This is how well 14-year-old David looks and feels, whom Prof. Borys Todurov operated on for the first time 5 years ago, performing an extremely complex operation on a child’s heart, and now having operated on the boy for the second time. This was the same heart surgery during which, resulting from the Russian shelling, the light in the operating room went out for a while.

5 years ago, Boris Todurov performed a unique Ozaki operation to reconstruct the aortic valve from its own pericardium. This allowed the aortic ring to grow to adult size and now to install a mechanical valve that, under favorable conditions, will last for David a lifetime.
