Left Ventricular Decompression by Transaortic Catheter Venting in Extracorporeal Membrane Oxygenation

초록

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been widely applied to patients with cardiogenic shock. Left ventricle (LV) decompression is important when LV distension develops with pulmonary edema. The purpose of this study was to present the results of transaortic catheter venting (TACV) performed during VA-ECMO. We retrospectively reviewed the medical records of 18 patients who underwent both VA-ECMO and TACV between January 2017 and December 2019. Venoarterial extracorporeal membrane oxygenation was applied uneventfully. Lactate level and norepinephrine requirement for patients of weaning success were lower than those of patients of weaning failure after the application of TACV (p = 0.032 and p = 0.015, respectively). The successful weaning rate of ECMO was 77.8% (15/18) and survival rate was 50% (9/18). Transaortic catheter venting may be an easy, safe, and effective technique for LV decompression in patients with VA-ECMO for cardiogenic shock. Also, this technique may be helpful as an alternative or bridge method.
