Suicide left ventricle following protamine: A case report

Abstract

AbstractA patient with severe aortic stenosis and left ventricular hypertrophy underwent a transcatheter aortic valve replacement. The patient's blood pressure significantly dropped after protamine administration. A diagnosis of suicide left ventricle post‐valve replacement was made. The diagnosis and management of the protamine reaction are detailed. This case highlights the need to slowly infuse protamine sulfate and monitor for adverse events.
