C.3. How would you monitor this patient with severe AS and MR?
Answer:
In addition to the standard ASA monitors, the patient should have a radial artery (pre-induction) and a PA catheter (typically post-induction). Following induction of anesthesia and endotracheal intubation, a TEE probe is usually inserted to confirm the valvular pathology and to assess ventricular function. Following valve replacement, the TEE probe can be used to check for adequacy of valvular function and absence of paravalvular leaks, and to assess post-bypass ventricular function.
