According to the modified World Health Organization classification, pregnant women with unrepaired aortic coarctation are at very high risk for both maternal and fetal complications and should, therefore, be counselled against pregnancy. The most frequent maternal complications include systemic hypertension, renal failure, preeclampsia, and aortic dissection. Herein, we describe a successful pregnancy in an adult patient with unrepaired aortic coarctation.

Background: Long-term data on COVID-19 vaccine safety, immunogenicity, and acceptance in adults with CHD are lacking., Methods: This is a prospective study including adults with CHD patients undergoing COVID-19 vaccination from January 2021 to June 2022. Data on adverse events, antispike IgG titre, previous or subsequent COVID-19 infection, booster doses, and patients' attitude towards vaccination were collected., Results: Four hundred and ninety CHD patients (36 ± 13 years, 53% male, 94% with moderate/complex defects) were prospectively included: 433 (88%) received a Pfizer-BioNTech mRNA vaccine, 31 (6%) Moderna mRNA vaccine, 23 (5%) AstraZeneca-Oxford ChAdOx1 nCov-19 vaccine, and 3 (0.6%) Janssen Vaccine; 310 (63%) received a booster dose. Median follow-up after vaccination was 1.53 [1.41-1.58] years. No major adverse event was reported. Eighty-two fully vaccinated patients contracted COVID-19 during follow-up after a median of 5.4 [4.3-6.5] months from the last dose. One patient with Ebstein's disease died from severe COVID-19. Symptoms' duration in patients who tested positive after vaccination was significantly shorter than in the group tested positive before vaccination (5.5 [3-8] versus 9 [2.2-15] days, p = 0.04). Median antispike IgG titre measured in 280 individuals (57%) at a median of 1.4 [0.7-3.3] months from the last dose was 2381 [901-8307] BAU/ml. Sixty patients (12%) also showed positive antinucleocapsid antibodies, demonstrating previous SARS-COV2 exposure. Twenty-nine percent appeared to have concerns regarding vaccine safety and 42% reported fearing potential effects of the vaccine on their cardiac disease before discussing with their CHD cardiologist., Conclusion: COVID-19 vaccines appear safe in the mid-term follow-up in adults with CHD with satisfactory immunogenicity and reduction of symptoms' duration in case of infection.

Background: Adults with CHD are known to greatly benefit from a prompt access to continuous expert care. On the other hand, coronavirus disease 2019 pandemic has determined a dramatic worldwide reconfiguration of the healthcare systems, with rapid redeployment of resources towards this emergency. Italy was the first Western country affected by a large-scale spread of coronavirus disease 2019. The aim of our study is to analyse the impact of the coronavirus disease 2019 outbreak on in-hospital care of patients with CHD in an Italian tertiary centre., Methods and Results: We retrospectively reviewed data on CHD hospital admissions in our centre since 1 March, 2020, when the adoption of a strict infection containment policy throughout the country resulted in limited access of patients to routine hospital care and resources reallocation to the care of infected patients. Comparison with data from the previous year was performed in order to identify any relevant differences attributable to the outbreak. Despite cancellation of all elective procedures, the overall number of urgent hospital admission remained stable throughout the period of study. Patients admitted during the pandemic had greater disease complexity (p = 0.001) with longer length of in-hospital stay (p = 0.01). No adverse events or positive swabs were reported among CHD patients who were admitted to hospital or medical personnel caring for these patients., Conclusion: Data from our early experience suggest that coronavirus disease 2019 pandemic did not impact significantly on the provision of urgent care to adult patients with CHD.

Thromboembolic complications occur frequently in Fontan patients with atrial arrhythmias and are a cause of significant morbidity and all-cause mortality. We report the case of an adult woman with direct atriopulmonary connection and atrial arrhythmia who developed a right atrial thrombus. She was switched to apixaban therapy because of echocardiographic evidence of thrombus progression despite combined therapy with warfarin and aspirin. After 1 year of treatment, there was evidence of complete thrombus resolution, in the absence of bleeding events. Our case shows that direct oral anticoagulants can be effective and safe for the treatment of thrombosis in adult patients with complex CHD.

An apparently healthy man of 26 years of age suddenly died. He was known to have had a small ventricular septal defect and complete right bundle branch block from early childhood. At post-mortem examination the small ventricular septal defect was found associated with an aneurysm of the membranous septum. Histological examination showed a normal atrioventricular node and bundle, adjacent to the aneurysm. There was fibrous interruption at the commencement of the right bundle branch, which was considered the basis of the bundle branch block. It was also considered that the right bundle branch block was of the hereditary type and that this, rather than the aneurysm of the membranous septum, was responsible for the unexpected death.
