MR Safety: Cardiac ValvesCan patients with metal heart valves be safely scanned? Read MR Safety Disclaimer Before Proceeding Artificial Cardiac ValvesArtificial cardiac valves may be implanted by either an open surgical or transcatheter approach. They are classified as either bioprosthetic or mechanical....
dysfunctional bileaflet mechanical heart valvedysfunctional BMHVmagnetic resonance imaging techniqueObject We have used a purely phase-encoded magnetic resonance imaging (MRI) technique, single-point ramped imaging with T 1 enhancement (SPRITE), to investigate the steady, turbulent flow dynamics through a...
(INGEVITY+)His Bundle Pacing.These leads have not been evaluated for safety and performance in His bundle pacing; therefore, they are not intended for implantation in the His bundle. Evidence indicates that there is increased risk with His bundle pacing, compared to conventional pacin...
Some ICDs do not have shock leads in the heart. “Leadless” pacemakers are generally placed in the Left atrium Left ventricle Right atrium Right ventricle Which of the following pacemaker scenarios would invoke the greatest MR safety concern?
CONTRAINDICATIONS Unipolar stimulation and impedance-based features are contraindicated for use with the S-ICD System. WARNINGS Concomitant use of the S-ICD System and implanted electro-mechanical devices (for example implantable neuromodulation/neurostimulation systems, ventricular assist device (VAD), o...
Second, the 4D MUSIC technique relies on regularity and adequate control of the respiratory waveform during mechanical ventilation; thus, the image quality will reflect how well both cardiac and respiratory motion artifacts are eliminated. In most patients, if the depth of sedation is adequate and ...
A ventricular assist device (VAD) is used to provide temporary mechanical support for treatment of acute heart failure with the primary goal of producing rapid restoration of the circulation and stabilization of hemodynamics [1, 2]. In 2003, the United States Food and Drug Administration approved ...
