We present a case of a 68-year-old man with methicillin-susceptible <i>Staphylococcus aureus</i> (MSSA) bacteremia and recurrent fevers, in which multiple echocardiograms failed to detect valvular vegetations. However, an advanced cardiac point of care ultrasound (POCUS) examination identified a vegetation on the aortic valve, later confirmed by TTE and TEE. Although generalization is limited due to operator expertise and patient characteristics, this case demonstrates the utility of advanced cardiac POCUS in diagnosing IE in critically ill patients with negative initial echocardiograms. Incorporating advanced cardiac POCUS into routine diagnostic workflows may improve diagnostic accuracy and patient outcomes. Increasing use of advanced cardiac POCUS also highlights the importance of expanding proficiency among intensivists.</p>","PeriodicalId":74470,"journal":{"name":"POCUS journal","volume":"10 1","pages":"72-77"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12057459/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144043539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to determine the prevalence of systemic venous congestion in recent kidney transplant recipients. We conducted a prospective, longitudinal, descriptive study including 30 adult patients during the first week post-renal transplant at the Instituto de Trasplante y Alta Complejidad in Buenos Aires, Argentina. Venous congestion was detected in 53% of patients (16/30), but only 13.3% (4/30) presented moderate to severe congestion. Pulmonary congestion was more frequent: 70% (21/30) of the patients presented some degree of pulmonary congestion, and 30% (9/30) had moderate or severe congestion. In the venous congestion group, 75% of patients developed delayed graft function (DGF) compared to 57% in the non-congestion group, although this difference was not statistically significant (p<0.3). Body weight and physical examination-two commonly used methods to guide decisions on dialysis initiation and fluid management-were found to be unreliable for assessing the true volume status. In conclusion, venous congestion was observed during the first week following renal transplantation; however, moderate to severe congestion was uncommon, affecting only 13.3% of patients. While DGF was more frequently observed in patients with congestion, a statistically significant association could not be established.

Early diagnosis and treatment are crucial to prevent further cardiac complications and ensure normal childhood growth and development. We discuss the case of a 4-year-old girl diagnosed with cor triatriatum, who was admitted to the emergency room exhibiting symptoms of pneumonia and poor weight gain. A point of care ultrasound (POCUS) test revealed a membrane in the left atrium. The child was admitted and treated for pneumonia and then referred for surgical repair of her heart defect. Following surgery, she was discharged home in stable condition.

Institutionally-supported archiving software can help learners track scan numbers and receive feedback on image acquisition and interpretation. At the University of Saskatchewan, IM residents use POCUS for procedures and assessments but rarely save images, limiting feedback opportunities. Our quality improvement project aimed to increase the number of POCUS images saved by Postgraduate Year One (PGY-1) IM residents, targeting over 75% of non-procedural scans and ensuring over 50% of residents save at least one scan. This quality improvement project was conducted on a clinical teaching unit at an academic hospital over two years. We used four Plan-Do-Study-Act (PDSA) cycles each year to measure the percentage of non-procedural scans saved by PGY-1 IM residents. As a balance measure, we compared the number of scans performed historically and during the study period to monitor for changes in usage. Data was collected using an ultrasound sign-out sheet. At baseline, no diagnostic scans were saved by PGY-1 IM residents. Post-intervention, 56% of scans were archived in cohort one and 76% in cohort two. Additionally, 79% of residents in cohort one and 94% in cohort two archived at least one scan. The balance measure improved from 1.13 in the first year to 2.25 in the second, suggesting image archiving is not a deterrent to performing scans. Through this intervention, we significantly increased the archiving of non-procedural scans by PGY-1 IM residents. We advocate for implementing a formal POCUS archiving system to promote quality assurance in residency programs.</p>","PeriodicalId":74470,"journal":{"name":"POCUS journal","volume":"10 1","pages":"11-18"},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12057454/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144055212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
