This is a retrospective review of 143 patients requiring reoperation after an initial AVR with a Freestyle® stentless bioprosthesis. Valve survival was 10.4 years for those with structural valve deterioration, but it was much less (4.1 years) if the initial procedure was for infective endocarditis. Operative mortality was <2%.

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 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.
