PATIENT SELECTION

INDICATORS OF HEART FAILURE PATIENTS* WHO MAY BENEFIT
FROM CRT1

Patients with these heart failure indicators: Low LVEF (< 35%) or Wide QRS (> 120 MS) or Frequent RV Pacing (> 40%) should be recommended for an EP consultation.
NYHA I, II, III, IV classes for both heart failure patients and AV block patients using both CRT-D and CRT-P devices.

FDA-Approved indications for medtronic crt devices

ACC, AHA, HRS, AND ESC Guidelines††† support CRT use

See the device instructions for
use for detailed information regarding the procedural instructions, indications, contraindications, warnings, precautions, and potential complications/adverse events.
See www.manuals.medtronic.com for complete labeling.

2013 ACCF/AHA GUIDELINES
FOR CRT1

Benefit for NYHA class I and II patients has only been shown in CRT-D trials, and while patients may not experience immediate symptomatic benefit, late remodeling may be avoided along with long-term HF consequences. There are no trials that support CRT pacing (without ICD) in NYHA class I and II patients. Thus, it is anticipated these patients would receive CRT-D unless clinical reasons or personal wishes make CRT pacing more appropriate. In patients who are NYHA class III and ambulatory class IV, CRT-D may be chosen but clinical reasons and personal wishes may make CRT pacing appropriate to improve symptoms and quality of life when an ICD is not expected to produce meaningful benefit in survival.


*On stable, optimal heart failure medical therapy if indicated.

NYHA Class IV patients should be ambulatory with no admissions for HF in the last month and have a reasonable expectation of survival.

**LBBB = Left bundle branch block.

††Atrioventricular block (AV block) expected to require a high percentage of ventricular pacing that cannot be managed with algorithms to minimize right ventricular pacing.

***Established before implant if indicated, and should be done post-implant.

†††There is no Medicare National Coverage Decision for CRT devices. Only one Medicare Administrative Contractor (MAC) — First Coast Service Options, Inc. responsible for Florida, Puerto Rico, and Virgin Islands — has a policy according to which NYHA class I patients with AV block are not covered. In the absence of a MAC local policy determination, coverage for CRT devices are generally available for all labeled indications. This information is subject to change and the provider has the responsibility to determine medical necessity and to submit appropriate codes and charges for care provided.
