This study examined data that suggested off-pump coronary artery bypass (OPCAB) may carry a higher risk of mortality in the long term than on-pump coronary artery bypass (ONCAB).

This study focused on the anatomical evolution of residual aortic dissection after type A repair. To improve long-term outcomes, early demographic and anatomic poor prognostic factors that were identified in this study should be considered for more aggressive treatment at an early phase.

In contrast to traditional risk assessment methods (logistic regression), which assume that risk factors interact linearly and additively, the non-linear machine learning methodology of Optimal Classification Trees provides superior power for predicting risks after congenital heart surgery, with the advantage over other machine learning methods of logical interpretability. This methodology also allows estimation of individual patient risk, based on aggregate database data, and may facilitate decision–making and quality improvements in congenital heart surgery.

Norwood palliation for hypoplastic left heart syndrome typically results in retrograde perfusion of the native aortic root. This may predispose to native aortic root thrombosis (NART).

This article presents the assessment of long-term outcomes of patients treated by anatomical pulmonary resection with the video-assisted thoracoscopic surgery (VATS) approach, VATS requiring intraoperative conversion to thoracotomy, or an upfront open thoracotomy for lung cancer surgery. The study found that VATS is favored when possible.

On July 22, The Annals of Thoracic Surgery published this consensus statement on nomenclature and classification of the congenital bicuspid aortic valve (BAV) and Its aortopathy.  

This consensus statement divides BAV into 3 types:  1) Cusp-fused type (right-left, right-non and left-non-coronary cusp fusion ); 2) Two-sinus type (latero-lateral and antero-posterior ); and 3) Partial-fusion (forme fruste) type.

BAV-associated aortopathy are categorized into 3 types: 1) Ascending type; 2) Root type; and 3) Extended type.

This study assessed cognitive involved in cardiac surgical procedures from the perspective of three different specialty groups: surgeons, anesthesiologists, and perfusionists.  The 137 unique processes that were identified were classified as: decision points, critical communications, pitfalls, and strategies.  Understanding these processes and the different perspectives each team member brings to the operation may help improve patient safety and outcomes.

This study analyzes the relocation of both papillary muscles to correct FMR in both ICM and DCM. The results demonstrate very satisfactory in-hospital and 1-year outcomes.

In this article, Dr. Sandhu et al. review their 22-year experience in managing patients with thoracic aortic graft infection. They demonstrate that this infection is highly morbid and requires prompt antimicrobial coverage, debridement, graft replacement, and vascularized graft coverage to prevent morbidity and mortality.

In this article, Dr. Farber et al. describe the acceptable five year outcomes of using the Conformable GORE® TAG® thoracic endoprosthesis (CTAG) device (W.L. Gore and Associates, Flagstaff, AZ) for thoracic endovascular repair (TEVAR) of blunt aortic injuries in a prospective, single-arm study among 111 patients.
