Medtronic received information that during the implant of this transcatheter pulmonary bioprosthetic valve, into a patient with single ventricle physiology that had severe mitral stenosis and a small left ventricle cavity with good systolic function, it was reported the valve implant was uneventful however the left ventricle was unable to handle the loading conditions.Acute systolic dysfunction, marked elevation in diastolic pressure, signs of ischemia, and hemodynamic impairment were noted.The valve was surgically removed and the patient was restored to single ventricle physiology.No further adverse patient effects were reported.
