**3.3 Right posterior mini-thoracotomy**

In our hands, this approach has been ideal for treating discrete SAS, PAPVD, and sinus venosus ASD. This technique was introduced for simple CHD since 2001. After the original description by Metras and Kreitmann in 1999 [14] for repairing simple CHD, we have modified it from a classic wide right posterior thoracotomy to a mini-thoracotomy, the RPMT (**Figure 7**). Currently, a 4-cm subscapular incision is employed for entering the chest in the fourth intercostal space [45]. This technique has been mainly used in female patients (under specific patient's request). Through this surgical approach, the aorta can be easily visualized and crossclamped, and aortic valve area can be exposed.
