This review aimed to assess the prevalence of structural\/functional deviations in echocardiography in individuals with PCC compared to patients without PCC. Methods: We searched three databases. Two reviewers independently screened articles using LASER Al and extracted relevant data using a piloted Excel sheet. We performed meta-analysis using OpenMeta and RevManWeb and a subgroup analysis based on patients\u2019 settings during acute COVID-19. We assessed the risk of bias using the Hoy et al. tool and the certainty using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Results: We included 16 studies that reported on differences in echocardiographic findings in patients with or without PCC. Individuals with PCC were more likely to have structural\/functional deviations in echocardiographic readings of unclear clinical significance, particularly those who were hospitalized during acute COVID-19. The overall certainty of the evidence was very low due to the high risk of bias, indirectness, and imprecision. Conclusions: This review provides insight into the use of echocardiograms and the frequency of test deviations in individuals with PCC. Despite existing evidence, there is a need for future studies to assess the diagnostic test accuracy of echocardiograms in PCC.<\/jats:p>","DOI":"10.3390\/jcm15124643","type":"journal-article","created":{"date-parts":[[2026,6,16]],"date-time":"2026-06-16T00:49:01Z","timestamp":1781570941000},"page":"4643","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Echocardiogram
