Like children, adult patients with active or abandoned epicardial pacing leads are also at risk of developing life-threatening cardiac ischemia due to mechanical compression of the coronary arteries. As this complication is amenable to surgical removal, these patients require periodic evaluation for myocardial ischemia even if they are asymptomatic.

Background: Conduction disturbances are a frequent occurrence after tricuspid valve surgeries, and their management is challenging.
Case Presentation: We present a case of 16-year-old male patient who presented with episodes of presyncope. At the age of 7 years, he underwent tricuspid valve replacement surgery with a biological prosthesis for infective endocarditis sourced from a gluteal abscess.

Background: Electrocardiographic imaging (ECGi) is a non-invasive technique for ventricular tachycardia (VT) ablation planning. However, it is limited to reconstructing epicardial surface activation. In-silico pace mapping combines a personalized computational model with clinical electrocardiograms (ECGs) to generate a virtual 3D pace map.

Background: Previous studies suggest the relationship between activation time (AT) and action potential duration (APD) in the heart is dependent on electrotonic coupling, but this has not been directly tested. This study assessed whether acute changes in electrical coupling, or other determinants of conduction or repolarization, modulate APD heterogeneity.
Methods And Results: Langendorff-perfused guinea pig hearts were epicardially paced and optically mapped after treatment with the gap junction uncoupler carbenoxolone, ephaptic uncoupler mannitol, ephaptic enhancer dextran 2MDa, sodium channel inhibitor flecainide, or rapid component of the delayed rectifier potassium channel inhibitor E4031.

Article Synopsis
- Cardiac strangulation is a rare issue in children that can occur years after epicardial pacemaker implantation due to the pacemaker wires compressing the heart and its blood vessels.
- A case was reported where a patient experienced this condition 8 years post-implantation, with imaging revealing significant compression of the left anterior descending artery.
- The patient underwent successful pacemaker reimplantation after myocardial perfusion imaging confirmed ischemia caused by this compression, highlighting the effectiveness of MPI in asymptomatic cases.
