Monsefi N, et al. - This study is performed to assess the relative results of David procedure through conventional or minimally invasive approach. For selected patients with aortic root aneurysm and aortic valve incompetence, the minimally invasive aortic valve reimplantation procedure is a durable procedure with minor valve-related morbidity and mortality at the mid-term follow-up. The minimally invasive group has significantly lower intra- and perioperative application of packed red blood cells.
