Peri-procedural antibiotic prophylaxis in ventricular septal defect: a case study to re-visit guidelines.

The current American Heart Association (AHA)/American College of Cardiology (ACC) guidelines do not recommend antibiotic prophylaxis for infective endocarditis (IE) in patients with acyanotic congenital valvular heart disease due to lack of any proven benefit and potential harm associated with antibiotics. As recognized by the guidelines, some acyanotic congenital heart disease, such as ventricular septal defects (VSDs), are associated with a high velocity jet and pose a greater risk of peri-procedural endocarditis. We suggest that an acyanotic congenital heart disease with high velocity jet should be considered for antibiotic prophylaxis for IE.
