Characteristics of pediatric patients operated of aortic coarctation in the years 2009-2018 at the National Institute of Cardiology Ignacio Chávez

Abstract

Objective: The objective of the study was to determine the radiographic, electrocardiographic, angiographic, and surgical characteristics of the patients operated with aortic coarctation at the Ignacio Chavez National Institute of Cardiology between 2009 and 2018. Methods: The variables considered relevant for the study were collected from the electronic file, recorded in the previously designed Excel capture sheet. Various radiographic, electrocardiographic, angiographic, and surgical variables were analyzed. Post-surgical clinical evolution, complications, and requirements for interventional or surgical procedures were assessed, and the response to these as well as the different outcomes was assessed. Results: A total of 187 patient surgeries are reported from 2 days of age to 12 years, where the radiological, electrocardiographic characteristics, and presentation age are mentioned. The total number of deaths in the 9 years was 17 cases, which were mostly (94%) before the 1 st year of life. The most commonly used surgical technique (90%) was extended coarctectomy with term-terminal anastomosis. The recorded post-operative complications were in descending order: ventricular failure, systemic arterial hypertension, renal failure that required peritoneal dialysis, etc. Conclusions: The registered population that required surgical intervention at the National Institute of Cardiology was mostly a minor infant with a median of 3 months in their surgery age. In view of the surgical technique used, the one that had better results and that did not show a significant association with the number of deaths was the extended coarctectomy with end-to-end anastomosis.

“…1). 7 About 75% of CoA cases are associated with coexistent bicuspid aortic valve (BAV), thus routine screening and arch imaging are recommended. 5,6 Intervention indications include: 1) visualized significant collateral flow; 2) CoA attributed hypertension and heart failure; and 3) CoA pressure gradient ≥20 mmHg.…”
