Abstract:
Although echocardiography remains the key tool for evaluation of aortic valve stenosis severity, in a fair minority of patients invasive evaluation is still needed. Dual-lumen catheters allow for simultaneous trans-aortic pressure measurements with single arterial access. We describe a technique where traditional hardware using non-dedicated catheters can be used to obtain simultaneous pressure measurements using a 6 French single arterial access.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
