A machine learning approach for predicting complications in descending and thoracoabdominal aortic aneurysms.
To use machine learning to predict rupture, dissection, and all-cause mortality for patients with descending and thoracoabdominal aortic aneurysms in an effort to improve on diameter-based surgical intervention criteria. ⋯ This study provides surgeons with a more accurate, machine learning-based, risk-stratification metric to predict complications for patients with descending aortic aneurysms.

Total ventricular mass oversizing +50% or greater was a predictor of worse 1-year survival after heart transplantation.
Current donor-recipient size matching guidelines rely primarily on body weight, with no specified oversizing cutoff values. Recent literature has explored predicted total ventricular mass matching over body weight matching. We aim to explore the impact of total ventricular mass oversizing on heart transplant outcomes. ⋯ Total ventricular mass mismatch greater than +50% is associated with worse 1-year survival, although this group comprises a small portion of heart transplant. total ventricular mass mismatch from +30% to +50% is not associated with worse survival. These outcomes should be considered in selecting donors and in efforts to expand the potential donor pool.

Fate of Transposition of the Great Arteries with Pulmonary Stenosis After Double-Root Translocation, Rastelli, and Réparation à l'Etage Ventriculaire.
For transposition of the great arteries with unrestricted ventricular septal defect and pulmonary stenosis, double-root translocation is reported to reconstruct ideal double artery roots with growth potential. However, prospective long-term studies describing the long-term outcomes are still scarce. Therefore, the aim was to assess development of double artery roots, hemodynamics, and freedom from death and heart failure 17 years after double-root translocation, Rastelli, and Réparation à l'Etage Ventriculaire procedures. ⋯ By reconstructing ideal double artery roots, double-root translocation can provide postoperative long-term excellent hemodynamics and minimal death and heart failure for patients with transposition of the great arteries/ventricular septal defect/pulmonary stenosis.
