<jats:title>Abstract</jats:title><jats:p>Patients undergoing heart transplantation (HTx) with active infection of left ventricular assist devices (LVAD) are at high risk for postoperative infections. Between 2021 and 2022, five (P1–P5) of a total of <jats:italic>n</jats:italic> = 44 patients underwent HTx in our department while suffering from LVAD infection. Postoperatively, patients received adjuvant IgM‐enriched human intravenous immunoglobulin (IGM‐IVIG), consisting of 76% IgG, 12% IgM, and 12% IgA as a novel approach to prevent infective complications. While in P1, P2, and P4, LVAD driveline infection was known before HTx; in P3 and P5, abscess of device pocket was found incidentally during HTx. After a single dose of IGM‐IVIG, all patients showed adequate rise in serum immunoglobulins. In the postoperative course, no patient developed infective complications. All patients were successfully discharged and in good condition at the last follow‐up. Therefore, IGM‐IVIG seems to be an effective adjuvant treatment for patients undergoing HTx with LVAD infections.</jats:p>
