Introduction: Differences in predictability of ablation success for premature ventricular contractions (PVCs) between earliest isochronal map area (EIA), local activation time (LAT) differences on unipolar and bipolar electrograms (⊿LAT), LAT prematurity on bipolar electrograms (LAT), and unipolar morphology of QS or Q pattern remain unclear. We verified multiple statistical predictabilities of those indicators of ablation success on mapped cardiac surface.

Methods: Thirty-five patients with multiple PVCs underwent catheter ablation after LAT mapping using multipolar mapping catheters with unipolar-based annotation.

Article Synopsis
  • Venous thromboembolism (VTE), often called cancer-associated thrombosis (CAT), is a common issue among cancer patients, yet its clinical features are not well-studied.
  • A study analyzed 259 patients treated for pulmonary embolism (PE), finding that those with cancer were more often diagnosed incidentally and had lower severity of PE but experienced a worse prognosis.
  • Higher D-dimer levels at discharge were linked to poor outcomes, indicating that cancer patients might face a heightened risk of major cardiovascular events and mortality despite the less severe initial PE.

Background: Nearly one-third of patients with advanced heart failure (HF) do not benefit from cardiac resynchronization therapy (CRT). We developed a novel approach for optimizing CRT via a simultaneous assessment of the myocardial viability and an appropriate lead position using a fusion technique with CT coronary venography and myocardial perfusion imaging.

Methods And Results: The myocardial viability and coronary venous anatomy were evaluated by resting Tc-99m-tetrofosmin myocardial perfusion imaging (MPI) and contrast CT venography, respectively.
