Details on haemorrhagic and thromboembolic complications during hospital stay. Haemorrhagic or thromboembolic complications occurred in 29 patients with mechanical heart valves, dichotomized according to treatment exposure (therapeutic anticoagulation shown dark grey bars, no therapeutic anticoagulation shown as light grey bars). Complications were adjudicated according to anticoagulation treatment present immediately prior to clinical occurrence or diagnosis of haemorrhagic and thromboembolic complications. The mechanical valve position is indicated by ‘A’, ‘M’, ‘B’, either ‘aortic’, ‘mitral’, or ‘both’. The time-point of occurrence and the type of complication is depicted by coloured arrows (haemorrhagic shown as red, thromboembolic as blue). The classification of complications as intra- or extracranial is shown at the right hand side, ‘I’, intracranial and ‘E’, extracranial. The cross indicates the time-point of in-hospital mortality. The length of hospital stay after the censoring complication is depicted as light grey bars with white horizontal stripes. For definitions of haemorrhagic and thromboembolic complications please see methods. ICH, intracerebral haemorrhage.
