| description | Background
Right ventricle (RV) evaluation requires dedicated imaging to achieve a comprehensive functional and anatomical assessment. Right ventricular imaging could be technically difficult which results in suboptimal visibility and inconsistent assessment between observers. The aim of this study was to assess feasibility and the additive value of contrast enhancement for right ventricular evaluation.
Methods
Eighty patients referred for clinically indicated echocardiography studies were included. Patients with irregular rhythms were excluded. Dedicated RV‐focused view was attained; RV dimensions measured, and RV segment visualization and wall motion were assessed with and without contrast enhancement. Paired sample t test was used to compare continuous variables, Wilcoxon signed‐rank test to compare segments visualization on enhanced versus (vs) nonenhanced images, and Cohen kappa coefficient to assess the agreement of wall motion between two observers. Reproducibility was measured by the absolute mean difference method.
Results
A total of 240 total segments of 80 patients were analyzed, and 178 (74%) were visible on unenhanced while 221 (92%) on enhanced images, P |

Results
A total of 240 total segments of 80 patients were analyzed, and 178 (74%) were visible on unenhanced while 221 (92%) on enhanced images, P < .05. Further, RV measurements on enhanced images were consistently larger on RV focused, SAX, and RVOT. Inter‐ and intra‐observer reproducibility showed a higher reproducibility with a lower bias on enhanced images. Absolute agreement on RV segmental wall motion between two independent observers was higher on enhanced images. Percent agreement was 78% on UE vs 89% on CE.
Conclusion
Contrast RV imaging is feasible and improves RV segment visualization and inter‐observer agreement. Compared with unenhanced images, RV measurements on contrast images are larger and more reproducible with lower bias.</description><identifier>ISSN: 0742-2822</identifier><identifier>EISSN: 1540-8175</identifier><identifier>DOI: 10.1111/echo.14504</identifier><identifier>PMID: 31633241</identifier><language>eng</language><publisher>United States</publisher><subject>contrast echocardiography ; contrast imaging ; right ventricle ; right ventricular function</subject><ispartof>Echocardiography (Mount Kisco, N.Y.), 2019-11, Vol.36 (11), p.1979-1988</ispartof><rights>2019 Wiley Periodicals, Inc.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3294-23a0080022e186756e8482d867af492a3d6f57583c99cfe603cfb751889c66cf3</citedby><cites>FETCH-LOGICAL-c3294-23a0080022e186756e8482d867af492a3d6f57583c99cfe603cfb751889c66cf3</cites><orcidid>0000-0003-3842-096X ; 0000-0002-5604-3670</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fecho.14504$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fecho.14504$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,776,780,1411,27901,27902,45550,45551</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31633241$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Pereira, Jason B.</creatorcontrib><creatorcontrib>Essa, Mohammed</creatorcontrib><creatorcontrib>Ugonabo, Ifeoma</creatorcontrib><creatorcontrib>Hur, David J.</creatorcontrib><creatorcontrib>Crandall, Ian</creatorcontrib><creatorcontrib>Vaccarelli, Michael</creatorcontrib><creatorcontrib>Sugeng, Lissa</creatorcontrib><title>The feasibility of contrast echocardiography in the assessment of right ventricular size and function</title><title>Echocardiography (Mount Kisco, N.Y.)</title><addtitle>Echocardiography</addtitle><description>Background
