Giant aortic aneurysm is defined as aneurysm in the aorta greater than 10 cm in diameter. It is a rare finding since most patients will present with complications of dissection or rupture before the size of aneurysm reaches that magnitude. Etiological factors include atherosclerosis, Marfan’s syndrome, giant cell arteritis, tuberculosis, syphilis, HIV-associated vasculitis, hereditary hemorrhagic telangiectasia, and medial agenesis. Once diagnosed, prompt surgical intervention is the treatment of choice. Although asymptomatic unruptured giant aortic aneurysm has been reported in the literature, there has not been any case of asymptomatic giant dissecting aortic aneurysm reported in the literature thus far. We present a case of a 62 year old man with a 14 cm of diameter aneurysm of the ascending aorta and aortic arch without impact on the aortic root.

Endocarditis isolated from the pulmonary valve is not that common. It has a clinical appearance of right heart endocarditis, with potential pulmonary septic emboli. We report a case of a 14-years-old girl treated for isolated pulmonary valve endocarditis and pulmonary stenosis in which the destruction of the pulmonary valve required the use of a pulmonary homograft for RVOT reconstruction.
