Why the study?
What are the pulmonary blood volume and pulmonary capillary blood volume in patients with valvular heart disease compared to normal subjects?
What are the pulmonary blood volume and pulmonary capillary blood volume in patients with valvular heart disease compared to normal subjects?
The study provides baseline measurements of pulmonary blood volume and pulmonary capillary blood volume in normal subjects and patients with valvular heart disease.
Provides normative pulmonary blood volume and capillary volume ranges; leaves open their diagnostic utility in valvular disease.
Measurements of pulmonary blood volume (PBV) and pulmonary capillary blood volume (V c ) and hemodynamic studies were made in a series of 106 patients with valvular heart disease (62 with predominant mitral lesions and 44 with predominant aortic lesions). The results were compared with the data obtained from 14 "normal" patients and nine normal subjects. In 14 "normal" patients, the PBV varied from 204 to 315 ml/m 2 with a mean value of 269 ml/m 2 , while in nine "normal" patients and nine normal subjects the V c ranged from 39 to 66 ml/m 2 with a mean value of 54 ml/m 2 .
