Implantation of Defibrillator with Biventricular Resynchronization System

Cardiac resynchronization therapy – a treatment option to be considered for select patients with refractory congestive heart failure.

OBJECTIVES:

Improvement of functional class (quality of life) in patients who are in an extreme situation and have predominantly nonsegmental (ischemic) cardiopathy.

INCLUDES PATIENTS:
  • Excluded / Heart transplant
  • Refractory Heart Failure (Functional class III / IV NYHA)
  • Left Ventricular Ejection Fraction ≤ 30 – 35%
  • Left Bundle Branch Block (QRS ≥ 150 mS)
  • Echographic determination (myocardial contractility / A-V interventricular and intraventricular synchrony)
ACCESS ROUTES
  • Triple percutaneous puncture of left subclavian vein
  • Right atrial electrode (atrium)
  • Right ventricular electrode (apex)
  • Left ventricular electrode (epicardial)
  • Access to coronary sinus
  • Phlebogram (coronary sinus and coronary veins)
  • Selection of the proper vein
  • Proper synchronization
  • RV / LV – Activation times
AUTOMATIC IMPLANTABLE STIMULATOR DEVICES / CARDIOVERTERS / DEFIBRILLATORS / Resynchronizers (AID + CRT)
  • Single chamber (more frequent)
  • Dual chamber: used if:
    • A-V synchrony necessary
    • Atrial contraction
    • Coadjuvant treatment / Heart failure
  • Triple chamber (more frequent / with biventricular resynchronization therapy)
