Overview
This session will review clinical needs and technical developments for cardiac MR in pediatric and congenital heart disease. Sessions will focus on fetal cardiac MR, interventional cardiac MR, cardiac MR in patients with devices, and when contrast is needed for pediatric and congenital heart disease cardiac MR.

Target Audience
Students, technologists, researchers, clinicians.

Educational Objectives
As a result of attending this course, participants should be able to:
- Determine when fetal cardiac MR is needed;
- Describe which sequences are used for fetal cardiac MR;
- Describe which sequences are used for interventional cardiac MR;
- Summarize when interventional cardiac MR is appropriate;
- Review how to optimize cardiac MR sequences in patients with cardiac devices;
- Review techniques for minimizing artifacts from coils, stents, and other metallic devices in pediatric and CHD patients; and
- Determine when contrast is needed or not in pediatric and congenital heart disease CMR.
    Fetal Cardiac MR
13:00   Clinical Need & Experience with Fetal CMR Mike Seed
13:25   Current & Future Fetal CMR Techniques Chris Macgowan

Keywords: Cardiovascular: Cardiac, Cardiovascular: Blood, Image acquisition: Motion correction

In this presentation, I summarize recent advances in fetal cardiovascular MRI and discuss potential directions for the field. A wide range of topics will be introduced including dynamic cardiac imaging, flow quantification, and blood oximetry. The techniques that support such work will also be discussed including fast imaging, motion compensation, novel gating strategies, and volumetric reconstruction.
    Interventional CMR in Pediatric & Congenital Heart Disease
13:50   Technical Developments Enabling iCMR for Congenital Heart Disease Sébastien Roujol
14:15   Clinical Applications for iCMR in Congenital Heart Disease Suren Reddy
    Pediatric & Congenital Heart Disease CMR in Patients with Devices
14:40   Cardiac MR in Patients with Cardiac Devices Margaret Samyn

Keywords: Cardiovascular: Cardiac, Transferable skills: Safety, Cross-organ: Pediatric

“Cardiac MRI in Patients with Devices” will discuss the current state of magnetic resonance imaging for patients with implanted devices – focusing on pacemakers. Pediatric specific data will be reviewed, as will Heart Rhythm Society guidelines for imaging adults with devices.
15:05   Break & Meet the Teachers
 
15:30   Minimizing Artifacts in Patients with Coils, Stents & Other Metallic Devices Lindsay Griffin

Keywords: Cardiovascular: Cardiovascular, Cross-organ: Pediatric, Image acquisition: Artefacts

We will discuss mitigation of metallic artifact in cardiac and pediatric magnetic resonance imaging (MRI). We will develop a checklist for exam planning that considers patient, machine, and sequence factors. We will review examples of common instigators of metal artifact, including those outside the field of view like braces, tracheostomies, and gastrointestinal clips as well as those in the chest like ductus arteriosus clips, spinal fusion hardware, and coils of AVMs and aortopulmonary collaterals. Our discussion will include imaging with pacemakers. We will compare and contrast selection and optimization of conventional MRI sequences with metal artifact reduction sequences.
    Is Contrast Necessary for Pediatric & Congenital Heart Disease CMR?
15:55   Non-Contrast-Enhanced CMR Is Sufficient! Anastasia Fotaki

Keywords: Cardiovascular: Cardiovascular

Cardiac Magnetic Resonance Imaging plays a fundamental role in the care of patients with congenital heart disease. Current clinical protocols might necessitate the administration of contrast agents, particularly for anatomical imaging and tissue characterisation. This talk discusses emerging approaches for contrast-agent free CMR protocols, with the hope to motivate further application of these techniques for efficient, contrast-agent free imaging in CHD. 
16:20   Contrast-Enhanced CMR Is Necessary! Kim-Lien Nguyen
