The excellent contributions in this volume have highlighted not only the continuing success, but also the progress and innovations made in aortic valve and root surgery during the past 50 years. Perioperative aortic root imaging techniques (echocardiography, computed tomography, and magnetic resonance imaging) have become important diagnostic tools in the planning and evaluation of surgical procedures in the aortic root. Aortic valve and root surgery is now routine with low perioperative morbidity and mortality as well as long-term improvement in survival and quality of life. Risk-adjusted operative mortality for aortic valve replacement is 3.9% and for aortic valve replacement with concomitant coronary artery bypass grafting, it is 6.3% according to the database of the German Society for Cardiothoracic and Vascular Surgery, whereas both operations carry a mortality rate of 5% according to the Society of Thoracic Surgeons. Reoperative mortality in many institutions did not differ statistically from that for primary aortic valve replacement and ranges from 1.5–6%. Reoperative risk for prosthetic valve endocarditis was 9–20%.
