Myotis 3C Ultrasonic-phonocardiography & conventional phonocardiography

Significantly improved supervision of mechanical heart valve implants Clear discovery of malfunctions Visualization, archiving and long term surveillance of patient data Combined screen representation with conventional phonocardiography Combined screen repesentation with ECG Well suitable for double valve replacement and / or arrhythmia Statistical signal analysis Economic PC system

Modern heart valve implants offer a high reliability and longevity for patients. Nevertheless, cases of heavy thromboses, cerebral TE or other malfunctions are obvserved. Such incidents are even reported from patients with definitely correct compliance of oral anti-coagulation (INR).

The ultrasonic ear of Myotis 3C detects and clearly visualizes a malfunction at an early stage, long before any other method like echocardiography or auscultation detect any suspicious indications. Therefore, the chance of early intervention and conservative drug treatment os clearly increased. Additionally, Myotis 3C is compatible with the patient monitor ThromboCheck.

The exmaple below shows Myotis 3C data of a clinical case, an ultrasound phono of a bileaflet aortic valve at 20kHz.

The chart above shows patient data from the archive where the valve funtion is OK. The chart below shosw data from the same patient, with a clear malfunction and thrombosis. Note the small protosystolic signal! Echocardiography failed in this case.

Myotis 3C offers a combined representation of conventional phonocardiography (1st and 2nd heart sound), ECG and ultrasonic phonocardiography: The temporal correlation of valve signals is clearly possible, also with double valve replacement and arrhythmia. Furthermore, the direct comparison of archived and current patient data discloses even small and gradual changes in the signal profile.
