    Abstract Background: The surgical outcomes of tetralogy of Fallot (TOF) have evolved dramatically and have resulted in lower mortality rate. Currently, the many cardiac centers have a trend to early single-stage complete repair more than a staged repair. However, the patients who have an early primary repair were required transannular patch augmentation of a pulmonary valve frequently. This effect has been developed a chronic pulmonary insufficiency may lead to right ventricular dilation, dysfunction. In this era, the aim of treatment of TOF is attempted to preserve pulmonary valve annulus for prevent right ventricular dysfunction in the future. The systemic to pulmonary… More >

    Risk Factor Analysis for Shunt Failure after Systemic Pulmonary Shunt

    Han Zhang, Gang Li, Xiangming Fan, Junwu Su*

    Congenital Heart Disease, Vol.15, No.5, pp. 361-367, 2020, DOI:10.32604/CHD.2020.013020

    Abstract Background: To identify factors associated with shunt failure in patients with a systemic pulmonary shunt (SPS). Methods: We retrospectively assessed 451 patients who received SPS. Perioperative parameters such as hemoglobin, Nakata Index, and shunt size were assessed, and factors influencing shunt failure after an initial palliative shunt operation were analyzed. Results: We analyzed 451 patients who underwent isolated SPS surgery at Anzhen Hospital. Of these, shunt failure occurred in 48 (10.6%) cases after a median of 6.5 days. The 30-day mortality rate was 2.1%. Univariate and logistic regression analysis revealed that a Nakata Index ≤ 105 and vasoactive-inotropic score (VIS)… More >
