Excerpt
The accurate prediction of clinical response to cardiac resynchronization (CRT) remains challenging, despite much work in this area. International guidelines for the use of CRT are currently based solely on the severity of heart failure despite optimal medical therapy, reduced left ventricular ejection fraction (LVEF), electrical dyssynchrony (QRS duration), and atrial rhythm.
1 However, as many as 30-40% of patients who meet patient selection criteria fail to derive clinical benefit following CRT.
