Introduction:
This simulation on cardiac tamponade and complete heart block in the context of severe aortic stenosis presents the learner with a rare (cardiac tamponade) and a common (complete heart block) complication in the intraoperative setting of transfemoral aortic valve implantation in a high-fidelity, low-risk simulation environment. Based on an amalgam of index cases, the simulation was developed to address a recognized area of need for cardiothoracic anesthesia scenarios in the simulation curriculum of our home institution.
Methods:
The simulation case file covered the case narrative, learning objectives, a summary of critical actions performed, and supplemental figures needed to complete the educational activity. A high-fidelity patient simulator, an anesthesia machine, monitors, and a computer capable of displaying standard computer slide presentation software and movie files provided the optimal environment for simulation.
Results:
Fifteen anesthesia residents experienced the simulation over the 2016-2017 and 2017-2018 academic years. The trainees who experienced this simulation improved their understanding of tamponade hemodynamic pathophysiology and recognition of hemodynamically unstable bradycardia.
Discussion:
This case has been an effective addition to the repertoire of simulation scenarios at the University of Iowa and has been incorporated into the general curriculum of simulation cases for mid-training junior and senior anesthesia residents.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Physiology of the Heart: The Cardiac Cycle
Diastole: The Relaxation Phase
During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
