BACKGROUND: The American College of Cardiology/American Heart Association (ACC/AHA) and the European Society of Cardiology (ESC) have developed guidelines to assist clinicians in making evidence-based decisions. This study compares the ACC/AHA and ESC guidelines for the management of patients with valvular heart disease (VHD). METHODS: The current ACC/AHA and ESC guidelines for VHD, last updated in 2014 and 2012, respectively, were compared by class of recommendation (COR), level of evidence (LOE), and content. RESULTS: The ACC/AHA and ESC VHD guidelines contain 229 and 85 recommendations, respectively. The COR distributions of the ACC/AHA and ESC VHD guidelines were 47.6% vs 44.7% class I [P≤.65]; 46.3% vs 55.3% class II [P≤.16]; and 6.1% vs 0.0% class III [P≤.01], respectively. The LOE distributions were 3.1% vs 0.0% LOE A [P≤.20]; 47.2% vs 10.6% LOE B [P<.001]; and 49.8% vs 89.4% LOE C [P<.001], respectively. The recommendation type distributions were 31.0% vs 2.4% diagnostic [P<.001]; 23.1% vs 16.5% medical therapy [P≤.20]; and 45.9% vs 81.2% interventional/surgical recommendations [P<.001], respectively. The content of the guidelines was similar, with only minor differences in a few recommendations. CONCLUSIONS: The ACC/AHA VHD guidelines contain significantly more recommendations. The distribution of COR was similar, but the ACC/AHA guidelines included more LOE B recommendations and fewer LOE C recommendations, suggesting that the ACC/AHA guidelines place greater emphasis on published data than expert opinion. Overall, the ACC/AHA and ESC guidelines provide similar recommendations, suggesting consistency in practice; however, the relative paucity of LOE A recommendations highlights the need for additional research.
