Figure 1
Three-dimensional reconstructed cardiac magnetic resonance imaging showing an area of scar (yellow) in the area of the sinus of Valsalva and an anomalous left circumflex artery arising from the right coronary artery (green star).
Figure 2
Figure 2
Catheter positions shown in the 3D mapping system (left) and in fluoroscopic anterior-posterior views (middle) inside the left coronary cusp (A) and below the left coronary cusp (B), with 1 surface electrocardiogram and intracardiac electrograms from the ablation catheter (right). Fractionated potentials were noted inside the left coronary cusp (A, right), but not below the cusp. Arrows indicate the amplitude (0.5 mV) and sweep speed (100 ms) of the intracardiac tracings.
Figure 3
Figure 3
A: Pacemap from the left coronary cusp (left), pacemap from the great cardiac vein (middle), and induction of ventricular tachycardia with isoproterenol (right). B: Bipolar and unipolar electrograms in the left coronary cusp during ventricular tachycardia at the successful ablation site. C: Termination of the tachycardia after 15 seconds of radiofrequency ablation. GCV = great cardiac vein; LCC = left coronary cusp.
