Explain an atrial septal defect diagnosis to parents and plan the closure — OSCE

Communication framework

Establish what the parents already understand and fear. Ask them to recount what they have been told and what they have read online, and acknowledge their fear directly. Do not correct them before you have heard them; the fear of open heart surgery and a limited life are the ones you will spend the most time addressing, and you address them with the evidence that most secundum defects are closed with a keyhole device and that the outlook is excellent. [5]

Explain the atrial septal defect in plain language. The heart has four chambers, and between the two top chambers there is a wall called the atrial septum. Your daughter was born with a small hole in that wall, called an atrial septal defect. Because the pressure is slightly higher on the left side, a bit of extra blood flows from left to right through the hole, and that extra blood makes the right side of the heart work a little harder than it should. The sound the doctor heard — the murmur — is the sound of that extra blood flow. [5]

Reassure on cause and guilt. This is not caused by anything you did or did not do. It is a congenital condition, meaning your daughter was born with it, and it is one of the commonest heart conditions we find in children. You did not cause it, and you could not have prevented it. The reason we are finding it now is good news, because we have the chance to fix it before it causes any problems. [5]

The device option and the surgery distinction

Explain why this defect is likely device-closable. The echocardiogram shows that your daughter's hole is in the middle of the septum, the commonest type called a secundum defect, and there is enough tissue around the edges to hold a small device. That means a cardiologist can close the hole with a keyhole procedure, passing a thin tube through a vein in the leg and placing a small device across the hole, without open surgery. Most children go home the next day. [3]

Be honest about when surgery is needed. If the hole were in a different position, or the edges were too thin to hold a device, we would need surgery. That is a bigger operation with a longer recovery, but it is also very safe and very successful in the hands of a children's heart surgeon. For your daughter, the echocardiogram suggests the device is likely the right option, and the cardiologist will confirm that at the next appointment. [2]

The lifelong follow-up and honest prognosis

Address the fear of a limited life with evidence. This is the part that matters most. Once the hole is closed, your daughter's heart will return to normal, and she will grow, play sport, and live a full and typical life. The right side of the heart, which is working a little harder now, will shrink back to its normal size within a few months of the closure. The outlook for children whose holes are closed in childhood is excellent, and the life expectancy is close to that of any other child. [1]

Explain the lifelong follow-up. Even after the closure, we like to keep an eye on your daughter's heart for the rest of her life, because people with a repaired atrial septal defect have a slightly higher chance of an irregular heartbeat as adults. This is a simple check, usually once a year, and it is there to catch anything early. When she reaches her late teens, she will move to an adult heart doctor who specialises in people who had heart conditions as children, and that handover is planned and structured. [1] [2]

Close with shared planning and safety-netting

Agree a clear, written plan and a safety net. Give the parents the next appointment with the cardiologist, the likely timeline for the closure, and the number to call if they have questions or their daughter becomes unwell. Confirm their understanding by asking them to repeat the plan. Offer a link to a reliable support organisation, and book a follow-up within the week to reinforce the counselling once the shock has settled. [5]
