Abstract
PURPOSE In children with a mitral annulus too small to accommodate traditional prostheses, surgical implantation of stent-based valves is a promising option. However no reliable preoperative methods exist to guide patient selection, device sizing, and positioning. We describe a novel methodology to visualize and quantify device fit in 3-dimensional echocardiogram (3DE)-derived heart models. DESCRIPTION Heart models were created from existing preoperative 3DEs using custom software. Valve models were virtually implanted into the models, and both device fit and left ventricular outflow tract (LVOT) area were quantified. EVALUATION The 3DEs of 3 patients who underwent Melody valve placement in the mitral position were retrospectively modeled: 1 with LVOT obstruction, 1 with perivalvar leak, and 1 without complications. In all cases 2-dimensional measurements underestimated 3D annular dimensions, and the patient with clinical LVOT obstruction had the lowest predicted LVOT area-to-aortic area ratio (0.5). CONCLUSIONS 3DE-based preoperative modeling of surgical implantation of stent-based valves in the mitral position may improve quantification of mitral valve dimensions and inform risk stratification for potential LVOT obstruction.

Abstract
Abstract
OBJECTIVES
The aim of this study was to determine mid-term outcomes of patients with anomalous origin of the left coronary artery from the pulmonary artery undergoing coronary repair only (group A) or simultaneous mitral valve repair (group B).
METHODS
Patients with anomalous origin of the left coronary artery from the pulmonary artery who underwent surgery from 2000 to 2017 were reviewed. Mitral regurgitation (MR) grade (none, mild, moderate, severe), left ventricular (LV) function [ejection fraction (EF): <40%, 40–50%, >50%] and LV Z-scores (long axis) were assessed preoperatively and at last visit. Outcomes were compared within/between the groups using the Wilcoxon signed-rank test.
RESULTS
Of 58 patients (67% women; median age 4.4 months), 39 patients were in group A (67%) and 19 patients in group B (33%). The median hospital stay (11 days, interquartile range 5–18) and average follow-up time (2.6 ± 0.5 years) did not differ significantly between the groups (P > 0.05). Four patients in group A (10.3%) underwent mitral valve reintervention. The median MR grade differed significantly between the groups preoperatively (2 vs 3, P < 0.001) but not at the last visit (2 vs 2, P = 0.88); both groups improved significantly (P = 0.021, P < 0.001). EF grade (<40%, 40–50%, >50%) did not differ significantly between the groups at baseline (group A: 38%/23%/38% vs group B: 58%/10%/32%, P = 0.32) or at last visit (group A: 18%/15%/67% vs group B: 26%/16%/58%, P = 0.75); both groups improved significantly (P = 0.004, P = 0.014). The mean LV Z-scores for groups A and B were 3.1 ± 0.5 and 4.5 ± 0.6 before surgery (P < 0.05) and 1.5 ± 0.3 and 2.7 ± 0.6 at last visit (P = 0.77).
CONCLUSIONS
The repair of anomalous origin of the left coronary artery from the pulmonary artery is associated with improvement in MR, EF and LV dimensions. However, in cases of ≥moderate MR, the risk of mitral valve reintervention may be higher in patients undergoing coronary transfer only.

Abstract
At our institution a multidisciplinary team has performed fetal aortic valvuloplasty (FAV) for severe aortic stenosis with evolving hypoplastic left heart syndrome with high technical success rates. Measurement of postnatal success has been biventricular circulation (BC). Postnatal survival for patients after FAV who achieved a BC appears encouraging. However, there are limited late clinical and hemodynamic outcomes in this cohort and there is concern for diastolic dysfunction. We reviewed all patients with FAV at our institution who initially underwent single ventricle palliation and subsequently BC, as this is likely the subset at high-risk for poor outcomes. Clinical, imaging, and surgical data were collected. Two of 7 patients (29%) died within 16 months of BC, and 1 patient has been listed for transplant. Diastolic dysfunction was common and progressive with median left ventricular end diastolic pressure of 12 mm Hg before BC, and increasing to 22 mm Hg for survivors at last follow-up. Left ventricular size was adequate with all patients reaching a left ventricular end diastolic volume (LVEDV) z score in the normal or elevated range. Presence and severity of residual valve lesions decreased over time secondary to a median of 6 interventions (range 3 to 10), either surgical or cath-based, performed for these 7 patients during the study period. In conclusion, clinical outcomes are concerning for this high-risk group. Diastolic dysfunction is persistent and progressive despite anatomic interventions and adequate left ventricular growth. The main contributing factor to poor outcomes may be intrinsic myocardial dysfunction and primordial pathology. Achievement of a BC after FAV may not be an appropriate measure of success.

Abstract
BACKGROUND In addition to tricuspid regurgitation (TR) and right ventricular (RV) enlargement, patients with Ebstein anomaly are at risk for left ventricular (LV) dysfunction and dyssynchrony. We studied the impact of the cone tricuspid valve reconstruction operation on LV size, function, and dyssynchrony. METHODS All Ebstein anomaly patients who had both pre- and postoperative cardiovascular magnetic resonance (CMR) studies were retrospectively identified. From cine images, RV and LV volumes and ejection fractions (EF) were calculated, and LV circumferential and longitudinal strain were measured by feature tracking. To quantify LV dyssynchrony, temporal offsets (TOs) were computed among segmental circumferential strain versus time curves using cross-correlation analysis and patient-specific reference curves. An LV dyssynchrony index was calculated as the standard deviation of the TOs. RESULTS Twenty patients (65% female) were included with a median age at cone operation of 16 years, and a median time between pre- and postoperative CMR of 2.8 years. Postoperatively, there was a decline in the TR fraction (56 ± 19% vs. 5 ± 4%, p < 0.001), RV end-diastolic volume (EDV) (242 ± 110 ml/m2 vs. 137 ± 82 ml/m2, p < 0.001), and RV stroke volume (SV) (101 ± 35 vs. 51 ± 7 ml/m2, p < 0.001). RV EF was unchanged. Conversely, there was an increase in both LV EDV (68 ± 13 vs. 85 ± 13 ml/m2, p < 0.001) and LV stroke volume (37 ± 8 vs. 48 ± 6 ml/m2, p < 0.001). There was no change in LV EF, or global circumferential and longitudinal strain but basal septal circumferential strain improved (16 ± 7% vs. 22 ± 5%, p = 0.04). LV contraction become more synchronous (dyssynchrony index: 32 ± 17 vs. 21 ± 9 msec, p = 0.02), and the extent correlated with the reduction in RV EDV and TR. CONCLUSIONS In patients with the Ebstein anomaly, the cone operation led to reduced TR and RV stroke volume, increased LV stroke volume, improved LV basal septal strain, and improved LV synchrony. Our data demonstrates that the detrimental effect of the RV on LV function can be mitigated by the cone operation.

Abstract
Current laboratory methods for comprehensive thrombophilia status require large blood volumes and long turn-around times. We demonstrate the feasibility of performing thrombophilia panel testing of enzymatic functional assays on a microfluidic cartridge using low sample volume.Functional assays for Antithrombin III, Protein C, Factor VIII, and plasminogen were adapted on the digital microfluidic platform by developing novel fluorogenic substrates and establishing on-cartridge fluorescence (360/460 nm) detection. Cartridge vs. microtiter plate results were compared using samples obtained from pediatric patients. Linear regression and Bland-Altman plots were used to establish correlations. Results were not significantly different when performed on-cartridge compared to microtiter plates. Importantly, the sample volume required is significantly lower for all on-cartridge compared to microtiter plate assays (25 μL vs. 2 ml).This study demonstrates the feasibility of thrombophilia panel testing with high-fidelity using small plasma volume. The efficacy of this near-patient technology in clinical settings needs further investigation.

Abstract
The epidemic of Zika virus (ZIKV) has resulted in a surge of newborns with microcephaly and brain abnormalities. In this report, we describe the first case, to our knowledge, of congenital Zika syndrome with concomitant critical congenital heart disease. The mother had a confirmed ZIKV infection in the first trimester of pregnancy. Fetal ultrasonography at 31 weeks of gestation revealed cerebral cortical calcifications and hypoplastic left heart syndrome. The severity of brain involvement was assessed by postnatal magnetic resonance imaging and echocardiogram, and palliative surgery was performed. The ethical dimensions of this infant's clinical management are discussed. ZIKV is known to affect neural progenitor cells, but whether it could have a tropism for other tissues remains unclear.

Abstract
Essentials Perioperative thrombosis is a major cause of morbidity and mortality in congenital heart disease. Neonates and infants undergoing repair of congenital heart lesions were prospectively followed. Elevated von Willebrand factor (VWF) to ADAMTS-13 activity ratios typified the postoperative period. Thrombosis was associated with preoperative VWF activity and cryoprecipitate transfusion SUMMARY: Background The surgical repair of congenital heart malformations is frequently complicated by perioperative thrombosis of unclear etiology. An imbalance between von Willebrand factor (VWF) and ADAMTS-13 is an emerging variable in thrombosis. Objectives To describe perioperative changes to VWF, ADAMTS-13 and NETosis, and evaluate clinical and biochemical associations with postoperative thrombosis. Methods Neonates and infants undergoing palliation or definitive surgical repair of congenital heart malformations were recruited (n = 133). Preoperative and postoperative plasma levels of VWF, ADAMTS-13 and markers of NETosis were determined. Patients were followed for up to 30 days for the occurrence of thrombosis. Univariate and multivariate logistic regression analyses were conducted to identify variables associated with thrombosis. Results We identified significant postoperative increases in VWF activity, VWF level, DNA-histone complexes and cell-free DNA with an overall decrease in ADAMTS-13 activity. Patients experiencing postoperative thrombotic events (9%) were characterized by surgery performed at a lower intraoperative temperature, higher preoperative lactic acid levels, and higher preoperative VWF activity and level. A multivariate logistic regression model identified preoperative VWF activity (odds ratio (OR) 8.39 per IU mL-1 , 95% confidence interval [CI] 1.73-40.55) and transfusion of cryoprecipitate (OR 1.10 per mL kg-1 , 95% CI 1.03-1.17) as being associated with thrombosis. Conclusions Pediatric patients undergoing surgical repair of congenital heart malformations are exposed to high levels of VWF with diminished or minimal change to ADAMTS-13 in the immediate postoperative period. Elevated preoperative VWF activity is associated with postoperative thrombosis in pediatric congenital heart disease.

Abstract
Notwithstanding remarkable progress in vascular network engineering, implanted bioengineered microvessels largely fail to form anastomoses with the host vasculature. Here, we demonstrate that implants containing assembled human vascular networks (A-Grafts) fail to engraft due to their inability to engage non-inflammatory host neutrophils upon implantation into mice. In contrast, unassembled vascular cells (U-Grafts) readily engage alternatively polarized neutrophils, which in turn serve as indispensable mediators of vascular assembly and anastomosis. The depletion of host neutrophils abrogated vascularization in U-Grafts, whereas an adoptive transfer of neutrophils fully restored vascularization in myeloid-depleted mice. Neutrophil engagement was regulated by secreted factors and was progressively silenced as the vasculature matured. Exogenous addition of factors from U-Grafts reengaged neutrophils and enhanced revascularization in A-Grafts, a process that was recapitulated by blocking Notch signaling. Our data suggest that the pro-vascularization potential of neutrophils can be harnessed to improve the engraftment of bioengineered tissues.
