RESUMO

INTRODUCTION: Acute aortic dissection (AAD) is a devastating surgical emergency, with high operative mortality. Several scoring algorithms have been used to establish the expected mortality in these patients. Our objective was to define the predictive factors for mortality in our center and to validate the EuroSCORE and Penn classification system. METHODS: Patients who underwent surgery for AAD from 2006 to 2016 were retrieved from the institution's database. Preoperative, operative and postoperative variables were collected. Observed and expected mortality was calculated by EuroSCORE. Logistic regression analysis and Cox regression analysis were performed to find predictors of operative mortality and survival, respectively. The receiver operating characteristic (ROC) curves were plotted for logistic EuroSCORE, and the area under the ROC curve (AUC) was calculated. RESULTS: 87 patients (27.6% female) underwent surgery for AAD. The mean age was 58.6±9.7 years. Expected and observed operative mortality was 25.8±15.1% and 20.7%, respectively. Penn Aa, Ab and Abc shared similar observed/expected (O/E) mortality ratio. The only independent predictor of operative mortality (OR: 3.63; 95% CI: 1.19-11.09) and survival (HR: 2.6; 95% CI: 1.5-4.8) was female gender. EuroSCORE showed a very poor prediction capacity, with an AUC=0.566. CONCLUSION: Female gender was the only independent predictor of operative mortality and survival in our institution. EuroSCORE is a poor scoring algorithm to predict mortality in AAD, but with consistent results for Penn Aa, Ab and Abc.

RESUMO

OBJECTIVES: The timing for surgical treatment in patients with primary organic severe mitral valve regurgitation (MR) and preserved left ventricular ejection fraction (LVEF) systolic is a challenge since it depends upon LV end systolic dimension (LVESD) and LVEF which may be late markers of LV dysfunction. Echocardiography is the most important tool in the diagnosis of mechanisms, etiology, severity and hemodynamic consequences of mitral regurgitation. The global longitudinal strain (GLS), a new and sensitive method for the detection of LV dysfunction, might be a useful method for the evaluation of preclinical systolic dysfunction. Nevertheless, its role for predicting postoperative outcomes is not well established. METHODS: A meta-analysis was performed to address the role of GLS in patients with severe mitral regurgitation and preserved LVEF who underwent mitral surgery. We included studies that compared outcomes according to preoperative GLS in regard to survival and postoperative LV function. RESULTS: We included 2358 patients enrolled in 8 studies. Patients with reduced GLS% had worse long term survival after mitral valve surgery (HR=1.13, 95%CI: 1.02-1.26). Patients with preoperatively reduced GLS% had lower LVEF after surgery (MD= -5.06%, 95%CI: -8.97%-1.16%) and additionally, patients who presented postoperative LVEF dysfunction had worse preoperative GLS (MD=4.33, 95%CI: 3.89-4.76). CONCLUSION: In patients with primary mitral regurgitation, preoperative GLS is a predictor for long term survival and postoperative LVEF. It is a useful parameter to be included when considering early surgery in patients with severe mitral regurgitation and normal LVEF.

RESUMO

OBJECTIVE: To evaluate the clinical and echocardiographic outcomes in aortic valve replacement (AVR) patients with aortic bioprosthesis under oral anticoagulation (OA). METHODS: Patients who underwent AVR with bioprosthesiswere prospectively enrolled. They were classified based on postoperative use of OA. Clinical and operative variables were collected. Echocardiographic and clinical follow-ups were performed two years after surgery. The primary outcome evaluated was change in transprosthetic gradient. Secondary outcomes analyzed were change in New York Heart Association (NYHA) class, major bleeding episodes, hospitalization, stroke, and transient ischemic attack. RESULTS: We included 103 patients (61 without OA and 42 with OA). Clinical characteristics were similar among groups, except for younger age (76±6.3 vs. 72.4±8.1 years, P=0.016) and higher prevalence of atrial fibrillation (0% vs. 23.8%, P<0.001) in the OA group. Mean (21.4±10 mmHg vs. 16.8±7.7 mmHg, P=0.037) and maximum (33.4±13.7 mmHg vs. 28.4±10.2 mmHg, P=0.05) transprosthetic gradients were higher in patients without OA. Improvement in NYHA class was more frequent in patients with OA (73% vs. 45.3%, P=0.032). Major bleeding, stroke, and hospitalization were similar among groups. OA was the only independent predictor for improvement of NYHA class after multivariate logistic regression analysis (odds ratio [OR]: 5.9, 95% confidence interval [CI]: 1.2-29.4; P=0.028). Stratification by prosthesis size showed that patients with ≤ 21 mm prosthesis benefited from OA. CONCLUSION: Early anticoagulation after AVR with bioprosthesis was associated with significant decrease of transprosthesis gradient and improvement in NYHA class. These associations were seen mainly in patients with ≤ 21 mm prosthesis.

RESUMO

BACKGROUND: Transit-time flow measurement (TTFM) is the gold standard for intraoperative detection of graft failure. Several reports show that TTFM and distal coronary bed quality (DCBQ) may also be useful for midterm detection of graft failure. Nonetheless, there are no data regarding their predictive role on long-term outcomes. METHODS: Patients with three-vessel disease who underwent isolated coronary artery bypass grafting (CABG) in 2006 and received at least one graft to the left anterior descending artery (LAD) or to the first obtuse marginal (OM1) or posterior descending artery (PDA) were included. Baseline characteristics, mean graft flow, pulsatility index, and subjective impression of DCBQ for each coronary territory were collected. Long-term cardiovascular (CV) and overall survival, operative mortality, and new percutaneous coronary intervention (PCI) were evaluated. RESULTS: A total of 177 patients underwent isolated CABG. The OM1 was grafted in 131 patients, the LAD in 169 patients, and the PDA in 100 patients. Neither DQCB nor TTFM were predictors for new PCI. Independent predictors for overall survival were age, previous acute myocardial infarction (AMI), and DQCB of OM1 (odds ratio [OR] = 2.97; 95% confidence interval [CI]: 1.15-7.71). Age, previous AMI, and DCBQ of OM1 (OR = 2.5; 95% CI: 1.39-4.81) were independent predictors for CV survival. CONCLUSIONS: TTFM on patients with functioning grafts does not predict long-term survival or performance of new PCI. Subjective evaluation of distal coronary bed, especially of the OM1, has a strong impact on long-term outcomes.

RESUMO

Resumen: Introducción: la pandemia COVID-19 ha determinado la aplicación de medidas sanitarias de emergencia, tendientes a evitar la progresión a nivel nacional. Reportes internacionales han sugerido que dichas medidas determinaron secundariamente una desatención en otras patologías, principalmente cardiovasculares, y eventual aumento de paros cardíacos extrahospitalarios (PCEH). Objetivo: determinar la frecuencia de consultas en emergencia por dolor precordial a nivel nacional y de PCEH asistidos por los principales servicios de emergencia prehospitalaria (SEP) de Montevideo, durante la pandemia. Método: se solicitó información del número de consultas por dolor precordial y de consultas totales, a las instituciones médicas de Montevideo y del interior del país, realizadas en el período comprendido entre el 13 de marzo y el 30 de abril de los años 2018, 2019 y 2020. Se solicitó a los SEP información sobre la frecuencia de PCEH en Montevideo durante los mismos períodos. Los datos se expresan como frecuencia absoluta y tasa de incidencia (por 100.000 afiliados) con su intervalo de confianza estimado mediante Fisher. Resultados: el número de consultas por dolor precordial fue estable durante el período 2018-2019. Durante 2020, dichas consultas disminuyeron, representando entre 11,3% y 21,7% del total de consultas. Se evidenció un aumento no significativo en la tasa de PCEH en el 2020 (9,05, IC95%: 7,15-11,30) comparado con el 2019 (7,94, IC95%: 6,19-10,04) y 2018 (7,43, IC95%: 5,75-9,45). Conclusiones: los datos crudos presentados muestran que desde el 13 de marzo hasta el 30 de abril de 2020 hubo una disminución en las consultas en emergencia por dolor precordial, aumentando de forma no significativa el número de PCEH durante el mes de abril, respecto al mismo período de los dos años anteriores.


Summary: Introduction: the COVID-19 pandemic has determined the application of emergency health measures aimed at preventing progression at national level. International reports have suggested that these measures lead to a lack of care in other pathologies, mainly cardiovascular, and eventually increase out-of-hospital cardiac arrests. Objective: to determine the frequency of emergency consultation for chest pain and out-of-hospital cardiac arrests, assisted by the main pre-hospital emergency services of Montevideo, during the COVID-19 pandemic. Methods: information was requested to the medical institutions of Montevideo and all over the country, on the number of consultations for chest pain and total consultations, in the period March 13- April 30 of 2018, 2019 and 2020. The frequency of out-of-hospital cardiac arrests in Montevideo was requested to the pre-hospital emergency services during the same period. The data is expressed as absolute frequency and incidence rates (x 100,000) with its 95% CI calculated by Fisher. Results: the number of consultations for precordial pain was stable during the 2018-2019 period. During 2020, these consultations decreased and represented between 11.3% and 21.7% of the total number of consultations. Out-of-hospital cardiac arrests showed a non significant increase in its incidence rate in 2020 (9.05, 95%IC: 7.15-11.30) compared with 2019 (7.94, 95%IC: 6.19-10.04) and 2018 (7.43, 95%IC: 5.75-9.45). Conclusions: the raw data presented shows that from March 13 to April 30 of 2020, there was a decrease in emergency visits for precordial pain and a non-significant increase in the incidence rate of out-of-hospital cardiac arrests.


Resumo: Introdução: a pandemia do COVID-19 determinou a aplicação de medidas emergenciais de saúde destinadas a impedir a progressão em nível nacional. Relatórios internacionais sugerem que essas medidas levam à falta de atendimento em outras patologias, principalmente cardiovasculares, e eventualmente aumentam as paradas cardíacas fora do hospital. Objetivo: determinar a frequência da consulta de emergência para dor no peito e paradas cardíacas fora do hospital, assistidas pelos principais serviços de emergência pré-hospitalar de Montevidéu, durante a pandemia do COVID-19. Métodos: foram solicitadas informações às instituições médicas de Montevidéu e de todo o país sobre o número de consultas para dor no peito e total de consultas, no período de 13 de março a 30 de abril de 2018, 2019 e 2020. A frequência de -as paradas cardíacas no hospital foram solicitadas aos serviços de emergência pré-hospitalares durante o mesmo período. Os dados são expressos como frequência absoluta e taxa de incidência (x 100.000) com seu intervalo de confiança estimado por Fisher. Resultados: o número de consultas para dor precordial permaneceu estável no período 2018-2019. Durante 2020, essas consultas representaram entre 11,3% e 21,7% do número total de consultas. Um aumento não significativo da taxa de paradas cardíacas fora do hospital foi evidente em 2020 (9,05, IC 95%: 7,15-11,30) em comparação com 2019 (7,94, IC 95%: 6,19-10,04) e 2018 (7,43, 95%IC: 5,75-9,45), o que não é significativo. Conclusões: os dados brutos apresentados mostram que de 13 de março a 30 de abril de 2020 houve uma diminuição nas visitas de emergência por dor precordial, não aumentando significativamente o número de paradas cardíacas fora do hospital em comparação aos dois anos anteriores.

RESUMO

Resumen: Antecedentes: la endocarditis infecciosa es una enfermedad con elevada morbimortalidad, la cual se encuentra en torno al 25%. Aproximadamente el 50% de los casos requiere tratamiento quirúrgico. En nuestro medio se desconocen las características clínicas y evolutivas de pacientes operados por endocarditis infecciosa activa. Objetivos: primario, determinar mortalidad operatoria (MO) y sobrevida a largo plazo; secundario, definir predictores de embolias, complicaciones locales (CL), MO y endocarditis protésica (EP) en la evolución. Métodos: trabajo retrospectivo y analítico. Se identificaron pacientes que recibieron cirugía cardíaca por endocarditis activa entre enero de 2006 y diciembre de 2017. Mediante regresión logística multivariada se identificaron predictores para los objetivos enunciados. Resultados: se incluyeron 101 pacientes. El microorganismo más frecuentemente encontrado fue Staphylococcus aureus (SA) (15,8%). La topografía fue protésica en 20,8%, aórtica en 46,5%, mitral en 23,8% y mitro-aórtica en 13,9%. La MO fue 11,3% y 29,5% (p=0,025), según ausencia o presencia de CL, único predictor independiente de mortalidad (OR=3,38). El 47,5% presentó CL, siendo la más frecuente el absceso (25,7%). Fueron predictores independientes: EP (OR=5,8), endocarditis valvular aórtica (OR=2,9) y sexo masculino (OR=3,5). La incidencia de EP precoz fue 3% y tardía 4%. El 30% de los pacientes adquirió la EI como consecuencia de un procedimiento médico invasivo en los 6 meses previos. De los siete pacientes con EP en la evolución, seis tenían CL (p<0,05). El 31,7% presentaba embolias, resultando predictores independientes: Staphylococcus aureus (OR=4,6), vegetación en el velo mitral posterior (OR=3,2) y antecedente de hipertensión arterial (OR=3,32). La sobrevida a cinco y diez años fue de 88,20%±0,04 y 81,50%±0,05 respectivamente. Conclusiones: la MO de la endocarditis activa en nuestro medio es similar a la reportada internacionalmente. La presencia de CL se asocia a EP en la evolución y resultó ser un predictor independiente de sobrevida a largo plazo, y de MO. La sobrevida a largo plazo es similar a la reportada internacionalmente. Se observó una alta incidencia de agentes intrahospitalarios y procedimientos invasivos como causas probables.


Summary: Introduction: infective endocarditis is a high morbidity and mortality disease, which is about 25%. About fifty percent of patients require heart surgery. In our environment, clinical and evolutionary characteristics of patients operated with active endocarditis are unknown. Objective: primary, determine operative mortality and long-term survival; secondary, define predictors of embolisms, local complications, operative mortality and prosthetic endocarditis in evolution. Methods: retrospective, analytical study. Patients who received cardiac surgery for active endocarditis between January 2006 and December 2017 were identified. Through multivariate logistic regression, predictors were identified for the stated objectives. Results: one hundred and one patients were included. The most frequently found microorganism was Staphylococcus aureus (15.8%). The topography was prosthetic in 20.8%, aortic 46.5%, mitral 23.8% and mitro-aortic 13.9%. The operative mortality was 11.3% and 29.5% (p = 0.025) according to the absence or presence of local complications , the only independent predictor of mortality (OR = 3.32). Local complications were present in 47.5%, the most frequent were abscess (25.7%), independent predictors were: prosthetic endocarditis (OR=5.8), aortic endocarditis (OR=2.9) and male sex (OR=3.5). The incidence of early prosthetic endocarditis was 3% and late 4%. Thirty percent of patients acquired infective endocarditis as a result of an invasive medical procedure in the previous 6 months. Of the seven patients with prosthetic endocarditis in evolution, six had local complications (p <0.05). Embolic events were present in 31.7% of patients, were independent predictors: Staphylococcus aureus (OR=4.6), presence of vegetation in the posterior mitral leaflet (OR=3.2) and history of hypertension (OR=3.32). Survival at 5 and 10 years was 88.20% ± 0.04 and 81.50% ± 0.05 respectively. Conclusions: operative mortality of active endocarditis in our environment is high and similar to that reported internationally. The presence of local complications is associated with prosthetic endocarditis in evolution and proved to be an independent predictor of long-term survival, and operative mortality. Long-term survival is similar to that reported internationally. A high incidence of in-hospital agents was observed and invasive procedures as probable causes.


Resumo: Antecedentes: a endocardite infecciosa é uma doença com alta morbimortalidade. Requerem tratamento cirúrgico o 50%. Em nosso meio, as características clínicas e evolutivas dos pacientes operados com endocardite ativa são desconhecidas. Objetivos: primário, determinar a mortalidade operatória e a sobrevida a longo prazo; secundário: Definir preditores de embolias, complicações locais, mortalidade operatória e endocardite protética na evolução. Métodos: trabalho retrospectivo, analítico. Foram identificados no banco de dados pacientes submetidos à cirurgia de endocardite ativa entre janeiro de 2006 e dezembro de 2017. Através de regressão logística multivariada, os preditores foram identificados para os objetivos estabelecidos. Resultados: cento e um pacientes foram incluídos. Staphylococcus aureus foi o microrganismo mais frequente (15,8%). A topografia foi protética em 20,8%, aórtica 46,5%, mitral 23,8% e mitroaórtica 13,9%. A mortalidade operatória foi de 11,3% e 29,5% (p = 0,025), de acordo com a ausência ou presença de complicações locais, o único preditor independente de mortalidade (OR). Um 47,5% apresentaram complicações locais, sendo o mais frequente o abscesso (25,7%). Os preditores independentes foram: endocardite protética (OR = 5,8), endocardite valvar aórtica (OR=2,9)) e sexo masculino (OR = 3,5). A incidência de endocardite protética precoce foi de 3% e tardia de 4%. Trinta por cento dos pacientes adquiriram endocardite infecciosa como resultado de um procedimento médico invasivo nos 6 meses anteriores. Dos pacientes com endocardite protética na evolução, 85,7% apresentava complicações locais (p <0,05). O 31,7% apresentava embolia, resultando em preditores independentes: Staphylococcus aureus (OR = 4,6), vegetação no véu mitral posterior (OR = 3,2) e história de hipertensão arterial (OR = 3,32). A sobrevida em 5 e 10 anos foi de 88,20% ± 0,04 e 81,50% ± 0,05, respectivamente. Conclusões: a mortalidade operatória da endocardite ativa em nosso ambiente é alto e semelhante ao relatado internacionalmente. A presença de complicações locais está associada à endocardite protética na evolução e provou ser um preditor independente de sobrevida a longo prazo e mortalidade operatória. A sobrevivência a longo prazo é semelhante à relatada internacionalmente. Foi observada alta incidência de agentes hospitalares e procedimentos invasivos como causas prováveis.

RESUMO

Resumen: Introducción: la fibrilación auricular (FA) es la arritmia sostenida más frecuente en la práctica clínica. Asocia un aumento significativo de morbimortalidad. La prevención de fenómenos embólicos es un pilar del tratamiento, basado en gran medida en la anticoagulación oral (ACO). Hay un porcentaje significativo de pacientes que presentan contraindicaciones para ACO, a los cuales se deben ofrecer tratamientos alternativos. La exclusión quirúrgica del apéndice auricular izquierdo (AAI) determina beneficios en tal sentido y se asocia a una menor tasa de eventos neurológicos. Objetivo: primario, valorar la seguridad de la exclusión quirúrgica del AAI en pacientes con FA sometidos a cirugía valvular mitral; secundario, analizar la incidencia de ataque cerebrovascular (ACV) en dicha población y analizar la sobrevida entre los pacientes con y sin exclusión del AAI. Método: estudio unicéntrico, analítico, observacional, retrospectivo, comparando exclusión o no del AAI en pacientes con FA sometidos a cirugía cardíaca sobre válvula mitral, entre enero de 2012 y diciembre de 2018. Las variables se obtuvieron de la base de datos institucional. El seguimiento fue telefónico y la sobrevida fue derivada de datos oficiales nacionales. Resultados: se incluyeron 69 pacientes (en 45 se realizó exclusión del AAI). Como características con diferencias significativas destacan la edad (69,1±8,2 años sin exclusión del AAI; 63,6±10,3 años con exclusión del AAI, p=0,026) y el porcentaje de ablación quirúrgica de FA en cada grupo (29,2% sin exclusión del AAI; 68,9% con exclusión del AAI, p=0,002). Se obtuvo un seguimiento de 33 pacientes, entre los cuales no hubo diferencias significativas en los parámetros considerados. Se evaluó la sobrevida del total de los pacientes incluidos, sin diferencia a largo plazo. Conclusión: según los datos analizados, la exclusión del AAI es un procedimiento seguro que no agrega complicaciones a la cirugía valvular mitral en pacientes con FA. No fue posible demostrar que la exclusión del AAI reduzca de manera significativa la prevalencia de ACV isquémico a largo plazo, ni modifique la sobrevida.


Summary: Introduction: atrial fibrillation is the most common sustained cardiac arrythmia in clinical practice. It is associated to significant morbimortality. The prevention of embolic episodes is a pillar of atrial fibrillation treatment and is based mainly on anticoagulation. However, there is a significant proportion of patients with contraindications for anticoagulation, to whom alternative treatments must be offered. Surgical exclusion of the left atrial appendage offers benefits in this regard, and is associated to a lower rate of neurological events. Objective: primary endpoint: to evaluate the safety of the surgical exclusion of the left atrial appendage in patients with atrial fibrillation undergoing mitral valve surgery; secondary endpoint: to analyze the incidence of stroke in this population, and to analyze the survival rate in patients with and without left atrial appendage exclusion. Method: a single center, analytic, observational, retrospective study, comparing exclusion and no exclusion of the left atrial appendage in patients with atrial fibrillation undergoing mitral valve surgery between January 2012 and December 2018. The variables were obtained from the institutional database. The follow up was telephonic and survival rates were obtained from a national official database. Results: 69 patients were included (45 underwent surgical left atrial appendage exclusion). Statistically significant features between the groups were age (69.1±8.2 years without left atrial appendage exclusion; 63.6±10.3 years with left atrial appendage exclusion, p=0.026), and the rate of surgical ablation of atrial fibrillation (29.2% without exclusion; 68.9% with exclusion, p=0.002). The follow up was carried out in 33, finding no statistically significant differences between the groups. The survival rate of all patients was analyzed, finding no long term differences. Conclusion: according to the data analyzed, left atrial appendage exclusion is a safe procedure, and adds no further complications to mitral valve surgery in patients with atrial fibrillation. It was not possible to prove that left atrial appendage exclusion significantly reduces the long term prevalence of ischemic stroke or modifies the survival rate.

Como elementos estatisticamente significativos, destacam-se a idade (69,1 ± 8,2 anos sem exclusão do apêndice atrial esquerdo; 63,6 ± 10,3 anos com exclusão do apêndice atrial esquerdo, p = 0,026) e a taxa de ablação cirúrgica da fibrilação atrial em cada grupo (29,2% sem exclusão; 68,9% com exclusão, p = 0,002). Foi obtido um seguimento de 33 pacientes, entre os quais não houve diferenças significativas nos parâmetros considerados. A sobrevida de todos os pacientes incluídos foi avaliada, sem diferença na sobrevida a longo prazo. Conclusão: de acordo com os dados analisados, a exclusão do apêndice atrial esquerdo é um procedimento seguro que não agrega complicações à cirurgia valvar mitral em pacientes com fibrilação atrial. Não foi possível demonstrar que a exclusão da apêndice atrial esquerdo reduz significativamente a prevalência de ataque vascular cerebral isquêmico a longo prazo, nem modifica a sobrevida.

RESUMO

Resumen: La pandemia generada por el SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus) ha constituido un desafío mundial. En momentos de dificultad como los que se han presentado recientemente, es aún más necesaria la investigación para avanzar en el diagnóstico y tratamiento de las diferentes patologías. Utilizando el amplio desarrollo de los medios de comunicación, este año el Congreso del Colegio Americano de Cardiología (ACC por su sigla en inglés) se celebró del 28 al 30 de marzo en un formato virtual, permitiendo a profesionales de todo el mundo acceder a múltiples actividades científicas con el mismo nivel de excelencia que en las sesiones presenciales. Realizaremos un breve resumen de alguno de los principales trabajos científicos presentados: - Tailored Antiplatelet Initiation to Lessen Outcomes Due to Decreased Clopidogrel Response after Percutaneous Coronary Intervention: TAILOR-PCI. - Rivaroxaban in Peripheral Artery Disease after Revascularization: VOYAGER PAD trial. - Vericiguat in Patients with Heart Failure and Reduced Ejection Fraction: VICTORIA Study Group. - The Evolut Low Risk Bicuspid Study. - PARTNER 3. Two-year clinical and echocardiographic outcomes. - Ticagrelor with and without Aspirin in Acute Coronary Syndrome After PCI: the TICO Trial - Apixaban for the Treatment of Venous Thromboembolism Associated with Cancer: Caravaggio trial. - Ten-year Outcomes After Drug-eluting Stents Versus Coronary Artery Bypass Grafting for Left Main Coronary Disease: Extended Follow Up of the PRECOMBAT Trial. - Anticoagulation with or without Clopidogrel after Transcatheter Aortic-Valve Implantation: POPular TAVI.


Summary The SARS-CoV-2 pandemic has been a global challenge. In times of difficulty such as those that have recently arisen, research is even more necessary to advance in the diagnosis and treatment of different pathologies. Using the extensive development of the media, this year the American Congress of Cardiology was held from March 28 to 30 in a virtual format, allowing professionals from around the world to access multiple scientific activities with the same level of excellence as in face-to-face sessions. We will make a brief summary of some of the main scientific papers presented: - Tailored Antiplatelet Initiation to Lessen Outcomes Due to Decreased Clopidogrel Response after Percutaneous Coronary Intervention: TAILOR-PCI. - Rivaroxaban in Peripheral Artery Disease after Revascularization: VOYAGER PAD trial:. - Vericiguat in Patients with Heart Failure and Reduced Ejection Fraction: VICTORIA Study Group. - The Evolut Low Risk Bicuspid Study. - PARTNER 3. Two-year clinical and echocardiographic outcomes. - Ticagrelor with and without Aspirin in Acute Coronary Syndrome After PCI: the TICO Trial. - Apixaban for the Treatment of Venous Thromboembolism Associated with Cancer: Caravaggio trial. - Ten-year Outcomes After Drug-eluting Stents Versus Coronary Artery Bypass Grafting for Left Main Coronary Disease: Extended Follow Up of the PRECOMBAT Trial. - Anticoagulation with or without Clopidogrel after Transcatheter Aortic-Valve Implantation: POPular TAVI.

RESUMO

Resumen: La trombosis de la válvula protésica biológica (TVPB) era considerada una entidad relativamente rara. Sin embargo, debido al aumento del uso de bioprótesis en cirugía cardíaca y al advenimiento de las prótesis biológicas transcatéter, ha adquirido mayor interés al ser reconocida como causa de disfunción protésica. Aún no se ha establecido la relevancia a largo plazo de la trombosis subclínica, ni están definidas las estrategias terapéuticas óptimas para prevenir la TVPB ni las complicaciones tromboembólicas. En esta revisión se analizan la fisiopatología, el diagnóstico y el tratamiento de la TVPB para contribuir al conocimiento de esta patología.


Summary: Bioprosthetic valve thrombosis was considered a relatively rare entity. However, due to the increased use of bioprostheses in cardiac surgery and the advent of transcatheter biological prostheses, it has acquired more attention as a cause of prosthetic dysfunction. The long-term relevance of subclinical thrombosis has not yet been elucidated, nor are the optimal therapeutic strategies to prevent bioprosthetic valve thrombosis or thromboembolic complications. This review aims to provide a summary of the pathophysiology, diagnosis and treatment of bioprosthetic valve thrombosis to contribute to the knowledge of this pathology.
