Q. How long does an atrial septal defect last?
Doctor Answer is medically reviewed by SecondMedic medical review team.
An atrial septal defect (ASD) is a type of congenital heart defect that is present at birth. Generally, how long it lasts depends on the size and type of ASD, as well as whether or not any other heart defects are present.
Smaller ASDs may closing on their own over time and heal without intervention; however, larger ASDs will typically require surgery to repair them. Even when treated with surgery, the amount of time an ASD can be expected to last varies depending upon the individual’s age, severity of damage to the heart valves and surrounding tissue from prior episodes of pulmonary hypertension due to increased blood flow through an already open defect, presence of coronary artery disease or myocardial infarction resulting in scarring within or around the area involved in closure procedure etc.
Typically simple closure techniques involving suturing together both walls of a septum involve additional back-up measures such as patches which can also help strengthen closure by providing additional support for shorter periods but usually carry with them a higher probability for recurrent defects later on down the line due to structural stress after prolonged exposure onto these materials compared against normal cardiac structures (endothelium).
In general though most permanent surgical repairs made are often successful in closing off all communication between left-sided and right-sided chambers forming an effective seal within itself leading towards lasting results that last anywhere between 10 – 20 years depending on circumstances mentioned previously and individuals aged 35+ tend towards longer closures post procedural intervention given their more stable physical conditions when compared against younger counterparts whom rarely experience recurrence rates after 5–7 years postoperative period following uncomplicated surgeries otherwise.
