His bundle pacing in a patient with CHF and LBBB resulted in dramatic clinical improvement over 27 months, with NYHA class improving from IV to I and ejection fraction increasing from 28% to 50%.
Case Report (n=1)
Physiologic Resynchronization Therapy. This is a case of a patient with congestive heart failure and left bundle branch block who was referred for cardiac resynchronization therapy implantation. Instead, a His bundle pacing was achieved with a narrow QRS complex. During 27 months of observation, the patient improved dramatically from NYHA class IV to I. Echo parameters improved significantly the LV diameter from 75/50 to 60/40 mm, EF from 28 to 50%, and mitral regurgitation from 4 to 2°. (J Cardiovasc Electrophysiol, Vol. 22, pp. 813-817, July 2011)
Dąbrowski et al. (Thu,) conducted a case report in Congestive heart failure and left bundle branch block (n=1). His bundle pacing was evaluated on NYHA class and echocardiographic parameters (LV diameter, ejection fraction, mitral regurgitation). His bundle pacing in a patient with CHF and LBBB resulted in dramatic clinical improvement over 27 months, with NYHA class improving from IV to I and ejection fraction increasing from 28% to 50%.
