![]() Poor lead positioning (i.e., left ventricular lead is apically paced or near a large scar).Ĭoncerns about patient nonresponse to CRT have spurred an investigation into new approaches to deliver CRT, including using CRT via conduction system pacing, which may be achieved with His bundle pacing or left bundle branch area pacing, using new device-based algorithms to improve fusion of pacing with intrinsic conduction, and leveraging data from device-based sensors as part of remote monitoring.Inadequate atrioventricular or ventricular-ventricular intervals.Competing atrial or ventricular rhythms reducing BVP proportion.Lack of 99% manifest BVP (check pacing thresholds).Patient selection (non-LBBB pattern, QRS not very wide, etc.).5 These may potentially include but are not limited to the following: 4 A myriad of etiologies should be investigated to address nonresponse. A strategy for BVP is needed, and this may require atrioventricular nodal ablation if pacing is incomplete (<90-95%).Ī patient who is not responding to CRT is defined as an individual who experiences disease progression from HF despite the attempted application of BVP. CRT should be considered in patients with HFrEF and an LVEF ≤35% in NYHA class III or IV if they are in atrial fibrillation and have an intrinsic QRS ≥130 msec.CRT should be considered in symptomatic patients with HFrEF who have been optimized on GDMT, have an LVEF ≤35%, and are in sinus rhythm with a QRS ≥150 msec and non-LBBB pattern.CRT should be considered in symptomatic patients with HFrEF who have been optimized on GDMT, have an LVEF ≤35%, and are in sinus rhythm with a QRS of 130-149 msec in an LBBB pattern.CRT is indicated in patients with heart failure with reduced ejection fraction (HFrEF) who have been optimized on guideline-directed medical therapy (GDMT) (i.e., doses have been titrated to either target doses or maximally tolerated doses of GDMT as per clinical guidelines) and have a left ventricular ejection fraction (LVEF) ≤35%, remain symptomatic (New York Heart Association class II-IV symptoms), and are in sinus rhythm with a QRS >150 msec in an LBBB pattern.Still, a broad overview of the indications is listed below for the purposes of this article. The society guidelines for CRT can be reviewed for nuances regarding the indications for CRT. Indications for Cardiac Resynchronization Therapy ![]() CRT is traditionally delivered via a three-lead pacing system to perform biventricular pacing (BVP), with wires placed into the right atrium, right ventricle, and a branch of the coronary sinus, with the goal of achieving >99% pacing. ![]() CRT is unique among cardiovascular therapeutics in that it also improves mortality in select patients, particularly those whose HF is driven by dyssynchrony from conduction delays that manifest as wide QRS interval, especially in the setting of a left bundle branch block (LBBB). The program plans to apply for CACREP accreditation as soon as the application is allowed (once the program has produced its first graduates).What is Cardiac Resynchronization Therapy?Ĭardiac resynchronization therapy (CRT) is a pacing therapy for patients with heart failure (HF), which is prescribed to improve symptoms, promote favorable ventricular remodeling, and reduce the risk of HF hospitalization. *The master's in counseling programs are aligned with the standards and competencies of the Council for the Accreditation of Counseling and Related Educational Programs (CACREP), which adds merit and verifies the quality of your degree for future employers.
