An attempt to place an 8 mm septal occluder was undertaken to stop the blood flow through the main pulmonary artery.Difficulty was encountered with getting the device to deploy properly from the left femoral vein approach.An attempt was made to retract the device, but difficulty was encountered while pulling the device back into the delivery system and the femoral approach was abandoned.The access was converted to the right internal jugular vein for the attempted delivery of a 14 mm amplatzer muscular vsd occluder (muscvsd).Proper placement could not be achieved and upon pulling the device into the delivery system, the device wedged and was unable to be used.A third attempt with a closure device was abandoned as proper positioning could not be achieved of the delivery sheath (12 mm x 10 mm).Due to the extended length of anesthesia and exhaustion of delivery options no further attempts were undertaken.
