Three-dimensional echocardiography is being used with increasing frequency to evaluate cardiac function and structure. We present two cases of prosthetic aortic valve endocarditis where three-dimensional transesophageal echocardiography correlated with the intraoperative surgical findings of prosthetic dehiscence and communication with an abscess cavity. When compared with two-dimensional transesophageal echocardiography, three-dimensional echocardiography was more accurate in defining the exact site of dehiscence and communication with an abscess cavity. The echocardiographic images were oriented as a clockface watch to conform to the surgeon's visualization of the aortic root as viewed from the right side of the patient.
We present a patient with total right coronary artery occlusion produced by a prosthetic aortic valve abscess. The diagnosis was made by transesophageal three-dimensional echocardiography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
