Background: From the perspective of interventional CHD treatment, bifurcation stenosis of the coronary arteries is referred to as a “difficult” lesion, accounting for 15-20% of the total number of atherosclerotic lesions of the coronary bed. The most obvious disadvantage of current bifurcation stenting methods is considerable local “metallization” of a stented artery as a result of putting one stent to another, as well as the disruption of the polymer-drug layer of stents during operations.

The goal of this study is to see how well the method of cardiography from the coronary sinus (ECG-CS) can help with stenting bifurcation lesions (BL) in the coronary arteries (CA).

Materials and Procedures: This study comprised 43 individuals with stable CHD with pseudo-BL of the anterior descending artery (ADA). At the start of percutaneous coronary intervention, we inserted a 10-canal electrode into their coronary sinus (PCI). The WorkMate electrophysiological recording equipment was used for ischemic guiding.

According to ECG-CS, the diagonal branch (DB) comprometation and ischemia dynamics (p0.05) in intracardiac lead (CS 3-4) after ADA stenting were discovered in 11 patients (25%) out of 43 with CHD. The provisional-T-stenting of nine patients (20.9 percent) was effective, whereas the other two patients required a second stent. Conclusion: ECG-CS allows for better coronary intervention in the vicinity of the CA bifurcation.
