“Device landing zone” calcification, assessed by MSCT, as a predictive factor for pacemaker implantation after TAVI
Why the study?
Does device landing zone calcification assessed by MSCT predict the need for pacemaker implantation after TAVI in patients with severe aortic stenosis?

Implication
Device landing zone calcification was associated with post-TAVI pacemaker need; supports prediction models but requires prospective validation before clinical use.
Structured PICO
Does device landing zone calcification assessed by MSCT predict the need for pacemaker implantation after TAVI in patients with severe aortic stenosis?
P
Population
81 consecutive symptomatic patients with severe aortic stenosis scheduled for trans-catheter aortic valve implantation (TAVI) using the CoreValve prosthesis.
I
Intervention
Preprocedural multislice cardiac computed tomography (MSCT) assessment of calcification load in the device landing zone (DLZ).
O
Outcome
Need for post-TAVI pacemaker implantation.hard clinical
Preprocedural CT assessment of device landing zone calcification, combined with clinical factors like female sex and depressed EF, can effectively predict the need for pacemaker implantation after TAVI.
