Cardiac magnetic resonance allows for the characterization of the myocardium, providing an opportunity to re-evaluate traditional ECG and echocardiographic criteria for the early diagnosis of cardiac amyloidosis.
The noninvasive diagnosis of cardiac amyloidosis (CA) is often challenging. ECG abnormalities are common but lack both sensitivity and specificity. While some features on transthoracic echocardiography have confirmed the classical picture of CA, they have generally been validated against endomyocardial biopsy and thus are indicative of advanced disease. The ability of cardiac magnetic resonance to characterize the myocardium has opened a new door in the noninvasive diagnosis of CA, representing an opportunity to revisit the role of traditional ECG and transthoracic echocardiography diagnostic crtieria in earlier disease stages.

Pozo et al. (2014) conducted a review in Cardiac amyloidosis. Cardiac magnetic resonance vs. Traditional ECG and transthoracic echocardiography was evaluated. Cardiac magnetic resonance provides an opportunity to re-evaluate traditional ECG and echocardiography diagnostic criteria for cardiac amyloidosis in earlier disease stages.
