Haematological considerations in patients with cyanotic congenital heart disease: a review.

In patients with cyanotic congenital heart disease (CCHD), the need for prior antibiotic prophylaxis for infective endocarditis is well known to dentists, but not many dentists are aware of the associated haemorrhagic tendencies in such patients. Haemostatic abnormalities associated with CCHD are an important aspect that is often overlooked by both physicians and dentists. We briefly review the literature to highlight the importance of more elaborate haematological evaluation in patients with CCHD, prior to any oral surgical procedures.
