Predominant Right Ventricular Dysfunction in Cardiac Sarcoidosis.

ABSTRACT:

Background

Clinically significant cardiac sarcoidosis is rare, seen in 5% of patients with sarcoidosis. Predominant right ventricular (RV) dysfunction is seen even less often.

Case summary

A 59-year-old man presented to the emergency department from his outpatient cardiologist's office with high-grade atrioventricular block and signs of right-sided heart failure. Transthoracic echocardiogram showed normal left ventricular systolic function, with severe RV enlargement and dysfunction. Right heart catheterization revealed mild postcapillary pulmonary hypertension and disproportionate RV dysfunction. A transbronchial biopsy of mediastinal lymph nodes showed noncaseating granulomas, consistent with sarcoidosis.

Discussion

RV dysfunction in sarcoidosis is most often second
