Minimally invasive aortic valve replacement (AVR) benefits avoiding sternal wound complications, prolonged hospitalization and reduced postoperative pain has been widely reported. The benefits of a small sternal incision in obese patients decreases the potential risk of sternal dehiscence otherwise present on a conventional sternotomy. Here we report the case of a 76-year-old woman with moderate obesity who was referred to our institution with severe degenerative aortic stenosis. She underwent aortic valve replacement with a novel technique for annulus enlargement through upper ministernotomy.
