Percutaneous transhepatic and transseptal dilatation of a surgically implanted Melody Valve in the mitral position in a 2-year-old child.

The use of the Melody (Medtronic, Minneapolis, MN, USA) biological prosthesis in mitral position has shown acceptable short-term results. Furthermore, it allows its expansion with a balloon when the patient grows up, and this procedure can be performed by a venous catheterization through transseptal approach through an interatrial communication or puncturing the septum. Patients with complex congenital heart disease undergoing multiple surgical and percutaneous interventions may present with vascular complications such as thrombosis of the femoral venous system that make percutaneous access impossible.

Pericardial agenesis.

Congenital pericardial defect is a rare and usually asymptomatic condition which is classified incomplete or partial. Up to 70% of cases consist of complete absence of left pericardium. The diagnosis may be challenging due to its low frequency and absence of correlation with any specific finding on the clinical examination.

Risk of coronary artery involvement in Kawasaki disease.

Introduction: Kawasaki disease refers to systemic vasculitis with risk of coronary artery disease. Our objective is to identify risk factors associated with coronary artery disease in patients with complete and incomplete Kawasaki disease.

Material And Methods: Descriptive, retrospective study conducted in patients diagnosed with Kawasaki disease in a tertiary-care hospital between 2008 and 2014.
