Aortic valve disease

A nice short demonstration from Michael Mack of his cannulation technique for minimally invasive AVR with femoral vein cannulation

In a roundtable filmed at the 2015 EACTS Annual Meeting in Amsterdam, Marjan Jahangiri and Mattia Glauber share perspectives on the evolution and current state of aortic valve replacement surgery.

The authors propose a novel method of prosthesis sizing, using newly designed sizers and coaptation forceps, which simplifies the steps for the re-implantation of the tricuspid aortic valve.

The investigators in this registry study enrolled 3815 patients with asymptomatic aortic stenosis. Patients underwent either surgical aortic valve replacement (AVR) or conservative therapy. In order to increase comparability, they used propensity score matching to create two more similar groups.

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

Dr. Michael Mack. Patient Background: 49 year old male, Sever Aortic Stenosis with BicuspidAortic Valve, Normal LV with 60 mmhg peak gradient, Valve area- 0.79 cm2, Moderate Aortic Insufficiency, Minimally Invasive Aortic Valve Replacement with a 25 mm Edwards Magna Tissue Valve.

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.
