Pulmonary Blood Volume and Pulmonary Capillary Blood Volume in Valvular Heart Disease

Pulmonary Blood Volume and Pulmonary Capillary Blood Volume in Valvular

Measurements of pulmonary blood volume (PBV) and pulmonary capillary blood volume (V,) 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 fr...

Pulmonary Blood Volume in Congestive Heart Failure

IN ANALYZING the clinical and hemodynamic features of congestive heart failure due to myocardial disease or associated with mitral stenosis, many authors indicate or clearly imply that a significant augmentation in pulmonary blood volume plays a major role in the pathogenesis of pulmonary congestion and edema.'-6 These conclusions have depended largely upon indirect evidence such as clinical ev...

Radionuclide determined pulmonary blood volume in ischaemic heart disease.

Most measurements of pulmonary blood volume have been based on the Stewart-Hamilton dye dilution principle and have required direct catheterisation of the cardiac chambers. Alternatively a precordial counter may be used to detect the composite right and left heart curves after an intravenous injection of radionuclide. We investigated the use of a gamma camera/computer system to determine the ra...

The alveolar-capillary membrane diffusing capacity and the pulmonary capillary blood volume in heart transplant candidates.

OBJECTIVES To determine the mechanism of impairment of pulmonary transfer factor for carbon monoxide (TL(CO)) in heart transplant candidates, as this is the most common lung function abnormality. SETTING Regional cardiopulmonary transplant centre. METHODS TL(CO) and its components (the diffusing capacity of the alveolar-capillary membrane (D(M)) and the pulmonary capillary blood volume (V(C...
