Background: Aortic valve stenosis (AS) is the most common valvular disease. Its surgical indication is undisputed in 83.9; 88.6 and 88.8% at six months, one and two years, respectively. Prior to the procedure, FC was 3.1 ± 0.6, decreasing AS and high surgical risk. (Rev Med Chile 2015; 143: 1512-1520

Redefining the gold standard for aortic valve replacement: Minimally invasive with accelerated recovery Background: Despite being introduced 20 years ago minimally invasive aortic valve replacement is only performed routinely in a minority of patients worldwide. 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.
