Article Synopsis
  • The study aimed to evaluate the safety and performance of two new types of left ventricular leads, NAVIGO 4LV 2D and NAVIGO 4LV ARC, in patients undergoing cardiac resynchronization therapy.
  • Results showed a high implantation success rate of 97.2% with minimal lead-related complications: 100% for NAVIGO 4LV 2D and 96.1% for ARC.
  • Both leads demonstrated excellent performance, with over 98% of patients achieving successful lead performance and a global complication-free rate of 97.1% after 12 months.

Article Synopsis
  • The study aimed to validate three multiparametric scores (Delise, Sieira, Shanghai BrS) for risk stratification in patients with Brugada syndrome (BrS) who underwent electrophysiological studies (EPS).
  • A total of 831 patients were studied over an average of 10.2 years, revealing that common risk factors like type 1 ECG and syncope were important predictors of arrhythmic events, with 5.7% experiencing such events during follow-up.
  • Although the multiparametric scores were linked to arrhythmic events, their predictive abilities were modest, particularly for asymptomatic patients, indicating the need for improved risk assessment methods.

Background Fat deposition (FD) is part of the healing process after myocardial infarction. The characteristics of FD and its impact on the outcome in patients undergoing ventricular tachycardia (VT) ablation have not been thoroughly studied. Methods and Results We studied consecutive patients undergoing post-myocardial infarction VT ablation with pre-procedural cardiac computed tomography.

Background: The significance of fractionated electrograms (EGMs) is object of debate, with multiple mechanisms described.

Objective: Using Rhythmia, a high-density mapping system, we sought to investigate the relationship between specific electrophysiological phenomena and EGM characteristics at those sites.

Methods: Twenty-five consecutive patients underwent high-density atrial mapping during atrial tachycardias.

We sought to determine whether preoperative statin treatment is more effective in reducing, after cardiac surgery with cardiopulmonary bypass, systemic inflammatory response and myocardial damage markers in patients who have elevated preoperative interleukin-6 levels than in patients who have normal preoperative interleukin-6 levels. The study involved a prospective cohort of 164 patients who underwent coronary and valvular surgery with cardiopulmonary bypass. There were 2 study groups: group A (n = 60), patients with elevated preoperative interleukin-6 levels; and group B (n = 104), patients with normal preoperative interleukin-6 levels.
