Event Description

Medtronic received information that during the surgery to implant this 25mm pulmonary valved conduit, bleeding was noted on the suture lines.The patient was placed back on cardiopulmonary bypass (cpb) and the suture lines were reinforced.After removal from cpb, bleeding was present again.Cpb was re-initiated and the areas were reinforced with more sutures.Then, the patient weaned from cpb without difficulty and without significant residual bleeding.At the conclusion of the procedure, atrial fibrillation (afib) and atrial flutter were present.The patient was successfully cardioverted and sent to the intensive care unit (icu) in stable condition.In the immediate post operative period the patient developed "brisk, sanguineous" output from the mediastinal and pleural drains.The patient was hypotensive.Atrial flutter occurred again, and the patient was unable to be paced with the temporary pacing wires,but spontaneously corrected to normal sinus rhythm.A second atrial flutter episode was successfully treated with external pacing.A third arrhythmia episode however required 1 minute of cardiopulmonary resuscitation (cpr), epinephrine and defibrillation.At that time the patient's chest was re-opened and the temporary pacing wires were repositioned.No active bleeding was noted, and the chest was irrigated.The patient's chest was left open.The patient remained clinically stable, and two days later, the patient's chest was successfully closed.Approximately two weeks post conduit implant, persistent left pleural effusions and a retained hemothorax were present.A thoracoscopy was performed to evacuate the hemothorax.In total, approximately 2 l of "old blood" and pleural debris were removed.The patient tolerated the procedure well with clinical improvement.He was discharged 7 days later with no additional adverse patient effects.
