Adult Congenital Defects (ASD and PFO) Closures

 Some patients have congenital defects which result in an opening or hole between two chambers of their heart leading to the abnormal mixing of blood from one chamber with the other. Common examples are atrial septal defects (ASD) or patent foramen ovale (PFO). These birth defects can cause symptoms such as fatigue and shortness of breath and can also potentially result in a stroke. If these symptoms worsen then it may be recommended that the patient have a procedure to repair the defect.

At ACI we can do a cath lab based procedure for selected adult patients with either an ASD or PFO. Once the patient is deemed a suitable candidate by our specialist doctor, the size of the defect is measured with a specialized echocardiogram in preparation to prepare for the procedure. A catheter is inserted through a small puncture in the groin area into a blood vessel and advanced under X-ray guidance to the heart.  A closure device is then advanced though the catheter and positioned in the abnormal opening of the heart.  Once in position, the device is opened to close the defect and is released and the catheter withdrawn.  The procedure is done under general anaesthesia and takes between 1 to 2 hours.  The patient stays in the hospital overnight and is usually discharged the following day.
