... Ultrasound The left atrial appendage (LAA) is a finger-like projection originating from the main body of the left atrium and the most common site for thrombus formation due to atrial fibrillation (AF) [ 1 ]. Left atrial remodeling due to AF causes LAA dysfunction including contractile dysfunction...

Based on individual ultrasound (US) findings, each subject was assigned to a class of carotid disease severity: 0 (stenosis of the artery lumen <30%), 1...

...Zuojun Wang; Takahiro Fukuda; Takashi Azuma; Hiroshi Furuhata Background: Some studies suggest that low-frequency transcranial ultrasound (LFTUS) can enhance thrombolysis, but other studies suggest that it may have adverse effects on intracranial tissues. We previously reported that LFTUS...

Moreover, details such as microbubble...

... simultaneous c-TCD and c-TEE in 107 patients (321 examinations). We classified all of ultrasound examinations into three groups by size according to microbubbles on c-TEE, such as no PFO (0 microbubble), small PFO (1–29 microbubbles) and large PFO (≥30 microbubbles). We also calculated the number...
