Cardiac Point-of-Care Ultrasound for the Diagnosis of Infective Endocarditis in a Patient with Non-Specific Rheumatologic Symptoms and Glomerulonephritis. Academic Article uri icon

Overview

abstract

  • BACKGROUND Point-of-care ultrasound (POCUS) is performed at the bedside by a healthcare professional who is directly caring for the patient. Subacute infective endocarditis can be challenging to diagnose, as patients often present with non-specific symptoms. The modified Duke criteria include echocardiographic findings as a major criterion, but the role of POCUS has not been established. This report is of a case of infective endocarditis diagnosed using POCUS. CASE REPORT A 57-year-old man was admitted to hospital with a presumptive diagnosis of rapidly progressive glomerulonephritis secondary to vasculitis associated with a non-specific rheumatologic condition that had developed during the previous three months. Several specialist physicians had previously examined him. On hospital admission, POCUS was performed by the internal medicine physician, which showed mitral valve endocarditis resulting in a change in clinical management from steroid therapy to antibiotic therapy. Blood cultures were performed, which grew Streptococcus mutans. CONCLUSIONS To our knowledge, this is the first reported case of infective endocarditis diagnosed by an internist using POCUS in a patient admitted to hospital with an alternative diagnosis and management plan in place. This case highlights the potential role of POCUS in the acute hospital setting and supports the need for studies to compare the diagnostic performance of POCUS with transthoracic echocardiography for the detection of valvular vegetations. POCUS may be considered for patients with a possible diagnosis of infective endocarditis that cannot be excluded using the modified Duke criteria, potentially resulting in earlier diagnosis and management, with an improved clinical outcome.
