Insights

This case report highlights a successful total artificial heart transplant as a bridge to heart and stem cell transplant for a patient with advanced cardiac amyloidosis. This approach offers a potential lifeline for patients with this severe heart condition.

Area of Science:

  • Cardiology
  • Hematology
  • Transplant Surgery

Background:

  • Cardiac amyloidosis, a complication of light-chain (AL) amyloidosis, affects up to 50% of patients with primary AL amyloidosis.
  • Amyloid cardiomyopathy (CM) historically has a poor prognosis, with 1-year survival rates of 35-40% and heart transplantation considered controversial.
  • The systemic nature of AL amyloidosis and poor survival rates have made cardiac transplantation a challenging option.

Observation:

  • A 47-year-old active duty male presented with atypical chest pain, diagnosed with advanced cardiac amyloidosis.
  • The patient experienced rapidly progressive left ventricular dysfunction, heart failure, and cardiac arrest.
  • He underwent a total artificial heart as a bridge to orthotopic heart and kidney transplantation, followed by autologous stem cell transplant.

Findings:

  • The patient received a total artificial heart, followed by heart and kidney transplantation, and autologous stem cell transplant.
  • He is currently in remission with good functional capacity, able to perform daily activities and moderate exercise.
  • This case demonstrates the feasibility of advanced heart failure management in severe cardiac amyloidosis.

Implications:

  • Modern advancements in chemotherapy and heart failure management are improving outcomes for select AL amyloid CM patients undergoing transplantation.
  • Total artificial heart as a bridge therapy can be a viable option for critically ill patients with advanced cardiac amyloidosis.
  • Ongoing research aims to further improve treatment strategies and outcomes for this life-threatening disease.
