Editorial CommentCommentary: To classify means to choose a threshold.
Classification requires a threshold; however, methods like C-statistic and AUC obfuscate this. Luckily, there is a sensible strategy for imbalanced data thresholding.

ReviewEndovascular repair of intercostal and visceral aortic patch aneurysms following open thoracoabdominal aortic aneurysm repair.
Reoperative open surgical repair (OSR) of thoracoabdominal aortic aneurysms (TAAAs) is associated with high morbidity and mortality. The aim of this study was to analyze outcomes of fenestrated-branched endovascular aneurysm repair (F-BEVAR) for the treatment of intercostal or visceral aortic patch aneurysms after OSR of TAAAs. ⋯ F-BEVAR could be considered as an alternative to reoperative OSR in patients with visceral or intercostal aortic patch aneurysms. This series showed no mortality and a low rate of major adverse events, but a significant need for reintervention.

Elucidating the mechanisms underlying left ventricular function recovery in patients with ischemic heart failure undergoing surgical remodeling: A 3-dimensional ultrasound analysis.
The study objective was to elucidate the mechanisms of left ventricle functional recovery in terms of endocardial contractility and synchronicity after surgical ventricular reconstruction. ⋯ At 6-month follow-up, surgical ventricular reconstruction was associated with significant recovery in global left ventricle function, improved mechanical dispersion indicating a more synchronous left ventricle contraction, and improved left ventricle fiber shortening mostly in the basal region, suggesting the major role of the remote myocardium in enhancing left ventricle functional recovery.

Impact of valve repair on mild tricuspid insufficiency in rheumatic mitral surgery.
Tricuspid valve repair for mild tricuspid regurgitation during rheumatic mitral valve surgery is controversial. We evaluated the benefit of tricuspid valve repair for mild tricuspid regurgitation in rheumatic mitral valve surgery. ⋯ Tricuspid valve repair for mild tricuspid regurgitation in rheumatic mitral valve surgery provides no overt clinical benefit.

Structural abnormalities after aortic root replacement with stentless xenograft.
In complex and high-risk aortic root disease, the porcine Freestyle stentless bioprosthesis (Medtronic Inc, Minneapolis, Minn) is an important surgical treatment option. We aimed to determine prevalence and clinical effect of structural and functional abnormalities after full-root Freestyle implantation. ⋯ Structural and functional abnormalities of the aortic root are frequent after Freestyle implantation and TTE appears to be insufficient for follow-up. Abnormalities might be associated with increased risk of reintervention and potentially adverse clinical outcomes. Longer follow-up and larger study populations are needed to further clarify the clinical implications of abnormalities identified with 4DCT.
