RESUMO

Purpose: To study the effect of rosuvastatin 40 mg (initiated 7 days prior to surgery) in patients undergoing valve replacement (VR) for rheumatic mitral valve disease on left ventricular (LV) strain and biomarker release kinetics. Methods: In this randomized study, cardiac biomarkers viz. troponin I (TnI), Creatine kinase MB (CK-MB), N-terminal pro B-type natriuretic peptide (NTPBNP) were measured before surgery; and 8, 24 and 48 h postoperatively. Global LV (circumferential, global circumferential strain (GCS); longitudinal, GLS; radial, global radial strain (GRS)) strains were measured preoperatively; and 48 h and 30 days postoperatively. Results: Following VR, Global Longitudinal Strain (GLS), Global Circumferential Strain (GCS) and Global Radial Strain (GRS) declined at 48 h in both statin loaded (SL) and non loaded (NL) groups. The %decline in strain was significantly lower in SL group (% change in GLS 35.8% vs 38.8%, GCS 34% vs 44.1%, GRS 45.7% vs 52.6%; p < 0.001).All strain values improved at 30 days with higher improvement in SL group (GLS -15.92 ± 2.00% vs -12.6 ± 1.66%, GCS -15.12 ± 2.93% vs -13.04 ± 2.44%; GRS 22.12 ± 6.85% vs 19.32 ± 6.48%). While TnI, CKMB, NTPBNP increased following surgery, values at 8, 24 and 48 h were lower in the SL vs. NL group. Mean change (baseline to peak biomarker value) was also significantly lower in SL group.The SL group had shorter hospital and Intensive Care Unit (ICU) stay. On Receiver Operating Characteristic Curve (ROC) analysis, baseline GCS ≤ 14% best predicted postoperative 30 day Left Ventricular Ejection Fraction (LVEF) ≤ 50%. Conclusion: Pre-operative high dose rosuvastatin was "cardioprotective" with favorable effect on LV global strain and release kinetics of biomarkers. These cut-offs (described for the first time for rheumatic VR) can be used as prognostic predictors.

RESUMO

Tricuspid valve disease is an often underrecognized clinical problem that is associated with significant morbidity and mortality. Unfortunately, patients will often present late in their disease course with severe right-sided heart failure, pulmonary hypertension, and life-limiting symptoms that have few durable treatment options. Traditionally, the only treatment for tricuspid valve disease has been medical therapy or surgery; however, there have been increasing interest and success with the use of transcatheter tricuspid valve therapies over the past several years to treat patients with previously limited therapeutic options. The tricuspid valve is complex anatomically, lying adjacent to important anatomic structures such as the right coronary artery and the atrioventricular node, and is the passageway for permanent pacemaker leads into the right ventricle. In addition, the mechanism of tricuspid pathology varies widely between patients, which can be due to primary, secondary, or a combination of causes, meaning that it is not possible for 1 type of device to be suitable for treatment of all cases of tricuspid valve disease. To best visualize the pathology, several modalities of advanced cardiac imaging are often required, including transthoracic echocardiography, transesophageal echocardiography, cardiac computed tomography, and cardiac magnetic resonance imaging, to best visualize the pathology. This detailed imaging provides important information for choosing the ideal transcatheter treatment options for patients with tricuspid valve disease, taking into account the need for the lifetime management of the patient. This review highlights the important background, anatomic considerations, therapeutic options, and future directions with regard to treatment of tricuspid valve disease.

RESUMO

OBJECTIVES: Randomized controlled trials comparing transcatheter aortic valve implantation with surgical aortic valve replacement demonstrate conflicting evidence, particularly in low-risk patients. We aim to reevaluate the evidence using trial sequential analysis, balancing type I and II errors, and compare with conventional meta-analysis. METHODS: Databases were searched for randomized controlled trials, which were divided into higher-risk and lower-risk randomized controlled trials according to a pragmatic risk classification. Primary outcomes were death and a composite end point of death or disabling stroke assessed at 1 year and maximum follow-up. Conventional meta-analysis and trial sequential analysis were performed, and the required information size was calculated considering a type I error of 5% and a power of 90%. RESULTS: Eight randomized controlled trials (n = 5274 higher-risk and 3661 lower-risk patients) were included. Higher-risk trials showed no significant reduction in death at 1 year with transcatheter aortic valve implantation (relative risk, 0.93, 95% CI, 0.81-1.08, P = .345). Lower-risk trials suggested lower death risk on conventional meta-analysis (relative risk, 0.67, 95% CI, 0.47-0.96, P = .031), but trial sequential analysis indicated potential spurious evidence (P = .116), necessitating more data for conclusive benefit (required information size = 5944 [59.8%]). For death or disabling stroke at 1 year, higher-risk trials lacked evidence (relative risk, 0.90, 95% CI, 0.79-1.02, P = .108). In lower-risk trials, transcatheter aortic valve implantation indicated lower risk in conventional meta-analysis (relative risk, 0.68, 95% CI, 0.50-0.93, P = .014), but trial sequential analysis suggested potential spurious evidence (P = .053), necessitating more data for conclusive benefit (required information size = 5122 [69.4%]). Follow-up results provided inconclusive evidence for both primary outcomes across risk categories. CONCLUSIONS: Conventional meta-analysis methods may have prematurely declared an early reduction of negative outcomes after transcatheter aortic valve implantation when compared with surgical aortic valve replacement.

RESUMO

Purpose: : Endotension is a rare late complication characterized by an increase in sac size without any type of endoleak following endovascular aortic aneurysm repair (EVAR). Due to its rarity, few studies have demonstrated the mechanism behind and the management of endotension. In this study, we aimed to better understand the treatment and the long-term outcome of endotension in a single-center cohort. Materials and Methods: : This study was designed for a retrospective review of the patients diagnosed with endotension between January 2006 and December 2017. The study patients were categorized into two groups (primary versus secondary) based on the presence of any type of endoleak before the diagnosis of endotension. We collected data related to endotension treatment, intraoperative findings, and long-term outcomes. Results: : In a cohort of 15 patients diagnosed with endotension following EVAR, eight were classified into the primary endotension (PE) group without prior endoleak, and seven exhibited secondary endotension (SE). Among the eight PE patients, endovascular intervention for a preemptive purpose was conducted in six patients; however, three (50%) showed continuous sac expansion and finally received open conversion. Overall, eight patients (five in PE and three in SE) underwent open conversion, and one (12.5%) presented with an undetected endoleak during the operative findings. Postoperative morbidity was observed in three patients with no operative mortality. Conclusion: : Endotension can be managed initially through simple observation for changes on serial images, along with preemptive endovascular intervention. However, surgical intervention should be considered for patients with specific indications including continuous aneurysm sac enlargement, presence of symptoms, suspicions of migration of stent-graft with endoleak, and infection.

RESUMO

BACKGROUND: Infective endocarditis continues to be a significant concern and may be undergoing an epidemiological transition. METHODS: Were studied 1804 consecutive episodes of infective endocarditis between 1978 and 2022. The mean age was 48 ( ± 19), and 1162 (64%) patients were male. Temporal trends in demographic data, comorbidities, predisposing conditions, microorganisms, complications and in-hospital death have been studied over the decades (1978-1988, 1989-1999, 2000-2010 and 2011-2022). The outcomes and clinical characteristics were modeled using nonlinear cubic spline functions. FINDINGS: Valve surgery was performed in 50% of the patients and overall in-hospital mortality was 30%. From the first to the fourth decade studied, the average age of patients increased from 29 to 57 years (p < 0.001), with significant declines in the occurrence of rheumatic valvular heart disease (15% to 6%; p < 0.001) and streptococcal infections (46% to 33%; p < 0.001). Healthcare-associated infections have increased (9% to 21%; p < 0.001), as have prosthetic valve endocarditis (26% to 53%; p < 0.001), coagulase-negative staphylococcal infections (4% to 11%; p < 0.001), and related-complications (heart failure, embolic events, and perivalvular abscess; p < 0.001). These changes were associated with a decline in adjusted in-hospital mortality from 34% to 25% (p = 0.019). INTERPRETATION: In the 44 years studied, there was an increase in the mean age of patients, healthcare-related, prosthetic valve, coagulase-negative staphylococci/MRSA infections, and related complications. Notably, these epidemiological changes were associated with a decline in the adjusted in-hospital mortality.

RESUMO

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.

RESUMO

INTRODUCTION: The objective of this study was to assess the rates of surgical shunting and prosthesis placement for acute ischemic priapism using a large multi-institutional claims database. METHODS: A US claims database network (TriNetX Diamond Network) was queried from 2010 to 2020. We constructed a cohort of men ages ≥ 16 years who (1) had a diagnosis of priapism and (2) underwent an irrigation of the corpora cavernosa for priapism. We assessed the number of men who then had a surgical penile shunt or penile prosthesis placement. Demographics, time to surgical procedure, and order of procedures were collected. RESULTS: A total of 6392 men were identified with the diagnosis of priapism and the procedure of corpora cavernosal irrigation. Of these men, 693 (11%) proceeded to surgical shunt. One hundred forty-four men (2%) underwent initial penile prosthesis placement. Of the men undergoing initial penile prosthesis, only 17 of 144 (12%) cases occurred within the first month of corpora cavernosal irrigation. Finally, when assessing choice of initial shunts vs initial penile prosthesis before and after 2015, overall rates of initial shunt (10.0% vs 8.5%, P < .0001) and initial prosthesis (3.1% vs 2.1%, P < .0001) were lower after 2015 when compared with rates prior to 2015. CONCLUSIONS: In this US claims-based analysis of men presenting with ischemic priapism and treated with initial irrigation, a small percentage (11%) of men went on to receive surgical shunting, and only 2% received an initial prosthesis. Men receiving initial prostheses were more likely to have more comorbidities, and overall surgical management of priapism has decreased over time.

RESUMO

Proximal femoral fractures occur at an annual incidence of approximately 200/100,000 inhabitants and mortality rates range up to 30% especially in geriatric patients where complications are not necessarily associated to surgery. In nearly all cases surgical treatment is required. Procedures to preserve the femoral head have to be performed as early as possible (as specified by the Federal Joint Committee, GBA, within 24 h). For joint-preserving approaches in medial femoral neck fractures a time to surgery within 6 h is considered to be advantageous. Perioperative patient care is of high importance regarding the prevention of pneumonia, renal failure, delirium and further complications. Postoperatively full weight bearing enables for early mobilization and prevention of surgery-related complications. Nonunions, avascular necrosis of the femoral head, cut-out and prosthetic dislocation must be avoided by the selection of the appropriate procedure. Minimally displaced femoral neck fractures are primarily treated by osteosynthesis and conservative management is only considered in isolated cases. For displaced femoral neck fractures, factors such as a young biological age with high activity levels, the absence of arthritis and good bone quality with a successful reduction favor for a femoral head-preserving osteosynthesis. Otherwise, (hybrid) total hip replacement (THR) is the preferred method for unstable and displaced fractures, whereby hemiarthroplasty should only be considered for very old and patients with pre-existing diseases. Fractures in the trochanteric region are treated with a proximal femoral nail and subtrochanteric fractures are managed using a long proximal femoral nail. To avoid secondary complications, the choice of optimal treatment should be based on a good understanding of the injury pattern, biomechanical and technical aspects of each procedure.

RESUMO

Background: The significance of geographic barriers to receiving inflatable penile prosthesis (IPP) treatment is uncertain according to the existing medical literature. Aim: To describe the travel patterns of men with erectile dysfunction (ED) in the United States who underwent IPP surgery. Methods: This retrospective cohort study utilized data from the 100% Medicare Standard Analytical Files. Men aged ≥65 years with an ED diagnosis who underwent IPP surgery between January 2016 and December 2021 were identified from the database. Federal Information Processing Series codes from the National Bureau of Economic Research's County Distance Database were used to determine geographic distances from patients' homes to the facilities at which surgery was performed. Outcomes: Evaluations included the proportions of men who traveled outside their county of residence or state for IPP treatment and the average distances in miles traveled. Results: Among 15 954 men with ED undergoing IPP treatment, 56.4% received care out of their county for IPP, at a mean distance of 125.6 miles (range, 3.8-4935.0). Although patients aged ≥80 years were less likely to travel outside their county as compared with men aged 65 to 69 years (48.1% vs 57.1%, P < .001), if they traveled, they were likely to travel farther (mean, 171.8 vs 117.7 miles; P < .001). South Dakota had the highest proportion of men traveling outside their county for IPP treatment (91.3%; mean, 514.2 miles), while Vermont had the highest proportion traveling outside their home state (73.7%). Clinical Implications: By unveiling disparities in access, this study will potentially lead to tailored interventions that enhance patient care and health outcomes. Strengths and Limitations: Strengths include the uniqueness in (1) evaluating the proportions of patients who travel out of their county of residence or home state for IPP treatment and (2) quantifying the average distances that patients traveled. An additional strength is the large sample size due to the retrospective design and database used. The analysis did not capture all Medicare enrollees; however, it did encompass all traditional Medicare enrollees, representing approximately half of all men in the US aged ≥65 years. Limitations include not being generalizable to entire population of the US, as the study examined only Medicare enrollees. In addition, the study period includes the pandemic, which could have affected travel patterns. Furthermore, the coding and accuracy of the data are limitations of using administrative claims data for research. Conclusion: Study findings showed that many men with Medicare and ED traveled from their home geographic location for IPP treatment.

RESUMO

This case report explores a unique presentation of hip dysplasia in a female patient aged 21 years old diagnosed with Charcot-Marie-Tooth disease (CMT) type 1A and multiple acyl-CoA dehydrogenase deficiency (MADD). The coexistence of these neuromuscular and metabolic disorders in a patient with hip dysplasia provides an opportunity to investigate their potential interactions and impact on diagnosis, treatment, and prognosis. The patient underwent labral repair with shelf osteotomy and later a total hip replacement. This case highlights the need for further research to better understand the relationships between CMT, MADD, neuromuscular dysplasia, and hip dysplasia. A deeper understanding of these interactions may lead to improved diagnostic techniques, earlier intervention, and personalized treatment approaches for patients with co-morbid conditions, ultimately improving patient outcomes and reducing complications later in life.

RESUMO

BACKGROUND: A quarter of patients with severe aortic stenosis (AS) were asymptomatic, and only a third of them survived at the end of 4 years. Only a select subset of these patients was recommended for aortic valve replacement (AVR) by the current American College of Cardiology/American Heart Association guidelines. We intended to study the effect of early AVR (eAVR) in this subset of asymptomatic patients with preserved left ventricle function. METHODS AND RESULTS: We searched PubMed and Embase for randomised and observational studies comparing the effect of eAVR versus conservative therapy in patients with severe, asymptomatic AS and normal left ventricular function. The primary outcome was all-cause mortality. The secondary outcomes were composite major adverse cardiac events (MACE) (study defined), myocardial infarction (MI), stroke, cardiac death, sudden death, the development of symptoms, heart failure hospitalisations and major bleeding. We used GRADEPro to assess the certainty of the evidence. In the randomised controlled trial (RCT) only analysis, we found no significant difference in all-cause mortality between the early aortic intervention group versus the conservative arm (CA) (incidence rate ratio, IRR (CI): 0.5 (0.2 to 1.1), I2=31%, p=0.09). However, in the overall cohort, we found mortality benefit for eAVR over CA (IRR (CI): 0.4 (0.3 to 0.7), I2=84%, p<0.01). There were significantly lower MACE, cardiac death, sudden death, development of symptoms and heart failure hospitalisations in the eAVR group. We noticed no difference in MI, stroke and major bleeding. CONCLUSION: We conclude that there is no reduction in all-cause mortality in the eAVR arm in patients with asymptomatic AS with preserved ejection fraction. However, eAVR reduces heart failure related hospitalisations and death or heart failure hospitalisations. PROSPERO REGISTRATION NUMBER: CRD42022306132.

RESUMO

AIM: To assess outcomes after cardiac surgery with biological valve replacement, valve repair or transcatheter aortic valve implantation (TAVI) in patients with atrial fibrillation (AF) in accordance with oral anticoagulant (OAC) treatment. METHODS: All patients in Sweden undergoing valvular intervention with AF were included. Associations between OAC exposure and cardiovascular (CV) events (composite of CV death, ischaemic stroke or systemic embolism) and major bleeding were investigated using Cox regression analysis. The analysis was separated in time periods of 0-3 and 3-12 months after discharge. RESULTS: 4730 patients were included in the first time period, 54.0% had received a surgical biological valve prosthesis, 23.8% valve repair and 22.2% TAVI. Exposure to warfarin (comparator) was 62.3%, to non-vitamin K antagonist oral anticoagulants (NOACs) 10.0% and to no OAC 27.7%. NOAC exposure was associated with similar risk of the composite CV outcome and major bleeding from 0 to 3 months. No OAC was associated with increased risk of the composite CV outcome (HR 1.71; 95% CI 1.26 to 2.32) and similar risk of major bleeding. Further analysis of the bioprosthetic valve replacement subgroup indicated increased risk of CV death when exposed to NOAC (HR 2.58; 95% CI 1.15 to 5.78) and no OAC (HR 2.82; 95% CI 1.65 to 4.82) compared with warfarin from 0 to 3 months. No differences were seen between 3 and 12 months. CONCLUSION: In this registry-based cohort study of patients with AF with severe valvular heart disease undergoing various valvular interventions, NOAC appears to be comparable with warfarin regarding efficacy and safety. Patients not receiving OAC had higher risk of CV events. NOAC was associated with increased CV death compared with warfarin in the surgical bioprosthetic valve replacement subgroup, illustrating the importance of being cautious when extrapolating data from one patient group to another. Further studies comparing NOAC and warfarin in the early postoperative phase are warranted, especially following surgical bioprosthetic valve replacement.

RESUMO

OBJECTIVES: Lipoprotein(a) (Lp(a)) is associated with an increased incidence of native aortic stenosis, which shares similar pathological mechanisms with bioprosthetic aortic valve (bAV) degeneration. However, evidence regarding the role of Lp(a) concentrations in bAV degeneration is lacking. This study aims to evaluate the association between Lp(a) concentrations and bAV degeneration. METHODS: In this retrospective multicentre study, patients who underwent a bAV replacement between 1 January 2010 and 31 December 2020 and had a Lp(a) measurement were included. Echocardiography follow-up was performed to determine the presence of bioprosthetic valve degeneration, which was defined as an increase >10 mm Hg in mean gradient from baseline with concomitant decrease in effective orifice area and Doppler Velocity Index, or new moderate/severe prosthetic regurgitation. Levels of Lp(a) were compared between patients with and without degeneration and Cox regression analysis was performed to investigate the association between Lp(a) levels and bioprosthetic valve degeneration. RESULTS: In total, 210 cases were included (mean age 74.1±9.4 years, 72.4% males). Median time between baseline and follow-up echocardiography was 4.4 (IQR 3.7) years. Bioprostheses degeneration was observed in 33 (15.7%) patients at follow-up. Median serum levels of Lp(a) were significantly higher in patients affected by degeneration versus non-affected cases: 50.0 (IQR 72.0) vs 15.6 (IQR 48.6) mg/dL, p=0.002. In the regression analysis, high Lp(a) levels (≥30 mg/dL) were associated with degeneration both in a univariable analysis (HR 3.6, 95% CI 1.7 to 7.6, p=0.001) and multivariable analysis adjusted by other risk factors for bioprostheses degeneration (HR 4.4, 95% CI 1.9 to 10.4, p=0.001). CONCLUSIONS: High serum Lp(a) is associated with bAV degeneration. Prospective studies are needed to confirm these findings and to investigate whether lowering Lp(a) levels could slow bioprostheses degradation.

RESUMO

Valve-in-valve (ViV) transcatheter aortic valve implantation (ViV-TAVI) in patients with failed bioprostheses arose as an alternative to redo surgical aortic valve replacement (SAVR). To evaluate all-cause mortality in ViV-TAVI versus redo-SAVR, we performed a study-level meta-analysis of reconstructed time-to-event data from Kaplan-Meier curves of nonrandomized studies published by August 2023. A total of 16 studies met our eligibility criteria, with a total of 4,373 patients (2,204 patients underwent ViV-TAVI and 2,169 patients underwent redo-SAVR). Pooling all the studies, ViV-TAVI showed a lower risk of all-cause mortality in the first 6 months (hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.46 to 0.73, p <0.001), with an HR reversal after this time point favoring redo-SAVR (HR 1.92, 95% CI 1.58 to 2.33, p <0.001). Pooling only the matched populations (which represented 64.6% of the overall population), ViV-TAVI showed a lower risk of all-cause mortality in the first 6 months (HR 0.56, 95% CI 0.43 to 0.73, p <0.001], with a reversal after 6 months favoring redo-SAVR (HR 1.55, 95% CI 1.25 to 1.93, p <0.001). The meta-regression analyses revealed a modulating effect of the following covariates: age, coronary artery disease, history of coronary artery bypass graft surgery, and implanted valves <25 mm. In conclusion, ViV-TAVI is associated with better survival immediately after the procedure than redo-SAVR; however, this primary advantage reverses over time, and redo-SAVR seems to offer better survival at a later stage. Because these results are pooled data from observational studies, they should be interpreted with caution, and randomized controlled trials are warranted.

RESUMO

Aim: This study aimed to review the scientific literature to describe the main care and hygiene protocols for different types of maxillofacial prostheses (MFP). Methods: A bibliographic search on the PubMed / Medline database using the following keywords: ["maxillofacial prosthesis" OR "ocular prostheses" OR "palatal obturators"] AND ["Cleaning" OR "disinfection"] AND ["care"] AND ["color stability"] OR ["denture cleansers" OR "cleansing agents"]. Articles addressing materials, cleaning and disinfection protocols, and care related to MFP were included. The following exclusion criteria were applied: no adequate methodology, incompatibility with the area of interest, and unavailability for reading in full. Results: The papers were grouped into the following topics: facial prostheses, ocular prostheses, maxillofacial intraoral prostheses, and retention systems. Conclusion: Despite the MFP changes over time, its degradation decreases upon following the recommendations and post-adaptation care. The guidelines for cleaning and disinfection must be individualized to guarantee the longevity of the prosthesis and the patient health

RESUMO

ABSTRACT In this article, we present the case of a 47-year-old man who underwent Bentall-Bono procedure and frozen elephant trunk prosthesis implantation due to severe aortic regurgitation and aortic dilatation with a second-time endovascular stent-graft repair in descending aorta. Over eight years, a subacute graft infection by Propionibacterium acnes was developed, culminating in cardiogenic shock secondary to severe aortic regurgitation due to a complete aortic root dehiscence because of multiple aortic pseudoaneurysms. The patient underwent emergency surgery in which the replacement of the graft by a biological valve tube was performed accompanied by a complete debranching of the three supra-aortic vessels.

RESUMO

OBJECTIVES: Grading the severity of moderate mixed aortic stenosis and regurgitation (MAVD) is challenging and the disease poorly understood. Identifying markers of haemodynamic severity will improve risk stratification and potentially guide timely treatment. This study aims to identify prognostic haemodynamic markers in patients with moderate MAVD. METHODS: Moderate MAVD was defined as coexisting moderate aortic stenosis (aortic valve area (AVA) 1.0-1.5 cm2) and moderate aortic regurgitation (vena contracta (VC) 0.3-0.6 cm). Consecutive patients diagnosed between 2015 and 2019 were included from a multicentre registry. The primary composite outcome of death or heart failure hospitalisation was evaluated among these patients. Demographics, comorbidities, echocardiography and treatment data were assessed for their prognostic significance. RESULTS: 207 patients with moderate MAVD were included, aged 78 (66-84) years, 56% male sex, AVA 1.2 (1.1-1.4) cm2 and VC 0.4 (0.4-0.5) cm. Over a follow-up of 3.5 (2.5-4.7) years, the composite outcome was met in 89 patients (43%). Univariable associations with the primary outcome included older age, previous myocardial infarction, previous cerebrovascular event, atrial fibrillation, New York Heart Association >2, worse renal function, tricuspid regurgitation ≥2 and mitral regurgitation ≥2. Markers of biventricular systolic function, cardiac remodelling and transaortic valve haemodynamics demonstrated an inverse association with the primary composite outcome. In multivariable analysis, peak aortic jet velocity (Vmax) was independently and inversely associated with the composite outcome (HR: 0.63, 95% CI 0.43 to 0.93; p=0.021) in an adjusted model along with age (HR: 1.05, 95% CI 1.03 to 1.08; p<0.001), creatinine (HR: 1.002, 95% CI 1.001 to 1.003; p=0.005), previous cerebrovascular event (85% vs 42%; HR: 3.04, 95% CI 1.54 to 5.99; p=0.001) and left ventricular ejection fraction (LVEF) (HR: 0.97, 95% CI 0.95 to 0.99; p=0.007). Patients with Vmax ≤2.8 m/s and LVEF ≤50% (n=27) had the worst outcome compared with the rest of the population (72% vs 41%; HR: 3.87, 95% CI 2.20 to 6.80; p<0.001). CONCLUSIONS: Patients with truly moderate MAVD have a high incidence of death and heart failure hospitalisation (43% at 3.5 (2.5-4.7) years). Within this group, a high-risk group characterised by disproportionately low aortic Vmax (≤2.8 m/s) and adverse remodelling (LVEF ≤50%) have the worst outcomes.

RESUMO

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.
