Computed tomography-based hemodynamic index for aortic dissection.
In this study we aimed to propose a new computed tomography-based hemodynamic indicator to quantify the functional significance of aortic dissection and predict post intervention luminal remodeling. ⋯ The first balance position of luminal pressure difference quantified the hemodynamic status of the dissected aorta. The magnitude of distal shifting of the balance position after intervention was associated with functional improvement and might be used predict longitudinal aortic remodeling.

Surgical explantation of transcatheter aortic bioprostheses: Results and clinical implications.
Despite the rapid adoption of transcatheter aortic valve replacement (TAVR) and worldwide interest in its implantation, TAVR valve explantation has not been well described. ⋯ Surgical TAVR valve explant is increasing and may become common in the near future. The clinical effects of explanting chronically implanted valves with the potential need for aortic repair is not negligible. These data should be used to more appropriately select TAVR candidates as TAVR practices expand into younger and lower risk patients.

Attrition between the superior cavopulmonary connection and the Fontan procedure in hypoplastic left heart syndrome.
We investigated the incidence and predictors of failure to undergo the Fontan in children with hypoplastic left heart syndrome who survived superior cavopulmonary connection. ⋯ In this study spanning more than 3 decades, 8.3% of children with hypoplastic left heart syndrome failed to undergo the Fontan after superior cavopulmonary connection. This attrition rate has not decreased over 30 years. Use of a right ventricle to pulmonary artery shunt at the Norwood procedure was associated with increased attrition.

Radiomics technology for identifying early-stage lung adenocarcinomas suitable for sublobar resection.
Early-stage lung adenocarcinomas that are suitable for limited resection to preserve lung function are difficult to identify. Using a radiomics approach, we investigated the efficiency of voxel-based histogram analysis of 3-dimensional computed tomography images for detecting less-invasive lesions suitable for sublobar resection. ⋯ Voxel-based histogram analysis of 3-dimensional computed tomography images accurately detected early-stage lung adenocarcinomas suitable for sublobar resection.
