RESUMO

PURPOSE: To report a case of acute macular neuroretinopathy after the vaccination for coronavirus disease 2019. METHODS: A 22-year-old White woman presented with symptoms of paracentral scotomas within a week of receiving coronavirus disease 2019 vaccination. Complete evaluation was performing using multimodal imaging techniques. RESULTS: Spectral domain optical coherence tomography and near-infrared imaging showed characteristic features of acute macular neuroretinopathy. CONCLUSION/DISCUSSION: To the best of our knowledge this is the first reported case of acute macular neuroretinopathy after coronavirus disease 2019 vaccination. Optical coherence tomography angiography did not reveal any signal attenuation, and multifocal electroretinogram and central visual fields were normal indicating that near-infrared imaging and spectral domain optical coherence tomography remain the gold standard in diagnosing this condition especially in smaller lesions.

RESUMO

AIMS: Although systemic embolism is a potential complication in transthyretin amyloid cardiomyopathy (ATTR-CM), data about its incidence and prevalence are scarce. We studied the incidence, prevalence and factors associated with embolic events in ATTR-CM. Additionally, we evaluated embolic events according to the type of oral anticoagulation (OAC) and the performance of the CHA2 DS2 -VASc score in this setting. METHODS AND RESULTS: Clinical characteristics, history of atrial fibrillation (AF) and embolic events were retrospectively collected from ATTR-CM patients evaluated at four international amyloid centres. Overall, 1191 ATTR-CM patients (87% men, median age 77.1 years [interquartile range-IQR 71.4-82], 83% ATTRwt) were studied. A total of 162 (13.6%) have had an embolic event before initial evaluation. Over a median follow-up of 19.9 months (IQR 9.9-35.5), 41 additional patients (3.44%) had an embolic event. Incidence rate (per 100 patient-years) was 0 among patients in sinus rhythm with OAC, 1.3 in sinus rhythm without OAC, 1.7 in AF with OAC, and 4.8 in AF without OAC. CHA2 DS2 -VASc did not predict embolic events in patients in sinus rhythm whereas in patients with AF without OAC, only those with a score ≥4 had embolic events. There was no difference in the incidence rate of embolism between patients with AF treated with vitamin K antagonists (VKAs) (n = 322) and those treated with direct oral anticoagulants (DOACs) (n = 239) (p = 0.66). CONCLUSIONS: Embolic events were a frequent complication in ATTR-CM. OAC reduced the risk of systemic embolism. Embolic rates did not differ with VKAs and DOACs. The CHA2 DS2 -VASc score did not correlate well with clinical outcome in ATTR-CM and should not be used to assess thromboembolic risk in this population.
