Minimally invasive surgery for precardiac disease does not require opening of the chest, extracorporeal circulation, opening of the heart, suturing of any kind, and general anesthesia for children in the older age groups. These features have great advantages over surgical procedures. The patient recovers quickly after treatment (he can be discharged 5 days after treatment), there are few complications after treatment, and the skin is not scarred, which are additional features of minimally invasive surgery. The total risk of minimally invasive surgery is less than that of surgery, and it is a typical minimally invasive treatment method that is gradually replacing surgical procedures.
