Bottom Line: In the last decade, there has been increasing evidence that comprehensive evaluation of the left atrium is of utmost importance.Numerous studies have clearly demonstrated the prognostic value of left atrial volume for long-term outcome.Furthermore, advances in catheter ablation procedures used for the treatment of drug-refractory atrial fibrillation require the need for detailed knowledge of left atrial and pulmonary venous morphology as well of atrial wall characteristics.

ABSTRACT
In the last decade, there has been increasing evidence that comprehensive evaluation of the left atrium is of utmost importance. Numerous studies have clearly demonstrated the prognostic value of left atrial volume for long-term outcome. Furthermore, advances in catheter ablation procedures used for the treatment of drug-refractory atrial fibrillation require the need for detailed knowledge of left atrial and pulmonary venous morphology as well of atrial wall characteristics. This review article discusses the role of cardiac magnetic resonance and computed tomography in assessment of left atrial size, its normal and abnormal morphology, and function. Special interest is paid to the utility of these rapidly involving noninvasive imaging methods before and after atrial fibrillation ablation.

Mentions: Myxomas are the most common primary cardiac tumours, predominantly localized in the LA. Typically, myxomas are solitary, pedunculated lesions attached to the interatrial septum (Figure 9). In unenhanced scans, myxomas have lower attenuation compared with surrounding blood, and their attenuation is usually heterogeneous. On contrast-enhanced scans, this tumour is usually a heterogeneously enhancing structure, with varying degrees of attenuation corresponding to areas of hemorrhage, necrosis, cyst formation, and calcification [77].
