External validation of EuroSCORE I and II in patients with infective endocarditis: results from a nationwide prospective registry.

Objectives: The primary objective was to externally validate EuroSCORE I and II in surgically treated endocarditis patients. The secondary objective was to assess the predictive performance of both models across sex, redo surgery, age, and urgency.

Methods: Data were retrieved from the Netherlands Heart Registration.

Worsening tricuspid regurgitation after ICD implantation is rather due to transvenous lead than natural progression.

Background: Transvenous implantable cardioverter-defibrillators (TV-ICDs) are associated with greater tricuspid regurgitation (TR) severity, which leads to increased mortality. The pathophysiology is assumed to be lead-related, hence, treatment includes lead extraction. However, TR may also naturally occur in the high-risk ICD population, or may be caused by right ventricular pacing.
