Left atrial physiology and pathophysiology: Role of deformation imaging

Figure 2 Cardiovascular magnetic resonance myocardial feature tracking of the left atrium in a patient with hypertrophic cardiomyopathy. Cardiovascular magnetic resonance myocardial feature tracking is performed in 4-chamber (A) and 2-chamber (B) views. Contours are based on 48 features, which are tracked throughout the cardiac cycle to generate longitudinal strain and strain rate profiles as displayed in Figure 1.
