May support operator-independent cardiac output assessment by 3D echocardiography; leaves open prospective validation before clinical adoption.
Does an automated algorithm for 3D transoesophageal colour Doppler echocardiography accurately measure cardiac output compared to thermodilution in patients requiring invasive monitoring?
An automated, operator-independent algorithm for 3D transoesophageal colour Doppler echocardiography provides an objective and reproducible alternative to thermodilution for measuring cardiac output.
Matthews et al. (2010) studied this question.
