This study is being done to evaluate the impact that monitored anesthetic care (MAC) versus general endotracheal anesthesia (GETA) has on hospital length of stay, rate of ICU admission, or procedural mortality. Also, we hope to determine if the use of Transesophageal Echocardiography (TEE) during GETA impacts device success and durability. Adult patients undergoing transfemoral approach TAVR for aortic valve stenosis may be eligible candidates for this study.

This study is being done to evaluate if there is a significant difference in aortic stenosis grading on Transesophageal echo versus Transthoracic echo. Patients having aortic valve repair may be a candidate for this study.
