Table 2 The right coronary artery system bridg method

From: Perioperative observations of different bypass modes of a right coronary system based on instantaneous blood flow during the operation

  The right crown system bypass method Frequency Effective percentage
Group 1 Non-sequential single bypassa 178 67.9
Group 2 Non-sequential double bypassb 9 3.4
Group 3 Posterior descending branch-posterior branch of left ventricle 42 16.0
Group 4 Sequential bypass with 2 gyro systems and 1 right crown system 1 0.4
Group 5 Sequential bypass with 1 gyro system and 1 right crown system 20 7.6
Group 6 Sequential bypass with one forward descend system and one right crown system 2 0.8
Group 7 Sequential bypass with 1 roundabout system and 2 right crown systems 5 1.9
Group 8 Sequential bypass with 1 forward descending system, 1 gyrating system and 1 right crown system 2 0.8
Group 9 Y-bypass at two target sites in the right crown system 1 0.4
Group 10 Right target system, two target sites, one other system sequential bypass and one non-sequential single branch bypass 2 0.8
In total   262 100.0
  1. aIn the operation, the right crown system only has a single bypass
  2. bIn the operation, right coronary system separately set up two bypass
