RESUMO

BACKGROUND: Trans-carotid Transcatheter Aortic Valve Replacement (TC-TAVR) has emerged as an alternative TAVR access. However, scarce data on long-term outcomes following TC-TAVR exist. This study aimed to evaluate 5-year clinical outcomes post-TC-TAVR. METHODS: One hundred ten consecutive patients who underwent TC-TAVR and completed the 5-year after the procedure were included. Baseline, procedural, and follow-up data were collected prospectively in a dedicated database. The primary endpoint was the incidence of a composite of all-cause mortality, stroke, and repeat hospitalization. Echocardiography results, New York Heart Association (NYHA) class, and quality of life (QOL) assessed with the EuroQol visual analogue scale (EQ-VAS) were examined over the 5-year follow-up. RESULTS: The median age was 77 (72-82.2) years, 42.3% were women, and the median STS risk score was 5.02% (3.4-7.5%). The incidence of the composite endpoint was 54.5%. Death from any cause occurred in 45.6% of cases (11.9 per 100 patients-years), stroke in 8.2% (1.9 per 100 patient-years), disabling stroke in 2.7% (0.7 per 100 patient-years), and rehospitalization in 27.2%. The improvements in valve hemodynamics, NYHA class, and EQ-VAS following the procedure persisted at the 5-year follow-up (p<.001). Bioprosthetic valve failure occurred in 0.9%. CONCLUSIONS: About half of the moderate-to-high-risk patients undergoing TC-TAVR survived with no major cardiovascular events at 5-year follow-up. The yearly incidence of strokes was low, and early improvements in valve hemodynamics, functional status and QOL persisted at 5 years. These results suggest the long-term safety and efficacy of TC-TAVR, and would support this approach as an alternative to surgery in non-transfemoral candidates.

RESUMO

AIMS: In low-risk patients with severe aortic stenosis (AS), sutureless surgical aortic valve replacement (SU-SAVR) may be an alternative to transcatheter aortic valve implantation (TAVI). The risk of heart failure hospitalization (HFH) after aortic valve replacement (AVR) in this population is incompletely characterized. This study aims to investigate the incidence, predictors, and outcomes of HFH in patients undergoing SU-SAVR versus TAVI. METHODS AND RESULTS: Patients referred for AVR between 2013 and 2020 at two centres were consecutively included. The decision for SU-SAVR or TAVI was determined by a multidisciplinary Heart Team. Cox regression and competing risk analysis were conducted to assess adverse events. Of 594 patients (mean age 77.5 ± 6.4, 59.8% male), 424 underwent SU-SAVR, while 170 underwent TAVI. Following a mean follow-up of 34.1 ± 23.1 months, HFH occurred in 112 (27.8%) SU-SAVR patients and in 8 (4.8%) TAVI patients (P < 0.001). The SU-SAVR cohort exhibited higher all-cause mortality (138 [32.5%] patients compared with 30 [17.6%] in the TAVI cohort [P < 0.001]). These differences remained significant after sensitivity analyses with 1:1 propensity score matching for baseline variables. SU-SAVR with HFH was associated with increased all-cause mortality (61.6% vs. 23.1%, P < 0.001). Independent associates of HFH in SU-SAVR patients included diabetes, atrial fibrillation, chronic obstructive pulmonary disease, lower glomerular filtration rate and lower left ventricular ejection fraction. SU-SAVR patients with HFH had a 12-month LVEF of 59.4 ± 12.7. CONCLUSIONS: In low-risk AS, SU-SAVR is associated with a higher risk of HFH and all-cause mortality compared to TAVI. In patients with severe AS candidate to SU-SAVR or TAVI, TAVI may be the preferred intervention.

RESUMO

BACKGROUND: Angiotensin receptor blockers (ARBs) may slow down the progression of aortic stenosis (AS) through their antifibrotic effect. Women present more valvular fibrosis than men, so ARBs may have more effect in females. Our aim was to assess the impact of ARBs on the remodelling of the aortic valve in men and women. METHODS: We included patients who had an aortic valve replacement with or without coronary bypass grafting from 2006 to 2013. Patients with missing echocardiographic or histologic data were excluded. Warren-Yong and fibrosis scores of the explanted valves were performed. Patients were divided into 4 phenotypes according to their Warren-Yong and fibrosis scores: mild calcification/fibrosis, severe calcification/fibrosis group, predominant fibrosis group, predominant calcification group. RESULTS: Among the 1321 included patients, the vast majority (89%) has severe AS. Patients in the predominant fibrosis group, compared with the predominant calcium group, were more often female (39% vs 31%; P = 0.008) with bicuspid valves (44% vs 34%; P = 0.002), and less often used ARBs (25% vs 30%; P = 0.046). Female sex was independently associated with being in the predominant fibrosis group (odds ratio 1.45, 95% confidence interval 1.08-1.95; P = 0.01), with a significant interaction between female sex and ARBs. Women taking ARBs compared with women not taking ARBs had significantly lower fibrosis scores (P < 0.001). This difference was not seen in men. CONCLUSIONS: In this large series of patients with moderate-severe AS, among the women there was a negative association between intake of ARBs and valvular fibrosis. Thus, the possible effects of ARBs may be sex specific, with a larger therapeutic role in women.

RESUMO

BACKGROUND: The optimal treatment in patients with severe aortic stenosis and small aortic annulus (SAA) remains to be determined. This study aimed to compare the hemodynamic and clinical outcomes between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in patients with a SAA. METHODS: This prospective multicenter international randomized trial was performed in 15 university hospitals. Participants were 151 patients with severe aortic stenosis and SAA (mean diameter <23 mm) randomized (1:1) to TAVR (n=77) versus SAVR (n=74). The primary outcome was impaired valve hemodynamics (ie, severe prosthesis patient mismatch or moderate-severe aortic regurgitation) at 60 days as evaluated by Doppler echocardiography and analyzed in a central echocardiography core laboratory. Clinical events were secondary outcomes. RESULTS: The mean age of the participants was 75.5±5.1 years, with 140 (93%) women, a median Society of Thoracic Surgeons predicted risk of mortality of 2.50% (interquartile range, 1.67%-3.28%), and a median annulus diameter of 21.1 mm (interquartile range, 20.4-22.0 mm). There were no differences between groups in the rate of severe prosthesis patient mismatch (TAVR, 4 [5.6%]; SAVR, 7 [10.3%]; P=0.30) and moderate-severe aortic regurgitation (none in both groups). No differences were found between groups in mortality rate (TAVR, 1 [1.3%]; SAVR, 1 [1.4%]; P=1.00) and stroke (TAVR, 0; SAVR, 2 [2.7%]; P=0.24) at 30 days. After a median follow-up of 2 (interquartile range, 1-4) years, there were no differences between groups in mortality rate (TAVR, 7 [9.1%]; SAVR, 6 [8.1%]; P=0.89), stroke (TAVR, 3 [3.9%]; SAVR, 3 [4.1%]; P=0.95), and cardiac hospitalization (TAVR, 15 [19.5%]; SAVR, 15 [20.3%]; P=0.80). CONCLUSIONS: In patients with severe aortic stenosis and SAA (women in the majority), there was no evidence of superiority of contemporary TAVR versus SAVR in valve hemodynamic results. After a median follow-up of 2 years, there were no differences in clinical outcomes between groups. These findings suggest that the 2 therapies represent a valid alternative for treating patients with severe aortic stenosis and SAA, and treatment selection should likely be individualized according to baseline characteristics, additional anatomical risk factors, and patient preference. However, the results of this study should be interpreted with caution because of the limited sample size leading to an underpowered study, and need to be confirmed in future larger studies.

RESUMO

Introducción y objetivos: Evaluar la prevalencia, las características clínicas y el impacto de la angina en pacientes con estenosis aórtica sometidos a implante percutáneo de válvula aórtica (TAVI). Métodos: Se analizó a 1.687 pacientes consecutivos con estenosis aórtica sometidos a TAVI, clasificados en función de la presencia o ausencia basal de angina. Los datos basales, del procedimiento y del seguimiento se recogieron en una base de datos local. Resultados: Un total de 497 pacientes (29%) presentaban angina antes del TAVI. Los pacientes con angina basal presentaban peor clase funcional (NYHA> II, el 69% frente al 63%; p=0,017) y una mayor prevalencia de enfermedad coronaria (el 74% frente al 56%; p <0,001). La angina basal no mostró impacto pronóstico a 1 año en mortalidad por cualquier causa (HR=1,02; IC95%, 0,71-1,48; p=0,898) ni en mortalidad cardiovascular (HR=1,2; IC95%, 0,69-2,11; p=0,517). Sin embargo, la persistencia de angina 30 días después del procedimiento se asoció con un incremento en la mortalidad a 1 año, tanto total (HR=4,86; IC95%, 1,71-13,8; p=0,003) como de causa cardiovascular (HR=20,7; IC95%, 3,50-122,6; p=0,001). Conclusiones: Más de un cuarto de los pacientes con estenosis aórtica sometidos a TAVI tenían angina antes del procedimiento. La angina basal no mostró impacto pronóstico alguno. Sin embargo, la persistencia de angina 30 días después del procedimiento se asoció con una mayor mortalidad al año.(AU)


Introduction and objectives: To evaluate the prevalence, clinical characteristics, and outcomes of patients with angina undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Methods: A total of 1687 consecutive patients with severe aortic stenosis undergoing TAVR at our center were included and classified according to patient-reported angina symptoms prior to the TAVR procedure. Baseline, procedural and follow-up data were collected in a dedicated database. Results: A total of 497 patients (29%) had angina prior to the TAVR procedure. Patients with angina at baseline showed a worse New York Heart Association (NYHA) functional class (NYHA class> II: 69% vs 63%; P=.017), a higher rate of coronary artery disease (74% vs 56%; P <.001), and a lower rate of complete revascularization (70% vs 79%; P <.001). Angina at baseline had no impact on all-cause mortality (HR, 1.02; 95%CI, 0.71-1.48; P=.898) and cardiovascular mortality (HR, 1.2; 95%CI, 0.69-2.11; P=.517) at 1 year. However, persistent angina at 30 days post-TAVR was associated with increased all-cause mortality (HR, 4.86; 95%CI, 1.71-13.8; P=.003) and cardiovascular mortality (HR, 20.7; 95%CI, 3.50-122.6; P=.001) at 1-year follow-up. Conclusions: More than one-fourth of patients with severe aortic stenosis undergoing TAVR had angina prior to the procedure. Angina at baseline did not appear to be a sign of a more advanced valvular disease and had no prognostic impact; however, persistent angina at 30 days post-TAVR was associated with worse clinical outcomes.(AU)

RESUMO

Background: Clinical outcomes and quality of life (QoL) indices are not well described after transcatheter aortic valve replacement (TAVR) in patients aged ≥ 90 years. Methods: We conducted a retrospective cohort study of TAVR among nonagenarian patients between 2008 and 2020. The survival of TAVR patients among nonagenarians was compared to the provincial estimated survival for an age- and sex-matched general population. QoL was assessed up to 1 year postintervention, using standardized questionnaires. Results: During the study period, n = 268 patients aged ≥ 90 years were evaluated for severe aortic stenosis. TAVR was performed in n = 171 (48% female; median [IQR] Rockwood Clinical Frailty Scale score: 4 [3-4]); n = 84 underwent medical therapy; and n = 13 underwent surgical aortic valve replacement. Survival was significantly better following TAVR, compared to that after MT (adjusted hazard ratio [95% CI]: 1.99 [1.37-2.88], P < 0.001). TAVR patients demonstrated a survival advantage compared with the general population, with an estimated relative mortality of 0.86 (0.75-0.87). TAVR patients showed sustained improvements in functional status and QoL up to 1 year compared to baseline (all P < 0.05): the 6-minute walk test results improved from 192 to 252 m; the Kansas City Cardiomyopathy Questionnaire score improved from 64 to 81; the Duke Activity Status Index score improved from 13 to 16; and the health state scale result of the Euro Quality of life - 5 Dimensions improved from 63% to 74%. Conclusions: Nonagenarians undergoing TAVR experience a slightly better survival rate, compared to that of an age- and sex-matched general population, and they have significant improvements in functional status and several QoL indices following the procedure.


Introduction: Les résultats cliniques et les indices de la qualité de vie (QdV) après le remplacement valvulaire aortique par cathéter (RVAC) chez les patients ≥ 90 ans ne sont pas bien décrits. Méthodes: Nous avons réalisé une étude de cohorte rétrospective sur le RVAC chez les patients nonagénaires entre 2008 et 2020. Nous avons comparé la survie des patients nonagénaires qui avaient subi un RVAC à la survie provinciale estimée d'une population générale appariée selon l'âge et le sexe. Nous avons évalué la QdV jusqu'à 1 an après l'intervention au moyen de questionnaires standardisés. Résultats: Durant la période étudiée, nous avons inclus des patients (n =268) âgés de ≥ 90 ans et évalués pour une sténose aortique sévère. Le RVAC a été réalisé chez 171 patients (48 % de sexe féminin ; score médian [écart interquartile] à l'échelle de fragilité clinique de Rockwood [Rockwood Clinical Frailty Scale] : 4 [3-4]) ; 84 ont reçu un traitement médical (TM) ; 13 ont subi un remplacement valvulaire aortique chirurgical. La survie était significativement meilleure à la suite du RVAC, comparativement à celle des patients TM (rapport de risque ajusté [IC à 95 %] : 1,99 [1,37-2,88], P < 0,001). Par rapport à la population générale, les patients ayant subi un RVAC ont démontré un avantage sur le plan de la survie, soit une mortalité relative estimée de 0,86 (0,75-0,87). Les patients ayant subi un RVAC ont montré des améliorations continues de l'état fonctionnel et de la QdV jusqu'à 1 an par rapport au début (toutes les valeurs P < 0,05) : les résultats à l'épreuve de marche de 6 minutes sont passés de 192 à 252 m ; les scores au questionnaire Kansas City Cardiomyopathy Questionnaire (KCCQ) sont passés de 64 à 81 ; les scores au questionnaire Duke Activity Status Index (DASI) sont passés de 13 à 16 ; les résultats à l'échelle de l'état de santé de l'EQ-5D (de l'EuroQol Group) sont passés de 63 % à 74 %. Conclusions: Les nonagénaires qui subissent un RVAC ont un taux de survie légèrement meilleur à celui d'une population générale appariée selon l'âge et le sexe, et montrent des améliorations significatives de leur état fonctionnel et de plusieurs indices de la QdV à la suite de l'intervention.

RESUMO

INTRODUCTION: Small aortic annulus (SAA) poses a challenge in the management of patients with severe aortic stenosis requiring aortic valve replacement - both surgical and transcatheter - since it has been associated with worse clinical outcomes. AREAS COVERED: This review aims to comprehensively summarize the available evidence regarding the management of aortic stenosis in patients with SAA and discuss the current controversies as well as future perspectives in this field. EXPERT OPINION: It is paramount to agree in a common definition for diagnosing and properly treating SAA patients, and for that purpose, multidetector computer tomography is essential. The results of recent trials led to the expansion of transcatheter aortic valve replacement among patients of all the surgical-risk spectrum, and the choice of treatment (transcatheter, surgical) should be based on patient comorbidities, anatomical characteristics, and patient preferences.

RESUMO

BACKGROUND: The updated Valve Academic Research Consortium (VARC) definition for bleeding events after transcatheter aortic valve replacement (TAVR) lacks of clinical validation. OBJECTIVES: The aim of this study was to determine the incidence, predictors, and clinical impact of bleeding events following TAVR as defined by recent VARC-3 criteria. METHODS: A total of 2,384 consecutive patients with severe symptomatic aortic stenosis undergoing TAVR were included. Early (at index hospitalization) and late (after hospital discharge) bleeding complications were defined according to VARC-3 criteria as type 1, 2, 3, or 4. Baseline, procedural, and follow-up (24 [IQR: 12-43] months) data were prospectively collected. RESULTS: Bleeding events occurred in 761 patients (31.9%): types 1, 2, 3, and 4 in 169 (22.2%), 399 (52.4%), 149 (19.6%), and 44 (5.8%) patients, respectively. The primary vascular access site and gastrointestinal locations were the most common bleeding sources among early and late bleeding events, respectively. Female sex, thoracotomy access, larger (14-F) sheath use, and dual antiplatelet therapy determined an increased risk of early bleeding events (P < 0.02 for all). The use of the radial artery for secondary access was associated with a significant risk reduction of early bleeding (P < 0.001). Type 2 and type 3 events were associated with an increased mortality risk at 30-day (HR: 2.94 [95% CI: 1.43-6.03; P = 0.003] and HR: 4.91 [95% CI: 2.19-11.03; P < 0.001], respectively) and 1-year (HR: 1.86 [95% CI: 1.28-2.69; P = 0.001] and HR: 2.28 [95% CI: 1.41-3.66; P = 0.001], respectively) follow-up. A similar prognostic pattern was observed when applying VARC-2 criteria but with a much lower global incidence of early bleeding events (19% vs 27%; P < 0.001). CONCLUSIONS: Bleeding events after TAVR were associated with poorer short- and long-term survival. The magnitude of this correlation was proportional to bleeding severity defined according to VARC-3 criteria. Further studies on bleeding prevention following TAVR are warranted to improve procedural safety and patient prognosis.

RESUMO

Background: The long-term outcomes of patients undergoing functional assessment of coronary lesions with fractional flow reserve (FFR) while awaiting transcatheter aortic valve implantation (TAVI) are unknown. Data on the safety of intracoronary adenosine use in this setting are scarce. The objectives of this study were to describe (1) the long-term outcomes based on the coronary artery disease (CAD) assessment strategy used and (2) the safety of intracoronary adenosine in patients with severe aortic stenosis (AS). Methods: 1023 patients with severe AS awaiting TAVI were included. Patients were classified according to their CAD assessment strategy: angiography guided or FFR guided. Patients were further subdivided according to the decision to proceed with percutaneous coronary intervention (PCI): angiography-guided PCI (375/1023), angiography-guided no-PCI (549/1023), FFR-guided PCI (50/1023), and FFR-guided no-PCI (49/1023). Patients were followed up for the occurrence of major adverse cardiac and cerebrovascular events (MACCEs). Results: At a mean follow-up of 33.7 months, we observed no significant differences in terms of major adverse cardiovascular and cerebrovascular events (MACCE) in the angiography-guided group (42.4%) compared with the FFR-guided group (37.4%) (p = 0.333). When comparing outcomes of the FFR-guided no-PCI group (32.7%) with the angiography-guided PCI group (46.4%), no significant difference was noted (p = 0.999). Following intracoronary adenosine, a single adverse event occurred. Conclusions: In this population, intracoronary adenosine is safe and well tolerated. We found no significant benefit to an FFR-guided strategy compared with an angiography-guided strategy with respect to MACCEs. Although clinically compelling, avoiding the procedural risks of PCI by deferring the intervention in functionally insignificant lesions failed to show a statistically significant benefit.

RESUMO

Introduction: Glass coverslips are used as a substrate since Harrison's initial nerve cell culture experiments in 1910. In 1974, the first study of brain cells seeded onto polylysine (PL) coated substrate was published. Usually, neurons adhere quickly to PL coating. However, maintaining cortical neurons in culture on PL coating for a prolonged time is challenging. Methods: A collaborative study between chemical engineers and neurobiologists was conducted to find a simple method to enhance neuronal maturation on poly-D-lysine (PDL). In this work, a simple protocol to coat PDL efficiently on coverslips is presented, characterized, and compared to a conventional adsorption method. We studied the adhesion and maturation of primary cortical neurons with various morphological and functional approaches, including phase contrast microscopy, immunocytochemistry, scanning electron microscopy, patch clamp recordings, and calcium imaging. Results: We observed that several parameters of neuronal maturation are influenced by the substrate: neurons develop more dense and extended networks and synaptic activity is enhanced, when seeded on covalently bound PDL compared to adsorbed PDL. Discussion: Hence, we established reproducible and optimal conditions enhancing maturation of primary cortical neurons in vitro. Our method allows higher reliability and yield of results and could also be profitable for laboratories using PL with other cell types.

RESUMO

The use of transcatheter edge-to-edge mitral valve repair (TEER) in symptomatic patients with severe mitral regurgitation (MR) has dramatically increased over the last few years. Current guidelines consider TEER as a reasonable option in symptomatic patients with primary or chronic secondary severe MR with high or prohibitive surgical risk and favorable anatomy. However, several anatomical and morphological mitral features have restricted the use of this mini-invasive technique in its early experience. The latest fourth generation (G4) of the MitraClip system has been recently introduced and includes the possibility of independent leaflet grasping and 4 different sizes. This technical update offers the possibility of selecting and combining multiple devices for complex mitral valve anatomies and challenging procedures, which helps expand the applications of TEER. The present review describes the potential advantages and the help of the MitraClip G4 devices to overcome various anatomic and morphologic issues in challenging cases with complex primary and secondary MR procedures.

RESUMO

BACKGROUND: The Valve Academic Research Consortium (VARC)-3 definition for myocardial injury after transcatheter aortic valve replacement (TAVR) lacks of clinical validation. OBJECTIVES: This study sought to determine the incidence, predictors, and clinical impact of periprocedural myocardial injury (PPMI) following TAVR as defined by recent VARC-3 criteria. METHODS: We included 1,394 consecutive patients who underwent TAVR with a new-generation transcatheter heart valve. High-sensitivity troponin levels were assessed at baseline and within 24 hours after the procedure. PPMI was defined according to VARC-3 criteria as an increase ≥70 times in troponin levels (vs ≥15 times according to the VARC-2 definition). Baseline, procedural, and follow-up data were prospectively collected. RESULTS: PPMI was diagnosed in 193 (14.0%) patients. Female sex and peripheral artery disease were independent predictors of PPMI (P < 0.01 for both). PPMI was associated with a higher risk of mortality at 30-day (HR: 2.69, 95% CI: 1.50-4.82; P = 0.001) and 1-year (for all-cause mortality, HR: 1.54; 95% CI: 1.04-2.27; P = 0.032; for cardiovascular mortality, HR: 3.04; 95% CI: 1.68-5.50; P < 0.001) follow-up. PPMI according to VARC-2 criteria had no impact on mortality. CONCLUSIONS: About 1 out of 10 patients undergoing TAVR in the contemporary era had PPMI as defined by recent VARC-3 criteria, and baseline factors like female sex and peripheral artery disease determined an increased risk. PPMI had a negative impact on early and late survival. Further studies on the prevention of PPMI post-TAVR and implementing measures to improve outcomes in PPMI patients are warranted.

RESUMO

INTRODUCTION: Superior vena cava (SVC) tear is the most lethal complication during transvenous lead extraction (TLE) with a mortality rate as high as 50%. Treatment involves aggressive attempts to maintain cardiac output and immediate sternotomy to localize and repair the vascular tear. Occlusion balloons have been developed to provisionally occlude the lacerated SVC and to provide hemodynamic stability allowing time for surgery. In case of mediastinal hematoma without hemodynamic instability, the strategy remains unclear. METHODS AND RESULTS: We describe two cases of SVC tear during TLE. The first case was a 60-year-old man who presented with a right ventricular single-chamber defibrillator lead fracture and innominate vein stenosis. The RV lead was removed using a laser sheath causing a mediastinal hematoma with no active bleeding during surgical exploration few hours later. The second case was a 28-year-old man that presented with a right atrial (RA) lead fracture and RV lead insulation failure in a dual-chamber defibrillator (ICD). CONCLUSION: Both the RA and RV leads were removed with mechanical sheaths, and a mediastinal hematoma was medically managed.

RESUMO

INTRODUCTION AND OBJECTIVES: To evaluate the prevalence, clinical characteristics, and outcomes of patients with angina undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. METHODS: A total of 1687 consecutive patients with severe aortic stenosis undergoing TAVR at our center were included and classified according to patient-reported angina symptoms prior to the TAVR procedure. Baseline, procedural and follow-up data were collected in a dedicated database. RESULTS: A total of 497 patients (29%) had angina prior to the TAVR procedure. Patients with angina at baseline showed a worse New York Heart Association (NYHA) functional class (NYHA class> II: 69% vs 63%; P=.017), a higher rate of coronary artery disease (74% vs 56%; P <.001), and a lower rate of complete revascularization (70% vs 79%; P <.001). Angina at baseline had no impact on all-cause mortality (HR, 1.02; 95%CI, 0.71-1.48; P=.898) and cardiovascular mortality (HR, 1.2; 95%CI, 0.69-2.11; P=.517) at 1 year. However, persistent angina at 30 days post-TAVR was associated with increased all-cause mortality (HR, 4.86; 95%CI, 1.71-13.8; P=.003) and cardiovascular mortality (HR, 20.7; 95%CI, 3.50-122.6; P=.001) at 1-year follow-up. CONCLUSIONS: More than one-fourth of patients with severe aortic stenosis undergoing TAVR had angina prior to the procedure. Angina at baseline did not appear to be a sign of a more advanced valvular disease and had no prognostic impact; however, persistent angina at 30 days post-TAVR was associated with worse clinical outcomes.

RESUMO

Background: Treating disordered feeding at a young age reduces risks of future feeding problems, but not all children profit equally; can we define predictors of a worse prognosis? Objectives: In 252 children, with a mean age of 4; 7 years (SD = 3 years; range 5 months to 17; 10 years), who had undergone behavioral day treatment in the past, several variables were investigated, retrieved from initial consultation (t1) and re-assessed at follow-up (t2). Method: Logistic regressions were carried out with sex, gastro-intestinal problems, refusal of the first nutrition, syndrome/intellectual disability, Down's syndrome, autism spectrum disorder, comorbidity of medical diseases (other than gastro-intestinal problems), restrictive caloric food intake and selective food intake, as the predictor variables from t1, and age-appropriate food intake at t2 as the dependent variable. The potential role of sensory processing problems was reviewed at t2. Results: About 73% had improved towards an age-appropriate food intake. Sex (boys), syndrome/intellectual disability, and a lack of varied nutritional intake at t1 were predictors of a worse prognosis. We found a small, but significant correlation between current selective eating patterns and general sensory processing problems. Conclusion: Feeding disordered children, especially boys, with intellectual disabilities or selective eating patterns are at risk for not achieving an age-adequate food intake at a later age, despite behavioral treatment.

RESUMO

BACKGROUND: No data exist on the clinical and prognostic significance of syncope in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. METHODS: A total of 1705 consecutive patients with severe aortic stenosis undergoing TAVR in a tertiary university centre between 2007 and 2021 were included and classified according to the presence of syncope before the TAVR procedure. Baseline, procedural, and follow-up data were collected prospectively in a dedicated database. RESULTS: A total of 115 patients (7%) presented with syncope before the TAVR procedure. Of these, 15 patients (13%) showed arrhythmic episodes as the probable cause of the syncope, and all of them had pacemakers implanted at a median of 13 (6 to 53) days before the TAVR procedure. Patients with syncope were older (82 ± 8 years vs 80 ± 8 years, P = 0.001) and had a higher rate of pacemaker implantation before the TAVR procedure (27% vs 14%, P < 0.001), with no differences between groups regarding the severity of aortic stenosis (transvalvular gradient, valve area). There were no differences between groups in 30-day (adjusted hazard ratio [HR], 1.28; 95% confidence interval [CI], 0.46-3.60) and 1-year (adjusted HR, 0.71; 95% CI, 0.0.35-1.45) mortality following TAVR. CONCLUSIONS: Syncope was not associated with a more advanced valvular disease and had no significant prognostic impact on patients undergoing TAVR. However, arrhythmias and conduction-system disturbances were more common in patients with previous syncope and might play a relevant role in the pathogenesis of syncope in patients with aortic stenosis.

RESUMO

OBJECTIVES: The effectiveness of a multidisciplinary heart team in the management of patients with severe symptomatic aortic stenosis is unknown. This study evaluated the impact of a heart team on the outcomes of surgical aortic valve replacement in octogenarians. METHODS: Between May 2007 and January 2016, 528 patients aged 80 years or more were referred to our institutional heart team for a transcatheter aortic valve replacement. Among these, 101 were redirected to surgical aortic valve replacement (heart team group). These patients were compared with a surgical aortic valve replacement cohort (n = 506) without prior heart team screening (non-heart team group), taken from the same time period. Propensity score matching with bootstrap analysis was performed; 76 heart team patients were matched to 76 non-heart team patients. Early and late outcomes including survival and readmission for cardiovascular causes were compared. RESULTS: Matched subgroups were largely comparable; congestive heart failure and echocardiographic pulmonary hypertension were more prevalent in the heart team group. In-hospital mortality was significantly lower in the matched heart team group (0% vs 6.0%, bootstrap mean difference 6.0%, 95% confidence interval, 2.2-9.8). The risk of stroke, low cardiac output state, reexploration for bleeding, pneumonia, and prolonged ventilation was also significantly lower in the heart team group. There was no significant between-group difference regarding late survival (hazard ratio, 0.86, 95% confidence interval, 0.55-1.33, P = .49) or readmission for cardiovascular reasons (hazard ratio, 0.70, 95% confidence interval, 0.41-1.20, P = .19). CONCLUSIONS: Preoperative multidisciplinary assessment of octogenarians by a heart team was associated with lower in-hospital mortality and adverse events after surgical aortic valve replacement.

RESUMO

Aortic pseudoaneurysms after acute Type A aortic dissection (ATAAD) repair have been reported as high as 10-24% and surgical treatment is usually recommended. The objective of this article is to examine the safety and efficacy of a conservative approach to aortic pseudoaneurysm and to compare this approach to standard surgical treatment. We retrospectively examined 39 patients who had an aortic pseudoaneurysm after ATAAD surgery in order to examine outcomes (baseline characteristics, presentation and freedom from aortic events and mortality). We initially identified 31 patients treated conservatively (CT). After close follow up, 5 of them were operated so 13 patients were treated surgically (ST) and analyzed at a long-term follow-up while 26 were in the conservative group. Mean follow- - up of the whole cohort was 7.9 ± 5.9 years. The freedom from aortic-related mortality at 1, 5, and 10 years was 100%, 83.3% and 72.9% for the ST group and 95.8%, 77.3%, and 77.3% for the CT group (P = 0.35). A conservative approach to aortic pseudoaneurysms could be justified in asymptomatic patients. A close follow-up by a dedicated aortic clinic is mandatory so that patients are referred for surgery when necessary.
