[Aortic valve insufficiency in aneurysms of the ascending aorta: functional results following valve-sparing reconstruction].
Changes in geometry of the aortic root, especially a dilatation of the sinotubular junction, are the major causes of aortic valve regurgitation in ascending aortic aneurysm. In valves without structural defect, a valve sparing aortic root reconstruction may be a therapeutic option. Aim of this study was the assessment of functional results, in the early postoperative, and during follow-up, in a large patient cohort from one centre. ⋯ Valve sparing aortic root reconstruction is a promising alternative to the composite replacement of the ascending aorta. Low perioperative morbidity and mortality rates as well as favourable functional results were demonstrated. Long-term anticoagulation can be avoided. Long-term follow-up will be necessary to assess the definitive role of this new surgical approach.

[Treatment of the aortic valve and ascending aorta. The significance of reconstructive methods on the aortic root].
The standard surgical repair of disease of the aortic valve and the ascending aorta has been combined replacement, which includes the disadvantage of inserting a mechanical valve. We have investigated an individualized approach which preserves the native valve. ⋯ The described individualized approach makes it possible to preserve the native aortic valve in most patients with aortic regurgitation, at a low risk. Follow-up observations so far indicate good results of the reconstruction.
