Background

Nearly 50% of severe aortic stenosis (AS) patients undergoing transcatheter aortic valve replacement (TAVR) are women, yet they are under-represented in clinical trials. SMART trial reported that in women with small annulus area, self-expanding transcatheter heart valve (THV) showed better hemodynamic outcomes than balloon-expandable THV. In the LANDMARK trial comparing three types of THVs, outcomes in women were investigated.

Methods

In a multicenter, non-inferiority LANDMARK trial (n=768), 369 women with severe AS were randomized to Myval THV series(n=193), Sapien THV series (n=86), and Evolut THV series (n=90). The primary endpoint at 30 days was a composite of all-cause death, all stroke, bleeding (types 3 and 4), acute kidney injury (stages 2-4), major vascular complications, moderate or severe prosthetic valve regurgitation (PVR), and new permanent pacemaker implantation as per the Valve Academic Research Consortium-3 consensus.

Results

Mean age (Myval: 81, Sapien: 81.7, andEvolut 79.8 years old) and median Society of Thoracic Surgeons scores (3.1%,3.5%, 3.1%) were comparable in three arms. More than 50% of women had smallaortic annuli (55.4%, 60.5%, 54.4%). In the Myval arm, 49% of patientsreceived intermediate sizes (21.5, 24.5 and 27.5 mm).
At 30 days, Myval had a lower aortic valve mean pressure gradient (MPG, Myval:8.7mmHg; Sapien: 11.1mmHg, p<0.001) and a higher effective orifice area(EOA) compared to Sapien (1.88cm2, 1.61cm2, p<0.001),while having a higher MPG  (Evolut: 5.4mmHg, p<0.001) and lower EOAthan Evolut (2.37cm2, p<0.001).
Myval was non-inferior to Sapien  (Myval: 19% vs Sapien: 20%, Riskdifference [95%Cl]: -0.6 [NA, 9.6], pnoninferiority=0.01) and Evolut(19% vs 30%; risk difference [95%CI]: -10.9% [NA, 0.1],  pnoninferiority<0.0001)for the primary endpoint. There was no statistically significant differencebetween Myval versus Sapien for itemized events of the primary compositeendpoint, whereas there were lower rates of moderate-severe PVR (Myval 2% vs.Evolut 9%, p=0.01) and major vascular complications (2% vs. 7%, p=0.03) inMyval than Evolut.

Conclusion

In the women subset of the LANDMARK trial, Myvalhad a lower aortic valve mean pressure gradient and a higher effectiveorifice area than Sapien, whereas superior hemodynamics of Evolut to Myvalentails a significantly higher risk of PVR at 30 days.  TAVI withthe Myval series in women patients with severe AS is non-inferior to boththe Sapien and Evolut series for the primary composite endpoint at 30 days.
