Paradoxical preexcitation following successful ablation of a concealed accessory pathway
Catheter ablation is an established curative treatment for accessory pathways (APs), but in spite of the great progress made in the diagnosis and treatment, there is limited knowledge of the underlying cellular pathophysiology that determines the different clinical presentations. The case presented highlights the complex presentation and properties of some APs that can be encountered at the tim...
متن کاملCatheter ablation of a concealed accessory pathway between the right atrial appendage and the right ventricle.
Catheter ablation has become the treatment of choice for symptomatic patients with accessory pathways (acP) that connect the atria and the ventricles. For the most part, these connected both cardiac chambers at the level of the atrial-ventricular rings, although occasionally they are located at a certain distance from these, in unexpected places and generally unexplored. We present the case of ...
متن کاملAdenosine-5'-triphosphate test for the noninvasive diagnosis of concealed accessory pathway.
OBJECTIVES This study assessed the use of adenosine triphosphate (ATP) in the noninvasive diagnosis of concealed accessory pathway (AP) and dual atrioventricular (AV) node physiology in patients with inducible AV reentrant tachycardia (AVRT). BACKGROUND Administration of ATP during sinus rhythm identifies dual AV node physiology in 76% of patients with inducible sustained slow/fast AV nodal r...
متن کاملSupernormal conduction in the accessory pathway of patients with overt or concealed ventricular pre-excitation.
It was recently shown that supernormal conduction in the diseased His-Purkinje system is more common than previously thought, and is always associated with prolongation of refractoriness. To assess whether supernormal conduction could also occur in the accessory pathway of patients with ventricular pre-excitation, 21 patients with manifestly prolonged refractoriness in the accessory pathway wer...
متن کاملRadiofrequency ablation therapy in concealed left free wall accessory pathway with decremental conduction.
An electrophysiologic study followed by transcatheter radiofrequency ablation therapy was performed in two adult patients with a permanent form of junctional tachycardia. Both patients had no structural heart disease and exhibited a normal resting ECG. The P wave during tachycardia was negative in leads 1, 3, and aVF, biphasic over V6, and positive in V1 and aVL in both patients, while the P-R/...
