The article, "percutaneous treatment of mechanical mitral valve thrombosis", was reviewed.The article presented a case study of a 75-year-old female patient.It was reported that on an unknown date, a 25mm unknown abbott mechanical mitral valve was implanted.It was later reported on an unknown date, the patient presented with gait instability and dysarthria in the setting of non-adherence to coumadin.Brain magnetic resonance imaging (mri) revealed multiple acute punctate infarcts.Transthoracic echocardiogram (tte) showed severe mitral stenosis with mean gradient of 23mmhg at a heart rate of 87 beats per minute.Fluoro-cine reveled a fixed anterior disc or leaflet.Heparin drip was initiated for presumed thrombosis but the patient condition deteriorated with development of pulmonary edema, hypoxemia, and right ventricular dysfunction.Low dose tissue plasminogen activator, 25 mg of alteplase over 6 h, was administered but the patient developed significant epistaxis with mild reduction in gradient.A decision was made to perform percutaneous intervention.Transthoracic echocardiogram (tee) showed thrombus on both discs with one leaflet completely immobile.A catheter was used to repeatedly push on the immobile leaflet and embolic material was filtered via cerebral protection device placed on the right radial artery.The patient status was reported stable with no neurologic complications post-procedure.The article concluded that percutaneous treatment of mechanical mitral valve thrombosis is feasible and the risk of neurologic complications can be mitigated with the use of a cerebral embolic protection device.[the primary and corresponding author was mamoo nakamura, 127 s san vicente blvd pavilion suite a3600, los angeles, ca 90048, usa, with corresponding email: mamoo.Nakamura@cshs.Org].
