Levels of agreement between cardiac magnetic resonance and conductance catheter measurements of right ventricular volumes after pulmonary artery banding

Levels of agreement between cardiac magnetic resonance and conductance catheter measurements of right ventricular volumes after pulmonary artery banding

Background Pressure-volume analysis is the gold standard for quantifying pump function of the right ventricle (RV); however, volume measurements based on a conductive catheter may be imprecise. The reference method for volume assessment is cardiac magnetic resonance (CMR). Purpose To determine the l...

description Background Pressure-volume analysis is the gold standard for quantifying pump function of the right ventricle (RV); however, volume measurements based on a conductive catheter may be imprecise. The reference method for volume assessment is cardiac magnetic resonance (CMR). Purpose To determine the levels of agreement between RV volume measurements obtained by cine CMR, phase-contrast CMR (PC CMR), and a conductance catheter in an animal model. Material and Methods CMR was performed in 20 sheep three months after pulmonary artery banding. Ejection fraction (EF), end-diastolic (EDV), end-systolic (ESV), and stroke volumes (SV) were obtained by cine CMR and conductance catheter. Results Statistically significant differences between cine CMR and conductance catheter derived volume measurements were found for EDV (P

Bland–Altman analysis showed very poor agreement between the two methods: EDV, bias 36.27 mL, agreement of limits 1.96–70.57 mL; ESV, bias 15.33 mL, agreement of limits –6.89–37.55 mL; and SV, bias 20.69 mL, agreement of limits 8.01–49.10 mL. Good agreement was found for SV between cine CMR and PC CMR (bias –7.0 mL, agreement of limits –24.01–9.98 mL), while SV derived from PC CMR measurements showed poor agreement with conductance catheter (bias 27.76 mL, agreement of limits –3.84–59.26 mL). Conclusion Poor agreement between the conductance catheter and CMR RV volume measurements was found. PC CMR and cine CMR measurements of SV agreed well.</description><identifier>ISSN: 0284-1851</identifier><identifier>EISSN: 1600-0455</identifier><identifier>DOI: 10.1177/0284185119886318</identifier><language>eng</language><publisher>London, England: SAGE Publications</publisher><ispartof>Acta radiologica (1987), 2020-07, Vol.61 (7), p.894-902</ispartof><rights>The Foundation Acta Radiologica 2019</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c314t-2c7a4e843d0e86b2bd20292a72abe57a39a9634eef2da1d7859691448bf285693</citedby><cites>FETCH-LOGICAL-c314t-2c7a4e843d0e86b2bd20292a72abe57a39a9634eef2da1d7859691448bf285693</cites><orcidid>0000-0002-5552-8385</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://journals.sagepub.com/doi/pdf/10.1177/0284185119886318$$EPDF$$P50$$Gsage$$H</linktopdf><linktohtml>$$Uhttps://journals.sagepub.com/doi/10.1177/0284185119886318$$EHTML$$P50$$Gsage$$H</linktohtml><link.rule.ids>314,780,784,21819,27924,27925,43621,43622</link.rule.ids></links><search><creatorcontrib>Gufler, Hubert</creatorcontrib><creatorcontrib>Wagner, Sabine</creatorcontrib><creatorcontrib>Niefeldt, Sabine</creatorcontrib><creatorcontrib>Klopsch, Christian</creatorcontrib><creatorcontrib>Brill, Richard</creatorcontrib><creatorcontrib>Wohlgemuth, Walter Alexander</creatorcontrib><creatorcontrib>Yerebakan, Can</creatorcontrib><title>Levels of agreement between cardiac magnetic resonance and conductance catheter measurements of right ventricular volumes after pulmonary artery banding</title><title>Acta radiologica (1987)</title><description>Background Pressure-volume analysis is the gold standard for quantifying pump function of the right ventricle (RV); however, volume measurements based on a conductive catheter may be imprecise.
