Background. Myocardial perfusion scintigraphy has been used by some investigators for the diagnosis of coronary artery disease (CAD) in patients with mild, moderate, and moderate to severe aortic stenosis, with various results. The aim of this study was to assess the safety and diagnostic accuracy o

A new catheter that facilitates catheterization in patients with severe aortic stenosis is described. The catheter design is capable of high-pressure injections for left ventriculography, but it maintains maneuverability and has an end hole for use with a guide wire in traversing tightly stenotic va
## Abstract We describe a series of patients with suspected aortic stenosis who were noted to have a significant aortic valve gradient by Doppler echocardiography but only a minimal gradient during cardiac catheterization. Although the pressure recovery phenomenon partially explained this discrepan
