Objective
To investigate the safety of a novel, miniaturized, monoplane transesophageal echocardiography
probe (mTEE) and its potential as a hemodynamic monitoring tool.
Design
This was a retrospective analysis of the clinical evaluation of a disposable mTEE
in ventilated patients with severe cardiogenic shock requiring hemodynamic support.
mTEE assessment was performed by operators with mixed levels of TEE training. Information
on hemodynamic interventions based on mTEE findings was recorded.
Setting
A tertiary university cardiac critical care unit.
Participants
Male and female critical care patients admitted to the unit with severe hemodynamic
instability.
Interventions
Insertion of miniaturized disposable TEE probe and hemodynamic and other critical
care interventions based on this and conventional monitoring.
Measurements and Main Results
In 41 patients (51.2% female, 73.2% after cardiac surgery), hemodynamic support probe
insertion was accomplished without major complications. A total of 195 mTEE studies
were performed, resulting in changes in therapy in 37 (90.2%) patients based on mTEE
findings, leading to an improvement in hemodynamic parameters in 33 (80.5%) patients.
Right ventricular (RV) failure was diagnosed in 25 patients (67.6%) and mTEE had a
direct therapeutic impact on management of RV failure in 17 patients (68 %).
Conclusions
Insertion and operation of a novel, miniaturized transoesophageal echocardiography
probe can be performed for up to 72 hours without major complications. Repeated assessment
using this device provides complementary information to invasive monitoring in the
majority of patients and has an impact on hemodynamic management.
