RESUMO

OBJECTIVES: To evaluate the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with and without prior coronary artery bypass graft (CABG) surgery. BACKGROUND: Data on the outcomes of CTO PCI in patients with versus without CABG remains limited and with scarce representation from developing regions like Latin America. METHODS: We evaluated patients undergoing CTO PCI in 42 centers participating in the LATAM CTO registry between 2008 and 2020. Statistical analyses were stratified according to CABG status. The outcomes of interest were technical and procedural success and in-hospital major adverse cardiac and cerebrovascular events (MACCE). RESULTS: A total of 1662 patients were included (n = 1411 [84.9%] no-CABG and n = 251 [15.1%] prior-CABG). Compared with no-CABG, those with prior-CABG were older (67 ± 11 vs. 64 ± 11 years; p < 0.001), had more comorbidities and lower left ventricular ejection fraction (52.8 ± 12.8% vs. 54.4 ± 11.7%; p = 0.042). Anatomic complexity was higher in the prior-CABG group (J-CTO score 2.46 ± 1.19 vs. 2.10 ± 1.22; p < 0.001; PROGRESS CTO score 1.28 ± 0.89 vs. 0.91 ± 0.85; p < 0.001). Absence of CABG was associated with lower risk of technical and procedural failure (OR: 0.60, 95% CI: 0.43-0.85 and OR: 0.58, 95% CI: 0.40-0.83, respectively). No significant differences in the incidence of in-hospital MACCE (3.8% no-CABG vs. 4.4% prior-CABG; p = 0.766) were observed between groups. CONCLUSION: In a contemporary multicenter CTO-PCI registry from Latin America, prior-CABG patients had more comorbidities, higher anatomical complexity, lower success, and similar in-hospital adverse event rates compared with no-CABG patients.

RESUMO

RESUMEN Introducción: La diabetes mellitus (DM) se ha asociado a un incremento en los resultados adversos en pacientes tratados con angioplastia coronaria (ATC), en comparación con los pacientes no diabéticos. Objetivos: Evaluar el riesgo de eventos cardiovasculares mayores en los pacientes diabéticos, estratificados según el tratamiento recibido (no insulinorrequirientes o insulinorrequirientes), en una población de pacientes no seleccionada tratados con angioplastia coronaria. Material y métodos: Análisis de registro, unicéntrico y retrospectivo de pacientes con enfermedad coronaria tratados con ATC desde marzo 2009 a junio 2018, según la presencia de DM estratificada de acuerdo con el tratamiento establecido para el control del desorden metabólico en: DM insulino-requirientes (DM-IR) y DM no insulino-requirientes (DM-NIR). Se aplicó un modelo de regresión de Cox ajustado para evaluar la relación entre la presencia de diabetes y el riesgo de eventos cardiovasculares mayores. Resultados: Se incluyeron 6.313 pacientes (seguimiento promedio 4,1 ± 1,8 años), con una prevalencia global de DM del 22,8% (DM-NIR 19,1%; DM-IR 3,8%). Los pacientes diabéticos presentaron un perfil de riesgo elevado, particularmente los DM-IR. Al seguimiento promedio, el riesgo ajustado de eventos cardiovasculares mayores fue similar entre los pacientes No-DM y los DM-NIR (HR 1,02 [0,81-1,27], p 0,85). En relación con los pacientes DM-IR, se observó un riesgo elevado comparados con los No-DM (HR 1,73 [1,20-2,49], p 0,003) y con los DM-NIR (HR 1,65 [1,10-2,48], p 0,015). Se observó una interacción significativa entre el estado diabético y el riesgo de eventos según la indicación de la angioplastia coronaria al ingreso (pint 0,045). Conclusiones: En nuestra serie de pacientes tratados con angioplastia coronaria y con seguimiento a largo plazo, los pacientes diabéticos presentaron alto riesgo de eventos cardiovasculares mayores. Este riesgo se observó particularmente incrementado en pacientes DM-IR. Sin embargo, no se evidenciaron diferencias significativas en el riesgo de eventos entre los pacientes DM-NIR y los No-DM.


ABSTRACT Background: Diabetes mellitus (DM) has been associated with an increase in adverse outcomes in patients treated with coronary angioplasty, compared to non-diabetic patients. Objective: To evaluate the risk of major adverse cardiovascular events in diabetic patients, stratified according to the treatment (non-insulin dependent or insulin-dependent), in a population of unselected patients treated with coronary angioplasty. Methods: Registry-based analysis of patients with coronary artery disease undergoing percutaneous coronary intervention from March 2009 to June 2018, according presence of DM stratified according to the established treatment for the metabolic disorder: insulin-dependent DM (ID -DM) and non-insulin dependent DM (NID -DM). An adjusted Cox regression model was applied to evaluate the relationship between the diabetic status and the risk of major adverse cardiovascular events. Results: A total of 6313 patients were included (mean follow-up 4.1 ± 1.8 years), with a global prevalence of DM of 22,8% (non-insulin dependent DM 19,1%, insulin-dependent DM 3,8%). Diabetic patients showed a higher risk profile, particularly those with ID-DM. At the average follow-up, the adjusted risk of MACE was similar between Non-DM patients and the NIR-DM patients (HR 1,02 [0,81-1,27], p 0.85). In relation to DM-IR patients, it was observed a higher risk of MACE in comparison to Non-DM (HR 1,73 [1,20-2,49], p 0.003) and NIR-DM (HR 1,65 [1,10-2,48], p 0.015). A significant interaction was observed between the diabetic status and the risk of MACE according to the indication of the percutaneous coronary artery intervention (pint 0.045). Conclusions: In our registry of patients undergoing PCI, with long-term follow-up, DM patients had a higher risk of MACE. The risk of MACE was particularly increased in ID-DM patients. However, there were no significant differences in the risk of MACE between DM-NIR and non-DM patients.

RESUMO

RESUMEN Introducción: El acceso radial se ha asociado a numerosos beneficios en angioplastia coronaria en comparación con el acceso femoral. Sin embargo, múltiples registros internacionales han reportado una escasa adherencia a esta técnica. Objetivos: Evaluar la seguridad, la eficacia y la eficiencia operativa de la angioplastia coronaria según la vía de acceso utilizada y el cuadro clínico del paciente. Métodos: Análisis de registro, unicéntrico y retrospectivo de los pacientes con enfermedad coronaria tratados con angioplastia coronaria desde marzo de 2009 a junio de 2018, según el acceso vascular. Se aplicó un modelo de regresión de Cox ajustado para evaluar la relación entre la vía de acceso y el riesgo de eventos cardiovasculares mayores y un modelo de regresión logística para evaluar la relación con el sangrado mayor y las complicaciones del acceso vascular. La eficiencia operativa se evaluó mediante la medición del tiempo de internación total y los costos totales asociados a esta. Resultados: Se incluyeron 8155 angioplastias coronarias (seguimiento promedio 1448,6 ± 714,1 días), mediante acceso radial (n = 5706) o acceso femoral (n = 2449). A los 30 días, el riesgo de eventos cardiovasculares mayores se redujo significativamente con el acceso radial (HR 0,66 [0,5-0,88], p = 0,004), a expensas de una reducción de la mortalidad total. A su vez, el acceso radial redujo significativamente el riesgo de sangrado mayor (HR 0,33 [0,16- 0,67], p = 0,002) y de complicaciones del acceso vascular (HR 0,72 [0,53-0,98], p = 0,038). Se observó una interacción significativa entre la vía de acceso y el riesgo de eventos según el cuadro clínico al ingreso. Se observó una reducción significativa del tiempo total de internación (≈30%) y de sus costos totales (≈15%) mediante el uso del acceso radial. Conclusiones: El uso del acceso radial en angioplastia coronaria es seguro y eficaz en comparación con el acceso femoral, con menores tasas de eventos cardiovasculares mayores a los 30 días, como, así también, un menor riesgo de sangrado mayor y complicaciones del acceso vascular. Asimismo, el acceso radial se asoció con una mayor eficiencia operativa durante la internación.


ABSTRACT Background: Radial access has been associated with many advantages in percutaneous coronary intervention compared with femoral access. However, many international registries have reported poor adherence to this technique. Objectives: The aim of this study was to evaluate the safety, efficacy and operational efficiency of percutaneous coronary intervention according to the access site and the clinical presentation of the patient. Methods: A single-center, retrospective registry of patientis with coronary artery disease undergoing percutaneous coronary intervention was conducted from March 2009 to June 2018 according to the vascular access. A Cox proportional-hazards model was used to analyze the association between vascular access and risk of major cardiovascular eventis, and a logistic regression model was applied to assess the relationship between major bleeding and access site complications. Total hospital stay and total hospitalization costis were measured to evaluate the operational efficiency. Resultis: A total of 8,155 percutaneous coronary interventions (mean follow-up of 1,448.6±714.1 days), via radial access (n=5,706) or femoral access (n=2,449), were included in the study. At 30 days, the risk of major cardiovascular eventis was significantly lower with the radial access (HR 0.66 [0.5-0.88], p=0.004), at the expense of a reduction in all-cause mortal-ity In addition, radial access significantly reduced the risk of major bleeding (HR 0.33 [0.16-0.67], p=0.002) and access site complications (HR 0.72 [0.53-0.98], p=0.038). A significant interaction was observed between the vascular access site and the risk of eventis according to the clinical presentation at admission. Use of radial access was associated with a significant reduction in the length of total hospital stay (≈30%) and total hospitalization costis (≈15%). Conclusions: The use of radial access in percutaneous coronary intervention was safe and effective compared with the femoral access, with lower rates of major cardiovascular eventis at 30 days, lower risk of major bleeding and of access site complications. Moreover, radial access was associated with greater operational efficiency during hospitalization.

RESUMO

RESUMEN: Introducción: Actualmente no hay consenso sobre el manejo anestésico más adecuado en el implante valvular aórtico percutáneo por vía transfemoral. Aunque se ha demostrado la factibilidad de concretar el procedimiento bajo anestesia local con sedación consciente o sin esta, los resultados clínicos reportados son controvertidos. Objetivos: Evaluar la seguridad y eficacia del implante valvular aórtico percutáneo por vía transfemoral realizado bajo anestesia general versus anestesia local con sedación consciente. Material y métodos: Análisis unicéntrico y retrospectivo de los pacientes con estenosis aórtica grave sintomática con alto riesgo quirúrgico sometidos a un implante valvular aórtico percutáneo por vía transfemoral desde marzo de 2009 a diciembre de 2016, según el manejo anestésico. Los desenlaces de seguridad y eficacia fueron evaluados a 30 días según las definiciones del Valve Academic Research Consortium-2. Además, se evaluaron los principales tiempos durante la internación. Resultados: Se incluyeron 121 pacientes (Edad 83,2 ± 5,7 años, hombres 48,8%), tratados con un implante valvular aórtico percutáneo por vía transfemoral bajo anestesia general (n = 55, 45,5%) o anestesia local con sedación consciente (n = 66, 54,5%). No se observaron diferencias significativas en los resultados intraprocedimiento ni en los desenlaces de seguridad y eficacia a 30 días. La mortalidad a 30 días fue del 7,3% en el grupo AG y del 3% en el grupo anestesia local con sedación consciente 3%, p log-rank 0,28 (mortalidad global 5%). La necesidad de conversión a anestesia general se presentó en 2 pacientes (3%), por complicaciones vasculares mayores durante el procedimiento. El grupo anestesia local con sedación consciente presentó menor tiempo total de procedimiento, internación en unidad de cuidados intensivos e internación total. Conclusión: El implante valvular aórtico percutáneo por vía transfemoral realizado bajo anestesia local con sedación consciente, parece ser una alternativa segura y eficaz al uso de anestesia general.


Abstract: Background: Currently, there is no consensus about the most adequate anesthetic management in transfemoral transcatheter aortic valve replacement. Although it has been shown that local anesthesia (LA) with or without conscious sedation is feasible, clinical results are controversial. Objective: The aim of this study was to evaluate the safety and efficacy of transfemoral transcatheter aortic valve replacement performed under general anesthesia versus local anesthesia with conscious sedation. Methods: This was a single-center, retrospective study of high risk patients with severe aortic stenosis undergoing transfemoral transcatheter aortic valve replacement between March 2009 and December 2016. The population was divided according to anesthetic management. Safety and efficacy outcomes were evaluated at 30-days and were classified according to definitions of the Valve Academic Research Consortium-2. In addition, key times during hospitalization were evaluated. Results: A total of 121 patients undergoing transfemoral transcatheter aortic valve replacement under general anesthesia (n=55, 45.5%) or local anesthesia with conscious sedation (n=66, 54.5%). were included in this analysis. Mean age was 83.2±5.7 years and 48.8% were men. There were no differences in either the procedural result or in the 30-day efficacy and safety outcomes. The rate of death at 30-days was 7.3% in the group with general anesthesia and 3% in the local anesthesia with conscious sedation group (log-rank p 0.28). The need of conversion to general anesthesia was 3% (2 patients), in all cases due to major vascular complications during the procedure. In the local anesthesia with conscious sedation group shorter procedural time, intensive care unit and hospital length of stay were observed. Conclusions: Transfemoral transcatheter aortic valve replacement performed under local anesthesia with conscious sedation seems to be a safe and effective alternative to the use of general anesthesia.
