The researchers are doing this study to see how well cardiac magnetic resonance imaging (CMR) scans can be used to examine the properties of central venous catheter-associated right atrial clot (RA clot). This could help doctors decide on the best treatment options.
Documentation of Disease
Definition of Disease [or Measurable Disease]
Cardiac mass (CMASS) will be initially localized on cine-CMR, on which it is defined via established criteria as a discrete tissue prominence independent from normal anatomic structures, quantified based on size (area, cross-sectional linear dimensions)
CMASS will be further categorized by type (CNEO or CTHR) based on CMR tissue characterization: CNEO and CTHR can be differentiated based on presence of contrast enhancement via the reference standard of LGE-CMR using established criteria previously validated by our group and others.
Known pre-existing CV disease which can affect hemodynamics within cardiac chambers as determined by the investigator, including
Arrhythmia - chronic persistent atrial arrhythmias
Cardiomyopathies including Ischemic or non-ischemic cardiomyopathy with LVEF <53%
Restrictive cardiomyopathy - cardiac amyloidosis, myocardial fibrosis
