Congenital heart diseases account for 0.5-1% of births. The management of children with cardiac malformation requires treatment in a suitable center, adequate medical equipment and specific anesthetic and surgical knowledge.

This is a longitudinal, retrospective and descriptive study which takes place over a period from January 2017 to March 2020 (38 months) at the level of the thoracic and cardiovascular surgery clinic of the university Hospital Center of Fann in Dakar. All patients who underwent aortic valve replacement during this period were included in the study.

It is usually indicated for patients with complicated bubbles or when they are the underlying cause of disabling dyspnea. This study aims to determine the indications for bullectomy and to evaluate surgical outcomes in our Department.

By a geometric progression on an elliptic curve, we mean the existence of rational points on the curve whose -coordinate (or -coordinate) are in geometric progression. We find infinite families of twisted Edwards curves and Huff curves with geometric progressions of length 5, an infinite family of Weierstrass curves with 8 term progressions, as well as infinite families of quartic curves containing 10-term geometric progressions.
