We have read the letter regarding our case report published in Heart, Vessels and Transplantation (1, 2). We thank authors for kind thought of our case report. We agree completely with authors about the lack of the additional method of diagnostics, also that the main factor determining the clinical importance of coronary artery anomalies is their hemodynamic significance. In our case we determined the hemodynamically significant dysfunction of the coronary circulation by clinical symptoms and electrocardiogram to choose advanced treatment tactic.

Unfortunately, in our practice we did not use such method of diagnostic as MIP, which you noted. But we hope that in the immediate future we will be able to contribute more efficiency data to answer on all issues exercising scientific commonwealth.

With great regards,
