This investigator initiated, prospective, observational, single-center study is designed to assess whether dynamic monitors of cardiac function, such as stroke volume variation (SVV), that have been shown to predict volume responsiveness differ in clinical utility between patients with and without diastolic dysfunction.~Specific Aims:~Determine the threshold for the predictive response of SVV with respect to increasing cardiac output for patients with and without diastolic dysfunction.~Compare the trans thoracic ultrasound assessment of left ventricular diastolic function before and after the induction of general anesthesia.
