In this 5-year review covering multiple centers in Australia and New Zealand, the overall major complication rate related to new implanation of a pacemaker or ICD was 8.2%.  Among hospitals performing implants there was a 3-fold range in the incidence of complications, indicating important variations in care quality.

The Throacic Surgery Residents Association (TSRA) Decision Algorithms in Cardiothoracic Surgery is a 100-chapter compendium with an individual algorithm for clinical decisions spanning the entire scope of cardiothoracic surgery. The resource was developed for cardiothoracic surgery residents by residents and cardiothoraicc surgery faculty. The TSRA Decision Algorithms in Cardiothoracic Surgery is fresh off the press and available for purchase on Amazon - https://www.amazon.com/TSRA-Decision-Algorithms-Cardiothoracic-Surgery-e...

In this brief review, the authors elaborate on status quo of the use of endovascular stent grafts in the management of patients with connective tissue disorders. Because the radial force and circumferential stress on the native aorta remains a signficant issue that leads to stent graft failure, open surgical repair remains the gold standard in most of such patients.

Hansson and colleagues analyzed the effect of preoperative dual antiplatelet therapy on outcomes for patients undergoing surgery for acute aortic dissection type A. Among 1,141 patients with acute type A dissection, 108 had aspirin and clopidogrel, and 11 had aspirin and ticagrelor. Dual antiplatelet therapy led to more bleeding and more transfusions but not to more deaths. However, major bleeding was associated with higher mortality. The authors conclude that correct diagnosis is important to avoid dual antiplatelet therapy and reduce bleeding complications in patients with type A dissection.

Yanagawa and colleagues review the current understanding of factors that predict the failure of aortic valve repair. They highlight factors that include unaddressed annular dilatation, residual cusp prolapse, commissural orientation, and the use of patch material, and they note that better understanding of these repair elements results in continually refined techniques that can improve patient outcomes.

Using deep learning employing data from over 700,000 patients (6 billion data points), an algorithm for continuous prediction of the risk of acute kidney injury (AKI) was developed. The model correctly predicted over 90% of AKI requiring dialysis with a lead time of up to 48 hours, with 2 false alerts for every true alert.

In this trial involving over 400 patients, accupuncture was compared to two sham groups and an observation group. The intervention group experienced a nearly two-thirds reduction in the frequency of angina attacks during the 20-week treatment period, significantly better than the sham and observation groups.

In this article, Umana-Pizana et al performed a phases-of-care mortality analysis amongst 5141 cardiac surgery cases with a 4.6% crude mortality in a population with a median STS risk score of 5.8%. They demonstrate that triggers for mortality occured primarily preoperatively (49.3%), followed by in the intensive care unit (23.9%), intraoperatively (13.4%), discharge phase (10.4%), and postoperative floor (3.0%). Importantly, their findings demonstrate that the mortality distribution is bimodal, occuring in those at lowest and highest risk, and they provide targets for areas of improvement and elimination of triggers for mortality in the cardiac surgical patient.

Corsini et al examined the results of a single-institution's 5-year experience of cardiothoracic surgery mock oral examinations. They demonstrate that this time- and labor-intensive exercise where trainees verbalize and practice their certification examination in a safe, controlled environment with their faculty can lead to improvement in preparation for the high-stakes real examination, with an impressive 5-year 100% pass rate for trainees involved in this experience.

These results are encouraging for surgical educators and trainees alike in our quest to better prepare tomorrow's cardiothoracic surgeons for their transition to practice.
