Mild-to-moderate functional tricuspid regurgitation in patients undergoing mitral valve surgery.
The decision to repair mild-to-moderate functional tricuspid regurgitation (TR) during mitral valve surgery remains controversial. We evaluated the effects of tricuspid valve (TV) repair for functional mild-to-moderate TR during mitral valve surgery. ⋯ Early or late clinical benefits of concomitant TV repair for mild-to-moderate TR during mitral valve surgery were uncertain through a long-term follow-up of 959 patients. Several preoperative factors and the performance of Maze procedure for AF seem to be more important than TV repair in overall clinical outcomes.

Knowledge, attitudes, and practice patterns in surgical management of bicuspid aortopathy: a survey of 100 cardiac surgeons.
Clinical practice guidelines have been established for surgical management of the aorta in bicuspid aortic valve disease. We hypothesized that surgeons' knowledge of and attitudes toward bicuspid aortic valve aortopathy influence their surgical approaches. ⋯ This large survey uncovered significant gaps in the knowledge and attitudes of surgeons toward the diagnosis and management of bicuspid aortopathy, many of which were at odds with current guideline recommendations. Efforts to promote knowledge translation in this area are strongly encouraged.

Radiologic evaluation for volume and weight of remnant lung in living lung donors.
Living-lung donors lose pulmonary function of a right or left lower lobe in exchange for a noble donation; however, Chen and colleagues reported postoperative pulmonary function of the donors was significantly better than the estimated values. The purpose of this study was to investigate if the improvement of postoperative pulmonary function is associated with hypertrophic phenomena of remnant lung. ⋯ Hypertrophic change of the ipsilateral remnant lung may be recognized in living lung donors.

Observational StudyMicrocirculation and its relation to continuous subcutaneous glucose sensor accuracy in cardiac surgery patients in the intensive care unit.
Continuous glucose monitoring could be helpful for glucose regulation in critically ill patients; however, its accuracy is uncertain and might be influenced by microcirculation. We investigated the microcirculation and its relation to the accuracy of 2 continuous glucose monitoring devices in patients after cardiac surgery. ⋯ The results of the present study have shown acceptable accuracy for both sensors in patients after cardiac surgery. The microcirculation was impaired to a limited extent compared with that in patients with sepsis and healthy controls. This impairment was not related to sensor accuracy but the peripheral temperature for both sensors and patient age and Acute Physiology and Chronic Health Evaluation IV predicted mortality for the Navigator were.

Aortic root conservative repair of acute type A aortic dissection involving the aortic root: fate of the aortic root and aortic valve function.
Despite many studies about aortic valve function and aortic root geometry after conservative aortic root repair of acute type A aortic dissection, the results are not always consistent or conclusive. This study aims to evaluate aortic root diameter and aortic valve function after surgery for acute type A aortic dissection involving the aortic root. ⋯ Conservative aortic root repair of acute type A aortic dissection demonstrates acceptable long-term clinical outcomes. However, more aggressive approaches should be considered for patients who have aortic root dilatation because of the risk of developing a root aneurysm after surgery.
