Abstract: The often touted advantages of MR guidance remain largely unrealized for cardiovascular interventional procedures in patients. Many procedures have been simulated in animal models. We argue these opportunities for clinical interventional MR will be met in the near future. This paper reviews technical and clinical considerations and offers advice on how to implement a clinical-grade interventional cardiovascular MR (iCMR) laboratory. We caution that this reflects our personal view of the "state of the art."

The role of cardiovascular magnetic resonance imaging in heart failure.
Theodoros D. Karamitsos,Jane M. Francis,Saul G. Myerson,Joseph B. Selvanayagam,Stefan Neubauer +4 more
TL;DR: The information derived from CMR often reveals the underlying etiology of heart failure, and its high measurement accuracy makes it an ideal technique for monitoring disease progression and the effects of treatment.

TL;DR: This initial study suggests that high-performance low-field-strength MRI offers advantages for MRI-guided catheterizations with metal devices, MRI in high-susceptibility regions, and efficient imaging.

Cardiovascular magnetic resonance.
TL;DR: Cardiovascular magnetic resonance (CMR) creates images using radio waves and magnetic fields to characterize tissues and function of the heart and blood vessels.

Flexible Instruments for Endovascular Interventions: Improved Magnetic Steering, Actuation, and Image-Guided Surgical Instruments
TL;DR: Endovascular interventions employing magnetically actuated surgical catheters deliver the promise of higher accuracy and shorter duration when compared to current, manual techniques, and allow surgeons access to areas of cardiovascular systems that cannot be reached with standard, minimally invasive techniques.
Real-time MRI-guided right heart catheterization in adults using passive catheters

TL;DR: In this early experience, comprehensive transfemoral right heart catheterization appears feasible using only MRI for imaging guidance, and gadolinium-filled balloon catheters were more conspicuous than air-filled ones.

Adaptive sensitivity encoding incorporating temporal filtering (TSENSE).
TL;DR: An adaptive method of sensitivity encoding is presented which incorporates both spatial and temporal filtering and a high degree of alias artifact rejection may be achieved with less stringent requirements on accuracy of coil sensitivity estimates and temporal low‐pass filter selectivity than would be required using each method individually.

On the heating of linear conductive structures as guide wires and catheters in interventional MRI.
TL;DR: A simple analytical approach is presented to address the concern that a long conductive structure couples with the electric field of the radio frequency (RF) transmit coil and induces high voltages near the wire ends.

TL;DR: There seems to be a correlation between the extent of left atrial wall injury and short-term procedural outcome and noninvasive MRI methods that allow for the detection and quantification of LA wall scarring after RF ablation in patients with AF.

TL;DR: It is shown that cardiac catheterisation guided by MRI is safe and practical in a clinical setting, allows better soft tissue visualisation, provides more pertinent physiological information, and results in lower radiation exposure than do fluoroscopically guided procedures.

TL;DR: At 4 weeks after transplantation of SPIO-labeled MSCs, the transplanted cells are not present in the scar and the enhanced MRI signals arise from cardiac macrophages that engulfed the SPIO nanoparticles.
