•1) Patients scheduled to undergo elective aortic valve replacement due to significant aortic valve stenosis, defined by an aortic valve area of <1 cm², and concordingly left ventricular hypertrophy, defined by an interventricular septum thickness > 11 mm on echocardiography.
•2) Patients undergoing coronary artery bypass surgery suffering from compromised left ventricular function, defined by a left ventricular ejection fraction of < 45% on preoperative echocardiography
•3) written informed consent

•Preoperative exclusion criteria include: intracardiac shunts, more than trivial regurge of the mitral valve or tricuspid valve and patients with any degree of mitral valve stenosis.
