Dilatation of the pulmonary vessels of the upper zones and constriction of the vessels of the lower zones characterizes left ventricular decompensation. These changes may precede the onset of clinical symptoms providing a useful warning sign of impending danger. A hypothesis is suggested to account for the non-uniform vessel pattern. An exception is noted in patients with severe emphysema or bronchitis in whom generalized dilatation may occur.
