Percutaneous treatment of atrial septal defects, muscular ventricular septal defects and patent ductus arteriosus in infants under one year of age.
(5/221)
Amplatzer devices are used for the percutaneous closure of ostium secundum atrial septal defects, muscular ventricular septal defects and patent ductus arteriosus. However, very little experience has been gained in using these devices in infants under 1 year of age. Between January 2001 and January 2008, 22 symptomatic infants aged under 1 year underwent percutaneous treatment: three had an ostium secundum atrial septal defect, 15 had patent ductus arteriosus, and four had a muscular ventricular septal defect. All the procedures were completed successfully. No immediate or medium-term complications were observed. Closure of these types of defect using an Amplatzer device in infants under 1 year of age, who would otherwise require surgery, is a safe and effective procedure. (+info)
Post-traumatic ventricular septal defects--review of the literature and a novel technique for percutaneous closure.
(6/221)
Post-traumatic ventricular septal defect (VSD) is infrequent, with clinical sequelae ranging from imminent death to complete spontaneous resolution. The most appropriate management strategy is unclear. Careful observation has been advocated in the management of these patients. We demonstrate this concept by reporting two different approaches in two patients with traumatic injuries to the chest and review the English-language literature of both spontaneous and percutaneous closure of these lesions. In our case of percutaneous closure, we report a novel technique involving a transseptal approach that does not require exteriorization and formation of an arteriovenous loop, thus avoiding loop-related complications.
