Details.
A minimally invasive procedure to close an atrial septal defect without surgery. An occluder is inserted through a tube in the groin and implanted in the heart. The procedure includes a transesophageal echocardiogram to determine suitability, consultation about risks and alternatives, pre-procedure blood work, local anaesthetic, intravenous sedation and pain relief, and post-procedure echocardiography. Patients should not eat or drink for 6 to 8 hours beforehand, bring a current medication list, and arrange for a friend or family member to accompany them home. Follow-up is scheduled 8 to 12 weeks after the procedure.
