Tratamiento percutáneo de los aneurismas del septo interauricular

Among a total number of 203 patients with atrial septal defects (ASD) or patent foramen ovale (PFO) who were treated by percutaneous closure, we selected 29 (19 with ASD and 10 with PFO) who fulfilled the criteria for atrial septal aneurysm. Eight patients had functional class II or III dyspnea, and 12 had a history of previous cerebrovascular accident (38%). Seven of the patients with ASD, had a single defect and 12 had multiple defects; 14 received a single occluder and 5 patients needed 2 or 3 devices. Follow-up transthoracic ultrasound study at 6 months showed the defect to be successfully closed in all 29 patients. After a mean follow-up time of 31 ± 19 months, all patients were alive and symptom-free. Patients with atrial septal aneurysm and associated ASD or PFO can be successfully treated with Amplatzer septal occluders.
