title: The prevention of circulatory collapse in left atrial myxoma or left atrail thrombus patients.
abstract: Some patients with myxoma or thrombus may develop to severe hypotension or sudden death. In this article, we hypothesize a clinical scenario that when the myxoma or thrombus blocks in the mitral valve and causes significant hypotension during anesthesia or surgery. Increasing cardiac preload will be an effective preventive method to increasing the mitral valve annulus and decreasing the severity of stenosis, as a result it will prevent circulatory collapse. Our hypothesis will decrease the possibility of lethal mitral valve stenosis induced by left atrial mass blocking the mitral valve area. In addition, we should also maintain a relative slow heart rate and a relative high systemic vascular resistance.
