CYPHER and FIREBIRD stents are both widely used SES in China. However, comparative data concerning differences in long-term safety and efficacy regarding CYPHER and FIREBIRD stents in the Chinese population are still not available.展开更多

However, there is no consistent conclusion on surgical plan chosen for the particular patient. Methods Shunt configurations including central shunt(CS) and MBTS(Right mb T innominate;Left m BT subclavian) were virtually reconstructed for newborn based on preoperative CT data. Candidate shunt configurations were evaluated based on the parameters that were computed from the flow simulations. Results Vortex occurred at the anastomosis of the shunt and the aorta for all three shunt configurations. For CS, it produced the highest pulmonary artery(PA) flow, with the shunt ratio of44.6%. Blood flow in LPA was 8.5% higher than blood flow in RPA. For MBTS, the indexed power loss(i PL)of Right m BT innominate configuration was lower than that of Left m BT subclavian, which was 28.4% and 36.1%respectively. Conclusions The anastomosis of the shunt and the aorta is prone to cause thrombosis. CS configuration is prone to cause hyperemia due to excessive pulmonary blood flow. So, it could be considered for patients without a risk of overflow. It also causes non-symmetric PA flow in favor of LPA. For Right m BT innominate,which has the lowest i PL, tends to produce smaller vortex regions compared to CS and Left m BT subclavian. As for Left m BT subclavian, vortex currents formed when blood flows into the LPA could prevent the formation of thrombosis.[S Chin J Cardiol 2019;20(4):217-227]展开更多
