This global, multicenter registry included 2,579 CRT recipients with LVEF ≤ 50% who underwent either LBBAP or conventional biventricular pacing (BVP), with 780 matched pairs analyzed. Over a mean follow-up of 34 ± 15 months, LBBAP significantly reduced the combined endpoint of all-cause death or first heart failure hospitalization (22.2% vs 30.8%; HR 0.81; P≈0.048), largely driven by fewer HF hospitalizations (13.6% vs 20.8%; HR 0.63; P<0.001). Patients in the LBBAP arm also experienced shorter paced QRS duration (129 vs 143 ms) and fewer procedural complications (3.5% vs 6.5%; P=0.004). Mortality rates were similar between groups, reinforcing LBBAP's safety and potential efficacy for CRT in this patient population.

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
