Multicenter Study Clinical TrialDissected Aorta Repair Through Stent Implantation trial: Canadian results.
We describe the Canadian results of the Ascyrus Medical Dissection Stent (AMDS), a novel partially uncovered aortic arch hybrid graft implanted antegrade during hypothermic circulatory arrest to promote true lumen expansion and enhance aortic remodeling. ⋯ Preliminary results suggest that the AMDS is a safe, feasible and reproducible adjunct to current surgical approaches for acute DeBakey I aortic dissection repair. Further, the AMDS manages malperfusion and promotes early positive remodeling in the aortic arch and distal dissected segments, with favorable FL closure rates at follow-up. Ongoing follow-up will provide additional insight into the long-term effects of the AMDS.

Cluster analysis of preoperative echocardiographic findings and outcomes following left ventricular device implantation.
To investigate whether preoperative echocardiography findings determine postoperative continuous-flow left ventricular assist device outcomes. ⋯ Clustering demonstrated the importance of preoperative TR in predicting RVF. Combined severe LV and RV failure with severe MR and TR portends the worse prognosis.

Carinal surgery: A single-institution experience spanning 2 decades.
Complete resection of neoplasms involving the carina are technically challenging and have high operative morbidity and mortality. This study examines the last 2 decades of clinical experience at our institution. ⋯ Despite advances in perioperative management, carinal resection poses challenges for both patient and surgeon. Preoperative chemotherapy, radiation, and concomitant pulmonary resection were associated with increased risk of complications. Patient selection and meticulous surgical technique contribute to reduction in morbidity and mortality.
