An atrial myxoma can have a ball-valve effect
that intermittently occludes the mitral valve, leading to the
syncopal episodes. Most pericardial effusions are not large
and do not cause major problems. Large effusions could
lead to tamponade, but this is not an intermittent problem.
Calcification of a bicuspid valve can lead to stenosis with
heart failure, but this condition is progressive. By the time
left atrial enlargement with mural thrombosis and risk of
embolization occurs from mitral stenosis, she should
been symptomatic for years. Coronary artery thrombosis
results in an acute ischemic
