RESUMO
INTRODUCTION: Pulsed-field ablation (PFA) is a novel nonthermal energy that shows unique features that can be of use beyond pulmonary vein ablation, like tissue selectivity or proximity rather than contact dependency. METHODS AND RESULTS: We report three cases of right focal atrial tachycardias arising from the superior cavoatrial junction and the crista terminalis, in close relationship with the phrenic nerve, effectively ablated using a commercially available PFA catheter designed for pulmonary vein isolation without collateral damage. CONCLUSION: PFA can be useful for treating right atrial tachycardias involving sites near the phrenic nerve, avoiding the need for complex nerve-sparing strategies.
RESUMO
BACKGROUND: Transcatheter aortic valve implantation (TAVI) is increasingly being used in younger patients and those with lower peri-procedural risk, meaning more patients will live long enough to experience structural valve deterioration (SVD) of the bioprosthesis, indicating repeated TAVI. Experience of repeated TAVI-transcatheter heart valve (THV) implantation into an index THV is limited. This registry aims to assess the peri-procedural and short-term safety, efficacy and durability of repeated TAVI. METHODS: The ReTAVI Prospective observational registry is an investigator-initiated, multicentre, international, prospective registry of patients undergoing repeated TAVI using balloon-expandable SAPIEN prosthesis to evaluate procedural and short-term safety, efficacy and durability as well as anatomical and procedural factors associated with optimal results. The registry will enrol at least 150 patients across 60 high-volume centres. Patients must be ≥18 years old, have had procedural success with their first TAVI, have index THV device failure, intend to undergo repeated TAVI and be considered suitable candidates by their local Heart Team. All patients will undergo a 30-day and 12-month follow-up. The estimated study completion is 2025. CONCLUSIONS: The registry will collect pre-, peri-, postoperative and 12-months data on patients undergoing repeated TAVI procedures with THVs for failure of the index THV and determine VARC-3-defined efficacy and safety at 30 days and functional outcome at 12 months. The registry will expand existing data sets and identify patient characteristics/indicators related to complications and clinical benefits for patients with symptomatic severe calcific degenerative aortic stenosis.

Heart failure is a pathological condition characterized by substantial prevalence and mortality, particularly in the Western world. Over recent decades, both pharmacological and non-pharmacological interventions have emerged, significantly enhancing patient survival and overall quality of life. Moreover, advancements in diverse imaging modalities facilitate precise diagnosis and comprehensive investigation into the fundamental etiology, enabling the development of more precise therapeutic approaches. Nonetheless, discernible gaps persist in comprehending specific facets of this condition, albeit persistent research endeavors seek to elucidate these inquiries.

INTRODUCTION AND OBJECTIVES: The optimal approach for persistent atrial fibrillation (AF) ablation remains unknown. In patients with persistent AF, we compared an ablation strategy based on pulmonary vein isolation (PVI) plus ablation of drivers (PVI+D), with a conventional PVI-only approach performed in a 1:1 propensity score-matched cohort. METHODS: Drivers were subjectively identified using conventional high-density mapping catheters (IntellaMap ORION, PentaRay NAV or Advisor HD Grid), without dedicated software, as fractionated continuous or quasicontinuous electrograms on 1 to 2 adjacent bipoles, which were ablated first; and as sites with spatiotemporal dispersion (the entire cycle length comprised within the mapping catheter) plus noncontinuous fractionation, which were only targeted in patients without fractionated continuous electrograms, or without AF conversion after ablation of fractionated continuous electrograms. Ablation included PVI plus focal or linear ablation targeting drivers. RESULTS: A total of 50 patients were included in each group (61±10 years, 25% women). Fractionated continuous electrograms were found and ablated in 21 patients from the PVI+D group (42%), leading to AF conversion in 7 patients. In the remaining 43 patients, 143 sites with spatiotemporal dispersion plus noncontinuous fractionation were targeted. Globally, AF conversion was achieved in 21 patients (42%). The PVI+D group showed lower atrial arrhythmia recurrences at 1 year of follow-up (30.6% vs 48%; P=.048) and at the last follow-up (46% vs 72%; P=.013), and less progression to permanent AF (10% vs 40%; P=.001). CONCLUSIONS: Subjective identification and ablation of drivers, added to PVI, increased 1-year freedom from atrial arrhythmia and decreased long-term recurrences and progression to permanent AF.
RESUMO
Background: Early discharge following ST-segment-elevation myocardial infarction (STEMI) confers notable advantages for both patients and healthcare systems. However, the adoption of a very early discharge strategy for selected patients remains limited due to safety considerations. We aimed to provide some insight into the safety of a discharge program with a hospital stay lasting <48 h after a primary percutaneous coronary intervention (PCI). Methods: Using a registry of 1105 patients undergoing primary PCI for STEMI in our hospital between January 2015 and October 2023, we enrolled all the patients who had a hospital stay ≤48 h, according to a prespecified institutional protocol. The primary objective was a combined rate of non-fatal stroke, non-fatal acute myocardial infarction, or cardiovascular death within 30 days of discharge. Emergency department visits or hospitalizations due to cardiovascular causes, along with the all-cause mortality, were measured during the same period. Results: A total of 453 (41%) patients were discharged ≤48 h after admission for a STEMI. The mean age was 62.4 (±12.5 years), 24.3% were women, and 17.9% were people with diabetes. Up to 96% of the procedures had been performed through radial artery access, and there were no major vascular complications. Regarding the primary endpoint, there was one event (0.2%; one patient suffered a non-fatal myocardial infarction). There were no cardiovascular deaths or deaths from other causes. Only five patients (1.1%) were re-hospitalized or visited the emergency department due to cardiovascular causes. Conclusions: An early discharge strategy for patients within 48 h of experiencing STEMI and undergoing primary PCI appears feasible and safe.
RESUMO
AIMS: Compensatory mechanisms in heart failure (HF) are triggered to maintain adequate cardiac output. Among them, hyperactivation of the sympathetic nervous system (SNS) is one of the main ones and carries a worse prognosis. The pupillary reflex depends on the SNS, and we can evaluate it through pupillometry. The aim of the study was to compare the differences in pupillary reflex between patients with acute HF and controls and to analyse whether these differences in pupillary reflex may offer a new and easy prognostic factor in such patients. METHODS AND RESULTS: We prospectively and consecutively included 107 patients admitted with decompensated HF. Quantitative pupillometry was performed with the NeuroOptics pupillometry during the first 24 h after admission and prior to discharge. The results were compared with those of a group of 100 healthy volunteers who also underwent pupillometry. The maximum baseline pupil size (MBPS) and the minimum pupil diameter (MPD) were measured. Patients with decompensated HF have a higher MBPS (3.64 ± 0.81) and higher MPD (2.60 ± 0.58) than HF patients at discharge and in the control group (P-value = 0.01 and 0.01, respectively). Also, HF patients presented an improvement in pupillometric values at discharge [MBPS (3.47 ± 0.79) and MPD (2.51 ± 0.58)] and showed no differences compared with the control group [MBPS (3.34 ± 0.82) and MPD (2.40 ± 0.53)] (P-value = 0.19 and 0.14, respectively). In addition, MBPS provides a good independent predictor of in-hospital and 1 month mortality in patients admitted with HF. Six patients (5.61%) died during hospital admission, and 11 patients (10.2%) died in the first month after discharge. Also, four patients (3.74%) were readmitted within 1 month of discharge. The receiver operating characteristic (ROC) curve for predicting in-hospital mortality through MBPS was 0.823. No patient with an MBPS < 3.7 mm died. The ROC curve for predicting combined mortality or readmission within the first month for MBPS was 0.698. CONCLUSIONS: Pupillometry may be a new, non-invasive, and simple tool to determine the status of SNS, help in the prognostic stratification of acute HF patients, and improve therapeutic management.

BACKGROUND: Cancer is an important condition associated with the development of atrial fibrillation (AF). The objectives of the BLITZ-AF Cancer study were to collect real-life information on the clinical profile and use of antithrombotic drugs in patients with AF and cancer to improve clinical management, as well as the evaluation of the association between different antithrombotic treatments (or their absence) and the main clinical events. METHODS: European multinational, multicenter, prospective, non-interventional study conducted in patients with AF (electrocardiographically confirmed) and cancer occurring within 3 years. The CHA2DS2-VASc and the HAS-BLED scores were calculated in all enrolled patients. RESULTS: From June 2019 to July 2021, 1514 patients were enrolled, 36.5% women, from 112 cardiology departments in 6 European countries (Italy, Belgium, the Netherlands, Spain, Portugal and Ireland). Italy enrolled 971 patients in 77 centers. Average age of patients was 74 ± 9 years, of which 20.9% affected by heart failure, 18.1% by ischemic heart disease, 9.8% by peripheral arterial disease and 38.5% by valvular diseases; 41.5% of patients had a CHA2DS2-VASc score ≥4. The most represented cancer sites were lung (14.9%), colorectal tract (14.1%), prostate (8.8%), or non-Hodgkin's lymphoma (8.1%). Before enrollment, 16.6% of patients were not taking antithrombotic therapy, while 22.7% were on therapy with antiplatelet agents and/or low molecular weight heparin. After enrollment these percentages decreased to 7.7% and 16.6%, respectively and, at the same time, the percentage of patients on direct oral anticoagulant (DOAC) therapy increased from 48.4% to 68.4%, also to the detriment of those on vitamin K antagonist therapy. CONCLUSIONS: The BLITZ-AF Cancer study, which enrolled patients diagnosed with AF and cancer, highlights that the use of DOACs by cardiologists in this clinical context has increased, even though the guidelines on AF do not give accurate indications about oral anticoagulant therapy in patients with cancer.

AIM: Severe functional tricuspid regurgitation (FTR) is associated with high risk of cardiovascular events, particularly heart failure (HF) and mortality. MicroRNAs (miRNAs) have been recently identified as novel biomarkers in different cardiovascular conditions, but no studies have focused on FTR. We sought to (1) to identify and validate circulating miRNAs as regulators of FTR and (2) to test association of miRNA with heart failure and mortality in FTR. METHODS AND RESULTS: Consecutive patients with isolated severe FTR (n = 100) evaluated in the outpatient Heart Valve Clinic and age- and gender-matched subjects with no TR (controls, n = 50) were prospectively recruited. The experimental design included (1) a screening phase to identify candidate miRNA differentially expressed in FTR (n = 8) compared with controls (n = 8) through miRNA array profiling of 192 miRNAs using quantitative reverse transcription PCR arrays [qRT-PCR]) and (2) a validation phase in which candidate miRNAs identified in the initial screening were selected for further validation by qRT-PCR in a prospectively recruited cohort of FTR (n = 92) and controls (n = 42). Bioinformatics analysis was used to predict their potential target genes and functional pathways elicited. A combined endpoint of hospital admission due to heart failure (HF) and all-cause mortality was defined. Initial screening identified 16 differentially expressed miRNAs in FTR compared with controls, subsequently confirmed in the validation phase (n = 16 were excluded due to significant haemolysis). miR-186-5p, miR-30e-5p, and miR-152-3p identified FTR with high predictive value [AUC of 0.93 (0.88-0.97), 0.83 (0.75-0.91) and 0.84 (0.76-0.92), respectively]. During a median follow-up of 20.4 months (IQR 8-35 months), 32% of FTR patients reached the combined endpoint. Patients with low relative expression of miR-15a-5p, miR-92a-3p, miR101-3p, and miR-363-3p, miR-324-3p, and miR-22-3p showed significantly higher rates of events (log-rank test for all P < 0.01). Both miR-15a-5p [hazard ratio: 0.21 (0.06-0.649, P = 0.007) and miR-92a-3p (0.27 (0.09-0.76), P = 0.01] were associated with outcomes after adjusting for age, gender, and New York Heart Association functional class. CONCLUSIONS: Circulating miRNAs are novel diagnostic and prognostic biomarkers in severe FTR. The quantification of miR-186-5p, miR-30e-5p, and miR-152-3p held strong diagnostic value, and the quantification of miR-15a-5p and miR-92a-3p are independently associated with outcomes. The recognition of specific miRNAs offers a novel perspective for TR evaluation.

BACKGROUND: Incomplete treatment of congestion often leads to worsening heart failure (HF). The remote dielectric sensing (ReDS) system is an electromagnetic energy-based technology that accurately quantifies changes in lung fluid concentration noninvasively. OBJECTIVES: This study sought to assess whether an ReDS-guided strategy during acutely decompensated HF hospitalization is superior to routine care for improving outcomes at 1 month postdischarge. METHODS: ReDS-SAFE HF (Use of ReDS for a SAFE discharge in patients with acute Heart Failure) was an investigator-initiated, multicenter, single-blind, randomized, proof-of-concept trial in which 100 patients were randomized to a routine care strategy, with discharge criteria based on current clinical practice, or an ReDS-guided decongestion strategy, with discharge criteria requiring an ReDS value of ≤35%. ReDS measurements were performed daily and at a 7-day follow-up visit, with patients and treating physicians in the routine care arm blinded to the results. The primary outcome was a composite of unplanned visits for HF, HF rehospitalization, or death at 1 month after discharge. RESULTS: The mean age was 67 ± 14 years, and 74% were male. On admission, left ventricular ejection fraction was 37% ± 16%, and B-type natriuretic peptide was 940 pg/L (Q1-Q3: 529-1,665 pg/L). The primary endpoint occurred in 10 (20%) patients in the routine care group and 1 (2%) in the ReDS-guided strategy group (log-rank P = 0.005). The ReDS-guided strategy group experienced a lower event rate, with an HR of 0.094 (95% CI: 0.012-0.731; P = 0.003), and a number of patients needed to treat of 6 to avoid an event (95% CI: 3-17), mainly resulting from a decrease in HF readmissions. The median length of stay was 2 days longer in the ReDS-guided group vs the routine care group (8 vs 6; P = 0.203). CONCLUSIONS: A ReDS-guided strategy to treat congestion improved 1-month prognosis postdischarge in this proof-of-concept study, mainly because of a decrease of the number of HF readmissions.

Right-sided heart failure and tricuspid regurgitation are common and strongly associated with poor quality of life and an increased risk of heart failure hospitalizations and death. While medical therapy for right-sided heart failure is limited, treatment options for tricuspid regurgitation include surgery and, based on recent developments, several transcatheter interventions. However, the patients who might benefit from tricuspid valve interventions are yet unknown, as is the ideal time for these treatments given the paucity of clinical evidence. In this context, it is crucial to elucidate aetiology and pathophysiological mechanisms leading to right-sided heart failure and tricuspid regurgitation in order to recognize when tricuspid regurgitation is a mere bystander and when it can cause or contribute to heart failure progression. Notably, early identification of right heart failure and tricuspid regurgitation may be crucial and optimal management requires knowledge about the different mechanisms and causes, clinical course and presentation, as well as possible treatment options. The aim of this clinical consensus statement is to summarize current knowledge about epidemiology, pathophysiology and treatment of tricuspid regurgitation in right-sided heart failure providing practical suggestions for patient identification and management.

BACKGROUND: The safety profile of transcatheter tricuspid valve (TTV) repair techniques is well established, but residual tricuspid regurgitation (TR) remains a concern. OBJECTIVES: The authors sought to assess the impact of residual TR severity post-TTV repair on survival. METHODS: We evaluated the survival rate at 2 years of 613 patients with severe isolated functional TR who underwent TTV repair in TRIGISTRY according to the severity of residual TR at discharge using a 3-grade (mild, moderate, and severe) or 4-grade scheme (mild, mild to moderate, moderate to severe, and severe). RESULTS: Residual TR was none/mild in 33%, moderate in 52%, and severe in 15%. The 2-year adjusted survival rates significantly differed between the 3 groups (85%, 70%, and 44%, respectively; restricted mean survival time [RMST]: P = 0.0001). When the 319 patients with moderate residual TR were subdivided into mild to moderate (n = 201, 33%) and moderate to severe (n = 118, 19%), the adjusted survival rate was also significantly different between groups (85%, 80%, 55%, and 44%, respectively; RMST: P = 0.001). Survival was significantly lower in patients with moderate to severe residual TR compared to patients with mild to moderate residual TR (P = 0.006). No difference in survival rates was observed between patients with no/mild and mild to moderate residual TR (P = 0.67) or between patients with moderate to severe and severe residual TR (P = 0.96). CONCLUSIONS: The moderate residual TR group was heterogeneous and encompassed patients with markedly different clinical outcomes. Refining TR grade classification with a more granular 4-grade scheme improved outcome prediction. Our results highlight the importance of achieving a mild to moderate or lower residual TR grade during TTV repair, which could define a successful intervention.

AIM: The RESHAPE-HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE-HF2 trial compared to those enrolled in the COAPT and MITRA-FR trials. METHODS AND RESULTS: The RESHAPE-HF2 study is an investigator-initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate-to-severe or severe FMR, for whom isolated mitral valve surgery was not recommended. Patients were randomized 1:1 to a strategy of delivering or withholding MitraClip. Of 506 patients randomized, the mean age of the patients was 70 ± 10 years, and 99 of them (20%) were women. The median EuroSCORE II was 5.3 (2.8-9.0) and median plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 2745 (1407-5385) pg/ml. Most patients were prescribed beta-blockers (96%), diuretics (96%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (82%) and mineralocorticoid receptor antagonists (82%). The use of sodium-glucose cotransporter 2 inhibitors was rare (7%). Cardiac resynchronization therapy (CRT) devices had been previously implanted in 29% of patients. Mean LVEF, left ventricular end-diastolic volume and effective regurgitant orifice area (EROA) were 31 ± 8%, 211 ± 76 ml and 0.25 ± 0.08 cm2, respectively, whereas 44% of patients had mitral regurgitation severity of grade 4+. Compared to patients enrolled in COAPT and MITRA-FR, those enrolled in RESHAPE-HF2 were less likely to have mitral regurgitation grade 4+ and, on average, HAD lower EROA, and plasma NT-proBNP and higher estimated glomerular filtration rate, but otherwise had similar age, comorbidities, CRT therapy and LVEF. CONCLUSION: Patients enrolled in RESHAPE-HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate-to-severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA-FR trials. The results of RESHAPE-HF2 will provide crucial insights regarding broader application of the transcatheter edge-to-edge repair procedure in clinical practice.

Resumen En la insuficiencia cardiaca terminal los síntomas predominantes habitualmente están relacionados con la congestión; sin embargo, la resistencia a diuréticos vía oral es frecuente y necesita tratamiento parenteral para paliar los síntomas. La administración intravenosa de furosemida requiere hospitalización o asistencia hospitalaria, lo que supone un deterioro significativo de la calidad de vida de pacientes en fases avanzadas de la enfermedad. La administración subcutánea continua de furosemida mediante infusor elastomérico es una técnica eficaz con baja tasa de complicaciones graves que permite la administración de diurético parenteral en el ámbito domiciliario, y evita la necesidad de hospitalizar. A pesar de que esta modalidad de tratamiento no está aceptada en ficha técnica y requiere más estudios que precisen su indicación, puede suponer un recurso adecuado para pacientes seleccionados. Se presenta el caso de una paciente con insuficiencia cardiaca avanzada, síntomas congestivos y ausencia de respuesta a tratamiento deplectivo vía oral, tratada con perfusión continua subcutánea domiciliaria de furosemida mediante infusor elastomérico de forma prolongada.
Abstract In end-stage heart failure the predominant symptoms are usually associated with congestion. However, the resistance to oral diuretics is common and requires parenteral treatment to alleviate the symptoms. The intravenous administration of furosemide requires hospital admission or hospital care. This leads to a significant decrease in the quality of life of patients in advance stages of the disease. The continuous subcutaneous infusion of furosemide using an elastomeric pump is an effective technique, with a low rate of serious complications that allows a parenteral diuretic to be administered in the home environment and thus avoiding the need for hospital admission. Despite this mode of treatment not being indicated in the drug data sheet, and requires more studies that specify its indication, it may be a suitable recourse for selected patients. It is presented a case of a patient with advanced heart failure, congestive symptoms, and a lack of response to oral diuretics treatment, and then treated with a continuous and prolonged subcutaneous infusion of furosemide at home using an elastomeric infusion pump.

INTRODUCCIÓN Y OBJETIVOS: A pesar de los avances en el tratamiento del infarto agudo de miocardio (IAM), este sigue presentando un pronóstico desfavorable. Hay poca evidencia acerca de la evolución de los pacientes con IAM y la enfermedad coronavírica de 2019 (COVID-19). El objetivo del estudio es describir la presentación clínica, las complicaciones y los factores predictores de mortalidad hospitalaria en pacientes con IAM durante el brote de COVID-19 en España. MÉTODOS: Se realizó un estudio de cohortes, prospectivo y multicéntrico de todos los pacientes consecutivos con IAM en tratamiento invasivo durante el brote de COVID19 (15 de marzo a 15 de abril de 2020). Se compararon las características clínicas de los pacientes positivos para COVID-19 con las de los negativos, y se evaluó el efecto de la COVID-19 en la mortalidad mediante emparejamiento por puntuación de propensión y regresión logística. RESULTADOS: Se incluyó a 187 pacientes con IAM: 111 con elevación del segmento ST y 76 sin elevación. De ellos, 32 (17%) resultaron positivos para COVID-19. Las puntuaciones GRACE y Killip-Kimball y varios marcadores inflamatorios resultaron significativamente mayores en los pacientes con COVID-19. La mortalidad total y cardiovascular fueron significativamente mayores en los pacientes con COVID-19 (el 25 frente al 3,8%; p < 0,001; y el 15,2 frente al 1,8%; p = 0,001). La puntuación GRACE > 140 (OR = 23,45; IC95%, 2,52-62,51; p = 0,005) y la COVID-19 (OR = 6,61; IC95%, 1,82-24,43; p = 0,02) resultaron factores independientes de mortalidad hospitalaria. CONCLUSIONES: Durante el brote epidémico, la puntuación GRACE elevada y la COVID19 fueron los factores independientes de mortalidad hospitalaria en los pacientes con IAM
INTRODUCTION AND OBJECTIVES: Despite advances in treatment, patients with acute myocardial infarction (AMI) still exhibit unfavorable short- and long-term prognoses. In addition, there is scant evidence about the clinical outcomes of patients with AMI and coronavirus disease 2019 (COVID-19). The objective of this study was to describe the clinical presentation, complications, and risk factors for mortality in patients admitted for AMI during the COVID-19 pandemic. METHODS: This prospective, multicenter, cohort study included all consecutive patients with AMI who underwent coronary angiography in a 30-day period corresponding chronologically with the COVID-19 outbreak (March 15 to April 15, 2020). Clinical presentations and outcomes were compared between COVID-19 and non-COVID-19 patients. The effect of COVID-19 on mortality was assessed by propensity score matching and with a multivariate logistic regression model. RESULTS: In total, 187 patients were admitted for AMI, 111 with ST-segment elevation AMI and 76 with non-ST-segment elevation AMI. Of these, 32 (17%) were diagnosed with COVID-19. GRACE score, Killip-Kimball classification, and several inflammatory markers were significantly higher in COVID-19-positive patients. Total and cardiovascular mortality were also significantly higher in COVID-19-positive patients (25% vs 3.8% [P < .001] and 15.2% vs 1.8% [P = .001], respectively). GRACE score > 140 (OR, 23.45; 95%CI, 2.52-62.51; P = .005) and COVID-19 (OR, 6.61; 95%CI, 1.82-24.43; P = .02) were independent predictors of in-hospital death. CONCLUSIONS: During this pandemic, a high GRACE score and COVID-19 were independent risk factors associated with higher in-hospital mortality

Introducción y objetivos: Analizar el coste-efectividad del edoxabán frente al acenocumarol en la prevención del ictus y la embolia sistémica en pacientes con fibrilación auricular no valvular (FANV) en España. Métodos: Modelo de Markov, adaptado a España desde la perspectiva del Sistema Nacional de Salud, que simula la evolución de una cohorte hipotética de pacientes con FANV a lo largo de toda su vida a partir de diferentes estados de salud: ictus, hemorragias y otras complicaciones cardiovasculares. Los datos de eficacia y seguridad se obtuvieron a partir de la evidencia clínica disponible (principalmente del estudio en fase III ENGAGE AF-TIMI 48). Los costes del tratamiento de la FANV y sus complicaciones se obtuvieron de fuentes españolas. Resultados: El edoxabán resultó en 0,34 años de vida ajustados por calidad (AVAC) adicionales en comparación con el acenocumarol. El coste incremental con el edoxabán fue de 3.916 euros, derivado principalmente de un mayor coste farmacológico, que se compensa parcialmente por los menores costes de la monitorización del tratamiento y del tratamiento de eventos y complicaciones de la FANV. Se obtuvo un coste por AVAC de 11.518 euros, dentro de los umbrales comúnmente considerados coste-efectivos en España (25.000-30.000 euros/AVAC). Los diferentes análisis de sensibilidad realizados confirmaron la robustez de los resultados. Conclusiones: El edoxabán es una alternativa coste-efectiva frente al acenocumarol en la prevención del ictus y la embolia sistémica en pacientes con FANV en España
Introduction and objectives: To assess the cost-effectiveness of edoxaban versus acenocoumarol in the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation (NVAF) in Spain. Methods: Markov model, adapted to the Spanish setting from the perspective of the National Health System, stimulating the progression of a hypothetical cohort of patients with NVAF throughout their lifetime, with different health states: stroke, hemorrhage, and other cardiovascular complications. Efficacy and safety data were obtained from the available clinical evidence (mainly from the phase III ENGAGE AF-TIMI 48 study). The costs of managing NVAF and its complications were obtained from Spanish sources. Results: Edoxaban use led to 0.34 additional quality-adjusted life years (QALY) compared with acenocoumarol. The incremental cost with edoxaban was €3916, mainly because of higher pharmacological costs, which were partially offset by lower costs of treatment monitoring and managing NVAF events and complications. The cost per QALY was €11 518, within the thresholds commonly considered cost-effective in Spain (€25 000-€30 000/QALY). The robustness of the results was confirmed by various sensitivity analyses. Conclusions: Edoxaban is a cost-effective alternative to acenocoumarol in the prevention of stroke and systemic embolism in patients with NVAF in Spain

Resumen Los nuevos anticoagulantes orales suponen una atractiva alternativa para los clásicos antagonistas de la vitamina K (AVKs) en la prevención de ictus en pacientes con fibrilación auricular no valvular. A diferencia de los AVKs, estos anticoagulantes no requieren monitorización ni ajuste de dosis y poseen propiedades farmacológicas favorables. La falta de antídoto efi caz, su coste, o dudas en cuanto a la seguridad en los pacientes con enfermedad renal avanzada pueden explicar su lento ritmo de expansión. El uso seguro y eficaz de estos nuevos medicamentos depende en gran medida de la experiencia clínica entre la comunidad médica. Esta revisión discute las peculiaridades de los nuevos anticoagulantes orales, propor cionando algoritmos prácticos y fáciles de usar para su aplicación en la práctica clínica diaria.
Abstract New oral anticoagulants suppose an attractive alternative for classical vitamin K antagonists (AVKs) in stroke prevention for patients with non-valvular atrial fibrillation. Unlike AVKs, these anticoagulants do not require monitoring or dose adjustment and have favourable pharmacological properties. The lack of an effective antidote, its cost, or doubts regarding the safety of patients with advanced kidney disease may explain its slow rate of expansion. The safe and effective use of these new medications depends largely on clinical experience among the medical community. This review discusses the peculiarities of the new oral anticoagulants, providing practical and easy-to-use algorithms for their application in daily clinical practice.
