Through midterm follow-up, treatment of high-surgical-risk TAAA and AAA patients with the MFM appears to be safe and effective, maintaining branch vessel patency and reducing rupture risk through reduction of aneurysm diameter and modulation of flow dynamics. Longer term follow-up is needed.

Chylothorax is a possible complication of intrathoracic surgery. The diagnosis of postoperative chylothorax is easy; however, the treatment can cause problems of management because of the lack of consensus. In children, the most common causes of postoperative chylothorax are the cures for congenital heart diseases. We report the case of a two-year-old child, presenting with a chylothorax following surgery of the ductus arteriosus. Our case illustrates the treatment that must first include medical measures without delaying the surgery. The risk is the installation of nutritional and immune deficiency.

Aorto-mitral discontinuity is uncommun complication of infective endocarditis. In the reported case, images were produced using transthoracic echocardiograms and transesophageal echocardiograms. The latter revealed aorto-mitral discontinuity and a perforated aortic valve aneurysm of the anterior leaflet. These additional examinations may assist in the planning of surgical procedures usually including double valve replacement in addition to aortic root replacement/repair.
