A good discussion on the concepts of:

1. aortic true lumen and false lumen behavior after repair of acute Type A aortic dissection
2. distal anastomotic new entry tear after hemiarch repair
3. impact of above on clinical outcomes
4. strategies on preventing distal anastomotic entry tear
 

The authors communicate that improved understanding of these hemodynamic conditions may serve to improve surgical technique, guide creation of novel devices toward new therapeutic targets, reduce surgical risk, and ultimately improve patient outcomes.

On May 25, 2021, Dr. David Heimansohn successfully performed the first surgical implantation of biopolymer Tria™ heart valve in a patient with mitral valve disease at Ascension St. Vincent Hospital, Indianapolis, IN. 

Foldax’s Tria valve is fabricated with a polymeric, silicone-rich polyurethane material intended to resist calcification, improve valve durability, and, most importantly, avoid the need for lifelong anticoagulation.

There are multiple techniques for the repair of supravalvular aortic stenosis (SVAS), but given the rarity of the lesion, analyses comparing the efficacy of each repair is limited.

Septal myectomy leads to excellent symptomatic relief in most patients, and more than 80% report subjective improvement in health status. Important predictors of worsening health included coronary artery disease and poor preoperative health status.

Chronic and prolonged opioid use were independently associated with reduced long-term, disease-specific survival after lung cancer resection. These findings provide epidemiologic support for a biological relationship between opioid use and lung cancer progression.

The goal of this study was to determine underlying case mix factors that can contribute to a plethora of 90-day costs of lobectomy for early-stage lung cancer.

This month's update on the economical and general aspects of the ROOBY-FS trial. The conclusion (on no impact of de novo post-CABG AF on the incidence of stroke nor the 5 year expenditure ) challenges many hitherto perceptions on this frequent compication of coronary surgery.

A large RCT concluding that 'surgical occlusion of the left atrial appendage provides additional protection against stroke when added to anticoagulation.' A number of limitations are briefly discussed. Findings are interesting in that absolute absence of surgical complications has been declared.
