“…One major focus was how to implement new methods in order to acquire real-time non triggered images allowing much more simple and robust imaging as well as permitting the use of CMR to guide percutaneous interventions [13]. Aneja et al demonstrated that real-time CMR using non-optimized sequences with lower spatial and temporal resolution already derives similar results to traditional breath-held images in patients with regular cardiac rhythm [14].…”

The 16th Annual Scientific Sessions of the Society for Cardiovascular Magnetic Resonance (SCMR) took place in San Francisco, USA at the end of January 2013. With a faculty of experts from across the world, this congress provided a wealth of insight into cutting-edge research and technological development. This review article intends to provide a highlight of what represented the most significant advances in the field of cardiovascular magnetic resonance (CMR) during this year’s meeting.

“…Importantly, real-time MRI guidance may also allow for novel approaches to facilitate valve implantation. While preclinical work is promising, including reports of real-time MRI-guided aortic valve replacement, 25 the lack of MR-compatible complex valve delivery systems is an ongoing challenge to translation.…”

Cardiac MR is appealing to guide complex cardiac procedures because it is ionizing radiation free and offers flexible soft tissue contrast. Interventional cardiac MR promises to improve existing procedures and enable new ones for complex arrhythmias, as well as congenital and structural heart disease. Guiding invasive procedures demands faster image acquisition, reconstruction and analysis, as well as intuitive intra-procedural display of imaging data. Standard cardiac MR techniques such as 3D anatomical imaging, cardiac function and flow, parameter mapping and late-gadolinium enhancement can be used to gather valuable clinical data at various procedural stages. Rapid intraprocedural image analysis can extract and highlight critical information about interventional targets and outcomes. In some cases, real-time interactive imaging is used to provide a continuous stream of images displayed to interventionalists for dynamic device navigation. Alternatively, devices are navigated relative to a roadmap of major cardiac structures generated through fast segmentation and registration. Interventional devices can be visualized and tracked throughout a procedure with specialized imaging methods. In a clinical setting, advanced imaging must be integrated with other clinical tools and patient data. In order to perform these complex procedures, interventional cardiac MR relies on customized equipment, such as interactive imaging environments, in-room image display, audio communication, hemodynamic monitoring and recording systems, and electroanatomical mapping and ablation systems. Operating in this sophisticated environment requires coordination and planning. This review will provide an overview of the imaging technology used in MRI-guided cardiac interventions. Specifically, this review will outline clinical targets, standard image acquisition and analysis tools, and the integration of these tools into clinical workflow.

“…The following MR-guided interventions have been performed in animals: aortic coarctation, aneurysm, and dissection repairs [20–22]; atrial septal defect, ventricular septal defect, and patent foramen ovale closures [23, 24, 19]; atrial trans-septal puncture and balloon septostomy [25]; inferior vena cava filter deployment and retrieval [26, 27]; iliac, renal, and carotid artery stenting [28–30]; renal and hepatic embolization [31, 32]; and transcatheter pulmonary artery and aortic valve implantation [33, 34]. Although coronary catheterization and intervention have been described in animals [35, 36], the spatial resolution of MRI compares unfavorably with X-ray fluoroscopy and MR-guided coronary intervention appears unrealistic at present.…”

Interventional cardiovascular magnetic resonance (iCMR) promises to enable radiation-free catheterization procedures and to enhance contemporary image guidance for structural heart and electrophysiological interventions. However, clinical translation of exciting pre-clinical interventions has been limited by availability of devices that are safe to use in the magnetic resonance (MR) environment. We discuss challenges and solutions for clinical translation, including MR-conditional and MR-safe device design, and how to configure an interventional suite. We review the recent advances that have already enabled diagnostic MR right heart catheterization and simple electrophysiologic ablation to be performed in humans and explore future clinical applications.
