Why the study?

Does aortic valve replacement with pericardial xenografts improve long-term haemodynamic parameters in patients requiring aortic valve replacement?

Population

30 patients who underwent aortic valve replacement with pericardial xenografts

Comparison

Aortic valve replacement with pericardial… vs Preoperative haemodynamic status

Design

Cohort

Follow-up

mean 43.4 months (range 27 to 59 months)

Authors

Discussion

Member takes

Implication

May support long-term hemodynamic benefits of pericardial xenografts in aortic valve replacement; leaves open comparative durability versus other prostheses.

Structured PICO

Does aortic valve replacement with pericardial xenografts improve long-term haemodynamic parameters in patients requiring aortic valve replacement?

Population

30 patients who underwent aortic valve replacement with pericardial xenografts

Intervention

Aortic valve replacement with pericardial xenografts (sizes 19, 21, 23, 25, and 27 mm annulus diameter)

Comparator

Preoperative haemodynamic status (available in 16 patients)

Outcome

Haemodynamic parameters including cardiac output, pulmonary wedge pressure, left ventricular end-diastolic pressure, and peak systolic gradient at a mean interval of 43.4 monthssurrogate

Aortic pericardial xenografts provide significant long-term circulatory improvement and very small transvalvular gradients.
