Temporary circulatory support with surgically implanted microaxial pumps in postcardiotomy cardiogenic shock following coronary artery bypass surgery

ObjectivesPatients with ischemic cardiomyopathy undergoing coronary artery bypass grafting (CABG) surgery may develop postcardiotomy cardiogenic shock. In these cases, implantation of an Impella 5.0 or 5.5 microaxial pump offers full hemodynamic support while simultaneously unloading the left ventricle.MethodsPreoperative, perioperative, and postoperative data all patients receiving after CABG between September 2017 October 2022 were retrospectively collected. Cohort built-up was performed according to timing implantation, either simultaneous during delayed.ResultsA total n = 42 received support, whom 27 underwent 15 delayed therapy. Preoperative ventricular ejection fraction similarly low in both groups (26.7 ± 0.7% vs 24.8 11.3%; P .32). cohort, a median 1 (1; 2) days surgery. Survival 30 (75.6% 47.6%, .04) year (69.4% 29.8%, .03) better cohort implantation.ConclusionsThe combined advantages LV pumps lead favorable survival failure following Early initial shows trend toward more as compared support.
