Valoración de la función sistólica del ventrículo derecho para la toma de decisiones en paciente intervenida de corrección de atresia pulmonar con comunicación interventricular y colaterales aortopulmonares

The prognosis of complex adult congenital heart disease has improved with the development of new imaging techniques for diagnosis and early treatment. The assessment of right ventricular systolic function with the new echo techniques has made important advances. The following case illustrates the importance of new techniques in the assessment of right systolic function after cardiac surgery.El pronóstico de las cardiopatías congénitas complejas del adulto ha mejorado con el desarrollo de las nuevas técnicas de imagen para el diagnóstico oportuno y tratamiento temprano. Asimismo, la valoración de la función sistólica del ventrículo derecho ha tenido importantes avances. El siguiente caso ilustra la importancia de las nuevas técnicas en la valoración de la función sistólica derecha tras la cirugía de un paciente con una cardiopatía congénita compleja

Análisis de mortalidad y estancia hospitalaria en cirugía cardiaca en México 2015: datos del Instituto Nacional de Cardiología

Resumen: Objetivo: Analizar las causas de mortalidad hospitalaria de pacientes operados de cirugía cardiaca en México en el año 2015. Identificar los factores de riesgo de mortalidad y realizar una correlación con el tiempo de estancia hospitalaria en terapia intensiva cardiovascular. Método: Estudio de casos y controles. Se estudió la base de datos de la Terapia Intensiva Cardiovascular del Instituto Nacional de Cardiología. Se incluyeron todos los pacientes adultos operados de cirugía cardiaca en el año 2015. Resultados: Se operaron 571 pacientes. La indicación quirúrgica predominante fue la cirugía de cambio valvular único o múltiple, seguida de la cirugía de revascularización coronaria y corrección de cardiopatías congénitas del adulto. La mortalidad global fue de un 9.2% y el 8% falleció en terapia intensiva. Los principales factores de riesgo de muerte fueron la presencia de falla orgánica o hipertensión pulmonar prequirúrgica, y el tiempo prolongado de circulación extracorpórea. La principal causa de muerte fue el choque cardiogénico. La mortalidad hospitalaria observada en esta población fue mayor para los operados de tromboendarterectomía pulmonar, cirugía de enfermedad aórtica compleja y cirugía valvular. Conclusiones: La mortalidad de los pacientes operados de cirugía cardiaca en México difiere levemente de la reportada en la literatura mundial porque se trata mayormente de cirugía multivalvular y de procedimientos quirúrgicos mixtos complejos. Abstract: Objective: To analyse hospital mortality in patients subjected to cardiac surgery in Mexico during the year 2015, and identify the mortality risks factors, and its correlation with days of hospital stay in the cardiovascular intensive care unit. Method: The database of Cardiovascular Intensive Care of the National Institute of Cardiology was examined for this cases and controls study that included only adult patients subjected to cardiac surgery during the year 2015. Results: A total of 571 patients were subjected to a surgical procedure. The predominant indication was single or multiple valve replacement surgery, followed by coronary revascularisation surgery, and correction of adult congenital heart disease. Overall mortality was 9.2, and 8% died in intensive care. The main risk factors for death were preoperative organ failure or pulmonary hypertension, and prolonged time with extracorporeal circulation. The primary cause of death was secondary to cardiogenic shock. The hospital mortality observed in this population was higher for patients undergoing pulmonary thromboendarterectomy, complex aortic disease surgery, and valvular surgery. Conclusions: The mortality of patients undergoing cardiac surgery in Mexico differs slightly from that reported in the world literature, primarily because there were more multivalvular surgeries and mixed complex procedures performed.

Usefulness of Easy-to-Use Risk Scoring Systems Rated in the Emergency Department to Predict Major Adverse Outcomes in Hospitalized COVID-19 Patients

Background: Several easy-to-use risk scoring systems have been built to identify patients at risk of developing complications associated with COVID-19. However, information about the ability of each score to early predict major adverse outcomes during hospitalization of severe COVID-19 patients is still scarce. Methods: Eight risk scoring systems were rated upon arrival at the Emergency Department, and the occurrence of thrombosis, need for mechanical ventilation, death, and a composite that included all major adverse outcomes were assessed during the hospital stay. The clinical performance of each risk scoring system was evaluated to predict each major outcome. Finally, the diagnostic characteristics of the risk scoring system that showed the best performance for each major outcome were obtained. Results: One hundred and fifty-seven adult patients (55 ± 12 years, 66% men) were assessed at admission to the Emergency Department and included in the study. A total of 96 patients (61%) had at least one major outcome during hospitalization; 32 had thrombosis (20%), 80 required mechanical ventilation (50%), and 52 eventually died (33%). Of all the scores, Obesity and Diabetes (based on a history of comorbid conditions) showed the best performance for predicting mechanical ventilation (area under the ROC curve (AUC), 0.96; positive likelihood ratio (LR+), 23.7), death (AUC, 0.86; LR+, 4.6), and the composite outcome (AUC, 0.89; LR+, 15.6). Meanwhile, the inflammation-based risk scoring system (including leukocyte count, albumin, and C-reactive protein levels) was the best at predicting thrombosis (AUC, 0.63; LR+, 2.0). Conclusions: Both the Obesity and Diabetes score and the inflammation-based risk scoring system appeared to be efficient enough to be integrated into the evaluation of COVID-19 patients upon arrival at the Emergency Department
