Multimodality Imaging in Patients with Hypertrophic Cardiomyopathy and Atrial Fibrillation

Figures

• 

  Figure 1. Speckle-tracking analysis and strain measurements of phasic LA strain. LAScd, left atrial conduit strain; LASct, left atrial contractile strain; and LASr, left atrial reservoir strain.

• 

  Figure 2. A representative left ventricular strain image by two-dimensional speckle-tracking echocardiography in an HCM patient with asymmetrical septal hypertrophy. Two-dimensional echocardiographic image of asymmetrical septal hypertrophy (A). Global and regional longitudinal deformation assessed by speckle-tracking analysis from apical 4 chamber (B), 3 chamber (C) and 2 chamber (D) views. The global longitudinal strain (GLS) is –8.6% (E). HCM, hypertrophic cardiomyopathy.

• 

  Figure 3. A representative left atrial strain image by CMR-FT in HCM patients. Left atrial strain (A) and volume (B). The ejection fraction is 45%, and the global longitudinal strain is 27.8% (C). CMR, cardiac magnetic resonance; FT, feature tracking.

• 

  Figure 4. A representative left ventricular strain imaging by CMR-FT in an HCM patient. LV endocardial and epicardial contours are manually delineated at the end-diastole phase in 2 chamber (A), 4 chamber (B), LV outflow tract (C), and sort axis (D) cine images. The global longitudinal strain is −17.51% (E). CMR, cardiac magnetic resonance; FT, feature tracking; LV, left ventricle.
