Evolving Paradigms and Future Frontiers in Heart Transplantation in the Modern Era: a State-of-Art Focus Review.

Heart transplantation stands at the threshold of a new era shaped by transformative advances across the clinical and scientific continuum. This contemporary review highlights developments with the greatest potential to shift practice and improve patients' outcomes. First, evolving strategies in organ preservation and transport, such as ex situ perfusion and normothermic techniques, are expanding geographic boundaries and optimizing donor-heart use. Second, the complex decision-making calculus between heart transplantation and durable left ventricular assist device (LVAD) implantation hinges increasingly on individualized assessments of net survival benefit. Third, the donor pool is being meaningfully expanded through the successful incorporation of hearts from donation after circulatory death (DCD) and hepatitis C virus (HCV)-positive donors, marking a paradigm shift in organ availability. Fourth, the field is witnessing a move toward precision immunosuppression, guided by novel noninvasive biomarkers and surveillance technologies that promise earlier detection of rejection and better immunological control. Fifth, as survival rates improve, attention is turning to the long arc of posttransplant care, addressing late complications, such as cardiac allograft vasculopathy, malignancy, and renal dysfunction, with greater therapeutic insight. Finally, pioneering advances in xenotransplantation signal a bold frontier, with early scientific successes rekindling hopes for overcoming the perennial challenge of organ shortage. Together, these innovations underscore a dynamic and rapidly evolving landscape in heart transplantation-a landscape that demands both clinical adaptability and continued scientific rigor.
