Implication

May support AV optimization in select CRT patients; hypothesis-generating for Doppler-based prediction formulas.

Structured PICO

Does bi-ventricular pacing with AV delay optimization improve cardiac function in a patient with severe congestive heart failure and LBBB?

Population

1 60-year-old Japanese male with dilated cardiomyopathy, severe congestive heart failure (NYHA class III), LVEF 14%, complete left bundle branch block (QRS 172 msec), and prolonged PQ interval (0.22 sec), dependent on intravenous catecholamines.

Intervention

Bi-ventricular pacing with atrioventricular (AV) delay optimization using a Doppler echocardiography formula.

Outcome

Improvement in cardiac function (cardiac output, NYHA class) and relief from dependency on intravenous catecholamines.

Bi-ventricular pacing with AV delay optimization using Doppler echocardiography improved hemodynamics and clinical status in a patient with severe, catecholamine-dependent heart failure.
