UNASSIGNED: Extracorporeal membrane oxygenation (ECMO) has become one of the often applied mechanical support for acute @entity1455 . During venoarterial (VA) ECMO support, left heart decompression should be considered when left ventricular (LV) distension develops with @entity3126 and @entity1002 . The aim of this study is to report the results of transaortic catheter venting ( @entity35688 ), as an alternative venting method, performed during VA ECMO in @entity1 with acute @entity1455 . We retrospectively reviewed the records of seven @entity1 who underwent both ECMO and @entity35688 between February 2013 and February 2014. ECMO was performed uneventfully, and @entity35688 was introduced under transthoracic echocardiographic guidance in all cases. Hemodynamic parameters, LV ejection fraction and LV end-diastolic dimension (LVEDD) were measured 24 hours after initiating @entity35688 in survivors. There were no procedure-related complications. Four of seven @entity1 (58%) survived. @entity35688 led to an increase in mean blood pressure in all @entity1 (P=0.050). There was a significant difference between pre- and post- @entity35688 -LVEDD (59    14 vs. 50    12 (mm), P=0.044), with a 10% to 23% reduction in LVEDD in survivors. @entity35688 might be an acceptable alternative to venting procedures and useful for LV recovery during VA ECMO in @entity1 with severe @entity1002 .
