|---|
A 59-year-old white male with carcinoid tumor and hepatic metastases underwent hepatic artery embolization. The patient developed carcinoid crisis and a subsequent transthoracic echocardiogram showed classic findings of carcinoid heart disease along with a dilated hypertrophied right ventricle and severely depressed right ventricular ejection fraction. After treatment with octreotide the patient's clinical condition improved and a repeat transthoracic echocardiogram showed a significant improvement and normalization of right ventricular systolic function. Serotonin levels showed a progressive decline that correlated well with the patient's improved clinical condition. These findings suggest that the acute right ventricular dysfunction was secondary to acute carcinoid crisis and resolution resulted in a significant improvement of both right ventricular systolic function and clinical condition.
