In selected cases, patients with prior TV surgery may be candidates for percutaneous TV replacement.

Objectives: We sought to develop a scoring system that predicts the risk of serious adverse events (SAE's) for individual pediatric patients undergoing cardiac catheterization procedures. Background: Systematic assessment of risk of SAE in pediatric catheterization can be challenging in view of a wide variation in procedure and patient complexity as well as rapidly evolving technology. Methods: A 10 component scoring system was originally developed based on expert consensus and review of the existing literature. Data from an international multi-institutional catheterization registry (CCISC) between 2008 and 2013 were used to validate this scoring system. In addition we used multivariate methods to further refine the original risk score to improve its predictive power of SAE's. Results: Univariate analysis confirmed the strong correlation of each of the 10 components of the original risk score with SAE attributed to a pediatric cardiac catheterization (P < 0.001 for all variables). Multivariate analysis resulted in a modified risk score (CRISP) that corresponds to an increase in value of area under a receiver operating characteristic curve (AUC) from 0.715 to 0.741. Conclusion: The CRISP score predicts risk of occurrence of an SAE for individual patients undergoing pediatric cardiac catheterization procedures. V C 2015 Wiley Periodicals, Inc.

3DRA can be performed safely and effectively following CPC and may be more sensitive in diagnosing PA stenoses than 2D angiography. Quantitative measurements of PA diameter using 3DRA correlates well with 2D angiography.

Initiation of a high-risk program might decrease interstage mortality after high-risk neonatal palliative operations. Such an approach might contribute to earlier detection of significant residual/recurrent lesions amenable to therapy.

Thromboembolic phenomena, particularly pulmonary emboli, have been described in adult patients with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection, but have been less evident in children. We describe a case of a teenager with bilateral pulmonary emboli leading to cardiovascular collapse in the setting of a positive SARS‐CoV‐2 IgM antibody.

In this series, 75% of patients had a postoperative length of stay less than or equal to 2 weeks. Preoperative factors suggesting worse hypoxemia/decreased pulmonary blood flow (higher hemoglobin and lower oxygen saturation) and increased pulmonary artery pressure were associated with prolonged length of stay. These findings may help risk stratify this complex patient population, provide more accurate family counseling, and provide preliminary data for changes in preoperative timing of the Fontan and/or changes to postoperative management strategies for those at high risk for increased ICU morbidity.

The combination of goal-directed therapy and point-of-care testing was associated with a marked decrease in mortality for patients undergoing congenital heart surgery. Improvement was greatest in the highest risk patients.
