“…This finding is consistent with other publications, where low weight was not a determinant of failure 14 . Another finding, also according to the literature 4,[12][13][14] , was the lower success rate in the population with congenital heart disease, when compared to patients without structural heart disease, due to anatomical variations found in this population.…”

Background: This study aimed to investigate the impact of aging on electrophysiological characteristics in patients with atrioventricular nodal re-entrant tachycardia (AVNRT). Methods and Results:The 2,111 patients who underwent an electrophysiological study and radiofrequency (RF) catheter ablation of AVNRT were enrolled. The patients were divided into 4 groups according to age (group 1: <20 years; group 2: 20-39 years; group 3: 40-59 years; and group 4: ≥60 years). The gender distribution differed with age. The atrio-Hisian interval, and effective refractory periods (ERP) of the right atrium, ventricle, antegrade slow pathway, retrograde slow pathway and fast pathway, and tachycardia cycle length all increased with age. However, a paradoxical change in the fast pathway ERP was noted. The fast pathway ERP was significantly longer in group 2 than in other groups, and was associated with the largest tachycardia window. The response to catecholamines was similar between different age groups. Procedure time, radiation time, and complications did not differ. However, the number of RF impulses was higher in group 2 compared with other groups (7.6±9.3, P=0.04), which might imply a differing complexity during the ablation. Conclusions:Paradoxical aging changes of AVN electrophysiological characteristics were associated with a different atrioventricular nodal conduction property and the number of RF impulses.

“…Clues to the diagnosis can be subtle at all stages of the disease. TMC can occur at any age, including in utero [29] or in toddlers [30]. Physical fi ndings are nonspecifi c. Patients with early TMC and no underlying heart disease or gradual development of cardiomyopathy may have no symptoms.…”

Tachycardia-mediated cardiomyopathy is a cause of ventricular dysfunction due to, at least partially, persistent tachycardia leading to cellular and extracellular perturbations. Cardiomyopathy may take years to develop, but pharmacologic management to achieve rate control and reverse remodeling, as well as cardioversion or ablative strategies to stop the tachycardia, can result in rapid recovery from symptoms and gradual improvement in left ventricular ejection fraction. However, ultrastructural changes can remain and may lead to a rapid decline in ventricular function if tachycardia recurs. Ultrastructural changes may also explain a propensity toward sudden death even if the ejection fraction normalizes. Although the etiology, pathophysiology, and late clinical manifestations of tachycardia-mediated cardiomyopathy are beginning to be understood, investigation continues, focusing on prevention, early recognition, and acute and long-term management in an attempt to lessen heart failure and prevent risk of sudden death.
