Frecuentación y motivos de asistencia en el servicio de urgencias tras la ablación de fibrilación auricular con criobalón / Emergency department attendance and reasons for consultation after cryoballoon ablation for pulmonary vein isolation of atrial fibrillation

Introducción y objetivos Existe poca información sobre la frecuentación a urgencias en las semanas siguientes a un procedimiento de aislamiento de venas pulmonares con criobalón. El objetivo del estudio es cuantificar las visitas a urgencias en los primeros 3 meses tras el procedimiento, evaluando los motivos, el diagnóstico final y la actitud terapéutica. Métodos Estudio observacional retrospectivo sobre 330 pacientes sometidos a un primer procedimiento de crioablación de fibrilación auricular. Se realizó un seguimiento de 90 días tras el procedimiento durante el que se registraron las visitas a urgencias con los síntomas que motivaron la consulta, electrocardiograma, actitud terapéutica y diagnóstico final, clasificado como alteración del ritmo, complicación confirmada, complicación posible y sin relación con el procedimiento ni con el trastorno arrítmico. Resultados Un total de 112 pacientes (34%) consultaron en urgencias, 50 de ellos (44,6%) por palpitaciones. En 44 pacientes (39,3%) se documentó una arritmia auricular sostenida. De las 29 consultas (25,9%) por síntomas potencialmente relacionados con complicaciones del procedimiento, 5 fueron complicaciones confirmadas de la punción inguinal, 10 quedaron con diagnóstico no confirmado de posible complicación y 41 visitas no guardaron relación con el procedimiento. El 21,4% del total de consultas fueron por palpitaciones en las que no se tomó ninguna medida terapéutica. Conclusiones Un tercio de los pacientes consultaron en urgencias al menos 1 vez, y los síntomas arrítmicos fueron el motivo más frecuente. Las complicaciones diferidas del procedimiento son raras y, en general, benignas. La disponibilidad de un sistema de teleconsulta con transmisión del ECG a distancia podría evitar hasta un 20% de los desplazamientos a urgencias. (AU)

Introduction and objectives There are few data on emergency visits after cryoballoon-based pulmonary vein isolation. The aim of this study was to quantify emergency department visits during the first 3 months after the procedure and to identify the reasons for consultation, final diagnoses, and the therapeutic approach. Methods Observational, retrospective study of 330 consecutive patients undergoing a first cryoballoon-based ablation procedure. Patients were followed up for 90 days after the procedure. We recorded emergency visits, symptoms, electrocardiographic data, and the therapeutic approach. Final diagnoses were classified as rhythm disorder, confirmed complication, possible complication, and unrelated to the procedure or to the arrhythmic disorder. Results A total of 112 (34%) patients attended the emergency department, 50 (44.6%) for palpitations. Sustained atrial arrhythmias were documented in 44 (39.3%) patients. Among the 29 (25.9%) visits for complications potentially related to the procedure, 5 were confirmed inguinal puncture complications and 10 were classified as unconfirmed possible complications. Forty-one visits were unrelated to the procedure or to the arrhythmic disorder. A total of 21.4% of the visits were due to palpitations requiring no therapeutic action. Conclusions A third of the patients attended the emergency department at least once, with the most frequent reason being arrhythmia-related symptoms. Late complications were rare and generally mild. Up to 20% of emergency visits could potentially be avoided by the availability of a teleconsulting system with remote electrocardiogram transmission. (AU)

Resultados en España de la encuesta de la Sociedad Europea de Cardiología sobre terapia de resincronización cardiaca (CRT-Survey II) / Spanish results of the Second European Cardiac resynchronization therapy survey (CRT-Survey II)

Introducción y objetivos: Se describen los resultados en España de la segunda encuesta de la Sociedad Europea de Cardiología sobre terapia de resincronización cardiaca (CRT-Survey II) y se comparan con los de los demás países participantes. Métodos: Pacientes a los que se implantó un dispositivo de terapia de resincronización cardiaca entre octubre de 2015 y diciembre de 2016 en 36 centros participantes. Se recogieron datos sobre las características basales de los pacientes y del implante, y un seguimiento a corto plazo hasta el alta hospitalaria. Resultados: La tasa de éxito del implante fue del 95,9%. La mediana [intervalo intercuartílico] de implantes anuales/centro en España fue significativamente menor que en los demás países participantes: 30 [21-50] frente a 55 [33-100] implantes/año (p=0,00003). En los centros españoles hubo una menor proporción de pacientes de edad ≥ 75 años (el 27,9 frente al 32,4%; p=0,0071), una mayor proporción de pacientes en clase funcional II de la New York Heart Association (el 46,9 frente al 36,9%; p <0,00001) y un mayor porcentaje de pacientes con criterios electrocardiográficos de bloqueo de rama izquierda (el 82,9 frente al 74,6%; p <0,00001). La media de la estancia hospitalaria fue menor en los centros españoles (5,8+/-8,5 frente a 6,4+/-11,6; p <0,00001) y una mayor proporción de pacientes recibieron un cable de ventrículo izquierdo cuadripolar (el 74 frente al 56%; p <0,00001) y fueron seguidos a distancia (el 55,8 frente al 27,7%; p <0,00001). Conclusiones: La encuesta CRT-Survey II muestra que en España hay una menor proporción de pacientes de 75 o más años que reciben un dispositivo de terapia de resincronización cardiaca, una mayor proporción de pacientes en clase funcional II de la New York Heart Association, con bloqueo completo de la rama izquierda del haz de His y con seguimiento a distancia, con estancias hospitalarias significativamente menores

Introduction and objectives: We describe the results for Spain of the Second European Cardiac Resynchronization Therapy Survey (CRT-Survey II) and compare them with those of the other participating countries. Methods: We included patients undergoing CRT device implantation between October 2015 and December 2016 in 36 participating Spanish centers. We registered the patients' baseline characteristics, implant procedure data, and short-term follow-up information until hospital discharge. Results: Implant success was achieved in 95.9%. The median [interquartile range] annual implantation rate by center was significantly lower in Spain than in the other participating countries: 30 implants/y [21-50] vs 55 implants/y [33-100]; P=.00003. In Spanish centers, there was a lower proportion of patients ≥ 75 years (27.9% vs 32.4%; P=.0071), a higher proportion in NYHA class II (46.9% vs 36.9%, P <.00001), and a higher percentage with electrocardiographic criteria of left bundle branch block (82.9% vs 74.6%; P <.00001). The mean length of hospital stay was significantly lower in Spanish centers (5.8+/-8.5 days vs 6.4+/-11.6; P <.00001). Spanish patients were more likely to receive a quadripolar LV lead (74% vs 56%, P <.00001) and to be followed up by remote monitoring (55.8% vs 27.7%; P <.00001). Conclusions: The CRT-Survey II shows that, compared with other participating countries, fewer patients in Spain aged ≥ 75 years received a CRT device, while more patients were in New York Heart Association functional class II and had left bundle branch block. In addition, the length of hospital stay was shorter, and there was greater use of quadripolar LV leads and remote CRT monitoring

Medium- and long-term outcome after a single second-generation cryoballoon ablation in patients with paroxysmal and persistent atrial fibrillation.

INTRODUCTION AND OBJECTIVES: To report medium- and long-term results following a single second-generation cryoballoon (CB2)-based ablation procedure in patients with paroxysmal (PAF) and persistent (PeAF) atrial fibrillation. METHODS: A retrospective study was performed of consecutive patients undergoing a first CB2-based ablation procedure in a tertiary center. Cryoenergy was applied for 3 min if a time to effect <60 s was documented or 4 min otherwise, with a bonus application in cases of late isolation or suboptimal temperature. Follow-up was obtained from the regional health electronic records system and by telephone or personal interviews. Recurrence was defined as any atrial arrhythmia >30 s beyond a three-month blanking period. The clinical impact of recurrences was classified using a severity score. RESULTS: A total of 172 patients (134 PAF and 38 PeAF) were included, of whom 25 (14.5%) had structural heart disease and 120 (69.7%) had a normal or mildly dilated left atrium. Acute success was achieved in 167 (97.1%). After a median follow-up of 27 (14-41) months, 100 patients (58.1%) remained free of atrial arrhythmias (64.2% for PAF and 36.8% for PeAF, p=0.006). Left atrial size (p=0.05) and clinical presentation as PeAF (p=0.006) were predictors of recurrence. Of patients with recurrences, 11.1% did not require further therapies and an additional 16.7% had good control with antiarrhythmic drugs. CONCLUSIONS: A single CB2 procedure resulted in 58.1% of patients remaining free of atrial arrhythmias at 27-month follow-up. Conservative management was useful in 27.8% of patients with recurrences.

Tetralogía de fallot en el adulto complicada con hemoptisis grave. Tratamiento mediante embolización de la arteria tirocervical izquierda / Fallot Tetralogy Complicated with Severe Hemoptysis in the Adult

La tetralogía de Fallot con atresia pulmonar constituye una situación especial en la que se permite la supervivencia hasta la edad adulta. En estos casos se desarrollan complicaciones, como la hemoptisis, que comprometen la vida del paciente y tienen difícil tratamiento. Cuando la causa del sangrado es la rotura de cortocircuitos arteriovenosos, frecuentes en las malformaciones vasculares múltiples que se originan en esta cardiopatía, la embolización selectiva de estas malformaciones puede ser una opción eficaz de tratamiento (AU)
