RESUMEN
BACKGROUND: A fistulous tract in the mitro-aortic intervalvular fibrosa (MAIVF) is a rare entity, which presents as a complication of endocarditis or surgical trauma. Generally, it is associated to a pseudoaneurysm of the MAIVF (p-MAIVF) or aortic abscesses. MAIVF fistulas could potentially lead to devastating complications and a high mortality rate. This condition is managed surgically, either by a percutaneous closure or an open surgical approach. Herein we report the complex case of a patient with a MAIVF fistula secondary to bacterial endocarditis. Further clinical deterioration was caused by severe aortic valve insufficiency and hemodynamic compromise, requiring surgical intervention. CASE PRESENTATION: A 74-year-old male patient was admitted to a primary care center with complaints of malaise, asthenia, adynamia, hyporexia, and lower limb edema over the past eight days. His past medical history is positive for arterial hypertension and being monorenal. A transesophageal echocardiogram (TEE) was performed, exhibiting a 56% left ventricle ejection fraction (LVEF) and complicated aortic valve endocarditis. Surgical management through an open approach included vegetation resection, valve replacement, and closure of the MAIVF fistula. After completing antibiotic therapy, the patient was discharged without complications. During postoperative follow-up, the patient remained asymptomatic, and the control echocardiogram showed no signs of MAIVF fistula.4. CONCLUSIONS: The clinical case of a patient with a MAIVF fistula secondary to endocarditis by Streptococcus Anginous was presented. The fistulous tract was not associated to p-MAIVF or aortic abscess, findings which further deteriorate the patient's condition and increase the likelihood of fatality. This case reinforces the importance of a prompt diagnosis through cardiac imaging and timely surgical closure of the defect.

Resumen Introducción: La cardiopatía isquémica es un problema de salud pública y puede tratarse por medio de la revascularización miocárdica. Objetivo: Estructurar el primer perfil epidemiológico y clínico de los pacientes intervenidos en Tolima. Materiales y método: Es un estudio de corte transversal, de 183 pacientes mayores de 18 años programados para revascularización miocárdica entre septiembre de 2018 y septiembre de 2019. Se eligieron variables clínicas y demográficas. Se realizó un análisis descriptivo, un análisis bivariado para mortalidad y circulación extracorpórea, y una regresión logística para la mortalidad intrahospitalaria. Resultados: La edad media de los pacientes fue de 66.7 años y un 68.85% correspondió a la población femenina. Se presentó HA en 80.33%, tabaquismo en 49.18%, dislipidemia en 44.81% y DM en 40.98%. Se registró mayor proporción de complicaciones en los pacientes intervenidos sin CEC, como complicaciones pulmonares, FA de novo y una estancia intrahospitalaria y posoperatoria mayor. Los pacientes que fallecieron tuvieron mayor proporción de complicaciones, mayor estancia hospitalaria, mayor cantidad de reintervenciones y tiempo de ventilación mecánica. El modelo de regresión reveló una relación con mortalidad para los pacientes que tuvieron requerimiento de diálisis (OR = 8.7) complicaciones pulmonares (OR = 10.5) y desarrollo de FA de novo (OR = 11.3). Conclusiones: Este estudio caracteriza a la población para generar marcos de referencia en un grupo poco estudiado como el tolimense. De modo adicional, se presentaron mejores desenlaces en los pacientes llevados a revascularización miocárdica con circulación extracorpórea, y unas relaciones claras de mortalidad y complicaciones posoperatorias.
Abstract Introduction: The ischemic cardiopathy is a public health issue, that can be treated with a coronary artery bypass grafting (CABG). Objective: To present the first clinical and epidemiological profile of CABG treated patients in Tolima, Colombia. Materials and method: We conduct a cross sectional study, including 183 patients driven to a CABG procedure, between September 2018-2019. We chose clinical and demographic variables. And posteriorly, performed a descriptive and bivariate analysis, including mortality and extracorporeal circulation. Besides, we completed a logistic regression for intrahospital mortality. Results: The average age of our patients was 66,7 years, and 68.85% were female. They presented in an 80.33% arterial hypertension, smoked an 49.18%, had dyslipidemia and diabetes 44.81% and 40.95% respectively. There were more complications in patients who were drove into on pump CABG, primarily pulmonary complications, atrial fibrillation, mayor intrahospital and post-operatory stay. The patients who died, present more complications, intrahospital stay, reinterventions and mechanic ventilation time. Our regression model evidenced mortality association with post-operatory dialysis (OR = 8.7), pulmonary complications (OR = 10.5) and new atrial fibrillation (OR = 11.3). Conclusions: This study aim to characterize the Tolima's population, creating a reference in this less studied population. On the other side, the study discuss the better outcomes in patients taken to myocardial bypass with extracorporeal membrane oxygenation. And the association between dead and certain postoperative complications.
