Figure 3. Average LVEF from implant to follow-up for baseline LVEF between 35% and 50% vs. LVEF <35%.
Both HFrEF and HFmrEF exhibited significant improvements in LVEF after LBBAP.
LVEF, left ventricular ejection fraction; HFmrEF, heart failure with mildly reduced ejection fraction ; HFrEF, heart failure with reduced ejection fraction.
