There are few instruments to assess patient-centered outcomes after lung transplant.  The authors developed and validated a shortened version of the valued life activities disability scale for this population.  The scale was devised using 140 lung transplant participants and was validated in 84 patients before and after transplant.  The instrument takes only 3 min to complete, has good correlation with longer scales, has good internal consistency, correlates with physiologic parameters, and demonstrates expected improvement comparing before and after transplant states.

This manuscript reports on the 5-year outcomes in the 705 patients with left main (LM) lesions enrolled in the randomized arm of the SYNTAX trial. Follow-up data to 5 years were available in 96.9% of patients who underwent PCI and 92.5% of patients randomized to CABG. Total MACCE at 5 years was 36.9% in patients who received PCI compared with 31.0% in CABG patients (hazard ratio 1.23 [0.95, 1.59]; P=0.12) which was mainly related to differences in repeat revascularization. In the group of patients with high SYNTAX Scores (≥33), MACCE, as well as cardiac death, and revascularization were all significantly increased in patients receiving PCI; whereas stroke and MI occurred at similar rates between treatment arms. The findings suggest that PCI can provide equivalent long-term (to 5 years) death/stroke or MI to CABG, in particular in the subset of LM subjects with SYNTAX Scores <33.

Bauters C, et al. – There are limited data on the prognosis of patients with stable coronary artery disease (CAD) in modern clinical practice. The mortality rate of patients with stable CAD in modern clinical practice is similar to that of the general population and is mostly due to noncardiovascular causes.

 The purpose of this study was to assess the outcome of SA over 5 years and determine predictors for success over that period. This study demonstrated stable results of SA for AF over time with somewhat different predictors for 2– and 5–year NSR in a group of patients with complete follow–up at both time points. Accurate models to determine predictors for success of SA more than 2 years after surgery are essential to better understand long–term outcome for patients with AF.

Authors compared transcatheter aortic–valve replacement (TAVR), using a self–expanding transcatheter aortic–valve bioprosthesis, with surgical aortic–valve replacement in patients with severe aortic stenosis and an increased risk of death during surgery. In patients with severe aortic stenosis who are at increased surgical risk, TAVR with a self–expanding transcatheter aortic–valve bioprosthesis was associated with a significantly higher rate of survival at 1 year than surgical aortic–valve replacement.

Methods

  • Authors recruited patients with severe aortic stenosis who were at increased surgical risk as determined by the heart team at each study center.
  • Risk assessment included the Society of Thoracic Surgeons Predictor Risk of Mortality estimate and consideration of other key risk factors.
  • Eligible patients were randomly assigned in a 1:1 ratio to TAVR with the self–expanding transcatheter valve (TAVR group) or to surgical aortic–valve replacement (surgical group).
  • The primary end point was the rate of death from any cause at 1 year, evaluated with the use of both noninferiority and superiority testing.

 

Results

  • A total of 795 patients underwent randomization at 45 centers in the United States.
  • In the as–treated analysis, the rate of death from any cause at 1 year was significantly lower in the TAVR group than in the surgical group (14.2% vs. 19.1%), with an absolute reduction in risk of 4.9 percentage points (upper boundary of the 95% confidence interval, -0.4; P<0.001 for noninferiority; P = 0.04 for superiority).
  • The results were similar in the intention–to–treat analysis.
  • In a hierarchical testing procedure, TAVR was noninferior with respect to echocardiographic indexes of valve stenosis, functional status, and quality of life.
  • Exploratory analyses suggested a reduction in the rate of major adverse cardiovascular and cerebrovascular events and no increase in the risk of stroke.

In this study the authors looked at the impact of coronary artery disease (CAD) in a single series of 445 patients undergoing TAVI for aortic valve stenosis.  The pre-established primary endpoint of the study was a composite of cardiovascular death, stroke, or myocardial infarction (MI)—at 1 year. Patients were divided into three groups according to the severity of CAD as determined by the SYNTAX score (SS): no CAD, CAD with SS ≤ 22 and CAD with SS >22. At 1-year, increased CAD severity was associated with higher rates of the primary endpoint. This was mainly driven by a difference in cardiovascular death. The risk of stroke and MI was similar in all three groups.

The Flex System is a flexible endoscopic system that enables surgeons to access and visualize hard-to-reach anatomical locations. The system thus promises to extend the benefits of minimally invasive surgery – shorter hospital stays and recovery times – to a broader population of patients. The company initially has targeted the system for use in head and neck surgery, operating through the mouth.
