Review Meta AnalysisIs a stentless aortic valve superior to conventional bioprosthetic valves for aortic valve replacement?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether a stentless valve is superior to conventional stented valves when tissue aortic valve replacement is performed. Altogether more than 515 papers were found using the reported search, of which 16 represented the best evidence to answer the clinical question. ⋯ At six months several studies and a meta-analysis have shown superior left ventricular mass regression in the stentless valve groups. However, by 12 months the stented valve groups catch up in terms of mass regression and this significance disappears. So the 'eminent speaker from the floor', was right with his statement, that there have been no definitively proven benefits for stentless valves.

Case ReportsAcute thrombosis of an abdominal aortic aneurysm following intra-aortic balloon pumping.
Acute thrombosis of an abdominal aortic aneurysm is a rare but devastating surgical emergency. We present the first case of a patient with sudden thrombosis of an AAA delayed (more than 24 h) after removal of an intra-aortic balloon pump. ⋯ The patient received an aorto-bifemoral graft. The associations between intra-aortic balloon pump counter-pulsation and abdominal aortic thrombosis are discussed.
