This is not a course typical of sarcoidosis although sarcoidosis can have a myriad of presentations. The echocardiogram, thoracic CT scan and echocardiogram are all part of the routine work up for a heart transplant. A repeat of the echocardiogram confirmed that the left ventricular ejection was low at 23%. Pulmonary function testing is below.

Table 1. Pulmonary function testing.

Abbreviations:

• FEV1-forced expiratory volume in the first 1 second of expiration
• FVC-forced vital capacity
• FEV1/FVC-ratio of FEV1 to FVCTLC-total lung capacity
  
• RV-residual volume
  
• DLco-diffusing capacity for carbon monoxide
