A study that reported a durability concern
Hughes coauthored a 71-patient HAART-ring repair series. At mean follow-up of 3.9 years, 11 patients had at least moderate regurgitation, all with trileaflet valves; four needed reoperation, including three for ring dehiscence.
How to interpret this: The authors urged caution with this subannular approach in trileaflet valves. This device-specific cohort should not be generalized to all Duke aortic surgery or all valve-sparing techniques; it is not an individual risk estimate.
Sources: Mid-term outcomes of aortic valve repair using an anatomically shaped internal annuloplasty ring.
