Study Summary

The study proposes to develop a phenylephrine protocol to be used during transesophageal echocardiography, whereby intravenous phenylephrine would be used to increase afterload with the intent to mimic the awake hemodynamic profile and variation that occurs with normal physical activity. The expectation is to see changes in severity of Mitral Regurgitation (MR) grade with increasing afterload, which in turn can provide more accurate quantification of MR severity to assist in clinical decision making.

Primary Outcome

The purpose of this study is to compare the echocardiographic parameters of MR grade before and after the use of phenylephrine during transesophageal echocardiography (TEE) and to document an increase in echocardiographic parameters of MR grade after the use of phenylephrine.
