When you write about this man, it begs the epithet the ‘first’. Indeed, the operations and methods, he first tested in practice, were then successfully implemented in the clinic. These are various operations performed in the baro-operative mode of remote control, electrical isolation of the left auricle, cardiac denervation, modeling heart defects of the blue and pale types, etc. From the newest methods – cryoablation, fulguration, laser photoablation, now widely used not only in our country, but also abroad. Leo Antonovich became a pioneer in the use of computer methods in diagnostics, in modeling pathology of the circulatory system, gas exchange, arrhythmias. He developed a new method, introduced it, and performed about 2,000 open-heart surgeries for tachyarrhythmias. How to be in time to do everything without undermining your health, how not to reinvent the wheel, but invent many useful things, and also about where love is concentrated in the human heart, and about much else – conversation with Leo A. Bockeria, director of the Bakulev Scientific Center for Cardiovascular Surgery.
