RESUMO

Resumen Antecedentes: Los procedimientos coronarios invasivos conllevan la administración de contraste y la exposición a radiaciones ionizantes, comportando un incremento de la morbimortalidad. La angiografía coronaria rotacional (ACR) permite adquirir múltiples proyecciones con una inyección de contraste. Hasta la fecha, no hay metaanálisis específicos comparando la ACR y la angiografía coronaria convencional (ACC) en pacientes en los que se realizan procedimientos coronarios invasivos, tanto diagnósticos como diagnósticos y terapéuticos. El objetivo de este metaanálisis es evaluar el impacto de la ACR en la cantidad de contraste, y la radiación ionizante en procedimientos coronarios invasivos. Métodos: Se realizó una búsqueda en las bases de datos PubMed y Ovid para identificar estudios tanto diagnósticos como diagnósticos y terapéuticos que comparasen ACR y ACC. Los estudios fueron evaluados sobre la calidad y los sesgos, y fueron incluidos si contemplaban alguna de las siguientes variables de valoración: volumen de contraste, radiación ionizante medida como producto dosis-área, Kerma-aire o tiempo de fluoroscopia. Resultados: Dieciséis estudios, totalizando 2,327 pacientes, fueron incluidos en el análisis final (1,146 pacientes recibieron ACR y 1,181, ACC), objetivándose diferencias significativas en volumen de contraste (diferencia estándar de medias (intervalo de confianza al 95%) −1.887 (−2.472 a −1.302); p < 0.001), producto dosis-área (−0.726 (−1.034 a −0.418); p < 0.001), Kerma-aire (−0.842 (−1.104 a −0.581); p < 0.001) y tiempo de fluoroscopia (0.263 (−0.496 a −0.030); p = 0.027). Conclusiones: La ACR permite reducir el volumen de contraste y la radiación, evaluada como producto dosis-área, Kerma-aire y tiempo de fluoroscopia en pacientes a los que se les realizan procedimientos coronarios invasivos.


Abstract Background: Invasive coronary procedures involve the administration of iodinated contrast and the exposure to ionising radiations, increasing morbidity and mortality. The rotational coronary angiography (RCA) allows acquiring multiple projections with a unique injection of iodinated contrast. To date, there are no meta-analyses specifically comparing RCA and conventional coronary angiography (CCA) in patients undergoing invasive coronary procedures, whether diagnostic or diagnostic and therapeutic. The aim of this meta-analysis is to assess the impact of RCA on the amount of iodinated contrast and the exposure to ionising radiations during invasive coronary procedures. Methods: A search in PubMed and Ovid databases was conducted to identify studies, including diagnostic and diagnostic and therapeutic studies, comparing RCA and CCA. The manuscripts were evaluated on quality and biases, and were included if they analysed any of the following endpoints: volume of contrast and exposure to ionising radiations measured as dose-area product, and Kerma-air or fluoroscopy time. Results: Sixteen studies, with a total of 2,327 patients, were included in the final analysis (1,146 patients underwent RCA and 1,181 patients underwent CCA), with significant differences being detected in volume of contrast (standard difference in means (95% confidence interval) −1.887 (−2.472 to −1.302); P < .001), dose-area product (−0.726 (−1.034 to −0.418); P < .001), Kerma-air (−0.842 (−1.104 to −0.581); P < .001), and fluoroscopy time (0.263 (−0.496 to −0.030); P = .027). Conclusions: RCA reduces the volume of contrast and the exposure to radiation, evaluated as dose-area product, Kerma-air, and fluoroscopy time, in patients undergoing invasive coronary procedures.

RESUMO

Pulmonary vein isolation is an effective treatment for patients with symptomatic paroxysmal atrial fibrillation. Cryoablation balloon therapy has been developed as an alternative. Cryoablation complications have primarily been related to phrenic nerve palsy, vascular complications, stroke, and others of lesser incidence. Esophageal lesions are rare and they are not yet completely understood.

RESUMO

Introducción: Los pacientes con cáncer pueden constituir un especial grupo de riesgo para el desarrollo de endocarditis infecciosa (EI) debido a que frecuentemente están sometidos a maniobras invasivas. Nuestro objetivo es conocer cuál es el perfil diferencial y el pronóstico de los pacientes con EI y cáncer. Métodos: Estudio observacional retrospectivo de todos los pacientes con EI diagnosticados consecutivamente en un hospital entre 2005 y 2015. Se realiza un análisis comparativo entre los pacientes con enfermedad oncológica y sin ella, así como un seguimiento a largo plazo. Resultados: Se diagnosticaron 208 casos de EI, de los cuales 32 sufrían enfermedad oncológica. No hubo diferencias significativas en cuanto a la edad (67,5 [59,2-74] vs. 64 [51-74] años), y la comorbilidad estimada por el índice de Charlson fue similar cuando no se consideró el propio diagnóstico de cáncer (4 [2,2-5] vs. 3,9 [2-5]). Se relacionó principalmente con la asistencia sanitaria (59,5% vs. 24,4%, p<0,001), predominó Staphylococcus aureus como agente causal (35%) y la localización tricuspídea fue 3 veces más frecuente (18,8% vs. 6,2%). Un 18,7% de pacientes no se intervinieron quirúrgicamente a pesar de tener indicación, frente al 7,4% de pacientes sin cáncer. La mortalidad intrahospitalaria alcanzó el 45,5% en pacientes con cáncer y la probabilidad de supervivencia al año fue del 40%. Conclusiones: La EI en pacientes con cáncer está predominantemente causada por estafilococos y presenta una elevada mortalidad precoz. A pesar de que se relaciona frecuentemente con la asistencia sanitaria, los pacientes se ven limitados desde el punto de vista terapéutico (AU)


Introduction: Cancer patients may constitute a special risk group for the development of infective endocarditis (IE) because they are often subjected to invasive procedures. The aim of this study is to determine the differential clinical profile and prognosis of patients with IE and cancer. Methods: A retrospective observational study was conducted on all patients consecutively diagnosed with IE in a single centre between 2005 and 2015. A comparative analysis was performed between patients with cancer and those free of disease, as well as a long-term follow-up. Results: There were 208 IE cases, of which 32 had a cancer diagnosis. There were no significant differences in age (67.5 [59.2-74] vs. 64 [51-74] years). The Charlson comorbidity index was same whether cancer was diagnosed or not (4 [2.2-5] vs. 3.9 [2-5]). IE in cancer patients was mainly associated with health care (59.5% vs 24.4%, P<.001). Staphylococcus aureus was the main causative agent (35%), and the tricuspid location was three times more common (18.8% vs. 6.2%). Surgery was not performed in 18.7% of patients, despite having an indication, compared with 7.4% of patients without cancer. In-hospital mortality for cancer patients was 45.5%, and the probability of survival at one year was 40%. Conclusions: IE in patients with cancer is predominantly caused by staphylococci, and has high early mortality. Although it is often related to health care, patients are limited from the therapeutic point of view (AU)

RESUMO

Secondary or metastatic cardiac tumors are about 20-40 times more common than primary benign or malignant cardiac tumors. Cardiac metastases are more frequent in carcinomas, they usually appear in patients over 50 years and the involvement by gender is similar. Any tumor can cause cardiac or pericardial metastasis, although isolated or combined tumor invasion of the pericardium is more common. Transthoracic echocardiography (TTE) is the primary diagnostic procedure, followed by computed tomography (CT) and cardiac magnetic resonance imaging (MRI) to verify positive findings and to analyze other structures of the mediastinum and chest. Treatment of such tumors is generally associated with poor results and unfavorable prognosis. We report the case of an unusual cardiac metastasis.
