Cardiac morphology in lung volume reduction surgery for endstage emphysema.

Lung volume reduction surgery for endstage emphysema produces significant improvements in various pulmonary parameters, but its effects on cardiac morphology and function have not been clearly defined. Ten patients scheduled for lung volume reduction surgery underwent pulmonary function testing, right-heart catheterization, and electron beam computed tomography of the heart. These studies were repeated 12-16 weeks after the procedure.
