Abstract Introduction End-stage heart failure due to dilated cardiomyopathy remains a major indication for advanced mechanical circulatory support and heart transplantation. Left ventricular assist devices have emerged as a vital bridge to transplant, improving survival and functional status. However, right ventricular failure following LVAD implantation is a significant and potentially fatal complication, requiring careful management to optimize outcomes. Case presentation We present the case of a 46-year-old male with post-myocarditis dilated cardiomyopathy, severely reduced left ventricular ejection fraction (21%), severe functional mitral and tricuspid regurgitation, and NYHA class IV heart failure. Despite optimal medical therapy, including inotropic support, the patient progressed to multiorgan dysfunction necessitating renal replacement therapy. A HeartMate 3 LVAD was implanted as a bridge to transplantation. The postoperative course was complicated by severe right ventricular failure, requiring prolonged inotropic support and careful hemodynamic management. Despite these challenges, the patient successfully underwent orthotopic heart transplantation. His postoperative evolution was favorable, with stable graft function and good clinical recovery documented during follow-up. Conclusion Right ventricular failure remains a major complication following LVAD implantation, significantly impacting outcomes. While LVADs have revolutionized the management of end-stage heart failure, heart transplantation continues to represent the definitive therapy offering superior long-term survival.
