Detection of Microembolism Signs using Transcranial Doppler in Infective Endocarditis
Main Article Content
Abstract
Introduction: Transcranial Doppler (TCD) is a rapid, noninvasive, reproducible, and dynamic examination of the intracranial circulation. A unique advantage of TCD is the ability to detect microembolic signals (MES) during monitoring.
Case presentation: We present the case of a 24-year-old man with no significant history or previously identified risk factors.
With a probable diagnosis of infectious endocarditis based on clinical findings. The echocardiogram revealed a bicuspid aortic valve, with a doubtful diagnosis of cardiac vegetation. A diagnosis of endocarditis was made thanks to the support of microembolic signal detection by transcranial Doppler.
Conclusion: The relevance and importance of transcranial Doppler support in infective endocarditis is evaluated. This is a tool that could be considered to be part of the DUKE criteria.
