Resumen

TURNER, Eduardo et al. Redefining the gold standard for aortic valve replacement: Minimally invasive with accelerated recovery. Rev. méd. Chile [online]. 2021, vol.149, n.4, pp.508-513. ISSN 0034-9887.  http://dx.doi.org/10.4067/s0034-98872021000400508.

Background:

Despite being introduced 20 years ago minimally invasive aortic valve replacement is only performed routinely in a minority of patients world-wide.

Aim:

To report the operative outcome of minimally invasive aortic valve replacement done through a partial upper sternotomy.

Patients and Methods:

Retrospective analysis of data recorded prospectively of 450 consecutive patients with a median age of 66 years (59% males) who had a minimally invasive aortic replacement.

Results:

79% of patients had aortic stenosis. Cross clamp/cardiopulmonary bypass times (median) were 56 and 68 minutes respectively. Conversion to full sternotomy was required in 2.6% of patients, reoperation for bleeding in 2.9%. 1.6% suffered a stroke and 19% postoperative atrial fibrillation. 0.9% required a permanent pacemaker. Postoperative mortality was 0.9%. Median postoperative hospital stay was six days.

Conclusions:

Minimally invasive aortic valve replacement can be performed with satisfactory results.
