These incredible findings are the results of an analysis of the New York State Department of health statewide planning and research cooperative database. 

these represent operations from 1995 to 2014 and represent over 99000 major lung resections. Surgeons performing more than 30 lobectomies per year have a mortality of 1% and surgeons performing less than 12 per year have a mortality of 2.8%. 

But the most surprising fact is that the low volume surgeons performed 90% of  the lobectomies. 

Do you agree with the results of this very large study and if you do what do you think should happen about this ?

The association of cardiovascular events and all-cause mortality with optimism was assessed in this metaanalysis.  Optimism was associated with a decreased risk of cardiovascular events (ROR 0.65) and a decrease in all-cause mortality (RR 0.86).  Mechansims have yet to be identified.

Propensity score model comparing MitraClip vs. surgery in low-intermediate risk elderly patients with degenerative mitral regurgitation.  Short term survival was better with MitraClip whereas longer term survival better with surgery.  The study emphasis the importance of longer term follow-up.

Reporting of postmarket outcomes for the Sapien 3 and Mitraclip devices frequently misclassified patient deaths as device malfunction or other outcomes.  Misclassification for Sapien 3 involved 17.5% of patients deaths, and involved 24.7% of patient deaths for Mitraclip.  These outcomes are important for the public and physicians to understand when discussing risks and benefits of such devices.

David Taggart, MD, PhD (University of Oxford, England), the chairman of the EXCEL surgical committee during the design and recruitment phase of the trial, believes the investigators downplayed the increased risk of all-cause mortality with PCI and oversold the reduced risk of the study’s primary composite endpoint of death, stroke, and MI, particularly since the benefit was largely driven by a higher risk of periprocedural MIs in the CABG arm. 

“I found it worrying that there seemed to be a strong signal here and I don’t think that was accurately reflected in the New England Journal of Medicine paper,” Taggart told TCTMD. “We’re not talking about two tablets for a headache. We’re talking about people dying. The data are the data, and that’s what the data show.

Ex vivo lung perfusion was used in 25% of transplanted lungs in the Toronto program since 2008. This resulted in an increase in the number of transplanted patients without any degradation of long-term outcomes, including survival and freedom from chronic dysfunction.

The authors investigated cusp size in patients undergoing aortic valve repair for valve regurgitation. They found that most patients with small cusps have annulus cusp mismatch. They suggested that small cusp size is not a contraindication in aortic valve repair and recommended to secure annulus by plications to correct annulus cusp mismatch.

In this paper, the objective was to find out the echocardiographic predictors of reoperation for subaortic stenosis. Among 82 patients who initially underwent subaortic stenosis corrective surgery, 30 patients required reoperation. The risk factors were young age, unfavorable left ventricular geometry, interrupted aortic arch, and higher residual left ventricular outflow tract gradient.
