Successful treatment of drug-induced esophageal ulcer in a patient with chronic heart failure: A case report
RATIONALE: Although esophageal compression due to cardiomegaly may be a risk factor of drug-induced esophageal injuries (DIEIs), the causal relationship between the two conditions has not been fully demonstrated.

Sumario: | RATIONALE: Although esophageal compression due to cardiomegaly may be a risk factor of drug-induced esophageal injuries (DIEIs), the causal relationship between the two conditions has not been fully demonstrated. PATIENT CONCERNS: We present a case of a drug-induced esophageal ulcer caused by left atrial enlargement in a 44-year-old woman with end-stage hypertrophic cardiomyopathy. Upper gastrointestinal endoscopy showed a deep, circumferential ulcer in the middle thoracic esophagus. CT revealed that the esophagus was compressed between the enlarged left atrium (LA) and the vertebral body. In the upper gastrointestinal series, retention of contrast media was observed in the esophagus near the LA. DIAGNOSIS: The ulcer was a result of potassium chloride retention in the esophagus, which was compressed by the enlarged LA. INTERVENTION: After cessation of potassium chloride administration for 2 months, the ulcer healed and a stricture developed. Two years after the ulcer development, the patient underwent heart transplantation, and subsequent endoscopic balloon dilation was performed for the esophageal stricture. OUTCOMES: The patient's oral intake recovered completely without any ulcer recurrence. LESSONS: The case demonstrated that esophageal compression by the enlarged LA caused a drug-induced esophageal ulcer. Preventive care and treatment measures for DIEIs, including an anatomical approach, should be considered for patients with LA enlargement. |
