Complete Heart Block After Low Dose Octreotide Infusion for Esophageal Variceal Bleeding

Area of Science:

• Gastroenterology and Hepatology
• Cardiology

Background:

• Cirrhosis and chronic liver disease lead to portal hypertension, causing complications like esophageal varices.
• Esophageal varices can rupture and bleed, posing a critical risk in liver failure patients with coagulopathy.

Observation:

• A patient with decompensated liver failure for transplant experienced severe, refractory gastrointestinal bleeding.
• The patient was treated with an octreotide infusion to reduce portal pressures and splanchnic blood flow.

Findings:

• Following octreotide infusion, the patient developed complete heart block.
• This case suggests a potential link between octreotide and cardiac conduction abnormalities.

Implications:

• Understanding the cardiac mechanisms of octreotide is crucial for managing medically complex patients.
• This case underscores the importance of vigilant cardiac monitoring during octreotide therapy in liver disease patients.
