ABSTRACT
Objetivo: Analizar la asociación entre mortalidad en cirugía de cardiopatías congénitas del adulto y los factores relacionados con el paciente y la intervención. Método: Estudio descriptivo de intervenciones por cirujanos con actividad habitual en cardiopatías congénitas (238), cardiopatías adquiridas (117) y residentes (108). Se evaluó la asociación de la mortalidad con el riesgo y complejidad quirúrgica, actividad habitual del cirujano, y tiempo de circulación extracorpórea y de pinzamiento aórtico, mediante modelos de regresión logística. Resultados: Se incluyeron 463 cirugías (442 con circulación extracorpórea) entre 1991 y 2012. Edad mediana de intervención: 34 años (52.8% mujeres); primera cirugía 295, reintervención 168. La puntuación mediana del Aristóteles fue 6.8, con complejidad significativamente mayor tras reestructurarse la Unidad en 2001. La mortalidad hospitalaria total fue del 3.9%. La mortalidad se asoció significativamente al número de intervenciones previas (OR: 5.02; IC 95%: 1.44-17.52), intervenciones por cirujanos de cardiopatía adquirida (OR: 3.53; IC 95%: 1.14-10.98), Aristóteles alto (OR: 1,64; IC 95%: 1.18-2.29), y tiempos prolongados de extracorpórea (OR: 1.13; IC 95%: 1.07-1.19). Conclusiones: La mortalidad en cirugía de cardiopatía congénita en adultos es baja. Las intervenciones de alta complejidad, tiempos elevados de extracorpórea y múltiples reintervenciones se asocian con mayor mortalidad. La participación de cirujanos especialistas en cardiopatías congénitas se asocia con mejores resultados.
Objective: To assess the association between mortality in surgery of congenital heart disease in adults, and factors related to patients and operations. Method: Descriptive study of operations performed by specialized surgeons in congenital heart surgery (238), adult acquired surgery (117), and specialty residents (108). The association of mortality with surgical risk and complexity, specialization of surgeon, cardiopulmonary by-pass and aortic cross clamping was assessed fitting logistic regression models. Results: A total of 463 operations were included (442 with cardiopulmonary by-pass) in the study performed between 1991 and 2012. Median age at surgery: 34; 52.8% were women. First surgery: 295, reoperation: 168. Median score of Aristotle was 6.8, with significantly higher complexity since 2001, after restructuring the Unit. Overall hospital mortality was 3.9%. Mortality was significantly associated to number of previous surgeries (OR: 5.02; 95%CI: 1.44-17.52), operations by acquired heart disease surgeons (OR: 3.53; 95%CI: 1.14-10.98), higher Aristotle (OR: 1,64; 95%CI: 1.18-2.29), and high cardiopulmonary by-pass time (OR: 1.13; 95%CI: 1.07-1.19). Conclusions: Surgery of congenital heart disease in adults has been performed with low mortality. High complexity interventions, prolonged cardiopulmonary by-pass times and multiple reoperations were associated to higher mortality. Participation of cardiac surgeons specialized in congenital heart disease is associated with better outcomes.
