Flow Dynamics of Bilateral Superior Cavopulomonary Shunts Influence Outcomes After Fontan Completion.

摘要: Bilateral superior vena cava (SVC), which occurs following bilateral bidirectional cavopulmonary shunt (BCPS), is an anomaly marked by unique hemodynamics. This study aimed to determine its effects on outcomes after Fontan completion. Among 405 patients who underwent BCPS and total connection (TCPC) between 1997 2017, 40 required a bilateral-BCPS. The dominant SVC prior TCPC was identified according the direction of blood flow in central pulmonary artery, relationship inferior (IVC) classified as concordant or discordant relationship. Preoperative factors were analyzed identify risk for specific adverse outcomes. length intensive care unit (ICU) stay longer bilateral-BCPS than those unilateral (p = 0.024), survival rate lower former group latter (p = 0.004). In bilateral-BCPS, with IVC 30 10 patients. With regard whether certain morphological, hemodynamic, dynamics-related variables TCPC, independent factor both ICU (p = 0.037, HR 2.370) worse (p = 0.019, 13.880). Therefore, have previously undergone might contribute TCPC.
