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.

fig8: Contrast-enhanced CT scan showing two left-sided and two right-sided pulmonary veins.

Mentions: Approximately 70% of the general population has the classical configuration of four pulmonary veins: left superior and inferior pulmonary veins and right superior and inferior pulmonary veins, with four independent ostia (Figure 8) [83]. Pulmonary venous variations or abnormalities are related to the complex development of the venous system during first weeks of gestation. The most frequent abnormalities are left-sided pulmonary veins with a common ostium and a third right-sided pulmonary vein [84]. Pulmonary vein ostia have variable diameters, usually ranging between 9 and 13 mm in patients without AF [85] and between 12 and 24 mm in individuals with AF undergoing AF ablation procedure [86].
