Provides preliminary support for retrograde LV catheterization in aortic stenosis; leaves open validation against modern noninvasive methods.
Observational (n=25)
Can retrograde left ventricular catheterization and cardioangiography effectively evaluate the severity and site of obstruction in patients with aortic stenosis?
Retrograde left ventricular catheterization provides a simple means to obtain hemodynamic and angiographic information in patients with aortic stenosis.
Gray et al. (1964) conducted an observational in Aortic stenosis (n=25). Retrograde left ventricular catheterization and cardioangiography was evaluated. Retrograde left ventricular catheterization and cardioangiography was utilized to investigate the severity and site of obstruction in 25 patients with significant aortic stenosis.
