On February 20, at 3 p.m., a charity event dedicated to supporting parents raising disabled children will be held in Kazan at 28 Sibirsky Trakt Street ("Good Kazan").
The interventions were carried out with an interval of one day under the guidance of a specialist from the Northern Capital, Evgeny Shloido. A new technique, transcatheter valve implantation in the position of a previously installed bioprosthesis, avoids repeated traumatic open surgery.
