Many parents with precordial disease are in a difficult position when it comes to choosing a surgical method for their baby, whether it is better to have a conventional large open-heart surgery or another more minimally invasive method. It turns out that most of the pre-cardiac diseases are operated through a median sternotomy, which is very traumatic and will leave a big scar in front of the chest after the child grows up, affecting the aesthetics, especially for girls, who can’t even wear low-necked clothes when they grow up, and will cause more or less disturbance to the child in the future. In these years, we try to choose minimally invasive interventions or minimally invasive small incisions to solve some suitable precordial diseases. Minimally invasive surgery with a small incision in the right axilla is a great option. Compared with a conventional chest incision, the small incision in the right axilla is more concealed and can solve the problem through a mere 3-5 cm wound. In the future, as long as the child does not deliberately tell anyone that he or she has had heart surgery, others will not be able to see it from the outside. The parents were very happy to see their child recovering so well with such a small and concealed wound. So which precardiac diseases are suitable for minimally invasive surgery with a small right axillary incision? Through our practice and experience there are the following: 1, atrial septal defect; 2, ventricular septal defect; 3, endocardial type pulmonary vein ectopic drainage; 4, partial endocardial cushion defect; 5, mitral valvuloplasty; 6, right ventricular outflow tract stenosis; 7, partial vascular ring; 8, mild case of tetralogy of Fallot. Of course, this small incision minimally invasive surgery requires the operator to have more experience, and we have accumulated through several years of practice that minimally invasive surgery for these precordial diseases has achieved the same results as conventional large open heart. Parents can contact Dr. Jin Yongqiang on the website for consultation if they need, and I will give you the most satisfactory answer.
