This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
When doctors replace a narrowed aortic valve using a catheter-based procedure, some patients develop new heart rhythm or electrical conduction problems. This study is investigating whether these problems go away on their own or persist, and whether patients need a pacemaker to help their heart work properly. Researchers will perform specialized heart electrical tests and continuous heart monitoring to find answers.
Doctors don't yet have clear guidelines on how to treat these heart electrical problems when they happen after this procedure. Some may resolve without treatment, while others might require a pacemaker. This study will help doctors understand who needs a pacemaker and who can safely be monitored without one.

Within 3–7 days after your valve procedure, you'll have a specialized heart electrical test (electrophysiology study) to see if you need a pacemaker. If the test shows you need one, you'll receive a pacemaker implant and wear a portable heart monitor for 4 weeks, then have a repeat electrical test 30–45 days later. If the test shows you don't need one, you'll simply wear a portable heart monitor for 4 weeks and attend follow-up visits to make sure no problems develop.
