In this manuscript the authors report on the results of a retrospective propensity score analysis in 102 matched pairs of patients, considered to be in a “grey zone” of surgical risk for either TAVI (Edwards Sapiens, Medtronic CoreValve or Symetis Acurate TA prosthesis) or aortic valve replacement (AVR) with a sutureless prosthesis (Sorin Perceal).

In this case report, a patient with aortic stenosis underwent aortic valve replacement. During the procedure, dark pigmentation of the interior aspect of the aorta and sternal joints was discovered, suggesting a rare disorder.

The authors evaluated ventricular function after AR or MR in young patients with regurgitation and preoperative signs of ventricular dysfunction. Results at 18 mos were compared to a normal population. Persistent LV dysfunction was present in 85% after AR+MR and was more common than after either operation alone. Preoperative end-systolic volume pr

The effects of renal failure on outcomes of AVR were examined using CMS data. TAVR pts on dialysis, TAVR pts not on dialysis, and surgical AVR pts on dialysis were compared after propensity score matching. In TAVR patients, dialysis was associated with increased 30 day mortality and survival, and was an independent predictor of worse survival. TAV

This video demonstrates a Florida sleeve valve-sparing aortic root repair, repair of the leaking bicuspid valve with raphe shaving, virtual basal ring annuloplasty and leaflet plication, and ascending through proximal arch replacement with alternate aortic cannulation/clamping.

Patients entered into a clinical trial of TAVR and patients in two registries were evaluated for possible subclinical leaflet thrombosis in their bioprosthetic valves. 40% of the patients in the TAVR trial and 13% of registry patients were found to have such thrombosis. The risk was lower in patients anticoagulated with warfarin. Therpeutic antico

In an interview filmed at the 2015 STS Annual Meeting in San Diego, California, Tom Nguyen speaks with Michael Reardon, Chief of Cardiac Surgery at the Methodist DeBakey Heart & Vascular Center in Houston, TX.

The authors conducted a propensity-matched analysis of outcomes and costs associated with TAVR vs. SAVR procedures in patients considered either intermediate risk (STS PROM 4-8%) or high risk (STS PROM >8%) within the Commonwealth of Virginia.

This study describes activity and outcomes for both standard aortic valve implantation and transcatheter aortic valve implantation (TAVI) in England and Wales in the TAVI era. The study demonstrates that both standard aortic valve implantation and TAVI acitivity have increased since TAVI was first performed in the United Kingdom.
