Recurrence of valvular involvement in Libman-Sacks endocarditis associated with antiphospholipid syndrome: A case report.

Key Clinical Message: Recurrence of valvular involvement may occur after Libman-Sacks endocarditis surgery, emphasizing the need for frequent multivalvular evaluations with echocardiography or more sensitive methods to optimize surgical outcomes. Abstract: This report presented a 32-year-old woman, complaining of recurrent fever and chills. Physical examination revealed the presence of a third heart sound (S3), a pan-systolic murmur (III/VI) at mitral and tricuspid foci, tachycardia, and fine pulmonary crackles. Transesophageal echocardiography (TEE) revealed severe mitral regurgitation (MR) and moderate tricuspid regurgitation (TR) with vegetations on the mitral valve. Initially, intravenous antibiotic therapy was started simultaneously with diagnostic studies. Despite a positive TEE, negative blood cultures on three separate occasions precluded meeting the diagnostic criteria outlined in the modified Duke criteria. Moreover, the patient's condition continued to deteriorate after antibiotic therapy, leading to the diagnosis of Libman-Sacks endocarditis. The patient was considered a candidate for mitral valve surgery. All vegetations were completely debrided and then the mitral valve was reconstructed. Follow-up post-surgery echocardiography revealed the absence of MR and mitral stenosis (MS). Four months later, the patient presented again complaining of fatigue, dyspnea, lower extremity edema, and ascites with evidence of pulmonary hypertension and right heart failure on physical examination. TEE was performed, which revealed severe MR, severe TR, detached artificial chordae, and blood leak from the perforated pericardial patch. Therefore, she was necessitated for valvular surgery and underwent mitral and tricuspid valve surgery. The mitral ring and perforated pericardial patch were removed, and a mitral prosthetic valve was implanted. In addition, the tricuspid valve was repaired. Follow-up post-surgery echocardiography revealed the absence of MR and TR. To our knowledge, this is the first case of LSE recurrence with multi-valvular involvement.

Sydenham's Chorea in Children with Acute Rheumatic Fever: An Echocardiographic Survey of Pediatric Patients in Northwestern Iran.

Background: Although infrequent, Sydenham's chorea (SC) may occur as a result of injury to the basal ganglia in children with acute rheumatic fever (ARF) secondary to group A Streptococcal infection. Certain hallmarks of SC, such as movement disorders, could be utilized as a predictive marker for carditis. The present study aimed to investigate neurologic and cardiologic symptoms in children with suspected SC after ARF. Methods: All children aged 5-16 who were admitted at Shahid Madani Pediatric Hospital (Tabriz, Iran), with an initial diagnosis of ARF and SC between 2009 and 2022 were included for echocardiographic assessment and prospective follow-up within 6 and 12 months after the start point. The pattern and severity of valvulopathy, as well as the prevalence of Jones criteria for rheumatic fever, were used to assess the effect. The collected data were analyzed using SPSS Statistics software (version 22.0) using Chi square and Fisher's exact tests. P<0.05 was considered statistically significant. Results: The study enrolled 85 children, 36 girls and 49 boys, with a mean age of 9.7±2.7. On the first echocardiography, 42.4% of patients had mitral valve regurgitation (MR), with a predominance of female patients (P=0.04). Of those diagnosed with SC (12 girls and 6 boys), 66.7% showed cardiac involvement, with a higher prevalence of MR in both sexes (P=0.04). The pattern of cardiac involvement after 6 months was significantly different between the groups (P=0.04). However, no such difference was observed during the one-year follow-up (P=0.07). Female sex was found to have a significant relationship with SC localization (P=0.01). Conclusion: In addition to its neurological manifestations, SC can be associated with clinical or subclinical cardiac valve dysfunction that might last for more than a year. In addition to attempting early detection and appropriate management, a precise cardiac and neurologic assessment during admission and follow-up is recommended.A preprint version of this manuscript is available at DOI: 10.21203/rs.3.rs-772662/v1 (https://www.researchsquare.com/article/rs-772662/v1).

Treatments affecting splenic function as a risk factor for valvular heart disease in Childhood Cancer Survivors: A DCCSS-LATER study.

PURPOSE: Splenectomy might be a risk factor for valvular heart disease (VHD) in adult Hodgkin lymphoma survivors. As this risk is still unclear for childhood cancer survivors (CCS), the aim of this study is to evaluate the association between treatments affecting splenic function (splenectomy and radiotherapy involving the spleen) and VHD in CCS. METHODS: CCS were enrolled from the DCCSS-LATER cohort, consisting of 6,165 five-year CCS diagnosed between 1963 and 2002. Symptomatic VHD, defined as symptoms combined with a diagnostic test indicating VHD, was assessed from questionnaires and validated using medical records. Differences in the cumulative incidence of VHD between CCS who received treatments affecting splenic function and CCS who did not were assessed using the Gray test. Risk factors were analyzed in a multivariable Cox proportional hazards model. RESULTS: The study population consisted of 5,286 CCS, with a median follow-up of 22 years (5-50 years), of whom 59 (1.1%) had a splenectomy and 489 (9.2%) radiotherapy involving the spleen. VHD was present in 21 CCS (0.4%). The cumulative incidence of VHD at the age of 40 years was significantly higher in CCS who received treatments affecting splenic function (2.7%, 95% confidence interval (CI) 0.4%-4.9%) compared with CCS without (0.4%, 95% CI 0.1%-0.7%) (Gray's test, p = 0.003). Splenectomy was significantly associated with VHD in a multivariable analysis (hazard ratio 8.6, 95% CI 3.1-24.1). CONCLUSIONS AND IMPLICATIONS: Splenectomy was associated with VHD. Future research is needed to determine if CCS who had a splenectomy as part of cancer treatment might benefit from screening for VHD.

One-Year Outcomes of Transseptal Mitral Valve-in-Valve in Intermediate Surgical Risk Patients.

BACKGROUND: Transcatheter mitral valve-in-valve replacement offers a less-invasive alternative for high-risk patients with bioprosthetic valve failure. Limited experience exists in intermediate-risk patients. We aim to evaluate 1-year outcomes of the PARTNER 3 mitral valve-in-valve study. METHODS: This prospective, single-arm, multicenter study enrolled symptomatic patients with a failing mitral bioprosthesis demonstrating greater than or equal to moderate stenosis and regurgitation and Society of Thoracic Surgeons score ≥3% and <8%. A balloon-expandable transcatheter heart valve (SAPIEN 3, Edwards Lifesciences) was used via a transeptal approach. The primary end point was the composite of all-cause mortality and stroke at 1 year. RESULTS: A total of 50 patients from 12 sites underwent mitral valve-in-valve from 2018 to 2021. The mean age was 70.1±9.7 years, mean Society of Thoracic Surgeons score was 4.1%±1.6%, and 54% were female. There were no primary end point events (mortality or stroke) through 1 year, and no left-ventricular outflow tract obstruction, endocarditis, or mitral valve reintervention was reported. Six patients (12%) required rehospitalization, including heart failure (n=2), minor procedural side effects (n=2), and valve thrombosis (n=2; both resolved with anticoagulation). An additional valve thrombosis was associated with no significant clinical sequelae. From baseline to 1 year, all subjects with available data had none/trace or mild (grade 1+) mitral regurgitation and the New York Heart Association class improved in 87.2% (41/47) of patients. CONCLUSIONS: Mitral valve-in-valve with a balloon-expandable valve via transseptal approach in intermediate-risk patients was associated with improved symptoms and quality of life, adequate transcatheter valve performance, and no mortality or stroke at 1-year follow-up.

Exercise Pulmonary Hypertension in Heart Valve Disease.

The optimal management of heart valve disease (HVD) is still debated and many studies are underway to identify the best time to refer patients for the most appropriate treatment strategy (either conservative, surgical or transcatheter interventions). Exercise pulmonary hypertension (PH) can be detected during exercise stress echocardiography (ESE) and has been demonstrated to have an important prognostic role in HVD, by predicting symptoms and mortality. This review article aims to provide an overview on the prognostic role of exercise PH in valvulopathies, and its possible role in the diagnostic-therapeutic algorithm for the management of HVD.

Long-Term Outcomes of Mechanical Versus Bioprosthetic Aortic Valve Replacement in Patients Aged Under 50 Years: Meta-Analysis of Reconstructed Time-to-Event Data.

To compare the long-term outcomes of mechanical versus bioprosthetic aortic valve replacement (AVR) in patients aged <50 years, we performed a study-level meta-analysis with reconstructed time-to-event data including studies published by December of 2023. The primary outcome was overall survival. Secondary outcomes included reoperation, major bleeding, and stroke. A total of 5 studies met our inclusion criteria, with a total of 4,245 patients (2,311 mechanical and 1,934 bioprosthetic). All studies were observational and the mean age of groups across the studies ranged from 38.2 to 43.0 years. The median follow-up time was 11.4 years (interquartile range 6.9 to 15.0). Bioprosthetic AVR was associated with reduced overall survival and higher risk of all-cause death (hazard ratio [HR] 1.170 95% confidence interval [CI] 1.002 to 1.364, p = 0.046), increased risk of reoperation over time (HR 2.581, 95% CI 2.102 to 3.168, p <0.001), decreased risk of major bleeding (HR 0.500, 95% CI 0.367 to 0.682, p <0.001), and decreased risk of stroke (HR 0.751, 95% C, 0.565 to 0.998, p = 0.049) compared with mechanical AVR in patients aged <50 years. In conclusion, for patients aged <50 years, bioprosthetic AVR is associated with increased mortality and risk of reoperation compared with mechanical valves. In contrast, mechanical AVR is associated with an increased risk of major bleeding events and stroke. These aspects should be carefully considered during the selection of valve type in this age group; however, we should keep in mind that the statistically significant differences in the risk of all-cause death and stroke might not be clinically relevant (because of marginal statistical significance).

Long-Term Outcomes of Tricuspid Valve Replacement With Mechanical Versus Tissue Valves: Meta-Analysis of Reconstructed Time-to-Event Data.

Tricuspid valve replacement (TVR) with mechanical versus tissue valves remains a controversial subject. To evaluate the long-term effects of types of valves on patient-relevant outcomes, we performed a systematic review with meta-analysis of reconstructed time-to-event data of studies published by March 15, 2024 (according to referred the Reporting Items for Systematic Reviews and Meta-analyses guidelines). A total of 21 studies met our eligibility criteria and included 7,166 patients (mechanical: 2,495 patients, 34.8%). Patients who underwent mechanical TVR had a lower risk of death than those who received a tissue valve (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.70 to 0.84, p <0.001). Mechanical TVR was associated with lifetime gain, as evidenced by the restricted mean survival time, which was 2.2 years longer in patients who underwent TVR with mechanical valves (12.4 vs 10.2 years, p <0.001). Our landmark analysis for reoperations revealed the following: from the time point 0 to 7 years, we found no difference in the risk of reoperation between mechanical and tissues valves (HR 0.98, 95% CI 0.60 to 1.61, p = 0.946); however, from the time point 7 years onward, we found that mechanical TVR had a lower risk of reoperation in the follow-up (HR 0.24, 95% CI 0.08 to 0.72, p = 0.001). The meta-regression analysis demonstrated a modulating effect of atrial fibrillation on the association between mechanical valves and mortality; the HRs for all-cause death tended to decrease in the presence of populations with a larger proportion of atrial fibrillation (p = 0.018). In conclusion, our results suggest that TVR with mechanical valves, whenever considered clinically reasonable and accepted by patients as an option, can offer a better long-term survival and lower risk of reoperation in the long run.

Unraveling the Mechanisms of Valvular Heart Disease to Identify Medical Therapy Targets: A Scientific Statement From the American Heart Association.

Valvular heart disease is a common cause of morbidity and mortality worldwide and has no effective medical therapy. Severe disease is managed with valve replacement procedures, which entail high health care-related costs and postprocedural morbidity and mortality. Robust ongoing research programs have elucidated many important molecular pathways contributing to primary valvular heart disease. However, there remain several key challenges inherent in translating research on valvular heart disease to viable molecular targets that can progress through the clinical trials pathway and effectively prevent or modify the course of these common conditions. In this scientific statement, we review the basic cellular structures of the human heart valves and discuss how these structures change in primary valvular heart disease. We focus on the most common primary valvular heart diseases, including calcific aortic stenosis, bicuspid aortic valves, mitral valve prolapse, and rheumatic heart disease, and outline the fundamental molecular discoveries contributing to each. We further outline potential therapeutic molecular targets for primary valvular heart disease and discuss key knowledge gaps that might serve as future research priorities.

Overcoming prosthesis-patient mismatch with transcatheter aortic valve replacement.

For decades, surgeons have recognized the risk of prosthesis-patient mismatch (PPM) when treating aortic stenosis (AS) with surgical aortic valve replacement (SAVR). The concept of PPM-or placing a valve that is too small for the cardiac output requirements of the patient-has been associated with worse patient outcomes, including increased risk of death. Transcatheter aortic valve replacement (TAVR) has become the standard treatment for most patients with severe symptomatic AS and is associated with improved hemodynamics and lower risks of PPM. Larger surgical valves, stentless, and sutureless technology, and surgical aortic annulus enlargement (AAE) have been employed to avoid severe PPM. However, especially in the small aortic annulus (SAA), TAVR may provide a benefit. Understanding who is at risk for PPM requires preplanning, and cardiac-gated computed tomography (CT) imaging is the standard of care when considering TAVR. It should be standard for all patients with AS. Once SAA is identified, the risk of PPM can be calculated, and an informed decision made on whether to proceed with SAVR or TAVR. In the current TAVR era, younger patients are treated with TAVR driven by patient preference, but with little long-term data to support the practice. Selecting the best valve for the patient is a multifactorial decision often nuanced by anatomical considerations, hemodynamic and durability expectations, and decisions regarding lifetime management that may include placing a second valve. Although PPM may be only one of the factors to consider, the association with elevated mean gradients and worse outcomes certainly makes TAVR a good solution for many patients.

Progression of valve heart disease in a cohort of patients undergoing renal replacement therapy / Progressão da doença cardíaca valvar em coorte de doentes em terapia renal substitutiva

Abstract Introduction: Cardiovascular disease is an important cause of death among patients with chronic kidney disease (CKD). Valve calcification is a predictor of cardiovascular mortality and coronary artery disease. Objective: To assess heart valve disease frequency, associated factors, and progression in CKD patients. Methods: We conducted a retrospective study on 291 CKD patients at Hospital das Clínicas de Pernambuco. Inclusion criteria were age ≥ 18 with CKD and valve disease, while those on conservative management or with missing data were excluded. Clinical and laboratory variables were compared, and patients were categorized by dialysis duration (<5 years; 5-10 years; >10 years). Statistical tests, including chi-square, Fisher's exact, ANOVA, and Kruskal-Wallis, were employed as needed. Simple and multivariate binary regression models were used to analyze valve disease associations with dialysis duration. Significance was defined as p < 0.05. Results: Mitral valve disease was present in 82.5% (240) of patients, followed by aortic valve disease (65.6%; 86). Over time, 106 (36.4%) patients developed valve disease. No significant association was found between aortic, pulmonary, mitral, or tricuspid valve disease and dialysis duration. Secondary hyperparathyroidism was the sole statistically significant factor for mitral valve disease in the regression model (OR 2.59 [95% CI: 1.09-6.18]; p = 0.031). Conclusion: CKD patients on renal replacement therapy exhibit a high frequency of valve disease, particularly mitral and aortic valve disease. However, no link was established between dialysis duration and valve disease occurrence or progression.

Resumo Introdução: Doenças cardiovasculares são uma causa significativa de morte em pacientes com Doença Renal Crônica (DRC).

Foram aplicados os testes Qui-quadrado, exato de Fisher, ANOVA, Kruskal-Wallis. Associação entre valvopatia e TTD foi avaliada por regressão binária. Significância foi definida como p < 0,05. Resultados: A valvopatia mitral foi encontrada em 82,5% (240) dos casos, seguida da aórtica (65,6%; 86). Houve progressão da doença valvar em 106 (36,4%) pacientes. Não houve associação entre valvopatias aórtica, pulmonar, mitral ou tricúspide e TTD. Hiperparatireoidismo secundário foi a única variável explicativa significativa na regressão para valvopatia mitral (OR 2,59 [IC95%: 1,09-6,18]; p = 0,031). Conclusão: Encontramos alta frequência de valvopatias, especialmente mitral e aórtica, aem pacientes com DRC. Não houve associação entre TTD e valvopatia.

Heart disease in pregnancy and risk of pre-eclampsia: a Swedish register-based study.

BACKGROUND AND AIMS: Pre-eclampsia complicates 3-5% of pregnancies worldwide and is associated with adverse outcomes for the mother and the offspring. Pre-eclampsia and heart failure have common risk factors, including hypertension, obesity and diabetes. It is not known whether heart failure increases the risk of pre-eclampsia. This study examines whether pregestational heart failure increases the risk of pre-eclampsia. METHODS: In a registry-based case-cohort study that included all pregnancies in Sweden (n=3 125 527) between 1990 and 2019, all pregnancies with pre-eclampsia (n=90 354) were identified and up to five control pregnancies (n=451 466) for each case were chosen, matched on the mother's birth year. Multiple logistic regression analysis was used to evaluate the impact of heart failure on the risk of pre-eclampsia, with adjustment for established risk factors and other cardiovascular diseases. RESULTS: Women with heart failure had no increased risk for pre-eclampsia, OR 1.02 (95% CI 0.69 to 1.50). Women with valvular heart disease had an increased OR of preterm pre-eclampsia, with an adjusted OR of 1.78 (95% CI 1.04 to 3.06). Hypertension and diabetes were independent risk factors for pre-eclampsia. Obesity, multifetal pregnancies, in vitro fertilisation, older age, Nordic origin and nulliparity were more common among women who developed pre-eclampsia compared with controls. CONCLUSION: Women with heart failure do not have an increased risk of pre-eclampsia. However, women with valvular heart disease prior to pregnancy have an increased risk of developing preterm pre-eclampsia independent of other known risk factors.

Impact of Elevated Gradients After Transcatheter Aortic Valve Implantation for Degenerated Surgical Aortic Valve Bioprostheses.

BACKGROUND: Elevated aortic valve gradients are common after transcatheter aortic valve implantation for degenerated surgical aortic valve replacement bioprostheses, but their clinical impact is uncertain. METHODS: A total of 12 122 patients who underwent transcatheter aortic valve implantation-in-surgical aortic valve replacement from November 2011 to December 2019 in the Society of Thoracic Surgery/American College of Cardiology Transvalvular Therapeutics Registry were included. The primary outcome was a composite of 1-year all-cause mortality, stroke, myocardial infarction, or valve reintervention. Secondary outcomes included 1-year all-cause mortality, readmission, and change from baseline 12-question self-administered Kansas City Cardiomyopathy Questionnaire-Overall Summary Score. Due to nonlinearity observed with restricted cubic splines analysis, a Cox regression analysis with aortic valve mean gradient modeled as a spline-continuous variable (with 20 mm Hg as a cutoff) was used to study the 1-year composite outcome and mortality. RESULTS: The composite outcome occurred most frequently in patients with aortic valve mean gradient ≥30 and <10 mm Hg, as compared with those with 10 to 20 and 20 to 30 mm Hg ranges (unadjusted rates, 13.9%, 12.1%, 7.5%, and 6.5%, respectively; P=0.002). When the mean aortic valve gradient was ≥20 mm Hg, higher gradients were associated with greater risk of the 1-year composite outcome (adjusted hazard ratio, 1.02 [1.02-1.03] per mm Hg; P<0.001) and 1-year mortality (adjusted hazard ratio, 1.02 [1.00-1.03] per mm Hg; P=0.007). Whereas when the mean aortic valve gradient was <20 mm Hg, higher gradients were not significantly associated with the composite outcome (adjusted hazard ratio, 0.99 [0.98-1.003] per mm Hg; P=0.12) but were associated with lower 1-year mortality (adjusted hazard ratio, 0.98 [0.97-0.99] per mm Hg; P=0.007). CONCLUSIONS: The relationship between postprocedural aortic valve mean gradient after transcatheter aortic valve implantation-in-surgical aortic valve replacement and clinical outcomes is complex and nonlinear, with relatively greater adverse events occurring at low and high gradient extremes. Further study of factors mediating the relationship between postprocedural gradients and clinical outcomes, including low-flow states, is necessary.

Moderate Aortic Valve Stenosis Is Associated With Increased Mortality Rate and Lifetime Loss: Systematic Review and Meta-Analysis of Reconstructed Time-to-Event Data of 409 680 Patients.

BACKGROUND: The mortality risk attributable to moderate aortic stenosis (AS) remains incompletely characterized and has historically been underestimated. We aim to evaluate the association between moderate AS and all-cause death, comparing it with no/mild AS (in a general referral population and in patients with heart failure with reduced ejection fraction). METHODS AND RESULTS: A systematic review and pooled meta-analysis of Kaplan-Meier-derived reconstructed time-to-event data of studies published by June 2023 was conducted to evaluate survival outcomes among patients with moderate AS in comparison with individuals with no/mild AS. Ten studies were included, encompassing a total of 409 680 patients (11 527 with moderate AS and 398 153 with no/mild AS). In the overall population, the 15-year overall survival rate was 23.3% (95% CI, 19.1%-28.3%) in patients with moderate AS and 58.9% (95% CI, 58.1%-59.7%) in patients with no/mild aortic stenosis (hazard ratio [HR], 2.55 [95% CI, 2.46-2.64]; P<0.001). In patients with heart failure with reduced ejection fraction, the 10-year overall survival rate was 15.5% (95% CI, 10.0%-24.0%) in patients with moderate AS and 37.3% (95% CI, 36.2%-38.5%) in patients with no/mild AS (HR, 1.83 [95% CI, 1.69-2.0]; P<0.001). In both populations (overall and heart failure with reduced ejection fraction), these differences correspond to significant lifetime loss associated with moderate AS during follow-up (4.4 years, P<0.001; and 1.9 years, P<0.001, respectively). A consistent pattern of elevated mortality rate associated with moderate AS in sensitivity analyses of matched studies was observed. CONCLUSIONS: Moderate AS was associated with higher risk of death and lifetime loss compared with patients with no/mild AS.

Endocarditis Infecciosa: una mirada desde la semiología, a propósito de un caso / Infectious Endocarditis: a View from Semiology, case report

Infective endocarditis (IE) is an infection of the inner lining of the heart, especially the heart valves, and carries high morbidity and mortality. It can manifest itself acutely or subacutely, the latter being more insidious. Diagnosis is challenging, especially in early stages, requiring high clinical suspicion using modified Duke criteria. Treatment involves antimicrobials and in certain cases cardiac surgery is essential. The clinical case presents a patient with a history of aortic valve replacement, who develops acute symptoms. Although the diagnosis of endocarditis is achieved, a por physical examination delays starting optimal treatment. Early diagnosis is crucial to avoid adverse outcomes. Post-hospital discharge follow-up is essential to identify possible long-term complications.

La endocarditis infecciosa es una infección del revestimiento interno del corazón, especialmente de las válvulas cardíacas, con alta morbimortalidad. Se manifiesta como aguda o subaguda, siendo esta última más insidiosa. El diagnóstico es desafiante, especialmente en etapas tempranas, requiriendo sospecha clínica en pacientes con fiebre, factores de riesgo cardiacos o no cardiacos y el uso de los criterios de Duke- International Society of Cardiovascular Infectious Diseases. El tratamiento implica antimicrobianos y en ciertos casos es imprescindible la cirugía cardiaca. Se presenta un caso clínico de un paciente con antecedentes de reemplazo valvular aórtico, que desarrolla síntomas agudos. Aunque se logra el diagnóstico de endocarditis, un examen físico poco exhaustivo causa retraso en el inicio del tratamiento óptimo. Un diagnóstico temprano es crucial para evitar resultados adversos. Es esencial la vigilancia estrecha post alta hospitalaria debido a complicaciones a largo plazo.

Sarcopenia and aortic valve disease.

Valvular heart disease, including calcific or degenerative aortic stenosis (AS), is increasingly prevalent among the older adult population. Over the last few decades, treatment of severe AS has been revolutionised following the development of transcatheter aortic valve replacement (TAVR). Despite improvements in outcomes, older adults with competing comorbidities and geriatric syndromes have suboptimal quality of life outcomes, highlighting the cumulative vulnerability that persists despite valve replacement. Sarcopenia, characterised by loss of muscle strength, mass and function, affects 21%-70% of older adults with AS. Sarcopenia is an independent predictor of short-term and long-term outcomes after TAVR and should be incorporated as a prognostic marker in preprocedural planning. Early diagnosis and treatment of sarcopenia may reduce morbidity and mortality and improve quality of life following TAVR. The adverse effects of sarcopenia can be mitigated through resistance training and optimisation of nutritional status. This is most efficacious when administered before sarcopenia has progressed to advanced stages. Management should be individualised based on the patient's wishes/preferences, care goals and physical capability. Exercise during the preoperative waiting period may be safe and effective in most patients with severe AS. However, future studies are needed to establish the benefits of prehabilitation in improving quality of life outcomes after TAVR procedures.

Transcatheter versus surgical aortic valve replacement for severe aortic valve stenosis: Meta-analysis with trial sequential analysis.

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.

Management and outcomes of pregnant women with cardiovascular diseases in a cardio-obstetric team.

BACKGROUND: Cardiovascular diseases (CVDs) are currently the leading cause of maternal death in Western countries. Although multidisciplinary cardio-obstetric teams are recommended to improve the management of pregnant women with CVD, data supporting this approach are scarce. AIMS: To describe the characteristics and outcomes of pregnant patients with CVD managed within the cardio-obstetric programme of a tertiary centre. METHODS: We included every pregnant patient with history of CVD managed by our cardio-obstetric team between June 2017 and December 2019, and collected all major cardiovascular events (death, heart failure, acute coronary syndromes, stroke, endocarditis and aortic dissection) that occurred during pregnancy, peripartum and the following year. RESULTS: We included 209 consecutive pregnancies in 202 patients. CVDs were predominantly valvular heart diseases (37.8%), rhythm disorders (26.8%), and adult congenital heart diseases (22.5%). Altogether, 47.4% were classified modified World Health Organization (mWHO)>II, 66.5% had CARdiac disease in PREGnancy score (CARPREG II)≥2 and 80 pregnancies (38.3%) were delivered by caesarean section. Major cardiovascular events occurred in 16 pregnancies (7.7%, 95% confidence interval [CI] 4.5-12.2) during pregnancy and in three others (1.5%, 95% CI 0.3-4.1) during 1-year follow-up. Most events (63.1%) occurred in the 16.3% of patients with unknown CVD before pregnancy. CONCLUSIONS: The management of pregnant patients with CVD within a cardio-obstetric team seems encouraging as we found a relatively low rate of cardiovascular events compared to the high-risk profile of our population. However, most of the remaining events occurred in patients without cardiac monitoring before pregnancy.

Preconception counselling in women of reproductive age attending cardiology clinics in Scotland.

BACKGROUND: Guidelines for the management of cardiovascular disease (CVD) recommend preconception risk stratification and counselling in all women of childbearing age. We assessed the provision of preconception counselling (PCC) among women of reproductive age attending general cardiology outpatient clinics over a 12-month period in two large health boards in Scotland. METHODS AND RESULTS: Electronic health records were reviewed and data on patient demographics, cardiac diagnoses, medication use and the content of documented discussions regarding PCC were recorded. Women were classified according to the modified WHO (mWHO) risk stratification system. Among 1650 women with a cardiac diagnosis included (1 January 2016-31 December 2016), the mean age was 32.7±8.6 years, and 1574 (95.4%) attended a consultant-led clinic. A quarter (402, 24.4%) were prescribed at least one potentially fetotoxic cardiovascular medication. PCC was documented in 10.3% of women who were not pregnant or were unable to conceive at the time of review (159/1548). The distribution of mWHO classification, and proportion of patients within each mWHO category who received any form of PCC, was 15.0% and 6.0% in mWHO class I, 20.2% and 8.7% in mWHO class II, 22.6% and 10.6% in mWHO class II-III, 9.5% and 15.7% in mWHO class III and 3.9% and 19.7% in mWHO class IV. CONCLUSION: PCC is documented infrequently in women of reproductive age with CVD in the general outpatient setting. Education relating to the risks of cardiac disease in pregnancy for clinicians and patients, and tools to support healthcare providers in delivering PCC, is important.

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.
