Background: The INGEVITY lead (Boston Scientific, St Paul, MN, USA) has excellent clinical performance. However, its single filar design results in decreased lead tensile strength and a possible challenging extraction. This study's goal is to evaluate techniques for extracting the INGEVITY lead.

- This study aimed to analyze sensor data from implantable devices in heart failure patients, comparing their values during stable periods to the times before and after heart failure events.
- Data from 900 patients were collected over a year, revealing that poorer sensor readings during stable periods were linked to subsequent heart failure events in some patients.
- The findings indicate that these sensors can help identify worsening conditions before acute heart failure occurs and show recovery after treatment.
Background: Care of heart failure (HF) patients results in a high burden on healthcare resources, and estimating prognosis is becoming increasingly important to triage resources wisely. Natriuretic peptides are recommended prognosticators in chronic HF. Our objective was to evaluate whether a multisensor HF index and alert algorithm (HeartLogic) replaces or augments current HF risk stratification.

- The study focused on complications from transvenous implantable cardioverter-defibrillator (ICD) leads, which are the most common issue in traditional ICD systems.
- Researchers analyzed data from over 40,000 patients with new ICDs or cardiac resynchronization therapy defibrillators, finding that 5.3% experienced mechanical and 1.9% had infectious complications.
- The findings indicate that real-world rates of these complications are significantly higher than in clinical studies, highlighting the need for careful monitoring and potential additional interventions.
Introduction: The safety and efficacy of a novel family of quadripolar left ventricular (LV) pacing leads designed to pace from nonapical regions of the LV with low pacing capture thresholds was studied in patients undergoing implantation of a cardiac resynchronization therapy defibrillator (CRT-D).
Methods And Results: Patients receiving a CRT-D were implanted with 1 of 3 ACUITY X4 leads (Spiral Long, Spiral Short, or Straight), designed to address coronary venous anatomical variability. Electrical performance and LV lead related complications were evaluated 3 and 6 months post implantation, respectively.
