Manual versus automated heart strain measurement during cardiac surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study compares conventional manual myocardial strain analysis with fully automated strain software performed on transesophageal echocardiography (TEE) images during adult cardiac surgery. Analyses are done using GE Vivid systems (S60, S70, E95) with EchoPAC and TOMTEC software to directly compare time required and agreement between methods. The study enrolls adult cardiac surgery patients in sinus rhythm without severe valvular regurgitation and excludes cases with poor image quality or mechanical circulatory support. The goal is to determine whether automated strain provides reliable intraoperative measurements fast enough to be clinically useful.
