Arrhythmias clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Medico-economic Evaluation of Strategies for the Lead Extraction of Implantable Defibrillator and Pacemakers

GAINE LASER

Start date: March 2015
Phase: N/A
Study type: Observational

The growing use and the expanding indications for cardiovascular implantable electronic devices (CIEDs) have been associated to an increase of device removal. The indications of CIEDs removal are infectious (55%) or noninfectious (45%) such as upgrading of devices, nonfunctional devices and thrombosis. Removal can be performed according to transvenous or surgical procedures. Transvenous lead removal (TLR) must be done by experimented cardiologists and respecting current consensus. TLR can be done with conventional techniques involving inserting locking stylets and telescoping sheaths around the pacing leads to separate them from the surrounding scar tissue. These conventional procedures have a success rate of ≈65%. TLR thanks to laser sheath has been validated and improved the success rate until >95%. However, the TLR from chronically implanted CIEDs still carries a significant risk of procedural failure, morbidity, and mortality, related to tearing of the great vessels and cardiac structures, even when performed by experienced operators. Even if the transvenous extraction using laser sheath seems to be more effective, this strategy would be more expensive. Considering the availability of several strategies for TLR and the cost heterogeneity of procedures, a cost assessment in real life of these therapeutic strategies is essential for an optimal choice of therapeutic strategies.
