Optimizing outcomes in heart transplantation: multidisciplinary Heart Teams and mechanical circulatory support for primary graft dysfunction

Heart transplantation (HTx) is a definitive treatment for selected patients with advanced heart failure. However, primary graft dysfunction (PGD), a severe early complication, is a major cause of post-HTx morbidity and mortality. This paper explores the pathophysiology, diagnostic approaches, and management strategies for PGD, with a particular focus on temporary mechanical circulatory support (MCS) devices such as venoarterial extracorporeal membrane oxygenation and Impella. It also highlights the essential role of the multidisciplinary Heart Team in optimizing outcomes through patient-tailored MCS selection and timely intervention.
