Real-time MRI-guided right heart catheterization in adults using passive catheters.
AIMS Real-time MRI creates images with superb tissue contrast that may enable radiation-free catheterization. Simple procedures are the first step towards novel interventional procedures. We aim to perform comprehensive transfemoral diagnostic right heart catheterization in an unselected cohort of patients entirely using MRI guidance. METHODS AND RESULTS We performed X-ray and MRI-guided tran...
متن کاملToward MRI-guided coronary catheterization: visualization of guiding catheters, guidewires, and anatomy in real time.
The success of x-ray fluoroscopy-guided coronary catheterization depends in part on the ability to obtain simultaneous and real-time visualization of the guidewire, guiding catheter, and anatomy of the chest. The hypothesis explored in this paper is that magnetic resonance imaging (MRI) could provide this ability. This hypothesis was tested with loopless antennas used as the guidewire and a gui...
متن کاملPassive Tracking In Vivo Cardiovascular Catheterization Under Real-Time MRI Guidance Using Conventional X-ray Angiographic Catheters
S. Zhang, S. Rafie, Y. Chen, C. Hillenbrand, J. L. Duerk, J. S. Lewin University Hospitals of Cleveland, Case Western Reserve University, Cleveland, OH, United States Introduction According to the American Heart Association, more than 1.3 million cardiovascular catheterizations are performed annually in the USA for diagnostic or interventional therapeutic purpose. To date, x-ray fluoroscopy rem...
متن کاملMR guided right heart catheterization - the NIH experience
Background Realtime MR enables radiation free guidance for right heart catheterization (RHC). In addition to catheter navigation for sampling of invasive pressures and blood oxygen saturations, MR permits concomitant assessment of cardiac chamber volumes and cardiac output with phase contrast flow measurements. By performing repeat measurements under different physiological provocations (e.g. s...
متن کاملReal-time magnetic resonance imaging-guided coronary catheterization in swine.
BACKGROUND We tested the hypothesis that real-time magnetic resonance imaging (MRI) can guide coronary artery catheterization in swine via a percutaneous femoral artery approach. METHODS AND RESULTS In 12 pigs, we accessed femoral arteries percutaneously. We used 6- or 7-French coronary Judkins catheters filled with dilute 4% gadolinium (Gd) contrast agent and coaxially inserted 0.030-inch di...
