Does transesophageal echocardiography improve the diagnosis of periannular complications in patients with infective endocarditis compared to transthoracic echocardiography?
Transesophageal echocardiography is essential for the comprehensive preoperative diagnosis of periannular complications in infective endocarditis, especially when transthoracic echocardiography underestimates disease severity.
Despite its current limitations transthoracic echocardiography is still widely used for the anatomical and functional evaluation of patients with infective endocarditis. However, all these limitations can be overcome by using transesophageal echocardiography. We present the case of a 42-year-old male patient, diagnosed with aortic valve infective endocarditis, whose transthoracic echocardiography showed only a cusp vegetation and aortic regurgitation, but raised the suspicion of periannular complications. The transesophageal echocardiography revealed a circular aortic root abscess and a ventricular septal defect with left-to-right shunt, and consequently leads to a complete different surgical tactical approach. The patient was urgently referred for surgery due to the rapid deterioration of the hemodynamic status, and had a good outcome on the short-term follow-up.
