The restoration of right ventricle dysfunction is essential to the maintenance of systemic circulation in patients after cardiac surgery.It also plays a significant part in planning surgical repair following the last stage of surgical palliation.Nevertheless,the complex geometry and wall motion of the right ventricle make it difficult to evaluate the right ventricle function with the noninvasive tools.Cardiac magnetic resonance(CMR)is the gold standard of the most commonly used technology for cardiac imaging,which is necessary to be involved in regular surveillance for patients undergoing complicated cardiac surgery.The application of new CMR technology mainly includes 4D flow hemodynamic measurement,MR1 mapping and tracking technology to evaluate the right ventricular function by detecting the myocardial injury.Echocardiography is the first-line method of postoperative assessment and appropriate for all kinds of congenital heart disease.Speckle-tracking echocardiography has been further development in recent years.Cardiac computed tomography has prominent advantages in detecting the vessels and pulmonary lesions,which is often used as an alternative to MRI.The development of artificial intelligence in image processing technology has greatly improved the diagnostic and predictive value of imaging examination.By comparing the characteristics of CMR,echocardiography and cardiac computed tomography,this paper reviews the research progress of these three imaging methods in the evaluation of the postoperative right ventricle function in congenital heart disease.
