cardiopulmonary bypass

does cardiopulmonary bypass diminish left ventricular function?
do multiple entries into the chest cavity cause a degree of restriction and fibrosis of the myrocardium?
what is the proper placement of the swan-ganz catheter during open heart
surgery?
if the phrenic nerve were severed during a side entry would there be an immediate response of the diaphram? if so, would this cause any additional difficulty or risk to reach the heart?
if the swan-ganz were mistakenly placed in the superior vena cava and entrapped by suture could it be freed via mediastinal exploration thru median sternotomy incision without use of bypass pump? would the lack of
its use cause any further complications or risks?
