From Signals to Colours

Potentials.- Counter-clockwise Isthmus-Dependent Peritricuspid Reentry with an Atypical Electrocardiographic Pattern: what Should Be Complex is not Always Actually Complex.- Recurrence of Typical Counter-clockwise Atrial Flutter in a Postsurgical Patient: an Unexpected Trap.- Two Macroreentrant Tachycardias in a Patient after Fontan Surgery: the Difference between "Isthmic" and "Rotational" Atrial Macroreentry.- Organised Atrial Arrhythmias after Atrial Fibrillation Ablation in the Left Atrium (Example 1): an Arrhythmogenic Incomplete Linear Lesion with Modified Left-to-right Atrial Propagation.- Organised Atrial Arrhythmias after Atrial Fibrillation Ablation in the Left Atrium (Example 2): Association of Multiple Potentially Pro-arrhythmogenic Factors Resulting in a Tachycardia with a Longer Cycle Length.- Organised Atrial Arrhythmias after Atrial Fibrillation Ablation in the Left Atrium (Example 3): do Lesions in the Left Atrium Have a Mid-term Evolution?.- A Non-clinical Macroreentrant Right Atrial Tachycardia with Two Independent Loops: the Exception to the Rule of a Shared Mid-diastolic Isthmus in Double-loop Reentry.- A Peculiar Clockwise Peritricuspid Atrial Flutter: the Exception to the Rule of Aiming at the Mid-diastolic Isthmus.- Atrial Ablation Based on Substrate Mapping in Sinus Rhythm.- Non-inducible Atrial Flutter in a Patient with Prior Surgery for Congenital Heart Disease (Example 1): Ablation Based on Substrate Mapping in Sinus Rhythm.- Non-inducible Atrial Flutter in a Patient with Prior Surgery for Congenital Heart Disease (Example 2): Substrate Mapping in Sinus Rhythm with the Help of Imaging Integration.- Peculiar Anatomies.- Isolated Congenital Unilateral Absence of the Right Pulmonary Artery and Left Atrial Flutter: Are they Related?.- Left Atrial Ablation of Atrial Fibrillation in a Patient with Dextrocardia: the Complexities of an Inverted Anatomy.- Uncommon Anatomy of the Pulmonary Veins (Example 1): Common Trunk of the Inferior Pulmonary Veins.- Uncommon Anatomy of the Pulmonary Veins (Example 2): the "Roof Pulmonary Vein".
