Inclusion criteria

Inclusion criteria: - severe aortic stenosis - elective minimal invasive OP (MIC LAT S technique) - normal preoperative EF (>=50%) - normal sinus rhythm - written informed consent to participate

Design outcomes

Primary

Measure	Time frame
Comparability of parameters quantifying the LV function (EF, Strain, Twist and Torsion) in the echocardiographic examination at T1 (intraoperatively, before incision) and T2 (intraoperatively, with valve prosthesis, short before the end of the surgery)	—

Secondary

Measure	Time frame
time to discharge from ICU time to discharge cumulative dosis of catecholamines time to extubation rate of Major Adverse Cardiac Events 30-days and 1-year mortality	—
