Minimally invasive approaches to mitral valve repair have demonstrated equivalent technical outcomes and more rapid recovery when compared with traditional sternotomy. These techniques have been widely accepted for mitral insufficiency and stenosis. The utilization of minimally invasive techniques in the presence of left ventricular (LV) dysfunction has been controversial. We hypothesized that minimally invasive mitral valve surgery could be safely performed in the presence of compromised myocardial function, thereby minimizing recovery time. ⋯ Minimally invasive, port-access, mitral valve surgery can be safely performed with minimal morbidity and mortality in the presence of cardiomyopathy. This approach may be considered in patients with isolated mitral valve pathology and LV dysfunction in an experienced center.

A 16-year-old adolescent boy sustained traumatic bronchopleural fistula, refractory to conventional management, which was treated successfully with differential lung ventilation and extracorporeal membrane oxygenation support. This case highlights a novel approach for managing traumatic bronchopleural fistula in children.

Previous studies have suggested that early surgery after coronary angiography may be associated with the risk of acute kidney injury (AKI) in cardiac surgery with cardiopulmonary bypass. However, the effect of coronary angiography on the risk of AKI after off-pump coronary artery bypass graft surgery (OPCABG) remains uncertain. ⋯ The risk of postoperative AKI was not related to the time between coronary angiography and OPCABG. These findings suggest that delaying elective OPCABG after coronary angiography owing to the sole concern for renal function may be unnecessary.

Randomized Controlled Trial Comparative Study
Segmentectomy versus wedge resection for non-small cell lung cancer in high-risk operable patients.
Patients with early-stage lung cancer and limited pulmonary reserve may not be appropriate candidates for lobectomy. In these situations, sublobar resection (wedge or segmentectomy) is generally performed. Many physicians believe that segmentectomy is superior because it allows for an improved parenchymal margin and nodal sampling. ⋯ In ACOSG Z4032, wedge resection, regardless of the approach, was associated with a smaller parenchymal margin and a lower yield of lymph nodes and rate of nodal upstaging when compared with segmentectomy.

Comparative Study
Midterm results of different surgical techniques to replace dilated ascending aorta associated with bicuspid aortic valve disease.
This study evaluated effectiveness of three different surgical strategies for treating ascending aorta aneurysm, with or without involvement of the aortic root, associated with bicuspid aortic valve (BAV). ⋯ At midterm follow-up, the Bentall operation remains associated with optimal results for the treatment of BAV, despite a worse preoperative presentation. In presence of a mildly diseased or normal aortic root and normal BAV function at the time of operation, less invasive surgical procedures, BAV-sparing, or repair procedures, appear to offer gratifying results.
