RESUMO
A 70-year-old man with an ascending aortic aneurysm was referred to our hospital. He had not shown any head symptoms and blood tests did not indicate any inflammation. Ascending aortic replacement was performed under cardiopulmonary bypass. Pathologic examination of the aneurysm wall was diagnosed for giant cell arteritis( GCA). Aortic aneurysm due to GCA without no symptom was extremely rare.

We report a case of a 15 month-old boy who underwent the arterial switch operation using cryopreserved aortic homograft for transposition of the great arteries with pulmonary regurgitation, with coexisting right ventricular outflow tract obstruction precluding atrial switch operation. Follow-up echocardiography at 6 months showed trivial neoaortic valve regurgitation, no significant systemic outflow obstruction, with good cardiac function. In small children, the choice of material for left ventricular outflow tract reconstruction is one of the most crucial issues. Cryopreserved homograft has been one of the primary options for the aortic valve replacement in small children because of the ease of suturing and excellent hemostasis.

A 6 month-old male infant (weight: 4.5 kg) with congenital aortic stenosis underwent aortic valve replacement with a pulmonary autograft (Ross procedure). The right ventricular outflow tract (RVOT) was reconstructed with a polytetrafluoroethylene (PTFE) -valved equine pericardial conduit. At the age of 5, re-RVOT reconstruction with an equine pericardial patch bearing a PTFE monocusp was required because of severe pulmonary stenosis resistant to 2 attempts of percutaneous transluminal pulmonary valvotomy. Currently, at the age of 8, the degree of aortic regurgitation is trivial and the pulmonary autograft is free of functional deterioration despite somatic growth.
