The 2007 American Heart Association (AHA) guidelines limited antibiotic prophylaxis (AP) for infective endocarditis (IE) to fewer patients with predisposing cardiac conditions (PCC). We surveyed the American Academy of Pediatrics Section on Cardiology and Cardiac Surgery (AAP SOCCS) on their recommendations for AP for a number of PCC and procedures. We report on those 173 respondents who follow the 2007 AHA guidelines. AP rates for high-risk PCCs clearly meeting AHA criteria ranged from 70.5-89.8%. Conversely, for PCCs which did not meet AHA criteria, prescribing rates varied from <1% to 29.5%. PCC for which AP indication was unclear per guidelines, AP rates similarly varied from 9.9-39.8%. Similar variability is noted in AP for various procedures in setting of high-risk PCC. There is variability in AP prescribing practices among pediatric cardiologists based on both underlying PCC and noncardiac procedures in the setting of underlying cardiac disease.

2007 年美国心脏协会 (AHA) 指南将感染性心内膜炎 (IE) 的抗生素预防 (AP) 限制为较少的易患心脏病 (PCC) 的患者。我们调查了美国儿科学会心脏病学和心脏外科分会 (AAP SOCCS)，了解他们对 AP 对许多 PCC 和程序的建议。我们报告了 173 位遵循 2007 年 AHA 指南的受访者。明确符合 AHA 标准的高风险 PCC 的 AP 率为 70.5-89.8%。相反，对于不符合 AHA 标准的 PCC，处方率从 <1% 到 29.5% 不等。根据指南，AP 适应症不明确的 PCC，AP 率同样在 9.9-39.8% 之间变化。在 AP 中针对高风险 PCC 设置的各种程序注意到了类似的可变性。
