BACKGROUND Determinants of operative mortality after aortic valve replacement vary with a changing patient population due to advances in operative management and increasing life expectancy. In order to predict current groups of high risk patients, a statistically valid large study population base recruited over a short period of time is required. METHODS(More)
BACKGROUND Renal impairment is one of the predictors of mortality in cardiac surgery. Usually a binarized value of serum creatinine is used to assess the renal function in risk models. Creatinine clearance can be easily estimated by the Cockcroft and Gault equation from serum creatinine, gender, age and body weight. In this work we examine whether this(More)
Due to demographic changes in average life expectancy, the age of patients undergoing cardiac surgery is increasing as well. We have reviewed the short- and long-term outcome in patients over 80 years of age after aortic valve replacement. From 01 Jan 1995 until 31 Dec 1998, 105 patients (76 women, 29 men between 80 and 89 years, median: 83) underwent(More)
There is a trend towards cannulation of the axillary artery for extracorporeal circulation in patients requiring aortic arch surgery. We analyzed the published data comparing axillary and femoral cannulation for safety and outcome. End points were death; stroke, neurologic, and vascular complications; and malperfusion. Femoral cannulation is safe for(More)
OBJECTIVE This study identifies high-risk octogenarians for surgical aortic valve replacement (AVR) because with the current advances in transcatheter valve therapy, a definition of patient selection criteria is essential. METHODS Between 1996 and 2006, 493 consecutive octogenarians with symptomatic aortic stenosis underwent AVR with and without (51%)(More)
PURPOSE Although gelatin-resorcinol-formaldehyde glue has been used to treat acute aortic dissections for some time, concerns about formaldehyde's mutagenicity and carcinogenicity made it imperative to develop a new glue compound. Gelatin-dialdehyde glue was produced by omitting the formaldehyde component and replacing it with two less toxic aldehydes,(More)
BACKGROUND The steadily increasing life expectancy of the population in the Western World, together with the progress in noninvasive diagnostic methods and operating techniques lead to an increase in aortic valve surgery in elderly people. AIM OF THE STUDY Is there an increased risk of adverse perioperative and mid-term outcome for octogenarians and do(More)
Survival rates are a well-known marker for quality performance of a cardiac surgery department, as well as standard of procedures, freedom of reoperation, postoperative complications, length of hospital stay, improvement in New York Heart Association classification and quality of life after surgery. Until recently there has not been any great interest of(More)
Due to demographic changes in average life expectancy, the age of patients undergoing cardiac surgery is increasing. We have reviewed the short- and long-term outcome after aortic valve replacement with or without concomitant coronary artery bypass grafting in patients over 80 years of age. From 1 January 1995 until 30 June 1999, 114 patients (83 women and(More)
BACKGROUND The implantation of stentless valves is technically demanding and the outcome may depend on the performance of surgeons. We studied systematically the role of surgeons and other possible determinants for mid-term survival, postoperative gradients and Quality of Life (QoL) after aortic valve replacement (AVR) with Freestyle stentless(More)
