ECG-gated MDCT after aortic and mitral valve surgery

AJR Am J Roentgenol. 2014 Dec;203(6):W596-604. doi: 10.2214/AJR.13.12404.

Abstract

Objective: The purpose of this article is to review the utility of ECG-gated MDCT in evaluating postsurgical findings in aortic and mitral valves. Normal and pathologic findings after aortic and mitral valve corrective surgery are shown in correlation with the findings of the traditionally used imaging modalities echocardiography and fluoroscopy to assist in accurate noninvasive anatomic and dynamic evaluation of postsurgical valvular abnormalities.

Conclusion: Because of its superior spatial and adequate temporal resolution, ECG-gated MDCT has emerged as a robust diagnostic tool in the evaluation and treatment of patients with postsurgical valvular abnormalities.

Keywords: ECG-gated MDCT; cardiac valves; echocardiography; fluoroscopy; paravalvular regurgitation; postsurgical valve abnormalities; prosthetic valves.
