboembolic events, whereas the odds of permanent pacemaker implantation were slightly higher in the MVR+Ablation group (OR 1.87, 95% CI 1.11 to 3.17, I2 = 0%). Concomitant surgical ablation during MVR showed excellent outcomes at short-term follow-up, despite a slightly higher rate of permanent pacemaker implantation. Further studies with longer follow-ups are needed to assess if the SR is maintained over the years.

Long-Term Outcomes of Patients Undergoing Aortic Root Replacement With Mechanical Versus Bioprosthetic Valves: Meta-Analysis of Reconstructed Time-to-Event Data.

Background An aspect not so clear in the scenario of aortic surgery is how patients fare after composite aortic valve graft replacement (CAVGR) depending on the type of valve (bioprosthetic versus mechanical). We performed a study to evaluate the long-term outcomes of both strategies comparatively. Methods and Results Pooled meta-analysis of Kaplan-Meier-derived time-to-event data from studies with follow-up for overall survival (all-cause death), event-free survival (composite end point of cardiac death, valve-related complications, stroke, bleeding, embolic events, and/or endocarditis), and freedom from reintervention. Twenty-three studies met our eligibility criteria, including 11 428 patients (3786 patients with mechanical valves and 7642 patients with bioprosthetic valve). The overall population was mostly composed of men (mean age, 45.5-75.6 years). In comparison with patients who underwent CAVGR with bioprosthetic valves, patients undergoing CAVGR with mechanical valves presented no statistically significant difference in the risk of all-cause death in the first 30 days after the procedure (hazard ratio [HR], 1.24 [95% CI, 0.95-1.60]; P=0.109), but they had a significantly lower risk of all-cause mortality after the 30-day time point (HR, 0.89 [95% CI, 0.81-0.99]; P=0.039) and lower risk of reintervention (HR, 0.33 [95% CI, 0.24-0.45]; P<0.001). Despite its increased risk for the composite end point in the first 6 years of follow-up (HR, 1.41 [95% CI, 1.09-1.82]; P=0.009), CAVGR with mechanical valves is associated with a lower risk for the composite end point after the 6-year time point (HR, 0.46 [95% CI, 0.31-0.67]; P<0.001). Conclusions CAVGR with mechanical valves is associated with better long-term outcomes in comparison with CAVGR with bioprosthetic valves.

Knowledge of Child Abuse and Neglect among General Practitioners and Pediatricians in Training: A Survey.

Child abuse and neglect is a common, underreported, and worldwide problem. Health care providers play an important role in detecting and reporting this problem. This study examined the knowledge on the clinical signs and mimickers of child abuse among Belgian trainees in family medicine and pediatrics. Participants filled out an anonymous online survey of 15 fictional but realistic cases with either suspicious or non-suspicious signs of abuse or neglect in the context of primary or emergency care. The overall score on all cases, the number of correct answers per case, and the median score were calculated, and the association of the participant's demographic characteristics with their score was examined using regression analysis. A total of 70 participants completed the survey. The overall median score was 73.3% (IQR 20.0%). The suspicious cases were solved more correctly than the non-suspicious cases (median: 85.7% versus 62.5%, p < 0.001). Regression analysis could not reveal a significant association of type and level of education with the performance on the survey. Knowledge of the clinical signs of child maltreatment among pediatricians and general practitioners in training is good, but there is still room for improvement.

Gastrointestinal syndromes preceding a diagnosis of Parkinson's disease: testing Braak's hypothesis using a nationwide database for comparison with Alzheimer's disease and cerebrovascular diseases.

OBJECTIVE: Braak's hypothesis states that Parkinson's disease (PD) originates in the gastrointestinal (GI) tract, and similar associations have been established for Alzheimer's disease (AD) and cerebrovascular diseases (CVD). We aimed to determine the incidence of GI syndromes and interventions preceding PD compared with negative controls (NCs), AD and CVD. DESIGN: We performed a combined case-control and cohort study using TriNetX, a US based nationwide medical record network. Firstly, we compared subjects with new onset idiopathic PD with matched NCs and patients with contemporary diagnoses of AD and CVD, to investigate preceding GI syndromes, appendectomy and vagotomy. Secondly, we compared cohorts with these exposures to matched NCs for the development of PD, AD and CVD within 5 years. RESULTS: We identified 24 624 PD patients in the case-control analysis and matched 18 cohorts with each exposure to their NCs. Gastroparesis, dysphagia, irritable bowel syndrome (IBS) without diarrhoea and constipation showed specific associations with PD (vs NCs, AD and CVD) in both the case-control (odds ratios (ORs) vs NCs 4.64, 3.58, 3.53 and 3.32, respectively, all p<0.0001) and cohort analyses (relative risks (RRs) vs NCs 2.43, 2.27, 1.17 and 2.38, respectively, all p<0.05). While functional dyspepsia, IBS with diarrhoea, diarrhoea and faecal incontinence were not PD specific, IBS with constipation and intestinal pseudo-obstruction showed PD specificity in the case-control (OR 4.11) and cohort analysis (RR 1.84), respectively. Appendectomy decreased the risk of PD in the cohort analysis (RR 0.48). Neither inflammatory bowel disease nor vagotomy were associated with PD. CONCLUSION: Dysphagia, gastroparesis, IBS without diarrhoea and constipation might specifically predict Parkinson's disease.

Impact of Valve Academic Research Consortium 3 (VARC-3) minor access site vascular complications in patients undergoing percutaneous transfemoral transcatheter aortic valve implantation.

OBJECTIVES: The aim of this study was to investigate the impact of Valve Academic Research Consortium 3 minor access site vascular complications (VCs) in patients who underwent percutaneous transfemoral (TF) transcatheter aortic valve implantation (TAVI). METHODS: This single-centre retrospective study included consecutive patients who underwent percutaneous TF-TAVI from 2009 to 2021. A propensity score-matched analysis was performed to compare early and long-term clinical results between patients with VC and without VC (nVC). RESULTS: A total of 2161 patients were included, of whom 284 (13.1%) experienced access site VC. Propensity score analysis allowed to match 270 patients from the VC group with 727 patients from the nVC group. In the matched cohorts, the VC group showed longer operative times (63.5 vs 50.0 min, P < 0.001), higher operative and in-hospital mortality (2.6% vs 0.7%, P = 0.022; and 6.3% vs 3.2%, P = 0.040, respectively), longer hospital length of stay (8 vs 7 days, P = 0.001) and higher rates of blood transfusion (20.4% vs 4.3%, P < 0.001) and infectious complications (8.9% vs 3.8%, P = 0.003). Overall survival during follow-up was significantly lower in the VC group (hazard ratio 1.37, 95% CI 1.03-1.82, P = 0.031) with 5-year survival rates being 58.0% (95% CI 49.5-68.0%) and 70.7% (95% CI 66.2-75.5%) for the VC and nVC groups, respectively. CONCLUSIONS: This retrospective study observed that minor access site VCs during percutaneous TF-TAVI can be serious events affecting early and long-term outcomes.

Long-term outcomes of valve-sparing aortic root versus composite aortic valve graft replacement for aortic root aneurysm: Meta-analysis of reconstructed time-to-event data.

BACKGROUND: We aimed to evaluate the long-term outcomes of valve-sparing aortic root replacement (VSARR) versus composite aortic valve graft replacement (CAVGR) for aortic root aneurysms. METHODS: Meta-analysis of Kaplan-Meier-derived time-to-event data from studies with follow-up including propensity-score matching or propensity-score adjustment. RESULTS: Six studies met our eligibility criteria, comprising 3215 patients (1770 patients treated with VSARR and 1445 patients with CAVGR). We observed a statistically significant difference for overall survival favoring VSARR (HR 0.63, 95%CI 0.49-0.82, P â€‹= â€‹0.001), but no statistically significant difference in the risk of reoperation (HR 0.77, 95%CI 0.51-1.14, P â€‹= â€‹0.187) in the overall follow-up. Landmark analyses revealed that, in the first 10 years after the procedure, reoperation rates were comparable between VSARR and CAVGR (HR 0.96, 95%CI 0.62-1.48, p â€‹= â€‹0.861), but the results beyond 10 years showed improved rates of freedom from reoperation in patients undergoing VSARR (HR 0.10, 95%CI 0.01-0.78; p â€‹= â€‹0.027). CONCLUSION: VSARR seems to confer better long-term survival and lower risk of reoperation in the follow-up of patients treated for aortic root aneurysm when compared with CAVGR.

Midterm Outcomes of Endovascular vs. Medical Therapy for Uncomplicated Type B Aortic Dissection: Meta-Analysis of Reconstructed Time to Event Data.

OBJECTIVE: To evaluate outcomes of thoracic endovascular aortic repair (TEVAR) vs. medical therapy in uncomplicated type B aortic dissections (TBAD). DATA SOURCES: PubMed/MEDLINE, EMBASE, SciELO, LILACS, CENTRAL/CCTR, Google Scholar, and reference lists of relevant articles. REVIEW METHODS: This was a pooled meta-analysis of time to event data extracted from studies published by December 2022 for the following outcomes: all cause mortality, aortic related mortality, and late aortic interventions. Certainty of evidence was evaluated through the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool. RESULTS: Ten studies met the eligibility criteria (eight observational; two randomised trials), comprising 17 906 patients (2 332 patients in the TEVAR groups and 15 574 patients in the medical therapy group). Compared with patients who received medical therapy, patients who underwent TEVAR had a statistically significantly lower risk of all cause death (HR 0.79, 95% CI 0.72 - 0.87, p < .001; GRADE certainty: low) and lower risk of aortic related death (HR 0.43, 95% CI 0.30 - 0.62, p < .001; GRADE certainty: low) without statistically significant difference in the risk of late aortic interventions (HR 1.05, 95% CI 0.88 - 1.26, p = .56; GRADE certainty: low). In the subgroup analyses, TEVAR was associated with lower risk of all cause death when randomised controlled trials only were pooled (HR 0.44, 95% CI 0.23 - 0.83, p = .012; GRADE certainty: moderate), younger patients only (HR 0.56, 95% CI 0.47 - 0.67, p < .001; GRADE certainty: low), Western populations only (HR 0.85, 95% CI 0.77 - 0.93, p = .001; GRADE certainty: low) and non-Western populations only (HR 0.47, 95% CI 0.35 - 0.62, p < .001; GRADE certainty: low). For all cause mortality and aortic related mortality, restricted mean survival time was overall 396 days and 398 days longer with TEVAR (p < .001), respectively, which means that TEVAR was associated with lifetime gain. CONCLUSION: TEVAR may be associated with better midterm survival and lower risk of aortic related death in the follow up of patients treated for uncomplicated TBAD compared with medical therapy; however, randomised controlled trials with larger sample sizes and longer follow up are still warranted.
