When to intervene the pulmonary artery: Importance of anatomical assessment in the diagnosis of pulmonary artery coarctation.
Pulmonary artery coarctation (PACoA) is a major problem that increases the frequency of intervention. However, there is little evidence regarding the prediction of PACoA development. ⋯ Uneven PA branching rather than the ductus arteriosus size was strongly associated with PACoA development; therefore, morphologic assessment by contrast-enhanced computed tomography should be considered in patients with pulmonary atresia.

Right heart failure and patient selection for isolated tricuspid valve surgery.
To characterize patients with right heart failure undergoing isolated tricuspid valve surgery, focusing on right heart morphology and function. ⋯ The cluster analysis of patients with right heart failure undergoing isolated tricuspid valve surgery separated functional and structural tricuspid valve disease. Good early outcomes suggest expanding criteria for tricuspid valve surgery and earlier intervention for functional TR with right heart failure.

Ex vivo biaxial load testing analysis of aortic biomechanics demonstrates variation in elastic energy distribution across the aortic zone zero.
We hypothesized that tissue characteristics vary significantly along zone zero, which may be reflected by regional differences in stored elastic energy. Our objectives were to (1) characterize the regional variation in stored elastic energy within tissues of the aortic zone zero and (2) identify the association between this variation and patient characteristics. ⋯ Aortic tissue biomechanical metrics varied across regions and with patient characteristics within the aortic zone zero. Assessment of endovascular outcomes in the ascending aorta must closely consider the region of deployment and variable tissue qualities along the length of the landing zone. Regional variation in tissue characteristics should be incorporated into existing patient-specific models of aortic mechanics.

Our multidisciplinary cardiac tumor team now has an experience of operating on 122 cases of primary cardiac sarcoma over a 23-year period. The purpose of this study is to present our short- and long-term outcomes for cardiac sarcoma. ⋯ Management of these complex patients can show reasonable outcomes in centers with a multidisciplinary cardiac tumor team. Mortality has not improved with time and is likely related to the systemic nature of this disease.
