Does the type of prosthesis influence early left ventricular mass regression after aortic valve replacement? Assessment with magneticresonance imaging

Differences in performance of five types of aortic valve prostheses: haemodynamic assessment by dobutamine stress echocardiography

“…However, there were no differences in LVM reduction between all groups at 1 year, as noted in previous studies 3–6 22–23 28. This may suggest that the haemodynamic advantage of stentless valves, which took longer to implant, did not translate into clinical advantage.…”

Hemodynamic Performance of Stentless Versus Stented Valves: A Systematic Review and Meta-Analysis

“…Eight studies met inclusion criteria 12‐19 . There was excellent agreement between the two reviewers, with a weighted Kappa of 0.9.…”

“…Three trials reported mean gradient values between one and six months postoperatively 13,14,16 . Although confidence intervals were near overlapping amongst the three studies, heterogeneity was present (χ 2 = 8.45, p = 0.01, I 2 = 76.3%).…”

Left ventricular mass regression following aortic valve replacement with mechanical valves

“…The kind of prosthesis used (tilting disc or bileaflet) however did not affect this decrease in the LVMI. Significant LV remodeling occuring early after AVR with porcine bioprosthesis as well as mechanical prosthesis has been observed and the degree of regression in LVMI was independent of the type of prosthesis implanted 14 . However, Bech-Hanssen et.…”
