Lung Resection After Initial Nonoperative Treatment for Non-Small Cell Lung Cancer.
The study objectives were to assess the outcomes of lung resection in patients with non-small cell lung cancer previously treated with nonoperative treatment and to identify prognostic factors associated with survival. ⋯ In this selected, heterogeneous population, lung resection after initial nonoperative treatment for non-small cell lung cancer was safe. Surgery as local consolidative therapy was associated with encouraging outcomes and should be considered for these patients.

To investigate outcomes after aortic root allograft reoperation, identify risk factors for morbidity and mortality, and describe practice evolution since publication of our 2006 allograft reoperation study. ⋯ Aortic root allograft reoperations present a technical challenge but can be performed with low mortality and morbidity. Radical explant offers outcomes similar to AVR-only while allowing for implant of larger prostheses. Increasing experience with allograft reoperations has permitted excellent outcomes; thus, risk of reoperation should not dissuade surgeons from using allografts for invasive aortic valve infective endocarditis and other indications.

Four Decades of Progress in Heart-Lung Transplantation: 271 Cases at a Single Institution.
The objective of this study is to evaluate survival for combined heart-lung transplant (HLTx) recipients across 4 decades at a single institution. We aim to summarize our contemporary practice based on more than 271 HLTx procedures over 40 years. ⋯ Long-term survival in HLTx is achievable with institutional experience and may continue to improve in the coming decades. Advances in mechanical circulatory support, improved maintenance immunosuppression, and early recognition and management of acute complications such as primary graft dysfunction and acute rejection have dramatically improved the prognosis for recipients of HLTx in our contemporary institutional experience.

Impact of Timing of Urgent Coronary Artery Bypass Grafting Following Coronary Angiography on Acute Kidney Injury.
Prior studies have examined the association between timing of cardiac surgery after coronary angiography with risk of acute kidney injury, but this remains controversial. The purpose of this study was to investigate the association between interval from coronary angiography to urgent coronary artery bypass grafting with acute kidney injury, and to examine this possible effect in patients with preexisting kidney disease. ⋯ For patients undergoing urgent coronary artery bypass grafting, there is a decreased risk of kidney injury in those having surgery on day 3 after coronary angiography compared with those having surgery on Day 0 to 1, regardless of preexisting kidney disease.

Outcomes of Quantitative Flow Ratio Based Functional Incomplete Revascularization after Coronary Artery Bypass Grafting Surgery.
Quantitative flow ratio is a novel functional assessment tool of coronary diseases. Whether quantitative flow ratio could improve the outcomes of coronary artery bypass grafting is undetermined. This study aimed to investigate the association between the quantitative flow ratio based functional incomplete revascularization and the outcomes after coronary artery bypass grafting surgery. ⋯ Both the functional incomplete revascularization and anatomic incomplete revascularization were associated with increased risks of 12-month major adverse cardiac or cerebral vascular events after coronary artery bypass grafting surgery. The quantitative flow ratio can serve as a supplementary tool for the decision-making of surgical revascularization.
