Intracardiac Doppler hemodynamics and flow: new vector, phased-array ultrasound-tipped catheter

Am J Cardiol. 1999 May 15;83(10):1509-12, A9. doi: 10.1016/s0002-9149(99)00136-8.


Comprehensive intracardiac Doppler examination under simultaneous direct ultrasound visualization has not been previously possible. This human feasibility study demonstrates that a new 10Fr, 3.2-mm diameter, 5.5- to 10-MHz frequency agile, phased, vector array, ultrasound-tipped catheter with 4-way tip articulation provides diagnostic, high-quality, intracardiac Doppler signals using pulsed and continuous-wave, color flow, and tissue Doppler.
