A clinical specialist reported that a patient came in intubated with known effusion, and unresponsive.An angiovac tee was placed and heart visualized prior to draping.The material was still present upon investigation.Material was massive in appearance on base of tv with mobile pieces as well.Patient was then prepped and draped in a sterile manner.The rfv and lfv access was obtained with micropuncture and ultrasound guidance.Heparin was given and both sites were upsized respectively.Angiovac primed and inserted into rfv and baseline and threshold flows were established in the ivc/ra junction at roughly 2.7/lpm.The physician advanced the angiovac towards the tv to engage the material.After several passes, tee imaging was then interrogated to see if material was still there.Majority of the material on the tv was removed, so physician moved his focus to material on the septal wall.After engaging material there and clearing area, the patient's spo2 fell to 80.Physician decided to sweep the tv again just to see if he could get any additional material.Anesthesiologist began to manage the low spo2.Physician liked the result and decided to end procedure.Blood in circuit was returned to the patient and all equipment was removed.Hemostasis was achieved on the access sites used.During that time spo2 continued to fall.The physician took fluro of lungs and discovered that the patient had a pneumothorax.A chest tube was placed while patient was on table.The patient's pressure began to decline; therefore, pressors were given to elevate pressure.A respiratory therapist was then called in to help manage airway and patient was transferred to the icu.Physician felt while we were debulking the vegetation on the tricuspid valve, septic spores might have dispersed.The patient is septic and may have congestive heart failure which may have contributed to this event.The device used in association with this event is not available for return to the manufacturer.
