Why the study?
Does moderate balloon predilation (≤23 mm) reduce the rate of permanent pacemaker implantation compared to larger balloon predilation (25 mm) in patients undergoing TAVI with the CoreValve prosthesis?

Moderate balloon predilation may reduce pacemaker rates after CoreValve TAVI; hypothesis-generating and requires prospective confirmation.
Does moderate balloon predilation (≤23 mm) reduce the rate of permanent pacemaker implantation compared to larger balloon predilation (25 mm) in patients undergoing TAVI with the CoreValve prosthesis?
Using a moderately sized valvuloplasty balloon (≤23 mm) for predilation during TAVI with a CoreValve prosthesis significantly reduces the need for permanent pacemaker implantation without compromising procedural success.
