A medium-size RCT comparing full sternotomy to limited sternotomy for conventional aortic valve replacement, presented at the SCTS Annual Meeting in Glasgow. The 7-10% one year attrition rate seems quite disappointing, and will most probably be discussed. We will await the full paper to see what was the learning curve for the innovative approach.

The authors studied 852 adults with bicuspid aortic valves. The prevelance of three morphotypes was tallied. Relative fusion rates were: RL 72.9%, RN 24.1% and LN 3%. Additionally, 18.3% had no raphe. Aortic regurgitation was unrelated to morphotype. Aortic stenosis was more common in the RN fusion group and in the presence of a raphe. Seventy-

The authors retrospectively reviewed their minimally invasive aortic valve replacement experience over a three-year period to assess the outcomes in patients undergoing conventional knot tying (n = 39) versus automated knot tying with the Cor-Knot device (n = 53). Aortic cross-clamp time was approximately 10 minutes shorter in the latter group. Pos

The STS/ACC TAVR Registry was analyzed to determine the effect of tricuspid regurgitation (TR) on outcomes after transcatheter aortic valve replacement (TAVR). The authors found that TR, of any severity, is quite common in TAVR patients (80%). The breakup of TR severity was as follows:

A succinct, readable, and well-referenced editorial on extending criteria for surgery on bicuspid aortopathy below the threshold of 4.5 cm diameter. It is even more interesting in the era of increasing industry pressure for transcatheter aortic valve replacement.
