RESUMO
INTRODUCTION: Fetal echocardiograms (F-echo) are recommended in all pregnancies when maternal congenital heart disease (CHD) is present, even if there was a prior level II ultrasound (LII-US) that was normal. The goal of this study was to evaluate if any diagnosis of a critical CHD was missed in a fetus with maternal CHD who had a normal LII-US. METHODS: A retrospective chart review of all F-echoes where the indication was maternal CHD between 1/1/2015 to 12/31/2022 was performed. Fetuses were included if they had a LII-US that was read as normal and had an F-echo. Critical CHD was defined as CHD requiring catheterization or surgical intervention < 1 month of age. RESULTS: A total of 296 F-echoes on fetuses with maternal CHD were evaluated, of which 175 met inclusion criteria. LII-US was performed at 19.8 ± 2.9 weeks gestational age and F-echo was performed at 24.2 ± 2.8 weeks gestational age. No patient with a normal LII-US had a diagnosis of a critical CHD by F-echo (negative predictive value = 100%). Evaluating those patients that had a negative LII-US, ten patients were diagnosed with non-critical CHD postnatally (negative predictive value = 94.3%). F-echo correctly diagnosed two of the ten missed LII-US CHD. CONCLUSIONS: Critical CHD was not missed with a normal LII-US in this at risk population. F-echo also missed the majority of CHD when a LII-US was read as normal. A cost-benefit analysis of screening F-echo in fetuses with maternal CHD should be conducted if a normal LII-US has been performed.
RESUMO
BACKGROUND: Data on the use of implanted hemodynamic monitoring (IHM) in patients with Fontan circulation are limited. This study reports our experience using the CardioMEMS HF system in adults with Fontan circulation. METHODS AND RESULTS: This single-center, retrospective study evaluated heart failure hospitalizations, procedural complications, and device-related complications in patients with Fontan circulation referred for IHM placement (2015-2022). The association of pulmonary artery pressure (by most recent catheterization and median IHM pressure within 30 days of placement) with both death and follow-up Model for End-Stage Liver Disease Excluding International Normalized Ratio score were evaluated. Of 18 patients referred for IHM placement, 17 were successful (median age, 30 [range 21-48] years, 6 women). Procedural complications (access site hematomas, pulmonary artery staining) occurred in 3 patients, without device-related procedural complications. In follow-up (median, 35 [range, 6-83] months), 1 patient developed a pulmonary embolism (possibly device-related). Heart failure hospitalizations/year were similar before and after IHM (median, 1 [interquartile range, 0-1.0] versus 0.6 [0-2.3]; P=0.268), though only 46% of heart failure hospitalizations had associated IHM transmissions. IHM pressures were associated with Model for End-Stage Liver Disease Excluding International Normalized Ratio scores (R2=0.588, P<0.001), though catheterization pressures were not (R2=0.140, P=0.139). The long-term mortality rate was 53% in this cohort. On unadjusted survival analysis, IHM pressures ≥18 mm Hg were associated with mortality (log rank P=0.041), which was not reproduced with catheterization pressures (log rank P=0.764). CONCLUSIONS: In patients with Fontan circulation, IHM did not reduce heart failure hospitalizations, though patient adherence to transmission was low. Device-related complications were low. IHM pressures may better represent real-life conditions compared with catheterization given associations with mortality and Model for End-Stage Liver Disease Excluding International Normalized Ratio score.

Introduction: The COVID-19 pandemic has resulted in increased use of telemedicine. There are limited data on patient experience with telemedicine in adults with congenital heart disease (ACHD). We hypothesized that due to their complex medical history, ACHD would prefer in-person clinic visits over telemedicine. Methods: We conducted a nurse-administered telephone survey based on Agency for Healthcare Research and Quality recommendations to assess patient experience after ACHD telemedicine visits in the early part of the pandemic from March 2020 to June 2020. Results: Of 216 ACHD who had telemedicine visits, 136 (63%) agreed to participate in the survey. Mean age was 45 ± 18 years, majority (65%) being video encounters. Most (98%) patients expressed that the telemedicine visit was successful in addressing their health care needs. Only 21 (15%) patients reported technical issues. Most patients (76%) preferred telemedicine given testing was provided separately, 25 (18%) preferred in-person clinic visits, and 8 (6%) had no preference. Of the 25 patients over 65 years, 19 (76%) would choose telemedicine over the in-person clinic, and only 1 patient reported technical difficulties. Conclusion: ACHD reported a positive experience with telemedicine. Technical limitations were infrequent even among the elderly. The majority of patients felt that their health care needs were addressed and would consider telemedicine over clinic visits. These data are important as payors move away from supporting telemedicine and hospitals restructure, with and without ongoing COVID-19 concerns.

OBJECTIVES: Left heart obstruction in pregnancy is associated with higher rates of morbidity/mortality. The primary aim of this study was to evaluate maternal cardiovascular, obstetric, and fetal/infant events in pregnant women with left heart obstruction. STUDY DESIGN: Pregnant women with current or repaired left heart obstruction were retrospectively analyzed (2000-2014): mitral stenosis, left ventricular outflow tract obstruction (subvalvar, valvar, supravalvar), and coarctation of the aorta. Maternal cardiovascular events were defined as: heart failure, arrhythmia, urgent/emergent cardiac surgery or percutaneous transcatheter intervention, transient ischemic attack/cerebrovascular accident, and death up to 6 months postpartum. RESULTS: There were 90 pregnancies in 67 women (29±7 years old) who had 15 maternal cardiovascular events. Isolated mitral stenosis (n=6) or >1 serial left heart obstructive lesion (n=6) were the source of the event in the majority pregnancies. Women with isolated mitral stenosis had increased cardiovascular events compared to other single left heart obstructive lesions (OR 18.6, 95% CI: 3.8-91.1). If >1 serial obstructive lesion was present, there was also an increased risk of maternal cardiovascular events (OR 6.8, 95% CI: 1.6-29.1), however isolated mitral stenosis carried similar risk to serial left heart obstructive lesions (OR 2.7, 95% CI: 0.7-11.2). Baseline characteristics associated with events included: New York Heart Association functional class >2 (27% vs. 0, p<0.001), any current left heart obstruction (73% vs. 36%, p=0.01), severe left heart obstruction (40% vs. 29%, p<0.001), and higher Cardiac Disease in Pregnancy ("CARPREG") score (1.2±0.7 vs. 0.5±0.7, p=0.01). There was no difference in rate of obstetric/fetal/infant complications in women with cardiovascular events; however, term birth weight was lower (2.7±0.5 vs. 3.1±0.6kg, p=0.01). There was no maternal mortality. CONCLUSIONS: Isolated mitral stenosis and serial (>1) left heart obstructive lesions carry the highest risk of maternal cardiovascular events. We are the first to show higher event rates in women with serial left heart obstructive lesions. The data supports the need for specialized and experienced high-risk obstetric-cardiac teams to care for women with left heart obstruction, and demonstrates excellent outcomes in a complex cohort of pregnant women with all types of left heart obstruction.

AIMS: Patients with dextro-transposition of the great arteries (d-TGA) status post atrial switch operation are vulnerable to complications such as baffle leaks. The best noninvasive imaging modality to detect baffle leaks is unknown. The purpose of this study was to determine the sensitivity and specificity of different noninvasive imaging modalities in the detection of baffle leaks in this population. METHODS AND RESULTS: A single center retrospective chart review of atrial switch patients was performed. Sensitivity, specificity, negative predictive value, and positive predictive value for detecting leaks were calculated for transthoracic echocardiogram (TTE) with and without agitated saline, transesophageal echocardiogram (TEE) with and without agitated saline, and cardiac magnetic resonance imaging (cMRI). Studies were included if performed within 1 year of catheterization. Angiography via catheterization was used as the gold standard for the detection of baffle leaks. Fifty-eight atrial switch patients (54 Mustards: four Sennings) from a single pediatric center, undergoing 76 catheterizations, were analyzed. Thirty-nine catheterizations documented a baffle leak. Overall combination of sensitivity and specificity was better in agitated saline studies (TTE: sensitivity 71.4%, specificity 100%; TEE: sensitivity 100%, specificity 92.3%) versus nonagitated studies (TTE: sensitivity 50.0%, specificity 100%; TEE: sensitivity 83.3%, specificity 77.8%; or cMRI: sensitivity 66.7%, specificity 100%). CONCLUSION: TTE or TEE with agitated saline is superior to cardiac magnetic resonance imaging or nonagitated saline TTE and TEE in detecting baffle leaks in atrial switch patients. Agitated saline studies should be performed in this population when looking for baffle leaks.

Atrial switch operations for D-Transposition of the great arteries (D-TGA) were performed until the late 20th century. These patients have substantial rates of re-operation, particularly for baffle related complications. This study sought to analyze the efficacy of percutaneous transcatheter intervention (PTI) for baffle leak and/or stenosis in adult atrial switch patients. Adult patients with a prior atrial switch operation who underwent heart catheterization (2002-2014) at a tertiary adult congenital heart disease referral center were retrospectively analyzed. In 58 adults (30 ± 8 years, 75% men, 14% New York Heart Association (NYHA) functional class ≥2) who underwent 79 catheterizations, PTI was attempted in 50 (baffle leak (n = 10, 20%), stenosis (n = 27, 54%), or both (n = 13, 26%)). PTI was successful in 45 and 5 were referred for surgery due to complex anatomy. A total of 40 bare metal stents, 18 covered stents, 16 occlusion devices, 2 angioplasties, and 1 endovascular graft were deployed. In isolated stenosis, there was improvement in NYHA functional class after PTI (8 vs. 0 patients were NYHA FC > 2, p = 0.004), which was matched by improvement in maximal oxygen consumption on exercise testing (VO2) (25.1 ± 5.4 mL/kg/min vs. 27.9 ± 9 mL/kg/min, p = 0.03). There were no procedure-related deaths or emergent surgeries in this cohort. This single-center cohort is the largest reported series of adult atrial switch operation patients who have undergone PTI for baffle stenosis and/or leak. We demonstrate that PTI with an expert multi-disciplinary team is a safe and effective alternative to surgery in adult patients with an atrial switch operation.

Major adverse maternal cardiovascular-related events (MAMCRE) in aortopathy patients undergoing pregnancy are poorly defined. The aim was to assess for MAMCRE in pregnant patients with aortopathy or aortic enlargement in conotruncal defects (CTD), and determine if there are differences between groups. We conducted a single-center retrospective review of pregnant women (2000-2013) with hereditary vascular disease (HVD: BAV, COA), heritable fibrillinopathies (HF: MFS, EDS, LDS, FTAAS), and CTD with aortic dilatation (TOF, d-TGA, DORV). MAMCRE included: aortic dissection/surgery, therapeutic abortion, change in mode of delivery, and aortic growth > 0.5 cm within 1 year. We identified 73 patients/97 pregnancies (39/50 HVD, 15/20 HF, and 19/27 CTD). There were 14 MAMCRE (14%); 85% (n = 12) occurred in HV and HF patients and was associated with higher baseline cross-sectional-to-height (CSA/Ht) ratio (6.6 [Symbol: see text] 2.5 vs. 5.1 [Symbol: see text] 1.3, p = 0.005). There was more aortic surgery in the HF (vs. HV) (RR 3.9, p = 0.12). Only 2 MAMCRE (aortic growth) occurred in CTD. Overall and emergent C-section was higher than the general population (52% vs. 29%, p < 0.001 and 16% vs. 3%, p < 0.001) as was postpartum hemorrhage (PPH) (6% vs. 1.5%, p < 0.001). We describe the largest series of pregnant women with aortopathy and found a substantial incidence of MAMCRE, which was associated with higher pre-pregnancy CSA/Ht ratio. Rates of C-section and PPH were higher than the general population. Our data suggest that larger, multi-center studies are needed to define risks that predict MAMCRE/obstetric events in women with aortopathies, allowing optimal medical care during pregnancy.
