New pacemaker strategy could cut heart failure deaths after valve surgery

This study looks at whether a special type of pacemaker, called cardiac resynchronization therapy (CRT), can help people with heart failure who develop a heart block after having their aortic valve replaced. The trial will include 360 adults who have a new, persistent heart block and moderately reduced heart function after a successful valve procedure. The goal is to see if early use of this pacemaker reduces the chance of being hospitalized for heart failure or dying within a year.
