Key result
Percutaneous left ventricular puncture with catheterization of the aorta was described in 36 attempts to assess pressure gradients and subvalvar stenosis in patients with aortic stenosis.

Does percutaneous left ventricular puncture with catheterization of the aorta allow for accurate assessment of subvalvar stenosis and aortic valve pressure gradients in patients with aortic stenosis?
Percutaneous left ventricular puncture with aortic catheterization provides a method to detect subvalvar stenosis and accurately calculate the systolic pressure gradient across the aortic valve.
Fleming et al. (1958) conducted an observational in Aortic stenosis (n=36). Percutaneous left ventricular puncture with catheterization of the aorta was evaluated. Percutaneous left ventricular puncture with catheterization of the aorta was described in 36 attempts to assess pressure gradients and subvalvar stenosis in patients with aortic stenosis.
