Deceleration capacity of heart rate predicts 1-year mortality of patients undergoing transcatheter aortic valve implantation.

ABSTRACT:

Background

Risk prediction in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) is challenging. Development of novel markers for patient risk assessment is of great clinical value. Deceleration capacity (DC) of heart rate is a strong risk predictor in post-infarction patients.

Hypothesis

DC provides prognostic information in patients undergoing TAVI.

Methods

We enrolled 374 consecutive patients with severe AS undergoing TAVI. All patients received 24-hour Holter recording or continuous heart-rate monitoring to assess DC before intervention. Primary endpoint was all-cause mortality after 1 year.

Results

Forty-nine patients (13.1%) died within 1 year. DC was significantly lower in nonsurvivors than in survivors (1
