A coronary artery fistula is an abnormal connection between one of the coronary arteries and a heart chamber or another blood vessel of the pulmonary or systemic circulation, with the formation of left-to-left or left-to-right shunt, bypassing the myocardial capillary bed. We herein describe a rare clinical case of a young man presenting with acute myocardial infarction caused by posttraumatic coronary artery arteriovenous fistula thrombosis. Treatment consisted in successful endovascular disconnection of the pathological arteriovenous junction by an original author method, i. e., implantation of a self-expanding antithrombotic stent CASPER from the side of the fistula venous collector (coronary sinus). This case demonstrates present-day opportunities of endovascular methods of diagnosis and treatment of coronary artery fistulas.

A hypothesis concerning the orbital mechanism of formation of the IR absorption spectra of polyacrylonitrile and carbon fibres was advanced and quantitatively substantiated. The previously advanced hypothesis concerning the gravitational mechanism of formation of chemical bonds for a gravitational constant of ∼1028 cm3/g·sec2) was confirmed.
