On July 27, 2021 I checked out of the hospital. I can express endlessly my gratitude to the head of the Department Bykova Svetlana Vladimirovna. A person and a professional who saved more than one life, including me in 2013, and continues to do so. Of course sensitive, competent and attentive to everyone and to patients and staff. Svetlana Vladimirovna, I sincerely wish you good health, success and prosperity. Thank you so much for everything. There are not enough words to express all gratitude to you.
