The effect of PPM in mechanical prostheses on long-term survival is not well-established. Patients who received a 21 mm or smaller aortic valve between 2000 and 2011 were retrospectively analyzed ( = 416). Propensity matching was used in order to account for baseline differences in patient subgroups...
