We assessed the correlation between TTE and CMR in the quantification of MR. Participants with isolated MR and echocardiographic mitral regurgitant volume (RVol) \u2265 30 mL\/beat were included. A consecutive sample of 30 participants (Mean age 52.7 \u00b1 19.3 years, 50% males) was selected and referred for indirect and direct CMR quantification of mitral RVol. There was a statistically significant strong positive correlation between the echocardiographic and indirect CMR quantification of the mitral RVol (r = 0.753, P &lt; 0.001) and a statistically significant moderate positive correlation between the echocardiographic and direct CMR quantification of the mitral RVol (r = 0.530, P &lt; 0.003). The inter-observer reliability of the MR grade between TTE and CMR showed a statistically significant moderate agreement (\u03ba = 0.502, P = 0.0001) when the observers used the echocardiographic mitral RVol for grading of MR. On the other hand, the inter-observer reliability of the MR grade between TTE and CMR showed a statistically significant faint agreement (\u03ba = 0.251, P = 0.024) when the observers used the echocardiographic regurgitant fraction (RF) for grading of MR. The positive reciprocal relationship between the CMR and the TTE highlights the potential role of the CMR as a concomitant imaging tool for quantification of the mitral RVol and grading of isolated MR, especially with limited or inconclusive TTE studies. This will enhance the management strategy and improve outcomes.<\/jats:p>","DOI":"10.31083\/j.rcm.2021.01.20216","type":"journal-article","created":{"date-parts":[[2021,4,2]],"date-time":"2021-04-02T00:44:00Z","timestamp":1617324240000},"source":"Crossref","is-referenced-by-count":1,"title":["Quantification of mitral regurgitation using transthoracic echocardiography and cardiac magnetic resonance imaging"],"prefix":"10.31083","volume":"22","author":[{"given":"Walid MS.","family":"ElTahlawy","sequence":"first","affiliation":[{"name":"Heart and Vascular Institute, Cardiology department, Cleveland Clinic Abu Dhabi, 112412 Abu Dhabi, United Arab of Emirates"},{"name":"Cardiology Department, Faculty of Medicice, AlFayoum University, 63514 AlFayoum, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamer M.","family":"Ragab","sequence":"first","affiliation":[{"name":"Cardiology Department, Faculty of Medicice, AlFayoum University, 63514 AlFayoum, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khaled A.","family":"Elkhashab","sequence":"first","affiliation":[{"name":"Cardiology Department, Faculty of Medicice, AlFayoum University, 63514 AlFayoum, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hassan M.","family":"Ebeid","sequence":"first","affiliation":[{"name":"Cardiology Department, Faculty of Medicice, AlFayoum University, 63514 AlFayoum, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2021,3,30]]},"reference":[{"key":"ref1","unstructured":"Mozaffarian D, Benjamin EJ, Go AS, Amett DK, Blaha MJ, Cushman M, et al.
