[Lung perfusion distribution study by means of 133Xe]. 1979

P Ebavý, and A Oppelt, and V Stanek, and I Vidimski

A method for studying regional lung perfusion employing 133Xe is described. Simple radioisotope apparatus with two catheters was used; every isotopic diagnostic department is equipped with it. The possibility of the clinical use of this method was demonstrated in 28 patients with mitral stenosis and in 11 healthy persons. A statistically significant dependence between regional movement of the perfusion to the upper regions of the lungs and the degree of hemodynamics changes in mitral stenosis was noted. Study of the distribution of persusion may be used as a simple method for appraising the hemodynamic changes in mitral stenosis. This method is simple and not burdensome for the patient. It may be recommended first of all in repeated examinations and long-term observations over patients.

UI	MeSH Term	Description	Entries
D006976	Hypertension, Pulmonary	Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.	Pulmonary Hypertension
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D008946	Mitral Valve Stenosis	Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
