Background: Altered coagulation is a striking feature of COVID-19. Adult patients with congenital heart disease (ACHD) are prone to thromboembolic (TE) and bleeding complications., Objectives: The purpose of this study was to investigate the prevalence and risk factors for COVID-19 TE/bleeding complications in ACHD patients., Methods: COVID-19-positive ACHD patients were included between May 2020 and November 2021. TE events included ischemic cerebrovascular accident, systemic and pulmonary embolism, deep venous thrombosis, myocardial infarction, and intracardiac thrombosis. Major bleeding included cases with hemoglobin drop >2 g/dl, involvement of critical sites, or fatal bleeding. Severe infection was defined as need for intensive care unit, endotracheal intubation, renal replacement therapy, extracorporeal membrane oxygenation, or death. Patients with TE/bleeding were compared to those without events. Factors associated with TE/bleeding were determined using logistic regression., Results: Of 1,988 patients (age 32 [IQR: 25-42] years, 47% male, 59 ACHD centers), 30 (1.5%) had significant TE/bleeding: 12 TE events, 12 major bleeds, and 6 with both TE and bleeding. Patients with TE/bleeding had higher in-hospital mortality compared to the remainder cohort (33% vs 1.7%; P  < 0.0001) and were in more advanced physiological stage ( P  = 0.032) and NYHA functional class ( P  = 0.01), had lower baseline oxygen saturation ( P  = 0.0001), and more frequently had a history of atrial arrhythmia ( P  < 0.0001), previous hospitalization for heart failure ( P  < 0.0007), and were more likely hospitalized for COVID-19 ( P  < 0.0001). By multivariable logistic regression, prior anticoagulation (OR: 4.92; 95% CI: 2-11.76; P  = 0.0003), cardiac injury (OR: 5.34; 95% CI: 1.98-14.76; P  = 0.0009), and severe COVID-19 (OR: 17.39; 95% CI: 6.67-45.32; P  < 0.0001) were independently associated with increased risk of TE/bleeding complications., Conclusions: ACHD patients with TE/bleeding during COVID-19 infection have a higher in-hospital mortality from the illness. Risk of coagulation disorders is related to severe COVID-19, cardiac injury during infection, and use of anticoagulants., Competing Interests: The authors have reported that they have no relationships relevant to the contents of this paper to disclose., (© 2023 The Authors.)

Background: Adults with congenital heart disease (CHD) have been considered potentially high risk for novel coronavirus disease-19 (COVID-19) mortality or other complications., Objectives: This study sought to define the impact of COVID-19 in adults with CHD and to identify risk factors associated with adverse outcomes., Methods: Adults (age 18 years or older) with CHD and with confirmed or clinically suspected COVID-19 were included from CHD centers worldwide. Data collection included anatomic diagnosis and subsequent interventions, comorbidities, medications, echocardiographic findings, presenting symptoms, course of illness, and outcomes. Predictors of death or severe infection were determined., Results: From 58 adult CHD centers, the study included 1,044 infected patients (age: 35.1 ± 13.0 years; range 18 to 86 years; 51% women), 87% of whom had laboratory-confirmed coronavirus infection. The cohort included 118 (11%) patients with single ventricle and/or Fontan physiology, 87 (8%) patients with cyanosis, and 73 (7%) patients with pulmonary hypertension. There were 24 COVID-related deaths (case/fatality: 2.3%; 95% confidence interval: 1.4% to 3.2%). Factors associated with death included male sex, diabetes, cyanosis, pulmonary hypertension, renal insufficiency, and previous hospital admission for heart failure. Worse physiological stage was associated with mortality (p = 0.001), whereas anatomic complexity or defect group were not., Conclusions: COVID-19 mortality in adults with CHD is commensurate with the general population. The most vulnerable patients are those with worse physiological stage, such as cyanosis and pulmonary hypertension, whereas anatomic complexity does not appear to predict infection severity., Competing Interests: Funding Support and Author Disclosures The authors have reported that they have no relationships relevant to the contents of this paper to disclose., (Copyright © 2021 American College of Cardiology Foundation.

Objectives: The aim of this study was to test the hypothesis that narrowing the landing zone using commercially available endografts would enable transcatheter pulmonary valve replacement (TPVR) using commercially available transcatheter heart valves., Background: TPVR is challenging in an outsized native or patch-repaired right ventricular outflow tract (RVOT). Downsizing the RVOT for TPVR is currently possible only using investigational devices. In patients ineligible because of excessive RVOT size, TPVR landing zones were created using commercially available endografts., Methods: Consecutive patients with native or patch-repaired RVOTs and high or prohibitive surgical risk were reviewed, and this report describes the authors' experience with endograft-facilitated TPVR (EF-TPVR) offered to patients ineligible for investigational or commercial devices. All EF-TPVR patients were surgery ineligible, with symptomatic, severe pulmonary insufficiency, enlarged RVOTs, and severe right ventricular (RV) enlargement (>150 ml/m 2 ). TPVR and surgical pulmonary valve replacement (SPVR) were compared in patients with less severe RV enlargement., Results: Fourteen patients had large RVOTs unsuitable for conventional TPVR; 6 patients (1 surgery ineligible) received investigational devices, and 8 otherwise ineligible patients underwent compassionate EF-TPVR (n = 5 with tetralogy of Fallot). Three strategies were applied on the basis of progressively larger RVOT size: single-barrel, in situ fenestrated, and double-barrel endografts as required to anchor 1 (single-barrel and fenestrated) or 2 (double-barrel) transcatheter heart valves. All were technically successful, without procedure-related, 30-day, or in-hospital deaths. Two late complications (stent obstruction and embolization) were treated percutaneously. One patient died of ventricular tachycardia 36 days after EF-TPVR. Compared with 48 SPVRs, RV enlargement was greater, but 30-day and 1-year mortality and readmission were no different. The mean transvalvular pressure gradient was lower after EF-TPVR (3.8 ± 0.8 mm Hg vs. 10.7 ± 4.1 mm Hg; p < 0.001; 30 days). More than mild pulmonary insufficiency was equivalent in both (EF-TPVR 0.0% [n = 0 of 8] vs. SPVR 4.3% [n = 1 of 43]; p = 1.00; 30 days)., Conclusions: EF-TPVR may be an alternative for patients with pulmonic insufficiency and enlarged RVOTs ineligible for other therapies., Competing Interests: Author Disclosures Dr. Babaliaros is a consultant for and has received research grant support from Abbott Vascular and Edwards Lifesciences; and has equity in Transmural Systems.

Increasing numbers of women with repaired tetralogy of Fallot (rTOF) are reaching reproductive age and seek counseling regarding their cardiovascular risks related to pregnancy. Therefore, the aim of this study was to characterize changes in left ventricular (LV) strain in women with rTOF during pregnancy and in the postpartum period. Seventeen pregnancies in women with rTOF were included (mean age at repair = 3.2 years ± 5.5 years; mean age at delivery = 32.7 ± 4 years). Echocardiograms from three time periods were analyzed; baseline (prior to conception or in the first trimester), third trimester, and 4-6 weeks postpartum. Sixty-five percent of the patients had at least mild pulmonary regurgitation. Eight patients (47%) had undergone at least one pulmonary valve replacement. There were no changes in LV ejection fraction (EF) or circumferential strain across the three time periods. Significant differences were present in longitudinal strain within the three time points (p = 0.01). Postpartum strain decreased in magnitude compared to the third trimester value (- 17.7 ± 4.1 vs. - 21 ± 5, p-value = 0.003) but was not different when compared to baseline strain (- 17.7 ± 4.1 vs. - 19.4 ± 3.4; p-value = 0.15). In conclusion, in women with rTOF, changes in longitudinal strain were observed during pregnancy with a return to baseline after delivery; EF did not change. These findings provide evidence that pregnancy does not adversely impact LV mechanics in the short term in this potentially vulnerable patient population.

Background In adults with acquired heart disease, depression is common and associated with adverse outcomes. Depression may also be important in adults with congenital heart disease (CHD). Methods and Results We conducted a cohort study of outpatients with CHD, aged ≥18 years, enrolled in a prospective biobank between 2012 and 2017. Clinical data were extracted from medical records. Survival analysis assessed the relationship between depression, defined by a history of clinical diagnosis of major depression, with all-cause mortality and a composite outcome of death or nonelective cardiovascular hospitalization. A total of 1146 patients were enrolled (age, 38.5±13.8 years; 49.6% women). Depression had been diagnosed in 219 (prevalence=19.1%), and these patients were more likely to have severely complex CHD (41.3% versus 33.7%; P =0.028), cyanosis (12.1% versus 5.7%; P =0.003), and worse functional class (≥II; 33.3% versus 20.4%; P <0.0001), and to be taking antidepressant medication at time of enrollment (68.5% versus 5.7%; P <0.0001). Depression was associated with biomarkers indicative of inflammation (hsCRP [high-sensitivity C-reactive protein], 1.71 [25th-75th percentile, 0.82-4.47] versus 1.10 [0.45-2.40]; P <0.0001) and heart failure (NT-proBNP [N-terminal pro-B-type natriuretic peptide], 190 [92-501] versus 111 [45-264]; P <0.0001). During follow-up of 605±547 days, 137 participants (12.0%) experienced the composite outcome, including 33 deaths (2.9%). Depression was associated with increased risk for both all-cause mortality (multivariable hazard ratio, 3.0; 95% CI, 1.4-6.4; P =0.005) and the composite outcome (multivariable hazard ratio, 1.6; 95% CI, 1.1-2.5; P =0.025), adjusting for age, sex, history of atrial arrhythmia, systolic ventricular function, CHD complexity, and corrected QT interval. Conclusions In adults with CHD, major depression is associated with impaired functional status, heart failure, systemic inflammation, and increased risk for adverse outcomes.
