Assessment of left ventricular function is an essential determinant of overall hemodynamics and heart function and therefore of central interest in intra-operative transesophageal echocardiography.
Currently, the most frequently used methods for quantification of left ventricular function are fractional shortening (FS) and fractional area change (FAC).
Radial strain is a new parameter to asses left ventricular function. The investigators want to assess left ventricular function with radial strain, fractional shortening (FS) and fractional area change (FAC) in non-cardiac patients during non-cardiac operations. The aim of this study is to show that radial strain is as reliable as FS and FAC in left ventricular function assessment and more robust to changes in preload and afterload conditions.

TEE (transesophageal echcardiography)
all patients get TEE and all parameters (radial strain, fractional shortening and fractional area change) are evaluated
Procedure: TEE (transesophageal echocardiography)
a TEE is performed in all study objects and all parameters (radial strain, fractional shortening and fractional area change) are analysed
Other Name: radial strain
- left ventricular function [ Time Frame: 3min during TEE ]for left ventricular function transgastric short axis view is recorded 3 times for 3 heart cycles in 3 different positions (zero-position, trendelenburg- and antitrendelenburg-position)
- left ventricular function during changes in loading conditions [ Time Frame: 3min during TEE ]for left ventricular function transgastric short axis view is recorded 3 times for 3 heart cycles in 3 different positions (zero-position, trendelenburg- and antitrendelenburg-position)
