The aim of this study is to examine the differences between patients with and without endocarditis who undergo cardiothoracic (valve) surgery. In addition, the investigators will look at the differences between endocarditis patients who undergo surgery, and those who are treated conservatively. The investigatorswill look at incidence and degree of perioperative coagulation abnormalities, as well as transfusion and coagulation factor requirements, heparin resistance, bleeding scores, predictive endocarditis mortality scores, vasopressor-inotrope scores, and relate these where possible to the pathogen causing IE. The investigators will also look at perioperative complications, in particular, thromboembolic events and mortality at 30 and 90 days, and at 1 year.~These outcomes may help optimise perioperative care for high-risk endocarditis patients, and in particular those undergoing valve surgery.
The investigators will compare patients with and without infective ndocarditis undergoing valve surgery and evaluate factors that may help optimise perioperative care of these high-risk patients.
