The expanding role of mitral valve repair in triple valve operations: contemporary North American outcomes in 8,021 patients.
Although the operative risk of multivalve operations has historically been high, current outcomes are poorly understood. We sought to evaluate factors influencing contemporary results of triple-valve operations using The Society of Thoracic Surgeons Adult Cardiac Surgery Database. ⋯ This large series demonstrates that surgical results of triple-valve operations have continued to improve during the past 18 years. MV and TV repair were associated with improvements in early survival. Although further study is required to understand late outcomes, these data suggest that broader efforts to perform MV repair instead of replacement in this high-risk patient population appear warranted.

We describe the case of a 29-year-old woman with end-stage chronic obstructive pulmonary disease secondary to vascular Ehlers-Danlos syndrome. Because of critical deterioration, respiratory arrest, and complete lung failure, she required urgent implantation of a venovenous extracorporeal membrane oxygenator as a bridge to lung transplantation. After 6 days of extracorporeal life support, a successful bilateral sequential lung transplantation was performed. This is the first case of lung transplantation in a patient with a diagnosis of chronic obstructive pulmonary disease secondary to Ehlers-Danlos syndrome.

Informed consent refers to the process by which physicians and patients engage in a dialogue to explain and comprehend the nature, alternatives, and risks of a procedure or course of therapy. The goal of this study is to better "inform the process of informed consent" by offering empirically derived procedural complication lists that provide objective contemporary data that surgeons may share with patients and families. ⋯ The informed consent process for congenital heart surgery may be served by accurate contemporary data on occurrence of complications. While a threshold rate of occurrence of individual complications may guide the physician, rare but important debilitating complications should also be discussed irrespective of frequency. We propose to better inform the process of informed consent by providing objective complications data.

Aortic wrapping for stanford type A acute aortic dissection: short and midterm outcome.
Conventional surgical treatment of Stanford type A acute aortic dissection (AAD) is associated with considerable in-hospital mortality. As regards very elderly or high-risk patients with type A AAD, some may meet the criteria for less invasive surgery likely to prevent the complications associated with aortic replacement. ⋯ The gold standard in cases of Stanford type A AAD consists of emergency surgical replacement of the dissected ascending aorta. In some cases in which the aortic root is not affected a less invasive surgical approach consisting of wrapping the dissected ascending aorta can be suggested as an alternative.

Real-time magnetic resonance imaging technique for determining left ventricle pressure-volume loops.
Rapid determination of the left ventricular (LV) pressure-volume (PV) relationship as loading conditions are varied is the gold standard for assessment of LV function. Cine magnetic resonance imaging (MRI) does not have sufficient spatiotemporal resolution to assess beat-to-beat changes of the LV PV relationship required to measure the LV end-systolic elastance (EES) or preload-recruitable stroke work (PRSW). Our aim was to investigate real-time MRI and semiautomated LV measurement of LV volume to measure PV relations in large animals under normal and inotropically stressed physiologic conditions. ⋯ Real-time MRI can assess LV volumes, EES, and PRSW at baseline and elevated inotropic states.
