What Do AAs Do in Cardiac Anesthesia?
Cardiac anesthesia is the highest-acuity focus area you can pursue as an anesthesiologist assistant. You'll work alongside a cardiac anesthesiologist managing anesthesia for patients undergoing open-heart surgery, valve replacements, CABG, heart transplants, and LVAD implantations. Your role includes placing arterial and central lines, managing Swan-Ganz catheters, titrating vasoactive infusions, coordinating heparin and protamine dosing for cardiopulmonary bypass, and ensuring hemodynamic stability from induction through ICU transport. This is technically demanding, high-stakes work requiring mastery of cardiac physiology and pharmacology.
Your scope in the cardiac OR covers pre-operative cardiac patient assessment, invasive monitoring setup, induction and airway management, anesthesia maintenance during CPB and off-pump surgery, TEE image acquisition support, vasoactive drug management, post-bypass hemodynamic optimization, blood product administration, temporary pacing wire and IABP management, and ICU handoff. You work within the anesthesia care team under anesthesiologist direction throughout every case. The expanding world of structural heart procedures like TAVR and MitraClip, along with mechanical circulatory support devices like LVADs, creates exciting new roles for AAs with cardiac expertise.
