dc.descriptionIntroducción y objetivos: El conocimiento de la anatomía de las venas pulmonares y de la aurícula izquierda es fundamental para la planeación y prevención de posibles complicaciones durante la ablación de las venas pulmonares, procedimiento realizado para el manejo de la fibrilación auricular. Este estudio pretende caracterizar la anatomía (tamaño y forma) de las venas pulmonares y determinar las variantes anatómicas más comunes de las mismas. Métodos: Se analizaron 277 estudios de angioresonancia tridimensional y tomografía computarizada realizados previo al procedimiento de aislamiento de venas pulmonares. Se evaluaron los diámetros de la aurícula izquierda, de los ostia de las venas pulmonares y se determinaron la presencia de venas pulmonares comunes, accesorias y ramificaciones tempranas. Resultados: 75% de nuestros pacientes presentaron la anatomía normal de dos venas pulmonares derechas y dos izquierdas. En un 10,1% de los casos se encontraron venas supernumerarias y en un 11,2% se encontró un tronco común. En un 61% de los pacientes se encontraron ramas ostiales, las cuales en un 39,4% de los casos se presentaron en la vena pulmonar inferior derecha. Conclusiones: La evaluación de la morfología de la aurícula derecha y las venas pulmonares por medio de angioresonancia o tomografía computarizada, es necesaria para la realización de ablación por radiofrecuencia dada la alta frecuencia de variantes anatómicas y presencia de ramas ostiales.
dc.description.abstractIntroduction and objectives: Knowledge of the anatomy of the pulmonary veins and the left atrium is essential for planning and prevention of potential complications during pulmonary vein ablation procedure. This study aims to characterize the anatomy (size and shape) of the pulmonary veins and determine the most common anatomical variants thereof. Methods: 277 three-dimensional magnetic resonance angiography studies or computed tomography performed before the procedure of pulmonary vein isolation were analyzed. The diameters of the left atrium, the pulmonary vein ostia were assessed and the presence of common and early accessory pulmonary veins branching determined. Results: 75% of our patients had the normal anatomy of two right pulmonary veins and two lefts. In 10.1% of cases were found supernumerary veins and 11.2% found a common trunk. In 61% of patients were found ostial branches, which in 39.4% of cases were in the right inferior pulmonary vein. Conclusions: The evaluation of the morphology of the right atrium and pulmonary veins using magnetic resonance angiography or CT scan is necessary to perform radiofrequency ablation given the high frequency of anatomical variations and the presence of ostial branches.
