Your doctor can enter the pericardial space with a needle and then use a small tube (catheter) to drain fluid â a procedure called pericardiocentesis. The doctor will use imaging devices â either echocardiography or a type of X-ray technology called fluoroscopy â to guide the work. An ECG machine monitors your heart during the procedure. In most cases, the catheter will be left in place to drain the pericardial space for a few days to help prevent the fluid from building up again. Open heart surgery.
