OBJECTIVE

To analyze functional state of venous conduits depending on bypass of various segments of the right coronary artery (RCA).

MATERIAL AND METHODS

Functional analysis included 98 venous conduits to RCA pool (51 (52%) grafts to RCA bifurcation, 47 (48%) grafts to the branches of RCA (posterior descending artery (PDA) or posterolateral branch (PLB)). Functional viability of the conduits was assessed using control angiography. Mean time from surgery to angiography was 20.4±8.7 months. The diameter over 1.5 mm was in 87 (88.8%) arteries. Occlusion of native artery was observed in 57 (58.2%) cases.

RESULTS

Satisfactory function of venous conduits to RCA pool was revealed in 76 (77.5%) cases. Function of the conduits was significantly better in the cases of bypass of RCA branches (PDA and PLB) compared with RCA per se (40 (85.1%) vs. 36 (70.6%), respectively, p<0.05).

CONCLUSION

Analysis of RCA revascularization shows significantly better functional consistency of conduits to PDA and PLB in comparison with RCA bifurcation.
