Replacement of the aortic root with a composite graft containing a prosthetic mechanic valve is the preferred surgical procedure for tailoring the aortic root. The aim of this study is to determine the 5-year experience with the composite root replacement using our new modification of the Bentall technique. ⋯ The flanged composite graft offers excellent long-term results, with very low prevalence of prosthetic-related complications. The new created sinuses and the flange are especially helpful to continue physiologic function of the aortic root.

Deterioration of gas exchange during one lung ventilation (OLV) is caused by both total collapse of the nondependent lung and partial collapse of the dependent lung. A previous report demonstrated that an alveolar recruitment strategy (ARS) improves lung function during general anesthesia in supine patients. The objective of this article was to study the impact of this ARS on arterial oxygenation in patients undergoing OLV for lobectomies. ⋯ Alveolar recruitment of the dependent lung augments PaO2 values during one-lung ventilation.

Review Case Reports
Delayed cardiac tamponade after coronary artery laceration.
Delayed cardiac tamponade after laceration of a coronary artery is unusual and uncommonly reported in the literature. We describe a patient in whom this potentially fatal complication developed 8 days after a stab wound to his chest. In our review of the English language literature we identified only one other report of delayed tamponade after coronary artery laceration.
