Management of right ventricular outflow tract with percutaneous Melody valve implantation in pediatric patients: experience in a high complexity center in Colombia.

Background: Congenital heart disease poses a therapeutic challenge, specifically pulmonary valve stenosis. This has been treated for many years with invasive procedures and bioprostheses, which over time, become dysfunctional due to the accumulation of fibrous tissue and calcification.

Objective: The aim of this study is to describe the use of endovascular management in the right ventricular outflow tract, as the beginning of an ongoing effot to improve pediatric outcomes in developing countries.

Intramural course of an anomalous left coronary artery is not always associated with a slit-like ostium.

Anomalous aortic origin of the left coronary artery from an incorrect aortic sinus has been reported as the second most common causes of sudden cardiac arrest in young athletes. Intramural course of the proximal left coronary artery is considered a high-risk morphology. It is associated with a slit-like ostium and elliptical shape of the proximal artery.

Congenitally corrected transposition of great arteries associated with interrupted aortic arch type A: a case report of an unusual association.

In this article, we report the third case, to our knowledge, of a congenitally corrected transposition of the great arteries associated with an interrupted aortic arch. This is a more complex and rare presentation than dextro-transposition of great arteries with interrupted aortic arch. The child ultimately succumbed to sepsis before the surgical repair was possible.
