Atrial Septal Defects (ASD) and Patent Foeamen Ovale (PFO)
For patients with Atrial Septal Defects (ASD) and Patent Foeamen Ovale (PFO) closure is sometimes recommended.
To close some ASDs an open heart surgery operation may be required whilst a machine takes on the work of the heart and lungs (cardiopulmonary bypass). The operation can be performed through the breastbone (midline sterrnotomy) or through the side of the chest (thoracotomy). The hole is then closed with a patch.
Many ASDs and almost all PFOs however can be closed using a transcatheter technique and a small closure device to seal the hole. A catheter is passed through the femoral vein (in the groin) and passed up to the right atrium of the heart. A wire is then passed through the hole using X-ray and ultrasound guidance into the left atrium. The device is then deployed to close the hole.
Dr Dalby will discuss any proposed procedure with you including its attendant risks and benefits. When appropriate this will involve further discussion in a multidisciplinary meeting so that you may receive the best advice and reach a mutually agreeable management plan.
