Fidelity of micromanometer pressure transduction in closed-end angiographic catheters

摘要: Abstract Clinical high fidelity pressure recording has been greatly facilitated by the recent introduction of 2Fr micromanometer-tipped catheters. They can potentially be placed in any structure reached an open-end catheter ≥0.03-inch internal diameter. Because catheters often are not routinely necessary pediatric heart catheterization, we sought to determine whether accurate recordings could obtained from inserted into lumina closed-end angiographic
