One of my patient who was referred from surgery, was asked on the prophylaxis of endocartitis in view of patient MR and AR conditions.

I do a search on propylaxis and came to know that NICE had published latest guideline on prophylaxis on IE.

And the latest recommendation:

Prophylaxis against infective endocarditis
1.1.3 Antibiotic prophylaxis against infective endocarditis is not recommended:
• for people undergoing dental procedures
• for people undergoing non-dental procedures at the following sites1:
− upper and lower gastrointestinal tract
− genitourinary tract; this includes urological, gynaecological and obstetric procedures, and childbirth
− upper and lower respiratory tract; this includes ear, nose and throat procedures and bronchoscopy.

The recommendation basically altered the view of the need of prophylaxis in any of the surgical procedure.
