[Aortic valve sparing operations and reconstruction--from anatomy to the long-term results].

The implantation of an artificial heart valve (a mechanical valve or a xenograft valve) involves the risk of serious and life-threatening complications for the patient, such as hemorrhagic complications, thromboembolic complications, the risk of endocarditis, the risk of premature degeneration of the xenograft valve, etc. Preserving the patient's own aortic valve eliminates or at least significantly reduces the above complications. On the other hand, it brings about the disadvantage of a technically more demanding surgery and the possible risk of reoperation due to failure of the spared aortic valve. The authors present a comprehensive and up-to-date view ofthe issue of aortic valve sparing surgeries and plastic corrections, beginning with the basics of aortic root anatomy and ending with the indications and principles of cardiosurgical techniques, and long-term results.
