Postcardiotomy cardiogenic shock occurs in approximately 1% of patients. We prospectively evaluated the early and long-term outcome as well as predictors of survival when using temporary extracorporeal membrane oxygenation (ECMO) support. ⋯ Extracorporeal membrane oxygenation is an acceptable technique for short-term treatment of refractory postoperative low cardiac output. It can save the lives of a group of very high risk patients.

Case Reports
Iatrogenic iliac artery rupture and type a dissection after endovascular repair of type B aortic dissection.
We report a case of two iatrogenic complications after endovascular repair of a type B aortic dissection treated for abdominal aortic branch ischemia. A rupture of the common iliac artery occurred first during the procedure. ⋯ The proximal part of the aortic endovascular graft had created a tear in the aortic wall resulting in a retrograde type A dissection. Although aortic endovascular grafting is apparently associated with less morbidity and mortality, potentially lethal complications, both acute and delayed, may arise.

Methods to assess the six competency categories outlined by the Accreditation Council on Graduate Medical Education are essential to allow residency programs to develop reproducible evaluations of their educational curriculum. Current tools to evaluate competencies are insufficient to perform these tasks, particularly in subspecialty disciplines. The key objective of this initiative was to develop and implement an evaluative tool that would provide data to residents and program leadership regarding their performance and to provide the training program with a reliable way to assess this component of the program. ⋯ The 360-degree feedback results provided valuable information for the residents. It also provided our program with a reproducible, quantifiable tool to assess these competencies. Combined with other instruments, the 360-degree feedback was found to be a particularly valuable instrument.

Video-assisted thoracic surgery (VATS) is conventionally performed under single-lung ventilation. A small proportion of patients are often excluded from undergoing VATS because of their inability to tolerate single-lung ventilation. We describe a simple technique of selective lobar lung collapse that may help to recruit additional, selected patients for VATS. ⋯ This technique is simple and safe and requires no expensive disposable devices. Although not essential for most patients undergoing VATS, it deserves to be in the armamentarium of the thoracic surgeon. Further studies will be required to better define its application in clinical practice.

Use of arterial grafts in coronary surgery is based on the excellent patency of the left internal thoracic artery (LITA) and an expectation that other arterial grafts-right internal thoracic artery (RITA) and radial artery (RA)-will give similar patencies, superior to saphenous vein. We examined patencies of arterial grafts in a practice with extensive use for more than 15 years. ⋯ Excellent long-term patencies of arterial grafts are noted, superior to those of vein grafts. Patencies were influenced by conduit, by distribution, and by coronary artery stenosis.
