New Discovery of Left Atrial Macroreentry Tachycardia: Originating from the Spontaneous Scarring of Left Atrial Anterior Wall

Figure 3

Fusion of the voltage map and the enhanced cardiac CT. Low-voltage area on the LAAW at the left atrium (LA)-aorta (Ao) (a–d) or LA-pulmonary artery (PA) (e–h) or both (i–l) contiguity. The three-dimensional (3D) electroanatomic voltage maps in anteroposterior views (a, e, i) and merged (b, f, j) with 3D enhanced cardiac computed tomography (CT) (c, g, k) corresponding images of enhanced cardiac CT (d, h, l). Ao:  aorta; LA: left atrium; PA: pulmonary artery; LAA: left atrial appendage; MV: mitral valve; LSPV: left superior pulmonary vein; RSPV: right superior pulmonary vein.
