This technique which involves a less invasive incision that the usual full midline sternotomy incision is not suitable for a Ross procedure, but may be appropriate for either mechanical or tissue (bioprosthesis) aortic valve replacement (AVR), providing the patient’s body habitus is suitable and C.T. scan imaging shows that the aortic valve can be approached safely via a less invasive approach.
The two main approaches used are upper hemisternotomy where only the top half of the sternum requires opening and right anterior thoracotomy (RAT) via a 5 cm. to 6 cm. transverse incision as shown in the diagram.
