Overview
- Cardiac resynchronization therapy should only be undertaken if the blood pressure is low and if the heart failure medicines have been optimized
- CRT is indicated for symptomatic patients with NYHA III-IV heart failure and wide QRS complex (>120ms) who are him normal sinus rhythm.
- 70% of patients receiving synchronous ventricular contraction report significant symptomatic improvements.
Indications for Cardiac Resynchronization Therapy
1. The left ventricular ejection fraction (LVEF) is ≤ 35%
and
2. There is evidence of left bundle branch block (LBBB) or QRS ≥ 120 msec
and
3. Left ventricular end-diastolic diamter (LVEDD) ≥ 5.5 cms
Background
- Cardiac resynchronization therapy (CRT) is recommended for all patients with LVEF ≤ 35%, dilated LV (LVEDD > 5.5 cm), left bundle branch block (QRS duration > 120 msec), and sinus rhythm. CRT improves functional status and decreases mortality in the majority of these patients.
- In the REVERSE[1] and MADIT-CRT[2] trials patients with NYHA I or II had decreased heart failure events and increased reverse remodeling of the left ventricle. This is not yet an AHA guideline but should be considered in this group of patients based on the available evidence.
ACC/AHA Guidelines- Cardiac Resynchronization (DO NOT EDIT)[3]

Class I1. Patients with left ventricular ejection fraction (LVEF) of less than or equal to 35%, sinus rhythm, and NYHA functional class III or ambulatory class IV symptoms despite recommended, optimal medical therapy and who have cardiac dyssynchrony, which is currently defined as a QRS duration greater than or equal to 0.12 seconds, should receive cardiac resynchronization therapy, with or without an implantable cardioverter defibrillator (ICD), unless contraindicated. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] (Level of Evidence: A) Class IIa1. For patients who have LVEF less than or equal to 35%, a QRS duration greater than or equal to 0.12 seconds, and AF, CRT with or without an ICD is reasonable for the treatment of NYHA functional Class III or ambulatory Class IV heart failure symptoms on optimal recommended medical therapy. (Level of Evidence: B) 2. For patients with LVEF less than or equal to 35% with NYHA functional Class III or ambulatory Class IV symptoms who are receiving optimal recommended medical therapy and who have frequent dependence on ventricular pacing, CRT is reasonable. (Level of Evidence: C) Class IIb1. For patients with LVEF less than or equal to 35% with NYHA functional Class I or II symptoms who are receiving optimal recommended medical therapy and who are undergoing implantation of a permanent pacemaker and/or ICD with anticipated frequent ventricular pacing, CRT may be considered. (Level of Evidence: C) |
