Left atrial posterior wall (LAPW) residual potentials via epicardial connections during LAPW isolation are often low-frequency continuous potentials. Accurate annotation of these residual potentials by three-dimensional electroanatomical mapping systems is challenging and can be misleading. Herein, we present a case of successful LAPW isolation using peak frequency analysis.

Potential effects of liver dysfunction at the time of diagnosis in patients with acute myeloid leukemia.
Exp Ther Med
February 2025
Department of Hematology, Etlik City Hospital, Ankara 06170, Turkey.
Whilst severe liver dysfunction is rarely encountered at the time of diagnosis for patients with acute myeloid leukemia (AML), mild elevations aminotransferase (<5 times the upper limit of normal) may be more frequently seen. Liver dysfunction at the time of diagnosis of AML is a parameter that requires investigation and can assist the clinicians in predicting prognosis. The aim of the present study was to investigate liver dysfunction at the time of diagnosis using the assoicated parameters in patients with AML.

Background: A novel contact force (CF) sensing catheter with a mesh-shaped irrigation tip (TactiFlexTM SE, Abbott), is expected to provide safe and effective radiofrequency ablation. Our previous study revealed that the TactiFlex catheter needs a higher power for pulmonary vein isolation (PVI) due to the long tip length. This study aimed to examine the feasibility and safety of a 50 W ablation with the TactiFlex for PVI of atrial fibrillation (AF).

Introduction: Some targets of relational peer victimization become depressed because of their poor treatment. These associations are well documented in youth but are rarely studied in adults.
Methods: The longitudinal pathways between relational peer victimization (being excluded, stonewalled, etc.
