All pts were in sinus rhythm, without congestive heart failure and without coronary artery disease at selective coronary angiography; 30\u00b0 right anterior oblique ventricculograms were employed in each case. Thirty\u2010six radiants were automatically traced and the percent shortening of each radiant was calculated using two different reference methods (fix and floating methods).<\/jats:p><jats:p>In valvular heart disease (VHD) pts LV volumes were significantly increased, and ejection fraction and LV eccentricity were significantly reduced. LV eccentricity inversely correlated with LV volumes.<\/jats:p><jats:p>VHD pts showed regional LV abnormalities. Inferoapical and anterior wall motion was significantly reduced (two\u2010sample t\u2010test P &lt; 0.05) using the fix method. With this method a significant inverse correlation between percent shortening of the radiants correspondent to the inferoapical region and end\u2010diastolic and end\u2010systolic volumes was found; a significant direct correlation was found with LV systolic eccentricity. Ejection fraction directly correlated with the percent shortening of radiants correspondent to both the anterior and inferior regions.<\/jats:p><jats:p>The role of LV \u201cdynamic geometry\u201d alterations as a possible cause for the observed regional LV wall motion abnormalities is emphasized.<\/jats:p>","DOI":"10.1002\/ccd.1810090504","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T10:43:30Z","timestamp":1172745810000},"page":"453-462","source":"Crossref","is-referenced-by-count":8,"title":["Regional left ventricular wall motion abnormalities in chronic volume overload"],"prefix":"10.1002","volume":"9","author":[{"given":"Marisa Di","family":"Donato","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe","family":"Barletta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio","family":"Mori","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio","family":"Fantini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,24]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(81)90186-7"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.54.6.975"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(81)90383-0"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.31.4.474"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.47.6.1252"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0033-0620(73)80007-6"},{"key":"e_1_2_1_8_2","first-page":"109","article-title":"Patterns of contraction in the human left ventricle.","volume":"40","author":"Hood WP","year":"1969","journal-title":"Circulation"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(77)80187-2"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.61.1.148"},{"key":"e_1_2_1_11_2","volume-title":"From Cardiac Catheterization Data to Hemodynamic Parameters","author":"Yang SS","year":"1978"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.48.4.786"},{"key":"e_1_2_1_13_2","first-page":"71","article-title":"Relationship between left ventricular shape, size and function in heart disease.","volume":"18","author":"Rackley CE","year":"1970","journal-title":"Clin Res"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.45.5.943"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.65.7.1518"},{"key":"e_1_2_1_16_2","first-page":"173","article-title":"Fiber orientation in normal and hypertensive cadaver left ventricle.","volume":"45","author":"Jean CF","year":"1972","journal-title":"Circulation"},{"key":"e_1_2_1_17_2","first-page":"325","article-title":"Contractile responses of the left ventricle to acute and chronic stress.","volume":"1","author":"Ross J","year":"1974","journal-title":"Eur J Cardiol"},{"key":"e_1_2_1_18_2","first-page":"229","article-title":"Nonuniform subendocardial fiber orientation in the normal macaque left ventricle.","volume":"3","author":"Ross MA","year":"1975","journal-title":"Eur J Cardiol"}],"container-title":["Catheterization and Cardiovascular Diagnosis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.1810090504","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.1810090504","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,19]],"date-time":"2023-10-19T22:58:58Z","timestamp":1697756338000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.1810090504"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1983,1]]},"references-count":17,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1983,1]]}},"alternative-id":["10.1002\/ccd.1810090504"],"URL":"https:\/\/doi.org\/10.1002\/ccd.1810090504","archive":["Portico"],"relation":{},"ISSN":["0098-6569","1097-0304"],"issn-type":[{"value":"0098-6569","type":"print"},{"value":"1097-0304","type":"electronic"}],"subject":[],"published":{"date-parts":[[1983,1]]}}}
