Propensity score matching was applied to match patients into LBBP\u2010CRT group and BiV\u2010CRT group.

The QRS duration (QRSd) was narrowed from 167.7\u2009\u00b1\u200914.9 ms to 111.7\u2009\u00b1\u200912.3 ms (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.0001) in the LBBP\u2010CRT group and from 163.6\u2009\u00b1\u200913.8 ms to 130.1\u2009\u00b1\u200914.0 ms (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.0001) in the BiV\u2010CRT group. A trend toward better left ventricular ejection fraction (LVEF) was recorded in the LBBP\u2010CRT group (50.9\u2009\u00b1\u200910.7% vs 44.4\u2009\u00b1\u200913.3%, <jats:italic>P<\/jats:italic> = .12) compared to that in the BiV\u2010CRT group at the 6\u2010month follow\u2010up. A trend toward better echocardiographic response was documented in patients receiving LBBP\u2010CRT procedure (90.5% vs 80.9%, <jats:italic>P<\/jats:italic> = .43) and more super CRT response was documented in the LBBP\u2010CRT group (80.9% vs 57.1%, <jats:italic>P<\/jats:italic> = .09) compared to that in the BiV\u2010CRT group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>LBBP\u2010CRT can dramatically improve the electrical synchrony in heart failure patients with LBBB.
