Objective To explore the strategies and implementation techniques of ministernotomy for most cardiac surgery.

Results The ministernotomy completely cuts the sternum, but reduces the length of the conventional incision from 20 cm to 6-8 cm, and the sternum is only 6 cm opened. It can perform most heart surgery with great results. It has a wide range of indications, smaller incisions and beautiful appearance, minimal impact on the thorax, and a heart with a mid-thoracotomy. The heart is clearly exposed, the operation is rapid and accurate, and no need for single lung ventilation.
