Median sternotomy incision has shown to be a safe and efficacious approach in patients who require thoracic aortic interventions and still represents the gold-standard access. Nevertheless, over the last decade, less invasive techniques have gained wider clinical application in cardiac surgery becoming the first-choice approach to treat heart valve diseases, in experienced centers. The popularization of less invasive techniques coupled with an increased patient demand for less invasive therapies has motivated aortic surgeons to apply minimally invasive approaches to more challenging procedures, such as aortic root replacement and arch repair. However, technical demands and the paucity of available clinical data have still limited the widespread adoption of minimally invasive thoracic aortic interventions. This review aimed to assess and comment on the surgical techniques and the current evidence on mini thoracic aortic surgery.

Bentall operation via median sternotomy has been largely shown to be safe and long-term efficacious and currently represents the Bgold standard^intervention in patients presenting with aortic valve and root disease. However, over the last years, minimally invasive techniques have gained wider clinical application in cardiac surgery. In particular, minimally invasive aortic valve replacement through ministernotomy has shown excellent outcomes and becomes the first choice approach in numerous experienced centers. Based on these favorable results, ministernotomy approach has also been proposed for complex cardiac procedures such as aortic root replacement and arch surgery. Herein, we present our technique for minimally invasive Bentall operation using a ministernotomy approach.

Despite promising early results, use of nitinol mesh for saphenous veins was disappointing in our experience. Further refinements are probably needed.
