Elective implantation of covered stents for coarctation and recoarctation in adolescents and adults.

Introduction And Objectives: Stent implantation is an effective therapy for aortic coarctation and recoarctation. However, in adolescents and adults, aortic wall rupture and dissection can occur, as well as aneurysms during follow-up. In order to reduce these complications, we electively implant covered stents.

Stent-graft deployment for aortic rupture after stenting for aortic recoarctation.

We present the case of a 62-year-old woman who presented with recoarctation and then experienced rupture of the aorta and severe clinical deterioration after a stent was deployed. She was treated immediately by intrastent deployment of a stent-graft, which resolved the extremely serious situation.

[Pulmonary atresia with intact ventricular septum. Perforation and pulmonary valvuloplasty using a modified mechanical technique. Medium-term follow-up].

Introduction And Objectives: In patients with pulmonary atresia with intact ventricular septum (PAIVS), radiofrequency-assisted perforation of the valve is the most widely used initial therapy when the anatomy is favorable. We report our experience with a modified mechanical technique that gave good results.

Methods: Between November 2001 and October 2006, valve opening was carried out successfully in 11 consecutive neonates with a favorable anatomy (i.
