A variety of minimally-invasive approaches for aortic valve replacement (AVR) have been developed and are increasingly being utilized. The different approaches described, such as partial upper sternotomy, right parasternal thoracotomy or transverse sternotomy have the aim to decrease invasiveness and reduce surgical trauma. Whereas port access surgery with remote cannulation has the attendant risks inherent with peripheral cardiopulmonary bypass and limitations in terms of myocardial protection and adequate cardiac dearing, partial sternotomies or thoracotomies may be associated with suboptimal chest wall reconstruction. Here described is a technique of minimal-access aortic valve replacement, which entails limited skin incision and full median sternotomy. Advantages of the present approach include a superior cosmetic result, when compared to standard sternotomy incision, and the safety of the midline access, which may be immediately converted into standard approach, in case of need, and is associated with stable chest wall reconstruction. Selective indications and outcome of minimal-access AVR are discussed.
