The ductus arteriosus, an essential fetal structure, normally closes spontaneously soon after birth. Its persistence into late adulthood is considered to be rare; infective endarteritis (IE) complicating a patent ductus arteriosus (PDA) is an even rarer event. The clinical picture of an infected PDA could be subtle, and the diagnosis is frequently delayed. We present the case of a young woman who presented with prolonged fever for whom we made the diagnosis of a PDA complicated by IE, with vegetations in both pulmonary and aortic walls with mycotic aneurysms of the descending aorta. She underwent surgery and the post-operative course was uneventful. To our knowledge, this is the first reported case of a PDA complicated with both pulmonary and aortic endarteritis.

A 4 year-old male presented with effort dyspnea, and was diagnosed as atrioventricular canal defects. This finding was confirmed by open heart surgery, and a congenital double orifice mitral valve was discovered. The septal defect was closed but the double orifice mitral valve was respected because of the absence of hemodynamic disturbance. We report this case with review of literature.

Traumatic tricuspid insufficiency is very rare. In this report we describe an interesting case of a 13-year-old boy who suffered chest trauma from a horse kick. Echocardiography demonstrated a remarkable tricuspid regurgitation with ventricular septal defect. Once assessing the diagnosis, an emergency open heart surgery was necessary to repair the injuries with good results.
