Fifty-three patients (11.8%) on VA-ECMO required LV unloading. Percutaneous balloon atrial septostomy (PBAS), intra-aortic balloon pump (IABP) and transapical LV vent (TALVV) strategies were compared with regards to the composite rate of death, procedure-related complications and neurological complications. The secondary outcomes were reduced pulmonary capillary wedge pressure, pulmonary artery pressure, central venous pressure, left atrial diameter and resolution of pulmonary oedema on a chest X-ray within 48\u2009h.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>No death related to the LV unloading procedure was detected. Reduction in pulmonary capillary wedge pressure was highest with the TALVV technique (17.2\u2009\u00b1\u20092.1\u2009mmHg; P\u2009&amp;lt;\u20090.001) and was higher in the PBAS than in the IABP group; the difference was significant (9.6\u2009\u00b1\u20092.5 and 3.9\u2009\u00b1\u20091.3, respectively; P\u2009=\u20090.001). Reduction in central venous pressure with TALVV was highest with the other procedures (7.4\u2009\u00b1\u20091.1\u2009mmHg; P\u2009&amp;lt;\u20090.001). However, procedure-related complications were significantly higher with TALVV compared to the PBAS and IABP groups (50% vs 17.6% and 10%, respectively; P\u2009=\u20090.015). We observed no significant differences in mortality or neurological complications between the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Our results suggest that TALVV was the most effective method for LV unloading compared with PBAS and IABP for VA-ECMO support but was associated with complications.
