[Cardiac resynchronization therapy in non-ischemic cardiomyopathy]

Area of Science:

• Cardiology
• Transplantation Medicine
• Infectious Diseases

Background:

• Advanced heart failure often requires advanced therapies beyond pharmacologic treatment.
• Non-ischemic cardiomyopathy can develop or be exacerbated by various factors, including viral infections and post-transplant complications.
• Cardiac resynchronization therapy (CRT) is indicated for specific heart failure patients with systolic dysfunction and conduction delays.

Observation:

• A patient with a history of liver transplantation experienced progressive congestive heart failure.
• The heart failure was attributed to non-ischemic cardiomyopathy, potentially linked to hepatitis C reactivation post-transplant.
• Standard pharmacologic therapy for heart failure yielded an insufficient clinical response.

Findings:

• The patient presented with severe systolic dysfunction and a wide QRS complex, meeting criteria for CRT.
• Successful treatment with cardiac resynchronization therapy (CRT) was achieved.
• CRT significantly improved the patient's heart failure symptoms and condition.

Implications:

• This case highlights the potential benefit of CRT in complex heart failure scenarios, including those arising after organ transplantation.
• It underscores the importance of considering cardiac complications in post-transplant patients, especially with underlying viral hepatitis.
• Cardiac resynchronization therapy (CRT) may be a viable option for non-ischemic cardiomyopathy refractory to medical management.
