The causality between carotid and cardiac pathologies is unknown. We aim to explore the effects of carotid stenosis or occlusion on cardiac pathology and function.<\/jats:p><jats:p><jats:bold>Methods and Results:<\/jats:bold> We produced carotid obstruction or stenosis in 36 atherogenic mice with 150- or 300-\u03bcm tandem surgery or sham surgery. The structure and function of the heart were assessed by histology and animal ultrasound. The 150-\u03bcm group had larger plaque burden and thicker valve leaflets in the aortic root than did the control group. Also, the two surgery groups had a thicker left ventricular posterior wall and smaller internal diameter compared with controls. Increased myocardial fibrosis was also found in the 150-\u03bcm group compared with controls, although the surgery groups had preserved systolic function compared with that of controls.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> In a mouse model, carotid occlusion accentuated the formation of aortic stenosis and promoted ventricular remodeling without impairing systolic function. Carotid atherosclerotic plaque may be a pathogenic factor for aortic stenosis and ventricular remodeling.<\/jats:p>","DOI":"10.3389\/fphys.2020.578722","type":"journal-article","created":{"date-parts":[[2021,1,13]],"date-time":"2021-01-13T01:13:00Z","timestamp":1610500380000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Carotid Occlusion Accentuates Aortic Stenosis and Cardiac Remodeling With Preserved Systolic Function in LDL Receptor-Deficient Mice"],"prefix":"10.3389","volume":"11","author":[{"given":"Yandong","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiawei","family":"Cai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lefeng","family":"Qu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,1,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"823","DOI":"10.1111\/j.1540-8175.2008.00891.x","article-title":"Echo-tracking assessment of carotid artery stiffness in patients with aortic valve stenosis.","volume":"26","author":"Antonini-Canterin","year":"2009","journal-title":"Echocardiography"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1852","DOI":"10.1161\/CIRCRESAHA.114.302721","article-title":"Mechanisms of plaque formation and rupture.","volume":"114","author":"Bentzon","year":"2014","journal-title":"Circ.
