Double Outlet Right Ventricle Infective Endocarditis: A Rare Combination and a Therapeutic Challenge

Infective endocarditis involving the right side of the heart occurs rarely and often involves the tricuspid valve. The isolated pulmonary valve infective endocarditis (IPVIE) is a less common condition that occurs in specific population. The double outlet right ventricle (DORV) is an unusual congenital heart disease. The association of DORV and IPVIE darkens the prognosis. We report two cases of the association of DORV and IPVIE. The transthoracic echocardiography (TTE) is the base to the diagnosis. Right sided infective endocarditis in the lack of a guided strategy remains a therapeutic challenge.
