title: [Vectorcardiographic evolution after a valve replacement operation].
abstract: The vectorcardiograms of 35 patients with valvular heart disease were recorded before and after prosthetic valve replacement. The spatial magnitude of the 40 msec and maximum QRS vectors were decreased postoperatively in patients with mitral insufficiency aortic stenosis and aortic insufficiency. 9 patients were studied postoperatively by right heart catheterization.
