Figure Lengend Snippet: Left Atrial Anatomical Maps Illustrating Delivered Ablation Lesions Three-dimensional left atrial electroanatomic maps in (A) anteroposterior, (B) posteroanterior, (C) left anterior oblique, (D) right anterior oblique, and (E and F) lateral projections were generated using the CARTO system. Lesions within the maps are displayed as red spheres, which indicate sites of ablation.

Article Snippet: After transseptal puncture guided by fluoroscopy and intracardiac echocardiography, a 3-dimensional left atrial electroanatomic map (CARTO, Biosense Webster) was generated ( ).

Article Title: Ablation of Atrial Flutter in a Patient With Mustard Procedure Using Integration of Real-Time Electroanatomical Mapping With 3-Dimensional Computed Tomographic Imaging

Figure Lengend Snippet: Figure 2. An anterior (A) and a posterior (B) view of the 3-dimensional electroanatomical map of the heart and the great arteries, created with real-time integration with high-resolution contrast-enhanced cardiac computed tomography images. C, Cut-away anterior coronal view of the same electroanatomical map reveals a highly accurate anatomic construct of the venous baffle as well as the venae cavae and the interior of the PVA and the SVV. D, Right anterior oblique fluoroscopic view of the heart with all the catheters in position. AO indicates aorta; IVC, inferior vena cava; PA, pulmonary artery; PVA, pulmonary venous atrium; PVV, pulmonary venous (right) ventricle; SVC, superior vena cava; SVV, systemic venous (left) ventricle; VB, venous baffle; R1, recording catheter 1 (placed inside the baffle); R2, recording catheter 2 (placed in the apex of the SVV via the baffle); Apex, apex of SVV; MAP, mapping catheter (advanced to the floor of the PVA via the aorta and the PVV in a retrograde fashion); and TA, tricuspid annulus.

Figure Lengend Snippet: Figure 3. A, External view of the integrated 3-dimensional car- diac electroanatomical map. B, Cut-away sagital internal view of the integrated 3-dimensional cardiac electroanatomical map. The white circles (arrow) denote sites where entrainment of the tachycardia resulted in exact postpacing return cycles. The red circles (arrow) represent sites of radiofrequency application. The middle panel shows atrial intracardiac ECGs of atrial flutter entrainment from the TA isthmus/floor of the PVA, with 3 paced beats followed by resumption of atrial flutter. Pacing at a cycle length of 275 ms (a) resulted in a postpacing interval of 295 ms (b), identical to the tachycardia cycle length (c), which demon- strated participation of these areas in the atrial flutter circuit. The lower panel illustrates atrial ECGs that demonstrated termi- nation of atrial flutter during radiofrequency delivery (arrow) with restoration of sinus rhythm. For successful elimination of the atrial flutter, RF was delivered to the TA isthmus from inside the PVA along a region that stretched from the lateral wall to the TA, and also to the floor of the venous baffle.
