Cardiac magnetic resonance (CMR) has emerged as a useful non‐invasive tool for the assessment of cardiovascular morphology and function in the absence of ionizing radiation. It has imaging sequences that can be manipulated to generate varying degrees of soft‐tissue contrast for cardiac tissue characterization. Additionally, the excellent spatial (1–2 mm in‐plane resolution), temporal (50ms or better), and contrast resolutions allow for routine assessment of cardiac function and blood flow [52, 53]. The main limitations of CMR are the inability to image very large or claustrophobic patients, long scan time, contraindications such as certain implanted devices/clips and the risk of nephrogenic systemic fibrosis from gadolinium contrast in patients with impaired renal function. However, the ability of CMR to provide comprehensive evaluations of cardiovascular morphology, function, and pathology makes it an attractive tool for the assessment and planning of patients undergoing cardiac interventional procedures.
