Abstract
Perfusion lung scan using-⁹⁹ ͫTc-MAA was performed in 18 patients with mitral valve disease before and after valve surgery and 10 normal subjects. The ratio of ⁹⁹ ͫTc-MAA distribution per unit of lung volume in the upper third of the right lung to that in the lower third, designated "U/L ratio" was calculated and taken to represent the ratio of blood flow in these two regions. In 10 normal subjects in whom ⁹⁹ ͫTc-MAA was infused in the supine position, U/L ratio averaged 1.11±0.24, indicating essentially uniform distribution. Preoperative U/L ratio in the 18 patients with mitral valve disease averaged 2.29±0.67, a valve which was significantly greater than normal. U/L ratio after surgical correction fell from preoperative value 2.29±0.67 to 1.71±0.44 three months postoperatively but still higher than that of the normal subjects.
