After nearly one hour of complete endoscopic surgery, the surgical team found a hole in her heart.

Professor Song Jin Young, the main operative of the surgical team, said: "Toan was contracted at the heart, one of the most common congenital heart diseases, accounting for nearly 30% of congenital heart disease. To seal the hole in his heart, the operative put a small catheter from the femoral vein up to the heart, using a special device to place an artificial patch to seal the pectoralis while his heart was still full, normal beat.

This is a modern laparoscopic procedure, which has been used by Samsung Hospital to treat thousands of patients inside and outside Korea. The advantage of this method is the small incision, the ability to recover quickly, reduce pain compared with open surgery. The length of hospital stay after surgery was also significantly shortened, less complications, less risk of wound infection.
