Objectives: The presence of cerebral haemorrhage (CH) preoperatively is a risk factor of in-hospital cerebrovascular complications post-valve surgery for acute infective endocarditis. However, factors related to cerebrovascular complications in the long term are poorly understood. We reviewed a series of these patients to investigate risk factors of in-hospital and long-term outcomes.
Methods: An institutional series of 148 patients who underwent valve surgery for active infective endocarditis between 2000 and 2016 were enrolled. Patients were divided into 2 groups based on the presence of preoperative CH:CH group (n = 25) and non-CH group (n = 123). Of them, 14 (10%) patients were preoperatively diagnosed with mycotic aneurysm (MA).
Results: The 30-day mortality was 5% with no difference between the 2 groups. The 5-year survival rate was 92% in the CH group and 77% in the non-CH group. Freedom from CH at 5 years was 92% in the CH group and 97% in the non-CH group. There was no difference in the postoperative haemorrhage rate between patients who had surgery within 14 days from the onset of CH and those who had surgery after 14 days. Freedom from CH at 5 years was 99% in patients without MA and 71% in those with MA. The presence of MA preoperatively was the only independent risk factor of postoperative CH (P = 0.002).
Conclusions: Valve surgery for acute infective endocarditis is safe, even in patients with CH preoperatively, regardless of the timing of surgery. Patients with intracranial MA are associated with postoperative CH in the hospital and long term.
