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.  Postoperative mortality and morbidity were comparable, as was valve function at one year.

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:

  • Mild TR:             56%
  • Moderate TR: 19%
  • Severe TR:         5%

Findings:  Along with higher predicted risk, increasing TR severity was associated with increased mortality and readmission.

Should the TR of a certain severity be addressed at the time of TAVR?  How?

This Stanford group retrospectively reviewed their experience over a 10-year period with 293 patients who underwent either limited aortic root repair or root replacement.  

Results:

  • No significant difference in weighted perioperative mortality.
  • No significant difference in weighted survival.
  • However, there was a significantly higher rate of later reoperation in the limited root repair group (11% versus 0%, p<0.001).

The authors present a thorough expert consensus review on the prevention—preoperative, intraoperative, and postoperative—and the postoperative management of sternal wound infections.  The authors conclude with a guideline with class recommendations and levels of evidence.

This article should be in every cardiac surgeon's armamentarium.

This single-center group retrospectively reviewed their experience (2004-2014) with at least two arterial conduits for triple-vessel coronary artery disease to assess the benefit of adding a third arterial conduit versus a venous conduit to the right-sided circulation.  A total of 167 propensity-matched pairs were compared.  In this small study comparing intermediate survival, no benefit of adding a third arterial conduit was appreciated (HR 0.72, p = 0.411).
