Anaplastic Large Cell Lymphoma Growing in the Pacemaker Pocket.

An 88-year-old patient underwent pacemaker generator replacement. Shortly after the replacement, the pacemaker pocket became swollen and, assuming a hematoma, underwent percutaneous drainage. However, the swelling was due to an aggressive lymphoma located in the pocket. This is the first described case of T-cell lymphoma in a pacemaker pocket.

Optimizing remote heart failure management: First experiences with the HeartInsight score for implanted defibrillators.

We explored the results of two tests of the novel HeartInsight algorithm for heart failure (HF) prediction, reconstructing trends from historical cases. Results suggest potential extension of HeartInsight to implantable cardioverter defibrillators patients without history of HF and illustrate the importance of the baseline clinical profile in enhancing algorithm specificity.
